A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• The experimental readjson.s7i library has been removed.
• The new library fixarray.s7i has been added. This library supports arrays with a fixed size. The minimum and maximum index of these arrays is encoded in the type. The functions minIdx(), maxIdx() and length() can be used with an array or the type as parameter. The times operator can be used with: arrayType times elementValue.
• The library msgdigest.s7i has been refactored to use fixed size arrays. The reduction in run-time for some functions is md5: 6%, sha1: 26%, sha256: 21%, sha512: 22%.
• The library lzma.s7i has been refactored to use fixed size arrays. The run-time of the XZ decompression has been reduced by 10%.
• The library jpeg.s7i has been refactored to use the fixed size array type dataBlockType instead of array integer.
• In jpeg.s7i the restart interval handling (with mcuCount) has been improved.
• The libraries deflate.s7i and gzip.s7i have been refactored to use a fixed size array for the sliding window.
• The library aes_gcm.s7i has been refactored to use fixed size arrays for the factor H.
• The interface types for bitStream and huffmanTable have been removed. This way, bitStream and huffmanTable functions are called without dynamic dispatch. This change reduces the run-time of the function readJpeg() by 5.2% (measured with gcc and valgrind and the s7c options -oc3 -O3).
• The templates DECLARE_CcittModifiedGroup3Fax_FUNCTIONS, DECLARE_CcittT6Fax_FUNCTIONS and DECLARE_CcittT4Fax2d_FUNCTIONS have been added to ccittfax.s7i. The templates are instantiated for MSB and LSB bit ordering. This way ccittfax functions work without dynamic dispatch.
• A declaration of the template DECLARE_MIN_MAX has been added to integer.s7i. This template is used to define the functions min() and max() for the types bigInteger, bigRational, float, integer and rational (in bigint.s7i, bigrat.s7i, float.s7i, integer.s7i and rational.s7i respectively).
• Now non-SYMLINK getters and setters in cpio.s7i, tar.s7i and rpm.s7i follow relative symlinks inside the archive.
• Getters for fileMode, mTime, owner and group of symbolic links have been added to cpio.s7i, tar.s7i and rpm.s7i.
• Setters for mTime, owner and group of symbolic links have been added to cpio.s7i, tar.s7i and rpm.s7i.

• The functions removeDotFiles and symlinkDestination have been added to filesys.s7i.
• In encoding.s7i the functions toBase and toBase58 have been fixed to allow encoding "". The functions toBase and fromBase have been improved to work with any digit for 0 (toBase58 encodes 0 with 1).
• In scanfile.s7i the function getLineComment has been fixed to leave line endings unchanged.
• In scanstri.s7i the function getEscapeSequence has been fixed to assume that numeric escape sequences end with a semicolon (;). The function getNumber has been refactored as well.
• A definition of HASHELEMOBJECT has been added to category.s7i.
• The function conv2unicode in the charsets.s7i library has been improved to use a for-each loop.
• A declaration of the function arrayLength has been added to the progs.s7i library. This function is used by the compiler.
• The Seed7 compiler (s7c.sd7) has been improved:
  • The maximum and minimum values in a constant integer array are determined. This way the range of possible values for indexing into this array can be estimated. This allows for the removal of some overflow checks. The run-time of the function md5() has been reduced by 2.6% (measured with gcc and valgrind and the s7c options -oc3 -O3).
  • Now assignments with the times operator like dest := aSize times 0 are optimized to use memset().
  • Assignments to an integer array where the source array contains only zeros are optimized to use memset(). The assignment does realloc the array if the size changes. For fixed size arrays the check of the size and the call of realloc is optimized away.
  • For fixed size arrays index checks are optimized away if the range of possible index values is always inside the array. This optimization reduces the run-time of the function readJpeg() by 7.5% (measured with gcc and valgrind and the s7c options -oc3 -O3).
  • Fixed size array assignments have been improved to omit the copy of minIdx and maxIdx (for fixed size arrays they cannot change with an assignment).
  • The index check for fixed size arrays has been simplified. For these arrays the lower and upper bounds of the index are known at compile time. This optimization reduces the run-time of the function readJpeg() by 7.9% (measured with gcc and valgrind and the s7c options -oc3 -O3).
  • Indexing into an array has been improved for fixed size arrays if the index checks are suppressed.
  • In str_act.s7i the index check for the fixLen substring operation (stri[start fixLen length]) has been simplified.
  • Now the division of product with mdiv is optimized. The division or the multiplication is removed if possible.
  • The recognition of constant expressions has been improved. Constants defined with a parameter list are not considered constant if at least one parameter is not constant.
  • The code generation in set_act.s7i has been improved to avoid adjacent - operators (e.g. number--1).
  • Now a generic function for user defined hashCode function is generated.
  • In int_act.s7i the statistic of suppressed range checks has been improved.
• Regression tests which create adjacent - operators in the generated C code have been added to chkset.sd7.
• In drw_x11.c the graphics driver has been improved to support window titles with Unicode.
• In chkccomp.c test programs have been improved to call XRenderQueryExtension() only if XOpenDisplay("") succeeded.
• In bitdata.s7i the deprecated functions getBitLsb(), getBitsLsb(), peekBitsLsb(), skipBitsLsb(), getBitMsb(), getBitsMsb(), peekBitsMsb() and skipBitsMsb() with a string as parameter have been removed. The functions with the types lsbBitStream and msbBitStream should be used instead.
• Tests for the deprecated bitdata functions with a string as parameter (getBitLsb, getBitsLsb, peekBitsLsb, getBitMsb, getBitsMsb and peekBitsMsb) have been removed from chkbitdata.sd7.
• In huffman.s7i the deprecated functions getHuffmanSymbolMsb(string, ...) and getHuffmanSymbolLsb(string, ...) have been removed. The functions getHuffmanSymbol(msbBitStream, ...) and getHuffmanSymbol(lsbBitStream, ...) should be used instead.
• In strifile.s7i the deprecated function openStrifile() has been removed. The function openStriFile() should be used instead.
• In stritext.s7i the deprecated function openStritext() has been removed. The function openStriText() should be used instead.
• The syntax of hash literals and fixed size arrays has been added to syntax.s7i.
• Generic hashCode functions have been introduced in big_gmp.c, big_rtl.c, bst_rtl.c, int_rtl.c, pcs_rtl.c, set_rtl.c and str_rtl.c. Function prototypes of these functions are defined in big_act.s7i, bst_act.s7i, pcs_act.s7i, set_act.s7i and str_act.s7i. Function pointers to these functions are used by s7c.sd7 in the function action_address.

A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• The compiler has been fixed to be able to compile itself without using the X11 library. Many thanks to Pietro Cerutti for pointing out that compiling s7c.sd7 under FreeBSD failed. Now the function colorPixel() is only used if there is at least one non-empty window object.
• In drw_x11.c the function drwRgbColor() has been improved to raise GRAPHIC_ERROR if it is called without a successful drawInit(). Many thanks to Zachary Menzies for pointing out that the compilation of the Seed7 compiler on AlmaLinux 9 triggered a segmentation fault.
• In tim_win.c the function timAwait has been improved to always raise RANGE_ERROR on february 29th of a non-leap-year. Many thanks to Joe Thompson for pointing out that the chktime.sd7 test failed with MinGW (gcc 8.1). The program chkccomp.c has been improved to define the macro CHECK_NON_LEAP_YEAR_FEBRURARY_29 in version.h if SystemTimeToFileTime() allows february 29th of a non-leap-year.
• The file readjson.s7i with experimental functions to read JSON files has been added. Thanks to Bruce Axtens for driving the attention towards reading JSON.
• The program make7 hase been improved to support commands enclosed in backticks. The change has been made in cli_cmds.s7i.
• The Seed7 compiler (s7c.sd7) has been improved:
• A heap corruption is avoided if the RHS (right hand side) of an assignment changes the target variable. E.g.: aVariable := changeParameter(aVariable); This has been fixed for the types string, bstring, bigInteger, bitset, array, clib_file, struct, window, pointList, sqlStatement, interface, ref_list, process, program, and database.
• The generated code to handle assignments has been improved in arr_act.s7i, big_act.s7i, bst_act.s7i, drw_act.s7i, fil_act.s7i, itf_act.s7i, pcs_act.s7i, pol_act.s7i, prg_act.s7i, rfl_act.s7i, sct_act.s7i, set_act.s7i, sql_act.s7i and str_act.s7i.
• In inline.s7i the function process_inline_func() has been fixed to define the result name. Now the inlining of a result expression works correctly. A test for this has been added to chkhsh.sd7 (function chkInlineHashKeys).
• Now the initialization of window constants assumes an identical pixel encoding if the pixel masks are zero.
• The initialization of POLLOBJECT, REFLISTOBJECT, PROGOBJECT, DATABASEOBJECT, SQLSTMTOBJECT objects has been improved.
• An explanation about the use of special actions for inlining has been added to lib/comp/const.s7i.
• Tests for an assignment where the RHS (right hand side) changes the variable have been added to chkarr.sd7, chkbig.sd7, chkbst.sd7, chkdb.sd7, chkfil.sd7, chkflt.sd7, chkint.sd7, chkset.sd7 and chkstr.sd7. The program chk_all.sd7 has been adjusted for these tests.
• The graphic driver for the browser in drw_emc.c and gkb_emc.c has been improved:
• The handling of the close button of a browser window (X) has been improved. In case the browser decides to delete the window immediately (without asking) the contents of the old window is copied to a new window at the same location and KEY_CLOSE is submitted to the program.
• In gkb_emc.c the variable closePopupStateList and the functions getClosePopupState(), setClosePopupState(), isClosePopupActive() and leavePageWasPressed() have been added. The functions maintain the state after the close button (X) has been clicked (the closePopupState).
• Documentation about the closePopupState has been added to gkb_emc.c.
• The function decodeFocusEvent() has been added to gkb_emc.c.
• Now drwOpen and copyWindow search for the presence of the JavaScript function registerWindow. If it is present, it is invoked with the new window as parameter. The HTML page can define registerWindow to maintain open windows. This way, the HTML page can delete open windows.
• Now a local substitute window is opened if the browser does not allow a new window (popup). This is done in the function openSubstituteWindow().
• The elements is_substitute and parentWindow have been added to the emc_winRecord struct.
• The functions windowExists, copyWindow, clickedWindowLeftPos and clickedWindowTopPos have been added to drw_emc.c.
• The functions clickedXPos and clickedYPos have been improved to work correctly in the browser.
• Freeing a window object in drwFree() now sets the entries in mapIdToWindow, mapIdToCanvas and mapIdToContext to undefined (before, they were set to null).
• In pre_js.js the strategy to determine the program name when a program runs in the browser has been improved.
• In keybd.s7i the deprecated functions getxpos() and getypos() have been removed. The function clickedXPos() and clickedYPos() should be used instead.
• In unicode.s7i the deprecated functions striToUtf16be(), striToUtf16le(), utf16beToStri(), utf16leToStri() and utf7ToStri() have been removed. The functions toUtf16Be(), toUtf16Le(), fromUtf16Be(), fromUtf16Le() and fromUtf7() should be used instead.
• The actions GKB_BUTTON_XPOS and GKB_BUTTON_YPOS have been renamed to GKB_CLICKED_XPOS respectively GKB_CLICKED_YPOS. Changes have been made in keybd.s7i, comp/action.s7i, comp/gkb_act.s7i, primitiv.c, drwlib.h, drwlib.c, drw_drv.h, drw_dos.c, emc_utl.h, emc_utl.c, gkb_emc.c, gkb_win.c and gkb_x11.c.
• In kbd_inf.c and kbd_poll.c the functions kbdGetc() and kbdInputReady() have been improved to call fflush(stdout).
• The X11 function forwarding has been improved to allow direct use of function pointers. Function forwarding is only used if the X11 libraries were missing at build time. The direct use of function pointers can be activated by defining the macro FORWARD_X11_FUNCTION_POINTERS. In this case, logging of X11 functions (that intermediate functions can do) is not possible. These changes introduce the file fwd_x11.h.
• In gkb_emc.c, gkb_win.c and gkb_x11.c the function remove_window() has been improved to call hshExcl only if the window_hash is not NULL.
• In drw_emc.c, drw_win.c and drw_x11.c the function getCloseAction() has been improved to check that actual_window is not NULL.
• In drw_win.c the function drwPut() has been improved to check for RANGE_ERROR at one place.
• Now the empty window is always a singleton. The function generateEmptyWindow() has been introduced in drw_x11.c and drw_emc.c. In drawInit() the singelton is generated with a call of generateEmptyWindow().
• The management of the usage counter (usage_count) for windows, databases and sqlStatements has been improved. Now they are permanent if the usage_count is 0. A usage_count of 0 will neither increase nor decrease. Currently only the empty window is permanent. The changes took place in gkb_emc.c, gkb_win.c, gkb_x11.c, ref_data.c, sql_cli.c, sql_oci.c, sql_post.c and sql_rtl.c.
• The function determineTimeFunctionProperties() has been added to chkccomp.c. This function checks if SystemTimeToFileTime() accepts 2001-02-29 (which does not exist).
• The program chkccomp.c has been changed to always call defineX11rgbToPixelMacro() if X11 is used. This function determines the X11 pixel masks.
• Now the program chkccomp.c defines in version.h that GLX uses an absolute point list with an int size of 16-bits.
• The makefile mk_emccl.mak has been improved to call node.js with which node. Some make utilities trigger a "Permission denied" error if node is called directly.
• The logging in graphic drivers has been improved. Changes have been made in drw_emc.c, drw_rtl.c, drw_win.c, drw_x11.c, drwlib.c, gkb_emc.c, gkb_win.c and gkb_x11.c.
• Logging functions have been added in arr_rtl.c, drwlib.c, drw_rtl.c, drw_emc.c, drw_win.c, drw_x11.c, gkb_emc.c, gkb_win.c, gkb_x11.c, pol_unx.c, ref_data.c and sql_rtl.c.... read more

• Many thanks to Jules Amonith for fixing a typo (Respose was used instead of response).
• Many thanks to Federico Ercole for helping with JavaScript issues. Now clicks on the close button of a browser window can be processed in the program (as KEY_CLOSE). Starting programs from HTML has been improved as well. A terminating program now calls the JavaScript function reloadPage (defined in the HTML document).
• The parser has been improved to stop parsing if the include of an essential file (seed7_05.s7i) fails. Many thanks to Dominik Dorn for reporting that a misspelled seed7_05.s7i triggered many errors.

• Functions for the type pointList have been refactored in graph.s7i and progs.s7i. Before pointList used bstring (BST_...) actions. Now pointList uses PTL_... actions.
• Conversion functions to convert between pointList and bstring have been added to graph.s7i.
• Definitions of PIXEL_ALPHA_MASK, POINT_LIST_INT_SIZE, POINT_LIST_ABSOLUTE and USE_START_MAIN have been added to cc_conf.s7i. The file cmd_rtl.c and the program confval.sd7 have been adjusted accordingly.

• Several improvements have been made for Emscripten (running Seed7 programs in the browser):
  • In drw_emc.c the function drwText() has been improved to draw text with the specified background color.
  • In drw_emc.c the functions drwPArc(), drwPFArc(), drwPFArcChord() and drwPFArcPieSlice have been fixed to correctly draw arcs in the browser if the sweep angle is negative.
  • In drw_emc.c the function drwPut() has been improved to do nothing if the source is an empty pixmap.
  • In drw_emc.c the function drwFree() has been improved to remove the canvas of a sub-window.
  • The function getCloseAction has been added to drw_emc.c.
  • In fil_emc.c the call of setOsProperties has been fixed.
  • The file gkb_emc.c has been improved to allow reading KEY_CLOSE in the browser.
  • The event handling in gkb_emc.c has been improved. Now the events visibilitychange and unload are used for program termination. Upon program termination the JavaScript function reloadPage (defined in the HTML document) is called.
  • The functions decodeBeforeunloadEvent, decodeVisibilitychange and decodeUnloadEvent have been added to gkb_emc.c.
  • The functions startMainButtonPresent, addEventPromiseForStartButton, setupEventPromises, freeEventPromises, asyncButtonClick and executeStartMainOnButtonClick have been added to emc_utl.c
• The Seed7 compiler (s7c.sd7) has been improved:
  • Now unsupported options trigger an error.
  • Now empty temporary files (tmp_*.c) are overwritten.
  • An optimization for bin32(a+b) & constBin32 has been added. The generated code works without overflow checks. Tests for this case have been added to chkbin.sd7.
  • An optimization for bin32(a+b) & constBin32 with bigInteger a and b has been added. The generated code works with integers and without overflow checks.
  • The optimization for ord(aBigInteger mod number1) + number2 has been improved.
  • An optimization for aString[length(aString)] has been added.
  • An optimization that recognizes if aString[start .. stop] always raises an INDEX_ERROR has been added.
  • The code generation for aString[start .. stop] has been improved.
  • An optimization for aString @:= [length(aString)] aChar; has been added
  • The code generated for aString @:= [pos] aChar; has been improved.
  • The optimization of aString &:= str(charExpression); has been improved.
  • An optimization for the string multiplication str(aChar) mult aConstantInteger has been added.
  • An optimization for the division of a product has been added.
  • The code generation of card(bitset(anInteger)) has been refactored. Tests for this case have been added to chkset.sd7.
  • The conversion from a bin32 to a single-precision floating-point number has been optimized. Tests for this case have been added to chkbin.sd7.
  • Image constants are now stored in the target pixel encoding. The compiler will convert the pixels of an image if necessary. The target pixel encoding is specified with the configuration values RED_MASK, GREEN_MASK, BLUE_MASK and ALPHA_MASK.
  • The actions PLT_BSTRING, PLT_CMP, PLT_EQ, PLT_HASHCODE, PLT_NE, PLT_POINT_LIST and PLT_VALUE are listed as pure functions.
  • The code generation for the actions STR_ELEMCPY, SQL_CPY_DB and SQL_CPY_STMT has been refactored.
  • The configuration value USE_START_MAIN is used to produce code for the browser. In this case, main() will check if a startMain button exists in the HTML page. If no startMain button exists, the program will start. If a startMain button exists, the program will wait until it is pressed. After the button is pressed, the function startMain() will be invoked (which executes the rest of the program).
  • The pointList data is now stored in the target encoding. The compiler will convert a pointList if necessary. The target encoding is specified with the configuration values POINT_LIST_INT_SIZE and POINT_LIST_ABSOLUTE.
  • The pointList coordinates are now aligned for Emscripten HEAP32 access. If the macro POINT_LIST_ALIGNMENT is defined, an alignment is necessary. In this case, the function pltAlign() will carry out the alignment. If POINT_LIST_ALIGNMENT is not defined, pltAlign() will just forward its parameter.
  • In type.s7i POINTLISTOBJECT and REFLISTOBJECT have been added to the heapCategories set.
  • Unused code has been removed from flt_act.s7i and str_act.s7i.
  • The functions optimize_big_mod_dividend, process_const_bin_and, optimize_div_of_product, pointListLiteral, process_str_push, process_str_elemcpy_last_char, process_str_idx_last_char, process_plist_declaration, pixelEncodingIdentical, pixelEncodingWithoutAlphaChannel, swapRedAndBlue, fixPixels, pointListEncodingIdentical, toPointListAbsolute, toPointListRelative16, toPointListRelative32, toTargetPointListBstring, init_plist_constants and assign_plist_constants have been added.
• The functions createSymlink and winCopySymlink have been added to cmd_win.c. Tests for symlinks have been added to chkcmd.sd7.
• The functions set_excl (in setlib.c) and setExcl (in set_rtl.c) have been improved to resize the set. Tests for excl(bitset, integer) have been added to chkset.sd7.
• In set_rtl.c and setlib.c the heap statistic has been fixed for several operations.
• The logging infrastructure has been improved. Now the macros LOG_FUNCTIONS and VERBOSE_EXCEPTIONS can be set to -1. With -1 logging is deactivated even if LOG_FUNCTIONS_EVERYWHERE respectively VERBOSE_EXCEPTIONS_EVERYWHERE is active. Support to activate the function logMessage in every file with LOG_MESSAGES_EVERYWHERE has been added as well.
• An explanation of the logging infrastructure has been added to common.h.
• Interpreter and compiler have been improved to support the actions BIN_BIT_LENGTH, BIN_LOWEST_SET_BIT, DRW_GET_PIXEL_DATA_FROM_ARRAY, PLT_BSTRING, PLT_CMP, PLT_CPY, PLT_EQ, PLT_HASHCODE, PLT_NE, PLT_POINT_LIST and PLT_VALUE.
• The unused action LST_ELEM has been removed form interpreter and compiler.
• Support for the category POINTLISTOBJECT has been added to interpreter and compiler.
• The functions drwGetPixelDataFromArray and pltAlign have been added to drw_rtl.c.
• In gkb_win.c the function gkbInputReady() has been improved to work correctly if GetMessageW() does not return the message promised by PeekMessageW(). Now it is generally assured that only fields of the correct message are accessed.
• In drw_x11.c the function drwConvPointList has been fixed to work for an empty pointList.
• In drw_dos.c, drw_emc.c, drw_win.c, drw_x11.c and drw_drv.h the function drwImage has been improved to consider an alpha channel.
• In cmd_rtl.c the function doReadLink has been refactored to distinguish between link_size (from link_stat.st_size) and dest_buffer_size. This simplifies the check for a truncation.
• Instances of the words minimal and maximal have been replaced with minimum and maximum in several files.
• The Seed7 build system has been improved:
  • The build with emcc under Linux and Windows has been fixed. The makefiles mk_emccl.mak and mk_emccw.mak and the program chkccomp.c have been adjusted. Now a stack-size is specified for 'make utils'.
  • Now chkccomp.c uses a better way to determine group and user functions.
  • Now size and signedness of gid_t and uid_t are determined in chkccomp.c. The macros GID_T_SIZE, GID_T_SIGNED, UID_T_SIZE and UID_T_SIGNED are defined accordingly.
  • In chkccomp.c global variables for sizeof_int, sizeof_long, sizeof_long_long, sizeof_pointer, sizeof_float and sizeof_double have been introduced.
  • In chkccomp.c the function testOutputToBuffer() has been improved to work correctly if the first character read is a newline. A check for the buffer size has been added to testOutputToBuffer() as well.
  • Now chkccomp.c determines if the function symlink() is present and sets the macro HAS_SYMLINK accordingly.
  • Performance measurements for left shift have been added to chkccomp.c. The macros LSHIFT_BUILTIN_MUL_TIME, LSHIFT_TWO_ARG_CHECKS_TIME, LSHIFT_ONE_ARG_CHECK_TIME, LSHIFT_RESULT_CHECK_TIME and LSHIFT_NO_CHECK_TIME are defined accordingly.
  • In chkccomp.c check if ferror() returns true after reading from write only file (FERROR_WRONG_WHEN_READING_FROM_WRITE_ONLY_FILE).
  • The number of C compiler warnings in chkccomp.c has been reduced.
  • The functions checkOverflowSignal, timeLShiftOverflowCheck, determineGrpAndPwFunctions and determineCurrentWorkingDirectory have been added to chkccomp.c.
  • The program chkccomp.c has been improved to define the macros GID_T_SIZE, GID_T_SIGNED, UID_T_SIZE, UID_T_SIGNED, GROUP_0_NAME, USER_0_NAME, FERROR_WRONG_WHEN_READING_FROM_WRITE_ONLY_FILE, HAS_SYMLINK, POINT_LIST_INT_SIZE, POINT_LIST_ABSOLUTE, POINT_LIST_ALIGNMENT, LSHIFT_BUILTIN_MUL_TIME, LSHIFT_TWO_ARG_CHECKS_TIME, LSHIFT_ONE_ARG_CHECK_TIME, LSHIFT_RESULT_CHECK_TIME and LSHIFT_NO_CHECK_TIME.
• In several files flag macros for logging have been introduced:
  • In pol_sel.c and pol_unx.c the flag macro DUMP_POLL has been introduced. This macro decides if detailed information about pollData should be written.
  • In soc_rtl.c the flag macro SHOW_ADDRINFO has been introduced. This macro decides if detailed information about the address info should be written.
  • In sql_oci.c and sql_post.c the flag macro SHOW_DETAILS has been introduced. This macro decides if detailed information should be written.
  • In sql_oci.c the flag macro DEBUG_LONG_CALLBACK has been introduced. This macro decides if detailed information about a long callback should be written.

A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• The FAQ has been improved. Many thanks to Liam O'Brien for creating a list suggested changes. Thanks for helping to improve Seed7 in general.
• Support for symbolic links under Windows has been added:
  • Symbolic link reparse points and mount reparse points are both treated as symbolic links.
  • The interface does not distinguish between directory symbolic links and normal symbolic links. A normal symbolic link may refer to a directory and readDir(symlink) reads the directory contents (like it does under Linux/Unix/BSD).
  • The functions fileType() and fileTypeSL() have been improved to
    work under Windows like they do under Linux/Unix/BSD:
    • fileType() follows symbolic links and returns the file type of the final destination.
    • fileTypeSL() returns FILE_SYMLINK for symbolic links. For all other file types fileTypeSL() works like fileType().
    • fileTypeSL() does return FILE_SYMLINK only if readLink() works correctly.
    • fileTypeSL() has been fixed to return FILE_DIR for the emulated root directory and FILE_ABSENT if the file path cannot be mapped to a system path.
  • The functions readLink(path) and readLink(path, ABSOLUTE) have been improved to read the symbolic links of Windows. The function readLink(path) can read relative and absolute symbolic links. Both functions can read dangling symlinks. The functions are implemented with DeviceIoControl(). If DeviceIoControl() is not available (HAS_DEVICE_IO_CONTROL is not defined), they raise FILE_ERROR.
  • The functions getFileMode(path), setFileMode(path), getOwner(path), setOwner(path), getGroup(path), setGroup(path) and readDir(path) have been improved to follow symlinks under Windows (like they do under Linux/Unix/BSD).
  • Owner and group of the emulated root directory is "root".
  • The function moveFile() has been improved to avoid following symlinks under Windows (like it does under Linux/Unix/BSD).
  • The function symlink() has been improved to allow the creation of relative and absolute symbolic links under Windows. Under Windows administrator rights or the developer mode are necessary to create symbolic links.
• Several file functions have been improved:
  • The function getCTime(path) has been improved to return the change time instead of the creation time in Windows (like it does in Linux/Unix/BSD).
  • The file owner and group functions have been improved to avoid localized user and group names under Windows.
  • The function finalPath(path), which follows a symbolic link chain, has been added to the osfiles.s7i library.
  • The functions getFileMode(path, SYMLINK), getATime(path, SYMLINK), getMTime(path, SYMLINK), setMTime(path, time, SYMLINK), getOwner(path, SYMLINK), setOwner(path, owner, SYMLINK), getGroup(path, SYMLINK) and setGroup(path, group, SYMLINK) have been added to the osfiles.s7i library. These functions work only for symbolic links and get or set symbolic link data. They raise FILE_ERROR if 'path' does not refer to a symbolic link.
  • The functions getFileMode(fileSys, path, SYMLINK), getMTime(fileSys, path, SYMLINK), getOwner(fileSys, path, SYMLINK) and getGroup(fileSys, path, SYMLINK) have been added to the filesys.s7i library.
  • The functions copyFile(), cloneFile() and moveFile() have been improved to prohibit that a dangling symlink is overwritten.
  • In osfiles.s7i and filesys.s7i the function fileMode(path) is deprecated now. The function getFileMode(path) should be used instead.
  • The files ar.s7i, cpio.s7i, ftpserv.s7i, process.s7i, rpm.s7i, tar_cmds.s7i, tar.s7i and zip.s7i have been altered to use getFileMode(path) instead of the deprecated fileMode(path).
• The Seed7 build system has been improved:
  • The makefiles mk_msys.mak, mk_nmake.mak, mk_mingw.mak and mk_mingc.mak have been improved to support 32-bit and 64-bit C compilers.
  • Now, definitions of the library names LIBINTL_DLL, LIBEAY32_DLL, LIBCRYPTO_DLL and LIBSSL_DLL are written to version.h only under Windows.
  • The build tries to load dynamic/shared libraries and logs if they are present or not.
  • For dynamic/shared libraries with an absolute path the build logs, if they are 32-bit or 64-bit.
  • The functionality of setpaths.c has been moved to chkccomp.c.
  • The file setpaths.c has been removed.
  • The files makefile, mk_bcc32.mak, mk_bccv5.mak, mk_clang.mak, mk_clangw.mak, mk_cygw.mak, mk_djgp2.mak, mk_djgpp.mak, mk_emccl.mak, mk_emccw.mak, mk_freebsd.mk, mk_icc.mak, mk_linux.mak, mk_mingc.mak, mk_mingw.mak, mk_msvc.mak, mk_msys.mak, mk_nmake.mak, mk_osxcl.mak, mk_osx.mak, mk_tcc_l.mak and mk_tcc_w.mak have been changed to work without setpaths.c and to call chkccomp with the parameters of setpaths (S7_LIB_DIR, SEED7_LIBRARY and CC_ENVIRONMENT_INI).
  • The search for the SQLite include file in chkccomp.c has been improved to continue if the include file is not in C:/sqlite.
  • The directory seed7/bin has been added as possible place of the sqlite3.dll (or .so).
  • Tests for the presence of the functions CreateSymbolicLinkW(), GetFinalPathNameByHandleW(), DeviceIoControl(), GetFileInformationByHandleEx() and lutimes() have been added to chkccomp.c.
  • In chkccomp.c global variables for buildDirectory, s7LibDir and seed7Library have been introduced.
  • The functions testOutputToBuffer(), determineCurrentWorkingDirectory(), mapCodePageToUtf8(), mapToUtf8(), canLoadDynamicLibrary(), pointerSizeOfDynamicLibrary(), getCodePage(), setS7LibDir(), setSeed7Library() and setPaths() have been added to chkccomp.c.
• The Seed7 compiler (s7c.sd7) has been improved:
  • Now, it writes warnings if parameter aliasing can happen. A function triggers parameter aliasing if two reference parameters refer to the same value and one of them is changed in the function. In this case the other reference parameter changes as well.

A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• The FAQ concerning break and continue has been improved.
• Chapters about assignment and constants have been added to the tutorial, which is part of the manual. A description of the function fraction() has been added to the chapter about predefined types.
• The new library archive_base.s7i has been added. This library defines common functions for file archives. It currently defines the function readDir() which is used by the archive libraries ar.s7i, cpio.s7i, rpm.s7i, tar.s7i and zip.s7i.
• In the zip.s7i library the function readDir() has been improved to work for absolute paths (by calling readDir() from archive_base.s7i).
• Several improvements have been made in the rpm.s7i library:
  • The signature section digests are checked when the RPM file is opened.
  • The payload digests are only checked if the payload is used.
  • Provided and required dependencies are read when the RPM file is opened.
• The compiler (s7c.sd7) has been improved:
  • It recognizes if an array index access would always raise INDEX_ERROR. This is done for a constant array and with the range of possible index values.
  • The optimization of the floating point power operator with an integer exponent has been improved. There are cases where the base is constant, and the range of possible exponents allows a simplification.
  • The optimization of the floating point left and right shift operators has been improved. It considers cases where the number that needs to be shifted is constant and cases where nothing is constant. In both situations the range of possible shift amounts allows simplifications.
  • The optimization of A * B ** C with A and B float and C integer, has been improved. This considers cases where B is a power of two and the range of possible exponents C allows a simplification.
  • It is recognized if the integer left shift operator would always raise OVERFLOW_ERROR. Depending on the range of possible values for the shift amount and the value to be shifted, this optimization is made.
  • The number of checks for OVERFLOW_ERROR and NUMERIC_ERROR of the integer power operator has been reduced. Depending on the range of possible values for base and exponent, some checks can be omitted.
  • Now the range of possible integer values is determined for the expression ord(aBigInteger mod 2_ ** n).
  • Now the range of possible integer values is determined for the length of a sub-string.
  • The generated code for 'elsif FALSE then end if' as been fixed.
  • String index checks are optimized away if the range of possible index values always remains inside a constant string.
  • Computing the length of a fixLen substring has been optimized (e.g.: length(aString[A fixLen B]) will always return B).
  • The optimization of the string length function has been changed to sum up the length of the components as integers.
• The test suite has been improved to increase the code coverage of the compiler.

• In flt_rtl.c the function fltLdexp() has been improved to work correctly for infinity, even if ldexp() does not.
• The program chkccomp.c has been improved to determine LDEXP_OF_INFINITY_OKAY (which defines if ldexp() works for infinity).
• Documentation comments have been improved in null_file.s7i.... read more

A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• The make7 example program has been improved to support quoted dependencies (changes have been made in makedata.s7i). A warning is written if the quoted dependency does not end with ", or when it is not followed by whitespace.
• The comanche web-server example program has been improved:
  • CGI scripts with shebang are supported now. Shebang means that the first line of the script starts with #! and is followed by the command (and possible options) to interpret the script.
  • Now the root directories for HTML files (html-dir) and CGI files (cgi-dir) are converted to an absolute path.
  • On startup of comanche, the current working directory is changed to the root directory for CGI files (some CGI scripts need this).
  • The new option -c can be used to specify the cgi-name used in the HTTP(S) requests. If cgi-name is "", the cgi-name is taken from cgi-dir. Without -c, the default cgi-name of "/cgi-bin/" is used.
  • The new parameter env-file can be used to specify a property file with environment variables to be defined.
  • The help text written with the option -? or -h has been improved.
  • Definitions of the environment variables REQUEST_METHOD, CONTENT_LENGTH and DOCUMENT_ROOT have been added (in http_response.s7i). These environment variables are used by CGI scripts.
• An explanation about the compilation to a dll/so has been added to the FAQ.
• An explanation of the fixLen sub-string has been added to the manual.

• The compiler has been improved to generate better code for insert() (insert elements into an array). For arrays of plain values (e.g. array integer) unnecessary copying of data will be avoided now. Changes have been made in arr_act.s7i, expr_util.s7i, arr_rtl.c and arr_rtl.h.
• The library propertyfile.s7i has been improved so that EOF terminates a property key or value.
• The functions assignConfigValue() and readConfig() have been added to the cc_conf.s7i library.
• In bitdata.s7i the close() function for LSB/MSB bit streams has been fixed to also work near the end of the file and for MSB bit streams.
• In bitdata.s7i the function gets() has been improved so that a maxLength of 0 sets the position to the beginning of the next byte and returns an empty string. If bytePos is beyond the length of the string, an INDEX_ERROR is avoided.
• In echo.s7i, editline.s7i, line.s7i, strifile.s7i and stritext.s7i the function gets() has been improved to always raise RANGE_ERROR for a negative maxLength. A maxLength of 0 always returns an empty string.
• In png.s7i reading of PNG chunks has been refactored.
• In gzip.s7i, iobuffer.s7i, lzma.s7i, strifile.s7i, xz.s7i and zstd.s7i the function seek() has been improved to raise RANGE_ERROR for positions <= 0.

• In chkstr.sd7 the tests for the functions lower() and upper() have been improved to use expression arguments.
• In chkbig.sd7 tests for the bigInteger sci operator have been added.
• Tests for close() of LSB/MSB bit streams have been added to chkbitdata.sd7.
• The program chk_all.sd7 has been adjusted to the changes in chkbig.sd7 and chkbitdata.sd7.

• In gzip.s7i the deprecated functions openGunzipFile(aFile) and openGzipFile(aFile) have been removed.
• In arr_rtl.c the function arrInsertArrayTemp() has been added, and the function arrInsertArray() has been changed to leave the 'elements' array as is.
• The "clean" target of the makefiles has been improved to only remove the libraries created by the same makefile.
• The library names in mk_emccl.mak and mk_emccw.mak have been changed from .a to _emc.a. Additionally, the file ../bin/cc_conf_emcc.prop is created, when running make. This allows the Emscripten version of Seed7 to be installed parallely to the normal Seed7 installation.
• The makefiles mk_mingw.mak and mk_nmake.mak have been improved to avoid the "file too big"/"too many sections" error.
• Documentation comments have been improved in bitdata.s7i, echo.s7i, editline.s7i, keybd.s7i, line.s7i, osfiles.s7i, stritext.s7i, tls.s7i, arr_rtl.c, drwlib.c and kbdlib.c.... read more

A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• The drivers used in the browser (when Seed7 is compiled with Emscripten) have been improved (in con_emc.c, drw_emc.c, fil_emc.c, gkb_emc.c, tim_emc.c and emc_utl.c). Now graphic Seed7 programs can be compiled to JavaScript and Webassembly to run them in the browser.
• A new sub-string operation with a guaranteed length (fixLen) has been introduced. E.g.: "abcde"[2 fixLen 3].
• 30 libraries have been adjusted to use the fixLen sub-string. The guaranteed sub-string length assures that conversions like bytes2Int() do not get data that is too short.
• The library zip.s7i has been fixed to work correct if a descriptor signature follows the deflated data.
• The library jpeg.s7i has been refactored to use the segment length for reading a segment into a string.
• A close() function for LSB and MSB bit streams has been addded to bitdata.s7i. The close() sets the the position of the underlying file directly after the bit stream. This is used by the function inflate() (in the inflate.s7i library).
• The function flush() has been added to the tee.s7i library.
• Several characters in the fonts stdfont10.s7i, stdfont12.s7i, stdfont14.s7i, stdfont16.s7i, stdfont18.s7i, stdfont20.s7i, stdfont24.s7i, vecfont10.s7i and vecfont18.s7i have been improved.
• Interpreter and compiler have been improved to support the action STR_SUBSTR_FIXLEN.
• The compiler (s7c.sd7) has been improved:
  • Support for arcs with thickness has been added (action DRW_PFARC).
  • Code that reports a GRAPHIC_ERROR is now generated.
  • The optimizations for string sub-strings ("abcde"[2 len 3] and "abcde"[2 fixLen 3]) have been improved.
  • The optimizations for combinations of sub-string and conversion to integer (e.g.: bytes2Int(stri[5 fixLen 4], UNSIGNED, LE) ) have been improved.
  • The size of the generated init_values function has been reduced.
  • If requested by USE_DO_EXIT, the function doExit() is called at the end of the program.
  • Profiling data is stored in allocated memory instead of an array. Some C compilers had problems with the array approach.
• The documentation in doc/faq.htm, doc/faq.txt, src/read_me.htm and
  src/read_me.txt has been updated.
• More detailed error messages have been introduced in chkbig.sd7, chkint.sd7 and chkset.sd7.
• Tests in chkint.sd7, chkstr.sd7 and chkidx.sd7 have been improved to check the new sub-string function (fixLen) with and without a subsequent conversion to integer.
• Tests in chkidx.sd7 have been refactored to use if-statements instead of using an ok variable.
• An optional event tracing has been added to con_win.c.
• The event tracing in drw_win.c and gkb_win.c has been improved.
• The program chkccomp.c has been improved to determine SYSTEM_RESULT_FOR_RETURN_0 in a way that works also with Emscipten.
• The test programs to determine LIMIT_FMT_E_MAXIMUM_FLOAT_PRECISION and LIMIT_FMT_F_MAXIMUM_FLOAT_PRECISION in chkccomp.c have been improved to define the large array outside of main (Emsripten needs this).
• In common.h the format strings for OS_OFF_T have been changed to prefer the long format if sizeof(int) = 4 and sizeof(long) = 4.
• An include of traceutl.h has been added to actlib.c, biglib.c, blnlib.c, bstlib.c, chrlib.c, conlib.c, drwlib.c, fillib.c, fltlib.c, intlib.c, pcslib.c, pollib.c, setlib.c and strlib.c. This allows enabling LOG_FUNCTIONS with strict C compilers.
• The function printSet() has been added to set_rtl.c. This function is used in set_rtl.c as replacement for prot_set() when LOG_FUNCTIONS is enabled. This allows logging in compiled programs.
• Logging functions have been improved in arr_rtl.c, con_win.c, drw_win.c, drw_x11.c, fil_rtl.c and gkb_win.c.
• Occurrances of exit() and atexit() have been replaced by os_exit() respectively os_atexit(). This way, the makefiles mk_emccl.mak and mk_emccw.mak can define os_exit() and os_atexit() to use doExit() and registerExitFunction() instead of the default functions.
• JavaScript specific functions have been moved from fil_unx.c to new file fil_emc.c.
• Keyboard functions have been moved from drw_emc.c to the new file gkb_emc.c.
• The JavaScript keyboard drivers in con_emc.c and gkb_emc.c have been improved to work with synchronous I/O although JavaScript works asynchronous in the browser.
• In the new file tim_emc.c the function timAwait() has been introduced. This function saves keypresses that happen during the wait (it works together with the keyboard drivers from con_emc.c or gkb_emc.c).
• The new file emc_utl.c has been introduced. This file contains registerExitFunction() and doExit() which replace atexit() and exit() under Emscripten. It also defines enqueue() and dequeue() which are used during timAwait() to queue keypresses. And finally, it defines mapKeyNameIdToKey() which is used by the keyboard drivers.
• Functions to register and execute callbacks have been added to pre_js.js.
• The makefiles mk_emccl.mak and mk_emccw.mak have been improved to use the linker options ASYNCIFY, ASYNCIFY_STACK_SIZE and EXIT_RUNTIME. The new files emc_utl.c, fil_emc.c, tim_emc.c and gkb_emc.c have also been added.
• JavaScript strings in the .c files have been refactored to use " instead of '.
• The definition of USE_DO_EXIT has been added to cc_conf.s7i. The file cmd_rtl.c and the program confval.sd7 have been adjusted accordingly.
• The keyboard driver gkb_x11.c has been improved to work correctly when the keyboard layout is switched.
• Documentation comments have been improved in string.s7i, str_rtl.c and strlib.c.... read more

A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• The libraries pixmap_file.s7i and graph_file.s7i have been improved to draw to the correct graphic window. Many thanks to Anders Carstensen for pointing out that text was written into the wrong window and for providing a test program.
• Answers to three new questions have been added to the FAQ. Answers to existing questions have been improved. Many thanks to Zachary Menzies for pointing out a problem with two dimensional arrays and for providing a test program.
• An unclosed <i> tag has been removed from the manual. Thanks to ifethereal for pointing out this error. Several other places with illegal HTML in doc/manual.htm have also been fixed.
• The function getXmlTagHeadOrContent() has been improved in scanfile.s7i and scanstri.s7i. Now, tag names start with a letter or underscore (_), and the function can read XML contents that start with the character '<' (like < <= or <> ). In this case, the character < is read as character reference (&lt;).
• An explanation of the exception declaration has been added to the manual.
• The search for the X11 Xrender extension has been improved. In chkccomp.c the function determineX11Defines() has been improved. Declarations have been moved from x11_x.h to the new file x11_rend.h. Adjustements have been made in drw_x11.c and fwd_x11.c.
• Two code pages for APL symbol encoding have been added to charsets.s7i. The graphic representation of the character '\a' (bell) has been changed from '\16#25cf;' to '\16#2022;' in all code sets.

• In itflib.c, the function itf_create() has been improved to raise the exception ACTION_ERROR if the source struct is NULL.
• The prototypes of the functions conWrite() and stri_to_bstriw() have been changed to work with constant strings.... read more

A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• Seed7's approach to avoid double library includes has been improved. Many thanks to Zachary Menzies for reporting the problem (a second library with the same name but in a different directory was not included) and for providing a test case to trigger it. The new mechanism uses the absolute path of a library to determine if it already has been included. Now the map of included libraries is not part of the compiled executable anymore. Changes have been made in seed7_05.s7i, analyze.c, data.h, infile.c, infile.h, libpath.c, libpath.h, prclib.c and prg_comp.c.
• The new library htmldom.s7i has been added. This library contains an improved HTML DOM parser. Many thanks to OddCitron1981 for suggesting to parse some of the wild HTML out there on the web. The functions readHtmlNode() and readHtml() have been moved from xmldom.s7i to htmldom.s7i. The type htmlDocument and the function readHtmlContainerSubNodes() have been added. Improvements of HTML scanning functions were also made due to this suggestion. The new HTML parser considers several things special for HTML:
  • Tag names and attribute names are converted to lower case.
  • There are alternate end tags for tags with optional closing tag.
  • Attributes without value get "" as value.
  • The <!DOCTYPE data is not handled as xmlNode.
  • Closing tags without opening tag are left in as is.
• The HTML scanning functions in scanfile.s7i and scanstri.s7i have been improved:
  • HTML tag attributes without value are allowed now.
  • Reading of HTML tag attributes now stops at the end of tag character (>).
  • CDATA sections are considered now.
  • The functions getXmlTagHeadOrContent(), getSymbolInXmlTag(), getHtmlAttributeValue() and getNextHtmlAttribute() have been improved.
  • The function getXmlCdataContent() has been added.
• A chapter about for-until-loops has been added to the manual.
• The makefiles and the compiler (s7c.sd7) have been improved to avoid linking unused system libraries (e.g. with -lm). Changes have been done in cc_conf.s7i, comp/action.s7i, comp/flt_act.s7i, comp/library.s7i, s7c.sd7, cmd_rtl.c and in the makefiles.
• The bas7.sd7 (basic interpreter) example program has been improved.
  • Now, it is possible to do a string multiplication with the * operator. E.g.: "ha"3 results in "hahaha" and "ab"2+"xy"*3 results in "ababxyxyxy".
  • Now, the RPT$ function is checked for a negative factor.
• The wiz.sd7 example program has been refactored. The functions treasureNumber() and vendorDies() have been introduced.
• The bigfiles.sd7 example program has been improved to limit the length of the result list.
• The compiler has been improved:
  • Now, unused system libraries are not linked to the executable.
  • In comp/flt_act.s7i the implementation of FLT_DECOMPOSE has been improved and float comparisons set the flag mathLibraryUsed, if the implementation requires it.
  • Two functions named appendLibrary() have been added to s7c.sd7. These functions avoid that a system library is linked twice.
  • In comp/action.s7i calls of BIG_... actions now set the flag bigintLibraryUsed and calls of FLT_... actions (that need the math system library) now set the flag mathLibraryUsed.
  • The flags bigintLibraryUsed and mathLibraryUsed have been added to comp/library.s7i.
• In xmldom.s7i the writeXml functions have been refactored. Unnecessary definitions of writeXml have been removed.
• Definitions of SYSTEM_BIGINT_LIBS and SYSTEM_MATH_LIBS have been added to cc_conf.s7i. The definition of ADDITIONAL_SYSTEM_LIBS has been removed. SYSTEM_BIGINT_LIBS and SYSTEM_MATH_LIBS are used in confval.sd7 and s7c.sd7.
• Several improvements in chkccomp.c have been done:
  • Now SYSTEM_MATH_LIBS and LINKER_OPT_DYN_LINK_LIBS are considered. This helps to avoid linking unused libraries.
  • ADDITIONAL_SYSTEM_LIBS has been renamed to SYSTEM_BIGINT_LIBS.
  • Now, it checks if fileno() succeeds after a successful call of popen() (this fixes a problem with Emscripten).
  • The function appendOption() has been improved.
  • The type of several indices has been changed from int to unsigned int (this reduces the number of C warnings).
  • The value LINKER_OPT_DYN_LINK_LIBS is now added to a corresponding list of system libraries if dynamic linking at run-time is necessary.
• In cmd_rtl.c the function doReadLink() has been improved to work also for symlinks in the Linux /proc filesystem (in /proc the stat() function reports a symlink size of 0).
• The macro environmenStrncmp has been renamed to environmentStrncmp.
• The function getProgramPath() has been moved from analyze.c to cmd_rtl.c. Additionally it has been improved and renamed to getAbsolutePath().
• In cmd_unx.c the function getExecutablePath() has been improved to use doReadLink() and to return a straightened absolute path (the special directories "." and ".." are interpreted according to their conventional meanings).
• The functions concatAndStraightenPath() and straightenAbsolutePath() have been added to str_rtl.c.
• In infile.c the functions open_infile(), close_infile(), open_string() and remove_prog_files() have been renamed to openInfile(), closeInfile(), openString() and removeProgFiles() respectively. Now openInfile() and openString() return a boolType result to indicate the success.
• In libpath.c the functions find_include_file(), append_to_lib_path(), init_lib_path() and free_lib_path() have been renamed to findIncludeFile(), appendToLibPath(), initLibPath() and freeLibPath() respectively. The functions initIncludeFileHash(), shutIncludeFileHash() and openIncludeFile() have been added. The added functions maintain a hashmap of already included files.
• In prclib.c the function prc_include() has been adjusted to call the new function that avoids double includes. Now the 2nd parameter of the action PRC_INCLUDE contains the file name to be included.
• In striutl.c the functions stri_to_os_utf8(), conv_to_os_stri() have been improved to return a boolType result that indicates success.
• Logging functions have been added to strlib.c.
• Documentation comments have been improved in cc_conf.s7i, html.s7i, osfiles.s7i, scanfile.s7i, scanstri.s7i, cmdlib.c, cmd_rtl.c, hshlib.c and hsh_rtl.c.... read more

A new version of the extensible programming language Seed7, has been released.
See: http://seed7.sourceforge.net

Changelog:

• The linking of PostgreSQL has been improved. Many thanks go to SiliconWizard, for pointing out linking problems and for helping to investigate them. The function findPgTypeH() has been added to chkccomp.c. Now the search for pg_type.h and pg_type_d.h does not include postgres.h. In sql_post.c the include of the file postgres.h has been removed.
• The wiz.sd7 example program has been refactored. Now it can be compiled. Many thanks go to Vasiliy Tereshkov, for reporting the compilation problem. Additionally, several improvements of wiz.sd7 have been done.
• The functions expm1() and log1p() have been added to the math.s7i library. Many thanks go to Sanjay Jain for pointing out that they were missing.
• In wrinum.s7i the functions str(ENGLISH, number) and str(GERMAN, number) have been improved to work correctly for zero.
• In forloop.s7i the definition of for-until-loops has been improved, such that the loop variable never gets a value outside of the range. The definition of for-loops has been changed to invoke the loop-body just at one place. Since the loop body is inlined, this does shorten the generated code.
• Tests for for-loops have been added to chkprc.sd7.
• The compiler (s7c.sd7) has been improved to generate better code for the actions BLN_TERNARY, REF_ADDR, REF_SELECT and SET_ELEM (changes were done in bln_act.s7i, ref_act.s7i and set_act.s7i).
• The compiler has been improved (in comp/enu_act.s7i), to check for a possible RANGE_ERROR, if an integer is converted to an enumeration value (action ENU_ICONV2).
• The compiler has been improved to optimize expressions like ord(aBigExpression mod aPowerOfTwo).
• The function chkBigOrdWithBigMod has been added to chkbig.sd7. This function checks the optimizations done with expressions like ord(aBigExpression mod aPowerOfTwo).
• Tests for the ternary operator have been added to chkstr.sd7.
• Tests for the 'element in bitset' operator have been added to chkset.sd7. These tests check the compiler optimizations for SET_ELEM.
• Definitions of HAS_EXPM1 and HAS_LOG1P have been added to cc_conf.s7i.
• Interpreter and compiler have been improved, to support the actions HAS_EXPM1 and HAS_LOG1P.
• In comp/intrange.s7i the function getIntRange() has been improved to consider the actions INT_SUCC, INT_PRED, INT_ICONV1, INT_ICONV3 and SET_RAND. The handling of the actions INT_RAND, INT_ABS and INT_NEGATE has been improved. The functions getIntAddRange() and getSetRandRange() have been added.
• The program chk_all.sd7 has been adjusted to the changes in the check programs.
• A spelling error in s7c.sd7 has been fixed.
• The program wrinum.sd7 has been changed to start with zero.
• Logging functions have been added to reflib.c.... read more
