[GLE-announce] GLE 4.2.4c Released

[Announcing G. r. <glx...@li...>]

Dear All,

This is to let you know that GLE 4.2.4c has been released. It is 
available for download from <http://www.gle-graphics.org/>.

Note: this is only a bug fix release. It does not contain the new 
features that are already in the GIT master / trunk repository 
[*].

This release fixes the following issues:
* Added checks on number of data sets, bar definitions, and fill definitions (QGLE crash reports 02/07/2012 and 02/16/2012)
* Save .glerc in user's AppData on Windows
* Added manifest to prevent AUC Virtualization on Windows Vista and above
* Search "C:\Program Files (x86)" on 64 bit Windows for installed software
* Fixed type in manual: logfit -> logefit
* Fixed bug in tokenizer
* Fixed crash when parsing "let d1 = x.x" (QGLE crash report 02/28/2012)
* Fix for message "QWidget::setWindowModified: The window title does not contain a '[*]' placeholder"
* Fixed bug in centering of .inc output (reported by Antonio DiCesare)
* Bug 3485409: GLE should check for Cairo version >= 1.10.0
* Added Python script to generate GLE palette functions (contributed by Brandon Aubie)
* Fixed "too many open files" when including bitmaps in filled boxes (reported by Alexis Letessier)
* Fixed issue with filled boxes (reported by Alexis Letessier)
* Make GLE compile with GCC 4.7.x (issue raised by Terje Rsten)
* Support other 64bit systems besides x86
* Fixed more GLU problems introduced in Qt4.8

Some of these were reported by the QGLE crash reporting feature 
on Windows. Please continue to submit these crash reports. They 
are very useful.

Best Regards,

Jan

[*] I'm referring to these:
* Bitmap caching in the Cairo device (suggested by Alexis Letessier)
* Added "-inverse" option to inverse black / white colors (based on patch by Brandon Aubie)
* Added "percent" number formatting option (patch by Brandon Aubie)
* Added "textcolor" to the key block (patch by Brandon Aubie)

These new features will be included in GLE 4.2.5.

[GLE-announce] GLE 4.2.4b Released

[Announcing G. r. <glx...@li...>]

Dear All,

This is to let you know that GLE 4.2.4b has been released and is 
available for download (source code package and binary installers 
for Windows and Mac OS/X) at:

<http://www.gle-graphics.org/downloads/downloads.html>

The main reason for this bug fix release is that GLE 4.2.4 did 
not compile with Nokia's recent Qt version 4.8 (for example, on 
Fedora 16). Apart from this issue, 4.2.4 also fixes two other 
small bugs.

Changes w.r.t. 4.2.4:

* Added GLU dependency to make GLE compile with Qt4.8 (Bug #3471068)
* Fixed bug in fallback to "texcmr" when using -cairo
* Fixed crash due to subroutine argument type mismatch

Please enjoy this version of GLE.

Best Regards,

Jan

[GLE-announce] GLE 4.2.4 Released

[Announcing G. r. <glx...@li...>]

Dear All,

This is to let you know that GLE 4.2.4 has been released and is 
available for download (source code package and binary installers 
for Windows and Mac OS/X) at:

<http://www.gle-graphics.org/downloads/downloads.html>

The most important new features compared to GLE 4.2.3 are control 
constructs (for-next loops, if-then-else, ...) in graph and key 
blocks, semi-transparent fills and colors (RGBA), the concept of 
layers for graph blocks, and a new CSV data reader.

For details, please consult the change log at:

<http://www.gle-graphics.org/main/changes.html>

Thanks to all who provided feedback on the release candidate!

For those who build GLE from the source code package: a new 
dependency has been added in this release on "poppler-glib".

Please enjoy this version of GLE.

Feel free to share feedback or questions on the GLE discussion 
mailing list.

Best Regards,

Jan

[GLE-announce] GLE 4.2.3b released

[Announcing G. r. <glx...@li...>]

Dear All,

This is to let you know that GLE version 4.2.3b has just been 
released (Windows, Mac, Linux). GLE 4.2.3 contained some 
regressions compared to previous versions because four revisions 
where lost during a code merge. These four revisions, including a 
fix for a crash on a "set font" with an unknown font name, are 
now back in 4.2.3b.

GLE 4.2.3b also contains fixes for some reports that I have 
received from the Windows version. These prove to be very helpful 
in many cases. Please do send them, preferably with the GLE 
script attached to the report. Thanks.

Happy GLEing!

Best Regards,

Jan

[GLE-announce] GLE 4.2.3 released

[Announcing G. r. <glx...@li...>]

Dear All,

GLE 4.2.3 has just been released and is available at:

<http://www.gle-graphics.org>

This is mainly a bug fix release.

For Windows users: this release adds EMF support, which allows 
one to copy and paste vector graphics from GLE to other Windows 
applications such as MS Word. (EMF does not support PostScript 
fonts so one has to use a font such as texcmr.)

For Mac OS users: from now on GLE is also released as a binary 
DMG. This is the first such official release, so please let me 
know if there are problems with it.

GLE's source code has moved from CVS to GIT. Information about 
the new GIT respository is available here:

<http://www.gle-graphics.org/main/git.html>

This is 4.2.3's change log:

<http://www.gle-graphics.org/main/changes.html>

     * #3058793: y1axis dominates the plot (lin/log) bound to y2axis
     * #2782744: Automatic tick labels with latex
     * Fixed compilation on Mac OS/X
     * The graph block's "data" command now understands column c0, which contains the data set's line numbers
     * #2996854: Missing a few multiple bars
     * Fixed: xend()/yend() do not work in QGLE's edit mode
     * QGLE's about box has been improved and shows license and contributors in separate tabs
     * Graph command 'xsubticks length' now overrides 'xaxis grid'
     * Fixed: key block with 'fill' incorrectly changes the 'set fill' value
     * #2995351: Unwanted vertical space generated in graph module
     * Added "background" command to graph block to set the background color
     * #2949503: Fixed a number of errors in the GLE 4.2.2 manual
     * #2950381: Allow "marker m$" with m$ a string variable in the graph block
     * #2949642: Log axis sub tick font size should be based on the "alabelscale" setting
     * #2949495: Access to environment variables: added getenv() command and allow $ENVVAR in file names
     * Added support for single quoted strings
     * Escaping single and double quote characters in strings now works by doubling them
     * Experimental support for EMF output (the vector format on Windows).
     * New QGLE menu entry "Edit | Copy as EMF" to copy the diagram to the clipboard on Windows.

Note that some bugs are still open in the bug tracker.

I hope to give some priority to:
#2949571 I can't use "if" statement in "graph" blocks
#2880795 Error while using "or" in boolean expression
for the next release.

Best Regards,

Jan

[Announcing G. r. <glx...@li...>]

Dear All,

This is to let you know that GLE 4.2.2 has been released. It is 
available from here:

<http://www.gle-graphics.org/>

GLE 4.2.2 is a bugfix release in the 4.2.x series.

Changes:

New Features

     * Additional command line options for GhostScript/PDFLaTeX/LaTeX/DVIPS can now be specified in the "glerc" settings file
     * GLE now expands environment variables in the tool paths specified in the "glerc" settings file.

Bug Fixes

     * QGLE now no longer modifies the string argument of "write" if a text string is moved or one of its properties is changed.
     * GLE now compiles with "-Wl,--no-add-needed" and hopefully also with binutils-gold.
     * Fixed GLE crash on illegal font name.
     * Fixed GLE crash on certain scripts with error bars.
     * Fixed regression in key block in 3.5 compatibility mode.
     * Diamond markers are now also centered in 3.5 emulation mode.

This release adds many improvements to QGLE, among others the 
ability to edit object blocks. It adds support for hierarchically 
named objects and a "compact" mode for the key block. Finally, 
the "let" command's syntax has been extended so that it can 
modify both the x-values and the y-values of a dataset. Below is 
a list of detailed changes.

Enjoy!

New Features
*Added "range" and "nsteps" options to the graph block's let command.
*Added functions file$() and path$() to retrieve the script's name and path (suggested by Jörg Baumgartner).
*Added function isname() that tests if its argument is a named point or object.
*Added "set background" to set background color of shade / grid filling patterns.
*Added "background" to bar command and key block.
*Added "set fillmethod", which can be "GLE" (more accurate) or "PostScript" (faster).
*Source distribution now includes syntax highlighting patterns (in contrib/editors/).
*Source distribution now includes the GLE manual (compile with "make doc").
*Adds "ylabels log n1" to enable subticks without labels on a log scale axis (patch by Luca Donetti).

*Support for multi-dimensional let (#2008719).
*Support for stdin/stdout (#2009125).
*Experimental support for objects with named points.
*Scalable Vector Graphics (SVG) output device (-d svg).
*Engineering format "eng" for the format$ function and axis format option.
*Quantile based axis auto-scaling (by Florian Wisser).
*New axis command: "roundrange on/off" to disable rounding the axis range to the next tick.
*New key block mode: "compact", which combines "marker" and "line" in one column.
*New key block setting: "background", which sets the background color.
*Key box is now transparent (only for keys defined within the graph block).
*Adds function "atan2" (#1881021).
*QGLE is now available on MacOS/X (installation instructions).
*"File | Edit" menu added to QGLE for easy access to files included in GLE script.
*"Edit | Copy as Bitmap" menu added to copy the diagram to the clipboard.
*Adds entries to QGLE's help menu to display the GLE manual and website.
*GUI for detecting GLE's software dependencies (GhostScript and LaTeX).
*Automatically infer device from extension of "-o" option, which specifies the output name.
*DSC comments for title and creator added to PostScript/EPS/PDF output.

Bug Fixes
*Fix for stack corruption in PSGLEDevice::read_psfont() (bug #2543164).
*GLE now creates .inc file if -inc is given and script does not contain TeX expressions (bug #2165591).
*Fix for smooth crash in case of too few data and missing values (reported by Cilliers Kruger).
*Fix for 3D plot bounding box (reported by Brandon Aubie).
*Fix for QGLE compilation on MacOS/X: add "-spec macx-g++" to qmake (suggested by Mol Lukas).
*Fix for "xsubticks lwidth" also affecting the line width of the main ticks.
*Fix for the "strip" target in Makefile.in (by Michal Vyskocil).
*Auto-ranging now also works for x2axis/y2axis (#1933925).
*GLE can't handle filenames with a dot (#2015073).
*Fix for auto-range function with data sets with no spread (suggested by Florian Wisser).
*Fix for "nox" option of "data" command of graph block.
*Fixes for incorrect code points in GLE's Unicode table (o.a., for "ü").
*Combining "clip" + "fill" in "begin path/end path" does not perform the requested fill.

[GLE-announce] GLE 4.0.12 Released

[Announcing G. r. <glx...@li...>]

Dear All,

We have the pleasure to inform you that GLE 4.0.12 has just been released 
and is available here:

<http://www.gle-graphics.org/>

This release introduces QGLE, a previewer and graphical user interface for 
GLE written by A. S. Budden. It includes many improvements to the graph 
and key modules, features scalable LaTeX expressions in GLE scripts, and 
comes with several improvements to the GLE scripting language. A detailed 
list can be found below.

Changes in 4.0.12

*  Includes a GUI called QGLE
   - displays the output of GLE and updates automatically after the source
     file is modified (run "gle -p myfile.gle")
   - has basic editing tools (add amove/line/circle/...)
   - QGLE is based on the QT and Ghostscript library
* Added GNU autoconf support (in addition to the regular makefile.os system)
   (on Linux, one can now compile with ./configure; make; make install)
* Added autopackage support
* UTF8 support (limited to latin characters with accents)
* LaTeX expressions are scaled to the current font height
   (set texscale none/fixed/scale)
* LaTeX expressions are used in key and graph blocks (set texlabels 1)
* The "begin box / end box" block now fills underneath its contents
* Added keyword "local" to define local variables
   (see e.g., Examples | Fractals | Sierpinski on the website)
* Added "colormap" command (regular and graph block)
   (see e.g., Examples | 3D plots | Information Gain on the website)
* Colormap works for functions and for .z files
* Added option "-v" to run another version of GLE
   (if more than one version is installed, use "gle -help v" to list installed
    versions)
* Added "begin object name" and "end object" to define objects
* Added "draw name.pos" to draw objects
* More sensible defaults for graph font sizes
   (use gle -cmode 3.0 to get the old defaults)
* Font size in graph now depends on the "hei" setting
* Added new set subcommands: titlescale, atitlescale, ticksscale,
   atitledist, alabeldist (to set font sizes and distances relative to the
   value of the "hei" setting)
* Distance between axis labels and title are better calculated
* Added "margins", "dist", "coldist" and "row" options to key block
* Added "scale h v" command to graph block, which is equivalent to
   a hscale/vscale pair
* Added colored fill patterns for the "bar" command and key block

   bar d1,d2,d3,d4 fill blue,red,blue,purple pattern none,shade,grid,shade2

* Added "xnames from di" to retrieve the axis labels from a data set
* Added "xnoticks p1 p2 ..." to disable ticks at specified positions
* Added "ftick x0" to "axis" to manually set the position of the first tick
* Added "offset y0" to "axis" to move the origin of the axis
* Added "angle a" to "axis" to rotate the axis labels
* Added "x0axis" and "y0axis" (these are disabled by default)
* Added option "center" to center a graph block
* Added option "math" to create a "math mode" graph with the axis crossing
   at the origin (see e.g., Examples | 2D Simple | Sin on the website)
* Added option "horiz" to bar command allowing "horizontal" bar plots
* Added option "style" to bar command allowing user defined bar styles
   (see e.g., Examples | 2D Complex | Color Bar on the website)
* Added arrow styles "filled", "empty" and "simple"
* Added support for user defined arrow styles
   (see e.g., Examples | Other | Arrow Styles on the website)
* Added function xbar(xp,i) retrieving the x-coordinate of bar i in a bar plot
* Added function xy2angle(dx,dy) that computes the angle (polar coords)
   given dx and dy
* Added function sdiv(x,y) implementing y == 0.0 ? 0.0 : x / y
* Added formatting modes "pi" and "frac" to format$
   (see e.g., Examples | 2D Simple | Sin on the website)
* Subroutine definitions and assignments can come before the size command
* Checks for correct nesting of all block commands
* While loops are now also supported (besides until ... next loops)
* Support for single line then/else blocks allowing code such as

   if a < 1 then print a "is smaller than 1"
   else if a < 2 then print a "is smaller than 2 but larger than 1"
   else if a < 3 then print a "is smaller than 3 but larger than 2"
   else print a "is larger than 3"

* LaTeX expressions can now also be used in combination with .ps output
* Axis scales are now computed based on the datasets that are actually used
* Graph block can include function calls, of which the output is clipped to
   the graph window (see e.g., Examples | 2D Complex | Labeled Scatter on
   the website)
* The manip utility has been integrated back into the GLE distribution
   (see e.g., this screenshot of manip).

We hope that you all enjoy it!

We would like to thank everyone that helped testing the release candidates 
of 4.0.12. Thank you all for the helpful comments and suggestions!

The GLE development team.
