taotieren created merge request #2 on Code
Supports Tcl version 8.6.10 and above detection
-
Update bool using c23 specification
-
Sergei Golovan posted a comment on ticket #46
Hi! My patch seems to be incomplete. The way it is, including blt.h withou prior tcl.h leads to compile errors because Tcl_AppInitProc is undefined. This will break configure scripts which try to find blt.h by compiling simple files with #include <blt.h> in them. Here is one possible fix - included tcl.h inside blt.h.</blt.h>
-
A few fixes and changes in blt::vector
-
Blt_TclInit() and Blt_TkInit() are declared only if USE_BLT_STUBS is defined

tabset uses wrong padding for windows in its tabs

tabset closes tab when it loses its window
-
Typos in bltParseargs.c
-
Fix segfault in the htext widget

I'm sorry, the second patch is incomplete. It misses adding the two functions to the bltTkProcs structure. Here is the corrected patch.
-
Compliling fails using GCC-15
-
Typos in the documentation

Edward Sternin posted a comment on a wiki page
Oh, I see! Vectors get created even without create! This might be good enough. I'm not 100% clear as to why syntactical compatibility between 2.x and 3.x is needed. Nor why the vectors need to created in a single command. Is this because the TCL code making the call can't be changed? The reason for my initiating this compatibility discussion is this: if I want to write a code that I can distribute (to students, for example) I need to anticipate the environment in which they will be using it. The...

I think it was me that was probably unclear. If you don't use the "create" keyword, then you can still create multiple vectors with the same command. This works in both 2.x and 3.x. bltsh30 % blt::vector x(30) y(30) z(30) I'm not 100% clear as to why syntactical compatibility between 2.x and 3.x is needed. Nor why the vectors need to created in a single command. Is this because the TCL code making the call can't be changed? [It wasn't my goal in 3.x to be 100% backward compatible with 2.x syntax....
-
Sorry, @ghowlett, I may have been unclear. It's the loss of ability to declare multiple vectors on one line that represents a discontinuity in syntax: $ bltsh30 % blt::vector create x(5) t w unknown switch "t" The following switches are available: -variable varName -command command -watchunset bool -flush bool -length length although I just noticed that there is in v.2.5.3 from blt-dev an option: vector configure -oldcreate bool which may be doing what I had in mind: The configure operation sets...
-
I believe the syntax blt::vector /arrayName/(/len/) works the same in both versions. Since the create operation has switches in 3.x, the old syntax of blt::vector create /arrayName/(/len/) ... * * could not be cleanly maintained. [The idea in 2.x was to have the vector look like a data type instead of a command.] ** You would still have to set the values to 0.0 to replicate the 2.x behavior. --gah On 7/6/22 18:27, Edward Sternin wrote: BLT v.3 significantly changed the syntax of the |vector| command....

postscript BB is off

Very simple but useful things that are missing in v.2.x : [x min] and [x max]. This is difficult to overcome (my shortest version is x dup xx; xx sort; puts "$xx(0)" for min), and the best workaround I found is to use critcl: package require BLT namespace import ::blt::* package require critcl critcl::clibraries -lBLT critcl::ccode { #include <tcl.h> #include <blt.h> } critcl::cproc minValue { Tcl_Interp* ip Tcl_Obj* v } double { Blt_Vector *vp; Blt_GetVector(ip, Tcl_GetString(v), &vp); return vp->min;...

BLT v.3 significantly changed the syntax of the vector command. Since a lot of places are still running v.2.47z, trying to write universal code requires accommodations like these: proc newVector { name len } { # BLT 2.x allowed to re-create existing vectors, # this is necessary in BLT 3 but will also work in BLT 2.x global BLT3 $name if { [info exists ${name}] } { vector destroy ${name} } if {$len != "" && $len > 0} { if {$BLT3} { vector create ${name} -length $len # BLT 3 initializes to NaN, restore...

I agree that the behavior should be the same as TCL. I'll make the changes. --gah On 7/5/22 13:17, Edward Sternin wrote: [bugs:#159] https://sourceforge.net/p/blt/bugs/159/ unnecessary and harmful underflow error in vector Status: open Group: Created: Tue Jul 05, 2022 06:17 PM UTC by Edward Sternin Last Updated: Tue Jul 05, 2022 06:17 PM UTC Owner: nobody In |bltVecMath.c| the test for underflow in vector |expr| calculations produces unexpected behaviour, an error "floating-point value too small...

Just updated the code from this site, compiled and verified that the same behaviour is seen in the current version (3.0? 4.0?) of BLT: $ blt-src/src/bltsh30 fpbug.tcl tclsh underflow with y = exp(-x**2) 25.00 --> 3.681e-272 26.00 --> 2.612e-294 27.00 --> 2.508e-317 28.00 --> 0.000e+00 29.00 --> 0.000e+00 30.00 --> 0.000e+00 blt underflow with y = exp(-x^2) 25.0 26.0 27.0 --> 3.6808558548018004e-272 2.6117417612840555e-294 2.507972e-317 25.0 26.0 27.0 28.0 --> floating-point value too small to represent...
