Hi all,

I won't attend the call, sorry.

That said let me take this opportunity to inform everybody I have 
created a repository called 'rtext' which is a first embryonic attempt 
at providing the revised text widget as a TEA package. See:

https://chiselapp.com/user/fvogel/repository/rtext

Current state is that it builds for Windows, but there is nothing more 
at all. It does not build on Linux or mac. On any platform, the tests do 
not run, the man page does not get built, and so on.

The next thing to solve is that it crashes during revised text widget 
instantiation because tkStubsPtr is NULL. I know nothing about stubs so 
far, and would be happy to get some help here. Thanks.

If you want to check this out on Windows, please see recipe pasted below.

The big advantage of this TEA approach is that one should be able to 
have both the legacy and the revised versions of the text widget at the 
same time. And it saves us from making the terrible decision to replace 
the legacy widget by the revised version in the distributed Tk.

As I said, this is *very* embryonic --> Don't expect anything at this 
stage. Help to push this forward is very welcome.

Regards,

Francois

---------------------

My build recipe for Windows with Visual Studio (please adapt as needed):

REM Tcl /Tk 9 must have been built and installed first. REM Tcl 9 and Tk 
9 source code directories set 
MYTCL="C:\Users\francois\Documents\Development\tcltk-fossil\tcl" set 
MYTK="C:\Users\francois\Documents\Development\tcltk-fossil\tk" REM 
Tcl/Tk 9 installation directory set 
MYTCLTK="C:\Users\francois\Documents\Development\tcltk-fossil\tcltk" set 
DEBUGRELEASE="symbols" CALL "C:\Program Files\Microsoft Visual 
Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat" x86_amd64 cd 
C:\Users\francois\Documents\Development\tcltk-fossil\rtext\win nmake -f 
makefile.vc TCLDIR=%MYTCL% TKDIR=%MYTK% INSTALLDIR=%MYTCLTK% 
OPTS=%DEBUGRELEASE% clean nmake -f makefile.vc TCLDIR=%MYTCL% 
TKDIR=%MYTK% INSTALLDIR=%MYTCLTK% OPTS=%DEBUGRELEASE% nmake -f 
makefile.vc TCLDIR=%MYTCL% TKDIR=%MYTK% INSTALLDIR=%MYTCLTK% 
OPTS=%DEBUGRELEASE% install

Then fire tclsh90.exe and run:

     package require Tk
     package require rtext
     rtext::build-info
     ::tk::text .lt    ; # legacy
     text .rt          ; # revised (crashes at this stage)
