Porting extensions to Tcl 9

PO - 2023-04-05

This page is the summary of my experiences trying to port the Tcl packages or programs supported by BAWT to Tcl 9.

The versions used for the tests were Tcl 9.0b1 (a97f381771) and Tk 8.7b1 (002da37d).

Note, that all changes listed below regarding size_t must be replaced with either ptrdiff_t or Tcl_Size, if TIP 660 will be accepted, which I strongly encourage.

Table Packages lists all packages looked at and their current status. Tables Changes in Tcl and Changes in C summarize all changes done at the Tcl and C level for all packages. All other tables summarize the changes done for each individual package or program.

Please feel free to add your experiences, additions and comments.

Packages

This table summarizes the status of the package ports.

The columns show the folllowing information:

Library: The name and a link to the package home page.
Tcl8 Version: The version number and a link to the source of the package as used in BAWT for Tcl 8.6.
Tcl9 Version: The version number and a link to the source of the modified package. If no entry is given, then either the Tcl8 version is working or I did not look at the package or it was too much effort.
Build: The modified package could be compiled with Tcl 9.
Require: A package require suceeded for the package with Tcl 9.
Bawt Test: The simple BAWT test program for this package works with Tcl 9.
Module Tests: I did not perform any package module tests right now.
Responsible: Add a link, if you are the maintainer or feel responsible for this package.
Comments: Short comments regarding this package. Add longer comments at the end of the table.
