Practcl is an alternative to critcl. Practcl is designed to be backfit into standard TEA extensions.

Practcl generates blocks of C code and makefile snippets. How those bits fit into the final project are left to the developer.

Implementation:

The practcl system is shipped as a self contained Tcl script. The current version require Tcl8.6. It's inner workings require TclOO.

Example project:

The Odielib project uses pratcl. At the tail end of configure.ac is the following snippet:


======
AC_SUBST(TEA_PLATFORM)
AC_SUBST(TEA_WINDOWINGSYSTEM)
AC_OUTPUT([Makefile pkgIndex.tcl project.rc])
${TCLSH_PROG} ${srcdir}/library.ini
======

The TEA_PLATFORM and TEA_WINDOWINGSYSTEM are computed by the tcl.m4 script, but not normally exported. "project.rc" simply takes in
all of the data that is normally substituted into the Makefile, but stores it in a Tcl friendly format.
