Abstract
The Tk demos can be installed anywhere but this location is not recorded anywhere. This TIP proposes recording the demo directory location.
Rationale
The Tk demos can be installed in a non-default directory
by overriding the Makefile variable DEMO_INSTALL_DIR
at install-time.
Since this information isn't recorded anywhere
there is no practical way for an external entity
to determine the demo install directory.
Proposal
Add an overridable configure-time variable
DEMO_DIR
that by default contains the current default demo install directory and have this propagate through the build system.Record the configured demo directory in tkConfig.sh, tk.pc and
::tk::pkgconfig
.
Platform Considerations
- Unix, MacOSX
- This TIP works as described.
- Windows
- This TIP works as described however saved configuration information about directories is generally less useful on Windows because Tk is almost never installed into the same directories that are recorded in the pre-built files.
Current Uncertainties as of 2017/11/21:
- The function GetWidgetDemoPath in macosx/tkMacOSXMenus.c uses a different method to retrieve the value of the widget demo path. Is this ok?
- Only tested on Unix.
Reference Implementation
The reference implementation is available in the tk-stu-pkg branch. https://core.tcl-lang.org/tk/timeline?r=tk-stu-pkg
The code is licensed under the same license as Tk.
