Thanks Aditya.
What do you think of changing the default luatex-cache directory to the
system's temporary directory? Consider:
- The $HOME directory is sacrosanct (4784 people agree:
https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1575053)
- The temp directory is cleared on Linux (Unix?) system reboots; purged
during regular Windows upkeep
- The temp directory is writable by default
- Changing the location requires calling an additional program, which
isn't obvious (principle of least astonishment)
My text editor invokes ConTeXt like:
if( TYPESETTER.canRun() ) {
env.put( "TEXMFCACHE", System.getProperty( "java.io.tmpdir" ) );
mArgs.add( TYPESETTER.getName() );
mArgs.add( .. --path .. --purge .. --batch .. --result ..
--environment .. etc. );
mArgs.add( inputFilename );
}
The first line ensures that "context" is an executable located in a PATH
directory. The second line attempts to change the luatex-cache directory.
The remaining lines configure the command-line arguments prior to running
ConTeXt.
Fearing flaming wrath from users, an additional mtxrun call is required,
which incurs overhead:
- Check for mtxrun executable
- Run mtxrun each time
This would work but feels like a leaky abstraction (i.e., the context
executable should honour TEXMFCACHE without needing to invoke mtxrun
because context creates the luatex-cache directory).
Thoughts?
