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).

Thanks Aditya.

<= div>What do you think of changing the default luatex-cache directory to the= system's temporary directory? Consider:
  • The $HOME di= rectory is sacrosanct (4784 people agree: https://bugs.launchpad.net/ubuntu/+= source/snapd/+bug/1575053)
  • The temp directory is cleared on Lin= ux (Unix?) system reboots; purged during regular Windows upkeep
    • The temp directory is writable by default
  • Changing the location re= quires calling an additional program, which isn't obvious (principle of= least astonishment)
My text editor invokes ConTeXt like:
=
=C2=A0 =C2=A0 if( TYPESETTER.canRun() ) {
=C2=A0 =C2=A0 =C2=A0 env.p= ut( "TEXMFCACHE", System.getProperty( "java.io.tmpdir" = ) );

=C2=A0 =C2=A0 =C2=A0 mArgs.add( TYPESETTER.getName() );
=C2= =A0 =C2=A0 =C2=A0 mArgs.add( .. --path .. --purge .. --batch .. --result ..= --environment .. etc. );
=C2=A0 =C2=A0 =C2=A0 mArgs.add( inputFilename = );
=C2=A0=C2=A0=C2=A0 }

The first li= ne ensures that "context" is an executable located in a PATH dire= ctory. The second line attempts to change the luatex-cache directory. The r= emaining lines configure the command-line arguments prior to running ConTeX= t.

Fearing flaming wrath from users, an additional= mtxrun call is required, which incurs overhead:
  • Check fo= r mtxrun executable
  • Run mtxrun each time
This wou= ld work but feels like a leaky abstraction (i.e., the context executable sh= ould honour TEXMFCACHE without needing to invoke mtxrun because context cre= ates the luatex-cache directory).

Thoughts?
