Cann't get syntax highlighting to work

[o01eg]

I have installed xi-core and xi-term in /usr/bin, and syntect in /usr/share/xi/plugins/.

When I open file in xi-term I didn't get syntax highlight.

xi-term.log

xi-term.rpc.log

xi-core.log

Looks like it should set client_extras_dir parameter for client_started message.

[o01eg]

What if use option_env! to allow set this value?

[msirringhaus]

I have it under $HOME/.config/xi/plugins/, there it works.

[o01eg]

It is not useful for system-wide installation or noexec on home folder.

[msirringhaus]

Have you tried setting the approriate XDG environment variables?
I think xi-term and xi-core are using those.

[o01eg]

I suppose those variables don't intended to point to read-only folders.

[msirringhaus]

Ok, think you are right about client_extras_dir, which needs to be set.
Question is, is there a sensible mapping to XDG? XDG_DATA_DIRS are per default under /usr/ (which usually is read only for normal users) and extra_dirs is supposed to be

An optional client-provided path for bundled resources, such
as plugins and themes.

So this might be a good fit?

[o01eg]

Looks reasonable, but XDG_DATA_DIRS is a multiple dirs. Could xi-core changed to accept multiple dirs in client_extras_dir or so parameter?

[msirringhaus]

Hm, either that or xi-term goes over $XDG_DATA_HOME:$XDG_DATA_DIRS one by one and checks if a xi/-subdirectory exists. If so, it takes it and sends it along. This would of course always take the first hit and ignore the others.

/usr/share/xi/plugins/

That doesn't seem like the right location though, share usually is meant for arch independent stuff (icons, themes etc.), while binaries (like the plugins) should be in lib or libexec. Anyway,
