Allow customizing the location of `TLDR_HOME`

[Seirdy]

Currently, TLDR_HOME is hard-coded in src/tldr.h to point to ~/.tldrc.

It would be nice to configure this location via environment variables or a config file. I personally would prefer to set TLDR_HOME to $XDG_DATA_HOME/tldr to comply with the XDG Base Directory Specification and keep my $HOME clean.

Please make this happen!

Hi there, I think it should be $XDG_CACHE_HOME/tldr instead of $XDG_DATA_HOME/tldr. The "manpages" contained there are cache that can be recreated.

Backup systems will typically ignore the $XDG_CACHE_HOME/ (which defaults to ~/.cache/ if undefined), but not $XDG_DATA_HOME/, as the later should contain user data. Cheers!

If this feature is ever implemented, this change should also be made to the shell completions in the autocomplete/ directory, as right now they are hard coded to $HOME/.tldrc/tldr/pages/.

Hi there! Was this finally implemented? I think the bot closed as stale (I don't see a related merge PR or similar).

For anyone interested there's a very performant Rust implementation of tldr that implements Freedesktop.org XDG spec: tealdeer https://github.com/dbrgn/tealdeer
Can be installed with Brew, Nix,...
