Some *.conf files not highlighted

[eggbean]

I wanted to add syntax highlighting for for .tmux.conf file, so I add this file to bat/syntaxes/

https://raw.githubusercontent.com/gerardroche/sublime-tmux/master/Tmux.sublime-syntax

I then bat cache -b and try viewing my .tmux.conf file, but it is still plain with no syntax highlighting. Have I missed something or does this file not work with bat for some reason? Tmux and the file extensions do appear with bat -L.

I just realised that it works when I force it like this:

$ bat -l Tmux .tmux.conf

So why is it not detecting the file when it is named in the same way that the bat -L mentions?

ie.

Tmux tmux.conf, tmux, .tmux.conf, .tmux

@keith-hall After reading that I noticed that /etc/resolv.conf was not syntax-highlighted either. I upgraded from 0.17.1 to 0.18.1, rebuilt the cache and now /etc/resolv.conf is coloured, but tmux.conf is still not, unless that I specify with --language.

I think this might be due to this explicit syntax mapping to "unknown":

bat/src/syntax_mapping.rs

Lines 54 to 58 in 42f1ef0

	// Nginx and Apache syntax files both want to style all ".conf" files
	// see #1131 and #1137
	mapping
	.insert("*.conf", MappingTarget::MapToUnknown)
	.unwrap();

I think you could fix it locally by adding:

--map-syntax tmux.conf:Tmux

to your config file.

But that still leaves the question if this should be fixed somehow...

Thanks, I've added that line to my config for the time being.

I can take a look at this issue.

👋🏻 I've just installed bat version 0.19.0 and I still find tmux.conf files are plaintext.

I tried bat --map-syntax tmux.conf:Tmux but it didn't work (bat just hung) and so looking at bat --list-languages I realised I don't see Tmux in the list.

Is there anything in particular I need to do to get support for tmux.conf ?

Thanks!

@Integralist If it's not part of bat, add the file I linked to in the top comment to your ~/.config/bat/syntaxes directory and rebuild the cache with bat cache --build.

@eggbean ah! nice OK I see. Thank you that works great 🙂
