How to define default theme in system-wide configuration files ?

[vincesdf]

Hi,

I want to create an RPM file to deploy my custom format and theme files, and also configure lnav to use my custom theme for all users.

I install my format and theme files in /etc/lnav, but I haven't found how to set the default theme for all users.

I can iterate over each user and run the following command, but it's not a very elegant solution:
lnav -n -c ":config /ui/theme custom_theme" -c ":quit"

Any ideas?

Thanks

You can create a file with your desired config, like:

{
  "ui": {
    "theme": "custom_theme"
  }
}

Use lnav -h to check where format files are read from on your system (look under the "Paths" section). For example, if /etc/lnav is listed, you can put the above contents in a file named /etc/lnav/formats/local/config.theme.json. lnav should then pick it up. Use lnav -d /tmp/lnav.dbg to turn on debug logging and check that file if you are having issues.

Why should theme configuration be placed in subdirectory of formats directory and not config?
Theme feels like part of configuration not formats' definitions.

It works like a charm, Thanks @tstack !

Putting it under configs would work as well. Keeping configuration and format files can be convenient in other cases, though. Like, where you just want to have a single git repo that is shared with a bunch of folks.

I don't see any information that lnav searches for configuration in the formats directory at https://docs.lnav.org/en/v0.12.0/config.html
I think this should be added there with the information on the priority between configurations placed in configs and formats directories.
