Best way to highlight json logs

[Tony-Sol]

I use bat --paging=never -l log to highlight logs output from docker containers, and have log record as valid json struct.
Is there a best way to combine language arguments, which would say that all stdin stream should be processed like -l log and lines from stream like -l json?

This isn't really possible without editing the syntax definition, which is basically just a YAML file with regex patterns. https://github.com/sharkdp/bat/blob/master/assets/syntaxes/02_Extra/log.sublime-syntax.

Likely you'd want to add a new - match to the main_without_log_level_line context to look for { and embed the JSON syntax and pop at EOL.
You should be able to experiment by copying the log.sublime-syntax file to your bat config folder and following the instructions https://github.com/sharkdp/bat/tree/master#adding-new-syntaxes--language-definitions

If you can share some example log lines, I might be able to spare some time to work on it at some point.

Well, it turned out that in my case the problem is different - vscode theme has same color for json string values and object keys.
Using other theme, like TwoDark, makes output colorized exactly as i need

Ah nice, thanks for sharing and glad you got it working the way you want 🙂 probably I should update the highlighted test file for the log syntax to include some JSON like that, then I might have spotted it myself 😉
