How to syntax-highlight a fish command?

[JanPokorny]

I use fzf for CTRL+R. It's really nice. But it does not support syntax highlighting, and I like syntax highlighting, so I decided to hack it together.

How does fish do the syntax highlighting, though? Is there a builtin command that will take a string and highlight it? I know I could use bat -l fish, but it uses a different color palette and is an external program. I would prefer to just let fish highlight the command, if there is a way to programatically call the highlighter.

fish_indent --ansi will highlight any command you give it via stdin. It is a real binary on your system. It will indent all the input as well, use --no-indent to suppress that (it will still reformat to one job per line tho).

Or you could update to fish 3.6 and try the new builtin history pager, which highlights automatically.

The pager does fuzzy matching - as in "find these characters in that order, but possibly with things in-between" - ecfrd will find echo fus roh dah

@faho That does not seem to work for me:

It only does an exact match:

I seem to be using the latest Fish (from Homebrew):

Aaah, yeah that's #9476, coming in the next release.

BTW, is it possible to invoke this new pager programatically? (Like with fzf, for example with a custom list of folders from zoxide?)

[faho]

No. That's #2805.
