Restricting helm and ag to certain files

ag is great and searches through your code base in the blink of an eye. Coupled with helm it makes for a great experience finding things. If run in a git project then it helpfully ignores those in your .gitignore file.

However, in most projects I have files with different extensions, maybe some .md for documentation, some .html for published documentation, .clj, .cljs, .cljc, .js etc. I often know in which files the thing I am searching for lives, but I hadn’t figured out a way to restrict ag.

That isn’t quite right - you can restrict ag at the command line with -G<backslash>.<ext> so ag -G<backslash>.cljs DEBT will find the (unfortunately many) instances of code that I consider technical debt.

Unfortunately I can’t figure out how to escape the backslash (\\) in code blocks so the literal text is “ag -G\\.cljs”_

This works great, but in spacemacs these sorts of configuration switches are typically mapped to keys.

Reading the really useful spacemacs FAQ tells you that what you type in the helm input is passed straight through to ag.

So, next time I need to feel depressed I can search (SPC s p) for “DEBT” or, if I only want to feel generally low then I can search for -G<backslash>.clj DEBT :-)

Have a great day all.
