Regex with inotifywait to compile two types of file in golang

Question

I use a script to auto-compile in golang with inotifywait. But this script only checks files with the extension .go. I want to also add the .tmpl extension but the script uses regular expressions. What kind of changes I have to make to this line to get the desired result?

inotifywait -q -m -r -e close_write -e moved_to --exclude '[^g][^o]$' $1

I've tried to concatenate with | or & and other things like ([^t][^m][^p][^l]|[^g][^o])$ but nothing seems to work.

Does the above work with `file.ao` or `file.ga`? I doubt it. — Wiktor Stribiżew, Jan 08 '16 at 10:57
@stribizhev i've tried in https://regex101.com/ and it worked — CondeGil, Jan 08 '16 at 11:21
`.ao` and `.ga` are [not matched](https://regex101.com/r/hZ4tJ7/1). If that is what you need, then OK. — Wiktor Stribiżew, Jan 08 '16 at 11:22
@stribizhev is exactly that what I need. Try this list (width /gm): .go .og .ao .ga .got .ext .properties main.a — CondeGil, Jan 08 '16 at 11:25
You seem to have used a zero instead of `o` in `([^t][^m][^s][^l]|[^g][^0])$` (and also `s` instead of `p`). — Wiktor Stribiżew, Jan 08 '16 at 11:31
@stribizhev I have not used a 0, the error was when I wrote here — CondeGil, Jan 08 '16 at 11:33

Rather than trying to use a regex to exclude two types of file, why don't you just only watch those files?

inotifywait -q -m -r -e close_write -e moved_to /path/**/*.{go,tmpl}

To use the ** (which does a recursive match), you may have to enable bash's globstar:

shopt -s globstar
