I've been trying out elm-watch and it has been working great so far.
I did encounter a curious problem. We have 99 target inputs and when running hot mode I got a 'The command line is too long.' error. This is the full error:
-- UNEXPECTED ELM OUTPUT ----------------------------------------------------------------------------------------------------------------------------
Target: Widgets
I ran the following commands:
cd 'C:\Users\harm\Dev\Symbaloo\main\symbaloo-web\frontend'

I expected it to either exit 0 with no output (success),
or exit 1 with JSON on stderr (compile errors).
But it exited like this:
exit 1
The command line is too long.
71 errors found

I believe the max line length for command line on Windows is 8191 characters. When I reduced the number of targets at some point the error disappeared.
After some digging I found out that this only happens when running elm-watch hot inside a yarn/npm script. When you run elm-watch hot directly from the command line it is not a problem.
- ✅
elm-watch hot - ✅
node myscript.js->elmWatch(["hot"]) - ❌
npx/yarn elm-watch hot - ❌
npm/yarn run my-script->elm-watch hot - ❌
npm/yarn run my-script->node myscript.js->elmWatch(["hot"])
I'm not sure if this is actually an elm-watch issue. But it's quite inconvenient if you can not use npm/yarn to run elm-watch.
One thing that would help might be to use relative paths in the elm make command above. That would shorten the command line a lot and make it less likely that this issue occurs.
Tested on Windows command line with version 1.1.2 and 2.0.0-beta.2.
