Using a `pnpm:` shortcut with a wildcard (*) does not work with JSON5 (package.json5)

[mark-monteiro]

pnmp supports using package.json5 instead of the regular package.json, which is super useful to be able to add comments in the package file.

Concurrently allows specifying a shortcut command with a * wildcard like concurrently "pnpm:lint:*", which would run all scripts in package.json that start with lint:.

This all works well when running with package.json, but when using packages.json5, it results in the following error:

$ pnpm test

> example-project@ test C:\.......\example-project
> concurrently --group pnpm:test:*

 ELIFECYCLE  Test failed. See above for more details.

This error occurs even if the file contents have not changed at all (i.e. still valid regular JSON) and only the file has been renamed to .json5

Thanks for the report, this is easy to reproduce and it has to do with package.json not existing. Weird that it's a silent exit though.

A bit more research on this:

pnpm supports alternative package.json formats. For these to work, we need the relevant parsers - JSON5 and YAML. The flagship packages on npm are large, 235 KB and 405 KB respectively.
It's not very fair to make every concurrently user download these, so I won't be adding them as dependencies yet.

A JSON5 parser can probably be hand-implemented somewhat easily though, so I might look into that.
But I'm not into feeling like implementing a wildly different syntax such as YAML yet 😄
