Build error(maybe psc-package related)

[RAbraham]

Hi, This may very well be due to a lack of understanding of how psc-package works but I'm getting a build error while trying to build in vscode from a psc-package created personal project

Details:

• PureScript version: 0.11.3

Steps:

• Create a project directory and cd
• psc-package init and psc-package build
• Open project directory in vscode
• vscode displays Started psc-ide-server (port 15206) message
• Open my simple file(src/Trial.purs)
• Press Cmd+Shift+B

Result: Shows Error message Build Error. I don't see any specific errors being reported in the bottom status ribbon.

How did you configure your build command? By default the command is something like pulp build -- --json-errors, but pulp doesn't yet support psc-package.

You can set a custom build command but as the config doesn't support shell syntax, you may want to use a wrapper script.

(If you build externally then rely on rebuild on save, things should be fine with psc-package, but you will need to configure appropriate file globs if you want goto-definition)

my bad, I should have mentioned that I'm not using pulp. I tried updating my settings.json with the following addition:

"[purescript]": {
            "purescript.buildCommand": "psc-package build"
    }

psc-package is in my path. But when I build, I get the following warning:

file: 'file:///../settings.json'
severity: 'Warning'
message: 'Unknown Identifier. Use language identifiers'

Try not nesting under [purescript], I think that is just for editor settings. At least I only see autocomplete in settings.json for purescript.blah at the top level

Unnesting worked +1. But I could have misinterpreted your suggestion but "purescript.buildCommand": "psc-package build" should have worked?

Also you'll need to run a build command that runs psc with --json-errors flag, if you want to get error results, I don't think psc-package can do this. Otherwise you can run purs compile with some globs directly, or wrap in a script which uses psc-package sources to get the correct globs to pass in.

But again, mostly the rebuild on save which uses purs ide server directly
