psa
A pretty, flexible error/warning reporting frontend for the PureScript compiler
(psc).
- Colors!
- Original source spans in errors
- Fine-grained warning filtering
- Warning persistence
Install
npm install -g purescript-psa
Sample Usage
Censor all warnings:
psa --censor-warnings <psc-options>
Censor library warnings:
psa --censor-lib <psc-options>
Censor source warnings:
psa --censor-src <psc-options>
Censor specific warning codes:
psa --censor-codes=ShadowedName,ImplicitImport,MissingTypeDeclaration <psc-options>
Only show specific warning codes:
psa --filter-codes=DeprecatedOperatorDecl,DeprecatedClassExport <psc-options>
Turn source warnings into errors:
psa --strict <psc-options>
Note: It's assumed psc is in your path. If you'd like to use a custom
binary location you can set the --psc=/foo/bar/psc flag.
Persisting Warnings
psc does not persist warnings between compilations, but psa can do it with
the --stash flag. This serializes the set of warnings to disk and merges it
with the new set on each compilation.
psa --stash <psc-options>
If you are compiling multiple projects from the same root, you can specify which stash file should be used:
psa --stash=.foo-stash <psc-options>
Usage with pulp
Pulp supports building with psa: it will be used by default if it is installed, and options will be passed through, eg:
pulp build -- --stash --censor-lib <psc-options>
