Meta: Feature Requests

[evancz]

Do not reply directly to this issue. It will be deleted. This is just for aggregating what everyone wants so we can try to address it all in a coherent way.

I have tried to categorize feature requests to see what kinds of things folks are interested in, so I can prioritize work appropriately.

Warnings

• Report warnings as errors #108 - option for --warn to be treated as errors
• Turn on '--warn' flag as a default. #141 - turn on --warn by default
• No "unused function" warnings #137 - warn for unused functions
• --warn about unused variables #181 - warn for unused variables
• No "unused function argument" warning #153 - warn for unused arguments
• --warn should warn about unused functions exposed from import #158 - warn for import X exposing (unused)
• Feature request: --warn-ignore flag for ignoring certain files when using --warn #173 - no warnings for specific files

Editor Stuff

• Coherent format for --report=json #47, Errors from header-parse phase do not get put in --report=json #118 - coherent format for --report=json
• Warnings are only reported when the module is compiled #27 - always spit out all warnings with --report=json
• add option/switch for "color markers" in json output #73 - let editor folks get color markers in types and such
• Add support for filename and line number in json docs #29 - add file name and line number in documentation.json for jump to definition
• Add author, name and version to documentation.json #149 - add README, package name, version to documentation.json
• Generate docs for subpackages #28 - make it easier to get docs for dependencies

Automated Testing

• Add --only-dependencies #84 - caching of built files on a machine to make things faster

Better Semver Reliability

• Disallow exposing (..) in exposed modules for semver guarantees #61 - no open imports in packages, avoid name collisions due to adding names to subpackages
