0.22.0

Highlights

Parse Incomplete Text

Ever been annoyed by not being able to navigate or hover for docs functions simply because your function is not complete and therefore it does not parse? @gomoripeti improved the way Points of Interest are extracted from the code, so that's no longer the case!

Improved Support for Variables

Thanks to @plux Erlang LS can now identify the scope of a variable in a more consistent and reliable way. Among the new improvements:

• Improve the identification of variable scopes within functions
• Add possibility to rename variables within -spec
• Fix parsing of variables within macros
• Add support for navigating variables outside of functions
• Add support for finding variable references

Rename Functions While Standing on -spec

It was already possible to rename a function via Erlang LS (which would update all references to it). For extra convenience, it is now possible to trigger the rename operation from a -spec, too!

Global Config

maps:merge(Global, Local)

Erlang LS offers the possibility to specify a system-wide erlang-ls.config. Until now, a local configuration for a project would override the global one entirely. Erlang LS now combines the two configuration, for a hopefully more natural development experience.

Module Name Check

In Erlang, the name of a module, expressed in a module attribute has to coincide with the filename minus the extension to ensure code loading works smoothly.

A new diagnostic is now emitted when this is not the case, informing the user. The next natural step is to add a quick action to quickly fix this. Why not to implement this as your first Erlang LS contribution? We are happy to help in getting started on how to become a contributor!

Debug Logs

erlang_ls -l debug

Due to a bug, it was not possible to correctly visualize debug logs. Thanks to @AminArria this bug is finally fixed, so happy troubleshooting!
