ALE Files

Special Notes

• The pyls linter has been removed because it's no longer maintained, and it has been replaced with the pylsp linter. [#3810]
• The dartanalyzer linter has been removed because the Dart team discourages its use over built-in tools instead.

Deprecated Features

• The ale_lsp_root setting is now deprecated, and you should replace it with ale_root instead. [#3599]

New Features

• :ALEGoToTypeDefinition is now supported for tsserver. [#3545]
• You can now rename TypeScript files with the :ALEFileRename command. [#4012]
• You can now manually populate loclist and quickfix with :ALEPopulateLocList and :ALEPopulateQuickfix, respectively. [#3761]
• You can now send found references to quickfix with :ALEFindReferences -quickfix. [#4033]
• Linters and fixers can now set their cwd separately from their commands to run them, to make them easier to manager and enable other features. [#2281]
• ALE will now read signs with sign_getplaced, when the function is available. This is faster and safer. [#3648]
• When repeating selections, ALE will now jump to the last selected item, such as when finding references.
• ALE will now de-duplicate items before adding them to the location list. [#3792]
• Popup windows are now supported in Vim versions that have popup versions. [#3817]

• ALE now handles code actions responses from language servers that directly return commands to run. [#3929]
• ALE now includes the text of a file in the textDocument/didSave notification for language servers where supported to support more language servers like Godot. [#3923]
• ALE now only sends textDocument/didSave if the language server supports it. [#3930] [#4008]
• textDocument/didSave is now dispatched after files are saved due to a rename, and ALE now respects the value of hidden to determine if other files modified should be written or not. [#4049]
• g:ale_open_list/b:ale_open_list can now be used as a threshold for opening the window after so many problems are found. [#4050]
• ALE now attempts to automatically restart language servers when they crash. [#4098]
