ALE v3.3.0

New Features

• ALE is now tested against the following Vim versions:
  • Vim 8.0
  • Vim 9.0
  • NeoVim 0.2
  • NeoVim 0.8
• LSP completion messages with textEdit but no insertTextFormat. #4124
• b:ale_shell and b:ale_shell_arguments can now be used to set shell options
  per-buffer. #4146
• ALE now advertises codeActionLiteralSupport so language servers such as
  rust-analyzer return code actions to ALE. #4163
• An ALEGoToImplementation command has been added to go to the location
  of the implementation of a symbol via supporting language servers.
• All floating window borders characters can now be configured with
  g:ale_floating_window_border. #4215
• Floating windows can be heavily customised with
  g:ale_floating_preview_popup_opts. #4247
• The default omnicompletion regex for Racket is now '\k\+$'. #4186 #4293 #4352
• ALE completion has been tweaked to work better with C files. #4231
• ALE now always sets out_cb or err_cb for jobs to swallow messages to
  prevent Vim from excessively polling results. #4259
• ALE now outputs virtual-text messages in Vim 9. #4281 #4291
• virtual-text messages can be shown for all lines, not only the line the cursor
  is on, by setting ale_virtualtext_cursor = 'all'. #4289
• virtual-text messages are now enabled by default where supported nicely. #4396
• ALE now reports LSP linters that fail to run due to a project root not being
  set as an error, so you can figure out why nothing is happening more easily.
