ALE Files

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]

• 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 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. [#4207]
