Noted. Thanks for checking.

I was able to bypass the problem by adding this:

autoload/ale/ale_linter.vim (line 53)

function! s:HandleTSServerDiagnostics(response, error_type) abort
    let l:linter_name = 'tsserver'

    let l:buffer = bufnr('^' . a:response.body.file . '$')

    " start edit
    if l:buffer == -1
      let l:buffer = 1
    endif
    " end edit

    let l:info = get(g:ale_buffer_info, l:buffer, {})

It seems function bufnr is returning -1 instead of 1 when I'm editing files with bracket-filenames, so I'm forcing the value to 1 instead. Clearly, this is not an actual fix, but it does seem to solve the problem for me.

Information

VIM version

NVIM v0.5.0-nightly Build type: Release LuaJIT 2.0.5

Operating System:

macOS Catalina 10.15.4 (19E287)

What went wrong

Linting does not work for files with square brackets in the name.

This is a problem with some other linting projects:

https://github.com/stylelint/stylelint/issues/4515 https://github.com/okonet/lint-staged/issues/676

Reproducing the bug

1. Create a typescript (react) file script.tsx.
2. Check that linting works.
3. Rename the file to [script].tsx.
4. Observe that linting no longer works.
