Errors ignored on open #2329

Closed davidystephenson closed 4 years ago

davidystephenson commented 4 years ago

I am using syntastic for TypeScript in vim using eslint and tsuquyomi. I expect to see all errors when I open the file. Instead, I only eslint errors. I can only see tsuquyomi errors when saving or manually running the checker.

In my .vimrc, I configure syntastic to check with tsuquyomi on open:

" Configure syntax management
let g:syntastic_error_symbol = "✗"
let g:syntastic_warning_symbol = "⚠"
let g:syntastic_javascript_checkers = ['eslint', 'standard']
let g:syntastic_cs_checkers = ['syntax', 'semantic', 'issues']
let g:syntastic_ignore_files = ['Sync/ebs/*']
let syntastic_mode_map = { 'passive_filetypes': ['less'] }
set statusline+=%#warningmsg#
set statusline+=%{SyntasticStatuslineFlag()}
set statusline+=%*
let g:syntastic_always_populate_loc_list = 1
let g:syntastic_auto_loc_list = 1
let g:tsuquyomi_disable_quickfix = 1
let g:syntastic_check_on_open = 1
let g:syntastic_typescript_checkers = ['eslint', 'tsuquyomi']
let g:syntastic_debug = 3
" Frustratingly necessary for syntastic redrawing
set autoread
set ttyfast
au FileWritePost * :redraw!
au TermResponse * :redraw!
au TextChanged * :redraw!
au QuickFixCmdPre * :redraw!
au QuickFixCmdPost * :redraw!

If I create a file with errors, for example x.ts:

const a: number = 'a'

console.log('a test:', a)

When I open the file, no errors are shown. The output from :mes shows that tsuquyomi found no errors:

If I then manually check with :SyntasticCheck, the error does show, and it is listed in :mes:

How can I make Syntastic show typescript errors when opening while ensuring I always see them as fast as possible?

You have two checkers configured for typescript: eslint and tsuquyomi. On open both eslint and tsuquyomi return no error:

syntastic: 3.530516: typescript/eslint raw: [{'lnum': 0, 'bufnr': 0, 'col': 0, 'valid': 0, 'vcol': 0, 'nr': -1, 'module': '', 'type': '', 'pattern': '', 'text': ''}]
syntastic: 3.600261: typescript/tsuquyomi raw: []

On the later run eslint still returns no error, but tsuquyomi finds a problem:

syntastic: 67.664235: typescript/eslint raw: [{'lnum': 0, 'bufnr': 0, 'col': 0, 'valid': 0, 'vcol': 0, 'nr': -1, 'module': '', 'type': '', 'pattern': '', 'text': ''}]
syntastic: 67.720950: typescript/tsuquyomi raw: [{'lnum': 1, 'valid': 1, 'col': 7, 'availableCodeFix': 1, 'filename': '/home/david/Sync/phaser3-typescript-project-template/src/x.ts', 'bufnr': 1, 'code': 2322, 't
ype': 'E', 'text': '2322[QF available]: Type ''"a"'' is not assignable to type ''number''.'}]

Now, please note that tsuquyomi is a third party checker not part of syntastic. Why does tsuquyomi returns different results on file open and on subsequent runs is a question for its maintainer(s). Sorry about that.
