how to get warning/error as a lsp diagnostic popup instead of another window?

[niksingh710]

with default configuration i get warning/error in a seprate split window at bottom.

however i would like to get only the error not the warning. and also them in a lsp diagnostic not in a seperate window.

You can use g:vimtex_quickfix_ignore_filters to filter the messages. It does not allow to filter on severity, but you can use regexes to filter out warnings that you do not care about.

Further, you can set g:vimtex_quickfix_open_on_warning to 0 or false to have it only open if there are errors.

and also them in a lsp diagnostic not in a seperate window.

That is not possible. The error feature in VimTeX is based on the classic/legacy quickfix feature. There are plugins that you can use that can take quickfix errors and move them to the new diagnostic stuff, but I don't use this myself and I don't know which plugins are good enough to recommend. Sorry!

    vim.g.vimtex_quickfix_ignore_filters = 'warning';
    vim.g.vimtex_quickfix_open_on_warning = 0;

added these and now i have expected behaviour with one issue, if i keep vimtex_quickfix_ignore_filter = 'warning' then the window does not open at error also.

and doing <leader>tle says no error even if the compilation failed because of error. so any way to see that error message? like get the log manually to check why compilation failed not that window?

Ah, no, vim.g.vimtex_quickfix_ignore_filters is a list of strings, not a string. So you want

    vim.g.vimtex_quickfix_ignore_filters = { 'warning' }
    vim.g.vimtex_quickfix_open_on_warning = false

Also, note that you don't need semicolons in Lua.

Finally, I strongly recommend that you read up on options and similar in the docs, e.g. :help vimtex_quickfix_ignore_filters. The docs explain expected type and input for the various options and of course what they do.
