Languagetool Linter Throws Error

[0drai]

languagetool throws an error:

Here is a minimal working example

local fn = vim.fn
local install_path = '/tmp/nvim/site/pack/packer/start/packer.nvim'

vim.cmd [[set packpath=/tmp/nvim/site]]

local function load_plugins()
    local use = require('packer').use
    require('packer').startup {
        function()
            use {
                'mfussenegger/nvim-lint',
                config = function()
                    local lint = require('lint')
                    lint.linters_by_ft = {text = {'languagetool'}}
                    vim.cmd(
                        [[au BufEnter <buffer> lua require('lint').try_lint() ]])
                    vim.cmd(
                        [[au BufWritePost <buffer> lua require('lint').try_lint() ]])
                end
            }
        end,
        config = {package_root = '/tmp/nvim/site/pack'}
    }
end

-- install packer
if fn.isdirectory(install_path) == 0 then
    fn.system {
        'git', 'clone', 'https://github.com/wbthomason/packer.nvim',
        install_path
    }
    load_plugins()
    require('packer').sync()
    vim.cmd 'autocmd User PackerComplete ++once lua load_config()'
else
    load_plugins()
end

This is the error message

Error executing vim.schedule lua callback: ...vim/site/pack/packer/start/nvim-lint/lua/lint
/parser.lua:114: Vim:E474: Unidentified byte: Working on /tmp/words.txt...
Using English for file /tmp/words.txt

This is my languagetool wrapper script

#!/bin/env bash

LT=~/.local/share/LanguageTool-5.4/languagetool-commandline.jar

java -jar $LT $@

It seems like it tries to parse JSON on the first chunk of the response, i.e., “Working on …”.

An alternative to nvim-lint + languagetool, is to use the ltex-ls.

Should be fixed with #98

Not entirely sure if the offset -> line/col conversion is solid, I think it could break if there are \r\n instead of \n within the file.
