LanguageTool error: Failed to parse JSON response

[benjamin-voisin]

First, I want to say thanks for this plugin, it is exactly what I needed !

The :LTCheck command works well, but the :LTCheckBuffer return the error "LanguageTool error: Failed to parse JSON response". I think this happens when the file to check is too big, as I do not have this error on smaller files.

Is it an issue with my LanguageTool server that does not respond to too big queries ? Could the plugin do some smart thing to cut the buffer in multiple queries ?

Thanks again

The issue seems to be about curl not being able to properly send the POST request on more complex text. From tests, the best way to curl for the entire buffer would be by using something like:

curl -s -d "language={specified language}" --data-urlencode text@file_path https://languagetools.example.org/v2/check

This is the most reliable way I found of putting the data we want inside of curl. The downside of this method is that it works over the content of the file, so the file needs to be saved, but at least it works reliably.

I will make a PR to fix this in the coming days.
