Cannot use n-grams on Windows

[marvin-te]

Describe the bug
Hi there,
I would like to use n-gram data on my windows machine with the helix-editor. Sadly though, things don't quite work out. I just don't get any error markup anymore, when adding the appropriate config.

I hope you can help me with this.

Steps to reproduce

0. Have a working installation of ltex-ls and want to expand it's functionality by using n-grams

1. Extract files to desired directory (in my case the German n-grams are extracted in C:\Sandbox\lt-ngrams\de\{1grams,2grams,3grams}\...

2. Add config to C:\Users\<username>\AppData\Roaming\helix\languages.toml:

[language-server.ltex.config.ltex]
language = "de-DE"
additionalRules.motherTongue = "de-DE"
additionalRules.languageModel = "C:\\Sandbox\\lt-ngrams"

3. Type :lsp-restart into helix

Expected behavior
I get more suffisticated corrections.

Actual behavior
I do not get any error corrections anymore.

Ok, I think I can close this issue. It was a problem with the 20241009 version of the German ngram archive from languagetool.org. For some reason, everytime I download it, it is broken, showing varying checksums. Sometimes unzipping works, but breaks ltex-ls, sometimes unzipping doesn't even work.

Using the 20150819 version works without problem. 🤷
