But why ?
https://github.com/Aaronepower/tokei is written in Rust and does a great job detecting languages.

Is that what Onefetch currently uses? It detects C++ as C in the case of Godot, and it didn't detect anything for the repo of a Godot project (while GitHub detects GDScript).

it only detects the languages that are currently supported by onefetch (WIP):

C
Clojure
C++
C#
Go
Haskell
Java
Lisp
Lua
Python
R
Ruby
Rust
Scala
Shell
TypeScript
JavaScript
Php

Also tokei ignores all commented lines which is why the language distribution sometimes differs from GH.

Supported languages by tokei --> https://github.com/Aaronepower/tokei#supported-languages

Upstream issues: XAMPPRocky/tokei#305 and XAMPPRocky/tokei#67

We can leave this closed though if you want.

Ok, with the new title it makes more sense to keep this open.

We'll wait for tokei to fix it then.

Thx @aaronfranke

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

This issue still exists, though it is likely seen by the devs as low priority, so I'll probably have to bump this again later to please the stale bot.

Hi, I added the c header and cpp header to language.rs file to my fork
https://github.com/mapau/onefetch/tree/feature/add-c-cpp-header

https://github.com/Aaronepower/tokei already detects the c header and cpp header only the mapping in onefetch is missing.

Here is a PR #365

I'm not very fund of this idea of having separate entries for header files (CHeader and C++Header). I personally prefer the GitHub Linguist approach of extending C and C++ detection scope to include their respective header files:

C++:
  type: programming
  tm_scope: source.c++
  ace_mode: c_cpp
  codemirror_mode: clike
  codemirror_mime_type: text/x-c++src
  color: "#f34b7d"
  aliases:
  - cpp
  extensions:
  - ".cpp"
  - ".c++"
  - ".cc"
  - ".cp"
  - ".cxx"
  - ".h"
  - ".h++"
  - ".hh"
  - ".hpp"
  - ".hxx"
  - ".inc"
  - ".inl"
  - ".ino"
  - ".ipp"
  - ".re"
  - ".tcc"
  - ".tpp"

  C:
  type: programming
  color: "#555555"
  extensions:
  - ".c"
  - ".cats"
  - ".h"
  - ".idc"
  interpreters:
  - tcc
  tm_scope: source.c
  ace_mode: c_cpp
  codemirror_mode: clike
  codemirror_mime_type: text/x-csrc
  language_id: 41

I doubt the people over at tokei would be ready to make that shift...So, either we stick to tokei's detection rules and merge @mapau's PR, or we override the logic in Onefetch or...

Interesting about the TypeScript issue. Looks like it's caused by the files in src/qt/locale, which all have .ts extensions (guess it's the extension of Qt translation files, too).

b) perhaps this is related to C++ header detection?

Most likely. What it comes down to is that tokei, our dependency for language detection, naively using filenames instead of the actual content for categorization. github-linguist performs heuristics on file contents, helping make it much more accurate when there are conflicts with extensions. You can try creating an issue over there, but looking at the issue history it might be closed as a duplicate of XAMPPRocky/tokei#67.

I reported this issue over a year ago: XAMPPRocky/tokei#719.

Incorrect detection of Verilog using tokei.

tokei uses file extension *.vg for verilog while the more popular choice is *.v
tokei *.v is defined as COQ, all this is described in tokei issue 520

When considering a new approach, please consider verilog file identification as a useful test case.

Thanks for the report, @atluft.
I guess this also means that tokei can have a problem with V, it it is ever implemented.

@o2sh We might want to create a known-issues.md file, documenting workarounds (alternate extensions to use, tokei config file snippets, etc.).

I'd be happy to do so, but do we actually have any workaround for this? 🤔

As far as I know tokei still doesn't provide an option to allows users to override the extensions - as suggested here

Sorry, I incorrectly assumed that tokei allowed language overrides, but I guess that's not implemented yet.

Well, the only workaround that I know of is renaming all Verilog files to *.vg 😅

Coming back to a really old issue to document a potential solution:

It might be worth creating a new crate that acts as a wrapper for tokei. This wrapper would provide its own function for getting languages, adding the following:

• heuristics using regexes
• naive bayesian classification using code samples
  Basically, it should do what github-linguist does.

Also, it should probably re-export the rest of tokei's public interface to make usage easier.

Such a crate should probably be in a separate repository, as I anticipate releases occurring on a very different schedule from onefetch.

Additionally, this crate would probably need a lot of community support to provide the heuristics and code samples.

I might attempt to do this sometime, but I can't promise that it will be soon. If someone else wants to take this on, I'll be happy to help and discuss this further.

that acts as a wrapper for tokei.

You mean exposing the same set of APIs? or is it gonna reuse some of tokei's code?

If I'm understanding correctly, the new project will be similar to github-linguist but implemented in Rust. Does that mean sacrificing some performance for better accuracy?

Regardless, it's definitely an intriguing challenge. If executed well, it could gain a lot of traction, especially given the current state/limitations of existing solutions 😢.

I'd be happy to help 👍

You mean exposing the same set of APIs? or is it gonna reuse some of tokei's code?

Mostly exposing the same API. Basically a bunch of pub use. For the re-implementation of get_statistics, some code reuse might be necessary.

This could also be a fork of tokei. I was just thinking about "wrapping" tokei since AFAIK get_statistics is the only part we're not satisfied with. But maybe forking makes more sense so we wouldn't have to re-implement as much internal code 🤷

Also, since we're mentioning github-linguist, I should note that linguist actually analyzes the HEAD (or other rev) of a repository, not the filesystem, which is pretty cool. But I'm not sure if we'd want that since we display pending change stats.

So I guess the first question is: do we want to improve tokei for our purposes, or port linguist to Rust?

Hey everyone following this 👋

There's been a bit of discussion here, but to keep you all up to date: I went ahead and started a project called gengo that should be more linguist-like, to hopefully improve our language detection eventually. Unlike tokei, there can be file extension collisions, and gengo will try to pick the right language using heuristics. For example, for this comment, it would need to register ts as an XML file extension, and include a heuristic to be confident that the .ts file is actually XML.

But right now, gengo doesn't support nearly enough languages. While I can just grab the data from linguist (and maybe I eventually will), right now I'm hoping that language support grows more organically, with discussion for each added language. So if you'd like to contribute, please do! I'll definitely need help with languages that I'm unfamiliar with, especially when it comes to adding heuristics, for example for C and C++ .h header files.
