Please have a look at the guidelines to add support for a new language to Linguist. In particular, we'll need some evidence of in-the-wild usage across github.com.

In addition to @pchaigno's comment, and in prep for when SARL becomes more popular, this PR is missing a license for the new grammar as it has not been added using the script detailed at https://github.com/github/linguist/blob/master/CONTRIBUTING.md#adding-a-language

We'd also need to know the source and license of the samples.

[gallandarakhneorg]

The grammar and the samples are under Apache 2 License. The submodule included into this PR contains the license file: https://github.com/sarl/sarl-textmate/blob/master/LICENSE. The grammar license is also specified into the grammar file: https://github.com/sarl/sarl-textmate/blob/master/sarl.tmLanguage

Regarding the sample code, I have not put the license into the sample to mimic the samples of the other languages. The source of the sample is: https://github.com/sarl/sarl/tree/master/contribs/io.sarl.examples/io.sarl.examples.plugin/projects

Should I add some LICENSE file or comment to each of the sample files?

Thanks for the clarification of the license for the samples @gallandarakhneorg. That's all we need for them.

However, there are a few other issues still outstanding:

1. It looks like your new grammar wasn't added using the script/add-language script as the grammar license hasn't been included in this PR.
2. You're adding SARL with the extension .sarl which doesn't return many unique hits, hence @pchaigno and my previous comments about it. Your sample search is referencing many many other file types and languages and not specifically SARL. Limiting your search to just the .sarl extension returns even fewer hits.
3. There's a conflict with .gitmodules - you need up merge github/linguist's master into your fork.
4. There are still a few failing tests that need addressing - the errors in the tests should help you identify the problems and make the necessary fixes.

Closing in favor of #4219. We'll monitor the popularity of the extension there.

If you have an improved search query compared to the one used in #4219, please post it here and I'll update #4219.
