The build here is failing for two possible reasons, that I can understand:

• The extensions for YAML are not in correct order.
• According to languages.yml the .mir extension is for more than one language, therefore samples must be provided for both languages bearing the same .mir extension.

I went to the official Mirah community Github to get some examples, but all the files in their repositories have .mirah extensions. I am not sure, but it does seem to me that .mir is not a Mirah extension at all. See the Mirah Files on their github, links are given below

• files in mirah/mmeta
• files in mirah/mirah_model
• files in mirah/mirah

cc : @pchaigno

what should I do? should I remove .mir from Mirah?

Updates :

• Correcting the order of extensions already present for YAML solved one failure 😅
• I've removed .mir from Mirah as the extension for Mirah projects is .mirah

[gabru-md]

@pchaigno I've got it confirmed that .mir is not an extension for Mirah and hence can be removed from Mirah's extensions in languages.yml.
I have already done that in my Pull Request here, Please review it.
Here is the link to the issue where I got response from Mirah's Owner clarifying the doubt. 👍

That file extension dates from the initial versions of Linguist (2011). It's probably fine to remove it given the usage. @lildude ?

[gabru-md]

Oh! It has been a bug for so long 😮

[gabru-md]

Any reviews on this PR @pchaigno @lildude ? 😅

[RobQuistNL]

From what I understand the first item in the list should always be the main file extension. You can see this is the case for all other file extensions as well. (Example: https://github.com/gabru-md/linguist/blob/a12ce9b736321450108cfdced365ba146a2ffbfb/lib/linguist/languages.yml#L5063)

So the order should not be an issue either. Its probably because of the missing example files.

Please revert .yml to the top, add .mir in an alphabetical order, and then we should be good for this one IMHO :)

[gabru-md]

Okay. I'll do it. Wait for travis and then ping you.
👍

@pchaigno @lildude @RobQuistNL please review :)

[RobQuistNL]

LGTM 👍

[gabru-md]

@pchaigno can you provide with a review please.
If there are any changes I should make or it this okay ?

@lildude @pchaigno can you please review. The PR has been opened for 13 days 😅

Please be patient; Linguist is a hobby for all of the primary contributors and not our jobs. I've been AFK for over a week and I don't review PRs until reviewed by another contributor anyway.

Yep, but on this one, I'm waiting on an answer from you, @lildude :-)

Whoops 😊 That's further down my backlog 😄

Yup. Fine to remove it.

[gabru-md]

I'm sorry! I'll be patient. 😅

Well then, LGTM!

[lildude]

LGTM. Thanks for the PR, welcome to Linguist and sorry it took me so long to get back to this.

[gabru-md]

Thank you!
I am happy contributing to Linguist.
I will be taking up more issues and help solving them. 🥂
