Add Imba programming language

[somebee]

Read about imba at imba.io. It has 1.9k stars on GitHub. usage

Changes required, however they may be moot given my next note.

This looks to have been manually added rather than pulled in from the grammar repo itself.

The grammar repo needs to explicitly include a license file which script/add-grammar will automatically pull in and assess.

Please remove this sample. We require only real-world usage samples and "hello world" is never real-world usage 😉

Sorry about the delay in getting to this PR. Unfortunately, it isn't popular enough on GitHub for this PR to be merged. At the moment, the stats are:

Total files found: 444
Unique public user/repos: 47
Unique owners: 23

As per the contributing guidelines at https://github.com/github/linguist/blob/master/CONTRIBUTING.md#adding-an-extension-to-a-language "we prefer that extensions be in use in hundreds of repositories before supporting them in Linguist."

Accordingly, I'll added the "Pending popularity" label.

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.

Hei,

what is the status on this? #4219 says there 58 repositories but this query shows more than 300
https://github.com/search?l=JavaScript&q=imba+fork%3Atrue&ref=advsearch&type=Repositories&utf8=✓

Thanks.

[pchaigno]

@scanf It looks like many of these repositories don't actually contain .imba files (look for repositories at the end of the search results). This is why we use the Code results in search queries instead. The search query I used in #4219 returns all .imba files on GitHub.

[aalemayhu]

@pchaigno ah, thanks for clarifying.

[manoger]

Hello. is this language popular nowadays?

[Nixinova]

There's 1K results now, minus the imba/imba and imba/imba.io repositories.
