@isagalaev can we consider adding SAS to hljs? Currently pulling in his work here from https://github.com/mcaceresb/highlight-sas-stata in order to achieve this.

@isagalaev please add SAS Language to highlight.js

[antonsarov]

The PR seems to be fine, is there any reason why it has not been accepted?

[gusbemacbe]

See if the new SAS language file follows new policy and new rules released in the updated documentation.

[mcaceresb]

@gusbemacbe I'm not entirely sure what you mean? I followed the language contribution guide which does not seem to have changed.

[gusbemacbe]

Then, Maurice, let me call @ldct and @SirCmpwn to review and approve.

Please wait for the approval.

[gusbemacbe]

Ah, Maurice, I saw you sent the external documentation. Maybe in the next release the external documentation must be changed.

[mcaceresb]

@gusbemacbe Do you mean that the docs are not updated? I diffed the .rst files I had locally 2 years ago with the master branch. The changes seemed like minor clarifications and I did not see anything I missed in my original submission.

[gusbemacbe]

See: #1759

[mcaceresb]

Ok; it is not clear to me what I need to do based on that. Apologies if it supposed to be evident.

[antonsarov]

@gusbemacbe would you be able to give some directions on what is left open. We are relying on this feature and currently as @mcaceresb I don't see what is to be done. Do we have to wait for #1759 ?

[marcoscaceres]

This looks good. I'm not seeing any blockers @gusbemacbe?

[kylebarron]

@marcoscaceres Based on #1759, are you planning to move some smaller languages, like SAS, into separate NPM libraries?

[marcoscaceres]

No. Not for at least 1 year until as a community we figure out how to do it.

[marcoscaceres]

Could someone please send a PR for updating the CHANGES.md file?

[antonsarov]

@marcoscaceres Please see #1841
