### Problem to solve [Fish](http://fishshell.com/) is cool. We use it always instead of Bash. I want to document commands in the wiki in Fish, but its syntax is not highlighted properly: ```fish set now (date) echo It is $now ``` ### Intended users <!-- Who will use this feature? If known, include any of the following: types of users (e.g. Developer), personas, or specific company roles (e.g. Release Manager). It's okay to write "Unknown" and fill this field in later. Personas can be found at https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/ --> Wiki writers that love Fish. ### Proposal <!-- How are we going to solve the problem? Try to include the user journey! https://about.gitlab.com/handbook/journeys/#user-journey --> I imagine the markdown rendering engine in gitlab should support this language. ### Permissions and Security <!-- What permissions are required to perform the described actions? Are they consistent with the existing permissions as documented for users, groups, and projects as appropriate? Is the proposed behavior consistent between the UI, API, and other access methods (e.g. email replies)? --> Shouldn't be affected. ### Documentation <!-- See the Feature Change Documentation Workflow https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html Add all known Documentation Requirements here, per https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html#documentation-requirements --> I guess it's not needed. Writers just have to write their fish snippets with: ```fish echo Your fishy code here ``` ### Testing <!-- What risks does this change pose? How might it affect the quality of the product? What additional test coverage or changes to tests will be needed? Will it require cross-browser testing? See the test engineering process for further guidelines: https://about.gitlab.com/handbook/engineering/quality/guidelines/test-engineering/ --> Absolutely no idea! :nerd: ### What does success look like, and how can we measure that? <!-- Define both the success metrics and acceptance criteria. Note that success metrics indicate the desired business outcomes, while acceptance criteria indicate when the solution is working correctly. If there is no way to measure success, link to an issue that will implement a way to measure this. --> Success would be that fish snippet highligh properly. ### Links / references
