To lower case during transformation

[conrad-chan]

Is there a way to turn values to lower case (Or other basic transformation) while substituting?

Hi,

Currently they are no transformation applied to values. Could you explain me your use case to see if this could be use more broadly and need to be added as a feature?

I replace tokens with build vars such as branch name in a yaml file, sometimes a branch name has an uppercase in it which causes the deployment to fail as the yaml as it expects values to be in lowercase.

I'll see how i could had simple transformation (tolower, toupper) without breaking changes in a future version.

With a variable that may be defined in mixed character case I would like it to be used in lower case for some substitutions.

In YAML pipeline as long as the mentioned variable is defined statically, or with the ##vso setVariable command, there can be another variable defined in lower case (with either AzDO pipeline lower() expression or in a PowerShell script).

The use case: defining the first variable in web UI (variable group or pipeline variable), and neither of them in the code, - for better maintainability.

replasetokens with transformations would do the work.

This is not available in the UI step yet. When is that planned on being added?

Hi @conrad-chan, @jjburr, @unclev, @stoopered,
Version 3.7.0 of the task is released and now supports the following transformations:

• lower: make variable value lower case. Example: #{lower(MyVar)}#
• upper: make variable value upper case. Example: #{upper(MyVar)}#
• noescape: disable variable value escaping. (this can be used if you want to inject raw JSON or XML for example). Example: #{noescape(MyVar)}#

By default the separator after the transformation name are parenthesis (and ) but if needed those can be changed when the transformation feature is enabled.
