Learning the hard way trying to run this regex:
{{ replaceRE "^\d*(-| |)" "" .Params.name }} (expected 20-test-3 -> test-3)
Would fail but it wouldn’t say why. Whittling it down it looked like the \d was the problem, which is frustrating because it is typical syntax for a digit. I had the idea that maybe the \ needed to be escaped for some reason, and when I did \\d it worked as expected… but looking on the forum, it looks like the better solution from @jmooring (Thank you!) is to surround the pattern with backticks instead to make it a string literal and not have to escape the backslashes.
{{ replaceRE `^\d*(-| |)` "" .Params.name }}
Unfortunately, the docs for findRE and replaceRE both use double-quotes, don’t explain about the backticks, and don’t have extensive examples, but the findRE does have an example of using \n in double quotes without escaping so I don’t know if that will fail as mine did because it’s not escaped or if it’ll work for some special reason.
