Hello, I’m trying to remove from a string comment data with a regular expression, so I do replaceRE "(/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/)|(//.*)" "" . But I get the error “invalid syntax” but I have tested the regular expression on http://www.regexplanet.com/advanced/golang/index.html h…

See the following thread. You likely need to use proper escaping. [image] replaceRE not working for me [SOLVED] I'm trying to use replaceRE from the docs: {{ "http://gohugo.io/docs" | replaceRE "^https?://([^/]+).*" "$1" }} → “gohugo.io” So source string, pipe symbol, replaceRE, matc…

I have change the regex to (/\\*(?sU).*\\*/)|(//.*) this works, but not with a shortcode parameter. I’m using a shortcode within the markdown file {{< getfile regex="(/\\*(?sU).*\\*/)|(//.*)" >}} and I pass it to replaceRE inside the shortcode: {{ $mydata := // read data }} <div> {{ repaceRE (…

That’s odd. Does it work if you hard-code it inside the shortcode? Try double-escaping the parameter. It shouldn’t matter, but try it. {{< getfile regex="(/\\\\*(?sU).*\\\\*/)|(//.*)" >}}

With a hard-coded version: (/\\*(?sU).*\\*/)|(//.*) everything works fine, but with a parameter version it fails. If I do double-escaping the rehex will not match anymore. If I put the regex (without double-escaping) on the shortcode parameter it will not match correctly, some parts are matched,…

First off, kudos on an awesome framework for including example code into your site. The issue is that within the shortcode itself, the Go template engine is parsing the string, and it must be escaped. When passing the regexp as a parameter to a shortcode, our shortcode parser handles that, and the…

Thanks for your compliment. It will work with your solution, but I add also a default option for reducing tag complexity. I will publish the whole source of the shortcode here to read any source code from a GitHub repository: {{- $id := (.Get "id") -}} {{- $codetype := .Get "lang" -}} {{- $prefix …
