Hugo - 获取视频标题并将其转换为 URL

Question

I'm working with Hugo and have a use case where there are a lot of various video titles that all follow roughly the same considerations:

• remove all underscores and replace with dashes
• remove all dashes with spaces on either side and replace with a dash with no spaces
• remove all special characters (? and !) and replace with nothing
• remove all periods and replace with dashes
• remove all remaining spaces and replace with dashes
• everything lowercase

So far I have the following code written out, and I'm trying to figure out how to streamline it.

                          {{ $step1_title := replace .title "_" " " }}
                          {{ $step2_title := replace $step1_title " - " "-" }}
                          {{ $step3_title := replace $step2_title "?" "" }}
                          {{ $step4_title := replace $step3_title "." "-" }}
                          {{ $step5_title := replace $step4_title " " "-" | lower }}
                          {{ $step5_title }}

It seems like a lot of steps, and doesn't account for both? and.. I'm assuming replaceRE would be more appropriate for that step, yet it won't recognize those characters when defined with [?]|[!] . Any pointers for making the above more efficient would be much appreciated.

For others looking for an answer - Hugo does actually have a built-in function called urlize that does exactly this!

For the curious, there is an opposite function that "humanizes" the string and returns it with separators removed and the first letter capitalized:
