VSCode Snippet Help/Chaining transform

Question

I thought I was getting the hang of making my own snippets, but I can't figure out to transform a tab stop so that 'Ignore/Before/Slashes/Oh Hey Text' becomes 'OhHeyText'.

so far I have this

${4/.*\\/(.+$)/1ドル/g}

or

${4/\\s//g}

But I can't figure out how to chain the transforms together. I've read through 5 or 6 posts here on SO already, but I'm having a lot of trouble grokking the actual transformation syntax, and extrapolating that to my use case.

Thanks for any help you can give!

• Mark: What is in your tabstop 4? Text you enter, some filePath, etc.?

Answer 1

You can use

"${TM_DIRECTORY/^.*[\\/\\\\]|\\s+//g}"

See the regex demo. Details:

• ^.*[\/\\] - start of string, any zero or more chars other than line break chars as many as possible, and then / or \
• | - or
• \s+ - one or more whitespaces.

• Ben Wong: Man, you must dream in Regex, thanks a lot! I will add that this example actually did help me think about it in a new way (and wasn't just a copy/paste/forget answer)
• Wiktor Stribiżew: @BenWong I forgot to add that g is important here, it makes the regex engine replace all found occurrences in the string. Otherwise, the alternation would not help.
• Ben Wong: If you don't mind, for the sake of my learning, how would you extend this regex alternating strategy to include a requirement that wasn't about deleting, like you had to keep the first letter after a slash and make it capitalized (as a silly example).
• Wiktor Stribiżew: @BenWong If the task is to uppercase the first char after last /, you could use "${TM_DIRECTORY/^.*(?=[\\/\\\\])|[\\/\\\\]([^\\/\\\\])(?=[^\\/\\\\]*$)|\\s+/${1:/upcase}/g}"
