如何在Sublime Text 4中将每3行UUID文本合并为单行？

To merge each set of 3 UUID lines into a single line in Sublime Text 4, use this regex-based find-and-replace workflow:

Step-by-Step Instructions #

1. Open your UUID file in Sublime Text.
2. Press Ctrl+H (Windows/Linux) or Cmd+H (Mac) to open the Find/Replace panel.
3. Enable Regular Expression mode by clicking the .* button in the panel.
4. Enter these patterns:
   • Find What: ('.*',)(?:\R|$)('.*',)(?:\R|$)('.*',)(?:\R|$)
   • Replace With: $1 $2 $3\n
5. Click Replace All to apply changes to the entire file.

Explanation #

• The Find What pattern captures three complete UUID lines (each ending with a comma and either a line break or end of file) into separate groups ($1, $2, $3). This fixes your original regex issue, which captured all three lines as a single group instead of individual entries.
• The Replace With string combines the three groups into one line, separated by spaces, and adds a trailing newline to match your desired output structure.
• \R matches any line ending (LF, CRLF, CR), ensuring compatibility across different operating systems.

Handling Non-Multiples of 3 #

If your file has leftover lines (1 or 2 lines not part of a triplet), they’ll remain unchanged. To merge these too:

• For pairs: Use ('.*',)(?:\R|$)('.*',)(?:\R|$) and replace with $1 $2\n
• Single lines: No action needed—they’re already in the correct format.
