Summary

Fixes #5680

This PR fixes a bug where tags containing dollar signs (e.g., #sal$ary, #cash$back) could not be filtered using the "Has tag(s)" filter in transactions.

Changes

Bug Fixes

  • Fixed regex pattern in hasTags case to correctly capture tags without the # prefix
  • Fixed tag comparison logic (t === tag instead of t.tag === tag)
  • Changed from using regex.source to string concatenation to preserve backslash escaping
  • Updated AQL compiler's $regexp case to re-escape $ characters that are lost during object serialization, while preserving regex anchor $ patterns

Testing

  • Added comprehensive unit tests for hasTags functionality covering:
    • Simple tags without special characters
    • Tags with underscores
    • Tags with dollar signs (the main bug fix)

Technical Details

The root cause was that backslashes in escaped dollar signs (\$) were lost during object serialization when passing regex patterns through the AQL query object.

When a tag like #sal$ary is processed:

  1. It gets escaped to sal\$ary in transaction-rules.ts
  2. The pattern becomes (?<!#)#sal\$ary([\s#]|$)
  3. During serialization, the backslash is lost, becoming (?<!#)#sal$ary([\s#]|$)
  4. This causes $ to be interpreted as a regex special character (end-of-string anchor) instead of a literal $

The fix re-escapes $ characters in the AQL compiler using a smart regex that only escapes $ not followed by ), which preserves genuine regex anchors like ([\s#]|$) while fixing literal dollar signs in tag content.

Test Results

All tests pass, including the new tests for dollar sign handling:

✓ transactions can be queried by hasTags
