Implement a function like 

regex(REGEX, STRING, [POS, LEN])

to implement regular expressions.

Analysis:

We can use the STL-regex library to implement a wrapper around regex_search(), which will return the locations in combination with a match_results structure.

Implementation:

  • Implementation: New functionality was implemented as proposed by the analysis.
  • Revision: [r797]
  • Implementation test: A regular expression was tested and a erroneous one was used to test the exception handling.

Documentation:

  • [x] ChangesLog updated
  • [x] Code changes commented
  • Documentation articles:
    • [x] corresponding documentation articles updated
    • [ ] new documentation articles created
    • [ ] not needed
  • Language files:
    • [x] corresponding language files updated
    • [ ] not needed

Tests:

Added to the SW tests. Tests run without any deviation.
