Convert a string using regex_replace filter python and ansible
Question:
i would convert all the lines here @catn@chickennapplenfruitnjuice into + : @cat : alln+ :@chicken: alln+ :apple : alln+ : fruit : allnjuice : all in other hand i would get this for every line + : value : all
i would use regex_replace filter to perform the task, i don’t have too much knowledge on python, i am trying to do this:
{{ '@catn@chickennapplenfruitnjuice'| regex_replace('^(?P<name>)$', '\g<name>: ALL' , multiline=True, ignorecase=True)}} but nothing happens, i am missing something here
Answers:
You can use
regex_replace(r'.+', r'+ : g<0> : all' )
to wrap each non-empty line with + : <line_here> : all text.
Note that . matches CR chars, too, and if the line endings are CRLF, you will have to replace . with [^rn].
Here, g<0> is a replacement backreference to the whole match value, no need using named capturing groups.
