ansible 2.9.5 (pip3)
The following sed command:
- function is to replace all '_' by '-' in all keys only (and not values)
within a list of dictionaries in memory
- uses character classes which are probably not supported by regex_replace:
+ [:blank:]: space and tab
+ [:space:]: tab, newline, vertical tab, form feed, carriage return, and
space
- a label and loop
sed -E ':l;
s/^([[:blank:]]*(-[[:blank:]]*)?[^[:space:]:_]*)_([^[:space:]:]*:)/\1-\3/;
tl;'
I need to use the previous sed over a yaml list of dictionaries.
If I use a shell command (such as printf "%s\n" "{{ var }}" | sed ...), the
resulting structure is not yaml anymore.
I could save the var into a file, perform the function over the file and
reopen the resulting file into memory.
However, I'm looking for a more efficient way, that is perform only memory
operation(s).
Is there a way to translate the previous sed expression into a
regex_replace command?
Or maybe there is another more ansible way to perform the same function?
