Assumptions on construction of search-terms
From your comment I assume the file-name replacing step as input for the search is:
set:
title: "{{title|replace('4K','[]')|replace('BD1080','[]')|replace('M1080','[]')}}"
So the different search-terms (set titles) are alternatives (separated by | like boolean OR):
title|replace('4K','[]')|replace('BD1080','[]')|replace('M1080','[]')
See also FlexGet docs:
Regex as solution
Assume further that you can use a regular-expression to substitute the title.
Then a regex-substitution adding a space between lower-case and upper-case letters will do:
| Step |
Value |
| Input |
ElPatriotaM1080.www.url.com.mkv |
| Wanted |
El Patriota M1080.www.url.com.mkv |
| Regex |
substitute ([a-z])([A-Z]) by \1 \2 |
| Output |
El Patriota M1080.www.url.com.mkv |
Manipulate and replace by regex
Appropriate seems the manipulate Plugin with action replace as sown in Example 4:
You can control how the regex hits are output using \1, \2, etc in format.
manipulate:
- title:
replace:
regexp: '(.*)/(.*)/(.*)'
format: '\2.\1.\3'
⚠️ Caution: Regex matches are ignore-case by default
Since the regex is case-sensitive (depends on different upper-case and lower-case characters), the default regex-flags of the manipulate replace-by-regex (IGNORE and UNICODE) must be disabled explicitly by surrounding the regex with disabled inline-flag i like (?-i:<regex>).
Config snippets
In this case it could look like separating the lower-case (first group ([a-z]) and insert by reference \1) from upper-case (second group ([A-Z]) and insert by reference \2) by a space between.
Additionally disabling the i we need to config: (?-i:([a-z])([A-Z])).
manipulate:
- title:
replace:
regexp: '(?-i:([a-z])([A-Z]))'
format: '\1 \2'
or alternatively, without capturing but with a positive look-ahead as (?=[A-Z]) then inserting a space (with switched-off ignore-case flag):
manipulate:
- title:
replace:
regexp: '(?-i:(?=[A-Z]))'
format: ' '
Demo in pure Python
A working demo in pure Python shows how to replace file-names.
It was adapted from How to replace camelCasing in all files in a folder using Python or c#?:
import re
old_name = 'ElPatriotaM1080.www.url.com.mkv'
print(f"Given: '{old_name}'")
flags=re.I # default for FlexGet's replace-plugin: ignore-case
regex_1 = '(?=[A-Z])'
regex_1_no_ignore = '(?-i:(?=[A-Z]))'
new_name = re.sub(regex_1, ' ', old_name, flags=flags)
print(f"Regex 1 (I on ): '{new_name}'")
new_name = re.sub(regex_1_no_ignore, ' ', old_name, flags=flags)
print(f"Regex 1 (I off): '{new_name}'")
regex_2 = r'([a-z])([A-Z])'
regex_2_no_ignore = r'(?-i:([a-z])([A-Z]))'
new_name = re.sub(regex_2, r'\1 \2', old_name, flags=flags)
print(f"Regex 2 (I on ): '{new_name}'")
new_name = re.sub(regex_2_no_ignore, r'\1 \2', old_name, flags=flags)
print(f"Regex 2 (I off): '{new_name}'")
Prints:
Given: 'ElPatriotaM1080.www.url.com.mkv'
Regex 1 (I on ): ' E l P a t r i o t a M1080. w w w. u r l. c o m. m k v'
Regex 1 (I off): ' El Patriota M1080.www.url.com.mkv'
Regex 2 (I on ): 'E lP at ri ot aM1080.w ww.u rl.c om.m kv'
Regex 2 (I off): 'El Patriota M1080.www.url.com.mkv'
Both regex-approaches (1+2) have almost the same effect: space inserted before upper-case letters. However, the ignore-case flag (whether "I on" or "I off") has unexpected impact on the result.
