Mainly for advanced users only. Allows setting and cleaning entry fields with regexp.
manipulate: - <destination field>: [phase]: <phase> [from]: <source field> [separator]: <value> [extract]: <regexp> [replace]: regexp: <regexp> format: <regexp> [remove]: <boolean>
Valid values for phase are: metainfo and filter, metainfo is the default behavior.
To see what results your configuration has, use --dump plugin to display all entries after execution.
When using extract functionality manipulate will join all returned groups together with separator. The default separator is single space.
Title is filled with garbage that series plugin does not like.
 The Series S01E01 720p
This could be fixed by removing the 
manipulate: - title: extract: \[\d+\](.*)
The (.*) part is what this regexp is extracting (capture group), so everything after those numbers.
Regexp can return any number of groups, value is combination of these (separated with a space).
Some badly written site has invalid URLs. Uses & instead of &
manipulate: - url: replace: regexp: '&' format: '&'
Starting from r1420 these are fixed automatically by urlfix plugin.
You can do multiple manipulates in a row, and they will be executed in order. You can also do multiple manipulates on the same field.
manipulate: - title: extract: .*\[\s*(.*)\s*\]-.* - filename: from: title - title: replace: regexp: '[\.-]' format: ' '
You can control how the regex hits are output using \1, \2, etc in format.
manipulate: - title: replace: regexp: '(.*)/(.*)/(.*)' format: '\2.\1.\3'
The series plugin operates on both the title and description fields. If you want to exclude the description field, you can simply remove it:
manipulate: - description: remove: yes
