Advanced Rename: Allow for anchor-less find/replace.

Post by raccoon »

In the Advanced Rename (as well as Advanced Move to Folder), the Old Format and New Format fields require a left/right anchor variable of %1 (%2, %3.. etc) in order to retain portions of the original object names.

I propose that if no %1 variables are used in the Old Format field, then the operation automatically gets treated as a blanket Find & Replace. Where the substring entered into Old Format is replaced with the substring entered into New Format, as it occurs anywhere in the object name.

For example:
Old: apples
New: oranges

would be the same as having typed:
Old: %1apples%2
New: %1oranges%2

In addition, if the word appears multiple times, it gets replaced multiple times. Example:
Old: .
New: -

This would replace all dots with dashes.

Feature creep: Add an option '[x] Preserve extensions' that is enabled by default.

For now:

If you enable Regular expressions, you can use
Old Format: apples
New Format: oranges

That will replace all instances of 'apples' with 'oranges'


When you want to replace characters that are part of the regular expression language (
- \ ^ ( ) { } [ ] + . $)
, you need to prefix it with the \ escape character in the Old Format.

So if you want to replace (this) with [that]:
Old Format: \(this\)
New Format: [that]

Ah hah. And here I thought regex renames actually needed \1 \2 backrefs.

So yeah, would be cool if the same behavior worked with/without regex patterns.

Thanks.

I will consider replacing all text in old format with the new format when regex is disabled.
I will consider a [x] Preserve extensions option.

Thank you for the suggestion.

There is a Find and replace dialog on my TODO list.
These options might be better suited towards this dialog.

Everything 1.5.0.1287a will now replace all occurrences of old format with new format when the old format does not contain a variable (%1 - %9).

Everything 1.5.0.1287a also adds support for detecting _-_ and - separators.

I am unfamiliar with the _-_ and - separator detection magic. Could you describe it?

The multi-file-renamer will look for the following separators (in order of priority) to generate the old format:

Code: Select all

.
 - 
_-_
-
_

This might be useful when the start of the filename doesn't match for all files.

For example:

Album - ArtistA - SongA.mp3
Album - ArtistBB - SongBB.mp3
Album - ArtistCCC - SongCCC.mp3

With the above, Everything will generate the old format as: Album - Artist%1 - %2.mp3
Note the detection of " - " with different artist lengths.
Without this separator matching, Everything would generate the old format as: Album - Artist%1.mp3

The number of separators must match for all files. Otherwise, the separator is ignored.
