Filename Cleanup Using Only RegEx in BRU (Simple OFF, v2 OFF

[elewan9]

Only Using REGEX(without using replace (3) or remove (4), charater translation etc.

(currently simple is unchecked, v2 unchecked) in bulk rename utility version 4.0.0.8

rename=

Code: Select all

!!k$h!t @nd Ra~~```hul..........Propo$..-..ed___-____ H__-erWearing Cr!cket Jersey[])(][)(}}{{[][Wedding](M@nd@p) {Gulabjamun}[Flew Barat.mkv

into=

Code: Select all

Iikshit And Rahul Proposed Her Wearing Cricket Jersey Wedding Mandap Gulabjamun Flew Barat.mkv

(reg ex should be able to clean such type of names).

Since its many different replacements, should put the checkmark inside for "v2".
Then can use /g to say "global, so then a "Match" and "Replace" something like...

!/g(?X)@/g(?X)\$/g(?X)[][{}()~`._-]+/g(?X)([a-z])([A-Z])/g(?X)(^| )(.)/g
i(?X)a(?X)s(?X)(?X)$1 $2(?X)$1\u$2

If needing to remove other-characters, can add them into the underlined-characters before "-".

thank you so much..

after=

if i had to also truncate filename length (lets say to 75 characters max, excluding extension), how would these be modified???

match=

Code: Select all

!/g(?X)@/g(?X)\$/g(?X)[][{}()~`._-]+/g(?X)([a-z])([A-Z])/g(?X)(^| )(.)/g

replace=

Code: Select all

i(?X)a(?X)s(?X)(?X)$1 $2(?X)$1\u$2

(v2 on, simple off)

Please ignore last messege.

So i tested on another file names, it fails. sadly. beyond my capacity to fix it. (i am also truncating filename at 75)

case2==> UNWANTED RESULT

Code: Select all

after=

Code: Select all

Wi Ththe Swords    Under   Grandse Mester Arrivesa An The Of In Silence Two.mkv

Here’s the ideal truncated version (75 characters max) of case 2 filename:-

Code: Select all

With The Swords Under Grand Semester Arrives A An The Of In Silence Two Full.mkv


((((problems in case2=The following issues occur with the current regex cleanup:

1. "WiTh.the" becomes "Wi Ththe" instead of "With The" — the period is removed without inserting a space.
2. "Gr@nd_$eMe$ter" becomes "Grandse Mester" but "$" is inconsistently replaced, sometimes duplicated or misplaced.
3. "Arr!ves__a" becomes "Arrivesa" instead of "Arrives A" — the words get merged due to multi-symbol deletion.
4. Multiple underscores like "__" and "____" remove separation between words, causing words to merge or collapse.
5. Double or triple spaces (e.g., after "Swords" or "Under") are preserved instead of being normalized to a single space.
)))

case 3= getting unwanted result
before=

Code: Select all

A.Stranger.by.the.Hill.{2024}.[1080p].10bit.IT.WEBRip.(Hindi).DD5.1.x265.HEVC-Ospreay.mp4

after=

Code: Select all

AStrangerbythe Hill20241080p10bit ITWEBRip Hindi DD51x265HEVCOspreay.mp4

ideal output=

Code: Select all

A Stranger By The Hill 2024 1080p 10bit IT Webrip Hindi DD5 1 x265 Hevc Ospreay.mp4


case 3 problems=1. Dots (.) between words like "A.Stranger.by.the.Hill" are removed without being converted to spaces, causing merged words.
2. Braces {}, brackets [], and parentheses () are stripped without spacing, leading to glued words like "Hill2024".
3. No space is added between year and resolution, causing "20241080p" instead of "2024 1080p".
4. Uppercase-lowercase transitions like "ITWEBRip" are not properly separated into "IT WEBRip".
5. No consistent spacing between elements like "Hindi", "DD5.1", "x265", etc., reducing readability.
