Question

I have this resumed animation data list with the most representative formats:

    * » iddle 1-210
    * » run01 215-252
    * » stand up 876-987
0   -      = bindpose
1   - 48   = idle
118 - 150  = attack_idle
151 - 192  = attack 1
791 - 815  = strafe right
000 - 009 T-pose
010 - 040 walk
045 - 075 walk-back
080 - 110 walk-right-45
490 - 590 idle-1
1060 - 1120 spell-cast_01
1515 - 1590 sack_pick_up

I’m figuring how to match animation names…

I’ve made this match pattern,

 ([a-zA-Z][\w- _]+)

It returns

1: iddle 1-210
1: run01 215-252
1: stand up 876-987
1: bindpose
1: idle
1: attack_idle
1: attack 1
1: strafe right
1: T-pose
1: walk
1: walk-back
1: walk-right-45
1: idle-1
1: spell-cast_01
1: sack_pick_up

To avoid that the three starting matches contain numbers, I have tried this:

 ([a-zA-Z][\w- _]+)(?:\s\d+\s*[-]*\s*\d\s*)

but it does not match the last line:

1: iddle
1: run01
1: stand up
1: bindpose
1: idle
1: attack_idle
1: attack 1
1: strafe right
1: T-pose
1: walk
1: walk-back
1: walk-right-45
1: idle-1
1: spell-cast_01

Why?

I think is related to (?=\s but I have not found how to fix it…

EDIT: Fixed the ‘|’ between brackets

Answer 1

Use this regex to capture only names in group1

^.*?([a-zA-Z][\w -]+?)(?:(?:\s*\d+-\d+)?)$

Use multiline mode

Errors in your regex

the _ in [\w- _] is not needed since \w contains _

the \w- in [\w- _] is wrong since you are specifying a range between \w and space.

It should be [\w -] since - when used at start or end of the character class doesnt have any special meaning
