[TxMt] Re: Single selection command that returns multiple selections?

[Graham P Heath]

Thank you for your clarification, and I’m sorry for my command/control confusion (how embarrassing!).

I had no idea that Control + T would respect a hyphen as a separator. That is awesome and is a perfect example to my use case, so thanks for that.

And that would settle it, except you peaked my interest with your last sentence: 

 Filter Through Command (which is really just an ad hoc command).

Would you mind sharing the code for that command, or point me to a similar one?

Thanks much,

Graham P Heath

It can return a snippet where subsets can be selected, but I don’t  
think this is useful for your example.

I am not sure I follow your example. If you mean control T (rather than  
command T) then this will transform “dark-theme” into  
“theme-dark” if the entire thing is selected, so here there is no  
need to “split” the selection into left/right carets, or to select  
only the first word (on the contrary).

Though when there are multiple selections, control T changes from acting  
on each selection, to acting on all selections, and will transpose them  
(swap them around).

So I think I understand what feature you want, but the example isn’t  
the best, and also, if you get multiple carets, they sort of all act on  
the actions you do, e.g. move left/right etc., so “splitting” a  
selection into a left/right caret would be very hard to subsequently  
work with, as I don’t think there are many actions that would be able  
follow this.

Here I assume you mean control W. The end result could be achieved by  
selecting the “dark-theme” instances, then do a (regexp) “Find  
All” for \b\w+\b, although I don’t know step would follow this; if  
the goal is to swap them around, it might be simplest to do a search and  
replace, though leaving out the find dialog, I would probably have  
selected “dark-” and used control W to select consecutive matches,  
then ⌘X, ⌥→, -, ⌘V, ⌫ to “swap” the order of all the  
instances.

Do you mean “each caret” (rather than “each line”)?

If the input/output option of the command is selection/replace input,  
then it should act the same as Filter Through Command (which is really  
just an ad hoc command).
