Question

I’m using (mac)vim with tex-suite and would like to have a single regex command (or any other way) to do the following thing:

Change

\textcolor{green}{some random text}

into

some random text

This should be done for all occurrences of \textcolor{green}{} in my tex file…

Any idea?

EDIT: I need it to recognize matching braces. Here an example :

\textcolor{green}{
     with $v_\text{F}\sim10^6$m.s$^{-1}$ the massless Dirac fermions 
     velocity in pristine graphene}.

Answer 1

In my experience, things like this most often crop up during editing, and you might have the search for \textcolor{green}{ already highlighted.

In such a scenario, :global is usually my weapon of choice:

:g//norm d%diBvaBp

_{^{diBvaBp: diB (delete inner block), vaB (select block), p (put)}}

If you have surround.vim installed (recommend it!) you could remove the pair of braces simply doing dsB (delete surrounding {})

:g//norm d%dsB

Of course, you can combine it like

:g/\\textcolor{green}{/norm d%dsB

---

I just noted a potential issue when the target patterns don’t start at the beginning of a line. The simplest way to get around that is

:g//norm nNd%diBvaBp

A more involved way (possibly less efficient) would be using a macro:

/\\textcolor{green}{
gg
qqd%diBvaBpnq

Followed by something like 100@q to repeat the macro
