Detect words or any character after some match pattern, Regex Pattern (Vim) -

I have a text file like this:

  1 textA == this textA == 1.1 textB === This is textB === 2 textC == This is textC == 2.1 Texted === This is textD === 2.1.1 Text e ==== This is textE ====  

What is the correct regex pattern to format the text above:

  == This textA == === This textB === == This is TextC == === This is textD ===  

I already try to perfoming it in vim:

  ^ \ W * - & gt; In this pattern only textA and textB changes  

I have to find out "." And no letters or words until the "=" sign is found. Any letters behind the "=" symbol will be removed. Thanks in advance for any answers and hints

Solution

  ^. \ {-} \ ze =  

explanation:

  ^. - & gt; Started with any single letter \ {-} - & gt; The mail of 0 or more of the previous atom is possible as much as possible \ ze = - & gt; Matches in any position, and sets the end of the match there: The last character is the last letter of the whole match  

In human terms:
"Find and replace text Started with any character and ended with the "=" sign.

 < Code>:% S / ^. \ {-} \ ze = //  

For more information about how to design reg.exps in Vime, see : Help pattern that is in VIM IMHO The most useful sections help.

: Help: G and : help: v may also be of interest to you. For example :

 : g / = / normal! 0dt =  

which will simulate typing on every row of 0 = one = symbol.
