How to add dynamic touch to emacs macros and or replace query?

I often have to perform several query and replace operations on a line, because, for example, I want to change all occurrences from 23 to 24 on a line, then 24-25 on the next line, etc. (usually because I write an expression in a line, which I repeat several times in subsequent lines and should slightly change) ...

A macro with Cx q, or performing multiple query replacements regularly does not seem strong enough in such situations. Is there something more general / flexible to handle substitution variables or macro variables like these that I can look at? I believe that I once met an example on the Internet where lisp expressions were introduced into certain commands in order to be more powerful, but I cannot remember this or where I read about it.

I'm not sure if this answers your question completely, but I found registers a useful tool for creating powerful macros. The most important features are:

  • C-x r n number-to-register copy number at point to register
  • C-x r + increment-register increases the value stored in the register
  • C-x r i insert-register inserts a register value into the buffer

, :

  • number-to-register
  • replace-string, insert-register, increment-register, insert-register

You can re-set the macro counter to any desired value with C-x C-k C-cto re-play the macro in another region.

And depending on how your data really looks, you could probably greatly simplify this by completely eliminating replace-regexp, and instead just moving to where you know the number, deleting the existing number and inserting the counter value in its place .
