Jump to match of regex

Jump to match of regex

[Joerg Schuster]

Hello,

In a file with the following structure


'bla': {
     bli : 1
     blo : 2
},

'ble': {
     bli : 3
     blo : 4
},

I would like to jump from "^'" to "^'" instead of jumping from line to
line with C-n. I know I could do a regexp-search, but I want to be
able to edit the items without having to start a new regexp-search
afterwards.

How can this be done?

You could record a keyboard macro that does the regexp search
you want, something like:

C-x (         ; start recording keyboard macro
C-1 C-s       ; start a regexp isearch
^'            ; search for ^'
RET           ; come out of isearch
C-x )         ; finish recording keyboard macro

Point is now after ^'. (i.e. on the b in 'bla').

You can now call the keyboard macro with C-x e, to move to the
next occurance of ^'.

If you don't do any other regexp searches while you're editing the items,
C-M-s C-s will search again for the previous regexp.

Set `paragraph-start' and `paragraph-separate' to "'" (either put these
settings in the local variables section of the file, or if you have many
files with this structure, make a function and put it in
`auto-mode-alist').

Then you can jump from ^' to ^' with the commmands `backward-paragraph'
(C-up or M-{) and `forward-paragraph' (C-down or M-}).

Not quite what you're asking for, but might work as well depending
on other things you haven't mentioned:

- forward-paragraph and backward-paragraph (bound to M-{ and M-})
- forward-sexp and backward-sexp (M-f and M-b)
- forward-page and backward-page (C-x ] and C-x [), which may require
  you to set the `page-delimiter' variable accordingly.

I forgot beginning-of-defun/end-of-defun bound to C-M-a and C-M-e
and which might also need setting up defun-prompt-regexp to something
like "^'[^{]*".

M-x occur "^'"
