lode leroy,
The following might do roughly what you want.
(defun recompile-current-line ()
"Rerun the command on the current line in the ~/build directory."
(interactive)
(let* ((line-text (buffer-substring-no-properties
(line-beginning-position)
(line-end-position)))
(compile-command (concat "cd ~/build && " line-text)))
(shell-command compile-command)))
There are probably a couple things worth doing if you expect to have more tasks
that need automation.
1. Learn emacs lisp. (You've already hinted at this. The next steps should help
you with this.)
2. Name, save, study and edit your keyboard macros. (More below.)
3. Read the introduction to emacs lisp, `info "Emacs Lisp Intro"' brings it up.
The table of contents alone gives a good idea of what is possible.
4. Use steps 2 & 3 to learn emacs lisp.
Regarding keyboard macros: `C-x C-k e' brings up special buffer for editing
keyboard macros. It also contains hints (sometimes wrong unfortunately) about
the corresponding lisp functions involved. Here's one that inserts "foo" with
some corrections.
Macro:
f ;; self-insert-command
ooo ;; self-insert-command * 3
C-b ;; backward-char
C-k ;; kill-line
C-n ;; next-line
The corresponding elisp functions are on the right. They suggest the following
function definition:
(defun insert-foo-extravagantly ()
"Insert `foo' extravagantly with some mistakes."
(interactive)
(insert "fooo")
(backward-char)
(kill-line)
(next-line))
I hope this helps.

Subject: recompile
I want to define a keyboard macro that does the following:
copy the current line, do a few search-and-replace operations and run it in a
shell...
I haven't done anything non-trivial in elisp, so I need some help...
something along the lines of:
(defun recompile-current-line
(beginning-of-line)
(set-mark-command)
(end-of-line)
(copy-region-as-kill)
(shell-command
(replace-regexp "^" "cd ~/build && "
current-kill)))
can someone give some advice on how to implement this?
