I’ve spent the whole afternoon writing two small scripts. What did I do?
My desktop is basically one Emacs instance beneath one Aterm. (Well,
there’s a lot of stuff around it, but that doesn’t matter here.) When
I code, I write the programs in Emacs, and run them in Aterm.
Switching between those two windows is easy, I simply press M-Tab.
This is a feature by Enlightenment. However, when my code raises an
unhandled exception, there was no easy way to jump directly to the
error; I had to jump to and retype the line number of the erroneous
file.
This has changed now. I simply run my programs as usual, but write ete before:
$ ete ruby fuckup.rb
fuckup.rb:1: undefined method `fuckup' for main:Object (NoMethodError)
To handle this (trivial) error, I simply switch to Emacs and type C-x
:. Emacs will now load the output of ete and jump to the first
(mostly only) error. I could use C-x ` if I had several errors.
(Unlikely with Ruby, but maybe a C extension…)
You can download ete here: ete
(shell script), ete.el
(elisp).
On a side note, put this into your .emacs:
;; Make ruby-mode usable for hs-minor-mode.
(add-to-list 'hs-special-modes-alist
(list 'ruby-mode
(concat ruby-block-beg-re "\|{")
(concat ruby-block-end-re "\|}")
"#"
'ruby-forward-sexp nil))
Now open some lengthy Ruby file, and do:
M-x hs-minor-mode
M-x reveal-mode
Move over some defs, press C-c @ C-l (better rebind that :P), and be astonished
moving your cursor in and out. ;-) Cool, eh?
