oops command lives

years ago i saw my dad working in a terminal and i could have sworn i typed "oops " when he made a typo and it worked: the command was fixed and rerun, he didn't need to retype the whole thing. i always wanted the oops command.

however, it didn't exist, or at least as i knew it. so i wrote a portable version of it (it seems it exists in zsh, a shell i just don't use). the python part of it is really simple, just a levenshtein distance calculator and a replacement engine. you need to create a command alias for it however:

ksh, sh, bash:

$ alias oops='history>/tmp/oops_history && ~/bin/oops.py'

csh and derivatives:

% alias oops 'history > /tmp/oops_history && ~/bin/oops.py'

here's a brief example of it in action:

$ emacss ~/bin/oops.py
ksh: emacss: not found
$ oops emacs
[ emacs opens and voila, working ... ]

i make a lot of typos and rather than cutting, pasting, fixing the line this makes it easier. some bugs and limitations:

i need to make it use the damerau distance, which is better for spelling errors)
not extensively field tested at all
it doesn't leave a corrected mark in your history file
it doesn't work for shell built-ins (e.g. cd)

let me know if you're interested in playing around with it.

translate button

i work with a lot of foreign language websites, most in languages i do not read. to help me with that i often use google translate. but, i got sick of copying and pasting URLs or text, so i built this translate button for firefox.

it works like this: when you're on a page and you want to translate it, surf to the "translate" bookmark (i've located mine in the bookmark toolbar folder in ffox). poof, automagically translated into english. the magic is that the bookmark is javascript that will construct the proper URL for your current page as a target of google translate, and then surf you there. voila.

make a "translate" bookmark and make this the "location" in its properties. now you, too, can have a translate button.

javascript:var h = escape(location.href); 
           newurl = 'http://translate.google.com/translate
?u=' + h + '&hl=en&ie=UTF-8&sl=*&tl=en';
           document.write(newurl);
           window.location = newurl;

paste that code in. simple as that. if you need to change the target language you can change "tl=en" to another laguage (e.g. "es" or "fr"). the source language is automatically determined by google translate (see "sl=*").
