formating xml in vim

2009-03-28T08:14:00+01:00

i often have to work with xml files that are autogenerated and look very ugly i defined a short keymapping in my .vimrc file that calls xmllint --format - on the current buffer

map xf <ESC>:%!xmllint --format -<CR>

open any xml file and press 'xf' in command mode.

SuperCollider on Linux

2008-08-17T09:35:00+02:00

Today i have installed supercollider on my ubutu system following this instructions. SuperCollider is a environment and programming language for audio synthesis simliar to chuck. SuperCollider can run on a network and uses OSC events for comunication.

After looking around in the source tree i found a plugin for vim :-)

Installations is a bit quirky (the folders 'ftpplugin', 'syntax' and 'intend' needed to be copied to ~/.vim by hand) but now i can edit my sc code using my vim - veeeery cool :-)

single lines of code can be sent to the server using F6 codeblocks are sent to the server using F5.

s.boot
(
c = { arg f=900;
    var x;
    x = SinOsc.ar(f);
    x * 0.1
}.play;
)

c.set(, 400);
c.set(, 670);

to start te server the first line has to be sent to sclang (using F6). Then the code block starting line 2 is sent to the server (using F5)... tata - a sine wave.

sending the last 2 lines (F6 again) change the frequency of the running synth.

F12 can be used to turn all sounds off.
