vim and auto reload the processing-java

in Integration and Hardware • 1 month ago

Hi there,

I am coding processing in vim, and I was wondering if there was a way to auto reload the code when I change it, something almost like live coding. I was trying to fool around with incrond and incrontab which should be promising but nothing yet on this front. That's what I have for my incrontab:

/home/damaru/sketchbook/nature/ IN_MODIFY /usr/bin/processing-java --sketch=/home/damaru/sketchbook/nature / --output=/home/damaru/nature/ --run --force

but there is something about the export display that I need to fit in there so that the incron can trigger the processing-java correctly.

Anyone else has resolve this autoloading type of problem from a different editor?

This has been done for some time in ruby-processing via a "watch-mode", however that does not work on P3D or P2D, where sketches don't seem to get shutdown correctly. May'be better to have couple of sessions going via tmux?

Yep that's how I am doing it now in tmux, with the processing-java running in one bottom split and the vim on the top. (and irssi at the bottom, although processing irc is not really alive these days!)

Yes the ruby way would be a good avenue, I am also thinking of what node.js has to offer...

yep I though so:

hum but that seems to be some sort of processing.js integrationg without the real power of processing... it might still be better for me to use the incron...

well I create a 'watch' bash script that does the trick as long as there is no other java application running, using the inotify-tool in linux.

Here is the script if anyone wants to use it, or improve it !

#!/bin/bash
while inotifywait -e modify /home/damaru/sketchbook/nature/; do
ps cax | grep java > /dev/null
if [ $? -eq 0 ]; then
echo "killing java"
killall java
exec -a processing /usr/bin/processing-java --sketch=/home/damaru/sketchbook/nature/ --output=/home/damaru/nature/ --run --force &
else
echo "Running the Sketch"
exec -a processing /usr/bin/processing-java --sketch=/home/damaru/sketchbook/nature/ --output=/home/damaru/nature/ --run --force &
fi
done

So it re-launch the processing-java each time you save your sketch from any editor. I am sure there is more elegant way to do that but it's working for me.

Just tried it with two regular terminals, seems to work just fine, I expect there is no reason why sketch directory needs to be hard coded, so it could be rather useful (for linux users). If you were fortunate enough to choose Archlinux all you need is to do following, and use damaru's script, or my modified version.

sudo pacman -S incron
sudo pacman -S inotify-tools

Also no problem with P3D sketches, so I might look into something similar for ruby-processing.

Here's my modified script, I think it is better to use /tmp for output, and of course script now takes an argument.

./watch "nature"

#!/bin/bash
while inotifywait -e modify /home/foo/sketchbook/$1; do
ps cax | grep java > /dev/null
if [ $? -eq 0 ]; then
echo "killing java"
killall java
exec -a processing /usr/bin/processing-java --sketch=/home/foo/sketchbook/$1/ --output=/tmp/$1/ --run --force &
else
echo "Running the Sketch"
exec -a processing /usr/bin/processing-java --sketch=/home/foo/sketchbook/$1/ --output=/tmp/$1/ --run --force &
fi
done
