[PATCH] command line argument not passed on linux
Apr 14th, 2010, 7:06pm  
btw, the bug tracker is still broken.

This patch builds on my previous patch on Slow startup when using System VM on Linux. Basically the linux startup script didn't pass its command line argument to processing.

Code:

Nice one, so now you can open processing on the sketch of your choice, avoiding all that annoying filechooser stuff. Smiley

Basically yes. With the patch you can now start Processing on a sketch without the file chooser.

However, I haven't been able to successfully execute "processing --run mysketch.pde" to "run sketch without opening PDE"[1] which will be very useful to integrate processing with other text editors/IDE or integration to automated build system.

[1] currently this just opens the sketch in PDE

Found it. Basically, instead of launching processing with 'java processing.app.Base "$@"', you launch with 'java processing.app.Commander "$@"' instead and passes the command line argument to the launcher script like:
processing --run --sketch=/home/username/sketchbook/sketch/ --output=/tmp/

However, apparently at the moment, the class processing.app.Commander is a little bit fragile, it causes Processing to crash with ArrayIndexOutOfBoundsException if you use ~ expansion (i.e. you can't use ~/sketchbook/sketch since Processing expands it to /current/working/directory/~/sketchbook/sketch which is unlikely to exists) and you face NullPointerException if you point to the .pde instead of the sketch directory.
