scritcher

glitch art "framework", ???????? language??? something?

how do?

build depedencies (headers included):

• zig at https://ziglang.org
• libc, lilv and libsndfile
• graphicsmagick for the rotate command

plugin depedencies (only required at runtime):

• lv2 default plugins (most specifically the eg-amp plugin, will likely be there by default)
• the SWH plugins ( https://github.com/swh/lv2 )
• the Invada Studio plugins ( https://launchpad.net/invada-studio/ )

# build and install
# assumes lilv headers are at /usr/include/lilv-0, edit build.zig if different
git clone https://gitdab.com/luna/scritcher.git
cd scritcher

zig build install --prefix ~/.local/

# on your input image file
convert blah.jpg blah.bmp

# if you got the lv2 default amp plugin, this is runnable
scritcher examples/middle_amp.scri blah.bmp

# if not, the noise plugin does not depend on any lv2 plugin.
scritcher examples/noise.scri blah.bmp

// scritcher saves it on an incremental basis, so the first run will save to
// blah_g1.bmp, the second saves to blah_g2.bmp, etc.
$your_image_viewer blah_g1.bmp

using the repl

using repl works via scritcher repl scri_file.scri input_image.bmp

you type commands as you'd write the specific scritcher commands (doc/README.md), with three repl-specific ones:

• push, to push the last written command to the queue
• save, to write the queue to the given scri_file.scri file
• list, to print the current contents of the queue

this allows for quicker iteration of commands, as you can type a command, tweak its arguments, and when satisfied, push it, and work on the next one, etc.
