# how do?
|
|
|
|
## build depedencies (headers included):
|
|
- zig at https://ziglang.org
|
|
- libc, lilv and libsndfile
|
|
- graphicsmagick for the `rotate` command
|
|
- readline (for repl)
|
|
|
|
## 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/ )
|
|
- abGate plugin
|
|
- MDA plugins
|
|
- Calf plugins
|
|
|
|
```bash
|
|
# 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 four repl-specific ones (semicolons do not apply):
|
|
- `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
|
|
- `quit`, to exit
|
|
|
|
After a non-REPL command, such as an effect, the program pointed by
|
|
`SCRITCHER_RUNNER` will run as argument to the `runqs` command. By default,
|
|
the program run will be `ristretto` (as it is my preffered image viewer,
|
|
considering it was able to handle when some images went broke)
|
|
|
|
this allows for quicker iteration of commands, as you can type a command, see
|
|
the image changes as fast as possible, tweak its arguments,
|
|
and when satisfied, `push` it, and work on the next command, etc.
