scritcher command reference
---

scritcher scripts are shell-like commands separated by a semicolon.

## parameters of the arg type

some commands allow a `:N` syntax where N is an integer to use a given
argument when `scritcher` is called. so, for example, calling a script:
```
load :0;
showpath;
```

and then doing `scritcher path/to/script.scri arg` will print `arg` on the
screen and then exit.

## split and index arguments

plugin commands have a split and an index argument so that you can select
where in the file you want the plugin to be ran.

so, if you did `plugin 3 1...`, it would split the file in 3, then get the
part that is of index 1 (starting at 0).

**Keep in mind parts start from the bottom of the file.**

## `load path_or_arg`

Load a file into memory. The file MUST end with the bmp extension (and so MUST
be a bmp. feel free to put other files, no warranties are given.)

## `amp split index gain`

Run the eg-amp plugin over the given slice of the file.

## `rflanger split index delay_depth_avg law_freq`

## `eq split index lo mid hi`

default is 0.

## `wildnoise/noise split index seed repeat_bytes`

Inject random noise on the image.

the `wildnoise` version gives a harder version than `noise`.

Parameters:
 - `seed`, Random seed
 - `repeat_bytes`, Amount of bytes to preload with random data and repeat
    throughout the image slice

## `rotate deg bgfill`

Rotate the image by `deg` degrees, filling the resulting triangles with `bgfill`.

`bgfill` is a hex string, e.g `#000000`.

## `embed split index path_to_file`

embed an audio file in the given image. the file is opened with libsndfile,
which means some formats, like mp3, will not be opened.

## `quicksave`

Save the file on the same directory of the file specified by `load`, but
with a suffix on the filename (before extension).

Doing consecutive `quicksave`s will not overwrite any files, the suffixes will
just be different.
