# 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.
