Factor has the ability to save the entire state of the system into an image file
. The image contains a complete dump of all data and code in the current Factor instance.
save ( -- )
save-image ( path -- )
save-image-and-exit ( path -- )
To start Factor with a custom image, use the -i=image
command line switch; see Command line switches for the VM
One reason to save a custom image is if you find yourself loading the same libraries in every Factor session; some libraries take a little while to compile, so saving an image with those libraries loaded can save you a lot of time.
For example, to save an image with the web framework loaded,
New images can be created from scratch: Bootstrapping new images
The Application deployment
tool creates stripped-down images containing just enough code to run a single application.See alsoObject memory tools
