# Tool to dump a marshalled version of the janet core to stdout. The
|
|
# image should eventually allow janet to be started from a pre-compiled
|
|
# image rather than recompiled every time from the embedded source. More
|
|
# work will go into shrinking the image (it isn't currently that large but
|
|
# could be smaller), creating the mechanism to load the image, and modifying
|
|
# the build process to compile janet with a built image rather than
|
|
# embedded source.

# Get image. This image contains as much of the core library and documentation that
|
|
# can be written to an image (no cfunctions, no abstracts (stdout, stdin, stderr)),
|
|
# everything else goes. Cfunctions and abstracts will be referenced from a register
|
|
# table which will be generated on janet startup.
