exposing slim Liquid Rebol

The dataflow framework for Rebol is called Liquid and is available from rebol.org as a SLiM library.

If you are new to this as I am, it is not obvious how to proceed.

First you need both slim.r and liquid.r

Slim can be found at rebol.org in the scripts.
You can download liquid or retrieve it from the Rebol console by visiting Liquid
to either get the file or run the one-line script at the Rebol console.

Start by loading SLiM with

do %slim.r

and then try

do %liquid.r

The important liquid function is liquify. An attempt at

source liquify

or

help liquify

will show that nothing is yet available.

Start by checking the SLiM paths with

slim/paths

which should be an empty block.

I am using local code (liquid.r and slim.r are in my Rebol directory) so I just do this:

slim/paths: [%.]

Now I check my SLiM path to liquid this way:

slim/find-path %liquid.r

which gives me my Rebol path.
Now I can do the two key bits:

lq: slim/open 'liquid none ; gets any version

and then expose that lq library with

slim/expose lq none ; replace none later with a blk of funcs

Now you can test with a simple test for the liquify true? function with

source true?

You are now ready to use the liquid documentation at Steel quickstart or the Steel Liquid page.
