Hello world programs

[amirouche]

Make the test called live/check-0000-hello-schemer and live/check-0001-hello-schemer-star pass green on those implementations:

• chez #24
• chibi #18
• chicken #26
• cyclone #21
• racket #32
• gambit #19
• gauche #20
• gerbil #28
• guile #27
• loko #22
• mit #30
• sagittarus #23
• kawa #25
• stklos #29
• bigloo #31
• bones #33
• Your fantastic Scheme implementation...

[lassik]

Bones is an experimental compiler from one of the Chicken hackers.

Is Racket feasible to support?

The others are definitely imporant.

More:

• Kawa
• Gauche
• Chibi

[lassik]

Sagittarius is actively developed and its maintainer is very helpful.

STklos likewise, and it's just getting define-library support.

[lassik]

MIT Scheme's define-library support is also brand new, but it should mostly work.

Bigloo doesn't have define-library, so we probably can't support Bigloo until it adds that.

[amirouche]

Re bigloo, maybe it support filename extensions such as .bigloo.scm ? We can then special case it.

NB: define-library is not a strong requirement, as long as it is possible to override default import machinery with e.g. extensions.

Re gerbil

• schemers/gerbil image is too old, see gerbil --lang r7rs scheme-containers/gerbil#1
• gerbil/scheme image use ubuntu 18.04, where env does not support --split-strings="foo bar", see Update base distro from Ubuntu 18.04 to 20.04 in docker image mighty-gerbils/gerbil#642

[amirouche]

Re Guile:

• schemers/guile is buggy There is an error while using the docker image scheme-containers/guile#1

[amirouche]

Re MIT:

• I can't figure how to make it eval / run some code

[amirouche]

Re chicken:

• csi is buggy, csc does not work, neither csm

[amirouche]

Re stklos:

• stklos/stklos official image is buggy;
• schemers/stklos can't run local/bin/hello missing scheme module.

[lassik]

Re bigloo, maybe it support filename extensions such as .bigloo.scm ? We can then special case it.

It doesn't support RnRS libraries at all; it has its own module system.

NB: define-library is not a strong requirement, as long as it is possible to override default import machinery with e.g. extensions.

That sounds a bit magical for something that's just a library collection. Yuni does that; maybe Live can run on top of Yuni?

[amirouche]

See the branch https://github.com/scheme-live/live/tree/hello-schemer it can't be merged in master at this time, and there is single commit at this time af0c67f.

I will work on #15, and include benchmarks #12 in branch forked from the hello-schemer branch.

[lassik]

Looks good!

Please add your nickname at the start of the branch names so we know who owns what branch. (No need to rename the current branches, but in the future.)

Closing this in favor of Scheme specific issues.
