hi
last time i mentioned it was a few years ago, and i just thought i let
you know that sph-sc got some interesting updates recently, and plcss
and sescript (as well as sph-lib) are still actively maintained.
"sc", for those who have not heard of it, is c written with
s-expressions. it looks a lot like scheme, but it is actually mostly a
1:1 translation, like from (+ 1 2) to 1 + 2. it does not add new
fundamental semantics or extra c code of its own. i still think it is
fun to write in because it abstracts all of the various syntactic
patterns that c has. for example it is now easy to use arbitrarily
complex function pointers with "(function-pointer return-type types
...)" in place of type identifiers. for example, a variable declaration
looks like this: "(define b int)". a function pointer variable
declaration can look like this: "(define b (function-pointer
(function-pointer char int) double))" - a pointer to a function
returning a function. granted, the corresponding c code is shorter:
"char(*(*b)(double))(int);" but the sc syntax is consistent, not "inside
out" like the c syntax, and uses english words to tell about what it is
"sescript" is very similar to sc, it is like sc but for javascript or
ecmascript. javascript on its own already feels more like scheme than c
because of its use of anonymous first-class functions. sescript adds
features like "let", implicit return and even an r6rs library form.
sometimes i was able to copy code between scheme and sescript without
change because it is so similar.
"plcss" creates css. it is written in less than 90 lines of scheme (but
imports a few bindings) and can offer most features of or more than
tools like sass and lesscss.
for details and examples, here links to the project homepages:

sescript: http://sph.mn/content/413
plcss: http://sph.mn/content/e93
while we are at it, i recently made a time and calendar calculation
library from scratch (which was pretty difficult, if anyone wants to
check out how this can be done, see the "time" libraries in sph-lib
(http://files.sph.mn/sourcecode/sph-lib/)) and this went into the
calendar on http://ytilitu.xyz/ , which runs on guile.
