[[!meta title="escm: a scheme preprocessor"]]

This is my port of [eguile](http://woozle.org/~neale/src/eguile) to
|
||
|
|
gauche scheme. It uses regular expressions and as a result is faster
|
||
|
|
and easier to read. It's so tiny, in fact, that I don't feel compelled
|
||
|
|
to write much about it.
|
||
|
|
|
||
|
|
eguile looks like PHP, but with Scheme instead of Perl. If you're the
|
||
|
|
sort of person that would enjoy something like this, you probably don't
|
||
|
|
need any further description.
|
||
|
|
|
||
|
|
I use eguile along with a couple handy procedures and some makefiles to
|
||
|
|
generate my entire web space, and a few non-profit web sites I maintain.
|
||
|
|
I'd be happy to share the site-building stuff with anybody who asks, but
|
||
|
|
I'm not going to package it up until someone's interested.

Downloading it
|
||
|
|
--------------
|
||
|
|
|
||
|
|
You can download a [tarball of the latest version in git](http://woozle.org/~neale/gitweb.cgi?p=escm;a=snapshot), or check it out yourself:
|
||
|
|
|
||
|
|
git clone http://woozle.org/~neale/repos/escm
|
||
|
|
|
||
|

Reference

|
Easy squeezy:
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><?scm scheme-code ?></dt>
|
||
|
|
<dd>Evaluates scheme-code, discarding value of the last expression</dd>
|
||
|
|
|
||
|
|
<dt><?scm:d scheme-code ?></dt>
|
||
|
|
<dd>Evaluates scheme-code, displaying the value of the last expression</dd>
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
For example:
|
||
|
|
|
||
|
|
<?scm (define (square x) (* x x)) ?>
|
||
|
|
2 squared is <?scm:d (square 2) ?>
|
||
|
|
|
||
|
|
renders as:
|
||
|
|
|
||
|
|
2 squared is 4
|
||
