Expected to be a fast, flexible, extensible, low memory usage, async, concurrent template engine.
Like this
(render "Hello {{var name}}!!"
:name "κeen")(let ((renderer (compile-template-string :stream "Hello {{var name}}!!")))
(funcall renderer *standard-output* :name "κeen")).

Zenekindarl perform x16 as fast as a template engine in Python in the following instant benchmark.
| Template engines | Time[sec] |
|---|---|
| Zenekindarl, SBCL 1.1.8 | 1.365 |
| Jinja2, Python 2.7.5 | 24.07 |
The benchmark code for Zenekindarl:
> (time
(with-open-file (out #P"~/Desktop/out" :direction :output :if-exists :supersede)
(let ((fun (zenekindarl:compile-template-string :stream "Hello {{var name}}!!")))
(loop repeat 1000000
do (funcall fun out :name "κeen")))))
Evaluation took:
1.625 seconds of real time
1.364707 seconds of total run time (1.302198 user, 0.062509 system)
[ Run times consist of 0.042 seconds GC time, and 1.323 seconds non-GC time. ]
84.00% CPU
1 form interpreted
3 lambdas converted
3,265,218,807 processor cycles
528,706,464 bytes consed
The benchmark code for a template engine in Python:
$ cat te.py
from jinja2 import Template
template = Template( u'Hello {{ name }}!!' )
f = open( 'out', 'w' )
for i in range( 1000000 ):
f.write( template.render( name=u'κeen' ).encode( 'utf-8' ) )
$ time python te.py
real 0m25.612s
user 0m24.069s
sys 0m0.190s
variables will be HTML escaped
{{var foo}}{{repeat 10}}hello{{endrepeat}}{{repeat n as i}}<li>{{var i}}th item</li>{{endrepeat}}
<ol>
{{loop items as item}}
<li>{{var item}}</li>
{{endloop}}
