What hash/map based programming language exist? -

-

much lisp considered list based programming language languages considered map based?

i remember reading 1 few years back, can not longer find reference it. looked like:

[if:test then:<code> else:<more code>]

edit: , more quoted code blocks conditional evaluated. in fashion if/cond , others not special form in lisp/scheme.

the syntax above supposed map/dictionary lisp's syntax list like.

if key value of test.

then key value of .

...

that looks misc, lazy lisp maps instead of lists fundamental datatype. (it's lazy, has deep integration of metadata (similar clojure) , couple of other things, still lisp: functional, homoiconic, macros, implemented metacircular interpreter, stuff.)

here's code samples blog:

[if [> 5 10] then:[+ 5 10] else:[- 5 10]]  [let '[square:[lambda '[x:1] '[* x x]]]     '[square 12] ]  [take 20 [numbers from:0]]

unfortunately, seems besides 2 blog articles long ago, there's not going on anymore.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
