| - Javascript Minifier
|
| -=====================
|
| -
|
| -rJSmin is a javascript minifier written in python.
|
| -
|
| -The minifier is based on the semantics of `jsmin.c by Douglas Crockford`_\.
|
| -
|
| -The module is a re-implementation aiming for speed, so it can be used at
|
| -runtime (rather than during a preprocessing step). Usually it produces the
|
| -same results as the original ``jsmin.c``. It differs in the following ways:
|
| -
|
| -- there is no error detection: unterminated string, regex and comment
|
| - literals are treated as regular javascript code and minified as such.
|
| -- Control characters inside string and regex literals are left untouched; they
|
| - are not converted to spaces (nor to \n)
|
| -- Newline characters are not allowed inside string and regex literals, except
|
| - for line continuations in string literals (ECMA-5).
|
| -- "return /regex/" is recognized correctly.
|
| -- "+ +" and "- -" sequences are not collapsed to '++' or '--'
|
| -- Newlines before ! operators are removed more sensibly
|
| -- rJSmin does not handle streams, but only complete strings. (However, the
|
| - module provides a "streamy" interface).
|
| -
|
| -Since most parts of the logic are handled by the regex engine it's way
|
| -faster than the original python port of ``jsmin.c`` by Baruch Even. The speed
|
| -factor varies between about 6 and 55 depending on input and python version
|
| -(it gets faster the more compressed the input already is). Compared to the
|
| -speed-refactored python port by Dave St.Germain the performance gain is less
|
| -dramatic but still between 1.2 and 7. See the docs/BENCHMARKS file for
|
| -details.
|
| -
|
| -rjsmin.c is a reimplementation of rjsmin.py in C and speeds it up even more.
|
| -
|
| -Both python 2 and python 3 are supported.
