The minifier is based on the semantics of `jsmin.c by Douglas Crockford`_\. :Copyright: Copyright 2011 - 2023 André Malo or his licensors, as applicable :License: Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

See the License for the specific language governing permissions and limitations under the License. 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. - More characters are allowed before regexes. - Line terminators after regex literals are handled more sensibly - "+ +" and "- -" sequences are not collapsed to '++' or '--' - Newlines before ! operators are removed more sensibly - (Unnested) template literals are supported (ECMA-6) - Comments starting with an exclamation mark (``!``) can be kept optionally - 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 3 and 50 (for huge inputs). See the docs/BENCHMARKS file for details. rjsmin.c is a reimplementation of rjsmin.py in C and speeds it up even more. Supported python versions are 2.7 and 3.6+. .. _jsmin.c by Douglas Crockford: http://www.crockford.com/javascript/jsmin.c u André MalozApache License, Version 2.0z1.2.2jsminNFc !"#$|s7 ddl}t|ddtkr|jSn#t$rYnwxYw $n#t $r t $YnwxYwd}d}d}d}d}d }|d d }d }d } | dd} d|d|d| d} d} d} d| d| d| d} d|d|d}d|z}d$fd  $fd}|d}d}dtz} d} d} d } d!}d"}tj d#tzj }d$}tj d%tzj }tj d&tzj !d'"!"fd(}tj ||tj ||#d+#fd* }|S),aY Generate JS minifier based on `jsmin.c by Douglas Crockford`_ .. _jsmin.c by Douglas Crockford: http://www.crockford.com/javascript/jsmin.c Parameters: python_only (bool): Use only the python variant.
