JS Beautifier
---------------
Written by Einar Lielmanis, <einar@jsbeautifier.org>
http://jsbeautifier.org/
Originally converted to javascript by Vital, <vital76@gmail.com>
"End braces on own line" added by Chris J. Shull, <chrisjshull@gmail.com>
Parsing improvements for brace-less statements by Liam Newman <bitwiseman@gmail.com>
Usage:
js_beautify(js_source_text);
js_beautify(js_source_text, options);
The options are:
indent_size (default 4) - indentation size,
indent_char (default space) - character to indent with,
preserve_newlines (default true) - whether existing line breaks should be preserved,
max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk,
jslint_happy (default false) - if true, then jslint-stricter mode is enforced.
jslint_happy !jslint_happy
---------------------------------
function () function()
switch () { switch() {
case 1: case 1:
break; break;
} }
space_after_anon_function (default false) - should the space before an anonymous function's parens be added, "function()" vs "function ()",
NOTE: This option is overriden by jslint_happy (i.e. if jslint_happy is true, space_after_anon_function is true by design)
brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "none" | any of the former + ",preserve-inline"
put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are.
preserve-inline will try to preserve inline blocks of curly braces
space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)",
unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65"
wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters.
NOTE: This is not a hard limit. Lines will continue until a point where a newline would
be preserved if it were present.
end_with_newline (default false) - end output with a newline
e.g
js_beautify(js_source_text, {
'indent_size': 1,
'indent_char': '\t'
});
