"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 ()
|
|
|
|
brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
|
|
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.
|
|
|
|
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.
|
|
|
|
e.g
|
|
|
|
js_beautify(js_source_text, {
|
|
'indent_size': 1,
|
|
'indent_char': '\t'
|
|
});
