|
| 40 |
Usage: |
| 41 |
js_beautify(js_source_text); |
| 42 |
js_beautify(js_source_text, options); |
| 43 |
|
| 44 |
The options are: |
| 45 |
indent_size (default 4) - indentation size, |
| 46 |
indent_char (default space) - character to indent with, |
| 47 |
preserve_newlines (default true) - whether existing line breaks should be preserved, |
| 48 |
max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk, |
| 49 |
|
| 50 |
jslint_happy (default false) - if true, then jslint-stricter mode is enforced. |
| 51 |
|
| 52 |
jslint_happy !jslint_happy |
| 53 |
--------------------------------- |
| 54 |
function () function() |
| 55 |
|
| 56 |
switch () { switch() { |
| 57 |
case 1: case 1: |
| 58 |
break; break; |
| 59 |
} } |
| 60 |
|
| 61 |
space_after_anon_function (default false) - should the space before an anonymous function's parens be added, "function()" vs "function ()", |
| 62 |
NOTE: This option is overriden by jslint_happy (i.e. if jslint_happy is true, space_after_anon_function is true by design) |
| 63 |
|
| 64 |
brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "none" | any of the former + ",preserve-inline" |
| 65 |
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. |
| 66 |
preserve-inline will try to preserve inline blocks of curly braces |
| 67 |
|
| 68 |
space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)", |
| 69 |
|
| 70 |
unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65" |
| 71 |
|
| 72 |
wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters. |
| 73 |
NOTE: This is not a hard limit. Lines will continue until a point where a newline would |
| 74 |
be preserved if it were present. |
| 75 |
|
| 76 |
end_with_newline (default false) - end output with a newline |
| 77 |
|
| 78 |
|
| 79 |
e.g |
| 80 |
|
| 81 |
js_beautify(js_source_text, { |
| 82 |
'indent_size': 1, |
| 83 |
'indent_char': '\t' |
| 84 |
