Textwrangler grep正则表达式引用？

Question

我正在搜索Textwrangler中使用的一个全面的表/正则表达式列表。手册是不错的，但它缺乏一个概览，可以检查快速参考备忘单。

here you go

我挑选了以下几部分：

模式修饰符(开关)

i             Case-insensitive
m             Multiline   : allow the grep engine to match at  ^ and $ after and before at \r or \n.
s             Magic Dot   : allows . to match \r and \n
x             Free-spacing: ignore unescaped white space; allow inline comments in grep patterns.

(?imsx)       On
(?-imsx)      Off
(?i-msx)      Mixed

Regex Meta-字符：

.             Any character except newline or carriage return
[ ]           Any single character of set
[^ ]          Any single character NOT of set
*             0 or more previous regular expression
*?            0 or more previous regular expression (non-greedy)
+             1 or more previous regular expression
+?            1 or more previous regular expression (non-greedy)
?             0 or 1 previous regular expression
|             Alternation
( )           Grouping regular expressions
^             Beginning of a line or string
$             End of a line or string
{m,n}         At least m but most n previous regular expression
{m,n}?        At least m but most n previous regular expression (non-greedy)
\1-9          Nth previous captured group
\&            Whole match                                     # BBEdit: '&' only - no escape needed
\`            Pre-match                                       # PCRE?  NOT BBEdit
\'            Post-match                                      # PCRE?  NOT BBEdit
\+            Highest group matched                           # PCRE?  NOT BBEdit
\A            Beginning of a string
\b            Backspace(0x08)(inside[]only)                   # PCRE?
\b            Word boundary(outside[]only)
\B            Non-word boundary
\d            Digit, same as[0-9]
\D            Non-digit

换例运算符

\E            Change case - acts as an end delimiter to terminate runs of \L & \U.
\l            Change case of only the first character to the right lower case. (Note: lowercase 'L')
\L            Change case of all text to the right to lowercase.
\u            Change case of only the first character to the right to uppercase.
\U            Change case of all text to the right to uppercase.

白色或非白色-空间

\t            Tab
\n            Linefeed
\r            Return
\f            Formfeed
\s            Whitespace character equivalent to [ \t\n\r\f]
\S            Non-whitespace character

\W            Non-word character
\w            Word character[0-9A-Za-z_]

(?>)          Nested anchored sub-regexp stops backtracking
(?imx-imx)    Turns on/off imx options for rest of regexp
(?imx-imx:…)  Turns on/off imx options, localized in group    # '…' indicates added regex pattern
