25 This function compiles a regular expression into an internal form. It is the
26 same as \fBpcre[16]_compile2()\fP, except for the absence of the
27 \fIerrorcodeptr\fP argument. Its arguments are:
28 .sp
29 \fIpattern\fP A zero-terminated string containing the
30 regular expression to be compiled
31 \fIoptions\fP Zero or more option bits
32 \fIerrptr\fP Where to put an error message
33 \fIerroffset\fP Offset in pattern where error was found
34 \fItableptr\fP Pointer to character tables, or NULL to
35 use the built-in default
36 .sp
37 The option bits are:
38 .sp
39 PCRE_ANCHORED Force pattern anchoring
40 PCRE_AUTO_CALLOUT Compile automatic callouts
41 PCRE_BSR_ANYCRLF \eR matches only CR, LF, or CRLF
42 PCRE_BSR_UNICODE \eR matches all Unicode line endings
43 PCRE_CASELESS Do caseless matching
44 PCRE_DOLLAR_ENDONLY $ not to match newline at end
45 PCRE_DOTALL . matches anything including NL
46 PCRE_DUPNAMES Allow duplicate names for subpatterns
47 PCRE_EXTENDED Ignore whitespace and # comments
48 PCRE_EXTRA PCRE extra features
49 (not much use currently)
50 PCRE_FIRSTLINE Force matching to be before newline
51 PCRE_JAVASCRIPT_COMPAT JavaScript compatibility
52 PCRE_MULTILINE ^ and $ match newlines within data
53 PCRE_NEWLINE_ANY Recognize any Unicode newline sequence
54 PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline
55 sequences
56 PCRE_NEWLINE_CR Set CR as the newline sequence
57 PCRE_NEWLINE_CRLF Set CRLF as the newline sequence
58 PCRE_NEWLINE_LF Set LF as the newline sequence
59 PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
60 theses (named ones available)
61 PCRE_NO_UTF16_CHECK Do not check the pattern for UTF-16
62 validity (only relevant if
63 PCRE_UTF16 is set)
64 PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
65 validity (only relevant if
66 PCRE_UTF8 is set)
67 PCRE_UCP Use Unicode properties for \ed, \ew, etc.
68 PCRE_UNGREEDY Invert greediness of quantifiers
69 PCRE_UTF16 Run in \fBpcre16_compile()\fP UTF-16 mode
70 PCRE_UTF8 Run in \fBpcre_compile()\fP UTF-8 mode
71 .sp
72 PCRE must be built with UTF support in order to use PCRE_UTF8/16 and
73 PCRE_NO_UTF8/16_CHECK, and with UCP support if PCRE_UCP is used.
74 .P
75 The yield of the function is a pointer to a private data structure that
76 contains the compiled pattern, or NULL if an error was detected. Note that
77 compiling regular expressions with one version of PCRE for use with a different
78 version is not guaranteed to work and may cause crashes.
79 .P
80 There is a complete description of the PCRE native API in the
81 .\" HREF
82 \fBpcreapi\fP
83 .\"
84 page and a description of the POSIX API in the
85 .\" HREF
86 \fBpcreposix\fP
