\section{\class{wxMouseEvent}}\label{wxmouseevent}
|
||||
|
||||
This event class contains information about mouse events.
|
||||
See \helpref{wxWindow::OnMouseEvent}{wxwindowonmouseevent}.
|
||||
|
||||
{\bf NB: } Note that under Windows mouse enter and leave events are not natively supported
|
||||
by the system but are generated by wxWindows itself. This has several
|
||||
drawbacks: the LEAVE\_WINDOW event might be received some time after the mouse
|
||||
left the window and the state variables for it may have changed during this
|
||||
time.
|
||||
|
||||
{\bf NB: } Note the difference between methods like
|
||||
\helpref{LeftDown}{wxmouseeventleftdown} and
|
||||
\helpref{LeftIsDown}{wxmouseeventleftisdown}: the formet returns {\tt TRUE}
|
||||
when the event corresponds to the left mouse button click while the latter
|
||||
returns {\tt TRUE} if the left mouse button is currently being pressed. For
|
||||
example, when the user is dragging the mouse you can use
|
||||
\helpref{LeftIsDown}{wxmouseeventleftisdown} to test
|
||||
whether the left mouse button is (still) depressed. Also, by convention, if
|
||||
\helpref{LeftDown}{wxmouseeventleftdown} returns {\tt TRUE},
|
||||
\helpref{LeftIsDown}{wxmouseeventleftisdown} will also return {\tt TRUE} in
|
||||
wxWindows whatever the underlying GUI behaviour is (which is
|
||||
platform-dependent). The same applies, of course, to other mouse buttons as
|
||||
well.

functions that take a wxMouseEvent argument.

\constfunc{void}{GetPosition}{\param{wxCoord*}{ x}, \param{wxCoord*}{ y}}
|
||||
|
||||
\constfunc{void}{GetPosition}{\param{long*}{ x}, \param{long*}{ y}}

\membersection{wxMouseEvent::IsButton}
|
||||
|
||||

|
||||
|
||||

|
||||
that may be tested using {\it ButtonDown}).
|
||||
|
||||
\membersection{wxMouseEvent::Leaving}\label{wxmouseeventleaving}
|
||||
|
||||
\constfunc{bool}{Leaving}{\void}
|
||||
|
||||
Returns TRUE if the mouse was leaving the window.
|
||||
|
||||
See also \helpref{wxMouseEvent::Entering}{wxmouseevententering}.

|
||||
\membersection{wxMouseEvent::LeftDClick}
|
||||
|
||||
\constfunc{bool}{LeftDClick}{\void}
|
||||
|
||||

|
||||
|
||||
\constfunc{bool}{LeftDown}{\void}
|
||||
|
||||
Returns TRUE if the left mouse button changed to down.

|
||||
|
||||
\constfunc{bool}{LeftIsDown}{\void}
|
||||
|
||||
Returns TRUE if the left mouse button is currently down, independent
|
||||
of the current event type.
|
||||
|
||||
Please notice that it is {\bf not} the same as
|
||||
\helpref{LeftDown}{wxmouseeventleftdown} which returns TRUE if the left mouse
|
||||
button was just pressed. Rather, it describes the state of the mouse button
|
||||
before the event happened.
|
||||
|
||||
This event is usually used in the mouse event handlers which process "move
|
||||
mouse" messages to determine whether the user is (still) dragging the mouse.
|
||||
|
||||
\membersection{wxMouseEvent::LeftUp}
|
||||
|
||||
\constfunc{bool}{LeftUp}{\void}
|
||||
|
||||
Returns TRUE if the left mouse button changed to up.

|
||||
|
||||
Returns TRUE if the middle mouse button changed to down.
|
||||
|
||||

|
||||
|
||||
\constfunc{bool}{MiddleIsDown}{\void}

|
||||
of the current event type.
|
||||
|
||||
\membersection{wxMouseEvent::MiddleUp}
|
||||
|
||||
\constfunc{bool}{MiddleUp}{\void}
|
||||
|
||||

|
||||
|
||||
Returns TRUE if the right mouse button is currently down, independent
|
||||
of the current event type.

|
||||
|
||||
\constfunc{bool}{RightUp}{\void}
|
||||
|
||||

See WHATSNEW for change listing.
|
||||
|
||||
installation notes:
|
||||
--------
|
||||
Read the comments at the beginning of Makefile before running.
|
||||
|
||||
Utils.h contains some things that just might have to be modified on
|
||||
some systems, as well as a nested include (ugh) of <assert.h>.
|
||||
|
||||
The "fake" directory contains quick-and-dirty fakes for some header
|
||||
files and routines that old systems may not have. Note also that
|
||||
-DUSEBCOPY will make utils.h substitute bcopy() for memmove().
|
||||
|
||||
After that, "make r" will build regcomp.o, regexec.o, regfree.o,
|
||||
and regerror.o (the actual routines), bundle them together into a test
|
||||
program, and run regression tests on them. No output is good output.
|
||||
|
||||
"make lib" builds just the .o files for the actual routines (when
|
||||
you're happy with testing and have adjusted CFLAGS for production),
|
||||
and puts them together into libregex.a. You can pick up either the
|
||||
library or *.o ("make lib" makes sure there are no other .o files left
|
||||
around to confuse things).
|
||||
|
||||
Main.c, debug.c, split.c are used for regression testing but are not part
|
||||
of the RE routines themselves.
|
||||
|
||||
Regex.h goes in /usr/include. All other .h files are internal only.

|
||||
New in alpha3.8: Bug fix for signed/unsigned mixup, found and fixed
|
||||
by the FreeBSD folks.
|
||||
|
||||
New in alpha3.7: A bit of cleanup aimed at maximizing portability,
|
||||
possibly at slight cost in efficiency. "ul" suffixes and "unsigned long"
|
||||
no longer appear, in particular.
|
||||
|
||||
New in alpha3.6: A couple more portability glitches fixed.
|
||||
|
||||
New in alpha3.5: Active development of this code has been stopped --
|
||||
I'm working on a complete reimplementation -- but folks have found some
|
||||
minor portability glitches and the like, hence this release to fix them.
|
||||
One penalty: slightly reduced compatibility with old compilers, because
|
||||
the ANSI C `unsigned long' type and `ul' constant suffix are used in a
|
||||
few places (I could avoid this but it would be considerably more work).
|
||||
|
||||
New in alpha3.4: The complex bug alluded to below has been fixed (in a
|
||||
slightly kludgey temporary way that may hurt efficiency a bit; this is
|
||||
another "get it out the door for 4.4" release). The tests at the end of
|
||||
the tests file have accordingly been uncommented. The primary sign of
|
||||
the bug was that something like a?b matching ab matched b rather than ab.
|
||||
(The bug was essentially specific to this exact situation, else it would
|
||||
have shown up earlier.)
|
||||
|
||||
New in alpha3.3: The definition of word boundaries has been altered
|
||||
slightly, to more closely match the usual programming notion that "_"
|
||||
is an alphabetic. Stuff used for pre-ANSI systems is now in a subdir,
|
||||
and the makefile no longer alludes to it in mysterious ways. The
|
||||
makefile has generally been cleaned up some. Fixes have been made
|
||||
(again!) so that the regression test will run without -DREDEBUG, at
|
||||
the cost of weaker checking. A workaround for a bug in some folks'
|
||||
<assert.h> has been added. And some more things have been added to
|
||||
tests, including a couple right at the end which are commented out
|
||||
because the code currently flunks them (complex bug; fix coming).
|
||||
Plus the usual minor cleanup.
|
||||
|
||||
New in alpha3.2: Assorted bits of cleanup and portability improvement
|
||||
(the development base is now a BSDI system using GCC instead of an ancient
|
||||
Sun system, and the newer compiler exposed some glitches). Fix for a
|
||||
serious bug that affected REs using many [] (including REG_ICASE REs
|
||||
because of the way they are implemented), *sometimes*, depending on
|
||||
memory-allocation patterns. The header-file prototypes no longer name
|
||||
the parameters, avoiding possible name conflicts. The possibility that
|
||||
some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is
|
||||
now handled gracefully. "uchar" is no longer used as an internal type
|
||||
name (too many people have the same idea). Still the same old lousy
|
||||
performance, alas.
|
||||
|
||||
New in alpha3.1: Basically nothing, this release is just a bookkeeping
|
||||
convenience. Stay tuned.
|
||||
|
||||
New in alpha3.0: Performance is no better, alas, but some fixes have been
|
||||
made and some functionality has been added. (This is basically the "get
|
||||
it out the door in time for 4.4" release.) One bug fix: regfree() didn't
|
||||
free the main internal structure (how embarrassing). It is now possible
|
||||
to put NULs in either the RE or the target string, using (resp.) a new
|
||||
REG_PEND flag and the old REG_STARTEND flag. The REG_NOSPEC flag to
|
||||
regcomp() makes all characters ordinary, so you can match a literal
|
||||
string easily (this will become more useful when performance improves!).
|
||||
There are now primitives to match beginnings and ends of words, although
|
||||
the syntax is disgusting and so is the implementation. The REG_ATOI
|
||||
debugging interface has changed a bit. And there has been considerable
|
||||
internal cleanup of various kinds.
|
||||
|
||||
New in alpha2.3: Split change list out of README, and moved flags notes
|
||||
into Makefile. Macro-ized the name of regex(7) in regex(3), since it has
|
||||
to change for 4.4BSD. Cleanup work in engine.c, and some new regression
|
||||
tests to catch tricky cases thereof.
|
||||
|
||||
New in alpha2.2: Out-of-date manpages updated. Regerror() acquires two
|
||||
small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges
|
||||
in my own test program and might be useful to others for similar purposes.
|
||||
The regression test will now compile (and run) without REDEBUG. The
|
||||
BRE \$ bug is fixed. Most uses of "uchar" are gone; it's all chars now.
|
||||
Char/uchar parameters are now written int/unsigned, to avoid possible
|
||||
portability problems with unpromoted parameters. Some unsigned casts have
|
||||
been introduced to minimize portability problems with shifting into sign
|
||||
bits.
|
||||
|
||||
New in alpha2.1: Lots of little stuff, cleanup and fixes. The one big
|
||||
thing is that regex.h is now generated, using mkh, rather than being
|
||||
supplied in the distribution; due to circularities in dependencies,
|
||||
you have to build regex.h explicitly by "make h". The two known bugs
|
||||
have been fixed (and the regression test now checks for them), as has a
|
||||
problem with assertions not being suppressed in the absence of REDEBUG.
|
||||
No performance work yet.
|
||||
|
||||
New in alpha2: Backslash-anything is an ordinary character, not an
|
||||
error (except, of course, for the handful of backslashed metacharacters
|
||||
in BREs), which should reduce script breakage. The regression test
|
||||
checks *where* null strings are supposed to match, and has generally
|
||||
been tightened up somewhat. Small bug fixes in parameter passing (not
|
||||
harmful, but technically errors) and some other areas. Debugging
|
||||
invoked by defining REDEBUG rather than not defining NDEBUG.
|
||||
|
||||
New in alpha+3: full prototyping for internal routines, using a little
|
||||
helper program, mkh, which extracts prototypes given in stylized comments.
|
||||
More minor cleanup. Buglet fix: it's CHAR_BIT, not CHAR_BITS. Simple
|
||||
pre-screening of input when a literal string is known to be part of the
|
||||
RE; this does wonders for performance.
|
||||
|
||||
New in alpha+2: minor bits of cleanup. Notably, the number "32" for the
|
||||
word width isn't hardwired into regexec.c any more, the public header
|
||||
file prototypes the functions if __STDC__ is defined, and some small typos
|
||||
in the manpages have been fixed.
|
||||
|
||||
New in alpha+1: improvements to the manual pages, and an important
|
||||
extension, the REG_STARTEND option to regexec().

.SH DESCRIPTION
|
||||
These routines implement POSIX 1003.2 regular expressions (``RE''s);
|
||||
see
|
||||
.ZR .
|
||||
.I Regcomp
|
||||
compiles an RE written as a string into an internal form,
|
||||
.I regexec
|
||||
matches that internal form against a string and reports results,
|
||||
.I regerror
|
||||
transforms error codes from either into human-readable messages,
|
||||
and
|
||||
.I regfree
|
||||
frees any dynamically-allocated storage used by the internal form
|
||||
of an RE.
|
||||
.PP
|
||||
The header
|
||||
.I <regex.h>
|
||||
declares two structure types,
|
||||
.I regex_t
|
||||
and
|
||||
.IR regmatch_t ,
|
||||
the former for compiled internal forms and the latter for match reporting.
|
||||
It also declares the four functions,
|
||||
a type
|
||||
.IR regoff_t ,
|
||||
and a number of constants with names starting with ``REG_''.
|
||||
.PP
|
||||
.I Regcomp
|
||||
compiles the regular expression contained in the
|
||||
.I pattern
|
||||
string,
|
||||
subject to the flags in
|
||||
.IR cflags ,
|
||||
and places the results in the
|
||||
.I regex_t
|
||||
structure pointed to by
|
||||
.IR preg .
|
||||
.I Cflags
|
||||
is the bitwise OR of zero or more of the following flags:
|
||||
.IP REG_EXTENDED \w'REG_EXTENDED'u+2n
|
||||
Compile modern (``extended'') REs,
|
||||
rather than the obsolete (``basic'') REs that
|
||||
are the default.
|
||||
.IP REG_BASIC
|
||||
This is a synonym for 0,
|
||||
provided as a counterpart to REG_EXTENDED to improve readability.
|
||||
This is an extension,
|
||||
compatible with but not specified by POSIX 1003.2,
|
||||
and should be used with
|
||||
caution in software intended to be portable to other systems.
|
||||
.IP REG_NOSPEC
|
||||
Compile with recognition of all special characters turned off.
|
||||
All characters are thus considered ordinary,
|
||||
so the ``RE'' is a literal string.
|
||||
This is an extension,
|
||||
compatible with but not specified by POSIX 1003.2,
|
||||
and should be used with
|
||||
caution in software intended to be portable to other systems.
|
||||
REG_EXTENDED and REG_NOSPEC may not be used
|
||||
in the same call to
|
||||
.IR regcomp .
|
||||
.IP REG_ICASE
|
||||
Compile for matching that ignores upper/lower case distinctions.
|
||||
See
|
||||
.ZR .
|
||||
.IP REG_NOSUB
|
||||
Compile for matching that need only report success or failure,
|
||||
not what was matched.
|
||||
.IP REG_NEWLINE
|
||||
Compile for newline-sensitive matching.
|
||||
By default, newline is a completely ordinary character with no special
|
||||
meaning in either REs or strings.
|
||||
With this flag,
|
||||
`[^' bracket expressions and `.' never match newline,
|
||||
a `^' anchor matches the null string after any newline in the string
|
||||
in addition to its normal function,
|
||||
and the `$' anchor matches the null string before any newline in the
|
||||
string in addition to its normal function.
|
||||
.IP REG_PEND
|
||||
The regular expression ends,
|
||||
not at the first NUL,
|
||||
but just before the character pointed to by the
|
||||
.I re_endp
|
||||
member of the structure pointed to by
|
||||
.IR preg .
|
||||
The
|
||||
.I re_endp
|
||||
member is of type
|
||||
.IR const\ char\ * .
|
||||
This flag permits inclusion of NULs in the RE;
|
||||
they are considered ordinary characters.
|
||||
This is an extension,
|
||||
compatible with but not specified by POSIX 1003.2,
|
||||
and should be used with
|
||||
caution in software intended to be portable to other systems.
|
||||
.PP
|
||||
When successful,
|
||||
.I regcomp
|
||||
returns 0 and fills in the structure pointed to by
|
||||
.IR preg .
|
||||
One member of that structure
|
||||
(other than
|
||||
.IR re_endp )
|
||||
is publicized:
|
||||
.IR re_nsub ,
|
||||
of type
|
||||
.IR size_t ,
|
||||
contains the number of parenthesized subexpressions within the RE
|
||||
(except that the value of this member is undefined if the
|
||||
REG_NOSUB flag was used).
|
||||
If
|
||||
.I regcomp
|
||||
fails, it returns a non-zero error code;
|
||||
see DIAGNOSTICS.
|
||||
.PP
|
||||
.I Regexec
|
||||
matches the compiled RE pointed to by
|
||||
.I preg
|
||||
against the
|
||||
.IR string ,
|
||||
subject to the flags in
|
||||
.IR eflags ,
|
||||
and reports results using
|
||||
.IR nmatch ,
|
||||
.IR pmatch ,
|
||||
and the returned value.
|
||||
The RE must have been compiled by a previous invocation of
|
||||
.IR regcomp .
|
||||
The compiled form is not altered during execution of
|
||||
.IR regexec ,
|
||||
so a single compiled RE can be used simultaneously by multiple threads.
|
||||
.PP
|
||||
By default,
|
||||
the NUL-terminated string pointed to by
|
||||
.I string
|
||||
is considered to be the text of an entire line,
|
||||
with the NUL indicating the end of the line.
|
||||
(That is,
|
||||
any other end-of-line marker is considered to have been removed
|
||||
and replaced by the NUL.)
|
||||
The
|
||||
.I eflags
|
||||
argument is the bitwise OR of zero or more of the following flags:
|
||||
.IP REG_NOTBOL \w'REG_STARTEND'u+2n
|
||||
The first character of
|
||||
the string
|
||||
is not the beginning of a line, so the `^' anchor should not match before it.
|
||||
This does not affect the behavior of newlines under REG_NEWLINE.
|
||||
.IP REG_NOTEOL
|
||||
The NUL terminating
|
||||
the string
|
||||
does not end a line, so the `$' anchor should not match before it.
|
||||
This does not affect the behavior of newlines under REG_NEWLINE.
|
||||
.IP REG_STARTEND
|
||||
The string is considered to start at
|
||||
\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_so\fR
|
||||
and to have a terminating NUL located at
|
||||
\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_eo\fR
|
||||
(there need not actually be a NUL at that location),
|
||||
regardless of the value of
|
||||
.IR nmatch .
|
||||
See below for the definition of
|
||||
.IR pmatch
|
||||
and
|
||||
.IR nmatch .
|
||||
This is an extension,
|
||||
compatible with but not specified by POSIX 1003.2,
|
||||
and should be used with
|
||||
caution in software intended to be portable to other systems.
|
||||
Note that a non-zero \fIrm_so\fR does not imply REG_NOTBOL;
|
||||
REG_STARTEND affects only the location of the string,
|
||||
not how it is matched.
|
||||
.PP
|
||||
See
|
||||
.ZR
|
||||
for a discussion of what is matched in situations where an RE or a
|
||||
portion thereof could match any of several substrings of
|
||||
.IR string .
|
||||
.PP
|
||||
Normally,
|
||||
.I regexec
|
||||
returns 0 for success and the non-zero code REG_NOMATCH for failure.
|
||||
Other non-zero error codes may be returned in exceptional situations;
|
||||
see DIAGNOSTICS.
|
||||
.PP
|
||||
If REG_NOSUB was specified in the compilation of the RE,
|
||||
or if
|
||||
.I nmatch
|
||||
is 0,
|
||||
.I regexec
|
||||
ignores the
|
||||
.I pmatch
|
||||
argument (but see below for the case where REG_STARTEND is specified).
|
||||
Otherwise,
|
||||
.I pmatch
|
||||
points to an array of
|
||||
.I nmatch
|
||||
structures of type
|
||||
.IR regmatch_t .
|
||||
Such a structure has at least the members
|
||||
.I rm_so
|
||||
and
|
||||
.IR rm_eo ,
|
||||
both of type
|
||||
.I regoff_t
|
||||
(a signed arithmetic type at least as large as an
|
||||
.I off_t
|
||||
and a
|
||||
.IR ssize_t ),
|
||||
containing respectively the offset of the first character of a substring
|
||||
and the offset of the first character after the end of the substring.
|
||||
Offsets are measured from the beginning of the
|
||||
.I string
|
||||
argument given to
|
||||
.IR regexec .
|
||||
An empty substring is denoted by equal offsets,
|
||||
both indicating the character following the empty substring.
|
||||
.PP
|
||||
The 0th member of the
|
||||
.I pmatch
|
||||
array is filled in to indicate what substring of
|
||||
.I string
|
||||
was matched by the entire RE.
|
||||
Remaining members report what substring was matched by parenthesized
|
||||
subexpressions within the RE;
|
||||
member
|
||||
.I i
|
||||
reports subexpression
|
||||
.IR i ,
|
||||
with subexpressions counted (starting at 1) by the order of their opening
|
||||
parentheses in the RE, left to right.
|
||||
Unused entries in the array\(emcorresponding either to subexpressions that
|
||||
did not participate in the match at all, or to subexpressions that do not
|
||||
exist in the RE (that is, \fIi\fR\ > \fIpreg\fR\->\fIre_nsub\fR)\(emhave both
|
||||
.I rm_so
|
||||
and
|
||||
.I rm_eo
|
||||
set to \-1.
|
||||
If a subexpression participated in the match several times,
|
||||
the reported substring is the last one it matched.
|
||||
(Note, as an example in particular, that when the RE `(b*)+' matches `bbb',
|
||||
the parenthesized subexpression matches the three `b's and then
|
||||
an infinite number of empty strings following the last `b',
|
||||
so the reported substring is one of the empties.)
|
||||
.PP
|
||||
If REG_STARTEND is specified,
|
||||
.I pmatch
|
||||
must point to at least one
|
||||
.I regmatch_t
|
||||
(even if
|
||||
.I nmatch
|
||||
is 0 or REG_NOSUB was specified),
|
||||
to hold the input offsets for REG_STARTEND.
|
||||
Use for output is still entirely controlled by
|
||||
.IR nmatch ;
|
||||
if
|
||||
.I nmatch
|
||||
is 0 or REG_NOSUB was specified,
|
||||
the value of
|
||||
.IR pmatch [0]
|
||||
will not be changed by a successful
|
||||
.IR regexec .
|
||||
.PP
|
||||
.I Regerror
|
||||
maps a non-zero
|
||||
.I errcode
|
||||
from either
|
||||
.I regcomp
|
||||
or
|
||||
.I regexec
|
||||
to a human-readable, printable message.
|
||||
If
|
||||
.I preg
|
||||
is non-NULL,
|
||||
the error code should have arisen from use of
|
||||
the
|
||||
.I regex_t
|
||||
pointed to by
|
||||
.IR preg ,
|
||||
and if the error code came from
|
||||
.IR regcomp ,
|
||||
it should have been the result from the most recent
|
||||
.I regcomp
|
||||
using that
|
||||
.IR regex_t .
|
||||
.RI ( Regerror
|
||||
may be able to supply a more detailed message using information
|
||||
from the
|
||||
.IR regex_t .)
|
||||
.I Regerror
|
||||
places the NUL-terminated message into the buffer pointed to by
|
||||
.IR errbuf ,
|
||||
limiting the length (including the NUL) to at most
|
||||
.I errbuf_size
|
||||
bytes.
|
||||
If the whole message won't fit,
|
||||
as much of it as will fit before the terminating NUL is supplied.
|
||||
In any case,
|
||||
the returned value is the size of buffer needed to hold the whole
|
||||
message (including terminating NUL).
|
||||
If
|
||||
.I errbuf_size
|
||||
is 0,
|
||||
.I errbuf
|
||||
is ignored but the return value is still correct.
|
||||
.PP
|
||||
If the
|
||||
.I errcode
|
||||
given to
|
||||
.I regerror
|
||||
is first ORed with REG_ITOA,
|
||||
the ``message'' that results is the printable name of the error code,
|
||||
e.g. ``REG_NOMATCH'',
|
||||
rather than an explanation thereof.
|
||||
If
|
||||
.I errcode
|
||||
is REG_ATOI,
|
||||
then
|
||||
.I preg
|
||||
shall be non-NULL and the
|
||||
.I re_endp
|
||||
member of the structure it points to
|
||||
must point to the printable name of an error code;
|
||||
in this case, the result in
|
||||
.I errbuf
|
||||
is the decimal digits of
|
||||
the numeric value of the error code
|
||||
(0 if the name is not recognized).
|
||||
REG_ITOA and REG_ATOI are intended primarily as debugging facilities;
|
||||
they are extensions,
|
||||
compatible with but not specified by POSIX 1003.2,
|
||||
and should be used with
|
||||
caution in software intended to be portable to other systems.
|
||||
Be warned also that they are considered experimental and changes are possible.
|
||||
.PP
|
||||
.I Regfree
|
||||
frees any dynamically-allocated storage associated with the compiled RE
|
||||
pointed to by
|
||||
.IR preg .
|
||||
The remaining
|
||||
.I regex_t
|
||||
is no longer a valid compiled RE
|
||||
and the effect of supplying it to
|
||||
.I regexec
|
||||
or
|
||||
.I regerror
|
||||
is undefined.
|
||||
.PP
|
||||
None of these functions references global variables except for tables
|
||||
of constants;
|
||||
all are safe for use from multiple threads if the arguments are safe.
|
||||
.SH IMPLEMENTATION CHOICES
|
||||
There are a number of decisions that 1003.2 leaves up to the implementor,
|
||||
either by explicitly saying ``undefined'' or by virtue of them being
|
||||
forbidden by the RE grammar.
|
||||
This implementation treats them as follows.
|
||||
.PP
|
||||
See
|
||||
.ZR
|
||||
for a discussion of the definition of case-independent matching.
|
||||
.PP
|
||||
There is no particular limit on the length of REs,
|
||||

.SH BUGS
|

This is an alpha release with known defects.
|
||||
Please report problems.
|
||||
.PP
|
||||
There is one known functionality bug.
|
||||
The implementation of internationalization is incomplete:
|
||||
the locale is always assumed to be the default one of 1003.2,
|
||||
and only the collating elements etc. of that locale are available.
|
||||
.PP
|
||||
The back-reference code is subtle and doubts linger about its correctness
|
||||
in complex cases.
|
||||
.PP
|
||||
.I Regexec
|
||||
performance is poor.
|
||||
This will improve with later releases.
|
||||
.I Nmatch
|
||||
exceeding 0 is expensive;
|
||||
.I nmatch
|
||||
exceeding 1 is worse.
|
||||
.I Regexec
|
||||
is largely insensitive to RE complexity \fIexcept\fR that back
|
||||
references are massively expensive.
|
||||
RE length does matter; in particular, there is a strong speed bonus
|
||||
for keeping RE length under about 30 characters,
|
||||
with most special characters counting roughly double.
|
||||
.PP
|
||||
.I Regcomp
|
||||
implements bounded repetitions by macro expansion,
|
||||
which is costly in time and space if counts are large
|
||||
or bounded repetitions are nested.
|
||||
An RE like, say,
|
||||
`((((a{1,100}){1,100}){1,100}){1,100}){1,100}'
|
||||
will (eventually) run almost any existing machine out of swap space.
|
||||
.PP
|
||||
There are suspected problems with response to obscure error conditions.
|
||||
Notably,
|
||||
certain kinds of internal overflow,
|
||||
produced only by truly enormous REs or by multiply nested bounded repetitions,
|
||||
are probably not handled well.
|
||||
.PP
|
||||
Due to a mistake in 1003.2, things like `a)b' are legal REs because `)' is
|
||||
a special character only in the presence of a previous unmatched `('.
|
||||
This can't be fixed until the spec is fixed.
|
||||
.PP
|
||||
The standard's definition of back references is vague.
|
||||
For example, does
|
||||
`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?
|
||||
Until the standard is clarified,
|
||||
behavior in such cases should not be relied on.
|
||||
.PP
|
||||
The implementation of word-boundary matching is a bit of a kludge,
|
||||
and bugs may lurk in combinations of word-boundary matching and anchoring.

.BY "Henry Spencer"
|
||||
.SH NAME
|
||||
regex \- POSIX 1003.2 regular expressions
|
||||
.SH DESCRIPTION
|
||||
Regular expressions (``RE''s),
|
||||
as defined in POSIX 1003.2, come in two forms:
|
||||
modern REs (roughly those of
|
||||
.IR egrep ;
|
||||
1003.2 calls these ``extended'' REs)
|
||||
and obsolete REs (roughly those of
|
||||
.IR ed ;
|
||||
1003.2 ``basic'' REs).
|
||||
Obsolete REs mostly exist for backward compatibility in some old programs;
|
||||
they will be discussed at the end.
|
||||
1003.2 leaves some aspects of RE syntax and semantics open;
|
||||
`\(dg' marks decisions on these aspects that
|
||||
may not be fully portable to other 1003.2 implementations.
|
||||
.PP
|
||||
A (modern) RE is one\(dg or more non-empty\(dg \fIbranches\fR,
|
||||
separated by `|'.
|
||||
It matches anything that matches one of the branches.
|
||||
.PP
|
||||
A branch is one\(dg or more \fIpieces\fR, concatenated.
|
||||
It matches a match for the first, followed by a match for the second, etc.
|
||||
.PP
|
||||
A piece is an \fIatom\fR possibly followed
|
||||
by a single\(dg `*', `+', `?', or \fIbound\fR.
|
||||
An atom followed by `*' matches a sequence of 0 or more matches of the atom.
|
||||
An atom followed by `+' matches a sequence of 1 or more matches of the atom.
|
||||
An atom followed by `?' matches a sequence of 0 or 1 matches of the atom.
|
||||
.PP
|
||||
A \fIbound\fR is `{' followed by an unsigned decimal integer,
|
||||
possibly followed by `,'
|
||||
possibly followed by another unsigned decimal integer,
|
||||
always followed by `}'.
|
||||
The integers must lie between 0 and RE_DUP_MAX (255\(dg) inclusive,
|
||||
and if there are two of them, the first may not exceed the second.
|
||||
An atom followed by a bound containing one integer \fIi\fR
|
||||
and no comma matches
|
||||
a sequence of exactly \fIi\fR matches of the atom.
|
||||
An atom followed by a bound
|
||||
containing one integer \fIi\fR and a comma matches
|
||||
a sequence of \fIi\fR or more matches of the atom.
|
||||
An atom followed by a bound
|
||||
containing two integers \fIi\fR and \fIj\fR matches
|
||||
a sequence of \fIi\fR through \fIj\fR (inclusive) matches of the atom.
|
||||
.PP
|
||||
An atom is a regular expression enclosed in `()' (matching a match for the
|
||||
regular expression),
|
||||
an empty set of `()' (matching the null string)\(dg,
|
||||
a \fIbracket expression\fR (see below), `.'
|
||||
(matching any single character), `^' (matching the null string at the
|
||||
beginning of a line), `$' (matching the null string at the
|
||||
end of a line), a `\e' followed by one of the characters
|
||||
`^.[$()|*+?{\e'
|
||||
(matching that character taken as an ordinary character),
|
||||
a `\e' followed by any other character\(dg
|
||||
(matching that character taken as an ordinary character,
|
||||
as if the `\e' had not been present\(dg),
|
||||
or a single character with no other significance (matching that character).
|
||||
A `{' followed by a character other than a digit is an ordinary
|
||||
character, not the beginning of a bound\(dg.
|
||||
It is illegal to end an RE with `\e'.
|
||||
.PP
|
||||
A \fIbracket expression\fR is a list of characters enclosed in `[]'.
|
||||
It normally matches any single character from the list (but see below).
|
||||
If the list begins with `^',
|
||||
it matches any single character
|
||||
(but see below) \fInot\fR from the rest of the list.
|
||||
If two characters in the list are separated by `\-', this is shorthand
|
||||
for the full \fIrange\fR of characters between those two (inclusive) in the
|
||||
collating sequence,
|
||||
e.g. `[0\-9]' in ASCII matches any decimal digit.
|
||||
It is illegal\(dg for two ranges to share an
|
||||
endpoint, e.g. `a\-c\-e'.
|
||||
Ranges are very collating-sequence-dependent,
|
||||
and portable programs should avoid relying on them.
|
||||
.PP
|
||||
To include a literal `]' in the list, make it the first character
|
||||
(following a possible `^').
|
||||
To include a literal `\-', make it the first or last character,
|
||||
or the second endpoint of a range.
|
||||
To use a literal `\-' as the first endpoint of a range,
|
||||
enclose it in `[.' and `.]' to make it a collating element (see below).
|
||||
With the exception of these and some combinations using `[' (see next
|
||||
paragraphs), all other special characters, including `\e', lose their
|
||||
special significance within a bracket expression.
|
||||
.PP
|
||||
Within a bracket expression, a collating element (a character,
|
||||
a multi-character sequence that collates as if it were a single character,
|
||||
or a collating-sequence name for either)
|
||||
enclosed in `[.' and `.]' stands for the
|
||||
sequence of characters of that collating element.
|
||||
The sequence is a single element of the bracket expression's list.
|
||||
A bracket expression containing a multi-character collating element
|
||||
can thus match more than one character,
|
||||
e.g. if the collating sequence includes a `ch' collating element,
|
||||
then the RE `[[.ch.]]*c' matches the first five characters
|
||||
of `chchcc'.
|
||||
.PP
|
||||
Within a bracket expression, a collating element enclosed in `[=' and
|
||||
`=]' is an equivalence class, standing for the sequences of characters
|
||||
of all collating elements equivalent to that one, including itself.
|
||||
(If there are no other equivalent collating elements,
|
||||
the treatment is as if the enclosing delimiters were `[.' and `.]'.)
|
||||
For example, if o and \o'o^' are the members of an equivalence class,
|
||||
then `[[=o=]]', `[[=\o'o^'=]]', and `[o\o'o^']' are all synonymous.
|
||||
An equivalence class may not\(dg be an endpoint
|
||||
of a range.
|
||||
.PP
|
||||
Within a bracket expression, the name of a \fIcharacter class\fR enclosed
|
||||
in `[:' and `:]' stands for the list of all characters belonging to that
|
||||
class.
|
||||
Standard character class names are:
|
||||
.PP
|
||||
.RS
|
||||
.nf
|
||||
.ta 3c 6c 9c
|

||||
blank lower upper
|
||||

|
||||
.fi
|
||||
.RE
|
||||
.PP
|
||||
These stand for the character classes defined in
|
||||
.IR ctype (3).
|
||||
A locale may provide others.
|
||||
A character class may not be used as an endpoint of a range.
|
||||
.PP
|
||||
There are two special cases\(dg of bracket expressions:
|
||||
the bracket expressions `[[:<:]]' and `[[:>:]]' match the null string at
|
||||
the beginning and end of a word respectively.
|
||||
A word is defined as a sequence of
|
||||
word characters
|
||||
which is neither preceded nor followed by
|
||||
word characters.
|
||||
A word character is an
|
||||
.I alnum
|
||||
character (as defined by
|
||||
.IR ctype (3))
|
||||
or an underscore.
|
||||
This is an extension,
|
||||
compatible with but not specified by POSIX 1003.2,
|
||||
and should be used with
|
||||
caution in software intended to be portable to other systems.
|
||||
.PP
|
||||
In the event that an RE could match more than one substring of a given
|
||||
string,
|
||||
the RE matches the one starting earliest in the string.
|
||||
If the RE could match more than one substring starting at that point,
|
||||
it matches the longest.
|
||||
Subexpressions also match the longest possible substrings, subject to
|
||||
the constraint that the whole match be as long as possible,
|
||||
with subexpressions starting earlier in the RE taking priority over
|
||||
ones starting later.
|
||||
Note that higher-level subexpressions thus take priority over
|
||||
their lower-level component subexpressions.
|
||||
.PP
|
||||
Match lengths are measured in characters, not collating elements.
|
||||
A null string is considered longer than no match at all.
|
||||
For example,
|
||||
`bb*' matches the three middle characters of `abbbc',
|
||||
`(wee|week)(knights|nights)' matches all ten characters of `weeknights',
|
||||
when `(.*).*' is matched against `abc' the parenthesized subexpression
|
||||
matches all three characters, and
|
||||
when `(a*)*' is matched against `bc' both the whole RE and the parenthesized
|
||||
subexpression match the null string.
|
||||
.PP
|
||||
If case-independent matching is specified,
|
||||
the effect is much as if all case distinctions had vanished from the
|
||||
alphabet.
|
||||
When an alphabetic that exists in multiple cases appears as an
|
||||
ordinary character outside a bracket expression, it is effectively
|
||||
transformed into a bracket expression containing both cases,
|
||||
e.g. `x' becomes `[xX]'.
|
||||
When it appears inside a bracket expression, all case counterparts
|
||||
of it are added to the bracket expression, so that (e.g.) `[x]'
|
||||
becomes `[xX]' and `[^x]' becomes `[^xX]'.
|
||||
.PP
|
||||
No particular limit is imposed on the length of REs\(dg.
|
||||
Programs intended to be portable should not employ REs longer
|
||||
than 256 bytes,
|
||||
as an implementation can refuse to accept such REs and remain
|
||||
POSIX-compliant.
|
||||
.PP
|
||||
Obsolete (``basic'') regular expressions differ in several respects.
|
||||
`|', `+', and `?' are ordinary characters and there is no equivalent
|
||||
for their functionality.
|
||||
The delimiters for bounds are `\e{' and `\e}',
|
||||
with `{' and `}' by themselves ordinary characters.
|
||||
The parentheses for nested subexpressions are `\e(' and `\e)',
|
||||
with `(' and `)' by themselves ordinary characters.
|
||||
`^' is an ordinary character except at the beginning of the
|
||||
RE or\(dg the beginning of a parenthesized subexpression,
|
||||
`$' is an ordinary character except at the end of the
|
||||
RE or\(dg the end of a parenthesized subexpression,
|
||||
and `*' is an ordinary character if it appears at the beginning of the
|
||||
RE or the beginning of a parenthesized subexpression
|
||||
(after a possible leading `^').
|
||||
Finally, there is one new type of atom, a \fIback reference\fR:
|
||||
`\e' followed by a non-zero decimal digit \fId\fR
|
||||
matches the same sequence of characters
|
||||
matched by the \fId\fRth parenthesized subexpression
|
||||
(numbering subexpressions by the positions of their opening parentheses,
|
||||
left to right),
|
||||
so that (e.g.) `\e([bc]\e)\e1' matches `bb' or `cc' but not `bc'.
