<p>

The high level wrapper class RegEx is now deprecated and does not form
|
||||
part of the regular expression standardization proposal. This type still
|
||||
exists, and existing code will continue to compile, however the following
|
||||
documentation is unlikely to be further updated.

|
||||
<p>
|
||||
The class RegEx provides a high level simplified interface to the regular
|
||||
expression library, this class only handles narrow character strings, and
|
||||
regular expressions always follow the "normal" syntax - that
|
||||
is the same as the perl / ECMAScript synatx.

<p>

The parameters for the primary version of <code class="computeroutput"><span class="identifier">regex_grep</span></code>
|
||||
have the following meanings:
|
||||
</p>
|
||||
<p>
|
||||
foo: A predicate function object or function pointer, see below for more
|
||||
information.
|
||||
</p>
|
||||
<p>
|
||||
first: The start of the range to search.
|
||||
</p>
|
||||
<p>
|
||||
last: The end of the range to search.
|
||||
</p>
|
||||
<p>
|
||||
e: The regular expression to search for.
|
||||
</p>
|
||||
<p>
|
||||
flags: The flags that determine how matching is carried out, one of the
|
||||
match_flags enumerators.
|
||||
</p>
|
||||
<p>
|
||||
The algorithm finds all of the non-overlapping matches of the expression
|
||||
<span class="emphasis"><em>e</em></span>, for each match it fills a <code class="computeroutput"><span class="identifier">match_results</span><span class="special"><</span><span class="identifier">iterator</span><span class="special">></span></code> structure, which contains information
|
||||
on what matched, and calls the predicate <span class="emphasis"><em>foo</em></span>, passing
|
||||
the <code class="computeroutput"><span class="identifier">match_results</span><span class="special"><</span><span class="identifier">iterator</span><span class="special">></span></code>
|
||||
as a single argument. If the predicate returns <span class="emphasis"><em>true</em></span>,
|
||||
then the grep operation continues, otherwise it terminates without searching
|
||||
for further matches. The function returns the number of matches found.
|
||||
</p>
|
||||
<p>
|
||||
The general form of the predicate is:
|
||||
</p>
|
||||
<pre class="programlisting">
|
||||
<span class="keyword">struct</span> <span class="identifier">grep_predicate</span>
|
||||
<span class="special">{</span>
|
||||
<span class="keyword">bool</span> <span class="keyword">operator</span><span class="special">()(</span><span class="keyword">const</span> <span class="identifier">match_results</span><span class="special"><</span><span class="identifier">iterator_type</span><span class="special">>&</span> <span class="identifier">m</span><span class="special">);</span>
|
||||
<span class="special">};</span>
|
||||
</pre>
|
||||
<p>
|
||||
For example the regular expression "a*b" would find one match
|
||||
in the string "aaaaab" and two in the string "aaabb".
|
||||
</p>
|
||||
<p>
|
||||
Remember this algorithm can be used for a lot more than implementing a
|
||||
version of grep, the predicate can be and do anything that you want, grep
|
||||
utilities would output the results to the screen, another program could
|
||||
index a file based on a regular expression and store a set of bookmarks
|
||||
in a list, or a text file conversion utility would output to file. The
|
||||
results of one <code class="computeroutput"><span class="identifier">regex_grep</span></code>
|
||||
can even be chained into another <code class="computeroutput"><span class="identifier">regex_grep</span></code>
|
||||
to create recursive parsers.
|
||||
</p>
|
||||
<p>
|
||||
The algorithm may throw <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">runtime_error</span></code>
|
||||
if the complexity of matching the expression against an <span class="emphasis"><em>N</em></span>
|
||||
character string begins to exceed O(N<sup>2</sup>), or if the program runs out of
|
||||
stack space while matching the expression (if Boost.Regex is configured
|
||||
in recursive mode), or if the matcher exhausts it's permitted memory allocation
|
||||
(if Boost.Regex is configured in non-recursive mode).

||||

in favor of the iterator <a href="../regex_token_iterator.html" title="regex_token_iterator"><code class="computeroutput"><span class="identifier">regex_token_iterator</span></code></a> which has

a more flexible and powerful interface, as well as following the more usual

<span class="bold"><strong>Effects</strong></span>: Each version of the algorithm

takes an output-iterator for output, and a string for input. If the expression

contains no marked sub-expressions, then the algorithm writes one string

onto the output-iterator for each section of input that does not match
|

the expression. If the expression does contain marked sub-expressions,
|

then each time a match is found, one string for each marked sub-expression

will be written to the output-iterator. No more than max_split strings

will be written to the output-iterator. Before returning, all the input
|
||||
processed will be deleted from the string <span class="emphasis"><em>s</em></span> (if <span class="emphasis"><em>max_split</em></span>
|
||||
is not reached then all of <span class="emphasis"><em>s</em></span> will be deleted). Returns
|
||||
the number of strings written to the output-iterator. If the parameter
|
||||
<span class="emphasis"><em>max_split</em></span> is not specified then it defaults to <code class="computeroutput"><span class="identifier">UINT_MAX</span></code>. If no expression is specified,
|
||||
then it defaults to "\s+", and splitting occurs on whitespace.

|
||||
if the complexity of matching the expression against an N character string
|
||||
begins to exceed O(N<sup>2</sup>), or if the program runs out of stack space while
|
||||
matching the expression (if Boost.Regex is configured in recursive mode),
|
||||
or if the matcher exhausts it's permitted memory allocation (if Boost.Regex
|
||||
is configured in non-recursive mode).
