<p>

Boost-Extended format strings treat all characters as literals except for
|
||||
'$', '\', '(', ')', '?', and ':'.

<a name="id525164"></a>
|
||||
<a href="boost_format_syntax.html#boost_regex.format.boost_format_syntax.grouping">Grouping</a>
|
||||
</h5>
|
||||
<p>
|
||||
The characters '(' and ')' perform lexical grouping, so use \( and \) if
|
||||
you want a to output literal parenthesis.

<a name="id525196"></a>
|
||||
<a href="boost_format_syntax.html#boost_regex.format.boost_format_syntax.conditionals">Conditionals</a>
|
||||
</h5>
|
||||
<p>
|
||||
The character '?' begins a conditional expression, the general form is:
|
||||
</p>
|
||||
<p>
|
||||
?Ntrue-expression:false-expression
|
||||
</p>
|
||||
<p>
|
||||
where N is decimal digit.
|
||||
</p>
|
||||
<p>
|
||||
If sub-expression N was matched, then true-expression is evaluated and sent
|
||||
to output, otherwise false-expression is evaluated and sent to output.
|
||||
</p>
|
||||
<p>
|
||||
You will normally need to surround a conditional-expression with parenthesis
|
||||
in order to prevent ambiguities.
|
||||
</p>
|
||||
<p>
|
||||
For example, the format string "(?1foo:bar)" will replace each
|
||||
match found with "foo" if the sub-expression $1 was matched, and
|
||||
with "bar" otherwise.
