Format strings are used by the algorithm < a class = "link" href = "ref/regex_replace.html" title = "regex_replace" > < code class = "computeroutput" > < span class = "identifier" > regex_replace< / span > < / code > < / a > and by < a class = "link" href = "ref/match_results.html#boost_regex.match_results_format" > < code class = "computeroutput" > < span class = "identifier" > match_results< / span > < span class = "special" > < > ::< / span > < span class = "identifier" > format< / span > < / code > < / a > , and are used to transform
2007-06-08 09:23:23 +00:00
one string into another.

There are three kind of format string: < a class = "link" href = "format/sed_format.html" title = "Sed Format String Syntax" > Sed< / a > ,
< a class = "link" href = "format/perl_format.html" title = "Perl Format String Syntax" > Perl< / a > and < a class = "link" href = "format/boost_format_syntax.html" title = "Boost-Extended Format String Syntax" > Boost-Extended< / a > .
2007-06-08 09:23:23 +00:00
< / p >
< p >
2007-12-14 10:11:21 +00:00
Alternatively, when the flag < code class = "computeroutput" > < span class = "identifier" > format_literal< / span > < / code >
2007-06-08 09:23:23 +00:00
is passed to one of these functions, then the format string is treated as a
string literal, and is copied unchanged to the output.
