- <section>
- <title>Regular Expressions</title>
- <p>The regular expressions allowed here is a subset of the set found
- in <c>egrep</c> and in the <c>AWK</c> programming language, as
- defined in the book, <c>The AWK Programming Language, by A. V. Aho, B. W. Kernighan, P. J. Weinberger</c>. They are
- composed of the following characters:</p>
- <taglist>
- <tag>c</tag>
- <item>
- <p>matches the non-metacharacter <c>c</c>.</p>
- </item>
- <tag>\c</tag>
- <item>
- <p>matches the escape sequence or literal character <c>c</c>.</p>
- </item>
- <tag>.</tag>
- <item>
- <p>matches any character.</p>
- </item>
- <tag>^</tag>
- <item>
- <p>matches the beginning of a string.</p>
- </item>
- <tag>$</tag>
- <item>
- <p>matches the end of a string.</p>
- </item>
- <tag>[abc...]</tag>
- <item>
- <p>character class, which matches any of the characters
- <c>abc...</c> Character ranges are specified by a pair of
- characters separated by a <c>-</c>.</p>
- </item>
- <tag>[^abc...]</tag>
- <item>
- <p>negated character class, which matches any character except
- <c>abc...</c>.</p>
- </item>
- <tag>r1 | r2</tag>
- <item>
- <p>alternation. It matches either <c>r1</c> or <c>r2</c>.</p>
- </item>
- <tag>r1r2</tag>
- <item>
- <p>concatenation. It matches <c>r1</c> and then <c>r2</c>.</p>
- </item>
- <tag>r+</tag>
- <item>
- <p>matches one or more <c>r</c>s.</p>
- </item>
- <tag>r*</tag>
- <item>
- <p>matches zero or more <c>r</c>s.</p>
- </item>
- <tag>r?</tag>
- <item>
- <p>matches zero or one <c>r</c>s.</p>
- </item>
- <tag>(r)</tag>
- <item>
- <p>grouping. It matches <c>r</c>.</p>
- </item>
- </taglist>
- <p>The escape sequences allowed are the same as for Erlang
- strings:</p>
- <taglist>
- <tag><c>\b</c></tag>
- <item>
- <p>backspace</p>
- </item>
- <tag><c>\f</c></tag>
- <item>
- <p>form feed </p>
- </item>
- <tag><c>\n</c></tag>
- <item>
- <p>newline (line feed) </p>
- </item>
- <tag><c>\r</c></tag>
- <item>
- <p>carriage return </p>
- </item>
- <tag><c>\t</c></tag>
- <item>
- <p>tab </p>
- </item>
- <tag><c>\e</c></tag>
- <item>
- <p>escape </p>
- </item>
- <tag><c>\v</c></tag>
- <item>
- <p>vertical tab </p>
- </item>
- <tag><c>\s</c></tag>
- <item>
- <p>space </p>
- </item>
- <tag><c>\d</c></tag>
- <item>
- <p>delete </p>
- </item>
- <tag><c>\ddd</c></tag>
- <item>
- <p>the octal value ddd </p>
- </item>
- <tag><c>\xhh</c></tag>
- <item>
- <p>The hexadecimal value <c>hh</c>.</p>
- </item>
- <tag><c>\x{h...}</c></tag>
- <item>
- <p>The hexadecimal value <c>h...</c>.</p>
- </item>
- <tag><c>\c</c></tag>
- <item>
- <p>any other character literally, for example <c>\\</c> for backslash,
- <c>\"</c> for ")</p>
- </item>
- </taglist>
- <p>To make these functions easier to use, in combination with the
- function <c>io:get_line</c> which terminates the input line with
- a new line, the <c>$</c> characters also matches a string ending
- with <c>"...\n"</c>. The following examples
- define Erlang data types:</p>
- <pre>
-Atoms [a-z][0-9a-zA-Z_]*
-
-Variables [A-Z_][0-9a-zA-Z_]*
-
-Floats (\+|-)?[0-9]+\.[0-9]+((E|e)(\+|-)?[0-9]+)?</pre>
- <p>Regular expressions are written as Erlang strings when used with the functions in this module. This means that any <c>\</c> or <c>"</c> characters in a regular expression
- string must be written with <c>\</c> as they are also escape characters for the string. For example, the regular expression string for Erlang floats is:
- <c>"(\\+|-)?[0-9]+\\.[0-9]+((E|e)(\\+|-)?[0-9]+)?"</c>.</p>
- <p>It is not really necessary to have the escape sequences as part of the regular expression syntax as they can always be generated directly in the string. They are included for completeness and can they can also be useful when generating regular expressions, or when they are entered other than with Erlang strings.</p>
