- match keyword lists. As long as one of the keywords specified through the

- parsing input as long as the one of the keywords and it's associated parser
- succeed. Writing : (kwd("k1")[a] / kwd("k2")[b] / ...
- ) is equivalent to: *( "k1" > a | "k2" > b ...

- The keyword list parser works tightly with the kwd, ikwd, dkwd and idkwd

- you of any mistakes. This parser collects all the kwd directives and
- extracts the keyword literals or parsers from the directives to internaly
- build a Ternary Search Tree (TST) and permutation loop (for complex parsers)
- to effectively parse the keywords. Because you can't mix character types
- inside a TST you must take care not to mix wide strings with normal strings
- in the keywords you supply to a keyword list. Should it happen the compiler
- will trap the mistake for you.

- The code above will print:
- </p>
- <pre class="programlisting">Person : John, 10, 1.69
- Person : Mary, 10, 1.69
- Person : Mike, 10, 1.69
- </pre>
- <p>
- Now let's delcare a parser with some occurrence constraints:
- </p>
- <p>
- The parser definition below uses the kwd directive occurrence constraint
- variants to make sure that the name and age keyword occur only once and
- allows the favorite color entry to appear 0 or more times.
- </p>
- <p>
- </p>
- <pre class="programlisting"><span class="identifier">constraint_person_rule</span> <span class="special">%=</span>
- <span class="identifier">kwd</span><span class="special">(</span><span class="string">"name"</span><span class="special">,</span><span class="number">1</span><span class="special">)</span> <span class="special">[</span><span class="char">'='</span> <span class="special">></span> <span class="identifier">parse_string</span> <span class="special">]</span>
- <span class="special">/</span> <span class="identifier">kwd</span><span class="special">(</span><span class="string">"age"</span> <span class="special">,</span><span class="number">1</span><span class="special">)</span> <span class="special">[</span><span class="char">'='</span> <span class="special">></span> <span class="identifier">int_</span><span class="special">]</span>

- <span class="special">;</span>
- </pre>
- <p>
- </p>
- <p>
- And see how it works in these two cases:
- </p>
- <p>
- </p>
- <pre class="programlisting"> <span class="comment">// Here all the give constraint are resepected : parsing will succeed.</span>
- <span class="identifier">test_phrase_parser_attr</span><span class="special">(</span>
- <span class="string">"name = \"Hellen\" \n age = 10 \n size = 1.80m \n favorite color = \"blue\" \n favorite color = \"green\" "</span>
- <span class="special">,</span><span class="identifier">constraint_person_rule</span>
- <span class="special">,</span><span class="identifier">Hellen</span><span class="special">);</span>
- <span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span><span class="special"><<</span><span class="identifier">Hellen</span><span class="special">;</span>
- <span class="comment">// Parsing this string will fail because the age and size minimum occurrence requirements aren't met.</span>
- <span class="identifier">test_phrase_parser_attr</span><span class="special">(</span>
- <span class="string">"name = \"Johny\" \n favorite color = \"blue\" \n favorite color = \"green\" "</span>
- <span class="special">,</span><span class="identifier">constraint_person_rule</span>
- <span class="special">,</span><span class="identifier">Johny</span> <span class="special">);</span>
- </pre>
- <p>
- </p>
- <p>
- Parsing the first string will succeed but fail for the second string as
- the occurrence constraints aren't met. This code should print:
- </p>
- <pre class="programlisting">Person : Hellen, 10, 1.8
- blue
- green
