2 // example custom verb that compiles to a <cfcase> tag
3 // usage:
4 // 1. add the lexicon declaration to your circuit file:
5 // <circuit xmlns:cf="cf/">
6 // 2. use the verb in a fuseaction:
7 // <cf:switch expression="#someExpr#">
8 // <cf:case value="someValue">
9 // ... some code ...
10 // </cf:catch>
11 // <cf:case value="anotherValue|andAnother" delimiters="|">
12 // ... more code ...
13 // </cf:case>
14 // <cf:defaultcase>
15 // ... default code ...
16 // </cf:defaultcase>
17 // </cf:switch>
18 //
19 // how this works:
20 // a. validate the attributes passed in (fb_.verbInfo.attributes)
21 // b. in start mode, generate the required CFML
22 // c. in end mode, generate the required CFML
23 //
24 if (fb_.verbInfo.executionMode is "start") {
25 //
26 // validate attributes:
27 // parent tag must be a switch verb in the same lexicon:
28 if (not structKeyExists(fb_.verbInfo,"parent") or
29 fb_.verbInfo.parent.lexicon is not fb_.verbInfo.lexicon or
30 fb_.verbInfo.parent.lexiconVerb is not "switch") {
31 fb_throw("fusebox.badGrammar.invalidNesting",
32 "Verb is invalid in this context",
33 "The verb 'case' does not appear directly nested within a 'switch' verb in fuseaction #fb_.verbInfo.circuit#.#fb_.verbInfo.fuseaction#.");
34 }
35 //
36 // value is required:
37 if (not structKeyExists(fb_.verbInfo.attributes,"value")) {
38 fb_throw("fusebox.badGrammar.requiredAttributeMissing",
39 "Required attribute is missing",
40 "The attribute 'value' is required, for a 'case' verb in fuseaction #fb_.verbInfo.circuit#.#fb_.verbInfo.fuseaction#.");
41 }
42 //
43 // delimiters is optional:
44 if (structKeyExists(fb_.verbInfo.attributes,"delimiters")) {
45 fb_.delimiters = ' delimiters="#fb_.verbInfo.attributes.delimiters#"';
46 } else {
47 fb_.delimiters = '';
48 }
49 //
50 // start mode:
51 fb_appendLine('<' & 'cfcase value="#fb_.verbInfo.attributes.value#"#fb_.delimiters#>');
52 } else {
53 //
54 // end mode:
55 fb_appendLine('<' & '/cfcase>');
