Switch

Summary

The switch tag is used to output one of n-sections when the switch variable matches one of the n-case statements. A default section can also be output if none of the n-case statements matches the switch variable.

Usage Examples

<switch @x@>
    <case value="Fred">
         Hello Fred.
    </case>
    <case value="Greta">
         Hello Greta.
    </case>
    <case value="Sam">
         Hello Sam
    </case>
    <default>
         I don't recognize your name.
    </default>
</switch>

Tcl-equivalent flags have the same meaning as in the tcl-switch statement. Supported flags include exact, glob, and regexp.

<switch flag=glob @x@>
    <case value="F*">
         Hello Fred.
    </case>
    <case value="G*">
         Hello Greta.
    </case>
    <case value="H*">
         Hello Sam
    </case>
    <default>
         You are in the section for people whose names start with F, G, or H.
    </default>
</switch>

Case tags also have an alternative form for matching a list of items.

<switch @x@>
    <case in "Fred" "Greta" "Sam">
         Your must be Fred Greta or Sam, but I'm not sure which one.
    </case>
    <default>
         I don't recognize your name.
    </default>
</switch>

Notes

• Any legal variables that may be referenced in the template may also be used in switch statements.

• Phrases with spaces in them must be enclosed in double quotes and curly braces to be matched correctly. Failure to quote words with spaces correctly results in an error.

    <case "{blue sky}">
      <td bgcolor=#0000ff>
    </case>
