Description |
| <attribute> |
Evaluates to the value of attribute.ToString() if it exists else empty string. |
| <i>, <i0> |
The iteration number indexed from one and from zero, respectively, when referenced within a template being applied to an attribute or attributes. |
| <attribute.property> |
Looks for property of attribute as a property (C#), then accessor methods like getProperty() or isProperty(). If that fails, StringTemplate looks for a raw field of the attribute called property. Evaluates to the empty string if no such property is found. |
| <attribute.(expr)> |
Indirect property lookup. Same as attribute.property except use the value of expr as the property_ name. Evaluates to the empty string if no such property is found. |
| <multi-valued-attribute> |
Concatenation of ToString() invoked on each element. If multi-valued-attribute is missing his evaluates to the empty string. |
| <multi-valued-attribute; separator=expr> |
Concatenation of ToString() invoked on each element separated by expr. |
| <template(argument-list)> |
Include template. The argument-list is a list of attribute assignments where each assignment is of the form arg-of-template=expr where expr is evaluated in the context of the surrounding template
not of the invoked template. |
| <(expr)(argument-list)> |
Include template whose name is computed via expr. The argument-list is a list of attribute assignments where each assignment is of the form attribute=expr. Example $(whichFormat)()$ looks up whichFormat's value and uses that as template name. Can also apply an indirect template to an attribute. |
| <attribute:template(argument-list)> |
Apply template to attribute. The optional argument-list is evaluated before application so that you can set attributes referenced within template. The default attribute it is set to the value of attribute. If attribute is multi-valued, then it is set to each element in turn and template is invoked n times where n is the number of values in attribute. Example: $name:bold() applies bold() to name's value. |
| <attribute:(expr)(argument-list)> |
Apply a template, whose name is computed from expr, to each value of attribute. Example $data:(name)()$ looks up name's value and uses that as template name to apply to data. |
| <attribute:t1(argument-list): ... :tN(argument-list)> |
Apply multiple templates in order from left to right. The result of a template application upon a multi-valued attribute is another multi-valued attribute. The overall expression evaluates to the concatenation of all elements of the final multi-valued attribute resulting from templateN's application. |
| <attribute:{anonymous-template}> |
Apply an anonymous template to each element of attribute. The iterated it atribute is set automatically. |
| <attribute:{argument-name_ | _anonymous-template}> |
Apply an anonymous template to each element of attribute. Set the argument-name to the iterated value and also set it. |
| <a1,a2,...,aN:{argument-list_ | _anonymous-template}> |
Parallel list iteration. March through the values of the attributes a1..aN, setting the values to the arguments in argument-list in the same order. Apply the anonymous template. There is no defined it value unless inherited from an enclosing scope. |
| <attribute:t1(),t2(),...,tN()> |
Apply an alternating list of templates to the elements of attribute. The template names may include argument lists. |
| <first(attr)> |
The first or only element of attr. You can combine operations to say things like first(rest(names)) to get second element. |
| <last(attr)> |
The last or only element of attr. |
| <rest(attr)> |
All but the first element of attr. Returns nothing if $attr$ a single valued. |
| <strip(attr)> |
Returns an iterator that skips any null values in $attr$. strip(x)
=x when x is a single-valued attribute. |
| <length(attr)> |
Return an integer indicating how many elements in length $attr$ is. Single valued attributes return 1. Strings are not special; i.e., length("foo") is 1 meaning "1 attribute". Nulls are counted in lists so a list of 300 nulls is length 300. If you don't want to count nulls, use length(strip(list)). |
| \$ or \< |
escaped delimiter prevents $ or < from starting an attribute expression and results in that single character. |
| <\ >, <\n>, <\t>, <\r> |
special character(s): space, newline, tab, carriage return. Can have multiple in single <...> expression. |
| <\uXXXX> |
Unicode character(s). Can have multiple in single <...> expression. |
| <! comment !>, $! comment !$ |
Comments, ignored by StringTemplate. |
