    // Test error case.
    TemplateSubject.assertThatTemplateContent("{let $alpha /}{/let}").causesError("parse error at '/}': expected }, ':', or identifier").at(1, 13);
    // Test error case.

Example 2 with LetValueNode

use of com.google.template.soy.soytree.LetValueNode in project closure-templates by google.

the class ResolveNamesVisitorTest method testMultipleLocals.

@Test
public void testMultipleLocals() {
    SoyFileSetNode soyTree = SoyFileSetParserBuilder.forFileContents(constructTemplateSource("{let $la: 1 /}", "{let $lb: $la /}", "{let $lc: $lb /}")).parse().fileSet();
    new ResolveNamesVisitor(ErrorReporter.exploding()).exec(soyTree);
    TemplateNode n = soyTree.getChild(0).getChild(0);
    // 3 because each new $la binding is a 'new variable'
    assertThat(n.getMaxLocalVariableTableSize()).isEqualTo(3);
    LetValueNode firstLet = (LetValueNode) n.getChild(0);
    LetValueNode secondLet = (LetValueNode) n.getChild(1);

}

Example 3 with LetValueNode

use of com.google.template.soy.soytree.LetValueNode in project closure-templates by google.

the class ResolveNamesVisitorTest method testLetContentSlotLifetime.

@Test
public void testLetContentSlotLifetime() {
    SoyFileSetNode soyTree = SoyFileSetParserBuilder.forFileContents(constructTemplateSource("{let $a kind=\"text\"}", // introduce an extra scope
    "  {if true}", "    {let $b: 2 /}", "    {$b}", "  {/if}", "{/let}", "{$a}")).parse().fileSet();
    new ResolveNamesVisitor(ErrorReporter.exploding()).exec(soyTree);
    TemplateNode n = soyTree.getChild(0).getChild(0);
