Variables in the template trueText nullText raise Template parsing error

[phyng]

If variables in the template start with true/false/null (<text>{{ trueText }}</text>), it will cause a syntax error.

Test:

https://npm.runkit.com/glass-easel-template-compiler

Code:

const glassEaselTemplateCompiler = require("glass-easel-template-compiler")
const g = new glassEaselTemplateCompiler.TmplGroup()
g.addTmpl('/path', '<text>{{ trueText }}</text>')
console.log(g.getTmplGenObjectGroups())

Return:

"Template parsing error (from line 1 column 14 to line 1 column 14) : Unexpected character"

It should be related to the syntax definition of this file:
