Plugin attempts to resolve JS variables with the '$' character in name

[imjayson]

tried to render an angular JS file and hit error when plugin attempts to resolve non-grails variables like '$routeProvider'.

$ signs are quite common in frameworks like angular and jquery. need a way to escape these dollar signs or only render items surrounded by ${}.

Yeah, this is an unfortunate side-effect of using the groovy.text.SimpleTemplateEngine for parsing files. It assumes that anything starting with a $ must be a groovy expression. I've looked a bit at extending it, but it's pretty nasty code from an extensibility standpoint (private inner classes that also have private methods, ugh).

How I've used the plugin is that I tend to have a few relatively small js-gtpl plain JS files that have all of my groovy template stuff in it (to import enums and get config values). Then concatenate that with the other files with the asset-pipeline plugin. Those are the files that use things like $http, $routeProvider, $, etc, but those just have .js extensions and don't use this plugin.

yup that's a good way to use the plugin, will do that.

thanks!

I've just take a look in to groovy 2.3.0 SimpleTemplateEngine class... The most part of code is located in "private static class SimpleTemplate" so I see only one way to fix it - just copy/paste it(SimpleTemplateEngine) and use it insetead default one ))))

Could you please tell how to concatenate the small js-gtpl groovy expression files in the .js file?
