Martin Atkins	c753df6a93	lang/funcs: templatefile function ... This function is similar to the template_file data source offered by the template provider, but having it built in to the language makes it more convenient to use, allowing templates to be rendered from files anywhere an inline template would normally be allowed: user_data = templatefile("${path.module}/userdata.tmpl", { hostname = format("petserver%02d", count.index) }) Unlike the template_file data source, this function allows values of any type in its variables map, passing them through verbatim to the template. Its tighter integration with Terraform also allows it to return better error messages with source location information from the template itself. The template_file data source was originally created to work around the fact that HIL didn't have any support for map values at the time, and even once map support was added it wasn't very usable. With HCL2 expressions, there's little reason left to use a data source to render a template; the only remaining reason left to use template_file is to render a template that is constructed dynamically during the Terraform run, which is a very rare need.	7 years ago
Martin Atkins	129f5fe74d	lang/funcs: port some of Terraform's built-in functions ... These implementations are adaptations of the existing implementations in config/interpolate_funcs.go, updated to work with the cty API. The set of functions chosen here was motivated mainly by what Terraform's existing context tests depend on, so we can get the contexts tests back into good shape before fleshing out the rest of these functions.	8 years ago
