The variable substitution syntax for Octopus Deploy

Octostache is the variable substitution syntax for Octopus Deploy.

Octopus allows you to define variables, which can then be referenced from deployment steps and in scripts using the following syntax:

#{MyVariable}

This library contains the code for parsing and evaluating these variable expressions.

Usage is simple: install Octostache from NuGet.org, then create a VariableDictionary:

var variables = new VariableDictionary();
variables.Set("Server", "Web01");
variables.Set("Port", "10933");
variables.Set("Url", "http://#{Server | ToLower}:#{Port}");

var url = variables.Get("Url");               // http://web01:10933
var raw = variables.GetRaw("Url");            // http://#{Server | ToLower}:#{Port}
var eval = variables.Evaluate("#{Url}/foo");  // http://web01:10933/foo
