Release Options

When building a MongooseIM release from source code, the initial configuration files are generated with options taken from the vars-toml.config file found in the [MongooseIM root]/rel/ directory. You can change the values in this file to affect the resulting vm.args and mongooseim.toml files.

The file contains erlang tuples terminated with period ('.'). For users not familiar with Erlang syntax, here is a quick cheat sheet:

  • Each config option (key and value) is a tuple. Tuples are (Erlangers, forgive us the simplification) other Erlang terms separated with commas and enclosed in curly brackets ({}).
  • Tuples (at least the top-level ones) in vars.config are always 2-element.
  • The first element of each tuple is the name (Erlang atom).
  • The second element is a quoted string. Any quotes (") inside the string should be escaped with a backslash (\).

There are two types of options: parameters and blocks:

  • a parameter is inserted into the value of an already defined option. Parameters are mandatory - a valid value has to be provided.
  • a block can be an empty string, one line or multiple lines, defining zero, one or more options. Blocks are optional - the default is an empty string.

vm.args options

These options are inserted into the rel/files/vm.args template.
