Mix v1.9.4 mix compile.erlang View Source

Compiles Erlang source files.

When this task runs, it will first check the modification times of all files to be compiled and if they haven't been changed since the last compilation, it will not compile them. If any of them have changed, it compiles everything.

For this reason, the task touches your :compile_path directory and sets the modification time to the current time and date at the end of each compilation. You can force compilation regardless of modification times by passing the --force option.

Command line options

• --force - forces compilation regardless of modification times

• --all-warnings - prints warnings even from files that do not need to be recompiled

Configuration

• ERL_COMPILER_OPTIONS - can be used to give default compile options. The value must be a valid Erlang term. If the value is a list, it will be used as is. If it is not a list, it will be put into a list.

• :erlc_paths - directories to find source files. Defaults to ["src"].

• :erlc_include_path - directory for adding include files. Defaults to "include".

• :erlc_options - compilation options that apply to Erlang's compiler. Defaults to [:debug_info].

  For a complete list of options, see :compile.file/2.

For example, to configure the erlc_options for your Erlang project you may run:

erlc_options: [:debug_info, {:i, 'path/to/include'}]
