Create graphs of Erlang systems and programs.
First, install graphviz. On Ubuntu:
$ sudo aptitude install graphviz
On OS X, download and install the OS X version of graphviz or use homebrew:
$ brew install graphviz
To compile grapherl, type:
$ make
or the equivalent ./rebar compile.
To start a grapherl shell after compilation, type:
$ erl -pa ebin
Alternatively, compile a grapherl stand-alone executable by doing:
$ ./rebar escriptize
This will produce a grapherl executable in the root directory. Use
the flags -h or --help to see wich arguments it needs.
Here's some examples of using grapherl.
The following two calls are equal. They will both generate
my_app.png in the current directory.
Eshell V5.7.5 (abort with ^G)
1> grapherl:modules("/path/to/my_app", "my_app").
ok
2> grapherl:modules("/path/to/my_app/ebin", "my_app", [no_ebin]).
ok
For example, if you have an Erlang release in the folder my_node,
you can create a application dependency graph in SVG format by doing
the following:
Eshell V5.7.5 (abort with ^G)
1> grapherl:applications("/path/to/my_node/lib", "my_node", [{type, svg}]).
ok
This will create my_node.svg in the current directory.
If you're using Gnome under Linux, use the option {open, "gnome-open"} to directly see the resulting image.
If you're using OS X, use the option {open, "open"}.
