fpm-deps

Generate dependency graphs of fpm packages

To start using fpm-deps run the commands:

git clone https://github.com/ivan-pi/fpm-deps && cd fpm-deps   # clone project
fpm install --prefix $HOME/.local    # install in a directory on the user PATH
fpm-deps   # run fpm-deps in the root directory of an fpm project

The commands above will install the fpm-deps executable into the $HOME/.local/bin folder, assuming it is included in your shell's PATH.

Graphviz

The result can be piped to the Graphviz dot command, e.g.:

fpm-deps | dot -Tsvg -ofpmdeps.svg

resulting in

Mermaid

To generate a Mermaid dependency graph you can include in your Markdown documents (either Github- or Gitlab-flavoured markdown) use

fpm-deps --mermaid -o depgraph.mmd

Alternatively, you can output a standalone HTML page:

fpm-deps --mermaid html -o depgraph.html

The rendered output can be seen here.

ToDo list

• browse option (see browse in ninja)
• use style/colors to distinguish dependencies (local, git, registry)
• customize nodes with other package information
• offline mode (use only cached data)
• library dependencies (link-time)
• subgraph selection based on category/authors/...
