goviz
a visualization tool for golang project dependency
This tool is for helping source code reading.
The dependency of the whole code can be visualized quickly.
Installation
go get github.com/hirokidaichi/goviz
and if not being installed graphviz, install it :
brew install graphviz
Usage
goviz -i github.com/hashicorp/serf, dot -Tpng -o hoge.png
Option
Usage:
goviz [OPTIONS]
Application Options:
-i, --input= intput ploject name
-o, --output= output file (STDOUT)
-d, --depth= max plot depth of the dependency tree (128)
-f, --focus= focus on the specific module
-s, --search= top directory of searching
-l, --leaf whether leaf nodes are plotted (false)
-m, --metrics display module metrics (false)
Help Options:
-h, --help Show this help message
exit status 1

docker's metrics
goviz has a function which outputs the metrics (instability) of go project.
goviz -i github.com/dotcloud/docker/docker -m
Instability is a value of 0 to 1.
It suggests that it is such an unstable module that this value is high.
It becomes easy to distinguish whether it is a module nearer to application layer, and whether it is a module near a common library.
