hirokidaichi / goviz Goto Github PK

Hi,

The filename display is nice but it behaves badly when packages contain a large number of files (e.g. golang.org/x/sys/unix).

Please consider adding an option to hide filename display,

Thanks

fish: Unknown command 'goviz'

Running goviz generates no output at all, I don't even get the help message with -h. No commands provide any output at all. It was installed with go get github.com/hirokidaichi/goviz. Using go version 1.6.3 on Ubuntu 16.04.1.

This is what I get. I can come back with config files if you want, but in a nutshell I'm running a pretty vanilla Mavericks with the latest go, brew, zsh, etc

It's super nice being able to use --search to limit to the packages that are part of an application without showing dependencies of all the third-party libraries.

It's also nice to combine --search with --leaf to show those third-party libraries without all the details.

But then all the standard library packages like fmt end up in the graph too. Maybe they could be excluded somehow?

For an example of what I'm thinking, something like this where the go-flags package is shown as is, but the other leaf packages (std) are not.

goviz -i github.com/hirokidaichi/goviz -s github.com/hirokidaichi/goviz -l | dot -Tpng -o viz.png

I would probably suggest hiding std packages by default and having a --std option to include them.

go get github.com/hirokidaichi/goviz Worked fine
sudo apt install graphviz Worked fine
goviz -i github.com/mattn/anko | dot -Tpng -o anko.png Had no output, image was not create
goviz -h No output
goviz executable is present in bin folder but executing it does not output anything.
