If I want to set -s -i -p in one command, How should I do?
Many Thanks!

Hi Kamil, thank you for that tool!

I want to see the package dependency inside one module.

I want to ignore other dependencies (like stdlib or external packages).

Is there a way to get this?

Hi!
I encountered an error:

~/work/my_project$ godepgraph -novendor -s -p github.com,google.golang.org,gopkg.in {gitlab_repo/project/subproject/package_name}

2021/03/25 00:13:56 failed to import {gitlab_repo/project/subproject/package_name} (imported at level 1 by ):

Environment:
go version go1.15.7 linux/amd64
Linux 5.4.0-70-generic #78-Ubuntu SMP Fri Mar 19 13:29:52 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Package go.mod contains header
module gitlab_repo/project/subproject/package_name

I assume that this is due to gitlab has subprojects and thus incompatible path to module.
How to resolve such behavior?
Thanks

If one uses vendored packages [1] in a folder "vendor" and sets
GO15VENDOREXPERIMENT=1 godepgraph won't list the
vendored ones, but the ones directly from GOPATH.

It would be cool if godepgraph could honour the GO15VENDOREXPERIMENT
environment variable and resolve the packages like the go tool does.

[1] https://golang.org/s/go15vendor

By default godepgraph will display packages in the standard library in the graph, though it will not delve in to their dependencies.

How do I turn this off?

The example graph does include the dependencies. How do you do that?

Although the command will start parsing dependencies, it fails at finding the imports in the modules cache, instead relying only on GOPATH/GOROOT.

Could you add an option to have the dependencies to the right, rather than below? Most import paths are quite long, and the depth of the imports quite shallow, so think at least in my case it would fit the screen better and be more readable.

Expected Behaviour

No vendored packages in the graph.

If you have a package in a directory named somepackage and import it from your main package using

import (
    "./somepackage"
)

and then you have another package named otherpackage and import somepackage in it using

import(
    "../somepackage"
)

It will be picked up as two separate packages, one being ./somepackage and the other being ../somepackage.

Potential Fix

For local packages like this, would it work better to resolve the absolute paths of relative packages. If two are the same, ommit one.
Afterwards, you can update their names again by generating the relative path to the package from the main package. Does this make sense?

Can we have an option to group packages by their Go module?
Meaning all packages inside a Go module be combined into one rectangle/node.
Including sub-packages of current module (root of the tree).
So that the nodes are modules, not packages.

Because that's what we generally mean by "dependency".
Once your module depends on a package from another module, your module depends on that module.

I'd like to see the chain of things that's leading me to pull in a whole bunch of questionable testing libraries into my project :)

Could we add a flag to enable delving into the dependencies of packages in the standard library, so that godepgraph can be used on those packages, too?

reading through such huge graphs is not of great use
better if it can collapse

It would be very useful if it would be possible to run for executable sources.

Commonly I am trying to move all functionality in separate modules and I clue logic at executable sources. But godepgraph can't parse not imported source files.

As I have commonly 2 executable sources then I just rename main to somename and it works.

Latest HEAD is having issues when I use import "C". Here's what I get.

2013/10/21 11:02:32 failed to import C: cannot find package "C" in any of:
/opt/local/go/src/pkg/C (from $GOROOT)
/Users/quest/Go/src/C (from $GOPATH)

If I go back to commit 369296b everything works as expected. Not sure how this regressed but I figured I would post an issue. =)

Hello -

I just cloned your project into my GitHub, & then tried to run it using your README guidance, & it doesn't work.

What am I doing incorrectly?

Here's the pertinent information:

$ pwd
/Users/ajpowel/GitHub/godepgraph

I don't even see an executable, or anything to build.

What am I missing here?

Many thanks for any guidance you can offer!

Best,

AJP

first thanks for your project.

thanks.

when I use -s and -i , the standard library is included in the output
