7.8 0.0 MANUL VS virtualgoVirtualgo: Easy and powerful workspace based development for go
Do you think we are missing an alternative of MANUL or a related project?
Manul is a vendoring utility for Go programs.
manul can be obtained using
go get github.com/kovetskiy/manul
What's the reason for yet another utility?
Because all other vendor utilities suffer from the following:
Some wrap the
gobinary and spoof the
GOPATHenv variable. You will have a non-go-gettable project which needs additional software in order to compile and run;
Some copy the source code of dependencies into the vendor directory:
- It will be nearly impossible to find anything using GitHub Search, because you will get many false-positive results;
- Updating dependencies will require manual intervention and committing a lot of modified lines straight into the main repo;
- You will not be able to tell what version of dependency your project is using will by looking at repository; you have to keep versions in the additional ambiguous file with vendors associated with commits.
Various architecture problems:
- Impossible to update all or specific vendored dependencies;
- Impossible to rollback vendored dependencies to specific version;
- Impossible to remove unused vendored dependencies;
- Impossible to lock version of vendored dependency.
We all love git, it's a very powerful instrument. Why don't we use its power for vendoring dependencies using an awesome feature, which is called git submodule?
With git submodule you will have a git repository for each dependency.
They can be managed in the same way as main project by
No need for additional software for building/running your Go project;
No need for additional JSON/TOML/YAML file for storing dependencies;
Update vendored dependencies directly from remote origins;
Rollback changes in dependencies;
git submodule might look like a Silver Bullet, but it's still clumsy to work with manually. We want to have a powerful yet simple interface for vendoring dependencies using this technology.
manul can do it for us.
Who needs a documentation when there are GIFs?
First of all, we should request dependencies which we have in our project.
To do this, just run manul with
-Q (query) flag. It will output all the
project imports (dependencies), like this:
For example, we have six dependencies, let's lock versions of critical
dependencies by adding submodules: in our case it's
For locking versions (installing dependencies) we should use
flag and specify dependencies, which we wish to install:
After installation we can have a look for vendored and non-vendored
dependencies by using flag
-Q. After previous step we should see git commits
along with two already vendored dependencies (
Let's install submodules for remaining dependencies, go the limit! Just run
manul with flag
-I without specifying any dependencies, manul will
install all detected dependencies with skipping already vendored:
Wow, that was crazy! Now, to update some vendored dependencies, for example,
docopt-go package, manul should be invoked with the flag
-U and import path
manul can be used to remove specified submodules of vendored dependencies
-R (remove) flag and specifying dependencies import path:
By the way, manul can detect and remove unused vendored dependencies using
manul can also get you a specific version of a dependency by using a commit-ish, for example:
manul -I golang.org/x/foo=34a235h1will install
fooat the specified commit
manul -U github.com/x/bar=this-tagwill update it to
-I [<dependency>...]- install git submodules for specified/all dependencies;
-U [<dependency>...]- update specified/all already vendored dependencies;
-R [<dependency>...]- remove git submodules for specified/all dependencies;
-Q [<dependency>...]- list all used dependencies;
-C- detect and remove all git submodules for unused vendored dependencies.
