Caveats if go package name doesn't start with github.com? - go

I've recently started using go and planned to use following directory structure for my code: src/mycompany.com/project (so package name would be mycompany.com/project/component), however during code review my coworker (who worked with go before) pointed out that it's a convention to place code in src/github.com/mycompany/project (so package name would be github.com/mycompany/project/component).
I can understand that this is convenient for personal projects, but it looks weird to me to have it for company projects. Why does it matter which source control website company is using? What if company will decide to move to bitbucket later on - should all projects be refactored to have package names starting with bitbucket.org?
It is definitely possible to not use github.com: kubernetes have package name starting with k8s.io/kubernetes, and go book has package names which start with gopl.io (and both use github).
Question is: are there any caveats if package name doesn't start with github.com? E.g. maybe dep won't work properly (go get seems to work fine) or something else?
Also: what is the right way to have package name mycompany.com/project and have source code hosted on github?

If you set up the web server at mycompany.com to host your Go packages, there's nothing at all wrong with that approach.
But if the only reason to do that is to have "vanity" package names, it's probably not worth it.
Put another way: Your package name must match its hosting location. If you're using GitHub to host your project at github.com/mycompany/foo then your package name is github.com/mycompany/foo--there's no choice in the matter.
If you want to host your software on GitHub but still use mycompany.com as the package name, then you could set up GitHub to host mycompany.com's web page using the GitHub pages feature. But if you're an established company, then you probably already have your site hosted elsewhere, and it's not an option to move hosting to GitHub. And even if you don't already have a company web site, there's practically no reason at all to do this for the sake of Go packages.

How to create an all-inclusive Go environment to meet the requirements set forth: "application must compile on shared server"

A little backstory:
I am creating my first Go web app for school. The professor said that I could use Go. I asked him if I could use the latest version, 1.13, rather than the version installed on the server, 1.10, to leverage the module management feature and the updated errors module. He did not say that I was restricted to 1.10 and even gave me the contact information of the server admin. I reached out to the server admin with my professor CC'd and he said he doesn't want to update the server's version of Go in the middle of the semester. He then included instructions on how to download, install, and use whatever version of Go that I need in my home directory.
Pick your version:
https://golang.org/dl/
Set it up for your own use:
https://golang.org/doc/install
I installed go 1.13 and updated my own envvars to reflect this version and everything works.
Well, the other requirement is that I have to hand my professor my project and that it has to compile on the server. I am thinking that if I hand him a bundle and give him directions on how to build it, then I've technically met the requirements of the project so far.
My question is, does Go have anything that takes my Go v1.13 environment and packages everything up so that the project can compile on the target server? I have only been able to find solutions along the lines of "just copy the project binary to your production server" but that doesn't help me. I need it to compile on the production server. Besides, I tried copying my binary to the production server and it couldn't find my html templates (stored in ./ui/html/ directory) but I guess that will be solved in this discussion or saved for another SO question later.
student#universityserver:~$ ./web
INFO 2019/09/22 10:21:52 Starting server on :5089
INFO 2019/09/22 10:23:03 <ipaddress>:63527 - HTTP/1.1 GET /
ERROR 2019/09/22 10:23:03 handlers.go:29: open ./ui/html/home.page.tmpl: no such file or directory
The only thing I can think of right now is to basically add everything they need (the go amd64 binary distribution and all modules) and write a script that handles it all (extract go in local folder, export envvars, build, etc.)
Dear, Professor.
Copy this tarball to your home directory, extract, run build_my_goapp.sh script.
Sincerely,
Your student
The answer in my case was that I can supply a Makefile that does anything I need it to do.
(It's actually good practice, if not an expectation, of a project that is turned in.)
The requirements were that my project needs to compile on the server and that I had to supply a Makefile. Therefore, any downloading, installing, and setting up of a Go environment for my project can be done, as long as everything happens in the user's environment and is not something that needs sudo to install correctly. The server does not have Docker.

Problems importing packages on Circle Ci Golang

I am using Circle CI to test my project. The project is a simple Go application consisting of a few packages and a main.go file. When referencing packages within my project I simply import them as "projectName/packageName" in the code. This works fine locally, however, when I push to git and it gets built on Circle CI I get the following errors.
package crypto-compare-go/handlers: unrecognized import path
"crypto-compare-go/handlers" (import path does not begin with
hostname)
I fixed this by prepending github.com/myGitUsername/projectName to my local package imports, this means that when I'm developing locally If I change one of the packages within my project, I have to push to git, then pull to be able to use them even though they are all under the same parent project folder. This seems like a slow, very inefficient process.
Has anyone had this problem with Circle CI before?

Nope. You get this wrong. Your go will use the local $GOPATH/src/github.com/myGitUsername/projectName dir to compile. You access github.com only if you run go get -u <package path>. It is documented in How to Write Go Code.
Note that you don't need to publish your code to a remote repository
before you can build it. It's just a good habit to organize your code
as if you will publish it someday. In practice you can choose any
arbitrary path name, as long as it is unique to the standard library
and greater Go ecosystem.

Correct structure of Golang repository

I am starting in Golang development. Right now my boss gave me the repository of a project that other developer made, now he's gone of the company and I am not able to ask him some things related to it. Right now I have a confussion about the project structure that he pushed to the repo, the structure is the next:
|-MyApp
|--bin
|--pkg
|--src
|----api (the code of the app)
|----github.com
|----golang.org
|----gopkg.in
To me, it's exaclty as the estructure of the Go, 1.- in the repo should not be only the api folder?
If I go to the api folder and make go run main.go I get a message that some packages are not found even when they are in the folder, 2.-how I specify the packages in the go run command?
3.- Is a good practice to set this kind of structure for the golang projects? I see in the code that he exported the packages only with "package1", if I copy and paste the code of the app inside the golang workspace then I have to specify the name of the folder to export the packages, example: "myApp/package1" so there I have that doubt. Thank you
That all depends. There is not a single right way for everything.
It seems as if this repo decided to vendor everything, the whole GOPATH. That is okay but with the "modern" vendor folder today one would do it probably differently.
Never do go run. That's for toy programs only. Build your software with go build and go install. These command work on package path.
For everything else: Please see the official documentation https://golang.org/doc/code.html and stick to it (which means you should move stuff around a bit).

Component Creation How-to

I want to create a component that will allow me to install other components, modules, and plugins that i personally use all the time. I will need to be able to change these modules, components, and plugins at anytime but updating the components and etc.. that i use and be able to add more plugins and etc as well. I would like this Component because it takes too much time to install them all individually and on multiple sites as a web designer. I also would need to have some instruction on how to add subtract plugins, modules, components, and etc. I am ok with not a total integration i would like to be able to just host the install file on my server with a link to my server where the file is located.
If anyone can help with this please do.
this is not a direct answer more of a personal workaround ( I do this on local host).
I create a site for example Joomlabase, when it asks for DB name call it Joomlabase then add my extensions
then when I need a copy
1) copy and paste the folder named Joomlabase in Windows Explorer to a new name.
2) go into Phpmydmin copy the joomlabase DB to the same name as the new site name.
3) DO a search and replace of Joomlabase to new site name in config.php file (there should be 5 changes) and your done.
For me it saves a lot of time because in admin alone I use at least 12 different extensions
There is a Joomla admin component called "Akeeba". It creates a snapshot of your files and database which you can easily deploy to another server. I use it often when pushing a new site to production from a QA server.
http://www.akeebabackup.com/download/akeeba-backup-core-for-joomla/index.html
Your question is way too broad, and the simple answer is that it would take much much much more work to maintain this 'super component' than you are currently spending simply installing the extensions separately when you need them.
The other answers here don't answer your question, but they provide some decent solutions to your actual problem.

TortoiseSVN: how to set up projects on a existing directory structure of source code

I have an old pet project I want to revive (haven't had enough time for it last year - small kid - you know) - so restored old copy of my dev folder from archive, but since I have rebuilt my machine since when - I can't remember what needs to be done now. I installed the latest version of TortoiseSVN, and the existing directory structure from my old dev machine looks like:
ProjectName
*SubProject1
**branches
***1.1
***1.2
**tags
**trunk
*SubProject2
**branches
**1.0.3
**1.0.4
**1.0.5
**tags
**trunk
I tried "import project" but it ask for a url - don't know what to specify there ...
can someone post a url to a good TortSVN tutorial - so I could set up my projects quickly (I guess I need to setup SubProject1 and SubProject2) - then I install AnkhSVN for VS2008
and will spend this Sunday coding like crazy while I still have some time ;-)
Rather than focusing on TortoiseSVN specifically, I would actually recommend that you review the SVN documentation first:
http://svnbook.red-bean.com/
A good understanding of what's going on behind the scenes is really helpful when using Tortoise, Ankh, or any other front end.
Getting to your question, the URL is the URL of your SVN repository, plus any subdirectories. An example could be
file:///C:/svn/trunk/ProjectName
if your repository were stored locally, or
http://my.repo.site/trunk/ProjectName
if it is hosted on the Web.
Just hit F1. TortoiseSVN has good built-in help docs.
The url it's asking for is the svn repo to import your project into.
The Url you refer to is likely the address of the project at the Subversion repository (wherever that is, since you didn't mention any). If you right click on your local directory and choose properties you should be able to see a subversion tab where you can find the address your project came from.
If you don't have the repository data, then I think the best thing to do is make sure to remove all the .svn folders from your project folders - good discussion here - and start anew with the files you have. This will mean you don't get all the history you had previously, but, lacking the repository, I don't think there's a way to recover anyway.
Then using whatever tools you'd like create a new repository somewhere, checkout the empty root, copy in all of your folders and then commit.
