We firstly setup a router(a pair of HTTP route with some logic) from the Package main import ( "net/http" "/gorilla/mux" ) func main ()
GOLAND GOPATH MOD
You can test a go package from a isolated environment from the GOPATH by creating using the mod command.Ĭommand is a official way to create modules in golang and it creates kind of a environment to work on a templated project and structure the project/module/package properly. Now, we have got the package so we can import it from anywhere in our go environment.
GOLAND GOPATH INSTALL
So, theĬommand is used to download and install a package along with its all dependencies. You should see a folder to be added in theĪnd inside of it we should have a mux folder with the latest version. , we won't be using it right away just to get a feel for installing and playing with packages at the moment. We have installed a package which is a powerful HTTP router and a URL dispatcher and it can also be used to make web applications. You can get the default location of your GOPATH environment variable from the simple shell command. GOPATH is the path or the location in your system's disk where all the packages and modules are stored. We use the CLI command to grab the packages into our You can get the documentation along with all references for a particular package on the official Golang We can now get into installing other packages which are not in the standard library. We will dive into some of them throughout this series. Which is used for reading and performing operations with text,įor working with files systems and operating system level stuff, and other packages which are specific to use cases like rendering templates, time, sorting, math operations, encoding, etc. Package from the math standard library package as a sub-package by using the statementīut that's unwanted and we import only the package which we really need. We can import these standard library packages just by parsing their name in the string quotes like we did with You can check out the entire list along with the documentation on the

The Golang Standard Library has some good number of packages which can be used for some general tasks like formatting input/output, file handling, web requests, system commands, etc.
GOLAND GOPATH CODE
Which is triggered when we run the package.īlank identifier but we didn't use it anywhere, still we don't get any error messages and it compiled the code successfully. We have already created many packages but none of them have been super useful so far, we just used the statementĪnd didn't use the package anywhere. most packages have functions that we can use in our own programs to solve a simple problem. Package in simplest of terms is a collection of go scripts that can serve a purpose. In this particular section, we will be covering the fundamentals of packages and exploring the standard library in golang. There are couple of types of packages like packages from the standard library, open sourced community packages and custom packages that you can build of your own. We can create a separate file which can include certain helper functions or variables from other files or scripts. Package is a cool way to organize code in large projects. Edit run/debug configurationįind "Add Configuration" at the top right of Goland and click.Ĭlick "+" in the pop-up window and select "Go Build" from the drop-down menu.įirst create a new Go source file, right-click on the project folder, then find "New" in the pop-up menu, and select "Go File" in the lower-level menu, and finally enter the file name in the pop-up box (in the red box ) And select "Empty file", press "Enter" key to confirm after correct.In this 11th part of the series, we will be covering packages in golang. It is recommended to fill in only the project GOPATH during development, and try to set only one GOPATH for each project, instead of using multiple GOPATH and global GOPATH. idea directory will not be set to the GOPATH of the environment variable, but it will be used during compilation. Represents global GOPATH, which is generally derived from GOPATH in system environment variables Project GOPATH represents GOPATH used by the project, and this setting will be saved in the working directory The. Gopath needs to be set in GOLAND IDE: Global GOPATH in Select a directory for the project (try to choose an empty directory), and click "Create" to complete the creation. find "New" in the "File" menu, and select "Project" in the lower menu to create a new project.
