Nov 02, 2024 pm 10:49 PMBuilding Multiple Go Package Binaries Simultaneously
The question revolves around building multiple package binaries simultaneously, as the default advice of using a top-level cmd folder doesn't seem to work. The provided code example shows a particular folder structure that enables building specific binaries correctly.
To build all binaries in one step using the go build command, a variation of the following is recommended:
cd $GOPATH/someProject for CMD in `ls src/cmd`; do go build ./src/cmd/"$CMD" done
This command iterates through the packages in the src/cmd directory and builds each package individually. The resulting binaries will be stored in their respective package directories.
Alternatively, if you don't wish to install the binaries into $GOPATH/bin, a script can be employed. This is a common practice in open source projects, where build scripts handle multiple binary production.
The following example script can be used:
cd $GOPATH/someProject for CMD in `ls cmd`; do go build ./cmd/$CMD done
This script iterates through the packages in the cmd directory and runs go build on each. The result is a set of binaries stored in their respective cmd package directories.
For further reference, the following popular projects provide examples of build scripts:
- Grafana: https://github.com/grafana/grafana/blob/master/build.go
- Torus: https://github.com/coreos/torus/blob/master/Makefile
- Caddy: https://github.com/mholt/caddy/blob/master/dist/automate.go

Golang is mainly used for back-end development, but it can also play an indirect role in the front-end field. Its design goals focus on high-performance, concurrent processing and system-level programming, and are suitable for building back-end applications such as API servers, microservices, distributed systems, database operations and CLI tools. Although Golang is not the mainstream language for web front-end, it can be compiled into JavaScript through GopherJS, run on WebAssembly through TinyGo, or generate HTML pages with a template engine to participate in front-end development. However, modern front-end development still needs to rely on JavaScript/TypeScript and its ecosystem. Therefore, Golang is more suitable for the technology stack selection with high-performance backend as the core.

In Go, if you want the structure field to use a custom field name when converting to JSON, you can implement it through the json tag of the structure field. 1. Use the json: "custom_name" tag to specify the key name of the field in JSON. For example, Namestringjson: "username"" will make the Name field output as "username"; 2. Add, omitempty can control that the output is omitted when the field is empty, such as Emailstringjson: "email,omitempty""

The key to installing Go is to select the correct version, configure environment variables, and verify the installation. 1. Go to the official website to download the installation package of the corresponding system. Windows uses .msi files, macOS uses .pkg files, Linux uses .tar.gz files and unzip them to /usr/local directory; 2. Configure environment variables, edit ~/.bashrc or ~/.zshrc in Linux/macOS to add PATH and GOPATH, and Windows set PATH to Go in the system properties; 3. Use the government command to verify the installation, and run the test program hello.go to confirm that the compilation and execution are normal. PATH settings and loops throughout the process

"Go:commandnotfound" is usually caused by incorrect configuration of environment variables; 1. Check whether Go has been installed correctly and use whichgo to confirm the path; 2. Manually add Go's bin directory (such as /usr/local/go/bin) to the PATH environment variable; 3. Modify the corresponding shell's configuration file (such as .bashrc or .zshrc) and execute source to make the configuration take effect; 4. Optionally set GOROOT and GOPATH to avoid subsequent module problems. After completing the above steps, run government and verify whether it is repaired.
