I'm building Golang project on gitlab CI and I'd like to pass $CI_COMMIT_TAG value to compiler. With g++ it would be something like g++ -DCI_COMMIT_TAG=$CI_COMMIT_TAG .... Is there anything simillar for go build command?
main.go
package main
var YOUR_VARIABLE = ""
func main() {}
Shell command: go build -ldflags "-X main.YOUR_VARIABLE=$your_variable" main.go

Go: How does go run file.go work

I have an app. There are many .go files, but also there are files with tests.
Of course, the command go run *.go don't work correct.
And now I should write every time something like that: go run fileName.go fileName.go fileName.go and so forth.
Is it possible to run programs with a shorter command ?
Thank You

I would like to create command-line tool like git, go or aws in which we will pass some sub-commands to the main command and the last sub-command could also have some flags. Some examples are:
git add <file>
go build <file>
aws s3 cp --recursive <src> <dest>
Here are some examples of my hypothetical tool:
mytool cmd1
mytool cmd2 -f <path>
mytool cmd3 -f1 -f2 value --flag3 <path>
I know we can use the fmt package for defining and parsing flags, but I don't know if this package gives me the feature I described above or not. I was wondering if there is any built-in package for doing so?
just do a simple search on google and you can find anything

I run GDB on a program and get this after setting breakpoint main:
Missing separate debuginfos, use: debuginfo-install glibc-2.17-55.el7.x86_64
What exactly does it want?
It means that you should install a debuginfo package of the program you debugged. The package's name is always like this:
{package-name}-debuginfo.x86_64.
It is the package which includes the source code of the program you used, so when you debug the program it can locate many information like source file, line number and so on.

I have a scheme in Xcode 4. I edited the scheme so that Build has a Pre-Action, and that action is a script.
The script is simple - it dumps pre-processor defines: cpp -dM < /dev/null.
Where do I find the output of the script?
add this line to pre-action script
pwd > ~/current_directory.txt
then check file current_directory.txt in your home directory
