For example there is a -c option in Ruby that checks syntax before running a code:
C:\>ruby --help
Usage: ruby [switches] [--] [programfile] [arguments]
-c check syntax only
C:\>ruby -c C:\foouby\my_source_code.rb
Syntax OK
Is there a similar functionality in Go?
P.S. An example from Ruby is only because I know it in Ruby. Not because of trolling or something.
分享 You can use gofmt to check for syntax errors without actually building the project.
gofmt -e my_file.go > /dev/null
You can later use $? bash variable, return code 0 implies success, 2 means syntax check. /dev/null will eat the code, but the errors go to stderr
The -e option is defined as:
report all errors (not just the first 10 on different lines)
gofmt --help usage: gofmt [flags] [path ...] -comments=true: print comments -cpuprofile="": write cpu profile to this file -d=false: display diffs instead of rewriting files -e=false: report all errors (not just the first 10 on different lines) -l=false: list files whose formatting differs from gofmt's -r="": rewrite rule (e.g., 'a[b:len(a)] -> a[b:]') -s=false: simplify code -tabs=true: indent with tabs -tabwidth=8: tab width -w=false: write result to (source) file instead of stdout
