Show Specific Symbol Documentation
Display documentation on a specific symbol within a Go package.
go doc -all -src <encoding/json.Number> go doc -all -src <encoding/json.Number> #!/bin/bash

# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"go",
"doc",
"-all",
"-src",
"<encoding/json.Number>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: go not found. Please install it first.")
if __name__ == "__main__":
run_command() When To Use
During code review sessions to clarify functionality linked to symbols.
Pro Tip
Utilize the `-src` flag to inspect implementation details of the symbol directly from source files.
Anatomy of Output
Understanding the result
Symbol: <SymbolName> Symbol Name Defines the specific function/type being documented.
Documentation: <DocContent> Symbol Documentation Detailed description of the symbol's behavior and usage.
Source: <SourceFile> Source Location File and line number where the symbol is defined.
Power User Variants
Optimized versions
go doc -src encoding/json.Number Display the symbol's source code.
go doc -all encoding/json.Number Show all related symbols including methods.
Troubleshooting
Common pitfalls
FAIL: Symbol not found
Solution: Check for typos in the symbol name.
FAIL: Unsupported package
Solution: Ensure the package is standard or properly initialized.
FAIL: No documentation available
Solution: Confirm the symbol is exported.
