Print All Structures in a Golang Package
The program is designed to traverse and analyze Go language source code within a specified package directory. It utilizes the go/parser and go/token packages to parse the abstract syntax tree (AST) of each Go file. The main functionality includes:
-
Parsing Package Files: The program reads and parses all Go files within a given directory, creating an AST for each file.
-
Identifying Struct Definitions: It searches through the AST to find all declarations of struct types.
-
Preserving Comments: The program retains comments that are associated with the struct definitions and their fields.
-
Formatting and Printing Structs: The struct types, along with their fields and associated comments, are formatted to resemble the original Go code. The program uses the
go/formatpackage to ensure that the output closely matches the syntax and style of handwritten Go code. -
Output: The program outputs the struct definitions to the standard output (console), allowing users to see the struct types and associated comments in a readable format.
The program is invoked by running the main.go file with the -path flag set to the path of the Go package directory to be analyzed. The output can be used for documentation purposes, code reviews, or as a reference when working with existing codebases.
