GoDMT, the one and only Go Data Model Translator. The goal of this project is to provide a tool that can parse Go files that include var, const, map, struct and type into an abstract syntax tree, aka AST.

That AST will then be transformed into data models for several programming languages.

Some small adjustments may need to be made to integrate the output into a project, but this should already save you a lot of time and hassle, and will help you stay in sync with the Go version of your data models, in other languages. Comments will be carried over 😉.

Currently, the supported operating systems are all of UNIX family:

• Linux
• BSD
• macOS

Feel free to browse some examples that I am happy to provide here:

• Complex Structures
• Constants
• Maps
• Slices
• Structs

go run main.go -dir={scanDirectory} -translation={language} -preserve -tree

• scanDirectory represents a string that is the relative path of the directory whose Go files you want to scan. The scan occurs in a recursive manner, so all files from all contained folders will be scanned.
• language represents the output mode. If the -translation flag is not specified it will default to JSON. Currently supported options are:
  • ts or typescript for TypeScript conversion
  • swift for Swift conversion
  • json for JSON conversion
  • php for PHP conversion
• preserve is an optional boolean flag which will make the output structs preserve the original names, instead of using the (json:"tag").
• tree is an optional boolean that when present will prevent any file operations being performed, and instead will show you the full abstract syntax tree of your files in the standard output.

Example usage:

go run main.go -dir=../../tests/data/ -translation=ts

After a successful run, the program will output a result folder in the current working directory with subfolders for respective scanned packages. Filenames will be respected and maintained, with only changes to the extension.

To build this application as a binary simply navigate to cmd/godmt and run go build.
