如何从Go编译的语言x包中获取类型信息？

Question

I want to write a simple editor with basic autocomplete functionality for the Go language as a pet project. How would one go about doing it? I took a look at the Go plugins for Eclipse and IntelliJ, but they were too big for me to comprehend (not to mention getting one to compile).

Answer 1

The Go standard library offers the building blocks for a Go parser which you can use to parse the source files and look for function definitions and the like.

There's also the godoc command which already does what you want: extracting method definitions and it's documentation. You may look in the source code to see how godoc is working or use godoc directly.

This editor written in Go projects has a manageable amount of code, you may look into it.
