Go+ v1.1.0 vs. Go+ v1.0.39

First, it introduces the github.com/goplus/mod module. This module provides support for Go/Go+ module related capabilities. It can be thought of as enhancements to golang.org/x/mod which include:

Second, it has improved gop mod (module management) related commands, especially the gop mod tidy command needs to be considered in many cases.

Third, it enhances the completeness of gop command functions such as gop build/install/run/test, which are mainly reflected in:

  • Support for remote packages. For example, in Go+ v1.0 you could only gop run local directories or files, now gop run is supported to run a remote package.
  • Consistency of gop build/install/run/test. Previously, the codes of gop run and gop build/install were written separately, lacking a unified support framework, and their behaviors would be different. Now they are unified into the same implementation framework.
  • The gop cache bug has been eliminated. In Go+ v1.0, due to the poor implementation performance of the import package, the gop cache module cache was introduced, which led to some bugs in module update detection, and an infinite loop of importing some complex packages.

Fourth, it adds some syntax features that v1.0 does not have. This mainly includes:

  • Overloading of ++, -- operators is supported.
  • Expression type() is supported to represent the zero value of type type. For example, string() is equivalent to "", int32() is equivalent to int32(0), and so on.
  • Supports uint128, int128 types.
  • Supports the any type, which is equivalent to the empty interface.

Fifth, it adds support for comment instructions in structure and function headers. E.g:

//go:notinheap
type S struct{ x int }

//go:noinline
//go:uintptrescapes
func test(s string, p, q uintptr, rest ...uintptr) int {
    ...
}

Of course, the comment instruction still needs to be further improved. For example, conditional compilation instructions, etc., are currently not implemented.

Sixth, fix many bugs. It includes Go+ bugs (issue #888, #1056, #1228, #1243, etc.) and new test cases have been added in go1.8 version, which may not all pass in Go+ v1.0 version (issues #1195, #1196, #1197, #1198, etc.).

Seventh, it supports Go/Go+ hybrid projects. For details, please refer to the gop/testdata/mixgo example. The following is an introduction to this in the project's README file:

Eighth, support for calling C from Go+. This includes:

  • The gop c command (equivalent to the stand-alone c2go command) can be used to convert a C project to a Go project.
  • import "C" and import "C/xxx" are used to import a C project converted by c2go. where import "C" is short for import "C/github.com/goplus/libc".
  • The C"xxx" syntax represents C-style string constants.

Here is an example to show how Go+ interacts with C.

import "C"

C.printf C"Hello, c2go!\n"
C.fprintf C.stderr, C"Hi, %7.1f\n", 3.14

In this example we call two C standard functions printf and fprintf, passing a C variable stderr and two C strings in the form of C"xxx" (a Go+ syntax to represent C-style strings).

Run gop run . to see the output of this example:

Hello, c2go!
Hi,     3.1

Of course, the current Go+ support for C is only a preview version, not to the extent that it is actually available in engineering. As far as libc is concerned, the current migration progress is only about 5%, and it is just the beginning.

In the upcoming Go+ v1.2 version planning, complete support for C is listed as a top priority. Of course, support for cgo and Go templates is also under planning, which is a crucial capability enhancement for Go/Go+ hybrid projects.
