1. gorename

The gorename command performs precise type-safe renaming of identifiers in Go source code.

Installation

go get golang.org/x/tools/cmd/gorename

Plugin

import sublime
import sublime_plugin
from subprocess import call
import threading

class Rename(threading.Thread):
    def __init__(self, offset, word):
        threading.Thread.__init__(self)
        self.offset = offset
        self.word = word

    def run(self):
        call(["/Users/anarchyrucks/go/bin/gorename", "-offset", self.offset, "-to", self.word])
        print(self.offset)
        self.view.run_command("gs_fmt")


class GoRenameCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        word = ""
        for region in self.view.sel():
            word = self.view.substr(self.view.word(region))
        self.view.window().show_input_panel("Go Rename:", word, self.do_rename, None, None)

    def do_rename(self, word):
        filepath = self.view.file_name()
        name = filepath.split('/')[-1]
        row, col = self.view.rowcol(self.view.sel()[0].begin())
        offset = self.view.text_point(row, col)
        offset_arg = filepath + ":#" + str(offset)
        ren = Rename(offset_arg, word)
        ren.start()

2. gokeyify

gokeyify turns unkeyed struct literals T{1, 2, 3} into keyed ones T{A: 1, B: 2, C: 3}.

Install

go get honnef.co/go/tools/cmd/keyify

Plugin

import sublime

        row, col = self.view.rowcol(self.view.sel()[0].begin())
        offset = self.view.text_point(row, col)
        offset_arg = filepath + ":#" + str(offset)

        process = Popen(["/Users/anarchyrucks/go/bin/keyify", "-json", offset_arg], stdout=PIPE)
        output_bytes, err = process.communicate()
        if err != None:
            print("Couldn't get the output")
            return
        else:
            output = output_bytes.decode('utf-8')
            try:
                json_output = json.loads(output)
                start = json_output['start']
                end = json_output['end']
                replacement = json_output['replacement']
                select_region = sublime.Region(start, end)
                self.view.replace(edit, select_region, replacement)
                self.view.run_command("gs_fmt")

    def run(self, edit):
        filepath = self.view.file_name()
        name = filepath.split('/')[-1]
        path = filepath.split(name)[0]
        if name.endswith("_test.go"):
            altpath = path + name.split("_test.go")[0] + ".go"
