Vintage Insert Bindings

Vintage Insert Bindings

Postby jopdeklein on Fri Oct 21, 2011 9:58 am

Jon, first of all thanks for the great product, and for providing the Vintage mode and python API.

I was personally missing a couple of VI bindings in insert mode so I implemented the ones I need most (and were easy to implement):
  • CTRL+W for left word delete
  • CTRL+H for left character delete
  • CTRL+U for undo of current line
  • CTRL+R for pasting
  • CTRL+O for one-command-mode

If any one is interested here are the keybindings:
Code: Select all
{ "keys": ["ctrl+w"], "command": "set_action_motion", "args": {
    "action": "vi_delete",
    "motion": "move",
    "motion_args": {"by": "stops", "word_begin": true, "punct_begin": true, "empty_line": true, "forward": false, "extend": true }},
    "motion_inclusive": true,
    "context":
    [
        { "key": "setting.command_mode", "operand": false },
        { "key": "setting.is_widget", "operand": false },
        { "key": "setting.vintage_ctrl_keys" }
    ]
},
{ "keys": ["ctrl+h"], "command": "left_delete",
    "context":
    [
        { "key": "setting.command_mode", "operand": false },
        { "key": "setting.is_widget", "operand": false },
        { "key": "setting.vintage_ctrl_keys" }
    ]
},
{ "keys": ["ctrl+u"], "command": "run_macro_file", "args": {
    "file": "Packages/User/Insert Undo.sublime-macro"},
    "context":
    [
        { "key": "setting.command_mode", "operand": false },
        { "key": "setting.is_widget", "operand": false },
        { "key": "setting.vintage_ctrl_keys" }
    ]
},
{ "keys": ["ctrl+r"], "command": "vi_paste_left",
    "context":
    [
        { "key": "setting.command_mode", "operand": false },
        { "key": "setting.is_widget", "operand": false },
        { "key": "setting.vintage_ctrl_keys" }
    ]
},
{ "keys": ["ctrl+o"], "command": "temp_command_mode",
    "context":
    [
        { "key": "setting.command_mode", "operand": false },
        { "key": "setting.is_widget", "operand": false },
        { "key": "setting.vintage_ctrl_keys" }
    ]
}


Insert Undo.sublime-macro:
Code: Select all
[
    {"command": "exit_insert_mode"},
    {"command": "undo"}
]


temp_command_mode.py:
Code: Select all

from threading import Timer
import sublime, sublime_plugin

times = 0


class TempCommandModeCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        self.view.run_command('exit_insert_mode')
        global times  # FIXME: is global a good idea?
        times = 0

        def check_history():
            global times
            last_command = self.view.command_history(0)

            if times < 500 and last_command[0] == 'temp_command_mode':
                sublime.set_timeout(check_history, 100)
            elif last_command[0] == 'vi_eval':
                # print 'entered command %s' % (last_command)
                try:
                    if last_command[1]['motion_args']['forward'] == False:
                        self.view.run_command('enter_insert_mode')
                    else:
                        self.view.run_command('enter_insert_mode', {"insert_command": "move", "insert_args": {"by": "characters", "forward": True}})
                except:
                    self.view.run_command('enter_insert_mode', {"insert_command": "move", "insert_args": {"by": "characters", "forward": True}})

            times += 1

        sublime.set_timeout(check_history, 100)


This is my first attempt at scripting ST2 so there's undoubtedly room for improvement, any suggestions are welcome.
The temp command is particularly nasty since I use a timeout to avoid having to register an expensive 'on_selection_changed' listener, if there's a better way please let me know.

Finally, I've been working on a couple of other commands such as CTRL+O from command mode to go to the previous location, and a way to visualize the characters you're 'Finding' (with f or F) in a line. If any other Vintage lovers are interested I can clean these up and publish them here.
