What is the syntax of keybinds.settings?

问题

What is the syntax of the keybinds.settings? I am a vim user, and I would ultimately like to:

bind shift-j to go down 8 lines (nnoremap J 8j)
the same with k (nnoremak J 8k)
Use , as a "leader", i.e. I would like to bind ",b" to "build", and perhaps ",g" to run "ghci file-name" in a terminal.

回答1:

keybinding.settings file works only for cloud9 commands for now, for customizing vim commands you will have to use init script (see Open Your Init Script item in Cloud9 menu)

You can use following snippet

require(["plugins/c9.ide.ace.keymaps/vim/keymap"], function(vim) {
    var defaultKeymap = vim.aceKeyboardHandler.defaultKeymap;
    function ideCommand() { services.commands.exec(this.name); }
    function map(keys, action, context) {
        var mapping;
        if (!action) {
            return defaultKeymap.forEach(function(x) {
                if (x.keys == keys) {
                    x.defaultKeys = keys;
                    x.keys = "";
                }
            });
        } else if (/^c9:/.test(action)) {
            var commandName = action.substr(3);
            mapping = {
                keys: keys, type: "action", action: "aceCommand",
                actionArgs: { exec: ideCommand, name: commandName }
            };
        } else {
            mapping = { keys: keys, type: "keyToKey", toKeys: action };
        }

        if (context)
            mapping.context = context;
        mapping.user = true;
        defaultKeymap.unshift(mapping);
    }
    map("J", "8j", "normal");
    map("K", "8k", "normal");
    map(",", ""); // remove default mapping of ,
    map(",b", "c9:build", "normal");
    map(",g", "c9:run", "normal");
});

note that for ,g you need to create ghci runner, see https://docs.c9.io/custom_runners.html for details.
