Summary
Request for some additional explanation regarding customization
Environment
- Operating system : (e.g. Ubuntu 14.04 64bit)
- Web browser : (e.g. Firefox 45)
- Version or revision of Jupyter Notebook : (e.g. 4.2.2)
- Revision of jupyter-vim-binding : (e.g. 3e4030d)
Difficulties
I am not familiar with JavaScript, its libraries and the technology surrounding it. Advice on how to organize customization code would be very helpful. Thanks in advance.
Order of loading
If I understand correctly, customization Code should be run after the vim-bindig extension has been loaded. But it's not clear to me how to achieve a certain order. From what I can see, custom.js is executed first, then extensions are loaded.
I tried following this guide http://akuederle.com/customize-ipython-keymap to create an extension for additional key bindings and force it to load after vim-binding. The following code in my custom.js produces the desired order most of the time.
require(['base/js/utils'],
function(utils) {
utils.load_extensions('vim_binding/vim_binding');
setTimeout(function() {
console.log("additional");
utils.load_extensions('additional_shortcuts');
}, 3000);
});
What's the correct way to do it?
Customizing the design by putting code into ~/.jupyter/custom/custom.css has no effect. I assume it's because those settings are overridden once the vim-binding is loaded.
CodeMirror Vim Mode
I would also like to ask for help with customizing the CodeMirror's Vim Mode. My additional_shortcuts.js contains
require(['nbextensions/vim_binding/vim_binding'], function() {
CodeMirror.Vim.defineOperator("comment_op",
function(cm) { cm.toggleComment(); });
CodeMirror.Vim.mapCommand("gc", "operator", "comment_op", {});
});
which works fine to toggle comments on a selection or a text object. Is there a way to add a mapping gcc that would toggle comments on current line, or is the common prefix gc a problem? I tried with map and defineAction but they we not called.
How to provide a Ctrl-c insert mode mapping to return to normal mode? This does not work.
CodeMirror.Vim.map("<C-c>", "<Esc>", "insert");
