I upgraded Jupyter to the latest vesion, 5.0, and it looks like my front-end configuration stopped working.
I don't understand why Jupyter comes with auto closing quotes and brackets by default, which I find pretty annoying. So, at each version I have to change the settings to disable it.
It used to work by creating a file ~/.jupyter/custom/custom.js and adding the next JavaScript code:
require(['notebook/js/codecell'], function (codecell) {
codecell.CodeCell.options_default.cm_config.autoCloseBrackets = false;
})
I've read that since Jupyter 4 this code could be changed by:
IPython.CodeCell.options_default.cm_config.autoCloseBrackets = false;
But it looks like in Jupyter 5, the two previous options stopped working.
The documentation I found regarding the front-end configuration is not helpful (I'll be happy to improve it once I understand it):
http://jupyter-notebook.readthedocs.io/en/latest/frontend_config.html#frontend-config
Can anyone help me understand how to disable auto-brackets and auto-quotes in Jupyter 5 please?
This is the exact version I'm running:
It looks like it can be done by running in a notebook:
from notebook.services.config import ConfigManager
c = ConfigManager()
c.update('notebook', {"CodeCell": {"cm_config": {"autoCloseBrackets": False}}})
This creates a file ~/.jupyter/nbconfig/notebook.json with the content:
{
"CodeCell": {
"cm_config": {
"autoCloseBrackets": false
}
}
}
After executing the Python command, or manually creating the file, restart your Jupyter notebook, and it should stop auto-closing quotes and brackets.
For JupyterLab visitors there is a "User Preferences" panel of the "Notebook" settings editor into which you paste & save:
{
"codeCellConfig": {
"autoClosingBrackets": false
}
}
Open with Ctrl + , or via menu: Settings → Advanced Settings Editor & click "Notebook"
You can simply got to Settings tab and uncheck Auto Close Brackets option to disable auto-complete or check it to enable auto-complete
Here is my 2 jpgs:
[step 1] Go to "Advanced Settings" under "Settings" in menu:
[step 2]
Select the "Notebook" category, in the "User Preference" tab, add text as follows: (just follow the syntax shown in the "System Defaults" tab):
{
"codeCellConfig": {
"autoClosingBrackets": false,
},
}

I am trying Create simple notebook frontend extensions as described here
http://jupyter-notebook.readthedocs.io/en/latest/extending/frontend_extensions.html
This is what I have
~$ cat /home/usr/.local/lib/python2.7/site-packages/my_fancy_module/static/main.js // file my_extension/main.js
define([
'base/js/namespace' ], function(
Jupyter ) {
function load_ipython_extension() {
var handler = function () {
alert('this is an alert from my_extension!');
};
var action = {
icon: 'fa-comment-o', // a font-awesome class used on buttons, etc
help : 'Show an alert',
help_index : 'zz',
handler : handler
};
var prefix = 'my_extension';
var action_name = 'show-alert-usr';
var full_action_name = Jupyter.actions.register(action, action_name, prefix); // returns 'my_extension:show-alert'
Jupyter.toolbar.add_buttons_group([full_action_name]);
}
return {
load_ipython_extension: load_ipython_extension
}; });
When I try to install I get validation errors
$ jupyter nbextension enable /home/usr/.local/lib/python2.7/site-packages/my_fancy_module/static/main.js
--user Enabling notebook extension /home/usr/.local/lib/python2.7/site-packages/my_fancy_module/static/main.js...
- Validating: problems found:
- require? X /home/usr/.local/lib/python2.7/site-packages/my_fancy_module/static/main.js
I am very new to Python notebooks.
Additional information/questions:
When I pip installed my_fance_module it did not copy over the static directory and the .js files inside. I had to manually copy them to ~/usr/.local/ path afterwards.
This is my directory structure
.local/lib/python2.7/site-packages/my_fancy_module
-- __init__.py
|static
--- main.js
Also after installing this main.js and running server and notebook shows only main.js and does not show my notebooks anymore on the browser.
Have you tried?
jupyter nbextension install /home/usr/.local/lib/python2.7/site-packages/my_fancy_module/static/main.js --sys-prefix
before;
jupyter nbextension enable /home/usr/.local/lib/python2.7/site-packages/my_fancy_module/static/main.js
Also what version of Jupyter are you working with? Because the path that you indicated appears to be your systems default Python 2.7 that it ships with. If your developing for Jupyter notebook then I think it would be wise to first install Anaconda then install Jupyter notebook through it conda install notebook then migrate your files to you Anaconda dir. So let me know if that doesn't work out for you.
Before you flag this has duplicate, I want to point out that I did read the posts here and all of them tell me to change the code in
~/.jupter/custom/custom.js
However, there is no such directory as custom and no such file as custom.js
Also, if I add the above files and the code, then too it is autosaving.
Any help is greatly appreciated.
Update: jupyter version is : 4.3.0
Operating System: Ubuntu 16.04
Installed via pip
Put that in the custom.js:
define([
'base/js/namespace',
'base/js/events'
],
function(IPython, events) {
events.on("notebook_loaded.Notebook",
function () {
IPython.notebook.set_autosave_interval(0); //in milliseconds
}
);
//may include additional events.on() statements
}
);
I have the following:
ipyparallel (5.0.0)
ipython (4.0.3)
I have enabled ipcluster by typing in the command line:
ipcluster nbextension enable
I'm trying to create a new cluster on the IPython Clusters tab on the Jupyter notebook, but this is what I see:
I was able to do this before. Thanks!
From here:
Instead of editing jupyter_notebook_config.py, edit jupyter_notebook_config.json and look for:
"NotebookApp": {
"server_extensions": [
<some lines>
]
change this to:
"NotebookApp": {
"server_extensions": [
<some lines>,
"ipyparallel.nbextension"
]
I've just stumbled upon the same problem, and the fix mentioned in the accepted answer worked, but let me add some context for the future visitors of this question, just in case.
I have Anaconda 5.0 for Linux, under that I first did:
jupyter notebook --generate-config
pip install ipyparallel
jupyter nbextension install --py ipyparallel --user
jupyter nbextension enable --py ipyparallel --user
jupyter serverextension enable --py ipyparallel --user
Which lead to the situation on the screenshot.
Under ~/.jupyter I have both jupyter_notebook_config.json as well as jupyter_notebook_config.py.
The json file had this inside:
{
"NotebookApp": {
"nbserver_extensions": {
"ipyparallel.nbextension": true
}
}
}
I changed the file by adding a "server_extensions" block as follows:
{
"NotebookApp": {
"nbserver_extensions": {
"ipyparallel.nbextension": true
},
"server_extensions": [
"ipyparallel.nbextension"
]
}
}
After restart, Jupyter reported in the logs:
[W 19:44:14.107 NotebookApp] server_extensions is deprecated, use nbserver_extensions
However, the Clusters tab started working as necessary. Apparently, some recent changes in the configuration logic did not propagate to all of the codebase.
I am trying to launch R from sublimetext2 via sublimeREPL. Until I installed the new OS everything worked, now not anymore since the directory is not found apparently. I tried all variations but I cannot make it work. Here are my SublimeREPL User settings:
{
"default_extend_env": {"PATH": "{PATH}:/Applications/R"},
"default_extend_env":{"COLUMNS": "500"},
"wrap_width": 200,
"word_wrap": false,
"pep8_ignore":["E251","E501","W191","E303"]
}
Any idea what this might be about?
I solved it: After installing "el capitan", the permissions to access for sublime seemed to be deleted. I reeinstalled R and all worked.
$ wget --quiet http://download.qt-project.org/official_releases/qt/5.2/5.2.1/qt-opensource-windows-x86-msvc2012_64_opengl-5.2.1.exe
$
As seen above, I first downloaded the Qt package for Visual Studio in a Cygwin Bash shell.
A sidenote: The Qt library packaged within Cygwin is not useful for me because I need to use the Visual Studio C++ compiler.
First I set the correct permissions on the file
$ chmod 755 qt-opensource-windows-x86-msvc2012_64_opengl-5.2.1.exe
If I start it like this
$ ./qt-opensource-windows-x86-msvc2012_64_opengl-5.2.1.exe
a graphical window (GUI) is shown but that is not what I want as I would later like to have the installation procedure written into a Bash script that I could run in Cygwin.
If I add the option --help, like this
$ ./qt-opensource-windows-x86-msvc2012_64_opengl-5.2.1.exe --help
a new terminal window is opened with the following text

I don't know how to continue from here. Do you know how I could install the Qt 5.2.1 library (for Visual Studio) from the Bash shell in Cygwin?
Update: The advantage of writing the build script for a Cygwin environment is that commands like git, wget, and scp are available. This Stackoverflow answer describes how to invoke the MSVC compiler from a Cygwin bash script. Note, that the Qt application I'm building is not going to have any dependency on Cygwin.
I didn't test with Cygwin but I successfully installed Qt5.5 using a script. To do so, you must use the --script line of the normal installer.
.\qt-opensource-windows-x86-msvc2013_64-5.5.1.exe --script .\qt-installer-noninteractive.qs
Here's an example of qt-installer-noninteractive.qs file I used in the command above
function Controller() {
installer.autoRejectMessageBoxes();
installer.installationFinished.connect(function() {
gui.clickButton(buttons.NextButton);
})
}
Controller.prototype.WelcomePageCallback = function() {
gui.clickButton(buttons.NextButton);
}
Controller.prototype.CredentialsPageCallback = function() {
gui.clickButton(buttons.NextButton);
}
Controller.prototype.IntroductionPageCallback = function() {
gui.clickButton(buttons.NextButton);
}
Controller.prototype.TargetDirectoryPageCallback = function() {
gui.currentPageWidget().TargetDirectoryLineEdit.setText("C:/Qt/Qt5.5.1");
gui.clickButton(buttons.NextButton);
}
Controller.prototype.ComponentSelectionPageCallback = function() {
var widget = gui.currentPageWidget();
widget.deselectAll();
widget.selectComponent("qt.55.win64_msvc2013_64");
// widget.selectComponent("qt.55.qt3d");
// widget.selectComponent("qt.55.qtcanvas3d");
// widget.selectComponent("qt.55.qtquick1");
// widget.selectComponent("qt.55.qtscript");
// widget.selectComponent("qt.55.qtwebengine");
// widget.selectComponent("qt.55.qtquickcontrols");
// widget.selectComponent("qt.55.qtlocation");
gui.clickButton(buttons.NextButton);
}
Controller.prototype.LicenseAgreementPageCallback = function() {
gui.currentPageWidget().AcceptLicenseRadioButton.setChecked(true);
gui.clickButton(buttons.NextButton);
}
Controller.prototype.StartMenuDirectoryPageCallback = function() {
gui.clickButton(buttons.NextButton);
}
Controller.prototype.ReadyForInstallationPageCallback = function()
{
gui.clickButton(buttons.NextButton);
}
Controller.prototype.FinishedPageCallback = function() {
var checkBoxForm = gui.currentPageWidget().LaunchQtCreatorCheckBoxForm
if (checkBoxForm && checkBoxForm.launchQtCreatorCheckBox) {
checkBoxForm.launchQtCreatorCheckBox.checked = false;
}
gui.clickButton(buttons.FinishButton);
}
The tricky part was to found the id of the components! I was able to found the right id qt.55.win64_msvc2013_64 by adding the flag --verbose and installing it normally with the UI and stopping at the last page; all the ids that you selected for installation are there.
There is slightly more information in this answer if you need more details.
EDIT (29-11-2017): For installer 3.0.2-online, the "Next" button in the "Welcome" page is disabled for 1 second so you must add a delay
gui.clickButton(buttons.NextButton, 3000);
EDIT (10-11-2019): See Joshua Wade's answer for more traps and pitfalls, like the "User Data Collection" form and "Archive" and "Latest releases" checkboxes.
