Sometimes when using the hierarchical_collapse extension, I can't go into edit mode anymore by double clicking on a cell.

The slidemode is working great and I have customized the CSS to increase the font size, etc. However, there is one thing that I can't figure out how to fix - is there a way to make sure the content of a slide is vertically centered

Above you can see that for the title slide I have, the content is flushed to the top (like it is in the regular notebook). Is there an easy way to change that?

Has the location where the hotkeys are stored changed at all recently?

I'm getting errors from several of the extensions which attempt to assign keyboardcuts:

Uncaught TypeError: Cannot set property 'Alt-PGUP' of undefined navigation-hotkeys.js:11
Uncaught TypeError: Cannot set property 'Alt-C' of undefined comment-uncomment.js:11
Uncaught TypeError: Cannot set property 'Shift-Tab' of undefined

It looks like "IPython.hotkeys" doesn't exist when the extensions attempt to index into it.

Tested on IPython 1.1.0 and git (2013/11/26) on Arch Linux.

I have the codefolding files present:

$ls .ipython/profile_default/static/custom/codefolding/
codefolding.js  codefolding.py  firstline-fold.js  foldgutter.css  indent-fold.js

This is at the bottom of my custom.js:

$([IPython.events]).on('app_initialized.NotebookApp', function(){
    require(['/static/custom/codefolding/codefolding.js'])
    });

And yet starting a new notebook yields no new behavior. This is IPython 2.2. The python-markdown extension is also not working for me, so I suspect I'm doing something wrong. The executetime extension is working, but only if I load it in as an extension as a within the notebook.

Behavior doesn't change if I use the custom.example.js, uncommenting codefolding, executetime and python-markdown.

Profile directory: /home/jeffrey_alstott/.ipython/profile_default
Testing path /home/jeffrey_alstott/.ipython/profile_default/static/custom/custom.js
Found custom.js here: /home/jeffrey_alstott/.ipython/profile_default/static/custom/custom.js
And http://localhost:8888/static/custom/custom.js shows the correct custom.js file.

Update: Actually it looks like exectutetime is also giving incorrect results frequently.

Hi,

I installed the printview_button.js extension and changed my custom.js file per the instructions.

Upon opening an ipython notebook, I see the new button, but pressing it has no effect.

Using nbconvert from the command line works fine.

OS: Windows 7

Also, for my version of ipython, the attribute IPython.version in printview_button.js should probably be IPython.version_info.

I don't know if this is the right place to report this. I am using IPython 2.X and I downloaded the read only extension from the 2.x branch and installed it. But the promised tool bar is never shown.

I managed to successfully install other extensions, so I don't know what can be the cause for this.

Hey,

Just wanted to let you know that there a couple of syntax errors that initially prevented me from properly loading codefolding.js in the 2.x branch. They're in line 29 (missing 'var' in front of 'p') and another missing 'var' on lines 91 and 102. After I fixed these lines it seemed to work fine. Hope this helps.

J

in particular SWC and init_cell need to be passed "base/js/events" and the call to register_preset updated. assigning me.

sorry. Can I delete this?

When I run forward in a presentation using the "Next" button or the right arrow key, cells marked as "Notes" or "Skip" using the "Slide Type" cell toolbar are not shown.

But when I run backward using the left arrow key and cross a slide boundary, the whole previous slide is shown, including notes and skipped cells.

I can load an extension just fine in the notebook:

%%javascript
IPython.load_extensions('usability/autoscroll');

However, when I try to autoload (using the custom.example.js), It fails to load, and I get the following error in the JavaScript Console in my browser:

Uncaught TypeError: Cannot read property 'on' of undefined                custom.js:57

which points me to the lines in custom.js

require(["base/js/events"], function (events) {
    events.on("app_initialized.NotebookApp", function () {

Any thoughts? I'm currently using IPython 2.3.0-74.5, and using the notebooks in Chrome 36.0.1985.143

custom.example.js is not working with IPython 2.2. Each extension requires different IPython version?

My notebooks are easily growing too large. I want to split part of it to another notebook. Currently I can only cut/paste per cell using the chrome_clipboard extension. Is multiple cell or section operation supported?

The "x" cut-cell hotkey in IPython also triggers the collapse of a group of cells with the hierarchical_collapse extension running. Details:

On Windows machine, running Python 2.7.3, IPython 2.2, running notebooks extensions from the 2.x branch. Hierarchical_collapse is the only enabled extension.

I like to interact with the notebook while in slideshow mode. It's cumbersome to toggle between presentation mode and interactive mode using the mouse. It would be convenient if there were global shortcuts for navigating the slideshow in interactive mode.

I've used this Javascript cell as a work-around, but it would be nice to have this built in:

    %%javascript

    IPython.keyboard_manager.command_shortcuts.add_shortcut('left', {
        help : 'Slideshow back',
        help_index : 'slidemode',
        handler : function (event) {
            IPython.slideshow.prev();
            return false;
        }}
    );

    IPython.keyboard_manager.command_shortcuts.add_shortcut('right', {
        help : 'Slideshow forward',
        help_index : 'slidemode',
        handler : function (event) {
            IPython.slideshow.next();
            return false;
        }}
    );

    IPython.keyboard_manager.command_shortcuts.add_shortcut('space', {
        help : 'Slideshow forward',
        help_index : 'slidemode',
        handler : function (event) {
            IPython.slideshow.next();
            return false;
        }}
    );

codefolding.js has includes loaded in from:

'/nbextensions/usability/codefolding/indent-fold.js',
'/nbextensions/usability/codefolding/firstline-fold.js'

and

load_css("/nbextensions/usability/codefolding/foldgutter.css");

but the documentation suggests locating codefolding dir as /static/custom/codefolding/ ?

We might want to turn ipython/ipython#4356 into an extension and write docs at the same time. I know that @damianavila is working on smth similar.

From @fperez by mail

For certain notebooks, even if we mark cells as 'no type' after a 'slide' cell type, the 'no type' cells still get revealed only one at a time as if they were marked 'fragment'. Do you have any idea of what could be going on?

I was able to replicate it with an empty notebook and just adding a few cells, the first marked 'slide' and the others unmarked...

I'm new to IPython Notebook, but stumbled over this extension because of the image copy/paste support.
So my question is, would it be an idea to save the images to disk, to overcome the big fat blob issue? I saw "writefile" magic, wouldn't this be an available technique?
Or is this a security thing, because of running in a browser?

Thank you very much for sharing this work!

Ipython 2.0-git (2013/11/26).

for example: split-combine does not currently work.

The fix is easy, as it says in custom.js:

// do not use notebook loaded event as it is re-triggerd on
// revert to checkpoint but this allow extesnsion to be loaded
// late enough to work.

so just call init_keyevent() ie take it out of the event;

a couple of lines should change- this way it works with me

Say I want to have some code evaluated only during presentation- currently I see no option...

pymdpreprocessor.py fails with the following error when given a notebook where a markdown cell refers to a nonexistent variable:

I'm running:

I'm using IPython 2.x. An example failing notebook is here.

I can't get Ipython to find my custom.js

When I start the Ipython notebook, and visits http://127.0.0.1:8888/static/custom/custom.js in my browser, I get the default file (located in /Users/allan/Library/Python/2.7/lib/python/site-packages/IPython/html/static/custom/custom.js on my system).

To sum up what I did to install these plugins, I think the command line actions will be the most efficent way to describe it ($ is my prompt):

$ ipython locate profile
/Users/allan/.ipython/profile_default

$ cd /Users/allan/.ipython/profile_default

$ git clone https://github.com/ipython-contrib/IPython-notebook-extensions.git ./static/custom
Cloning into './static/custom'...
[... some output here – cloning was a success ...]

Then I put this custom.js in /Users/allan/.ipython/profile_default, /Users/allan/.ipython/profile_default/static and /Users/allan/.ipython/profile_default/static/custom, just to be sure it's picked up (which location is the right one?).

Please help – where did I go wrong?

I tried installing the python-markdown extnsions as the wiki suggested:

• Copied the python-markdown.js and pymdpreprocessor.py to C:\Users\jschulz\.ipython\nbextensions
• loaded a new notebook and put the following into the first cell

%%javascript
IPython.load_extensions('python-markdown');

• got the following error in the javascript console:
  Failed to load extension(s): TypeError: message: "Cannot read property 'security' of undefined"

Afterwards my notebook is not useable anymore: I can't get into edit mode anymore (at least and starting to write 'import' omits 'i' and if a write something with 'a' I get a new cell above). This issue was also present after reloading the notebook and only went away after deleting the %%javascript cell.

I use the notebook from anaconda (ipython-notebook 2.1.0) and chrome.

Hey,

I'm really enjoying the NB extensions ... keep up the great work. I had a potential issue/question with python-markdown (2.7 series, using most recent version in that branch). I figured I'd post here (not sure if this is the "appropriate" place.)

I'd like to have a Python string variable that contains a URL turn into a clickable link in Markdown. If the python cell contains:

  URL = "[Google](http://www.google.com)"

and the Markdown cell contains

  {{URL}}

The link is rendered in the Markdown cell as:

  'Google'

but when I click the link, it asks to close the current Notebook page rather than opening Google in a new tab (If I put the raw markdown in the cell with no "{{}}"" then clicking 'Google' DOES open in a new tab as expected). Also the single quotes around the string also seem wrong. I'd like to just have the word appear as a hyperlink, if possible.

I notice in the python-markdown.js code that it appears that a "_blank" value is attached to the HTML target key (Line 106), but this doesn't seem to work. I'm not a javascript expert so rather than monkey around I thought I'd ask. Hopefully it's something simply I'm doing wrong.

Thanks for any help, and, again, I appreciate the effort.

in hotkeys.js this does the job if you insert them at the beginning of the document_keydown function (so pgup/down are not consumed by goto top/bottom of page):

    if (event.which == key.PGUP && event.altKey) {
        IPython.notebook.select_prev();
        IPython.notebook.scroll_to_cell(IPython.notebook.get_selected_cell());
        return false;
    };

    if (event.which == key.PGDOWN && event.altKey) {
        IPython.notebook.select_next();
        IPython.notebook.scroll_to_cell(IPython.notebook.get_selected_cell());
        return false;
    };

I'm trying to create a live slideshow using the slidemode extension. However, for some reason only cells marked as Slide or Sub-Slide are shown, all other cells are skipped. This means I can only have a single cell on each slide.

What I did:

• Cloned this repo, as per instruction

• Un-commented the following lines in custom.js:

  require(['custom/slidemode/main'],function(slidemode){
  // do stuff
  })

• Created a notebook with the structure Slide, Fragment, Slide

• Started the slideshow

Result: Only the Slide cells are shown. I can also mark the Fragment as - with the same result.

I'm using IPython 1.1.0, tried the slideshow on Chrome, Chromium, and Firefox.

Any help with getting this to work is highly appreciated. I was hoping to use the slide mode for a talk I'm giving tomorrow.

I am almost sure this is not the correct place to ask for help. However, I cannot find other. I want to have the functionality of hierarchical_collapse. However after fighting for several days I only have vague idea of what should be done. Unfortunately I am also new in ipython. I have successfully loaded gist, acording to the console log in chrome, after following the instructions in
https://github.com/ipython-contrib/IPython-notebook-extensions/wiki

I cloned the [email protected]:ipython-contrib/IPython-notebook-extensions.git repository, and copied the
but, once I try to do something similar with hierarchical_collapse, it says there is nothing to download. Moreover, in the console, I get a very simple message:

Failed to load extension(s): ["nbextensions/testing/hierarchical_collapse/main.js"]
Error: Script error for: nbextensions/testing/hierarchical_collapse/main.js http://requirejs.org/docs/errors.html#scripterror {requireType: "scripterror", requireModules: Array[1], originalError: Event, stack: (...), message: "Script error for: nbextensions/testing/hierarchica…http://requirejs.org/docs/errors.html#scripterror"}

although its there.
A similar behaviour with a simpler extension, namely cellstate.js:

Failed to load extension(s): ["nbextensions/testing/cellstate.js"]
Error: Script error for: nbextensions/testing/cellstate.js http://requirejs.org/docs/errors.html#scripterror {requireType: "scripterror", requireModules: Array[1], originalError: Event, stack: (...), message: "Script error for: nbextensions/testing/cellstate.j…http://requirejs.org/docs/errors.html#scripterror"}

If you cannot help me here, could you point me to a better place to seek help? Thanks!

From 2.x to 3.x there were several changes, that mandate changes to notebook extensions:

• require.js
• Codemirror: mode-> mode.name , python->ipython
• Fontawesome: ìcon-->fa-`

It seems there will be still some time until 3.0 is released, so we need some way to handle this.
Should we introduce a .2x branch where extensions for 2.x are located and use the master branch for 3.x ?

after merging 2 cells, undoing just deletes the text from the merged cell and this text is then lost. Required behavior is splitting the cells back

Following up from ipython/ipython#6511 cc @fera0013 who opened original issue.

After publishing an ipython notebook, make them side-comment able similar to the comment functionality in Google Docs. This would enable non-technical people to comment on published notebooks.

Currently many of the extensions do not work with non-default base_urls (defaults to /). None of the installation instructions are accurate either. The require lines all need to be something like:

require([IPython.notebook.base_url + 'static/custom/blah.js']);

All paths in the extensions themselves need similar updating, replacing any leading / with IPython.notebook.base_url

Based on the names of these extensions, they seem very interesting, but there is no documentation at all in any of the extensions, nor in the README.md files. Could someone take a few minutes and explain how you actually use one of these extensions that are in this github repo? There's (https://github.com/ipython/ipython/wiki/Extensions-Index), but that doesn't help for the extensions in this repo.

Thanks. I know documentation is not fun, but its necessary if you want people to use your code!

Ive installed python-markdown as per this instruction. I've edited my custom.js file to load the extension automatically, and this seems to work fine: using the cells from here, the output of code block 8 (uncommenting the print statements) returns

Extensions: ['python-markdown']
Active: [True] 

However, if I write a test I just get the straight text back:

a = 2.2

(markdown cell)

My variable is equal to {{a}}

returns

My variable is equal to {{a}}

rather than the expected 2.2.

I've also tried loading the extension using the javascript magic, and this has the same behaviour.

I'm using an Anaconda installation:

3.3.5 |Anaconda 2.1.0 (x86_64)| (default, Sep 2 2014, 13:57:31)
[GCC 4.2.1 (Apple Inc. build 5577)]

Any ideas why the extension appears to load fine but fail to do anything?

Sorry I wanted to make a PR using github UI who apparently directly commited on 2.x :-(

The commit is small though: de9912e

Sincere apologies.

(closing immediately)

So help_panel basically work but should be improved.

• is visible only for some browser window sizes and disappears if the window is too narrow
• gets truncated if the window is not high enough. Should there be a scrollbar in this case ?
• the table looks very plain.
• invents new dict IPython.hotkeys
• needs to initialize IPython.hotkeys=[]; in custom.js

Suggestions are welcome :-)

Hi,

I'm trying to install the codefolding plugin. I've copied into ~/.ipython/nbextensions/usability/codefolding. Afterwards I've added following to /.ipython/profile_default/static/custom.js:

// activate extensions only after Notebook is initialized
require(["base/js/events"], function (events) {
    $([IPython.events]).on("app_initialized.NotebookApp", function () {
        /* load your extension here */
        IPython.load_extension("usability/codefolding/codefolding");
    });
});

But my ipython document doesn't load. In browsers JS console I see:

Failed to load extension(s): ["nbextensions/usability/codefolding/codefolding"]
TypeError: IPython is undefined

Am I missing sth?

Cheers, Victor

Are the extension installing instructions up to date?

The instructions for the Miscellaneous IPython extensions use a different syntax:

copy the extension to the $(ipython locate)/nbextensions/ directory and load it by adding IPython.load_extensions('extension_name'); in custom.js

Could this also be applied top the extensions here?

When hitting the right arrow or clicking on the "Next" button, I see the following message in the JavaScript console:

cannot call methods on button prior to initialization; attempted to call method 'disabled'

In the browser, everything works ok except that whenever there's a "Notes" or "Skip" cell, nothing happens. It seems that the cell "counter" moves to the hidden cell, and only a second click reveals the next (non-hidden) cell.

To fix this, I made the following change to main.js:115:

this.progression = $('<button/>').addClass('btn').text(that.eta());

changed to

this.progression = $('<button/>').addClass('btn').text(that.eta()).button();

Now, we have a lot of js extensions in a big bag... maybe we can split this repo in subgroups where the extensions are related in some way...

As an example, I have Nikola-related (or blog-related) extension to upload... maybe some Styling-related extensions, and so on... what do you think? @Carreau @juhasch

Hello, has anyone tried to use the:

https://github.com/ipython-contrib/IPython-notebook-extensions/tree/2.x/usability/init_cell ?

Because it seems really nice but for me it doesn't work, i mean i can see the check box but as i understood another button should be created in the toolbar in order to run upon initialization but its not... and when i rerun/refresh/reopen the notebook/kernel/etc nothing happens.

I cannot find any documentation besides this:
http://nbviewer.ipython.org/github/Carreau/posts/blob/master/04-initialisation-cell.ipynb
Which is actually not very helpful,

P.S.: my env: Anaconda: 2.1.0 (x64) - Python 2.7.8 – IPython 2.3.1

Thank you in advance.

The Styling extensions appear to not be working well for me. css_selector creates a new dropdown menu, I assume to select different css styles, but the only option is "default". Zenmode does nothing; not even a button. Is there another step required to make those work?

After checking out the master branches ipython-3.0 and ipython-notebook-extentions-3.x. I can't load codefolding. All other extensions works fine.

Hi guys,

I've merge My repo and @juhasch one, in here so that we can update each-other javascript extension.

I'll tried to use a subtree and the a git mv to keep the history and contributions. It seem to have worked.

I haven't fully merged the Readme, but things should still work the same as long as this is clone into the right place.

Despite the fact of some contributors here are IPython core devs... I think is not good to keep the official header in the files mentioning them as part of the IPython project. This is not a real fact. I think we need to remove it to avoid future conflicts.
@juhasch @Carreau thoughts?

I followed the instructions to install comment-uncomment.js, but nothing seems to happen. Using the same instructions (from https://github.com/ipython-contrib/IPython-notebook-extensions/wiki) I managed to get another extension working (codefolding). The output of firefox js console lists:

Initially installed this extension because CTRL-/ didn't work. This a spanish keyboard layout
