I have gone through the issues and the solutions are not working for me.
I know they should, as I'm encountering the same problem with them but in my case the notebook in not in level3 or above folders:

Pasting the error below:

Hi,

I have upgraded to hide_code 0.5.
My problem still persists in that I am able to export my notebook to pdf via the terminal.
But, the buttons on the jupyter notebook doesn't seem to work.
I get 404 error now, where previously I used to get 500 Error.

The following is my output:
[W 00:28:37.636 NotebookApp] 404 GET /nbextensions/widgets/notebook/js/extension.js?v=20171010002821 (::1) 16.01ms referer=http://localhost:8888/notebooks/Desktop/pythonx/notebooks/Python3_OOP.ipynb

Kindly advise.

When I run the 3rd install command (after successfully running the first two commands) jupyter nbextension install --py hide_code I get the following error:

ValueError: No JSON object could be decoded

with the following traceback:

It would be great if you could fix this.

It would be great to have a Hotkey for code show/hide.

For now, I'm trying to use 'Keyboard shortcut editor' extension to assign a hotkey, yet I can't seem to find the command on the list.

Thanks again for great plugin!

I successfully installed and run hide_code, however when exporting to pdf via Latex, the output pdf still show all code in cells.

My system is Windows 7 64-bit, and running Jupyter Notebook from Anaconda environment. hide_code was installed with pip.

Here is the output prompt:

It seems like there is an issue, but I don't know how to fix it.

Thank you!

I use %run to run a python code and define some universal parameters in notebooks.
Also using following in Markdown cells to grab defined parameters from code cells and show as markdown.

Project:
{{parameter.replace("_"," ").title()}}

This works nicely in both html and pdf format through nbconvert, but using this extension it comes out as:
Project: {{parameter.replace(“_“,” “).title()}}

However, I expected:
Project: parameter value

Hi,

I have installed hide_code 0.5. While exporting to html, I met an error as the following:
"500 : illegal multibyte sequence".
In the notebook, there are Chinese characters.

I'd really appreciate some help.

This is not an issue but I want to know if we can include the table of content into the pdf conversion.
We have notebooks with TOC which is included in html format and interested to have that in the pdf format as well.

When I use the following to convert the notebook to PDF, all the pandas tables are not shown - no matter it's in pandas output directly or to_html or use Latex(df.to_latex()).

jupyter nbconvert --to hide_code_pdf notebook_to_convert.ipynb

Any idea how to fix this?

Hi, thanks for this awesome extension, it is just what I needed.

It works pretty well with another amazing extension, RISE, however when I want to export it to slides, it doesn't properly hide the input cells.

I use the following command to perform the conversion

jupyter-nbconvert my_file.ipynb --to slides --post serve

Do you have any ideia or any suggestion regarding this issue?

Thanks!

Thank you for this great extension! Is there any convinent way to export the latex file used to generate pdf? The raw tex file is useful when writing a report.

Hi,
This plugin is really perfect for focusing on the important part of the code.
It could be a good feature to keep the cells hidden or not when sending it to someone else (who has the plugin) or opening the same notebook again.

Thanks for the great job.

Hi,
When I try to install as root (on Ubuntu):

Running post install task
Starting hide_code.js install
Unable to install into /usr/lib/python2.7/site-packages/notebook/static/custom
Directory doesn't exist.
Make sure Jupyter is installed.

Install as a user doesn't work either.

My custom directory resides under ~/.jupyter/custom

Is there a way to fix the code to configure custom.js to auto-load hide_code.js in the .jupyter directory?

I have also modified my custom.js so will your install break the original custom.js?

When using Python-Markdown to call variables in markdown cells and then using jupyter nbconvert --to hide_code_pdf experian_report.ipynb to compile pdf, variables are outputted as {{ var }} instead of the actual number.

In a code cell:
a = 1.23

In a markdown cell:
The result is {{ a }}

Result in the markdown cell in notebook:
The result is 1.23

Result in compiled pdf:
The result is {{ a }}

This does not fail when compiling using jupyter nbconvert --to pdf notebook.ipynb

I can't seem to produce a HTML file with the output of a bash magic command.

My notebook only contains the following code cell.

%%bash
echo 'test'

Its output appears fine in the notebook, but disappears when I convert it to HTML. All hide_code tick-boxes are unchecked. Disabling the hide_code extension does show the output in the exported HTML file.

Much appreciated!

Clicking on the html export button gives a 404 not found. On the console:

[W 18:58:31.068 NotebookApp] 404 GET /notebooks/nalyze/testing-123.ipynb/export/html (127.0.0.1): No such file or directory: nalyze/testing-123.ipynb/export/html

As an utter jupyter newbie, I have no clue where to look for additional debug messages.

OS is Debian testing.

Hi, thanks for the plugin it seems nice but I can't get it working

Doesn't work on mac for me, I don't see any new icon, view menu:
pip install hide_code run without an issue, is there any other step I need?

The version of the notebook server is 4.1.0-0949a69 and is running on:
Python 2.7.10 (default, Jul 13 2015, 12:18:59) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)]

Thanks for your useful work! When exporting to HTML Jupyter 5.4.1 puts the correct title, however when exporting via the plugin button (I installed via pip) gives

<title>Notebook</title>

Also when using "Download as.." for a notebook named with spaces, e.g. "x y z.ipynb", it suggests a correct name "x y z.html", while the plugin suggests "x.html".

Thanks for writing the very useful code.
I am using 4.1.36-44 kernel on Leap 42.1. I can get the code to hide within Jupyter, but cannot get the code to hide in the output to html or pdf, either through command prompt or using the buttons. I get the error:

404 : Not Found

You are requesting a page that does not exist!

I tried putting the notebook file in the root directory of Jupyter and that did not help either. I have conda updated, I am using python 2.7 and nbconvert is ver. 4.2.0.
Any help will be appreciated.

Hi,

Thanks for the great plug-in. After I hide the code, the export to pdf still renders code cells. I am using "File" "Download As" "PDF" from the jupyter notebook browser.

Let me know if you have any suggestions. My goal is to render the notebook as a pdf without the code cells. Thanks!

I've installed hide_code as instructed but ever since I am getting

nbconvert failed: '/home/sfalk/workspace/playground/notebook/Untitled.ipynb' exists but is not a directory

I am using Jupyter 4.4.0 and 0.5.0 of hide_code.

On Windows, I get a 404 error similar to what we saw here when I click html export on a notebook that is 4 layers deep: tree/folder1/folder2/folder3. When the notebook is in folder1 or 2, things work. Thanks.

Does this feature work? #36 is closed suggesting that it should be possible to export slides, but I get an error ModuleNotFoundError: No module named 'hide_code.HideCodeSlidesExporter' when I try to run jupyter nbconvert --to hide_code_slides

Nice work creating this module. However I get an internal server error when I try to use the export to html button. I have all required modules installed and on the right version I think. Any ideas on why this fails?

I get these warnings and the resulting file still shows the code.

Any suggestions?

Hi, after I Install hide_code as following step:

pip install hide_code
jupyter nbextension install --py hide_code
jupyter nbextension enable --py hide_code
jupyter serverextension enable --py hide_code

I try to export PDF, but it still has "Code" in output.

then I go to
http://localhost:8888/nbextensions?nbextension=hide_code/hide_code.

I found there was a warning below:

-------------- warning start ------------
hide_code/hide_code

This nbextension is enabled in the notebook json config, but doesn't provide a yaml file to tell us how to configure it. You can still enable or disable it from here, though.

-------------- warning end ------------

How can I solve this problem?
Thanks very much for your help.

Hi,

First off, thanks for sharing the great tool. I hope to be able to enjoy it to produce nice & clean pdf notes. However, I ran into problems. I've installed the extension with no issues, restarted both the jupyter session and the browser but the hide_code toolbar still doesn't appear in the menu. I'm on OS X, Safari, anaconda, Python 2.7, nbconvert 4.2. What can be the problem?

Thanks in advance. Cheers

Luke

Hi,
You have done an amazing job with hide_code. Thanks for that.

I am having 500 error whenever I try to export a notebook via the buttons on the notebook.
I am using nbconvert 4.3.0, python 3.6 and notebook 5.0.

I am able to export using the command below:
jupyter nbconvert --to hide_code_pdf notebook_to_convert.ipynb

It's just that I am unable to use the buttons on the notebook to export as a pdf or html.

I tried restarting and installed hide_code multiple times but I am unable to find a solution.
I tried the command "jupyter nbextension list"
My output is below:

Kindly guide where I am going wrong.
Thanks alot for your precious time and effort.

See #23. Need to update to support installation via nbextensions.

• First of all, thanks for the tool! Was working great, but then for some reason it stopped code toggling.
• I click to show the code, but it does not reappear.
  - So the situation is that I can run the code, but can't see it, hence can't edit the code.
  Rebooted and so forth to no avail.

OSx 10.10
python35
notebook 4.2.3
ipython 5.1
jupyter 1

I'm having trouble getting hide_code to work correctly. The controls seem to work correctly in the UI, and the code cells toggle visibility as expected. However when clicking the "Export to HTML" button, the resulting HTML file always includes the code cells and makes them visible.

I've confirmed I'm using nbconvert 4.3.0, in case that matters.

The log shows

Warning: Failed to load file:///var/folders/kj/lwmmwfsd06vgf4vhxq0dc76jr802s3/T/custom.css (ignore)

Is it possible this is related to #18 ?

When I export the notebook using --to hide_code_html outputs for cells with print(variable) are not exported in the HTML, instead, there is black space in the HTML.

The problem persists even if I am not hiding the code for the cell.

Hello, I cannot understand why it happen, but if I end a cell with a print('hello') for example and then export to html, I get error 500. Log shows:

it took me a while but at the end I figured it out: try yourself to print in a new notebook. As workaround I'm using display() or HTML() at the moment.

Hi,

I'm trying to export to a notebook to a html file with codes hidden.
But, it returned an error message, "500: illegal multibyte sequence".
Can anyone help with this matter?

Many thanks in advance.

Hello,

It gives me "You are requesting a page that does not exist!" after clicking the exporting icons.
Any suggestions?

Thanks!

Very nicely done extension, thank you. Works great when viewing the notebook in Jupyter, but doesn't seem to work on export with the latest version of Jupyter.

First, it doesn't install; I think the location for extensions has moved to ~/.local/share/jupyter/nbextensions/. I installed it manually.

The toolbar buttons show up in the viewer, and clicking the toggle button hides code; but all of the export buttons redirect to the wrong URL. They're trying to go to /notebooks/mynotebook.ipynb/export/html, but it looks like the new location is /nbconvert/html/mynotebook.ipynb?download=true. At least that's what I get when I use the File -> Download As menu.

Speaking of which, when I do Download As HTML, the inputs aren't hidden.

OK, I'll try the nbconvert command line. Same problem; no hidden inputs. Only if I View -> Cell Toolbar -> Hide Code and then manually check 'Hide Code' for each cell and then save the notebook does it work, and then only on the command line (not the in-viewer export).

Bonus issue: when I try jupyter-nbconvert --to hide_code_latexpdf, I get ImportError: No module named HideCodeLatexPDFExporter (which does seem to be nonexistent).

Here's what I'm running.

pip uninstall hide_code does not uninstall the extension from jupyter

HideCodeLatexPDFExporter doesn't actually exist. Need to create the class as an extension of HideCodeLatexExporter.

Then I saw it was trying to access a python3. directory that didn't exist, make a soft link for it pointing to python3.5, re-ran the install, then it worked in jupyter just fine. Not sure if this is a bug or just an install note. Would've been nice it pip install behaved.

Hello,

I have python 2.7.11-1 on Ubuntu 16.04 and ipython-2.4.1-1 and jupyter (pip-installed).

I changed /home/user/.jupyter/jupyter_notebook_config.py from:
c.NotebookApp.notebook_dir = u''
to
c.NotebookApp.notebook_dir = u'/home/user/Workspace/Python'
so that it starts in such folder automatically. However this seems to break hidecode. When exporting a notebook (for example, with html), it gives a 500 Internal Server Error in the browser and the following output:

[I 12:47:03.980 NotebookApp] hide_code: Starting HTML export for None

    IOError: [Errno 2] No such file or directory: u'Untitled.ipynb'

It seems that hidecode cannot find the notebook file, at the time of execution of /usr/local/lib/python2.7/dist-packages/hide_code/hide_code.py. The argument args of the get method of HideCodeHTMLExportHandler does not seem to contain the full path to the notebook file, so I think that is the problem (the change applied to jupyter configuration file is not reflected here).

I don't know if this is intended behavior but I thought I would report it anyway, as it is a bit irksome. If there is anyway to fix it or a work around I would like to know.

Thank you. This extension is definitely useful.

I'm experiencing an odd behavior where once I've a non-None cell toolbar view selected, then toggle the hide/show code button, I can no longer switch cell toolbar view back to None. Here is a gif of an example:

Would be great if I could just export/convert notebook to html/pdf and have option to hide all code/prompts globally, instead of having to set which cell to hide cell by cell.

I sue the following code to show images in pdf.
However they just come up as OUT[*] in the pdf following a blank space.

from IPython.display import Image
Image(filename="image.jpg")

I really appreciate if I can get help to fix this.
Also if there is anyway to align the image in centre.

Hi,
I installed jupyter from Anaconda, and installed hide_code from pip.
hide_code isn't showing in jupyer neither in nbextensions or in view -> cell_bar. When i tried to use it from nbconverter i've got import error:
ImportError: No module named 'hide_code.HideCodeLatexPDFExporter'

Hi,
I tried the troubleshootings you suggested, but still get an 500 : Internal Server Error.

I want to uninstall hide_code, but I get another error message:
Starting hide_code.js removal...
No config directories contain "custom" folder. Trying Jupyter notebook module path...
Attempting to remove auto-loading for hide_code export handlers.
No hide_code server extensions to remove.

And in your wiki you state: hide_code.uninstall_bootrapped_files().
As I see from the attributes its: hide_code.uninstall_bootstrapped_files()

Looking forward to your help

Hey, I love your code hiding tool. I works great in the Browser and I can also produce pdfs from the command line. But I would really like to have the tex-file as well. I used
jupyter nbconvert --to hide_code_latex notebook.ipynb
and
jupyter nbconvert --to hide_code_latexpdf notebook.ipynb
but this only spits out the following:
Traceback (most recent call last):

I'd really appreciate some help.

when exit the hide code model, markdown cell had add additional cell like this:

raw markdown cell could not be hided in normal condition

could you fix this?
