LeoWapp: Leo in a browser?

[Viktor Ransmayr]

Hello Edward,

LeoWapp is announced as one of the main new features for Leo 5.9.

Where can I find a description how to use it?

In my case the current defaults would be Windows 10 as the OS and Firefox as the Web Browser.

With kind regards,

Viktor

leo --no-splash --no-plugins --gui=browser:firefox-browser <path to your .leo file>

The actual code is in leo/plugins/leoflexx.py.  At present, the docstring contains:

QQQ

flexx.py: LeoWapp (Leo as a web browser), implemented using flexx:
https://flexx.readthedocs.io/en/stable/

This file is the main line of the LeoWapp project.
https://github.com/leo-editor/leo-editor/issues/1005.

See #1005 for a status report and list of to-do's.

# Prerequisites

Install flexx: https://flexx.readthedocs.io/en/stable/start.html

# Running stand-alone

You can run leoflexx.py in stand-alone mode from a console:

    python <path to>leoflexx.py --flexx-webruntime=firefox-browser

The --flex-webruntime command-line arg is optional. If omitted, you'll use
the webruntime environment.

When running stand-alone, the startup code uses Leo's bridge module to load
unitTest.leo.

# Running as Leo's gui

You can also run leoflexx.py as Leo's gui:

    leo --gui=browser
    leo --gui=browser-firefox-browser
   
# What you should see
   
However you start leoflexx.py you should see the flexx (Tornado) server
start up in the console.

Something that looks like Leo should then appear in the browser. Everything
you see is real, and most of it is "live".

QQQ

HTH.

What did I do wrong - or - what additional information do you need to put me on track?

You're welcome.  Your question reminded me that the documentation for LeoWapp was not easy to find.  And it was obsolete.  Recent revs bring the docs up to date.

> I receive the following error, when I attempt to execute

  python ...leo/plugins/leoflexx.py

This stand-alone operation was for testing only.  Please try one of these:

   leo --gui=browser
   leo --gui=browser-firefox-browser

Here are the updated docs in LeoDocs.leo:

QQQ

https://github.com/leo-editor/leo-editor/issues/1005

LeoWapp (Leo as a web browser), implemented using flexx:
https://flexx.readthedocs.io/en/stable/

Start Leo using the --gui=browser option. Like this::

    leo --gui=browser
    leo --gui=browser-firefox-browser

The code is in leo/plugins/leoflexx.py, but this is not a plugin.

Prerequisites

Install flexx: https://flexx.readthedocs.io/en/stable/start.html

What you should see
   
You should see the flexx (Tornado) server start up in the console. Something that looks like Leo should then appear in the browser. Everything you see is real, and most of it is "live".

HTH. Please feel free to ask more questions.

This is flexx issue #555.  The fix, presumably, is to upgrade to the latest version of flexx.

[Viktor Ransmayr]

Hello Edward,

Yes, I can confirm, that this was the problem.

I was initially using flexx in version 0.7.1.

After upgrading flexx to version 0.8.0 I tried out "leo --gui=browser-firefox-browser" and

• http://localhost:49190/LeoBrowserApp/

displays the 'workbook.leo' outline in a new FF-Tab ...

Thanks a lot again for your support !

With kind regards,

Viktor

You're welcome. I'm glad the upgrade worked.

Hello Edward,

I've now found some time to 'play' with LeoWapp a bit - and - are now quite surprised that I'm not able to enter any command in the minibuffer :-(

Is this supposed to work - or - is this a current limitation of LeoWapp in 5.9b2?

With kind regards,

Viktor

PS: I experience the same behaviour when using Google Chrome - as well as - Mozilla Firefox as the web browser in a Windows 10 (1809) environment ...

I've just created #1131 for this.  There used to be some hacks relating to minibuffer commands.  I'm not sure what is supposed to happen.

Hello Edward,

Please let me know, if there's something I can do/ test ...

[Viktor Ransmayr]

Hello Edward,

I tried the "devel" branch of Leo from GitHub - and - installed it successfully via "pip install https://github.com/leo-editor/leo-editor/archive/devel.zip".

I can now enter commands in the minibuffer - but - all/ most of them don't work ...

Where are the current limitations of LeoWapp documented?

With kind regards,

Viktor

In info and bug issues: here.

Let me know if you would like more documentation on a particular topic.

Clones are working in LeoWapp but there appears to be no visible indication that a node is cloned. Is there any plan to show a small red clone arrow in the icon box? 

find-next-clone command works, and using Alt-n key press works for 'Go to next clone'

I've just added this to the to-do list in #1005, but it may never happen.  For now, I'm interested in real bugs.  Note that #1005 is closed.

The new command  restart-leo   works when running LeoWapp.
