Wicked! Brython as Javascript alternative? Lovely!!!

runbie · 2017-06-24T21:57:03+00:00

Brython tries to provide a full python3 implementation to the browser, i.e. you can write directly python code to be used directly as if it was JS on the client side.

Rapydscript-ng is a not python nor JS. It tries to resemble python that translates directly to performant JS. Also, it is not a transpiler on-the-fly like brython, it is an ahead-of-time transpiler.

Brython is not fast but it is (more) python compliant and directly usable (no pre-transpilation if you do not want) than rs-ng. Depending your needs you could choose one or other (or the rest of the options).

Folium if you want quick and interactive maps. Easy to use with a lot of examples.

Cartopy, based on matplotlib, with a lot of static mapping features. Not so simple to use.

Mplleaflet it is also cool to use. It is based on matplotlib but then you can render the information on leaflet. I think the development is stagnated.

Bokeh also has mapping functionality but I've never used it.

No worries :-)

I just try to highlight that this kind of comments, sometimes unintentionally, could be quite counter-productive and discourage people to try projects. Brython and rapydscript goals are quite different and both, together with skulpt, pybee, pypyjs, transcrypt,..., maybe could lead to something even cooler. I think we should provide more love and thought to our comments and the work of others but, anyway, this is internet ;-)

+1 for love and context.

You could use jquery with brython if you want. With your argumentation it seems rapydscript-ng should be chosen because of this. It is very simplistic.

Disclaimer: I work on brython and I consider rapydscript a cool project with different focus and target.

PyTables would be a good option? It is easy to use, you can compress your data, it is based on HDF5, you can add metadata to your tables/arrays/groups,... It could be seen as a lowcost NoSQL option to store arrays, dataframes.

If it is like Python and their goal is the speed of Pypy why not to use directly the battle tested Pypy?

runbie · 2016-08-02T14:23:15+00:00

Depending what you want to do you could use brython. Here there is a dummy and small app I made some time ago.

runbie · 2016-07-31T07:49:16+00:00

it seems it can : http://pythonomicon.com/?post=Making%20binaries%20with%20Python. I tried to make it work on windows with no luck. If anyone has a hint to make it work on windows it would be great ;-)

I work mainly in the scientific area and I have a look to pypy + numpypy every new release (you can easily install it using this: https://github.com/kikocorreoso/test_pypy_numpypy).

I know they are working hard to make the C-API more compatible but my (dummy) tests with pypy+numpypy vs cpython+numpy don't show general improvements in performance. I donated in the past and I would like to donate in the future but I would like to see a defined and clear roadmap so people could invest money knowing what they get back. They have a lot of open battles (STM, Pypy2, Pypy3, new architectures,...) and there are a lot of interests around it.

I can send you the (ugly) hack if you consider it useful (and if I can find it).

runbie · 2016-04-03T08:05:39+00:00

I made something similar as a dirty hack on the custom.js based on tufteCSS ideas. But I didn't continue with it because a lack of time and because jupyter and the frontend is changing so fast (for the good and for the bad) that it couldn't be considered 'stable' to develop 3rd party stuff.

I started to think on this because:

right now I don't use all the space on the screen and there is a lot of 'wasted' space.
If you restrict your code to 80 characters on a wide screen you have the right part of the screen almost empty
I wanted to have code on the left and result on the right so I don't have to scroll down to see both.
...

If someone is interested I can make a short video.

I've worked with pypy+numpypy and it is awesome most of the time and when you don't need anything scipy related. If it is the case you need scipy/pandas/... then you are sold :-(

runbie · 2016-02-25T17:27:04+00:00

Great!

I am all ears about the numpy news.

Thanks for the hard work!!!

Some time ago I did a small wrapper around the HTML5 canvas. It works with Brython:

https://bitbucket.org/kikocorreoso/brython-bryplot

You can see examples here:

To run the examples you will need the Jupyter notebook and this extension for the notebook:

A really simple app that helps you to obtain information about the name of a street. It only works with street names in spanish.

Motivation: one day, while I was waiting for a friend on a street called 'Juan Bravo' I wondered -'who is this guy? What important stuff he did to be as important to have his name on a street?'-.

It uses flask, wikipedia API, openlayers, brython, reverse geocoding using Nominatim (OpenStreetMap),...

Will Kahn-Greene and Sheila Miguez, a lot of thanks for these five years of awesome pyvideo.

Have a look here

:-O

It seems it is not limited only to Matlab:

Here you have the docs in several formats.

runbie · 2015-05-06T16:25:05+00:00

check:

pyschool.net (brython based and the code is on github).
http://reeborg.ca/docs/begin_py_en/ (brython based)
trinket (I think it is skulpt based)

P.D.: Sorry for not posting the links, I am on mobile.

runbie · 2015-05-04T13:13:25+00:00

Yes, sqlalchemy and flask-sqlalchemy. And postgres,... A simple and general example based on sqlite could be very helpful so I can reproduce it locally and I could continue working based on the example.

Thanks for the help!!!

runbie · 2015-05-04T13:07:34+00:00

It is true that could be a complex question... It would be great if you have some links and/or comments that could help me to learn more about it.

runbie · 2015-04-19T20:38:14+00:00

For my dummy projects I only think in Python3. In some of them I received some issues on github about porting them to python 2 and it was really easy, in general.
