add a scripting console

[timmie]

Please consider adding an IPython console to the wxGUI for scripting in the future

[martinl]

Available as "Python shell" in wxGUI (see 6.4.3+). Closing this ticket.

Excuse me for pluggin in again on this. What do you think about making this shell IPython-aware.

So if a users has IPython installed, it would then offer all its comfort and capabilities (plotting, %magics, existing plugins, R-interface, etc.)

essentially i found it a really easy and effective way to use grass from a web page, but it runs pretty well also from localhost of course.

i'd love to write a grass gui plug-in to integrate the IPython Notebook inside the WX-gui in GRASS maybe a simple wx frame that embed an http link to where the notebook is running + an init script to lunch the notebook before to start to coding something ( i'm pretty new to WX and its "grass internals" ) i was wondering if there is any interest on doing this from the GRASS gui guru … :) that can help me to get started

So does this mean agreement or disagreement?

the notebook is a beast that could not get integrated. We would rather need to create a set of %magics to open the wxGui from within the IPython Notebook to

• get the power of scripting with GRASS, R, Scipy etc.
• use the power & comfort of GRASS wxGUI for display and interaction.

=> this would be a different enhancement request.

But here' a gui example: ​https://github.com/ipython/ipython/blob/master/examples/lib/ipkernel_wxapp.py

This console is based on qt. It would be possible to call it and use it as a separate window. However, so far I was not able launch it from wxGUI because of various errors. Also it seems that the console (from the example above) does not quit with the wx app. Maybe someone will be more lucky.

I haven't succeeded in launching wxGUI from IPython either. The GUI freezes. The ​example works at least, so it should be possible to make it work.

I think you are talking of the IPython QT Console.

Ok, since this ticket here is closed, please follow up on the new enhancement ticket:

use IPython for python Shell in wxGui if installedhttps://trac.osgeo.org/grass/ticket/1922

Annakrat that is correct, those examples are for embedding the IPython *kernel*, not UI.

IMHO, try to embed the notebbok is worth to try (much powerful and easier to implement than the standard IPython shell) in wx 2.9 a simple code like :

import wx
import wx.html2

app = wx.App(False)
frame = wx.Frame(None, -1, 'A Simple Frame')
browser = wx.html2.WebView.New(frame)
browser.LoadURL("http://IP:PORT/NoetebookName.ipynb")
frame.Show()
app.MainLoop()

will open a wx frame within the notebbok. # the problem here is wx2.9 ...

We can have a "notebook dashboard" written in a WX frame as part of the grass wx gui, something like :

#!/usr/local/bin/python

import sys

import wx

import wx.html2

class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, -1, title,
                          pos=(150, 150), size=(350, 285))
        menuBar = wx.MenuBar()
        menu = wx.Menu()
        menu.Append(wx.ID_EXIT, "E&xit\tAlt-X", "Exit")
        menuBar.Append(menu, "&File")
        self.SetMenuBar(menuBar)
        self.CreateStatusBar()
        panel = wx.Panel(self)
        text = wx.StaticText(panel, -1, "Notebook Browser")
        text.SetFont(wx.Font(14, wx.SWISS, wx.NORMAL, wx.BOLD))
        text.SetSize(text.GetBestSize())
        
        NoetebookName_btn = wx.Button(panel, -1, "NoetebookName")
        self.Bind(wx.EVT_BUTTON, self.showBrowser, NoetebookName_btn)
        sizer = wx.BoxSizer(wx.VERTICAL)
        for ctrl in [text, browser_btn]:
            sizer.Add(ctrl, 0, wx.ALL, 10)
        panel.SetSizer(sizer)
        panel.Layout()
        
    def showBrowser(self, evt):
        app = wx.App(False)
        frame = wx.Frame(None, -1, 'A Simple Frame')
        browser = wx.html2.WebView.New(frame)
        browser.LoadURL("http://IP:PORT/NoetebookName.ipynb")
        frame.Show()


class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame(None, "Simple wxPython App")
        self.SetTopWindow(frame)
        frame.Show(True)
        return True

if __name__ == '__main__':
    app = MyApp(redirect=False, clearSigInt=False)
    app.MainLoop()

Instead of a single button, we'll have (auto generated) buttons for each notebook avalable in the IPython notebook dir, and open a new tab in the wx-dashboard-frame when a button is pressed (notebook dir is in the ipython_notebook_config.py "c.FileNotebookManager.notebook_dir")

Hope make sense ... if looking for an "ancient" wx-gui for ipython .. i found something here ​here but is really old ...
