mwxlib

Welcome to mwxlib project! Python package based on matplotlib/wx and wxPython shell extension library

See Demo Script and Gallery.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

• Python 2.7 (PY2 support has ended since 0.50)
• Python 3.5 (PY35 support has ended since 0.70)
• Python 3.7 (PY37 support has ended since 0.80)
• Python 3.8 -- 3.9 (Deprecated since 0.90)
• Python 3.10 -- 3.12
  • wxpython >= 4.2.2 (recommended)
  • numpy
  • pillow
  • matplotlib
  • opencv-python
• Python 3.13
  • There are some bugs in mwxlib that remain unfixed.
  • A version of wxpython for PY313 has released on PyPi.
    • You can also download the snapshot from https://wxpython.org/Phoenix/snapshot-builds/,

Installing

To install, type:

pip install mwxlib

To install latest version from GitHub, type:

pip install git+https://github.com/komoto48g/mwxlib.git

How to use

mwx.deb is wx.py.shell-base inspector used for debugging in the target process.

>>> import mwx; mwx.deb()

📝 mwxlib creates "~/.mwxlib/" in your HOME directory. This includes history, logs, dump files used to check when an error occurs.

📝 At the first startup, it takes some time to collect module information and create a dictionary file. The collected module name is used for completion at the time of input in the shell. (If you start the shell while pressing [C-S-], the dictionary file will be recreated)

As you are diving into the python process, you can watch, inspect, and debug the target.

Enjoy diving!

Uninstalling

pip uninstall mwxlib

Features

The animation shows how the Nautilus works, which is embedded in a simple PyEditor app.

As you are diving into the python process, you can watch, inspect, and change everything in the target.

Nautilus in the Shell

The framework has an extended class based on wx.py.shell.Shell named Nautilus, which has the following features:

1. Auto-completion and apropos functions are reinforced.
   • [1] history-comp-mode
   • [2] word-comp-mode
   • [3] apropos-comp-mode
   • [4] text-comp-mode
   • [5] module-comp-mode
2. Magic syntax.
   • [ ` ] quoteback
   • [@] pullback
3. Powerful inspectoin utilities.
   • Filling
   • InspectionTool
   • Ghost in the shell

All objects in the process can be accessed using:

    self : the target of the shell,
    this : the module which includes target.

To include the shell in your wxPython application:

>>> self.inspector = mwx.ShellFrame(self, target=self)

Autocomp key bindings

    C-up : [0] retrieve previous history
  C-down : [0] retrieve next history
C-j, M-j : [0] tooltip of eval (for the selected or focused word)
C-h, M-h : [0] calltip of help (for the selected or focused func)
     TAB : [1] history-comp-mode
     M-p : [1] retrieve previous history in comp-mode
     M-n : [1] retrieve next history in comp-mode
     M-. : [2] word-comp-mode
     M-/ : [3] apropos-comp-mode
     M-, : [4] text-comp-mode
     M-m : [5] module-comp-mode

• All completions [1--5] are incremental when pressed any alnums, and decremental when backspace.
  See key bindings for more information.

Magic syntax

• quoteback : x`y --> y=x | x`y`z --> z=y=x

• pullback : x@y --> y(x) | x@y@z --> z(y(x))

• apropos : x.y? [not] p => shows apropos &optional (not-)matched by p:predicates equiv. apropos(y, x [,ignorecase ?:True,??:False] [,pred=p]) y can contain regular expressions. (RE) \a:[a-z], \A:[A-Z] can be used in addition. p can be ?atom, ?callable, ?instance(*types), and predicates imported from inspect e.g., isclass, ismodule, ismethod, isfunction, etc.

• info : ?x --> info(x) shows short information

• help : ??x --> help(x) shows full description

• sx : !x --> sx(x) executes command in external shell

  Note: The last three (*) are original syntax defined in wx.py.shell, at present version, enabled with USE_MAGIC switch being on

built-in utilities

@p          : Synonym of print.
@pp         : Synonym of pprint.
@mro        : Display mro list and filename:lineno.
@where      : Display filename:lineno.
@info       : Short info.

Ghost in the shell

Ghost in the shell is the help system for divers, which is a notebook-style window consists of four editors:

• scratch buffer
  • a temporary buffer
• Help buffer
  • piping text from info(?) and help(??)
• Logging buffer
  • logging debug process and the input-history
