How can I associate an extension of a file to an program in Windows CE? It's so boring to run my Python programs using cmd. If I associate Python with my **.py* files I'm going to run my program faster. Thanks!
I was searching in the Python files under my Windows CE and i found a simple code to do this, and i tweaked it to be better:
#
# Setup the registry to allow us to double click on python scripts
#
from _winreg import *
print "Setting up registry to allow\ndouble clicking of Python files to work"
#
# Create the registry entries for ".py" and ".pyc" extensions
#
for Name in (".py", ".pyc"):
Key = CreateKey(HKEY_CLASSES_ROOT, Name)
SetValue(Key, None, REG_SZ, "Python.File")
CloseKey(Key)
#
# Create HKEY_CLASSES_ROOT\Python.File\Shell\Open\Command = "\Program Files\Python\Lib\Python.exe" "%1"
#
Key = CreateKey(HKEY_CLASSES_ROOT, "Python.File")
for Name in ("Shell","Open","Command"):
New_Key= CreateKey(Key, Name)
CloseKey(Key)
Key = New_Key
SetValue(Key, None, REG_SZ, "\"\\Program Files\\Python\\Lib\\Python.exe\" \"%1\"")
CloseKey(Key)
import time
time.sleep(5)
This is the code, if you want you can use it to associate to other programs and other extensions.

I would like to know if it is possible to add a custom command to the GNAT Programming Studio (GPS)?
If the custom command is invoked (by a button in the menu bar or a keyboard shortcut) an external Python script should be called with the full/absolute path to the file that is opened and selected in the editor.
This is a quick-and-dirty script that might give some direction. I tested it on Linux, but it should also work on Windows. Change the action near the end to invoke the script you like. To actually use it, you must put it in the (hidden) .gps/plug-ins directory which can be found in your home directory. The actual action can be invoked from the context menu in the source code window.
run_my_script.py
"""Run Python Script
This plug-in executes a python script.

I have several Jupyter notebooks which perform analysis on datasets. Right now, a dataset is specified by its filename. Every time the user wants to perform analysis on a new dataset, she/he has to edit the appropriate line in the notebook and modify dataset path string. The datasets can be located in different directories. The notebooks can also be located in different directories. In each notebook I would like to provide a widget that allows the user to browse the remote file system and pick the dataset he/she wants to analyse.
Are there any open source projects that support the above functionality? I am looking for something that is still active/supported and has some basic documentation. I did quick search on Google and surprisingly I didn't find anything.
Then I realised that JupyterLab, the evolution of Jupyter, has something very similar to what I want. It already has a very capable file browser but it is a bit "isolated" from everything else.
Is it possible somehow to get the relative (to the currently opened notebook) path of the selected file in the JupyterLab file browser?
Thank you.
Here's code for a server-side file browsing widget. Only tested in regular Jypter notebook - not Jupyter Lab. Also, must use a fairly recent version. Hope this helps.
import sys
import os
import ipywidgets as ui
from IPython.display import display
class PathSelector():
def __init__(self,start_dir,select_file=True):
self.file = None
self.select_file = select_file
self.cwd = start_dir
self.select = ui.SelectMultiple(options=['init'],value=(),rows=10,description='')
self.accord = ui.Accordion(children=[self.select])
self.accord.selected_index = None # Start closed (showing path only)
self.refresh(self.cwd)
self.select.observe(self.on_update,'value')
def on_update(self,change):
if len(change['new']) > 0:
self.refresh(change['new'][0])
def refresh(self,item):
path = os.path.abspath(os.path.join(self.cwd,item))
if os.path.isfile(path):
if self.select_file:
self.accord.set_title(0,path)
self.file = path
self.accord.selected_index = None
else:
self.select.value = ()
else: # os.path.isdir(path)
self.file = None
self.cwd = path
# Build list of files and dirs
keys = ['[..]'];
for item in os.listdir(path):
if item[0] == '.':
continue
elif os.path.isdir(os.path.join(path,item)):
keys.append('['+item+']');
else:
keys.append(item);
# Sort and create list of output values
keys.sort(key=str.lower)
vals = []
for k in keys:
if k[0] == '[':
vals.append(k[1:-1]) # strip off brackets
else:
vals.append(k)
# Update widget
self.accord.set_title(0,path)
self.select.options = list(zip(keys,vals))

I want to put couple of cells with commands I need in almost every new notebook in every new notebook I create.
For example when I create a new notebook it should put a
%matplotlib inline
import matplotlib.pyplot as plt
in a cell by default but not execute it.
How could I set something like that up?
This will work for both terminal based IPython shell and Browser based Notebook:
Navigate to ~/.ipython/profile_default
Create a folder called startup if it’s not already there
Add a new Python file called start.py
Put your favorite imports (and custom functions may be) in this file
Launch IPython or a Jupyter Notebook and your favorite libraries will be automatically loaded every time!
Here is my sample for start.py:
Another Source
To define set of commands on default startup, you need to add the commands in the templete ipy_user_conf.py file in your ~/.ipython directory.
This module is imported during IPython startup. So you can easily do : import modules, configure extensions, change options, define magic commands, put variables and functions in the IPython namespace etc.
Here is the sample ipy_user_conf.py :
# Most of your config files and extensions will probably start
# with this import
import IPython.ipapi
ip = IPython.ipapi.get()
# You probably want to uncomment this if you did %upgrade -nolegacy
# import ipy_defaults
import os
def main():
#ip.dbg.debugmode = True
ip.dbg.debug_stack()
# uncomment if you want to get ipython -p sh behaviour
# without having to use command line switches
import ipy_profile_sh
import jobctrl
# Configure your favourite editor?
# Good idea e.g. for %edit os.path.isfile
#import ipy_editors
# Choose one of these:
#ipy_editors.scite()
#ipy_editors.scite('c:/opt/scite/scite.exe')
#ipy_editors.komodo()
#ipy_editors.idle()
# ... or many others, try 'ipy_editors??' after import to see them
# Or roll your own:
#ipy_editors.install_editor("c:/opt/jed +$line $file")
o = ip.options
# An example on how to set options
#o.autocall = 1
o.system_verbose = 0
#import_all("os sys")
#execf('~/_ipython/ns.py')
# -- prompt
# A different, more compact set of prompts from the default ones, that
# always show your current location in the filesystem:
#o.prompt_in1 = r'\C_LightBlue[\C_LightCyan\Y2\C_LightBlue]\C_Normal\n\C_Green|\#>'
#o.prompt_in2 = r'.\D: '
#o.prompt_out = r'[\#] '
# Try one of these color settings if you can't read the text easily
# autoexec is a list of IPython commands to execute on startup
#o.autoexec.append('%colors LightBG')
#o.autoexec.append('%colors NoColor')
o.autoexec.append('%colors Linux')
# some config helper functions you can use
def import_all(modules):
""" Usage: import_all("os sys") """
for m in modules.split():
ip.ex("from %s import *" % m)
def execf(fname):
""" Execute a file in user namespace """
ip.ex('execfile("%s")' % os.path.expanduser(fname))
main()
For more details, please refer the link : Customization of IPython.
I hope this is what you wanted to know.
JupyterLab
In a comment to one of the other answers, the OP pointed out the need to insert the actual code instead of having it load in the background. One way is to create a text keyboard shortcut by going to Settings -> Advanced settings editor -> JSON settings Editor and adding the following under User Preferences:
{
"shortcuts": [
{
"command": "apputils:run-first-enabled",
"selector": "body",
"keys": ["Alt I"],
"args": {
"commands": [
"console:replace-selection",
"fileeditor:replace-selection",
"notebook:replace-selection",
],
"args": {"text": "import pandas as pd\nimport altair as alt\n\n"}
}
}
]
}
This will insert the following snippet each time you press Alt + i in the notebook:
import pandas as pd
import altair as alt
# <-- Cursor placed here
More on text shortcuts in jupyterlab
IPython console
If you are interested in automatically importing commonly used libraries in the IPython console only so that they are there for interactive use, but not in the notebook to avoid issues with sharing notebooks lacking some imports, you can launch IPython like so (and set up an alias to not have to type this each time):
ipython -c "import pandas as pd; import numpy as np" -i
(This was what I was looking for when I originally found this question)
we have recently upgraded to oe rdbms 11.3 version from 9.1d. While generating
reports,i found the field value of a field comes as 2'239,00 instead of
2,239.00.I checked the format its >,>>>,>>9.99.
what could be the reason behind this?
The admin installing the database didn't to it's homework and selected wrong default numeric and decimal separator.
However no greater harm done:
Set these startup parameters
-numsep 44 -numdec 46
This is an simplified database startup example with added parameters as above:
proserve /db/db -H dbserver -S dbservice -numsep 44 -numdec 46
When you install Progress you are prompted for the numeric format to use. That information is then written to a file called "startup.pf" which is located in the install directory (C:\Progress\OpenEdge by default on Windows...)
If you picked the wrong numeric format you can edit startup.pf with any text editor. It should look something like this:
#This is a placeholder startup.pf
#You may put any global startup parameters you desire
#in this file. They will be used by ALL Progress modules
#including the client, server, utilities, etc.
#
#The file dlc/prolang/locale.pf provides examples of
#settings for the different options that vary internationally.
#
#The directories under dlc/prolang contain examples of
#startup.pf settings appropriate to each region.
#For example, the file dlc/prolang/ger/german.pf shows
#settings that might be used in Germany.
#The file dlc/prolang/ger/geraus.pf gives example settings
#for German-speaking Austrians.
#
#Copy the file that seems appropriate for your region or language
#over this startup.pf. Edit the file to meet your needs.
#
# e.g. UNIX: cp /dlc/prolang/ger/geraus.pf /dlc/startup.pf
# e.g. DOS, WINDOWS: copy \dlc\prolang\ger\geraus.pf \dlc\startup.pf
#
# You may want to include these same settings in /dlc/ade.pf.
#
#If the directory for your region or language does not exist in
#dlc/prolang, please check that you have ordered AND installed the
#International component. The International component provides
#these directories and files.
#
-cpinternal ISO8859-1
-cpstream ISO8859-1
-cpcoll Basic
-cpcase Basic
-d mdy
-numsep 44
-numdec 46
Changes to the startup.pf file are GLOBAL -- they impact all sessions started on this machine. If you only want to change a single session then you can add the parameters to the command line (or the shortcut icons properties) or to a local .pf file or to an ini file being used by that session.
You can also programmatically override the format in your code by using the SESSION system handle:
assign
session:numeric-decimal-point = "."
session:numeric-separator = ","
.
display 123456.999.
(You might want to consider saving the current values and restoring them if this is a temporary change.)
(You can also use the shorthand session:numeric-format = "american". or "european" for the two most common cases.)
Is there a way to set the compiler warnings to be interpreted as an error in the Arduino IDE?
Or any generic way to set GCC compiler options?
I have looked at the ~/.arduino/preferences.txt file, but I found nothing that indicates fine-tuned control. I also looked if I could set GCC options via environment variables, but I did not find anything.
I don't want to have verbose compiler output (which you can specify using the IDE) that is way too much distracting non-essential information, and I don't want to waste my time on reading through it.
I want for a compilation to stop on a warning, so code can be cleaned up. My preference would be to be able to set -Werror= options, but a generic -Werror will do for the small code size of .ino projects.
Addendum:
Based on the suggestion in the selected answer, I implemented an avr-g++ script and put that in the path before the normal avr-g++. For that I changed the Arduino command as follows:
-export PATH="${APPDIR}/java/bin:${PATH}"
+export ORGPATH="${APPDIR}/java/bin:${PATH}"
+export PATH="${APPDIR}/extra:${ORGPATH}"
And in the new directory extra in the APPSDIR (where the Arduino command is located), I have
an avr-g++ which is a Python script:
#!/usr/bin/env python
import os
import sys
import subprocess
werr = '-Werror'
wall = '-Wall'
cmd = ['avr-g++'] + sys.argv[1:]
os.environ['PATH'] = os.environ['ORGPATH']
fname = sys.argv[-2][:]
if cmd[-2].startswith('/tmp'):
#print fname, list(fname) # this looks strange
for i, c in enumerate(cmd):
if c == '-w':
cmd[i] = wall
break
cmd.insert(1, werr)
subprocess.call(cmd)
So you replace the first command with the original compiler name and reset the environment used to exclude the extra directory.
The fname is actually strange. If you print it, it is only abc.cpp, but its length is much larger and it actually starts with /tmp. So I check for that to decide whether to add/update the compile options.
It looks like you are on Linux. Arduino is a script, so you can set PATH in the script to include a directory at the beginning to a directory containing a program, avr-g++. Then the Java stuff should take the compiler from there, should it not?
That program then calls the normal /usr/bin/avr-g++ with the extra options.
One option you have is to compile your sketches from the command line. Take a look at this makefile.
