Running Python in Atom.io in Windows

June 25th, 2015

I already hate Python, but their "IDE" makes it worse.  Fortunately, Atom.io can fix the IDE problem.

Atom.io is a Github product that whips the IDLE Python's ass.  It's not actually an IDE, it's  a text editor, but it's a text editor on steroids.

I stumbled upon a plugin for Atom to run various languages right in the window, including Python.  The problem is that it doesn't work right out of the box in Windows.  Fixing this is easy:

  1. Go to File - Settings (you can also press CTRL+,)
  2. Select Install
  3. In the search box, type "script" and it should come up after a few seconds
  4. Click install

Once it is installed (which should take less than a minute on a modern Internet connection), you will need to update the startup script to fix the path.  To do that:

  1.  Go to File - Open Your Init Script
  2. Add the following line

process.env.path = ["C:\Python27\ArcGIS10.2",process.env.PATH].join(";")

NOTE: I'm using the ArcGIS-bundled Python - you may need to fix that path!

Once the init script is updated, close and re-open Atom, and you should be able to select Packages - Script - Run Script (or press CTRL+SHIFT+B) to run a Python script.

Python and Cube

December 19th, 2010

One of the advantages of the ESRI ArcGIS Framework is that you can write Python scripts that do GIS things and run them from Cube.  Even better, Cube uses the Geodatabase format, so you can store and retrieve things from there.

The first thing that is needed is a python script.  The below is an example that we're not using at the moment, but it merges multiple transit line files together.

import arcgisscripting, sys, os
gp=arcgisscripting.create()

gp.AddToolbox("C:/Program Files/ArcGIS/ArcToolBox/Toolboxes/Data Management Tools.tbx")

print sys.argv

input1=sys.argv[1]
input2=sys.argv[2]
output=sys.argv[3]

in1=input1+input1[input1.rfind("\\"):]+"_PTLine"
in2=input2+input2[input2.rfind("\\"):]+"_PTLine"

input=in1+';'+in2
input=input.replace("\\","/")
output=output.replace("\\","/")

print input
print output

if gp.Exists(output):
    gp.delete_management(output)

#input=input1+"_PTLine" +';'+input2 +"_PTLine"

gp.Merge_management(input,output)

print gp.GetMessage

del gp

To call this, we add the following in a Pilot script:

*merge.py {CATALOG_DIR}\Inputs\Transit.mdb\Routes1 {CATALOG_DIR}\Inputs\Transit.mdb\Routes2 {CATALOG_DIR}\Inputs\Transit.mdb\RoutesCombined

This makes it easy to create geoprocessing steps in ArcMap, export them to Python, and call them from the model.

Getting GoogleCL to Download Drawings

October 20th, 2010

While looking into backing up my Google Docs, I realized that GoogleCL is not backing up drawings.

Fixing this requires a few minor modifications to the source in {download}\src\googlecl\docs\base.py (where {download} is where you downloaded the files}.

The first fix is in the try block on line 51.
was:

from gdata.docs.data import DOCUMENT_LABEL, SPREADSHEET_LABEL, \
                              PRESENTATION_LABEL, FOLDER_LABEL, PDF_LABEL

To:

from gdata.docs.data import DOCUMENT_LABEL, SPREADSHEET_LABEL, \
                              PRESENTATION_LABEL, FOLDER_LABEL, PDF_LABEL, DRAWING_LABEL

Then, beginning on 52 (the except ImportError block), it should include DRAWING_LABEL = 'drawing' as below:

except ImportError:
  DOCUMENT_LABEL = 'document'
  SPREADSHEET_LABEL = 'spreadsheet'
  PRESENTATION_LABEL = 'presentation'
  DRAWING_LABEL = 'drawing'
  FOLDER_LABEL = 'folder'
  PDF_LABEL = 'pdf'

Then, on line371, the following needs to be added before the 'else':
except ImportError:

elif doctype_label == DRAWING_LABEL:
      return googlecl.CONFIG.get(SECTION_HEADER, 'drawing_format')

Finally, in your .googlecl file (mine is under my "profile drive" because of our network settings, your mileage likely will vary, so you'll have to search for it), open config in any text editor and add the following in the [DOCS] section:

drawing_format = png

Note: while you're at it, you might want to change document_format = txt to document_format = doc

That's it. Now if you run 'google docs get .* ./backup', you get the drawings as well.
