running python script with system arguments from applescript

Cannot peer into your Python code, but for a), change to this:

& quoted form of strNote.

If I use your syntax with my change on the following Python code, I get the original string back to AppleScript.

#!/usr/bin/env python

#

import sys

mystr = str(sys.argv[1])

print("{}".format(mystr))

The strange thing is, that I see in the applescript results window the result of the print statements in the python script, but no output is generated

What is the output of the script? Is is just a return of something?

If so, try:

set results to do shell script "cd /Users/thatsme/Library/Scripts/myfolder; python my_python_file.py " & quoted form of strNote

display dialogresults

I assumed that Carlossos would have understood my implicit suggestion of setting a variable (and optionally its display) if that were a scripting goal.

Opps, didn't see that in your response (now, where's my coffee 🙂)

I know. I am about to mill and brew some breakfast blend. 😉

- the string that I am trying to pass as an argument is a string that is a valid latex math expression

- so when I say

set strNoteQ to quoted form of lstNote

then I get

error "Can’t get quoted form of {\"1+1=2\"}." number -1728 from quoted form of {"1+1=2"}

How did you set lstNote and what does it "look" like? (run display dialoglstNote)

Using do shell script is different than running a command in terminal. Environment variables (and in particular the $PATH variable) may be different, and other things that you expect in a terminal.app shell may not be present in a do shell script shell. Make sure that you spell out full paths to everything in both the applescript and the python script.

Also, you may be having trouble with applescript quoting. you want the string you feed into applescript to look like "{\"1+1=2\"}" or maybe "'{\"1+1=2\"}'". Applescript will interpret this - {"1+1=2"} - as a list that contains the string "1+1=2", not as the latex expression you think you're entering.

error "Can’t get quoted form of {\"1+1=2\"}." number -1728 fromquoted formof{"1+1=2"}

lstNote is a list. You can;t get the quoted form of a list.

Either make lstNote a simple string

set lstNote to "1+1=2"

or

get the item out of the sting

set lstNote to {"1+1=2"}

set strNoteQ to quoted form of item 1 of lstNote

Message was edited by: Frank Caggiano - ah latex so you really want the string {"1+1=2"} in that case you need to escape the {}'s

set lstNote to "{\"1+1=2\"}"

As there is no user interaction in your AppleScript yet, is this just a test harness until you get the passed LaTeX string working? Any reason why you couldn't run AppleScript (HERE text) as a subprocess from within Python, and get the string back directly from the subprocess into Python?

set strNoteQ to "1+1=2" as text

If this is supplied as an argument to Python in the do shell script as just & strNoteQ, it goes into Python as though it were typed on the Python command line in the shell. Tested.

Hello

I'd guess it's PATH issue. The "do shell script" command does NOT inherit bash environments unless you explicitly source the profile.

Try something like this, provided that your environments are set in ~/.bash_profile:

set s to "1+1=2"
do shell script "source ~/.bash_profile
cd /Users/claushaslauer/Library/Scripts/OO_latex
python create_latex_pdf.py " & s's quoted form

Didn't know about source. I always gave the full path. source is better 🙂
