Re: Has anyone experimented with using Python within LC?
This stack script hacks in support for arbitrary parameters to be passed in
easily.
You can, of course, do the same by including functions in the python
script, and then calling them in the shell statement. That's how I started
this journey, but it requires escaping things to make them
shell-compatible. This might be especially weird to do because of python's
flexible handling of double and single quotes.
This way the data can be passed in as you intend to use it, the only
limitation being that it all starts as text. Still, it works a treat.
Note: this doesn't check for file existence before writing them, although
it seems unlikely that anyone would have files named
e.g. 89914707287616_data.txt. Also, this doesn't re-use any files, so
repeated calls quickly pile up. This is far from a usable function.
The round-trip cost of doing things this way is maybe something like a
tenth of a second(?) so this is likely only for when you have a lot of
backend processing to do.
local fnb
function pythonFile p
put the filename of this stack into fp
set the itemdel to "/"
if fnb is empty then
put the long seconds into fnb
replace "." with empty in fnb
delete char 1 to 2 of fnb
end if
if paramCount() > 1 then
put "exData = {}" & cr into fileHeader
repeat with i = 2 to paramCount()
add 1 to fnb
put fnb & "_data.txt" into fn
put fn into item -1 of fp
put param(i) into url ("file:" & fp)
put merge("with open('[[fp]]', 'r') as f:[[cr]]") after fileHeader
put merge("exData[ [[i - 2]] ] = f.read()[[cr]]") after
fileHeader
end repeat
put fileHeader & cr before p
end if
add 1 to fnb
put fnb & "_temp.py" into fn
put fn into item -1 of fp
put p into url ("file:" & fp)
return shell(quote & "/Users/gcanyon/opt/anaconda3/bin/python" & quote
&& quote & fp & quote)
end pythonFile

Re: What is your best practice for setting a script in a script?
I wanted to ask why as well. You can put all the scripts necessary in a card, and if you need to know the actual object the user interacted with use the target command. Eg. Local lTargetID On mouseUp Put the long id of the target into lTargetID /* Your script here */ End mouseUp Bob S > On Jul 20, 2023, at 5:52 PM, Richard Gaskin via use-livecode > wrote: > > Paul Dupuis wrote: >> So in the instances where you have a script that creates an object >> and then sets the script of that object (example below), what is you >> best practice for having the script in a script and still be readable? > > Why? > > Among other concerns (robustness, debugging, maintenance), setting the script > of an object requires turning off script encryption. > > Dick Kriesel wrote: >> > > Hi, Paul.

Re: What is your best practice for setting a script in a script?
As some people on this list and the forums have explored in the past, I have a interest in creating a Livecode application (stack) entirely from a (text only) single script. So there are initially no Livecode objects to place a behavior script in. There are initially no buttons, fields, cards, stacks, or anything else. Yes, one of the values of Livecode is an interactive IDE for UI design (and refinement), but for this specific interest, it is all about creating the UI - in fact the whole app - from a single script. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: What is your best practice for setting a script in a script?
Paul. I assume you have a blueprint of what will become a stack with at least one card? And that stack will possibly contain other cards, controls, scripts and behaviors? But since all objects have properties, including scripts, and since LC has the “create” command, whatever you want to do seems straightforward, if not simple. You must have the IDE open to even start, of course, so you are already “in” LC. Why not just do it the old fashioned way? The end result will be a stack, correct? What is the advantage of not starting with a stack?

Re: What is your best practice for setting a script in a script?
Way back when (in the metacard era) I wrote code to create an XML representation of a stack, and build a copy of the stack from that XML file. Oh, I just checked and I still have a copy of the file. It almost certainly does not address all the nuances that have been added since then -- behaviors, widgets, and more -- but if you want a copy you're welcome to it. gc On Fri, Jul 21, 2023 at 9:12 AM Paul Dupuis via use-livecode < use-livecode@lists.runrev.com> wrote: > As some people on this list and the forums have explored in the past, I > have a interest in creating a Livecode application (stack) entirely from > a (text only) single script.

Speed Improvements
Hi all. I put a compiled version of Forms Generator 8 on a PC recently, and I would like to say that the speed improvements are very substantial from what I was experiencing in the past. SQL queries as well as file operation seem to be almost as fast as on my MacOS laptop. I would not hesitate to distribute a Windows app now, whereas before I would have been hard pressed. I will say that I streamlined my code to ensure I was not inadvertently re-querying for the same data, and the VM I am running it on has been migrated to another server, but even still I had tested on new PCs with SSD drives in the past and was getting disappointing results, whereas now I can hardly blink and a full query dataset is loaded and displayed. Kudos to the dev team!

Question re download timeout setting
Folks: Sorry for the trivial question, but.. I have an app on my iphone that I am updating from a several years old app the previously worked on an older version of livecode. It needs to access a mysql database on the internet. It works fine when there is internet service. I test access by downloading a file with a simple text code. If there code is returned in the message, I continue accessing the database. However, when there is no internet, the "put URL” command seems to hang forever. I’ve looked for a way to set the timeout for an internet command, but…. can’t,. Could you direct me to a simple explanation about how to set a reasonable internet not connected message? Thanks, Bill put "https://"&theURL&"/test.html"; into theURL put URL theURL into tOutput—if the request times out, the output is not received. if tOutput contains "AB7699HEYIMHERE” then —code received, internet access is successful return true else return false end if ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: Has anyone experimented with using Python within LC?
Hi Geoff
Sorry for not replying earlier but looks like you've got it sorted. I did a bit
on this years ago and am contemplating it again. Just looked for my old stack
and see this script for running a python script and putting the output into the
"output" fld:
on runPythonScript pScript
put the tempname &".py" into tFile
put pScript into URL ("binfile:" & tFile)
put shell("" && tFile) into fld "output"
end runPythonScript
Was starting to provide an interface for experiment parameters for the scripts
I was running (for some Turi ML classifications) but the project paused...
cheers
Alan
