In ArcMap when I set the Python script editor to Notepad++ (C:\Program Files (x86)\Notepad++\notepad++.exe) and open a script tool from a toolbox in Catalog with right click > edit, the currently open notepad++ opens a new tab in the existing notepad++ instance.
HOWEVER, in Pro 2.5, Pro opens a new instance instead of using the existing one.
Note the two instances of Notepad++ below (two windows):
Not such a big deal for notepad++ because it launches so fast, but I really like Wing and it's really slow if I have to launch it each time I edit.
Is this because my Notepad++ is 32 bit? Or is this symptom of the multi threaded nature of Pro?
Update Submitted to support Esri Case #02595592 - ArcGIS Pro editor opens in new instance
Yes. Did not help.
I downloaded the 64 bit version of NotePad++
Opened Notepad++ x64.
Opened Pro, went to backstage. Set the 64 bit version to be the editor in Pro
Then in the Catalog window I right-click > Edit a script in a toolbox I get a new instance of NotePad++ x64, does not open a new tab in the editor like ArcMap does.
plus many more on Dr Google search using 'notepad++ new instance'
Sounds like it isn't the default behaviour if your settings are like this
Why does this work in ArcMap but not in Pro without any special settings?
UPDATE Note, this did not help. I made the setting, still getting new instances.
Dan, have you actually tested this and gotten it to work or are you just posting me links?
I am going to ask tech support and report back.
I use Spyder and haven't used ArcMap in years... just looking for possible checks....
I will cease then
I do know that when I open a *.py it doesn't launch a new instance, but I use it as a text editor and not a python ide
Hi Curtis, I tested the workflow you gave above and was able to reproduce the issue. I am not sure if this is something expected or perhaps an equivalency bug, but I'll own your case Support side and we can go from there!
