Never finds the config.ini. Always claims grin3 not installed even though it is and the config.ini file exists. Repo code has the same issue as the book code.

Hmmm. Works on Linux (Xubuntu 18.04) and Windows 7. I will have to try this on my Mac later

Works on my Macbook Pro 10.14.4, Python 3.6.4. I do see this in stdout:

objc[11673]: Class FIFinderSyncExtensionHost is implemented in both /System/Library/PrivateFrameworks/FinderKit.framework/FinderKit (0x12a2df3c8) and /System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride (0x132108f50). One of the two will be used. Which one is undefined.

However, this error or warning does not seem to affect the running of the program at all.

Are you sure you are installing grin3 ?

Looks like my warning has something to do with Tkinter - jarvisteach/appJar#285

I don't know why it shows up when running wxPython, but that thread mentions that PyQt5 is also causing that error to pop up, so maybe it just has something to do with GUI toolkits in general. Doesn't seem to affect anything though.

Hmmm. I will have to try creating a virtualenv then when I get a chance. Not sure why that would happen in that scenario though

I created a virtualenv using Python's venv module. I installed wxPython, PyPubSub and ObjectListView in it and the text search code worked fine for me.

I hate to ask this, but could you try with Python 3.6? I wonder if there is some weird incompatibility with 3.7. I don't have 3.7 on my Mac at the moment to test with.

Windows 10 appears to work wit Python 3.7, although I am seeing this error in stdout:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "c:\Program Files (x86)\Python37-32\lib\threading.py", line 917, in _bootstrap_inner

    results[current_key].append(line)
KeyError: ''

I still get search results though.

I went ahead and fixed the issue I mentioned finding on Windows 10

FYI: I added Python 3.7 to my Mac and ran this code. I do get an error now that does not appear in 3.6. However, it is different from yours:

This appears to be a grin bug, not one with my code. I do get some search results returned regardless of the error, although I don't know if I am getting all the results I should.

Just downloaded the code for this same project and am trying to run it under VSCode 1.74.0 on Win10.
The problem I am running into is that selecting the grin.exe in the preferences dialog browser file selector never shows up in the preferences text control and hence I can never search for anything since the Save operation always fails with "Grin location not set!"
FWIW, the grin location is: C:\Users\arnold\AppData\Local\Programs\Python\Python39\Scripts\grin.exe
