Thanks for trying to help.
I have file named config.json
and main.js
In the JRNL directory.
I don't think I have any "appdata" folder since I'm on Windows 7 and not Windows 10.
I think Windows' folder structure is mostly the same between 7, 8, and 10. Try pasting %appdata%\jrnl into Windows Explorer's address bar. That should get you into the right directory with the Preferences file. Opening the Run dialog (Windows key + R) and pasting the same thing in there should also work.
Ok. I didn't know about the "appdata" folder, and its purpose.
The "Preferences" file looked like this:
{"spellcheck":{"dictionaries":["en-US"],"dictionary":""}}
I tried your suggestion:
{"browser":{"enable_spellchecking":false},"spellcheck":{"dictionaries":["en-US"],"dictionary":"","use_spelling_service":false}}
and this:
{"spellcheck":{"enable_spellchecking":false},"dictionaries":["en-US"],"dictionary":"","use_spelling_service":false}}
..but I didn't make it work.
I have started to look for other journaling software that are also minimalist.
I found s Rednotebook(free), and Journal/Simple Journal here on Itch.
I liked JRNL the best. But I can´t stand it when I can't remove the spellcheck.
Do you have any suggestion for other similar programs?
Strange. That should've disabled spellchecking unless I made a mistake with the code I gave you. Did you close JRNL before editing the Preferences file, or restart it afterwards?
For what it's worth, the original version of my file looked identical to yours. I deleted en-US from the dictionaries list, and JRNL added a few other spellcheck-disabling entries on its own when I next started it. You could try one last thing and replace the contents of "Preferences" with the following (make sure you've quit JRNL first):
{"spellcheck":{"dictionaries":[""],"dictionary":""}}
If that still doesn't work, there's a spellCheck attribute in JRNL\resources\app\summernote.js you could try setting to false. I'm hesitant to test it on my end for fear of possibly breaking something, but hey, might work for you.
Hopefully the author will come along and add a spellchecker toggle to the configuration menu, as well as fix that other entry-wiping bug I mentioned in another comment below.
Unfortunately, I don't really know of any alternative journal software, as I only started journaling again after discovering this app through the Ukraine bundle.
