doesn't parse the example file

[az143]

i cloned the repository last week, head is at 3009b0d, and it doesn't work at all, not even on the provided example file:

calling python3 TFTTool.py -i Example/HSV\ Test.tft
results in
Warning: No instruction set found that matches editor version nxt-1.61.1. You won't be able to decode any usercode.
...
Exception: A valid instruction set is required to decode the usercode.

the parent revision c96ffd6 works.

TL;DR that old one didn't complain but it's not really trustworthy either. I should've updated the example files I guess. Furthermore I think it'd be a good idea to add an option to list the supported editor versions.
In the meantime you could change the editor version with TFTTool and rerun it but - again - the result will be garbage because Nextions instruction encoding sucks (see below).

Long version:

The reason is that the decoding is much more complicated than what I thought since it's been designed with absolutely zero compatibility in mind. Instructions literally get their opcode from the order in which they appear in the editor source code. Whenever that order changes (added instruction, removed instruction, randomly moved one around), it breaks compatibility. Also, the order is specific to every model series. That means that for every nextion and tjc editor version as well as for every single series of screens the encoding of the instructions changes. Thus for every single case it needs to be determined and added to TFTTool for proper decoding.

I originally didn't know that and thus hardcoded the values from editor v1.61 and different device series into TFTTool. Thus it worked properly for some v1.61.1 files but was neither reliable nor compatible with anything else. The latest push "fixed" that by adding awareness of the editor version, including proper decoding of the latest versions as well as v0.58 since I needed that one, too. The decoding list of the previous version of TFTTool vanished because it was neither complete nor trustworthy. Determining the full list is more work than I was willing to spend on that old version.

If you want or need support for that version (or any other one), you can join the UNUF discord and we can discuss stuff there: https://unofficialnextion.com/t/welcome-to-the-unofficial-nextion-tjc-user-forum/8

Kind regards,

Still no solution...
