YAGL - Yet Another GRF Language (maybe)

[UnicycleBloke]

This is because the NewGRF specs have been extended. The code was recently updated by a kind contributor but I need to publish a fresh build. It's on my list but I've been busy of late. Sorry. I'll try to make time this weekend.

I have created a new release of yagl at https://github.com/UnicycleBloke/yagl/releases/tag/v1.2. GlobalSettings has a couple of properties which apparently did not exist when I wrote the code. I have updated the code to include these.

Please try this to see if it fixes the problem. If not, I would be very grateful if you could provide the offending NewGRF. I don't play OTTD at the moment and don't have any recent files. Bananas seems to list them all as available-in-game. I did try installing the game on Linux but was unable to work out where downloaded NewGRF files are placed in the file system.

It's been a while since I looked at this code. Hopefully all is well.

The source code for Drop JF Fork is here, it would be best to work from that.

Thanks for the link, kamnet. I tried out the new version and had indeed fixed the unknown property, but then there was another to fix... They were related to roadtype/tramtype translation tables. This is a feature introduced since I wrote the code. There are sure to be some others lurking here and there. It's easy to support new properties, but I haven't been proactive keeping up to date with the NewGRF specs. I hadn't really expected that people would use yagl for recent GRFs for which there is NML source.

I would like to bring the code up to date with the specs but I'm not sure when I'll find the time...

Hey @UnicycleBloke! Thanks for the YAGL tool! I used it to decompile the NewGRF "Larger ship" by Bilbo. Then I encoded the .yagl with with YAGL and tested in game. Worked fine BUT when uploading to BaNaNaS, BaNaNaS does not allow the upload and says "["File 'fast_ships.grf' failed validation", 'fast_ships.grf: Unexpected end-of-file.']" I have attached the .yagl file as well as the grf generated by YAGL.

To answer your question on Discord, yagl does support both Container1 and Container2 formats. I checked and you would only need to change one line in the YAGL code to change the format. I think someone suggested that BaNaNaS does not support Container1. The default in yagl is Container2.

The other thing I noticed while debugging is that the GRF version is given as GRF6. The default in yagl is GRF8. I have no idea what BaNaNaS expects in this regard, but maybe try GRF8.

Please let me know if making these changes fixes the issue.

Just switched to "Container2" and BaNaNaS was happy Thanks!
