Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

The TeboView importer has begun its life...

It'll take a few days probably before the first glimmers of an actual boardview will show up on the program but at least we're on a roll now.

Many thanks to you all - didn't take as long as feared, at least not for the initial attempts

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

So yeah, with the current python code:

cds2f_NSA911R0-0329.tvw seems to decode (but the next thing is unknown, so maybe…)

NSB241R10.tvw decodes but it only has one surface on the first layer.

cds2f_NSA912R10-0329.tvw fails to decode at the second Surface because there's an extra 4 bytes before the net ID:

Ok, took some time to write up what I came up with from the python script and opened a PR.
Do you want a PR for the script as well?

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Looking at the OBV build.sh… oh gee, why use so unportable things like /proc/cpuinfo? :-D

[inflex]

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Thanks for the PR. I've already pushed in some small changes too (the 3-2-1 sequence appears to be a header/lead-in as opposed to a suffix).

All scrappy at the moment but it's definitely workable now for generating the source code.

As for OBV, the build.sh is meant for linux and macOS, we don't really build on windows any more because it was making the development cycle too slow and we ran in to show-stopper incompatibilities when working with gcc as well as VS that just made everything a nightmare. Subsequently the build for windows is just done on linux with mingw64; makes everything vastly easier when it comes to cross-platform development.

As for why the /proc/cpuinfo ... not sure what it's for, probably to determine the flags for the build within CMake.

Great, let me know if you need more.

Yeah, mingw works not too bad, I recall building VLC with it (quite slow though).
I think most of build.sh can probably be done right in CMake though.

Yes, it's a classic idom to detect the number of cores to do parallel builds, except it's very Linux-specific while there's a much simpler and portable method. I fixed this in MuseScore some years ago. I already proposed a patch in my Haiku PR. :-)

Many thanks. I'll PM you in a bit after this.

Likely so - for me, it's a case of "It still works, I'm not going to break it"

I already proposed a patch in my Haiku PR. :-)

I saw that come through this morning - it'll likely be piernov who handles that as I am very much hands-off with OBV now. Put the years in to get it to a level and did the promotional work with/via Louis Rossmann, but after that is about when I forked off with FlexBV. I still push back things like file formats and bug fixes but aside from that I keep a fair distance now.

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

I made the THREAD change on my own build.sh, so at least that's one file fixed

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

I present to you... the very first image for TeboView decoder for FlexBV.

This is actually a board outline for the Lenovo X240 Yoga board.

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Interestingly, our sample file had a more complicated outline routing system. There's some segments that are prefixed with 0x08 instead of 0x0A, and with those you read only 2 int32's after the tool int32, and there's no trailing 0-value uint32.

I'll add that in to the documentation later.

I'm sure there's other little traps like that out there but we'll find them in due time.

HeLP - Need MOAR Teboview files. Gotten to the point now that I need more files of different sources so I can cross-check/differentiate various flags/bytes.

Big or small - you can email them to me if you prefer, pldaniels@gmail.com

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Found something interesting, well, two things;

1) the loose 1-byte 0-value in the header sandwiched between two other strings is actually, as it should have been expected, an empty string. One of the new files I tried broke my parser and it was because there was a 3rd string in there.

2) Some TVW files are password protected when used in the official Teboview program, but the contents are not in any way encrypted that I can tell; it's akin to stopping people from getting in to an open space by placing a doorway in their face. Very interesting.

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

There are different teboview programs. The ones which are password protected in one, are not in the other one.

Which of the files had the password? I think I can send you the right program, which doesnt ask for password.

Boardviewer doesn't let the password stop it, but the official Teboview v4 does.

Lenovo\ Legion\ Y540-15IRH\ -\ NM-C221\ REV0.1\ Boardview\ /NS-C222.tvw

It's just more amusing that it's not really doing any real protection, and in honest though, I'm *glad* it's not.

On the upside, I've already worked out a few more of the header fields because of those new files, thanks.

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Yeah, looks like these files were meant to be opened by boardviewer, not teboviewer.
