Flatbuffers: Emacs mode for flatbuffers featuring syntax highlighting

[jdees]

Searching the internet I did not see any Emacs mode for flatbuffers which is often an indicator for the maturity of a library/language.

Is someone aware of an Emacs mode for flatbuffers, in particular to have syntax highlighting for "*.fbs" files?
If not, would it make sense to create one (happy to help)?

I've not heard of one, no. Maybe everyone is using https://marketplace.visualstudio.com/items?itemName=gaborv.flatbuffers instead? ;)
There's also https://plugins.jetbrains.com/plugin/8582-flatbuffers-support
Feel free to make one for emacs.. where would this normally be distributed?

sure Visual Studio Code is popular - but it's not the only editor :)

• simplest way: add single file ".el" in flatbuffers repository (this is e.g. done by protobuf, see https://github.com/protocolbuffers/protobuf/blob/master/editors/protobuf-mode.el)
• more elegant/official way: add to emacs package manager https://melpa.org

I will consider building a simple emacs mode for it (need to schedule some time for it)...

I also request a flatbuffer syntax file for Emacs.
Could you update it? Thanks

Hello @Asalle
When opening the file https://github.com/tensorflow/tensorflow/blob/master/tensorflow/lite/schema/schema.fbs#L384

Some fields are shown in bule while others are not recognized. Is it the purpose?
Please see the following screenshot:

Nope, that's a bug. Will take a look today!

@haifenghan hey, I looked into that these 3 days and it's not very easy to fix. I'll need to write a regex for enums and learn some more elisp. I'll let you know if I'll come up with any solution. Pls report any other issues in "Issues" page of the flatbuffers-mode so we'll not spamming this thread.

[haifenghan]

Many thanks

@haifenghan check out this. It's not perfect, but I guess much better now. I figured it out, so it'll be complete soon. If you have any bugs, please open an issue in the flatbuffers-mode project. Thanks for the feedback!
