ValueError

[kismetllj]

Hiiiiiiii,I wonder why the following error appears after I copy your code and run it:
ValueError: The least populated class in y has only 1 member, which is too few. The minimum number of groups for any class cannot be less than 2.

Thank you for making this list as I don't understand the internals of Automa. I think it is fine to keep the Buffer type and .data, .markpos, .marginpos, and .bufferpos fields as they are very well documented in src/buffer.jl

Also, do you know if Automa is using the unread or unsafe_unread functions? I would like to better specify how those functions interact with position and mark.

Lastly, does Automa use any of the write functions?

Automa does not use unread or unsafe_unread. It does use Base.write, but not writing to a TranscodingStream, so it shouldn't be of concern for this package.

From what I can tell, what Automa uses is:

• That you can get a Buffer containing the input data by doing stream.state.buffer1 - this could be changed to a getbuffer function if necessary
• The fields .markpos, .marginpos and .bufferpos, and their precise meaning
• That you can get a Vector{UInt8} by reading the .data field of a Buffer - this could perhaps be changed to a function also, since maybe in the future, this should be a Memory
• That a TranscodingStream behaves like an ordinary IO object, e.g. that eof works and returns a Bool. This is perhaps too trivial to mention.
