Navigating the modes of Vim

This diagram illustrates navigating through Vim’s modes. It was built factoring Vim 9 (i.e., all its modes, including up to two new modes, cr and cvr, in November 2023). Information about the state() and 'showmode' is provided too.

SVG version

Some features are only available in the SVG version. It is not provided directly from within this gist’s files because SVGs do not always play nicely in GitHub (particularly, refusing to display embedded fonts).

The SVG version includes hover text help, which shows pertinent information about the underlying key, command, mode, etc.

You take a stream/buffer of binary data. The start of your data is a "Page", which has a header followed by data.

Header

You need to read the following data from the header (see https://xiph.org/ogg/doc/framing.html for more detail)

capture_pattern - bytes 0 to 3, must read OggS
stream_structure_version - byte 4, must be 0
header_type_flag - byte 5, a bitflag that tells you metadata about the page (is it a new packet? is a packet continued here? is it the first/last page of the stream?)
absolute granule position - bytes 6 to 13, not needed unless you want seeking
stream serial number - bytes 14 to 17, a serial number given to each stream contained in the Ogg file. This is important for playing Ogg files that contain other streams, such as video or cover art. You need to identify and only bother parsing the Opus stream.
