NVIM REFERENCE MANUAL

How to develop Nvim, explanation of modules and subsystems *dev-arch*
|
|
|
|
The top of each major module has (or should have) an overview in a comment at
|
|
the top of its file. The purpose of this document is to give:
|
|
|
|
1. an overview of how it all fits together
|
|
2. how-to guides for common tasks such as:
|
|
- deprecating public functions
|
|
- adding a new public (API) function
|
|
- adding a new public (UI) event
|
|
3. TODO: move src/nvim/README.md into this doc.

Data structures
|
|
|
|
Use `kvec.h` for most lists. When you absolutely need a linked list, use
|
|
`lib/queue_defs.h` which defines an "intrusive" linked list.
|
|
|
|

|
UI events
|
|
|
|
The source files most directly involved with UI events are:
|
|
1. `src/nvim/ui.*`: calls handler functions of registered UI structs (independent from msgpack-rpc)
|
|
2. `src/nvim/api/ui.*`: forwards messages over msgpack-rpc to remote UIs.
|
|
|
|
UI events are defined in `src/nvim/api/ui_events.in.h` , this file is not
|
|
compiled directly, rather it parsed by
|
|
`src/nvim/generators/gen_api_ui_events.lua` which autogenerates wrapper
|
|
functions used by the source files above. It also generates metadata
|
|
accessible as `api_info().ui_events`.
|
|
|
|
See commit d3a8e9217f39c59dd7762bd22a76b8bd03ca85ff for an example of adding
|
|
a new UI event.
|
|
|
|
UI events are deferred to UIs, which implies a deepcopy of the UI event data.
|
|
|
|
Remember to bump NVIM_API_LEVEL if it wasn't already during this development
|
|
cycle.
