- Fix some typos
- Remove some unnecessary text that was taking space
- Use double quotes in lua examples (this seems to be the convention in
the source code)
- Sort list of languages so they are easy to find.
- add `exposed_state` to expose 'current_node' and 'cursor_pos'
for a current buffer to the user.
- add `get_buf_state` and `get_node_api` for users.
- add documentation about api functions.
- remove `node_movement` module which should be done in user side.
features:
- node_movement is moving between scopes.
- add selection initialization from normal mode
- add a decremental selection
improvements:
- attach to buffer to run tree parsing on change
- run state update on CursorMoved
- the buffer state is:
```
{
cursor_pos = { row=row, col=col },
current_node = node_under_cursor,
selection = {
range = nil, -- activates when starting a selection
nodes = {} -- filling up when starting an incremental selection
},
parser = parser, -- parser for current buffer
}
```
- refacto all the modules reliant on parsing the tree, update the current nodes, get the current nodes...
fixes:
- fix has_parser to look for .so libraries
- fix should select the whole file when selection root in selection
