see a list of them.
**nvf** provides a list of helper commands, so that you don't have to write the
**nvf** provides a helper function, so that you don't have to write the
mapping attribute sets every time:
- `mkBinding = key: action: desc:` - makes a basic binding, with `silent` set to
true.
- `mkExprBinding = key: action: desc:` - makes an expression binding, with
`lua`, `silent`, and `expr` set to true.
- `mkLuaBinding = key: action: desc:` - makes an expression binding, with `lua`,
and `silent` set to true.
- `mkKeymap`, which mimics neovim's `vim.keymap.set` function
Do note that the Lua in these bindings is actual Lua, and not pasted into a
`:lua` command. Therefore, you should either pass in a function like
`require('someplugin').some_function`, without actually calling it, or you
should define your own functions, for example
```lua
function()
require('someplugin').some_function()
end
```
Additionally, to not have to repeat the descriptions, there's another utility
function with its own set of functions: Utility function that takes two
attribute sets:
- `{ someKey = "some_value" }`
- `{ someKey = { description = "Some Description"; }; }`
and merges them into
`{ someKey = { value = "some_value"; description = "Some Description"; }; }`
```nix
addDescriptionsToMappings = actualMappings: mappingDefinitions:
```
This function can be used in combination with the same `mkBinding` functions as
above, except they only take two arguments - `binding` and `action`, and have
different names:
- `mkSetBinding = binding: action:` - makes a basic binding, with `silent` set
to true.
- `mkSetExprBinding = binding: action:` - makes an expression binding, with
`lua`, `silent`, and `expr` set to true.
- `mkSetLuaBinding = binding: action:` - makes an expression binding, with
`lua`, and `silent` set to true.
