## Code guidelines
|
|
|
|
### Spacemacs core and layer
|
|
|
|
Function names follow these conventions:
|
|
- `spacemacs/xxx` is an interactive function called `xxx`
|
|
- `spacemacs//xxx` is a private function called `xxx` (implementation details)
|
|
- `spacemacs|xxx` is a _macro_ called `xxx`
|
|
|
|
Variables follow these conventions:
|
|
- `spacemacs-xxx` is a variable
|
|
- `spacemacs--xxx` is a private variable (implementation details)
|
|
|
|
### All layers
|
|
|
|
A package is initialized in a function with name `<layer>/init-xxx` where:
|
|
- `<layer>` is the layer name
|
|
- `xxx` is the package name
|
|
|
|
## Key bindings conventions
|
|
|
|
### Prefix reserved to the user
|
|
|
|
`<SPC> o` must not be used by any layer. It is reserved for the user.
|
|
|
|
### Navigation in `insert state` buffers
|
|
|
|
Navigation in buffers like `Helm` and `ido` which are in `insert state` should
|
|
be performed with <kbd>C-j</kbd> and <kdb>C-k</kbd> for vertical movements.
|
|
|
|
History navigation in shells or REPLs buffers should be bound as well to
|
|
<kbd>C-j</kbd> and <kdb>C-k</kbd>.
|
|
|
|
### Interactions with REPLs
|
|
|
|
A lot of languages can interact with a REPL. To help keeping a consistent
|
|
behavior between those languages the following conventions should be
|
|
followed:
|
|
- lower case key bindings keep the focus on the current buffer
|
|
- upper case key bindings move the focus to the REPL buffer
|
|
|
|
