### Settings
In micro, your settings are stored in `~/.config/micro/settings.json`, a file
-that is created the first time you run micro. It is a json file which holds
-all the settings and their values. To change an option, you can either
-change the value in the `settings.json` file, or you can type it in directly
-while using micro.

+value in the `settings.json` file, or you can type it in directly while using

-Simply press CtrlE to go to command mode, and type `set option value` (in the
-future, I will use `> set option value` to indicate pressing CtrlE). The
-change will take effect immediately and will also be saved to the `settings.json`
-file so that the setting will stick even after you close micro.

You can also set options locally which means that the setting will only have
-the value you give it in the buffer you set it in. For example, if you have
-two splits open, and you type `> setlocal tabsize 2`, the tabsize will only
-be 2 in the current buffer. Also micro will not save this local change to the

### Keybindings
-Keybindings work in much the same way as options. You configure them using
-the `~/.config/micro/bindings.json` file.

For example if you would like to bind `CtrlR` to redo you could put the
following in `bindings.json`:
Very simple.
You can also bind keys while in micro by using the `> bind key action` command,

-file.

### Configuration with Lua
If you need more power than the json files provide, you can use the `init.lua`
-file. Create it in `~/.config/micro`. This file is a lua file that is run
-when micro starts and is essentially a one-file plugin.

given that the current file is a Go file.
You can do that by putting the following in `init.lua`:
```lua
-function gorun()
- local buf = CurView().Buf -- The current buffer
+local config = import("micro/config")
+local shell = import("micro/shell")
+
+function init()
+ -- true means overwrite any existing binding to CtrlR
+ -- this will modify the bindings.json file
+ config.TryBindKey("CtrlR", "lua:initlua.gorun", true)
+end
+
+function gorun(bp)
+ local buf = bp.Buf
if buf:FileType() == "go" then
- HandleShellCommand("go run " .. buf.Path, true) -- true means don't run it in the background
+ -- the true means run in the foreground
+ -- the false means send output to stdout (instead of returning it)
+ shell.RunInteractiveShell("go run " .. buf.Path, true, false)
end
end

```
