`dijo` (>= v0.2.3), can be configured via a configuration
file. After its first run, `dijo` creates a configuration
file. `dijo` must be restarted for changes in the
configuration file to take effect.

This file is saved in different directories based on your
operating system:

 - GNU/Linux: `$XDG_CONFIG_HOME/dijo/config.toml`
 - MacOS: `$HOME/Library/Application Support/rs.nerdypepper.dijo/config.toml`
 - Win10: `{FOLDERID_RoamingAppData}\nerdypepper\dijo\config\config.toml`

The default config file (created on first run) looks
something like this, `config.toml`:

```
[look]
true_chr = "·"
false_chr = "·"
future_chr = "·"

[colors]
reached = "cyan"
todo = "magenta"
inactive = "light black"
```

### Look

Variables in this section define the characters `dijo` uses
in `DAY` mode to represent days of the month. Every value in
this section must span exactly 1 character in length.

- `true_chr`: The character to use in a Bit habit when the
  goal is **reached**

- `false_chr`: The character to use in a Bit habit when the
  goal is **not reached**

-  `future_chr`: The character to use in a Bit habit when
   the day is **untracked**.


### Colors

Variables in this section define the colors `dijo` uses in
all modes:

 - `reached`: The color to use when the goal is **reached**
   for the day. This is also the color used in `WEEK` mode
   to fill the progress bar.

 - `todo`: The color to use when the goal is **yet to be
   reached**.

 - `inactive`: The color to use for **unfocused habits and
   untracked days**.

The values in this section are strings, and may be populated
by one of the following:

```
 black               light black
 red                 light red
 green               light green
 yellow              light yellow
 blue                light blue
 magenta             light magenta
 cyan                light cyan
 white               light white

 default  -- uses your terminal's background color
 #123456  -- any color in hex (supported only on true color terminals)
```

**Note**: These values have to be quoted (ex.: `reached =
"black"`)
