+# Config file format
+
+Cove's config file uses the [TOML](https://toml.io/) format.
+
+Here is an example config that changes a few different options:
+
+```toml
+measure_widths = true
+rooms_sort_order = "importance"
+
+[euph.servers."euphoria.leet.nu".rooms]
+welcome.autojoin = true
+test.username = "badingle"
+test.force_username = true
+private.password = "foobar"
+
+[keys]
+general.abort = ["esc", "ctrl+c"]
+general.exit = "ctrl+q"
+tree.action.fold_tree = "f"
+```
+
+## Key bindings
+
+Key bindings are specified as strings or lists of strings. Each string specifies
+a main key and zero or more modifier keys. The modifier keys (if any) are listed
+first, followed by the main key. They are separated by the `+` character and
+**no** whitespace.
+
+Examples of key bindings:
+- `"ctrl+c"`
+- `"X"` (not `"shift+x"`)
+- `"space"` or `" "` (both space bar)
+- `["g", "home"]`
+- `["K", "ctrl+up"]`
+- `["f1", "?"]`
+- `"ctrl+alt+f3"`
+- `["enter", "any+enter"]` (matches `enter` regardless of modifiers)
+
+Available main keys:
+- Any single character that can be typed
+- `esc`, `enter`, `space`, `tab`, `backtab`
+- `backspace`, `delete`, `insert`
+- `left`, `right`, `up`, `down`
+- `home`, `end`, `pageup`, `pagedown`
+- `f1`, `f2`, ...
+
+Available modifiers:
+- `shift` (must not be used with single characters)
+- `ctrl`
+- `alt`
+- `any` (matches as long as at least one modifier is pressed)

+**Type:** key binding
+**Default:** `["L", "ctrl+right"]`
+
+Move to newer unseen message.
+
+### `keys.tree.cursor.to_older_message`
+
+**Required:** yes
+**Type:** key binding
+**Default:** `["h", "left"]`
+
+Move to older message.
+
+### `keys.tree.cursor.to_older_unseen_message`
+
+**Required:** yes
+**Type:** key binding
+**Default:** `["H", "ctrl+left"]`
+
+Move to older unseen message.
+
+### `keys.tree.cursor.to_parent`
+
+**Required:** yes
+**Type:** key binding
+**Default:** `"p"`
+
+Move to parent.
+
+### `keys.tree.cursor.to_root`
+
+**Required:** yes
+**Type:** key binding
+**Default:** `"P"`
+
+Move to root.
+
+### `measure_widths`
+
+**Required:** yes
+**Type:** boolean
+**Default:** `false`
+
+Whether to measure the width of graphemes (i.e. characters) as displayed
+by the terminal emulator instead of estimating the width.
+
+Enabling this makes rendering a bit slower but more accurate. The screen
+might also flash when encountering new graphemes.
+
+See also the `--measure-widths` command line option.
+
+### `offline`
+
+**Required:** yes
+**Type:** boolean
+**Default:** `false`
+
+Whether to start in offline mode.
+
+In offline mode, cove won't automatically join rooms marked via the
+`autojoin` option on startup. You can still join those rooms manually by
+pressing `a` in the rooms list.
+
+See also the `--offline` command line option.
+
+### `rooms_sort_order`
+
+**Required:** yes
+**Type:** string
+**Values:** `"alphabet"`, `"importance"`
+**Default:** `"alphabet"`
+
+Initial sort order of rooms list.
+
+`"alphabet"` sorts rooms in alphabetic order.
+
+`"importance"` sorts rooms by the following criteria (in descending
+order of priority):
+
+1. connected rooms before unconnected rooms
+2. rooms with unread messages before rooms without
+3. alphabetic order
+
+### `time_zone`
+
+**Required:** no
+**Type:** string
+**Default:** `$TZ` or local system time zone
+
+Time zone that chat timestamps should be displayed in.
+
+This option can either be the string `"localtime"`, a [POSIX TZ string],
+or a [tz identifier] from the [tz database].
+
+When not set or when set to `"localtime"`, cove attempts to use your
+system's configured time zone, falling back to UTC.
+
+When the string begins with a colon or doesn't match the a POSIX TZ
+string format, it is interpreted as a tz identifier and looked up in
+your system's tz database (or a bundled tz database on Windows).
+
+If the `TZ` environment variable exists, it overrides this option.
+
+[POSIX TZ string]: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08_03
+[tz identifier]: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
+[tz database]: https://en.wikipedia.org/wiki/Tz_database
+
+### `width_estimation_method`
+
+**Required:** yes
+**Type:** string
+**Values:** `"legacy"`, `"unicode"`
+**Default:** `"legacy"`
+
+How to estimate the width of graphemes (i.e. characters) as displayed by
+the terminal emulator.
+
+`"legacy"`: Use a legacy method that should mostly work on most terminal
+emulators. This method will never be correct in all cases since every
+terminal emulator handles grapheme widths slightly differently. However,
+those cases are usually rare (unless you view a lot of emoji).
+
+`"unicode"`: Use the unicode standard in a best-effort manner to
+determine grapheme widths. Some terminals (e.g. ghostty) can make use of
+this.
+
+This method is used when `measure_widths` is set to `false`.
+
+See also the `--width-estimation-method` command line option.

+Cove is a TUI client for [euphoria.leet.nu](https://euphoria.leet.nu/), a threaded
real-time chat platform.
-It runs on Linux, Windows and macOS.
+It runs on Linux, Windows, and macOS.
-## Manual installation
+## Installing cove
-This section contains instructions on how to install cove by compiling it yourself.
-It doesn't assume you know how to program, but it does assume basic familiarity with the command line on your platform of choice.
-Cove runs in the terminal, after all.
+Download a binary of your choice from the
+[latest release on GitHub](https://github.com/Garmelon/cove/releases/latest).
-### Installing rustup
-
-Cove is written in Rust, so the first step is to install rustup. Either install
-it from your package manager of choice (if you have one) or use the
-[installer](https://rustup.rs/).
-
-Test your installation by running `rustup --version` and `cargo --version`. If
-rustup is installed correctly, both of these should show a version number.
-
-Cove is designed on the current version of the stable toolchain. If cove doesn't
-compile, you can try switching to the stable toolchain and updating it using the
-following commands:
-```bash
-$ rustup default stable
-$ rustup update
-```
-
-### Installing cove
-
-To install or update to the latest release of cove, run the following command:
-
-```bash
-$ cargo install --force --git https://github.com/Garmelon/cove --branch latest
-```
-
-If you like to live dangerously and want to install or update to the latest,
-bleeding-edge, possibly-broken commit from the repo's main branch, run the
-following command.
-
-**Warning:** This could corrupt your vault. Make sure to make a backup before
-running the command.
-
-```bash
-$ cargo install --force --git https://github.com/Garmelon/cove
-```
-
-To install a specific version of cove, run the following command and substitute
-in the full version you want to install:
-
-```bash
-$ cargo install --force --git https://github.com/Garmelon/cove --tag v0.1.0
-```
-
-### Using cove
+## Using cove
To start cove, simply run `cove` in your terminal. For more info about the
available subcommands such as exporting room logs or resetting cookies, run
@@ -66,3 +22,12 @@ If you delete rooms, cove's vault (the database it stores messages and other
things in) won't automatically shrink. If it takes up too much space, try
running `cove gc` and waiting for it to finish. This isn't done automatically
because it can take quite a while.
+
+## Configuring cove
+
+A complete list of config options is available in the [CONFIG.md](CONFIG.md)
+file or via `cove help-config`.
+
+When launched, cove prints the location it is loading its config file from. To
+configure cove, create a config file at that location. This location can be
+changed via the `--config` command line option.

+
+Cove's config file uses the [TOML](https://toml.io/) format.
+
+Here is an example config that changes a few different options:
+
+```toml
+measure_widths = true
+rooms_sort_order = "importance"
+
+[euph.servers."euphoria.leet.nu".rooms]

+general.exit = "ctrl+q"
+tree.action.fold_tree = "f"
+```
+
+## Key bindings
+
+Key bindings are specified as strings or lists of strings. Each string specifies
+a main key and zero or more modifier keys. The modifier keys (if any) are listed
+first, followed by the main key. They are separated by the `+` character and
+**no** whitespace.
+
+Examples of key bindings:
+- `"ctrl+c"`
+- `"X"` (not `"shift+x"`)
+- `"space"` or `" "` (both space bar)
+- `["g", "home"]`
+- `["K", "ctrl+up"]`
+- `["f1", "?"]`
+- `"ctrl+alt+f3"`
+- `["enter", "any+enter"]` (matches `enter` regardless of modifiers)
+
+Available main keys:
+- Any single character that can be typed
+- `esc`, `enter`, `space`, `tab`, `backtab`
+- `backspace`, `delete`, `insert`
+- `left`, `right`, `up`, `down`
+- `home`, `end`, `pageup`, `pagedown`
+- `f1`, `f2`, ...
+
+Available modifiers:
+- `shift` (must not be used with single characters)
+- `ctrl`
+- `alt`
+- `any` (matches as long as at least one modifier is pressed)
