 # 🎀 Changelog
 
 ## Unreleased
-**NOTE:** Hilbish now uses [Task] insead of Make for builds.
+### Added
-Windows support is also now at a lower tier; The only thing guaranteed is
+- Made a few additions to the sink type:
-Hilbish *compiling* on Windows.
+  - `read()` method for retrieving input (so now the `in` sink of commanders is useful)
+  - `flush()` and `autoFlush()` related to flushing outputs
+  - `pipe` property to check if a sink with input is a pipe (like stdin)
+- Add fuzzy search to history search (enable via `hilbish.opts.fuzzy = true`)
+- Show indexes on cdr list
+- `hilbish.messages` interface (details in [#219])
+- `hilbish.notification` signal when a message/notification is sent
+- `notifyJobFinish` opt to send a notification when background jobs are
+completed.
+- Allow numbered arg substitutions in aliases.
+  - Example: `hilbish.alias('hello', 'echo %1 says hello')` allows the user to run `hello hilbish`
+  which will output `hilbish says hello`.
+
+[#219]: https://github.com/Rosettea/Hilbish/issues/219
+### Fixed
+- Replaced `sed` in-place editing with `grep` and `mv` for compatibility with BSD utils
+
+## [2.1.2] - 2022-04-10
+### Removed
+- Bad april fools code ;(
+
+## [2.1.1] - 2022-04-01
+### Added
+- Validation checks for command input
+- Improved runtime performance
+- Validate Lua code
+
+## [2.1.0] - 2022-02-10
+### Added
+- Documented custom userdata types (Job and Timer Objects)
+  - Coming with this fix is also adding the return types for some functions that were missing it
+- Added a dedicated input and dedicated outputs for commanders (sinks - info at `doc api commander`).
+- Local docs is used if one of Hilbish's branches is found
+- Return 1 exit code on doc not found
+- `hilbish.runner.getCurrent()` to get the current runner
+- Initialize Hilbish Lua API before handling signals
+
+### Fixed
+- `index` or `_index` subdocs should not show up anymore
+- `hilbish.which` not working correctly with aliases
+- Commanders not being able to pipe with commands or any related operator.
+- Resolve symlinks in completions
+- Updated `runner-mode` docs
+- Fix `hilbish.completion` functions panicking when empty input is provided
+
+## [2.0.1] - 2022-12-28
+### Fixed
+- Corrected documentation for hooks, removing outdated `command.no-perm`
+- Fixed an issue where `cd` with no args would not update the old pwd
+- Tiny documentation enhancements for the `hilbish.timer` interface
+
+## [2.0.0] - 2022-12-20
+**NOTES FOR USERS/PACKAGERS UPDATING:**
+- Hilbish now uses [Task] insead of Make for builds.
+- The doc format has been changed from plain text to markdown.
+**YOU MUST reinstall Hilbish to remove the duplicate, old docs.**
+- Hilbish will by default install to **`/usr/local`** instead of just `/usr/`
+when building via Task. This is mainly to avoid conflict of distro packages
+and local installs, and is the correct place when building from git either way.
+To keep Hilbish in `/usr`, you must have `PREFIX="/usr/"` when running `task build` or `task install`
+- Windows is no longer supported. It will build and run, but **will** have problems.
+If you want to help fix the situation, start a discussion or open an issue and contribute.

+
+Hilbish is an extensible shell designed to be highly customizable.
+It is configured in Lua and provides a good range of features.
+It aims to be easy to use for anyone but powerful enough for
+those who need it.
 
 The motivation for choosing Lua was that its simpler and better to use
 than old shell script. It's fine for basic interactive shell uses,
 but that's the only place Hilbish has shell script; everything else is Lua
 and aims to be infinitely configurable. If something isn't, open an issue!

+## Introduction
+Bait is the event emitter for Hilbish. Why name it bait? Why not.
+It throws hooks that you can catch. This is what you will use if
+you want to listen in on hooks to know when certain things have
+happened, like when you've changed directory, a command has failed,
+etc. To find all available hooks thrown by Hilbish, see doc hooks.
+
+## Functions
+### catch(name, cb)
+Catches a hook with `name`. Runs the `cb` when it is thrown
+
+### catchOnce(name, cb)
+Same as catch, but only runs the `cb` once and then removes the hook
+
+### hooks(name) -> table
+Returns a table with hooks (callback functions) on the event with `name`.
+
+### release(name, catcher)
+Removes the `catcher` for the event with `name`.
+For this to work, `catcher` has to be the same function used to catch
+an event, like one saved to a variable.
+
+### throw(name, ...args)
+Throws a hook with `name` with the provided `args`

+---
+
+## Introduction
+
+Commander is a library for writing custom commands in Lua.
+In order to make it easier to write commands for Hilbish,
+not require separate scripts and to be able to use in a config,
+the Commander library exists. This is like a very simple wrapper
+that works with Hilbish for writing commands. Example:
+
+```lua
+local commander = require 'commander'
+
+commander.register('hello', function(args, sinks)
+	sinks.out:writeln 'Hello world!'
+end)
+```
+
+In this example, a command with the name of `hello` is created
+that will print `Hello world!` to output. One question you may
+have is: What is the `sinks` parameter?
+
+The `sinks` parameter is a table with 3 keys: `in`, `out`,
+and `err`. The values of these is a <a href="/Hilbish/docs/api/hilbish/#sink" style="text-decoration: none;">Sink</a>.
+
+- `in` is the standard input. You can read from this sink
+to get user input. (**This is currently unimplemented.**)
+- `out` is standard output. This is usually where text meant for
+output should go.
+- `err` is standard error. This sink is for writing errors, as the
+name would suggest.
+
+## Functions
+### deregister(name)
+Deregisters any command registered with `name`
+
+### register(name, cb)
+Register a command with `name` that runs `cb` when ran

+
+## Introduction
+The fs module provides easy and simple access to filesystem functions
+and other things, and acts an addition to the Lua standard library's
+I/O and filesystem functions.
+
+## Functions
+### abs(path) -> string
+Gives an absolute version of `path`.
+
+### basename(path) -> string
+Gives the basename of `path`. For the rules,
+see Go's filepath.Base
+
+### cd(dir)
+Changes directory to `dir`
+
+### dir(path) -> string
+Returns the directory part of `path`. For the rules, see Go's
+filepath.Dir
+
+### glob(pattern) -> matches (table)
+Glob all files and directories that match the pattern.
+For the rules, see Go's filepath.Glob
+
+### join(...) -> string
+Takes paths and joins them together with the OS's
+directory separator (forward or backward slash).
+
+### mkdir(name, recursive)
+Makes a directory called `name`. If `recursive` is true, it will create its parent directories.
+
+### readdir(dir) -> {}
+Returns a table of files in `dir`.
+

+title: Module hilbish
+description: the core Hilbish API
+layout: doc
+menu:
+  docs:
+    parent: "API"
+---
+
+## Introduction
+The Hilbish module includes the core API, containing
+interfaces and functions which directly relate to shell functionality.
+
+## Interface fields
+- `ver`: The version of Hilbish
+- `goVersion`: The version of Go that Hilbish was compiled with
+- `user`: Username of the user
+- `host`: Hostname of the machine
+- `dataDir`: Directory for Hilbish data files, including the docs and default modules
+- `interactive`: Is Hilbish in an interactive shell?
+- `login`: Is Hilbish the login shell?
+- `vimMode`: Current Vim input mode of Hilbish (will be nil if not in Vim input mode)
+- `exitCode`: xit code of the last executed command
+
+## Functions
+### alias(cmd, orig)
+Sets an alias of `cmd` to `orig`
+
+### appendPath(dir)
+Appends `dir` to $PATH
+
+### complete(scope, cb)
+Registers a completion handler for `scope`.
+A `scope` is currently only expected to be `command.<cmd>`,
+replacing <cmd> with the name of the command (for example `command.git`).
+`cb` must be a function that returns a table of "completion groups."
+Check `doc completions` for more information.
+
+### cwd() -> string
+Returns the current directory of the shell
+
+### exec(cmd)
+Replaces running hilbish with `cmd`
+
+### goro(fn)
+Puts `fn` in a goroutine
+
+### highlighter(line)
+Line highlighter handler. This is mainly for syntax highlighting, but in
+reality could set the input of the prompt to *display* anything. The
+callback is passed the current line and is expected to return a line that
+will be used as the input display.
+Note that to set a highlighter, one has to override this function.
+Example:
+```
+function hilbish.highlighter(line)
+   return line:gsub('"%w+"', function(c) return lunacolors.green(c) end)
+end
+```
+This code will highlight all double quoted strings in green.
+
+### hinter(line, pos)
+The command line hint handler. It gets called on every key insert to
+determine what text to use as an inline hint. It is passed the current
+line and cursor position. It is expected to return a string which is used
+as the text for the hint. This is by default a shim. To set hints,
+override this function with your custom handler.
+
+### inputMode(mode)
+Sets the input mode for Hilbish's line reader. Accepts either emacs or vim
+
+### interval(cb, time) -> <a href="/Hilbish/docs/api/hilbish/hilbish.timers/#timer" style="text-decoration: none;">Timer</a>
+Runs the `cb` function every `time` milliseconds.
+This creates a timer that starts immediately.
+
+### multiprompt(str)
+Changes the continued line prompt to `str`
+
+### prependPath(dir)
+Prepends `dir` to $PATH
+
+### prompt(str, typ)
+Changes the shell prompt to `str`
+There are a few verbs that can be used in the prompt text.
+These will be formatted and replaced with the appropriate values.
+`%d` - Current working directory
+`%u` - Name of current user
+`%h` - Hostname of device
+
+### read(prompt) -> input (string)
+Read input from the user, using Hilbish's line editor/input reader.
+This is a separate instance from the one Hilbish actually uses.
+Returns `input`, will be nil if ctrl + d is pressed, or an error occurs (which shouldn't happen)
+
+### run(cmd, returnOut) -> exitCode (number), stdout (string), stderr (string)
+Runs `cmd` in Hilbish's sh interpreter.
+If returnOut is true, the outputs of `cmd` will be returned as the 2nd and
+3rd values instead of being outputted to the terminal.
+
+### runnerMode(mode)
+Sets the execution/runner mode for interactive Hilbish. This determines whether
+Hilbish wll try to run input as Lua and/or sh or only do one of either.
+Accepted values for mode are hybrid (the default), hybridRev (sh first then Lua),
+sh, and lua. It also accepts a function, to which if it is passed one
+will call it to execute user input instead.
+
+### timeout(cb, time) -> <a href="/Hilbish/docs/api/hilbish/hilbish.timers/#timer" style="text-decoration: none;">Timer</a>
+Runs the `cb` function after `time` in milliseconds.
+This creates a timer that starts immediately.
+
+### which(name) -> string
+Checks if `name` is a valid command.
+Will return the path of the binary, or a basename if it's a commander.
+
+## Types
+## Sink
+A sink is a structure that has input and/or output to/from
+a desination.
+
+### Methods
+#### autoFlush(auto)
+Sets/toggles the option of automatically flushing output.
+A call with no argument will toggle the value.
+
+#### flush()
+Flush writes all buffered input to the sink.
+
+#### read() -> string
+Reads input from the sink.
+
+#### write(str)
+Writes data to a sink.
+
+#### writeln(str)
+Writes data to a sink with a newline at the end.

+
+## Functions
+### add(cmdstr, args, execPath)
+Adds a new job to the job table. Note that this does not immediately run it.
+

+
+### last() -> <a href="/Hilbish/docs/api/hilbish/hilbish.jobs/#job" style="text-decoration: none;">Job</a>
+Returns the last added job from the table.
+
+## Types
+## Job
+The Job type describes a Hilbish job.
+### Properties
+- `cmd`: The user entered command string for the job.
+- `running`: Whether the job is running or not.
+- `id`: The ID of the job in the job table
+- `pid`: The Process ID
+- `exitCode`: The last exit code of the job.
+- `stdout`: The standard output of the job. This just means the normal logs of the process.
+- `stderr`: The standard error stream of the process. This (usually) includes error messages of the job.
+
+### Methods
+#### background()
+Puts a job in the background. This acts the same as initially running a job.
+
+#### foreground()
+Puts a job in the foreground. This will cause it to run like it was
+executed normally and wait for it to complete.
+
+#### start()
+Starts running the job.

+Users can add and change the default runner for interactive input to any
+language or script of their choosing. A good example is using it to
+write command in Fennel.
+
+## Functions
+### setMode(cb)
+This is the same as the `hilbish.runnerMode` function. It takes a callback,
+which will be used to execute all interactive input.
+In normal cases, neither callbacks should be overrided by the user,
+as the higher level functions listed below this will handle it.
+
+### lua(cmd)
+Evaluates `cmd` as Lua input. This is the same as using `dofile`
+or `load`, but is appropriated for the runner interface.
+
+### sh(cmd)
+Runs a command in Hilbish's shell script interpreter.
+This is the equivalent of using `source`.

+
+## Introduction
+
+If you ever want to run a piece of code on a timed interval, or want to wait
+a few seconds, you don't have to rely on timing tricks, as Hilbish has a
+timer API to set intervals and timeouts.
+
+These are the simple functions `hilbish.interval` and `hilbish.timeout` (doc
+accessible with `doc hilbish`). But if you want slightly more control over
+them, there is the `hilbish.timers` interface. It allows you to get
+a timer via ID and control them.
+
+All functions documented with the `Timer` type refer to a Timer object.
+
+An example of usage:
+```
+local t = hilbish.timers.create(hilbish.timers.TIMEOUT, 5000, function()
+	print 'hello!'
+end)
+
+t:start()
+print(t.running) // true
+```
+
+## Interface fields
+- `INTERVAL`: Constant for an interval timer type
+- `TIMEOUT`: Constant for a timeout timer type
+
+## Functions
+### create(type, time, callback) -> <a href="/Hilbish/docs/api/hilbish/hilbish.timers/#timer" style="text-decoration: none;">Timer</a>
+Creates a timer that runs based on the specified `time` in milliseconds.
+The `type` can either be `hilbish.timers.INTERVAL` or `hilbish.timers.TIMEOUT`
+
+### get(id) -> <a href="/Hilbish/docs/api/hilbish/hilbish.timers/#timer" style="text-decoration: none;">Timer</a>
+Retrieves a timer via its ID.
+
+## Types
+## Timer
+The Job type describes a Hilbish timer.
+### Properties
+- `type`: What type of timer it is
+- `running`: If the timer is running
+- `duration`: The duration in milliseconds that the timer will run
+
+### Methods
+#### start()
+Starts a timer.
+
+#### stop()
+Stops a timer.

+Hilbish has a pretty good completion system. It has a nice looking

+
+Like most parts of Hilbish, it's made to be extensible and
+customizable. The default handler for completions in general can
+be overwritten to provide more advanced completions if needed.
+
+# Completion Handler
+By default, it provides 3 things: for the first argument,

+completion handler, it will try to run a handler for the 
+command or fallback to file completions.

+function hilbish.completion.handler(line, pos)
+	-- do things
+end
+
+It is passed 2 arguments, the entire line, and the current
+cursor position. The functions in the completion interface
+take 3 arguments: query, ctx, and fields.
+
+- The `query`, which what the user is currently trying to complete
+- `ctx`, being just the entire line
+- `fields` being a table of arguments. It's just `ctx` split up,
+delimited by spaces.
+
+It's expected to return 2 things: a table of completion groups, and
+a prefix. A completion group is defined as a table with 2 keys:
+`items` and `type`.
+
+- The `items` field is just a table of items to use for completions.
+- The `type` is for the completion menu type, being either `grid` or
+`list`.
+
+The prefix is what all the completions start with. It should be empty
+if the user doesn't have a query. If the beginning of the completion
+item does not match the prefix, it will be replaced and fixed
+properly in the line. It is case sensitive.
+
+If you want to overwrite the functionality of the general completion
+handler, or make your command completion have files as well
+(and filter them), then there is the `files` function, which is

+
+The table value that runners return can have at least 4 values:
++ input (string): The full input text.
++ exitCode (number): Exit code (usually from a command)
++ continue (boolean): Whether to prompt the user for more input
+(in the case of incomplete syntax)
++ err (string): A string that represents an error from the runner.
+This should only be set when, for example, there is a syntax error.
+It can be set to a few special values for Hilbish to throw the right
+hooks and have a better looking message.
+
++ `<command>: not-found` will throw a `command.not-found` hook
+based on what `<command>` is.
++ `<command>: not-executable` will throw a `command.not-executable` hook.
 
 The others here are defined in Lua and have EmmyLua documentation.
 These functions should be preferred over the previous ones.

-If you ever want to run a piece of code on a timed interval, or want to wait
-a few seconds, you don't have to rely on timing tricks, as Hilbish has a
-timer API to set intervals and timeouts.
-
-These are the simple functions `hilbish.interval` and `hilbish.timeout` (doc
-accessible with `doc hilbish`). But if you want slightly more control over
-them, there is the `hilbish.timers` interface. It allows you to get
-a timer via ID.
-
-# Timer Interface
-## Functions
-- `get(id)` -> timer: get a timer via its id
-- `create(type, ms, callback)` -> timer: creates a timer, adding it to the timer pool.
-`type` is the type of timer it will be. 0 is an interval, 1 is a timeout.
-`ms` is the time it will run for in seconds. callback is the function called
-when the timer is triggered.
-
-# Timer Object
-All those previously mentioned functions return a `timer` object, to which
-you can stop and start a timer again.
-
-An example of usage:
-local t = hilbish.timers.create(1, 5000, function()
-	print 'hello!'
-end)
-
-t:stop()
-print(t.running, t.duration, t.type)
-t:start()
-
-## Properties
-- `duration`: amount of time the timer runs for in milliseconds
-- `running`: whether the timer is running or not
-- `type`: the type of timer (0 is interval, 1 is timeout)
-
-## Functions
-- `stop()`: stops the timer. returns an error if it's already stopped
-- `start()`: starts the timer. returns an error if it's already started

+// library for custom commands
+/*
+Commander is a library for writing custom commands in Lua.
+In order to make it easier to write commands for Hilbish,
+not require separate scripts and to be able to use in a config,
+the Commander library exists. This is like a very simple wrapper
+that works with Hilbish for writing commands. Example:
+
+```lua
+local commander = require 'commander'
+
+commander.register('hello', function(args, sinks)
+	sinks.out:writeln 'Hello world!'
+end)
+```
+
+In this example, a command with the name of `hello` is created
+that will print `Hello world!` to output. One question you may
+have is: What is the `sinks` parameter?
+
+The `sinks` parameter is a table with 3 keys: `in`, `out`,
+and `err`. The values of these is a @Sink.
+
+- `in` is the standard input. You can read from this sink
+to get user input. (**This is currently unimplemented.**)
+- `out` is standard output. This is usually where text meant for
+output should go.
+- `err` is standard error. This sink is for writing errors, as the
+name would suggest.

+Hilbish is a extensible shell (framework). It was made to be very customizable
+via the Lua programming language. It aims to be easy to use for the casual
+people but powerful for those who want to tinker more with their shell,
+the thing used to interface with most of the system.
+
+The motivation for choosing Lua was that its simpler and better to use
+than old shell script. It's fine for basic interactive shell uses,
+but that's the only place Hilbish has shell script; everything else is Lua
+and aims to be infinitely configurable. If something isn't, open an issue!
