 # 🎀 Changelog
 
 ## Unreleased
+### Added
+- Made a few additions to the sink type:
+  - `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
+- Fix doc command not displaying correct subdocs when using shorthand api doc access (`doc api hilbish.jobs` as an example)
+- `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`.
+- Greenhouse
+  - Greenhouse is a pager library and program. Basic usage is `greenhouse <file>`
+  - Using this also brings enhancements to the `doc` command like easy
+  navigation of neighboring doc files.
+
 ### Fixed
+- Fix infinite loop when navigating history without any history. [#252](https://github.com/Rosettea/Hilbish/issues/252)
+- Return the prefix when calling `hilbish.completions.call`. [#219](https://github.com/Rosettea/Hilbish/issues/219)
 - 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)

+description: native module loading
+layout: doc
+menu:
+  docs:

+---
+
+## Introduction
+
+The hilbish.module interface provides a function to load
+Hilbish plugins/modules. Hilbish modules are Go-written
+plugins (see https://pkg.go.dev/plugin) that are used to add functionality
+to Hilbish that cannot be written in Lua for any reason.
+
+Note that you don't ever need to use the load function that is here as
+modules can be loaded with a `require` call like Lua C modules, and the
+search paths can be changed with the `paths` property here.
+
+To make a valid native module, the Go plugin has to export a Loader function
+with a signature like so: `func(*rt.Runtime) rt.Value`.
+
+`rt` in this case refers to the Runtime type at
+https://pkg.go.dev/github.com/arnodel/golua@master/runtime#Runtime
+
+Hilbish uses this package as its Lua runtime. You will need to read
+it to use it for a native plugin.
+
+Here is some code for an example plugin:
+```go
+package main
+
+import (
+	rt "github.com/arnodel/golua/runtime"
+)
+
+func Loader(rtm *rt.Runtime) rt.Value {
+	return rt.StringValue("hello world!")
+}
+```
+
+This can be compiled with `go build -buildmode=plugin plugin.go`.
+If you attempt to require and print the result (`print(require 'plugin')`), it will show "hello world!"
+
+## Interface fields
+- `paths`: A list of paths to search when loading native modules. This is in the style of Lua search paths and will be used when requiring native modules. Example: `?.so;?/?.so`
+
+## Functions
+### load(path)
+Loads a module at the designated `path`.
+It will throw if any error occurs.

+/*
+The hilbish.module interface provides a function to load
+Hilbish plugins/modules. Hilbish modules are Go-written
+plugins (see https://pkg.go.dev/plugin) that are used to add functionality
+to Hilbish that cannot be written in Lua for any reason.
+
+Note that you don't ever need to use the load function that is here as
+modules can be loaded with a `require` call like Lua C modules, and the
+search paths can be changed with the `paths` property here.
+
+To make a valid native module, the Go plugin has to export a Loader function
+with a signature like so: `func(*rt.Runtime) rt.Value`.
+
+`rt` in this case refers to the Runtime type at
+https://pkg.go.dev/github.com/arnodel/golua@master/runtime#Runtime
+
+Hilbish uses this package as its Lua runtime. You will need to read
+it to use it for a native plugin.
+
+Here is some code for an example plugin:
+```go
+package main
+
+import (
+	rt "github.com/arnodel/golua/runtime"
+)
+
+func Loader(rtm *rt.Runtime) rt.Value {
+	return rt.StringValue("hello world!")
+}
+```
+
+This can be compiled with `go build -buildmode=plugin plugin.go`.
+If you attempt to require and print the result (`print(require 'plugin')`), it will show "hello world!"

+
+Happy birthday Hilbish! As of last month, Hilbish is now 2 years old.
+Unfortunately I missed the official date, but I will still make a more
+focused post on the date (19st).
+
+I decided to fix up this website and Hilbish's logo, so that can
+be thought of as something for the 2 years milestone?
+
+# Logo
+Hilbish's old logo was.. not that good. It definitely functioned
+as a logo, but the yellow part of it looked ugly (sorry old logo).
+
+<img src="https://safe.kashima.moe/4c6e9q484pcy.png" width=256>
+<br>
+
+You would have definitely seen the new logo, since it is currently
+in use on the navigation bar and footer. Here it is in a bigger view:
+	
+<img src="https://safe.kashima.moe/oy72vpev2yi4.png" width=256>
+<br>
+	
+# Website
+Ever since this website was first made, from the release of v2.0, it has
+been doing it's job of being a website good enough, but there were a few issues.
+
+# Padding
+Padding is very important! The edges of your screen need space to do nothing,
+after all. On mobile or screens small enough, there would not be enough space
+for the auto margin to fill, and since there was no padding besides that,
+it means things would look a bit cramped. This was simple to fix.
+
+Here it is before:  
+![Before](https://safe.kashima.moe/nupzzalt2oa4.png)
+
+and after:  
+![After](https://safe.kashima.moe/r0ox4nazfi0q.png)
+
+# Docs Navigation
+On the docs page, the pages are on the left on desktop. Since
+phones are too small to have this content on the side, it stays at the top.
+This is a bit counter intuitive since it brings in extra scrolling
+when navigating to every page for docs and just doesn't look that good.
+
+A few months ago I made it collapse with the site wide navigation, but it
+was not hidden by default. So a few improvements were made:
+- Make the doc navigation hidden by default on mobile, just like site wide navigation
+- Make doc navigation have the same look as site wide navigation
+
+Here's a before:  
+![](https://safe.kashima.moe/krn0a6qwegdj.png)
+
+and after:  
+![](https://safe.kashima.moe/sk11ighz47yb.png)
+
+Looks a lot better now.
+
+# Other Changes
+If you haven't noticed, I have made other changes to the website.
+This includes:
+- Borders! Something this simple makes the website look a lot better, especially on mobile.
+- More padding and margin everywhere. Home, doc pages, blog post listing.

+
+Welcome to a fresh new release of Hilbish! Some people (or none) may be awaiting
+the long coming v2.2 release with lots of features, but I *needed* to push
+out this little bug fix (wink) release.
+
+# Bug Fixes
+## Validation checks for command input
+When running this version, you may have noticed an odd message that sometimes
+comes up when running commands. This is from the new TMOLI42SH
+(The Meaning of Life is 42 String Hash) input validation scheme.
+
+## Improved runtime code
+Commands now have a chance of taking exactly 2-3s ~~more~~ less time of running due to
+improvements in the code for shell runners!!!!!
+
+## Validate lua code
+Hilbish already threw an error when Lua code was not valid in syntax, but there was the
+need for an extra validation scheme (called OpTTCLC - Opinion based Turing Test to Check Lua Code)
+which results in less time wasted running invalid and TERRIBLE Lua code.
+
+# Features
+There is only 1 new feature in this glorious release.
+
+## Fix your mistakes for the future
+If you run a command that does not exist, Hilbish will say goodbye.
+
+# Closing
+Hope you enjoy this new release! It took a lot of effort to create this new version
+while I was busy doing completely nothing. :)))

+
+Hilbish features a simple notification system which can be
+used by other plugins and parts of the shell to notify the user
+of various actions. This is used via the `hilbish.message` interface.
+
+A `message` is defined as a table with the following properties:
+- `icon`: A unicode/emoji icon for the notification.
+- `title`: The title of the message
+- `text`: Message text/body
+- `channel`: The source of the message. This should be a
+unique and easily readable text identifier.
+- `summary`: A short summary of the notification and message.
+If this is not present and you are using this to display messages,
+you should take part of the `text` instead.
+
+The `hilbish.message` interface provides the following functions:
+- `send(message)`: Sends a message and emits the `hilbish.notification`
+signal. DO NOT emit the `hilbish.notification` signal directly, or
+the message will not be stored by the message handler.
+- `read(idx)`: Marks message at `idx` as read.
+- `delete(idx)`: Removes message at `idx`.
+- `readAll()`: Marks all messages as read.
+- `clear()`: Deletes all messages.
+
+There are a few simple use cases of this notification/messaging system.
+It could also be used as some "inter-shell" messaging system (???) but
+is intended to display to users.
+
+An example is notifying users of completed jobs/commands ran in the background.
+Any Hilbish-native command (think the upcoming Greenhouse pager) can display
+it.
