**menyoki** is a screencast and screenshot utility that can also perform various image related operations such as making/splitting GIFs and modifying/analyzing/viewing image files. It aims to be a lightweight command line tool for either helping out on day-to-day life operations or complicated detail-centric issues. Originally it was designed to record/screenshot terminal windows but it can be tweaked easily for other purposes with command line arguments, environment variables, or a configuration file.

## Supported Platforms

- [x] Linux
    - [x] [X11](https://www.x.org/) (fully supported)
    - [ ] [Wayland](https://wayland.freedesktop.org/) (no record/capture)
- [ ] Windows (no record/capture)
- [ ] macOS (no record/capture)

**menyoki** requires a window system [implementation](https://github.com/orhun/menyoki/blob/master/IMPLEMENTATION.md#implementing-for-other-platforms) of the supported platform for **record** and **capture** actions. Other features are expected to work normally since they don't require a window system running (or grabbing a window to operate on). For example, despite the macOS is not listed as a supported platform, **menyoki** still can perform image operations such as **edit**, **analyze** and **view** if it's compiled on macOS.

## Supported Formats

- [x] [GIF](https://en.wikipedia.org/wiki/GIF)
- [x] [APNG](https://en.wikipedia.org/wiki/APNG)
- [x] [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics)
- [x] [JPEG](https://en.wikipedia.org/wiki/JPEG)
- [x] [BMP](https://en.wikipedia.org/wiki/BMP_file_format)
- [x] [ICO](https://en.wikipedia.org/wiki/ICO_(file_format))

Command line arguments of **menyoki** are designed to be as intuitive as possible. As a result of that, an action can be performed with a chain of subcommands along with the flags and options. The general prototype for the usage of command line arguments is the following:

`menyoki (ACTION) (FORMAT) (OUTPUT)`

The subcommand that will indicate the `action` is mandatory whereas `format` and `output` subcommands might be optional (or they might not exist at all). The `format` subcommand can be one of the supported formats and `output` basically corresponds to the **save** subcommand.

The default `format` is the first listed subcommand if there is not any subcommand given for specifying a `format`. On the other hand, **save** subcommand uses the "menyoki" directory in the _home_ (or _images_ if it exists) as the default output directory.

### General <a href="https://github.com/orhun/menyoki"><img src="https://user-images.githubusercontent.com/24392180/99184076-96c10b00-2751-11eb-99ea-ad962144df76.png" height="30"></a>

Flags and options that will generally affect the execution of **menyoki** can be set before specifying the main action to perform. Then the main subcommand (action) must be specified.

`menyoki [FLAGS] [OPTIONS] <SUBCOMMAND>`

### Record <a href="https://github.com/orhun/menyoki"><img src="https://user-images.githubusercontent.com/24392180/99184076-96c10b00-2751-11eb-99ea-ad962144df76.png" height="30"></a>

**menyoki** can record an area of a window or the whole screen and encode it as a supported format. Area selection and resize is performed with the key bindings.

A few scenarios that **record** action might be helpful would be:

* Record a specific area of a window
* Record for a given duration
* Record the output of a command (especially for TUI applications)

Encoding options can be changed using the arguments of the provided format. (See the output of `menyoki record gif --help`)

### Capture <a href="https://github.com/orhun/menyoki"><img src="https://user-images.githubusercontent.com/24392180/99184076-96c10b00-2751-11eb-99ea-ad962144df76.png" height="30"></a>

**menyoki** can capture (screenshot) an area of a window or the whole screen and encode it as a supported format. Formats like **png**, **jpg**, and **pnm** have their own flags and options that might be used for changing the default encoding settings. Similar to the **record** subcommand, area selection and resize is performed with the key bindings. The same flags and options might apply for both **record** and **capture** subcommands since the actions are abstractly alike.

## Key Bindings

Key bindings are only used and present while **capture** or **record** actions are performed. Essentially key bindings are for selecting capture/record areas and resizing them without any mouse interaction.

There are 3 types of key bindings in terms of performed action:

* Action keys (main action keys such as `LAlt-S`, can be [customized](https://docs.rs/device_query/latest/device_query/keymap/enum.Keycode.html) via `--action-keys` and `--cancel-keys` options)
* Cancel keys (the keys that will cancel the operation, e.g. `LControl-D`)
* Miscellaneous keys (the keys that can be used for resizing the selected area such as `LAlt-[up]`)

| Key                               	| Action                                                      	|
|---------------------------------------|---------------------------------------------------------------|
| `LAlt-[S/Enter]`                  	| Start/stop recording or screenshot the selected area        	|
| `LControl-D, Escape`              	| Cancel the current operation                                	|
| `LControl-C`                      	| Cancel the current operation or stop recording              	|
| `LAlt-[arrow keys/hjkl]`          	| Increase the area padding (decrease the size of the area)   	|
| `LControl-LAlt-[arrow keys/hjkl]` 	| Decrease the area padding (increase the size of the area)   	|
| `LShift-LAlt-[arrow keys/hjkl]`   	| Reposition the selected area (move around)                  	|
| `LAlt-[1-9]`                      	| Set the speed factor of changing the area size (default: 3) 	|
| `LAlt-R`                          	| Reset the area padding to default                           	|

## Configuration

It's possible to override the default command line arguments with a configuration file. It can be specified via `--config` option or `$MENYOKI_CONFIG` environment variable. Also, it can be placed to a location where **menyoki** looks for as default:

* `{CONFIG_DIR}/menyoki.conf`
* `{CONFIG_DIR}/menyoki/menyoki.conf`
* `{CONFIG_DIR}/menyoki/config`

`{CONFIG_DIR}` can be one of the following depending on the platform:
* Linux: `$XDG_CONFIG_HOME` or `$HOME/.config`
  * e.g. `/home/orhun/.config`
* macOS: `$HOME/Library/Application Support`
  * e.g. `/Users/Orhun/Library/Application Support`
* Windows: `{FOLDERID_RoamingAppData}`
  * e.g. `C:\Users\Orhun\AppData\Roaming`

## Environment Variables

Corresponding environment variables can be set for overriding the command line flags and options. The general prototype of the variables that **menyoki** checks are the following:

`MENYOKI_{SECTION}_{ARGUMENT}=value`

### Examples

## Roadmap

The following are the ultimate goals of the **menyoki** project.

### Accessibility

**menyoki** should be packaged for other distributions and package managers (such as [Nixpkgs](https://github.com/NixOS/nixpkgs) and [Homebrew](https://brew.sh/)) for easy access and installation.

### Platforms

[Supported platforms](#supported-platforms) list should be extended by [implementing](https://github.com/orhun/menyoki/blob/master/IMPLEMENTATION.md#implementing-for-other-platforms) the core features of **menyoki** on different systems. (See [#2](https://github.com/orhun/menyoki/issues/2), [#4](https://github.com/orhun/menyoki/issues/4) and [#5](https://github.com/orhun/menyoki/issues/5))

### Formats

All the image formats that [image-rs](https://github.com/image-rs/image) supports for encoding should be implemented in **menyoki**. Also, the implementation of other image and video formats should be considered for encoding the frames in **record**/**capture** action. (See [supported formats](#supported-formats))

### Optimization

Encoding/decoding of some formats like GIF might be optimized for speed and efficiency. Alternative ways and options should be considered depending on the benchmarks in such cases.

### Testing

**menyoki** should be tested against different platforms and bugs must be reported for further development and support.

### Why "menyoki"?

It's a reference to the [author](https://orhun.dev)'s favorite character from the game [Patapon 2](https://en.wikipedia.org/wiki/Patapon_2).

![https://patapon.fandom.com/wiki/Menyokki?file=Moriussoo_evo.jpg](https://user-images.githubusercontent.com/24392180/99723231-f48f8300-2ac2-11eb-8118-84b873f10cce.jpg)

>[**Menyokki**](https://patapon.fandom.com/wiki/Menyokki) (aka **Tree-Pon** due to his resembling a tree) is a type of [Rarepon](https://patapon.fandom.com/wiki/Rarepon) introduced in [Patapon 2](https://patapon.fandom.com/wiki/Patapon_2). Its evolved form is **Kisuk**, and its ultimate form is **Moriussoo**. These Rarepons are green and resemble plants in various stages of development: Menyokki is a seedling, Kisuk is a sapling and Moriussoo is a full-grown tree.

The Menyokki sprite that is used as the project's logo was originally drawn by [OwocekTV](https://twitter.com/0x757775) for the fan made game [Patafour](https://patafourgame.com). He is also the creator and lead developer of Patafour and he is working on bringing the long awaited 4th installment of the Patapon franchise to life with the rest of the team.

Thanks to [owodzeg](https://github.com/owodzeg) for his hard work on [Patafour](https://patafourgame.com/) and the help with the **menyoki** logo. Kudos!
