**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)

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>`
#### Arguments
```
FLAGS:
-h, --help Print help information
-V, --version Print version information
-v, --verbose Increase logging verbosity
-q, --quiet Do not show output
OPTIONS:
-c, --config <FILE> Set the configuration file
--color <HEX> Set the main color [default: 3AA431]
SUBCOMMANDS:
record Record an animation
split Split an animation into frames
make Make an animation from frames
capture Capture an image
edit Edit an image
analyze Analyze an image
view View an image
```
#### Examples
| Command | Action |
|-------------------------------------------|---------------------------------------------------------------------------|
| `menyoki -V` | Print the version information |
| `menyoki -vv --color FF00FF <action>` | Set log verbosity level to 2 (trace) and use "FF00FF" as the main color |
| `menyoki -q -c menyoki.conf <action>` | Run in quiet mode and read the configuration from "menyoki.conf" |
### 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

## 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
| Command | Environment Variables |
|-------------------------------------------------------------|-----------------------------------------------------------|
| `menyoki --quiet` | `MENYOKI_GENERAL_QUIET=true` |
| `menyoki record gif --fps 10 save --timestamp` | `MENYOKI_GIF_FPS=10 MENYOKI_SAVE_TIMESTAMP=true` |
| `menyoki capture --size 200x300 jpg --quality 100` | `MENYOKI_CAPTURE_SIZE=200x300 MENYOKI_JPG_QUALITY=100` |
| `menyoki edit test.png --ratio 2.0 --filter triangle` | `MENYOKI_EDIT_RATIO=2.0 MENYOKI_EDIT_FILTER=triangle` |
| `menyoki split test.gif --dir frames/ pnm --format graymap` | `MENYOKI_SPLIT_DIR=frames/ MENYOKI_PNM_FORMAT=graymap` |
| `menyoki analyze test.png --timestamp save --date %H%M%S` | `MENYOKI_ANALYZE_TIMESTAMP=true MENYOKI_SAVE_DATE=%H%M%S` |
| `menyoki view test.png --transparent` | `MENYOKI_VIEW_TRANSPARENT=true` |
## 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).
>[**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!
