Screen{shot,cast} and perform ImageOps on the command line 🌱 🏞️

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

• Linux
  • X11 (fully supported)
  • Wayland (no record/capture)
• Windows (no record/capture)
• macOS (no record/capture)

menyoki requires a window system implementation 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

• GIF
• APNG
• PNG
• JPEG
• BMP
• ICO
• TIFF
• PNM
• TGA
• farbfeld

Usage

Action
Result

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

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

Record

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)

menyoki record [FLAGS] [OPTIONS] [COMMAND] [SUBCOMMAND]

FLAGS:
    -r, --root          Record the root window

menyoki record --root --size $(slop)

Split

menyoki can split an animation into frames (extract images) if the split subcommand is provided and it can save frames as one of the supported formats with the use of trailing format subcommand.

menyoki split [OPTIONS] <FILE> [SUBCOMMAND]

Arguments

FLAGS:
    -h, --help    Print help information

Examples

Capture

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 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])

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:

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 and Homebrew) for easy access and installation.

Platforms

Supported platforms list should be extended by implementing the core features of menyoki on different systems. (See #2, #4 and #5)

Formats

All the image formats that image-rs 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)

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's favorite character from the game Patapon 2.

Menyokki (aka Tree-Pon due to his resembling a tree) is a type of Rarepon introduced in 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 for the fan made game Patafour. 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 for his hard work on Patafour and the help with the menyoki logo. Kudos!
