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 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.

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.
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>
``` 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
SUBCOMMANDS: record Record a GIF split Split a GIF into frames make Make a GIF from frames capture Capture an image edit Edit an image analyze Analyze an image ```
| 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" |
menyoki can record an area of a window or the whole screen and encode it as a supported format (only GIF for now). Area selection and resize is performed with the key bindings.
A few scenarios that record action might be helpful would be:
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 -f, --focus Record the focused window --select Select the window to record --with-alpha Record with the alpha channel --no-borders Do not show borders for window selection --no-keys Disable the action keys while recording -h, --help Print help information
OPTIONS:
-k, --keys Set the duration for recording [default: ∞]
-c, --countdown Set the countdown before recording [default: 3]

menyoki can split a GIF 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]
``` FLAGS: -h, --help Print help information
OPTIONS:
-d, --dir

| menyoki make 1.png 2.png save 3.gif --date | Make a GIF and save the file ("3.gif") with the date information |
| menyoki make --dir frames/ | Make a GIF from the frames in the specified directory |
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.
menyoki capture [FLAGS] [OPTIONS] [COMMAND] [SUBCOMMAND]
``` FLAGS: -r, --root Capture the root window -f, --focus Capture the focused window --select Select the window to capture --with-alpha Capture with the alpha channel --no-borders Do not show borders on the focused window -h, --help Print help information

It's possible to change the GIF, PNG, JPG, and PNM encoding options with specifying flags/options to the corresponding subcommands. Also, save subcommand can be used for changing the default output settings.
``` FLAGS: --fast Encode 3 times faster (only in gifski) -h, --help Print help information
OPTIONS:
-f, --fps Cut the beginning of the GIF [default: 0.0]
--cut-end Cut the end of the GIF [default: 0.0]
SUBCOMMANDS: save Save the output file(s) ```
(Some options might be only usable with a particular action)
``` FLAGS: -h, --help Print help information
OPTIONS:
-c, --compression
SUBCOMMANDS: save Save the output file(s) ```
``` FLAGS: -h, --help Print help information
OPTIONS:
-q, --quality
SUBCOMMANDS: save Save the output file(s) ```
``` FLAGS: -h, --help Print help information
OPTIONS:
-f, --format
SUBCOMMANDS: save Save the output file(s) ```
``` FLAGS: -e, --with-extension Always save the file with an extension -t, --timestamp Add Unix timestamp to the file name -h, --help Print help information
OPTIONS:
-d, --date
ARGS:
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:
LAlt-S, can be customized via --keys option)LControl-D)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 |
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.
In Linux:
$MENYOKI_CONFIG$HOME/.config/menyoki.conf$HOME/.config/menyoki/menyoki.conf$HOME/.config/menyoki/config
Default configuration file*
```ini [general] verbose = 0 quiet = false color = 3AA431
[record] root = false focus = true select = true with-alpha = false no-borders = false no-keys = false keys = LAlt-S/Enter border = 1
duration = ∞ countdown = 3 timeout = 60 interval = 10
[split]
[make]
fps = 20 quality = 75 repeat = ∞
[capture] root = false focus = true select = true with-alpha = false no-borders = false keys = LAlt-S/Enter border = 1
countdown = 0 timeout = 60 interval = 10
[edit] convert = false grayscale = false invert = false
ratio = 1.0
blur = 0.0 hue = ±0 contrast = ±0.0 brightness = ±0 filter = lanczos3
[analyze] timestamp = false time-zone = utc
[save] with-extension = false timestamp = false date = %Y%m%dT%H%M%S
[gif] fast = false fps = 20 quality = 75 repeat = ∞ speed = 1.0 cut-beginning = 0.0 cut-end = 0.0
[png] compression = fast filter = sub
[jpg] quality = 90
[pnm] format = pixmap encoding = binary ```
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
| 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 | |
The following are the ultimate goals of the menyoki project.
menyoki should be packaged for other distributions and package managers (such as Nixpkgs and Homebrew) for easy access and installation.
Supported platforms list should be extended by implementing the core features of menyoki on different systems.
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)
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.
menyoki should be tested against different platforms and bugs must be reported for further development and support.
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 OwocekTV for his hard work on Patafour and the help with the menyoki logo. Kudos!
I only support Patreon as the funding model currently. If you like the menyoki and/or other projects on my GitHub profile, consider becoming a patron!
