Ghydra

A menu-based runner for the commands you don't want to type and can't remember the key-bindings

Ghydra is a terminal-based program to run other commands through user-defined menus. Configuration is based on toml. Ideally, it should hit a sweet spot between the speed of a single key-binding and the ease-of-use of a GUI-like interface.

When Ghydra executes, an interface with a set of keybinds and their descriptions shows up. The user is then prompted to select an option or terminate the program with C-c.

Installation

Ghydra requires the go compiler currently. To install clone the repository:

go install github.com/henriqpsantos/ghydra@latest

This should add ghydra to your go env GOPATH, usually ~/go/bin/, which should be in your $PATH environment variable.

Configuration

Ghydra looks for a configuration file in $HOME/ghydra/config.toml or $XDG_CONFIG_HOME/ghydra/config.toml uses a toml based configuration with the following style:

# You can also configure the colors from the top-level menu
keyColor    = "#A0D822" # This is the color that the key within [] is shown
sepColor    = "#888888" # Color for the brackets
descColor   = "#A0AAEE" # Color for the description text
headerColor = "#A0AAEE"

[[menu]] # This is a top-level menu
desc = "The menu's description"
key = "k"

[[menu.action]]
desc = "This action is inside the 'k' menu"
key = "r"
command = "echo hello"

[[menu.action]]
desc = "This action is also inside the 'k' menu"
key = "w"
command = "echo world" 

[[menu.menu]] # You can define menus within menus
desc = "This is a menu within a menu"
key = "m"

[[menu]] # Another top-level menu
desc = "This menu is on the root level"
key = "l"

As a tree, the menu will look something like this:

root menu
 ├── k    > The menu's description 
 │   ├─ r > This action is inside the 'k' menu
 │   ├─ w > This action is also inside the 'k' menu
 │   └─ m > This is a menu within a menu
 │      ├ ...
 │     ...
 │
 └── l    > This menu is on the root level

Shell support

Ghydra will output the interface to stderr and output the result of whichever command is selected to stdout. To run the command output by Ghydra in fish:

eval (ghydra)

To setup a keybind to execute Ghydra and run the selected program (in this case by pressing <C-x>):

bind \cx 'eval (ghydra)'
