poke is an interactive and extensible editor for structured binary data.
Its central idea is to let users describe the organisation of data rather than work exclusively with individual bytes and offsets. The accompanying Poke language provides abstractions for decoding, examining, changing and encoding structures, making the software useful for executable formats, protocols, filesystem structures and other complex binary layouts. It combines an interactive environment with facilities for building reusable descriptions and standalone binary utilities.
This is free and open source software.
Key Features
- Provides an interactive REPL for evaluating Poke expressions, definitions and statements.
- Supports structures, arrays, unions and other abstractions for describing binary layouts.
- Maps typed values onto underlying input/output spaces so changes can be written back to the data.
- Allows the same underlying data to be viewed through multiple maps and representations.
- Uses reusable modules known as pickles to package data descriptions and associated functionality.
- Includes pre-written pickles for working with several common forms of structured binary data.
- Supports dedicated packages for detailed ELF object files and DWARF debugging information.
- Provides arithmetic, functions, variables, conditionals and other procedural language facilities.
- Can execute Poke programs as standalone scripts directly from the shell.
- Lets users build specialised binary utilities on top of the Poke language and runtime.
- Provides facilities for writing custom pretty-printers, setters and getters for structured data.
- Supports configurable output styling and user startup configuration.
- Can invoke an external text editor for entering larger expressions or definitions interactively.
