cdecl-dump: Visual Command-Line Tool for Understanding Complex C Declarations
By
bluetomcat
A weekday bagel. Dependable, satisfying, no fuss.
Summary
cdecl-dump is a command-line tool that visually dumps and explains complex C declarations by breaking them down into understandable stages. The tool helps programmers understand C declarations by showing how each part of the declaration works, starting with the bare identifier and then adding operators like pointers, functions, and arrays in a visual format. It includes documentation on building, usage, and understanding the visual dumps.
Key quotes
· 4 pulledDump C declarations visually on the command line.
Each printed stage mirrors the eventual use of the declared variable – it is a sample sub-expression of the intended use.
We always start with the bare identifier because it is the lowermost expression one can use.
Pointers and functions are represented by a single box, arrays are represented by multiple boxes which are optionally truncated for counts larger than 8.
