CLI Parser
Noun · Development
Definitions
A library or component that interprets command-line arguments, options, defaults, and help text for a command-line interface. CLI parsers make tools easier to use by handling validation, subcommands, and usage errors consistently.
In plain English: A component that reads and interprets command-line arguments for a tool.
Example: "The internal tool adopted a CLI parser so nested subcommands and typed flags no longer required hand-rolled shell-style parsing logic."
