ArgumentParser Export API

The ArgumentParser provides introspection methods to enumerate and inspect all registered argument definitions at runtime.

Methods

getAllArgs

pub fn getAllArgs(self: *const ArgumentParser) []const ArgSpec

Returns a read-only slice of every registered ArgSpec. The returned pointers remain valid until the parser is deinitialised or the argument list is mutated.

getAllSubcommands

pub fn getAllSubcommands(self: *const ArgumentParser) []const SubcommandSpec

Returns a read-only slice of every registered SubcommandSpec.

getAllGroups

pub fn getAllGroups(self: *const ArgumentParser) []const ArgumentGroup

Returns a read-only slice of every registered ArgumentGroup.

getAllMutualExclusions

pub fn getAllMutualExclusions(self: *const ArgumentParser) []const []const []const u8

Returns the mutual-exclusion groups (each group is a slice of arg names).

exportSpec

pub fn exportSpec(self: *ArgumentParser) CommandSpec

Builds and returns the full CommandSpec snapshot.

getArgSpec

pub fn getArgSpec(self: *const ArgumentParser, name: []const u8) ?ArgSpec

Looks up a single ArgSpec by name, long flag, destination, or alias. Returns null if no match.

totalArgCount

pub fn totalArgCount(self: *const ArgumentParser) usize

Returns the number of registered arguments (including hidden ones).

totalSubcommandCount

pub fn totalSubcommandCount(self: *const ArgumentParser) usize

Returns the number of registered subcommands.

totalGroupCount

pub fn totalGroupCount(self: *const ArgumentParser) usize

Returns the number of registered argument groups.

buildSpec

pub fn buildSpec(self: *ArgumentParser) CommandSpec

Builds the internal CommandSpec snapshot. exportSpec is a convenience alias for this.
