Detailed Description

Structure to help class command_test parse it's parameters.

Constructor & Destructor Documentation

◆ test_parser()

bs::test_parser::test_parser ( const std::span< const std::string > & vTokens )

inlineexplicitnoexcept

Contstructs a test_parser

Parameters

vTokens Tokens to parse

Member Function Documentation

◆ do_toplevel()

bool bs::test_parser::do_toplevel ( std::size_t & nPos )

Evaluate a full expression (top-level entry point).

Parameters

nPos	Token positon

Returns: Operation result

◆ increase_depth()

void bs::test_parser::increase_depth ( )

inline

Increases the current recursion/evaluation depth. Ensures that the depth does not exceed MAX_DEPTH.

Exceptions

math_error If increasing the depth would exceed MAX_DEPTH.
