Util Module Introduction

The Util module provides some generally-useful routines that are more suitable for writing in Qore than in C++.

To use this module, use "%requires Util" in your code.

All the public symbols in the module are defined in the Util namespace

Functions:

• Util::check_exception_serializable()
• Util::compare_version()
• Util::flatten()
• Util::get_byte_size()
• Util::get_exception_string()
• Util::get_marketing_byte_size()
• Util::get_random_string()
• Util::glob_to_regex()
• Util::is_int()
• Util::is_float()
• Util::is_number()
• Util::lpad()
• Util::make_uri_query()
• Util::normalize_dir()
  • Util::normalize_dir_unix()
  • Util::normalize_dir_windows()
• Util::ordinal()
• Util::parse_memory_size()
• Util::parse_ranges()
• Util::parse_to_qore_value()
• Util::parse_uri_query()
• Util::plural()
• Util::regex_escape()
• Util::rpad()
• Util::same()
• Util::slice()
• Util::tmp_location()
• Util::uniq()
• Util::zip()

Release Notes

Util 1.10

• added the Util::check_exception_serializable() "check_exception_serializable()" method (issue 4708)

Util 1.8

• added get_relative_path() (issue 4488)
