Version 2.0.0 (2022.12.02)

This version has changed a lot of things, most of them are BREAKING CHANGEs!

• Dropped support for Python versions older than 3.7.
• Redesigned the command line interface.
  • pigar generate to generate requirements.txt.
  • pigar search to search packages/distributions by the top level module names.
  • pigar check to check the latest versions of requirements.
  • pigar -h to explore more.
  • pigar accepts a prefix for a command, such as pigar gen, pigar c.
• Refactored a lot of code and interfaces.
• Vendoring the pip to access more sophisticated utilities(pip named it's module as _internal so vendoring technology is introduced).
  • Fixed a lot of issues when parsing the requirements file, e.g. #113.
  • Fixed the issues for editable requirements, e.g. #60.
• Tweaked some default actions and introduced more options for better user experience.
  • pigar will ask user to choose the right packages/distributions if pigar has found multiple packages/distributions for the same module names. With --auto-select enabled, pigar will guess the best matched one or choose all possible packages/distributions automatically.
  • Added an option --dry-run which allows pigar to not write a requirements.txt file, just print it.
  • Added an option --follow-symbolic-links/--dont-follow-symbolic-links to let user decide whether to follow the symbolic links, fixed #89.
  • Added an option -i/--index-url to allow the custom URL of the Python Package Index, fixed #52.
  • Removed the spaces from requirements specifier, fixed #86.
  • Added an option --show-differences/--dont-show-differences to enable or disable showing the differences when the requirements file is overwritten.
• Introduced asyncio to synchronize distributions' metadata with the PyPI, the process is much faster now.
• Refactored the code to make the index database more reliable.
  • Add unique contstraints to avoid duplicate records, fixed #119.
  • Store versions in the database to do incremental index synchronization.
