hachoir 3.0a1 (2017-01-09)

Changes:

  • metadata: support TIFF picture

Big refactoring:

  • First release of the Python 3 port
  • The 7 Hachoir subprojects (core, editor, metadata, parser, regex, subfile, urwid) which lived in different directories are merged again into one big unique Python 3 module: hachoir. For example, "hachoir_parser" becomes "hachoir.parser".
  • The project moved from Bitbucket (Mercurial repository) to GitHub (Git repository). The Mercurial history since 2007 was kept.
  • Reorganize tests into a new tests/ subdirectory. Copy test files directly into the Git repository, instead of relying on an old FTP server which is not convenient. For example, it's now possible to add the required test file in a Git commit. So it's more convenient for pull requests as well.
  • Port code to Python 3: "for field in parser: yield field" becomes "yield from parser".
  • Fix PEP 8 issues: most of the code does now respect the latest PEP 8 coding style.
  • Enable Travis CI on the project: tests are on Python 3.5, check also pep8 and documentation.
  • Copy old wiki pages and documentation splitted into many subdirectories into a single consistent Sphinx documentation in the doc/ subdirectory. Publish the documentation online at http://hachoir3.readthedocs.io/
