Intelhex Versions Save

• Add IntelHex.find() method to find a given byte pattern. (Scott Armitage)
• API changes: IntelHex.segments() method supports new optional parameter min_gap to allow consolidation of segments with small but existing gaps into a single segment. Default value is 1. (Ryan Downing)
• API changes: IntelHex.tofile() now supports the optional byte_count parameter from IntelHex.write_hex_file(). Only used if format = hex. (Reis Baltaoglu)
• Fix Python 3.9 compatibility issue with 'array' module (Piotr Korowacki)
• Fix installation for Python version taking setup rather from setuptools than distutils (Theo Sbrissa)

Fixes for PyPI.

What's new in IntelHex 2.2 release.

Bugfixes

• Better compatibility with Python 3. (Alexander Belchenko)
• Script hexinfo.py: Python 3 compatibility for processing start address dict keys. (patch from GitHub user mentaal)
• Unit tests: Fixed xrange overflow test for Python 2.7 on 64-bit platforms. Use sys.maxint to ensure we trigger an exception. (Masayuki Takeda)

API changes

• IntelHex.write_hex_file method: added support for new parameter: eolstyle = native | CRLF. (Alexander Belchenko)
• IntelHex.write_hex_file() method gets new optional parameter byte_count to specify how many bytes should be written to each data record in output file. Default value is 16. (patch from GitHub user erki1993)

New features

• Added get_memory_size() method: approx memory footprint of IntelHex object plus data. (Alexander Belchenko)

Major improvements in IntelHex 2.0

• The same codebase can be run on both Python 2 (2.4-2.7) and Python 3 (3.2+). No need to use 2to3.

Bugfixes

• Python 3 compatibility: tobinstr should return bytes not unicode string (Launchpad Bug #1212698).
• Python 2: better support for long int addresses (over 2GB) (Launchpad Bug #1408934)

Internals

• compat.py: provide more helper functions and aliases to reduce changes required to convert python 2 compatible sources to python 3. The code becomes quite ugly, but such compatibility has its price.

What's new in IntelHex 2.1 release.

Bugfixes

• Better Python 3 compatibility when hex2bin.py and bin2hex.py scripts are trying to read/write binary data from stdin or to stdout. (GitHub issue https://github.com/bialix/intelhex/issues/4)

New features

• API changes: added IntelHex.segments() method that returns a list of ordered tuple objects, representing contiguous occupied data addresses. (Andrew Fernandes)
• New command-line script hexinfo.py to print summary about hex files contents (file name, start address, address ranges covered by the data) in YAML format. (Andrew Fernandes)
• API changes: IntelHex.dump() method gets new optional parameters: width, withpadding to control generation of output text. (patch from GitHub user durexyl)
• Script hex2dump.py gets new option --width to support corresponding parameter in IntelHex.dump() method.

Misc

• The main activity of the IntelHex project slowly drifting towards GitHub - the main social network for OSS developers. I'd really like to get some help from additional maintainer though.
