hachoir-core 1.3.3

Hachoir项目

hachoir是一个python库，用于将二进制文件表示为 python对象。每个对象都有一个类型、值、地址等。 能够知道文件中每个位的含义。

为什么使用慢的python代码而不是快速的硬编码c代码？Hachoir有很多 有趣的功能：

• Autofix: Hachoir is able to open invalid / truncated files
• Lazy: Open a file is very fast since no information is read from file, data are read and/or computed when the user ask for it
• Types: Hachoir has many predefined field types (integer, bit, string, etc.) and supports string with charset (ISO-8859-1, UTF-8, UTF-16, …)
• Addresses and sizes are stored in bit, so flags are stored as classic fields
• Endian: You have to set endian once, and then number are converted in the right endian
• Editor: Using Hachoir representation of data, you can edit, insert, remove data and then save in a new file.

安装

对于安装，请使用setup.py或参见：http://bitbucket.org/haypo/hachoir/wiki/Install

Hachoir Core 1.3.3（2010-02-26）

• Add writelines() method to UnicodeStdout

Hachoir Core 1.3.2（2010-01-28）

• MANIFEST.in includes also the documentation

Hachoir Core 1.3.1（2010-01-21）

• Create MANIFEST.in to include ChangeLog and other files for setup.py

Hachoir Core 1.3（2010-01-20）

• Add more charsets to GenericString: CP874, WINDOWS-1250, WINDOWS-1251, WINDOWS-1254, WINDOWS-1255, WINDOWS-1256,WINDOWS-1257, WINDOWS-1258, ISO-8859-16
• Fix initLocale(): return charset even if config.unicode_stdout is False
• initLocale() leave sys.stdout and sys.stderr unchanged if the readline module is loaded: Hachoir can now be used correctly with ipython
• HachoirError: replace “message” attribute by “text” to fix Python 2.6 compatibility (message attribute is deprecated)
• StaticFieldSet: fix Python 2.6 warning, object.__new__() takes one only argument (the class).
• Fix GenericFieldSet.readMoreFields() result: don’t count the number of added fields in a loop, use the number of fields before/after the operation using len()
• GenericFieldSet.__iter__() supports iterable result for _fixFeedError() and _stopFeeding()
• New seekable field set implementation in hachoir_core.field.new_seekable_field_set

Hachoir Core 1.2.1（2008-10）

• Create configuration option “unicode_stdout” which avoid replacing stdout and stderr by objects supporting unicode string
• Create TimedeltaWin64 file type
• Support WINDOWS-1252 and WINDOWS-1253 charsets for GenericString
• guessBytesCharset() now supports ISO-8859-7 (greek)
• durationWin64() is now deprecated, use TimedeltaWin64 instead

Hachoir Core 1.2（2008-09）

• Create Field.getFieldType(): describe a field type and gives some useful informations (eg. the charset for a string)
• Create TimestampUnix64
• GenericString: only guess the charset once; if the charset attribute if not set, guess it when it’s asked by the user.

Hachoir Core 1.1（2008-04-01）

主要变化：字符串值总是编码为Unicode。详细信息：

• Create guessBytesCharset() and guessStreamCharset()
• GenericString.createValue() is now always Unicode: if charset is not specified, try to guess it. Otherwise, use default charset (ISO-8859-1)
• RawBits: add createRawDisplay() to avoid slow down on huge fields
• Fix SeekableFieldSet.current_size (use offset and not current_max_size)
• GenericString: fix UTF-16-LE string with missing nul byte
• Add __nonzero__() method to GenericTimestamp
• All stream errors now inherit from StreamError (instead of HachoirError), and create and OutputStreamError
• humanDatetime(): strip microseconds by default (add optional argument to keep them)

Hachoir Core 1.0（2007-07-10）

版本1.0.1更改日志：

• 重命名PARSer.Tabor到PARSer.PARSeryType兼容 使用未来的hachoir parser 1.0

可见更改：

• 新字段类型：timestampuuid60
• seekablefieldset：修复getitem方法并实现iter 方法，所以现在可以在hachoir wx中使用它
• 字符串值始终为Unicode，即使出现转换错误：use
• outputstream:add readbytes（）方法
• 使用ISO-639-2创建语言类
• 添加hachoir_core.profiler模块以在函数上运行探查器
• 添加hachoir_core.timeout模块以调用具有超时的函数

小改动：

• 修复许多拼写错误
• dict:使用iteritems（）而不是items（）来加快对 大型词典
