In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
here doc with <<-a single space character (i.e. 0x20 ) is at the beginning of this line this line begins with a single tab character i.e 0x09 as does the next line the intended end was before this line and these were not processed by tr +++++ here doc with << a single space character (i.e. 0x20 ) is at the beginning of this line this line ...
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
Introduced in Python 2.2 as an optional feature and finalized in version 2.3, generators are Python's mechanism for lazy evaluation of a function that would otherwise return a space-prohibitive or computationally intensive list. This is an example to lazily generate the prime numbers:
PNJ – a sub-format of the MNG file format, used for encapsulating JPEG files [4] PXZ – a compressed layered image file used for the image editing website, pixlr.com; PY, PYW – Python code file; PMP – PenguinMod Project; PMS – PenguinMod Sprite; RAR – RAR Rar Archive, for multiple file archive (rar to .r01-.r99 to s01 and so on)
A final way of storing the format of a file is to explicitly store information about the format in the file system, rather than within the file itself. This approach keeps the metadata separate from both the main data and the name, but is also less portable than either filename extensions or "magic numbers", since the format has to be converted ...
In UTF-16, a BOM (U+FEFF) may be placed as the first bytes of a file or character stream to indicate the endianness (byte order) of all the 16-bit code units of the file or stream. If an attempt is made to read this stream with the wrong endianness, the bytes will be swapped, thus delivering the character U+FFFE , which is defined by Unicode as ...
A file name must start with a letter or number, a period must occur at least once each 8 characters, two consecutive periods could not appear in the name, and must end with a letter or digit. [2] By convention, the letters and numbers before the first period was the account number of the owner or the project it belonged to, but there was no ...
