This file must be converted with binhex 4.0 ai

As you can see, data fork is not extracted automatically and you can use MimeBinHex instance to access both data and resource forks and other information stored inside the BinHex encoded attachment. Tags: Attachments , BinHex , Email component.

Can't find what you're looking for? Basically, it works in a similar fashion to stdio's fread :. These are maintained in the object, so parsing two different input streams simultaneously is possible.

Files on the Macintosh consist of two parts, called forks : Data fork The actual data included in the file. The BinHex format squashes that data into transmittable ASCII as follows: The file is output as a byte stream consisting of some basic header information filename, type, creator , then the data fork, then the resource fork.

Expr Input a HEX stream from any open able expression. NoComment If true, the parser should not attempt to skip a leading " This file Skip past the opening comment in the file, which is of the form: This file must be converted with BinHex 4.

Read in the BinHex file header. You must do this first! The leading comment is output, using the requires attribute. Note that done always converts and hands you whatever is left. Someday, the converter may also allow you give it an object that responds to read , or a FileHandle, and it will do all the nasty buffer-filling on its own, serving you stuff line by line: Someday, maybe Feel free to voice your opinions.

How to get them For this reason, a BinHex parser has to be somewhat stateful: you cannot have code like this: NO! Since we have to be stateful anyway, we use the parser object to keep our state.

We need to be handle large input files Solutions that demand reading everything into core don't cut it in my book. Boy, is this slow!

How it works Since BinHex is a layered format, consisting of A Macintosh file [the "BIN"] Encoded as a structured 8-bit bytestream, then Compressed to reduce duplicate bytes, then First, to allow transferring binary files therefore coded on 8 bits sent on the Internet, whose pipes are not always "8-bit clean". This means that there must be some sort of mapping between a 8-bit stream and a 7-bit stream. Secondly, to bundle in a single container both forks composing a Macintosh file.

Last but not the least, the author, Yves Lempereur, added a compression function, of the RLE type, to avoid sending repetitive sequences of identical characters.

The suffix used for binhexed files is generally HQX. Please note that this comment line is not mandatory, according to the specs, but that all utilities we already used put this line at the beginning of the file. The BinHex standard also specifies that the first and last character of the data stream should be a colon :. Most classical binhexed files only have this first comment line, followed by a carriage return and a line feed and only one pair of those.

However, we already saw files where this line was not the first one, but the second one. Our programs were amended to also handle correctly such files. The BinHex standard is one of the working modes with Mime of most Macintosh mail softwares.

Those packages code and decode the data stream automatically, and most users never know they are using binhexed files.
