== Warning ==

Note that 7zip issues an error when you pass something like this with the flag to preserve the directory structure:

{{{
C:\My\folder1\file.txt
C:\My\folder2\file.txt
}}}

This is a clearly a bug. However, you can easily get around this by executing the command within `C:\My` and this list of files:
{{{
folder1\file.txt
folder2\file.txt
}}}

In other words: relative paths are fine, absolute ones are not.

Since version 1.1.0 the `SevenZip` class issues in hint if this error occurs and absolute path names are used.
Line 3: Line 27:
INI files are still useful to provide settings to an application. Vista is not going to change this.
The Windows API methods provided to read a particular value have an advantage: they follow a clearly defined search path, and following that path they take not only the INI file into account, they also check the Windows registry and the command line parameter. Furthermore, they deliver always up-to-date values.
The class "SevenZip" relies on an installed version of the Open Source zipper [[http://www.7-zip.org/ | 7zip]].
Line 6: Line 29:
They have disadvantages as well: The class makes it very easy to zip as well as unzip stuff.
Line 8: Line 31:
 * They are slow
 * They return everything as a string
"SevenZip" suppports the following formats:
 * 7z
 * split
 * zip
 * gzip
 * bzip2
 * tar
Line 11: Line 39:
If you are not interested in the Windows registry and command line parameters, and if you are not changing your INI files while the application is running, then the "!IniFile" class introduced in this article might attract your attention. You can either specify an appropriate extension or set the "type" property in order to enforce a certain format.
Line 13: Line 41:
This class allows you to use a kind of APL-Syntax in your INI files.

== Details ==

An entry like:

{{{HomeFolder='C:/Windows/Appl/'}}}

results in a string holding the path, but an entry like:

{{{FormSize=300 400}}}

results in a two-element-vector "!FormSize" holding two integers.

Furthermore, an entry like:

{{{LogFolder='{"HomeFolder}Logsfiles/'}}}

is treated in a special way: the name between the curlies is taken as the name of an alreday defined value. It is then replaced by the value of that entry.

After creating an instance from the class:

{{{MyIni←⎕New #.IniClass 'C:/Appl/Example.ini'}}}

you can get all information you are interested in by calling the only method "Get". Given this file "Example.ini":
