About
This is a conversion of TurboPower Software's Abbrevia library for the Free Pascal Compiler. Abbrevia is a compression toolkit that supports PKZIP 4, Microsoft CAB, TAR, & gzip formats. The package contains visual components that simplify the manipulation of ZIP files.
Status: Alpha, ie it needs testing.
This package was created and generously made available to the open source community by TurboPower Software.
License: MPL 1.1.
Download
The latest release of FpArchive can be found on the Lazarus CCR Files page.
Outdated: Getting the latest source from CVS. Only svn ("Subversion") is being used by now. CVS is no longer being used.
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/lazarus-ccr login
(press the Enter key when prompted for a password)
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/lazarus-ccr co fparchive
This package is also available from the Free Pascal Compiler CVS in projects/contrib/abbrevia
Dependencies
Small amounts of 386 assembler.
Usage
1. For your project open "Project->Compiler Options->Other unit files" and add the path to the FPArchive units
2. In the "uses" clause of your unit add AbBase, AbBrowse, AbZBrows, AbUnzper, AbArcTyp
3. Create an unzip object:
UnZip := TAbUnZipper.Create(nil);
4. Set the directory where you want to extract the files to:
UnZip.BaseDirectory := '/path/to/extract';
5. To restore directories structure (optional) add this line:
UnZip.ExtractOptions := [eoCreateDirs, eoRestorePath];
6. Try to extract all CSV files (for example) from an archive file:
try
UnZip.FileName := '/file/to/extract.zip';
UnZip.ExtractFiles('*.csv');
except
on E: Exception do
begin
//some error handling
end;
end;
7. Free the created object:
UnZip.Free;
