PureZIP library : ZIP / UNZIP files

Ok I will read more over it in your Docs and test it.

gnozal wrote: Probably not, because there is no ZLIB function for this. You have to unpack/repack the archive to do this.

Hmm I think its very complex because the Archive must complete
extracted in a Temporary Directory. Ok I will make some test with it
and see which solution is possible.

BTW:

I use AddFiles with wildcards because I want copy files direct in a specified
ZIP-Folder. e.g.

C:\MyFolder1_in_ZIP\MyFolder2_in_ZIP\MyFile.xyz

so I can add with AddFiles() e.g. as start with Folder2.

C:\MyFolder1_in_ZIP\*.*

so I become the required result I want.

ZIP:\MyFolder2_in_ZIP\MyFile.xyz

Therefore I requested for a optional DestPath$ params because I think
its a better way as my example on top, but it is very sad
that it is not possible to create.

I use ZLIB's zipOpenNewFileInZip() function.

zipOpenNewFileInZip() wrote:int ZEXPORT zipOpenNewFileInZip OF ((zipFile file, const char *filename, const zip_fileinfo *zipfi, const void *extrafield_local, uInt size_extrafield_local, const void *extrafield_global, uInt size_extrafield_global, const char *comment, int method, int level))

I don't see how to do what you ask : there is only the *filename, no optional DestPath$ parameter.

Ok here an other example:

In my current project I have two File-Explorers:

e.g. Left = "C:\Program Files" | Right = "ZIP:\AnyFolder"

Now I want copy (Pack) Files from left to right.

for example I want copy a folder named Test\ (available in C:\Program Files\)

Now I create a TempDir with following name...

C:\Windows\Temp\MyOwnTempDir\AnyFolder\Test\

...and copy the contains from C:\Program Files\Test\ to the TempDir on top.
Now I can add files to zip with the C:\Windows\Temp\MyOwnTempDir\*.* wildcard
withit the subfolder AnyFolder\ is also in ZIP-File. (as result so ZIP:\AnyFolder\Test\)

What I mean is a DestPath$ param for IN-ZIP-FILE (Not for HD) Sorry when
I have not correct explained.

It should work if you use #PureZIP_StorePathRelative, like this : PureZIP_AddFiles(MyZIP$, "C:\Windows\Temp\MyOwnTempDir\*.*", #PureZIP_StorePathRelative, #PureZIP_Recursive). The files will be added in the zip file in "AnyFolder\Test".

Yes. This is my current way to do. But this all is not possible without Copy to Temp before AddFiles to zip
because the Folder AnyFolder\ will not apply in ZIP:

Example:
an direct copy to ZIP with e.g. PureZIP_AddFiles(MyZIP$, "C:\Program Files\MyProg\*.*", #PureZIP_StorePathRelative, #PureZIP_Recursive)

will not apply the Folder MyProg\ in zip. With C:\Program Files\*.* it is possible but all
the other Files will also copied in zip. It is so no solution for me. Therefore my idea with an optional
path. But you mean it is not possible. ?!

That's what I explained in my previous post :

AFAIK, when adding a file to an archive, there is no optional parameter to do what you request in the ZLIB version I use.

Yes you right. Sorry! - Now I have no more questions.
I will now myself see what I can do and find some solutions.

Thanks for help.

I have a small problem:
My ZIP file contains after compressing some 0 Byte files. I don't know why.

All files are OK, if I use this:

Code: Select all

PureZIP_AddFiles(PackDatei$, SourceDir$+"*.*", #PureZIP_StorePathRelative, #PureZIP_RecursiveZeroDirs)

The ZIP contains some 0 Byte Files, if I use this:

Code: Select all

If PureZIP_Archive_Create(PackDatei$, #APPEND_STATUS_CREATE)
  PureZIP_Archive_Compress(SourceDir$+"readme.rtf", #True)
  ; .....
PureZIP_Archive_Close()

About 0 byte files and #PureZIP_RecursiveZeroDirs, have a look at this post : http://www.purebasic.fr/english/viewtop ... &start=185

You mean the packed 'readme.rtf' has 0 bytes length in archive ?

Yes. Some files have after compressing 0 Byte, other files are compressed correct.

Yes. Some files have after compressing 0 Byte, other files are compressed correct.

Could you post a link to this rtf file (or any other file wich is compressed to zero length) ?
Do you compile in ANSI or UNICODE mode ?

Thorsten1867 · Post by **Thorsten1867** » Thu Feb 01, 2007 1:58 pm

I used no unicode Exe.

Take a look to 'InstProgs' or 'Scripts'.

No problem here !
Using PB4.02 (and all beta libs) + PureZIP 1.70
Maybe you could post the code you are using ?

EDIT : Install.exe and Uninstall.exe are crashing at exit under WinNT4.

No problem with PureZIP !

There is a bug in your code. If you use a path relative to a base directory, you need to set the base directory with SetCurrentDirectory_().
So it works :

Code: Select all

Procedure Add2ZIP(Path.s, SrcPart.s, exclude.s) 
  Protected dir.l, entry.s, copy.b, exts.b 
  If Not Right(Path, 1) = "\" : Path+"\" : EndIf 
  If Not Right(SrcPart, 1) = "\" : SrcPart+"\" : EndIf 
  exts =  CountString(exclude,"|") 
  dir = ExamineDirectory(#PB_Any, Path, "") 
  If dir 
    While NextDirectoryEntry(dir) 
      entry = DirectoryEntryName(dir)  
      If entry = "." Or entry = ".." 
        Continue 
      ElseIf DirectoryEntryType(dir) = #PB_DirectoryEntry_File 
        If exclude ;{ don't write files with extension 
          copy = #True 
          For i = 1 To exts 
            If GetExtensionPart(entry) = StringField(exclude,i,"|") 
              copy = #False 
              Break 
            EndIf 
          Next 
        EndIf ;} 
        If copy 
          PureZIP_Archive_Compress(RemoveString(Path+entry, SrcPart), #True) 
          Debug "ZIP: "+RemoveString(Path+entry, SrcPart)+" ("+Str(FileSize(Path+entry))+")" 
        EndIf 
      Else 
        Add2ZIP(Path+entry+"\", SrcPart, exclude) 
      EndIf 
    Wend 
    FinishDirectory(dir) 
  EndIf 
EndProcedure
