Item Messages

Dir

Syntax: memlist = obj << Dir

Description: Returns the list of member files in a zip archive.

za = Open( "$TEMP\deleteMe.zip", zip );
za << Write( "ralph", "this is ralph's data" );
za << Write( "fred", "this is fred's data" );
dirlist = za << dir;
text = za << read( dirlist[1] );
dirlist[1] || ": " || text;

Read

Syntax: memdata = obj << Read( memname, <Format(blob|string)>, <Encoding(charset)> )

Description: Reads a zip archive member file into a string or blob.

za = Open( "$TEMP\deleteMe.zip", zip );
za << Write( "ralph", "this is ralph's data" );
za << Write( "fred", "this is fred's data" );
dirlist = za << dir;
text = za << read( dirlist[1] );
dirlist[1] || ": " || text;

Write

Syntax: actual name = obj << Write( memname, memdata, < "replace" > )

Description: Writes a text or blob to a zip archive member file. If the optional "replace" parameter is specified and there is an existing file with this name, the member file is replaced. Otherwise, this member name is changed to prevent overwriting an existing member; the name actually used is returned.

za << Write( "ralph", "this is ralph's data" );
za << Write( "fred", "this is fred's data" );
dirlist = za << dir;
