bool atranslator:save ()

Returns

This function returns true if the contents of the archive could successfully be saved back into its source file, false otherwise.

This snippet writes a .zip archive and saves it in the end. It handles common errors that could happen during archive management. 

-- Get a generic translator to the resource instance directory.
local resRoot = fileCreateTranslator( "/" );

-- Open or create some .zip archive.
local zipFile = false;
local zipTranslator = false;

if ( resRoot:exists( "archive.zip" ) ) then
    zipFile = resRoot:open( "archive.zip", "rb+" );

    if ( zipFile ) then
        zipTranslator = fileOpenArchive( zipFile );
    end
else
    zipFile = resRoot:open( "archive.zip", "wb+" );

    if ( zipFile ) then
        zipTranslator = fileCreateZIP( zipFile );
    end
end

-- Check that everything was created alright.
if not ( zipFile ) then
    outputDebugString( "could not open or create the archive stream" );
    return false;
end

if not ( zipTranslator ) then
    outputDebugString( "could not create the .zip translator based on the stream file" );

    -- Clean up the file handle.
    zipFile:destroy();
    return false;
end

-- Write a random file.
local randFile = zipTranslator:open( tostring( math.random( 0, 1 ) ) .. ".rnd", "wb" );

randFile.write(
[[This is a randomly generated file.
Its name is random. ]] .. math.random( 0, 100 )
);

-- Clean up the file handle.
-- We do not actually have to do this, because all files are closed from a translator when it is destroyed.
randFile:destroy();

-- Save the archive and clean up the handles.
zipTranslator:save();
zipTranslator:destroy();
zipFile:destroy();
