Syntax

@ZIP(COUNT, <archive>)

@ZIP(LIST, <archive>)

@ZIP(EXISTS, <archive>, <entry>)

@ZIP(ERROR)

Description

This function reads a .zip archive (see ZIP archives) without extracting it. The first parameter selects the operation:

COUNT Returns the number of entries in <archive>.
LIST Returns the entry names, joined by the current field separator.
EXISTS Returns 1 if <entry> is present in <archive>, otherwise 0.
ERROR Returns the error message from the last ZIP command or @ZIP call, or empty on success.

OK is set false if the archive cannot be read (@zip(error) aside, which always succeeds).

OK

Unchanged for error; false if the archive is missing or unreadable for the other selectors.

Example

%n = @zip(count,backup.zip)
info backup.zip contains %n entries
%i = 0
while @less(%i,%n)
  REM ... process each name from @zip(list,...) ...
  %i = @succ(%i)
wend
