class Zip::Writer
Overview
Writes (streams) zip entries to an IO
.
Example
File.open("./file.zip", "w") do |file|
Zip::Writer.open(file) do |zip|
# Add a file with a String content
zip.add "foo.txt", "contents of foo"
# Add a file and write data to it through an IO
zip.add("bar.txt") do |io|
io << "contents of bar"
end
# Add a file by referencing a file in the filesystem
# (the file is automatically closed after this call)
zip.add("baz.txt", File.open("./some_file.txt"))
end
end
Defined in:
zip/writer.crConstructors
-
.new(io : IO, sync_close = false)
Creates a new writer to the given io.
-
.new(filename : String)
Creates a new writer to the given filename.
Class Method Summary
-
.open(io : IO, sync_close = false, &block)
Creates a new writer to the given io, yields it to the given block, and closes it at the end.
-
.open(filename : String, &block)
Creates a new writer to the given filename, yields it to the given block, and closes it at the end.
Instance Method Summary
-
#add(filename : String, &block)
Adds an entry that will have the given filename and current time (
Time.now
) and yields anIO
to write that entry's contents. -
#add(entry : Entry, &block)
Adds an entry and yields
IO
to write that entry's contents. -
#add(filename_or_entry : String | Entry, string : String)
Adds an entry that will have string as its contents.
-
#add(filename_or_entry : String | Entry, bytes : Bytes)
Adds an entry that will have bytes as its contents.
-
#add(filename_or_entry : String | Entry, data : IO)
Adds an entry that will have its data copied from the given data.
-
#add_dir(name)
Adds a directory entry that will have the given name.
-
#close
Closes this zip writer.
-
#closed? : Bool
Returns
true
if this writer is closed. -
#comment=(comment)
Sets the zip file comment
-
#sync_close=(sync_close)
Whether to close the enclosed
IO
when closing this writer. -
#sync_close? : Bool
Whether to close the enclosed
IO
when closing this writer.

Class Method Detail
Creates a new writer to the given io, yields it to the given block, and closes it at the end.
Creates a new writer to the given filename, yields it to the given block, and closes it at the end.
Instance Method Detail
Adds an entry that will have the given filename and current
time (Time.now
) and yields an IO
to write that entry's
contents.
Adds an entry and yields IO
to write that entry's contents.
You can choose the Entry's compression method before adding it.
- If the STORED compression method is used, its crc32, compressed
size and uncompressed size must be set and be correct with
respect to the data that will be written to the yielded
IO
. - If the DEFLATED compression method is used, crc32, compresed size and uncompressed size will be computed from the data written to the yielded IO.
You can also set the Entry's time (which is Time.now
by default)
and extra data before adding it to the zip stream.
Adds an entry that will have string as its contents.
Adds an entry that will have bytes as its contents.
Adds an entry that will have its data copied from the given data.
If the given data is a ::File
, it is automatically closed
after data is copied from it.
