A convenient wrapper for the zlib standard library that allows compression/decompression of strings with gzip.
gzip = ActiveSupport::Gzip.compress('compress me!') # => "\x1F\x8B\b\x00o\x8D\xCDO\x00\x03K\xCE\xCF-(J-.V\xC8MU\x04\x00R>n\x83\f\x00\x00\x00" ActiveSupport::Gzip.decompress(gzip) # => "compress me!"
# File activesupport/lib/active_support/gzip.rb, line 30 def self.compress(source, level = Zlib::DEFAULT_COMPRESSION, strategy = Zlib::DEFAULT_STRATEGY) output = Stream.new gz = Zlib::GzipWriter.new(output, level, strategy) gz.write(source) gz.close output.string end
Compresses a string using gzip.
# File activesupport/lib/active_support/gzip.rb, line 25 def self.decompress(source) Zlib::GzipReader.wrap(StringIO.new(source), &:read) end
Decompresses a gzipped string.
