compression

问题 I'm looking into different ways to minify my JavaScript code including the regular JSMin, Packer, and YUI solutions. I'm really interested in the new Google Closure Compiler, as it looks exceptionally powerful. I noticed that Dean Edwards packer has a feature to exclude lines of code that start with three semicolons. This is handy to exclude debug code. For instance: ;;; console.log("Starting process"); I'm spending some time cleaning up my codebase and would like to add hints like this to

问题 Is there anyway in .Net (C#) to extract data from a zip file without decompressing the complete file? Simply I possibly want to extract data (file) from the start of a zip file, obviously this depends if the compression algorithm compress the file in a deterministic order. 回答1: DotNetZip is your friend here. As easy as: using (ZipFile zip = ZipFile.Read(ExistingZipFile)) { ZipEntry e = zip["MyReport.doc"]; e.Extract(OutputStream); } (you can also extract to a file or other destinations).

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . Let's say I have a very large integer, around the order of 10**200. Now storing the integer in a file will take some amount of space. If I convert it into an iterator using yield , can I store the iterator in a

问题 I have to do a RLE algorithm in java with the escape character (Q) Example 1 if i have an input like: 77777 => 57 BBBBBBBBB => 10B FBFB8923 => 004FBFB8923 2365553422 => 005236555342200 this is the code that i made: public String coderRLE(string text) { String res = new String(); char[] charArray = text.toCharArray(); char caractere = 0; int num = 0; int i = 0; for (char c : charArray) { if (c != caractere && i != 0) { if (num >= 2) { res += num; res += caractere; } else { res += caractere; }

问题 I am trying to compress file with Java ByteArrayOutputstream,but I failed.If I change the ouputstream to FileOutput stream,it can work.What should I do to make it work?and why? Here is my code(Sorrry,my english is so poor): import java.io.ByteArrayOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.nio.charset.Charset; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; import org.apache

问题 Someone knows a java library to decode/encode SDCH compression??? it has been created by Google and implemented in their Google Chrome web browser... so it will be a standard soon Some links about it: http://en.wikipedia.org/wiki/Shared_Dictionary_Compression_Over_HTTP http://google-opensource.blogspot.ie/2008/09/open-vcdiff-encoder-and-decoder-for-rfc.html Thanks! 回答1: SDCH is the name of the standard which applies the VCDIFF compression algorithm to HTTP. The web page lists implementations.

问题 Is there any function in vala like zip:list_dir in erlang ? I found libgsf, but I don't want to decompress the zip file. 回答1: You can use libarchive . void check_ok (Archive.Result r) throws IOError { if (r == Archive.Result.OK) return; if (r == Archive.Result.WARN) return; throw new IOError.FAILED ("libarchive returned an error"); } int main () { try { var a = new Archive.Read (); check_ok (a.support_filter_all ()); check_ok (a.support_format_all ()); check_ok (a.open_filename ("archive.zip"
