See ZipFile Class on MSDN. It shows the required framework version is 4.5. Once the framework version is fixed check you have added a reference to the System.IO.Compression.FileSystem.dll assembly and added a using System.IO.Compression directive to your class.
Maybe Groovy doesn’t have ‘native’ support for zip files, but it is still pretty trivial to work with them. I’m working with zip files and the following is some of the logic I’m using: def zipFile = new java.util.zip.ZipFile(new File(‘some.zip’)) zipFile.entries().each { println zipFile.getInputStream(it).text } You can add additional logic using a findAll method: def … Read more
What you can do is pipe the file in normally, then rename it in the zip echo ‘foo bar’ | zip > file.zip printf “@ -\n@=filename.txt\n” | zipnote -w file.zip
The .zip file specification states: 4.4.17.1 The name of the file, with optional relative path. The path stored MUST not contain a drive or device letter, or a leading slash. All slashes MUST be forward slashes “https://stackoverflow.com/” as opposed to backwards slashes ‘\’ for compatibility with Amiga and UNIX file systems etc. If input came … Read more
I ran into this issue as well. However my fix was much easier. My file names and paths were too long to be zipped. There was no warning. I resolved it by copy-pasting the directory to another with a shorter path. e.g. from /this/path/is/way/too/ooo/ooo/oo/long to /home/Desktop
EDIT: See note in comments – SharpZipLib is now unmaintained, and you probably want to avoid it. Open source: #ZipLib I believe that the classes in the System.IO.Compression namespace are fine for compressing/decompressing a single stream of data, but there’s nothing built into the framework to cope with actual zip files. EDIT: As noted in … Read more
Use itertools.cycle to cycle around to the beginning of L2: from itertools import cycle dict(zip(L1, cycle(L2))) # {‘A’: ‘1’, ‘B’: ‘2’, ‘C’: ‘3’, ‘D’: ‘1’, ‘E’: ‘2’} In your case, concatenating L2 with itself also works. # dict(zip(L1, L2 * 2)) dict(zip(L1, L2 + L2)) # {‘A’: ‘1’, ‘B’: ‘2’, ‘C’: ‘3’, ‘D’: ‘1’, ‘E’: … Read more
You can read about it here: http://research.swtch.com/2010/03/zip-files-all-way-down.html Here you will find r.zip, which contains itself.
According to Wikipedia http://en.wikipedia.org/wiki/Zip_(file_format) seems that zip files have headers for File last modification time and File last modification date so any zip file checked into git will appear to git to have changed if the zip is rebuilt from the same content since. And it seems that there is no flag to tell it … Read more
This page has a list of “magic” file signatures. Grab the ones you need and put them in a dict like below. Then we need a function that matches the dict keys with the start of the file. I’ve written a suggestion, though it can be optimized by preprocessing the magic_dict into e.g. one giant … Read more
