zip

问题 I'm making an application in which you edit a file, and it should append the edited file to zip archive and make it downloadable. It should be cross platform (Windows and Linux). My goal is to programmatically generate the edited file and append it to static archive (which is always the same, around 3-4MBs, but around 40-50 files). I've looked at the following post on how to zip archives in node.js, however the answer by Eliseo Soto is OS dependent. I've also found daraosn/node-zip, but as I

问题 I would like to zip folder in my project from CMake . For that I use following code snippet: ADD_CUSTOM_COMMAND ( TARGET ${PROJECT_NAME} PRE_BUILD COMMAND ${CMAKE_COMMAND} ARGS -E tar cvf ${ZIP_OUT_DIR}/my_archive.zip --format=zip -- ${FOLDER_TO_ZIP}/another_folder/ ) The problem with this code is that the files after unzipping contain path component ( ../../my_file.txt in my case). I tried to use tar cvf -C ${FOLDER_TO_ZIP}/another_folder but unfortunatelly CMake doesn't accept this option.

问题 I have this scenario: I have a zip file for users to download but for each download, I want to include a 'readme' file with user specific content ( e.g. with user's name and download time ). I used archiver (zip-stream) module to zip and stream zipped content to the browser. The goal is to minimise CPU usage (i.e. zipping) and storage ( i.e. creating copy of the same zip). Here are some of the possible ways to achieve this with cons. Upon every download, make a copy of the original zip, and

问题 I’m trying to get String from txt file inside the zip file using native libcompression library.
