Controlling paths within a Zip

See more Zip Examples

How to control the paths stored within a .zip. Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let zip = chilkat::Zip::new();

// This is the directory structure on the local filesystem
// from which we'll create .zip archives:
// The root directory is /temp/filesToZip
// 
// We have these files:
// /temp/filesToZip/faxCover.doc
// /temp/filesToZip/exe/Setup.exe
// /temp/filesToZip/images/cheese.jpg
// /temp/filesToZip/images/dude.gif
// /temp/filesToZip/images/img3.gif
// /temp/filesToZip/images/img4.gif
// /temp/filesToZip/images/img5.gif
// /temp/filesToZip/images/scream.jpg
// /temp/filesToZip/images/imageInfo/scream.xml
// /temp/filesToZip/images/imageInfo/cheese.xml
// /temp/filesToZip/text/html/bonaireFishing.html
// /temp/filesToZip/text/html/upload.html
// /temp/filesToZip/text/txt/hello.txt
// /temp/filesToZip/text/txt/HelloWorld123.txt
// /temp/filesToZip/text/xml/hamlet.xml
// /temp/filesToZip/text/xml/pigs.xml

// There are three properties to help control the paths stored
// within a .zip:
// AppendFromDir
// PathPrefix
// DiscardPaths
// 

// First we'll demonstrate AppendFromDir
// When a directory tree is appended via AppendFiles or
// AppendFilesEx, the AppendFromDir sets the base of the 
// directory tree appended (if the file pattern contains a 
// relative path, or no path at all).

// Clear the zip object.
let _ = zip.new_zip("test1.zip");

let recurse = true;

zip.set_append_from_dir("/temp/filesToZip");
let _ = zip.append_files("*.xml", recurse).is_ok();

// The zip will contain:
// images/imageInfo/scream.xml
// images/imageInfo/cheese.xml
// text/xml/hamlet.xml
// text/xml/pigs.xml

if zip.write_zip_and_close().is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// Clear the zip object.
let _ = zip.new_zip("test2.zip").is_ok();

zip.set_append_from_dir("/temp/filesToZip/images");
let _ = zip.append_files("*.xml", recurse).is_ok();
zip.set_append_from_dir("/temp/filesToZip/text");
let _ = zip.append_files("*.xml", recurse).is_ok();

// The zip will contain:
// imageInfo/scream.xml
// imageInfo/cheese.xml
// xml/hamlet.xml
// xml/pigs.xml

if zip.write_zip_and_close().is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// The PathPrefix property adds an arbitrary path prefix to each
// file in the .zip.
// For example:

// Clear the zip object.
let _ = zip.new_zip("test3.zip").is_ok();

zip.set_path_prefix("chilkat/");

zip.set_append_from_dir("/temp/filesToZip/images");
let _ = zip.append_files("*.xml", recurse).is_ok();
zip.set_append_from_dir("/temp/filesToZip/text");
let _ = zip.append_files("*.xml", recurse).is_ok();

// The zip will contain:
// chilkat/imageInfo/scream.xml
// chilkat/imageInfo/cheese.xml
// chilkat/xml/hamlet.xml
// chilkat/xml/pigs.xml

if zip.write_zip_and_close().is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// The DiscardPaths property removes the path from each file
// in the zip:
// For example:

// Clear the zip object.
let _ = zip.new_zip("test4.zip").is_ok();

zip.set_path_prefix("");
zip.set_discard_paths(true);

zip.set_append_from_dir("/temp/filesToZip/");
let _ = zip.append_files("*", recurse).is_ok();

// The zip will contain:
// faxCover.doc
// Setup.exe
// cheese.jpg
// dude.gif
// img3.gif
// img4.gif
// img5.gif
// scream.jpg
// scream.xml
// cheese.xml
// bonaireFishing.html
// upload.html
// hello.txt
// HelloWorld123.txt
// hamlet.xml
// pigs.xml

if zip.write_zip_and_close().is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// You can combine PathPrefix with DiscardPaths:

// Clear the zip object.
let _ = zip.new_zip("test5.zip").is_ok();

zip.set_path_prefix("chilkat/");
zip.set_discard_paths(true);

zip.set_append_from_dir("/temp/filesToZip/");
let _ = zip.append_files("*", recurse).is_ok();

// The zip will contain:
// chilkat/faxCover.doc
// chilkat/Setup.exe
// chilkat/cheese.jpg
// chilkat/dude.gif
// chilkat/img3.gif
// chilkat/img4.gif
// chilkat/img5.gif
// chilkat/scream.jpg
// chilkat/scream.xml
// chilkat/cheese.xml
// chilkat/bonaireFishing.html
// chilkat/upload.html
// chilkat/hello.txt
// chilkat/HelloWorld123.txt
// chilkat/hamlet.xml
// chilkat/pigs.xml

if zip.write_zip_and_close().is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// One last example -- combine DiscardPaths with PathPrefix
// with multiple calls to AppendFiles:

// Clear the zip object.
let _ = zip.new_zip("test6.zip").is_ok();

zip.set_discard_paths(true);
zip.set_append_from_dir("/temp/filesToZip/");

// Get all .gif files:
zip.set_path_prefix("gif/");
let _ = zip.append_files("*.gif", recurse).is_ok();

// Get all .jpg files:
zip.set_path_prefix("jpg/");
let _ = zip.append_files("*.jpg", recurse).is_ok();

// Get all .xml files:
zip.set_path_prefix("xml/");
let _ = zip.append_files("*.xml", recurse).is_ok();

// The zip will contain:
// jpg/cheese.jpg
// gif/dude.gif
// gif/img3.gif
// gif/img4.gif
// gif/img5.gif
// jpg/scream.jpg
// xml/scream.xml
// xml/cheese.xml
