I am trying to unzip the file: [https://wwwinfo.mfcr.cz/ares/ares_vreo_all.tar.gz][1] into google drive folder.
So, I have downloaded the file using google script, but can not properly unzip it. Could you, please, help me with it?
Thank you in advance!
Update:
Here is my code
function updateDB() {
var url = 'https://wwwinfo.mfcr.cz/ares/ares_vreo_all.tar.gz';
var blob = UrlFetchApp.fetch(url).getBlob();
var folder = DriveApp.getFolderById('fileid');
var archive = folder.createFile(blob);
unzip(archive);
}
function unzip(archive){
var zipblob = archive.getBlob();
var uncompressed1 = Utilities.ungzip(zipblob);
}
So I receive the following error:
Exception: Could not decompress gzip.
I guess it does not decompress normally, that is why I am asking if you would know different way

You can use the Utilities Class to unzip your File.
To unzip the gzip you have to call the ungzip() method:
var textBlob = Utilities.newBlob("Some text to compress using gzip compression");
// Create the compressed blob.
var gzipBlob = Utilities.gzip(textBlob, "text.gz");
// Uncompress the data.
var uncompressedBlob = Utilities.ungzip(gzipBlob);
That's the example provided in the official documentation.
You can also take a look at the answer given to this question that also explains how to use the Utilities Class in combination with Google Drive.

I'm creating a plugin I would like to be used for both Mac and Windows.
As the file trees are different, I would like to find a simpler way to source a file in a function contained in my /host/index.jsx file.
My file is located at /files/thisismyfile.psd
Currently I can only successfully source it by entering the full file tree from the main hard drive:
var fileRef = new File("/Library/Application Support/Adobe/CEP/extensions/com.my.panel/files/thisismyfile.psd");
I would much prefer to use something like:
var fileRef = new File("./files/thisismyfile.psd");
I've also tried testing having the file in each other folder and simply searching for:
var fileRef = new File("thisismyfile.psd");
With no luck! Any ideas?
Failing that, is it possible to code it so that it says:
"If this is mac, then search for the file here. If this is windows, then search for the file here."?
I ended up using this script to determine the location of the file depending on whether the system being used is mac or windows.
function isMacOS() {
return ($.os.toLowerCase().indexOf('mac') >= 0);
}
var fileRef = isMacOS()
? new File("/Library/Application Support/Adobe/CEP/extensions/my.panel/files/filename.psd")
: new File("C:\Program Files\Common Files\Adobe\CEP\extensions\my.panel\files\filename.psd");
var docRef = app.open(fileRef);
};
Using JSZip, is there a way to edit a file within a zipped file?
I've tried looking for solutions and going through the API but I can't seem to find a solution.
Any help with this would be great! Thanks in advance!
You can edit a file inside your zip with .file method.
zip.file("existing_filename", "new file content");
This method is used for adding and updating file content.
Just make sure the file already exist.
You can read more about it in the documentation.
You can refer to the official documentation.
And here's a more complete Node.js example:
var fs = require("fs");
var JSZip = require("jszip");
async function zipDemo() {
// read the existing zip file
var zipData = fs.readFileSync("input.zip");
var zip = await JSZip.loadAsync(zipData);
// add a new JSON file to the zip
zip.file("sample.json", JSON.stringify({demo:123}));
// write out the updated zip
zip.generateNodeStream({type:'nodebuffer', streamFiles:true})
.pipe(fs.createWriteStream('output.zip'))
.on('finish', function () {
console.log("output`enter code here`.zip written.");
});
}
zipDemo();
I have application store and applications have their url. I want to download apks from those urls to my jaggery server. Although below code(my first solution) create myApp.apk successfully, its not work properly.
First i tried to below code,
var url = "http://img.xxx.com/006/someApp.apk";
var data = get(url, {});
var file = new File("myApp.apk");
file.open("w");
file.write(data.data);
file.close();
when i print data.data value, its look like
i also tried,
var file = new File("http://img.xxx.com/006/someApp.apk");
file.saveAs("myApp.txt");
Can anyone help me?
.apk files are Android application files, and they are expected to start with PK, because they are actually zip archives!
They're not meant to be unzipped, although you can do it to see some of the application resources (but there are better ways for reverse engineering .apk files such as Apktool, if that's what you're looking for).
According to jaggery documentations, file.write is writing the String representation of the object to the file. So that's why you are getting an apk file which cannot be installed.
However you can make it work using copyURLToFile in apache commons-io java library as follows since jaggery supports java itself and all of WSO2 products have apache commons-io library in their class path.
<%
var JFileUtils = Packages.org.apache.commons.io.FileUtils;
var JUrl = Packages.java.net.URL;
var JFile = Packages.java.io.File;
var url = new JUrl("http://img.xxx.com/006/someApp.apk");
JFileUtils.copyURLToFile(url, new JFile("myApp.apk"));
print("done");

Your file will be stored on $CARBON_HOME directory by default, unless you specified relative or absolute path to the file.
I'm used to selecting, opening and reading a text file (CSV, JSON) from my local directory. I now have access to our data feeds online but don't know how to do the same thing with a URL instead of a local file.
For a local file I simply use something like this:
var myFile = File.openDialog();
myFile.open();
myFile.read();
Is there a way to do this with a feed from a URL in javascript for AE?
Here is one of the feeds: feeds.nfl.com/feeds-rs/schedules.json
No need to save file, just one line do the trick =)
data = JSON.parse(system.callSystem('curl -s "https://path_to_json"'));
I think in After Effects the easiest way is to do a system call.
The Socket object from ExtendScript is complicated. Look at GetURLs.jsx by Rorohiko.
You need to allow your script to access the network. See this stackoverflow
# Mac Osx
var curlcmd = "curl feeds.nfl.com/feeds-rs/schedules.json > ~/Desktop/test/schedules.json";
var stdout = system.callSystem(curlcmd);
$.writeln(stdout);
var file = File("~/Desktop/test/schedules.json");
file.open();
var content = file.read();
file.close();
$.writeln(content);
According to the lesson 15 I pass .dcm file to the volume. I get no errors (e.g. no parsing errors I faced before) but nothing is displayed. What could be wrong with the .dcm files?
Here is a excerpt of the code I use:
function demo(file){
var _dicom = [file];
var r = new X.renderer3D();
r.init();
var v = new X.volume();
v.file = _dicom.map(function(v) {
return file;
});
r.add(v);
r.render();
r.onShowtime = function() {
v.volumeRendering = true;
};
};
I pass the full file path here. Well, I'm not sure it's a correct wording, but I'd lile to know, what dicom settings or parameters could cause such a behaviour, no errors and no diplayed data. Thanks in advance.
Did you try to drag the .dcm file into http://slicedrop.com and see the same effect? DICOM support currently only exists for uncompressed DICOM files and we didn't get Ultrasound too work yet. So on uncompressed MR data or CT data in DICOM it should work.
