In my XUL application I have to make a system call which is more complicated than running a single process, so I wrote a very simple bash file with a couple of commands and I run a process initialized with this bash file.
The problem is how to find the path of the file itself. Normally I use chrome:// or resource:// paths for all I need. But I need the absolute path in order to call this file. Is there a reliable way to get it?
I've used this function
function chromeToPath (aPath) {
if (!aPath || !(/^chrome:/.test(aPath)))
return; //not a chrome url
var rv;
var ios = Components.classes['#mozilla.org/network/io-service;1'].getService(Components.interfaces["nsIIOService"]);
var uri = ios.newURI(aPath, "UTF-8", null);
var cr = Components.classes['#mozilla.org/chrome/chrome-registry;1'].getService(Components.interfaces["nsIChromeRegistry"]);
rv = cr.convertChromeURL(uri).spec;
if (/^file:/.test(rv))
rv = this.urlToPath(rv);
else
rv = this.urlToPath("file://"+rv);
return rv;
}
function urlToPath (aPath) {
if (!aPath || !/^file:/.test(aPath))
return ;
var rv;
var ph = Components.classes["#mozilla.org/network/protocol;1?name=file"]
.createInstance(Components.interfaces.nsIFileProtocolHandler);
rv = ph.getFileFromURLSpec(aPath).path;
return rv;
}

I've searched the net all over for this but unfortunately I could not find the answer I am looking for. Do phantomjs support wildcard deletion? This is the example I found in their site.
var fs = require('fs');
var toDelete = 'someFile.txt';
fs.remove(toDelete);
phantom.exit();
But this is not what I want. I want to delete multiple files of the same type. Say for example I want to delete all the (*.png)png of this directory. Please help.
I think there is no glob-like method in PhantomJS File System module, but you can simply read contents of a directory and delete matching files.
var fs = require('fs');
var path = "/path/to/folder/to/clean/"; // needs trailing slash
var list = fs.list(path);
for(var x = 0; x < list.length; x++){
var file = path + list[x];
if(fs.isFile(file) && file.match(".png$")){
fs.remove(file);
console.log("Deleted " + file);
}
}
I am writing nginx module which construct nginx chain then write this chain buffer to nginx temporary file to use it later (just after write happen). I've been searching every page and the only solution come up is the one bellow:
// Create temp file to test
ngx_temp_file_t *tf;
tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t));
if (tf == NULL) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
tf->file.fd = NGX_INVALID_FILE;
tf->file.log = nlog;
tf->path = clcf->client_body_temp_path;
tf->pool = r->pool;
tf->log_level = r->request_body_file_log_level;
tf->persistent = r->request_body_in_persistent_file;
tf->clean = r->request_body_in_clean_file;
// if (r->request_body_file_group_access) {
// tf->access = 0660;
// }
if (ngx_create_temp_file(&tf->file, tf->path, tf->pool, tf->persistent, tf->clean, tf->access) != NGX_OK) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
if (ngx_write_chain_to_temp_file(tf, bucket->first) == NGX_ERROR) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
This code does not return NGX_ERROR, is this meant nginx successful write temporary file into client_body_temporay_path? It the answer is yes, after that, I use fopen to open file, the file is not exist?
Can anyone please give me the right solution to handle ngx_write_chain_to_temp_file?
I find myself the solution
ngx_temp_file_t *tf;
tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t));
tf->file.fd = NGX_INVALID_FILE;
tf->file.log = nlog;
tf->path = clcf->client_body_temp_path;
tf->pool = r->pool;
tf->persistent = 1;
rc = ngx_create_temp_file(&tf->file, tf->path, tf->pool, tf->persistent, tf->clean, tf->access);
//ngx_write_chain_to_file(&tf->file, bucket->first, bucket->content_length, r->pool);
ngx_write_chain_to_temp_file(tf, bucket->first);
The only thing I cannot understand is if I set tf->persistentto false (0), after the file created, I cannot read from it even if I've not passed response to output_filter yet.
activeDocument.fitArtboardToSelectedArt()
When calling this command, AI crashes on AI 5.1/6 32bit and 64bit versions. I can use the command from the menu. Has anyone encountered this? does anyone know of a work around?
The full code.
function exportFileToJPEG (dest) {
if ( app.documents.length > 0 ) {
activeDocument.selectObjectsOnActiveArtboard()
activeDocument.fitArtboardToSelectedArt()//crashes here
activeDocument.rearrangeArtboards()
var exportOptions = new ExportOptionsJPEG();
var type = ExportType.JPEG;
var fileSpec = new File(dest);
exportOptions.antiAliasing = true;
exportOptions.qualitySetting = 70;
app.activeDocument.exportFile( fileSpec, type, exportOptions );
}
}
var file_name = 'some eps file.eps'
var eps_file = File(file_name)
var fileRef = eps_file;
if (fileRef != null) {
var optRef = new OpenOptions();
optRef.updateLegacyText = true;
var docRef = open(fileRef, DocumentColorSpace.RGB, optRef);
}
exportFileToJPEG ("output_file.jpg")
I can reproduce the bug with AI CS5.
It seems that fitArtboardToSelectedArt() takes the index of an artboard as an optional parameter. When the parameter is set, Illustrator doesn't crash. (probably a bug in the code handling the situation of no parameter passed)
As a workaround you could use:
activeDocument.fitArtboardToSelectedArt(
activeDocument.artboards.getActiveArtboardIndex()
);
to pass the index of the active artboard with to the function. Hope this works for you too.
Also it's good practice to never omit the semicolon at the end of a statement.
I have a problem running the NativeProcess if I put spaces in the arguments
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
fPath = "C:\\Windows\\System32\\cmd.exe";
args.push("/c");
args.push(scriptDir.resolvePath("helloworld.bat").nativePath);
}
file = new File(fPath);
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
args.push("blah");
nativeProcessStartupInfo.arguments = args;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
in the above code, if I use
args.push("blah") everything works fine
if I use
args.push("blah blah") the program breaks as if the file wasn't found.
Seems like I'm not the only one:
http://tech.groups.yahoo.com/group/flexcoders/message/159521
As one of the users their pointed out, it really seems like an awful limitation by a cutting edge SDK of 21st century. Even Alex Harui didn't have the answer there and he's known to workaround every Adobe bug:)
Any ideas?
I am using AIR 2.6 SDK in JavaScript like this, and it is working fine even for spaces.
please check your code with this one.
var file = air.File.applicationDirectory;
file = file.resolvePath("apps");
if (air.Capabilities.os.toLowerCase().indexOf("win") > -1)
{
file = file.resolvePath(appFile);
}
var nativeProcessStartupInfo = new air.NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
var args =new air.Vector["<String>"]();
for(i=0; i<arguments.length; i++)
args.push(arguments[i]);
nativeProcessStartupInfo.arguments = args;
process = new air.NativeProcess();
process.addEventListener(air.ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(air.ProgressEvent.STANDARD_INPUT_PROGRESS, inputProgressListener);
process.start(nativeProcessStartupInfo);
To expand on this: The reason that this works (see post above):
var args =new air.Vector["<String>"]();
for(i=0; i<arguments.length; i++)
args.push(arguments[i]);
nativeProcessStartupInfo.arguments = args;
is that air expects that the arguments being passed to the nativeProcess are delimited by spaces. It chokes if you pass "C:\folder with spaces\myfile.doc" (and BTW for AIR a file path for windows needs to be "C:\\folder with spaces\\myfile.doc") you would need to do this:
args.push("C:\\folder");
args.push("with");
args.push("spaces\\myfile.doc");
Hence, something like this works:
var processArgs = new air.Vector["<String>"]();
var path = "C:\\folder with spaces\\myfile.doc"
var args = path.split(" ")
for (var i=0; i<args.length; i++) {
processArgs.push(args[i]);
};
UPDATE - SOLUTION
The string generated by the File object by either nativePath or resolvePath uses "\" for the path. Replace "\" with "/" and it works.
I'm having the same problem trying to call 7za.exe using NativeProcess. If you try to access various windows directories the whole thing fails horribly. Even trying to run command.exe and calling a batch file fails because you still have to try to pass a path with spaces through "arguments" on the NativeProcessStartupInfo object.
I've spent the better part of a day trying to get this to work and it will not work. Whatever happens to spaces in "arguments" totally destroys the path.
Example 7za.exe from command line:
7za.exe a MyZip.7z "D:\docs\My Games\Some Game Title\Maps\The Map.map"
This works fine. Now try that with Native Process in AIR. The AIR arguments sanitizer is FUBAR.
I have tried countless ways to put in arguments and it just fails. Interesting I can get it to spit out a zip file but with no content in the zip. I figure this is due to the first argument set finally working but then failing for the path argument.
For example:
processArgs[0] = 'a';
processArgs[1] = 'D:\apps\flash builder 4.5\project1\bin-debug\MyZip.7z';
processArgs[2] = 'D:\docs\My Games\Some Game Title\Maps\The Map.map';
For some reason this spits out a zip file named: bin-debugMyZip.7z But the zip is empty.
Whatever AIR is doing it is fraking up path strings. I've tried adding quotes around those paths in various ways. Nothing works.
I thought I could fall back on calling a batch file from this example:
http://technodesk.wordpress.com/2010/04/15/air-2-0-native-process-batch-file/
But it fails as well because it still requires the path to be passed through arguments.
Anyone have any luck calling 7z or dealing with full paths in the NativeProcess? All these little happy tutorials don't deal with real windows folder structure.
Solution that works for me - set path_with_space as "nativeProcessStartupInfo.workingDirectory" property. See example below:
public function openPdf(pathToPdf:String):void
}
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
var file:File = File.applicationDirectory.resolvePath("C:\\Windows\\System32\\cmd.exe");
nativeProcessStartupInfo.executable = file;
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
nativeProcessStartupInfo.workingDirectory = File.applicationDirectory.resolvePath(pathToPdf).parent;
var processArgs:Vector.<String> = new Vector.<String>();
processArgs[0] = "/k";
processArgs[1] = "start";
processArgs[2] = "test.pdf";
nativeProcessStartupInfo.arguments = processArgs;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
}
args.push( '"blah blah"' );
Command line after all supports spaces if they are nested whithin "".
So if lets say you have a file argument :
'test/folder with space/blah'
Convert it to the following
'test/"folder with space"/blah'
Optionally use a filter:
I once had a problem like this in AIR, i just simply filter the text before i push it into the array. My refrence use CASA lib though
import org.casalib.util.ArrayUtil;
http://casalib.org/
/**
* Filters a string input for 'safe handling', and returns it
**/
public function stringFilter(inString:String, addPermitArr:Array = null, permitedArr:Array = null):String {
var sourceArr:Array = inString.split(''); //Splits the string input up
var outArr:Array = new Array();
if(permitedArr == null) {
permitedArr = ("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890" as String).split('');
}
if( addPermitArr != null ) {
permitedArr = permitedArr.concat( addPermitArr );
}
for(var i:int = 0; i < sourceArr.length; i++) {
if( ArrayUtil.contains( permitedArr, sourceArr[i] ) != 0 ) { //it is allowed
outArr.push( sourceArr[i] );
}
}
return (outArr.join('') as String);
}
And just filter it via
args.push( stringFilter( 'blah blah', new Array('.') ) );
Besides, it is really bad practice to use spaces in file names / arguments, use '_' instead. This seems to be originating from linux though. (The question of spaces in file names)
This works for me on Windws7:
var Xargs:Array = String("/C#echo#a trully hacky way to do this :)#>#C:\\Users\\Benjo\\AppData\\Roaming\\com.eblagajna.eBlagajna.POS\\Local Store\\a.a").split("#");
var args:Vector.<String> = new Vector.<String>();
for (var i:int=0; i<Xargs.length; i++) {
trace("Pushing: "+Xargs[i]);
args.push(Xargs[i]);
};
NPI.arguments = args;
If your application path or parameter contains spaces, make sure to wrap it in quotes. For example path of the application has spaces C:\Program Files (x86)\Camera\Camera.exe use quotes like:
"C:\Program Files (x86)\Camera\Camera.exe"
I am trying to automate the process of scanning/cropping photos in Photoshop. I need to scan 3 photos at a time, then use Photoshop's Crop and Straighten Photos command, which creates 3 separate images. After that I'd like to save each of the newly created images as a PNG.
I looked at the JSX scripts and they seem to a lot of promise. Is what I described possible to automate in Photoshop using JavaScript or VBScript or whatever?
I just found this script just did the work for me! It automatically crop & straighten the photo and save each result to directory you specified.
http://www.tranberry.com/photoshop/photoshop_scripting/PS4GeeksOrlando/IntroScripts/cropAndStraightenBatch.jsx
Save it to local then run it in the PS=>File=>Command=>Browse
P.S I found in the comment it said the script can be executed directly by double clicking from Mac Finder or Windows Explorer.
Backup gist for the script here
I actually got the answer on the Photoshop forums over at adobe. It turns out that Photoshop CS4 is totally scriptable via JavaScript, VBScript and comes with a really kick-ass Developer IDE, that has everything you'd expect (debugger, watch window, color coding and more). I was totally impressed.
Following is an extract for reference:
you can run the following script that will create a new folder off the existing one and batch split all the files naming them existingFileName#001.png and put them in the new folder (edited)
#target Photoshop
app.bringToFront;
var inFolder = Folder.selectDialog("Please select folder to process");
if(inFolder != null){
var fileList = inFolder.getFiles(/\.(jpg|tif|psd|)$/i);
var outfolder = new Folder(decodeURI(inFolder) + "/Edited");
if (outfolder.exists == false) outfolder.create();
for(var a = 0 ;a < fileList.length; a++){
if(fileList[a] instanceof File){
var doc= open(fileList[a]);
doc.flatten();
var docname = fileList[a].name.slice(0,-4);
CropStraighten();
doc.close(SaveOptions.DONOTSAVECHANGES);
var count = 1;
while(app.documents.length){
var saveFile = new File(decodeURI(outfolder) + "/" + docname +"#"+ zeroPad(count,3) + ".png");
SavePNG(saveFile);
activeDocument.close(SaveOptions.DONOTSAVECHANGES) ;
count++;
}
}
}
};
function CropStraighten() {
function cTID(s) { return app.charIDToTypeID(s); };
function sTID(s) { return app.stringIDToTypeID(s); };
executeAction( sTID('CropPhotosAuto0001'), undefined, DialogModes.NO );
};
function SavePNG(saveFile){
pngSaveOptions = new PNGSaveOptions();
pngSaveOptions.embedColorProfile = true;
pngSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
pngSaveOptions.matte = MatteType.NONE;
pngSaveOptions.quality = 1;
pngSaveOptions.PNG8 = false; //24 bit PNG
pngSaveOptions.transparency = true;
activeDocument.saveAs(saveFile, pngSaveOptions, true, Extension.LOWERCASE);
}
function zeroPad(n, s) {
n = n.toString();
while (n.length < s) n = '0' + n;
return n;
};

Have you tried using Photoshop Actions? I don't now about the scanning part, but the rest can all be done by actions quite easily.
