I am working on After Effects scripts and using AE scripting guide as a base of learning.
I have one After Effect project which includes two AE projects in it and each of the project having multiple items in it.
I want to fetch the composition from the master project having specific name but without looping through all items in the project. For example,
var myComp = app.project.comp("Composition Name");
Is this possible ? Is there any other way around ?
You can get the comp in this way:
var myComp;
for (var i = 1; i <= app.project.numItems; i ++) {
if ((app.project.item(i) instanceof CompItem) && (app.project.item(i).name === 'Comp Name')) {
myComp = app.project.item(i);
break;
}
}
Be aware that if you want to check if there's no more comp with the same name you should write it like this:
var myComp;
for (var i = 1; i <= app.project.numItems; i ++) {
if ((app.project.item(i) instanceof CompItem) && (app.project.item(i).name === 'Comp Name')) {
if (myComp) {
throw new Error();//or something else
}
myComp = app.project.item(i);
}
}
And if you want you can put it in array and check if it's the only return myComp[0] and if not do womething like throw error

I Would like to create a script for photoshop who allow me to search some files with a specific name (for example : 300x250_F1.jpg, 300x250_F2.jpg, 300x600_F1.jpg, etc... ) in differents subfolders (all in the same parent folder) and after load them in my active document. The problem is names of subfolders will be everytime differents.
I definitely need some help :)
i found a code which almost do what i want (thank you).
I'm almost good but i have a problem: if the variable "mask" have only one value, it works. But with few values, it doesn't work anymore.
I think it's because i made an array with the mask variable and i have to update the script...
var topFolder = Folder.selectDialog("");
//var topFolder = new Folder('~/Desktop/PS_TEST');
var fileandfolderAr = scanSubFolders(topFolder, /\.(jpg)$/i);
//var fileandfolderAr = scanSubFolders(topFolder, /\.(jpg|tif|psd|bmp|gif|png|)$/i);
var fileList = fileandfolderAr[0];
var nom = decodeURI(fileList);
//all file paths found and amount of files found
//alert("fileList: " + nom + "\n\nFile Amount: " + fileList.length);
//alert(allFiles);
for (var a = 0; a < fileList.length; a++) {
var docRef = open(fileList[a]);
//do things here
}
function scanSubFolders(tFolder, mask) { // folder object, RegExp or string
var sFolders = [];
var allFiles = [];
var mask = ["300x250_F1", "300x250_F2"];
sFolders[0] = tFolder;
for (var j = 0; j < sFolders.length; j++) { // loop through folders
var procFiles = sFolders[j].getFiles();
for (var i = 0; i < procFiles.length; i++) { // loop through this folder contents
if (procFiles[i] instanceof File) {
if (mask == undefined) {
allFiles.push(procFiles); // if no search mask collect all files
}
if (procFiles[i].fullName.search(mask) != -1) {
allFiles.push(procFiles[i]); // otherwise only those that match mask
}
}
else if (procFiles[i] instanceof Folder) {
sFolders.push(procFiles[i]); // store the subfolder
scanSubFolders(procFiles[i], mask); // search the subfolder
}
}
}
return [allFiles, sFolders];
}
There are several ways you can accomplish this without reassigning mask within the scanSubFolders function.
Solution 1: use a regex
The function is already set up to accept a regex or string as a mask. You just need to use one that would match the pattern of the files you're targeting.
var fileandfolderAr = scanSubFolders(topFolder, /300x250_F(1|2)/gi);
Solution 2: call the function within a loop
If regex isn't your thing, you could still utilize an array of strings, but do it outside the function. Loop the array of masks and call the function with each one, then execute your primary logic on the results of each call.
var topFolder = Folder.selectDialog("");
var myMasks = ["300x250_F1", "300x250_F2"];
for (var index in myMasks) {
var mask = myMasks[index]
var fileandfolderAr = scanSubFolders(topFolder, mask);
var fileList = fileandfolderAr[0];
for (var a = 0; a < fileList.length; a++) {
var docRef = open(fileList[a]);
//do things here
}
}
Don't forget to remove var mask = ["300x250_F1", "300x250_F2"]; from within the scanSubFolders function or else these won't work.
I'm working on a script that should go through a photoshop document and relink all visible linked objects to a new specified file. I've gotten the loop working so that it cycles through every layer and collects only the visible layers, but for the life of me I can't find if there's a method available to relink a smart object. The closest I've found is this script:
https://gist.github.com/laryn/0a1f6bf0dab5b713395a835f9bfa805c
but when it gets to desc3.putPath(idnull, new File(newFile));, it spits out an error indicating that the functionality may not be present in the current Photoshop version. The script itself is 4 years old so it may be out of date.
Any help would be appreciated!
MY script as it stands is below:
// SELECT FILE //
var files = File.openDialog("Please select new linked file");
var selectedFile = files[0];
// GET ALL LAYERS //
var doc = app.activeDocument;
var allLayers = [];
var allLayers = collectAllLayers(doc, allLayers);
function collectAllLayers (doc, allLayers)
{
for (var m = 0; m < doc.layers.length; m++)
{
var theLayer = doc.layers[m];
if (theLayer.typename === "ArtLayer")
{
allLayers.push(theLayer);
}
else
{
collectAllLayers(theLayer, allLayers);
}
}
return allLayers;
}
// GET VISIBLE LAYERS //
var visibleLayers = [];
for (i = 0; i < allLayers.length; i++)
{
var layer = allLayers[i];
if (layer.visible && layer.kind == LayerKind.SMARTOBJECT)
{
visibleLayers.push(layer);
}
}
// REPLACE LAYERS
for (i = 0; i < visibleLayers.length; i++)
{
var layer = visibleLayers[i];
//--> REPLACE THE FILE HERE
}
Note: I am aware that this script currently may be error-prone if you don't know exactly how it works; I'm not intending to publish it at this time so I'm not super concerned with that at the moment. Mostly I just need the core functionality to work.
I used an AM function for getting visible smart objects — it works much faster. But if you want you can use yours. The important bit is relinkSO(path);: it'll also work in your script (just don't forget to select a layer: activeDocument.activeLayer = visibleLayers[i];)
Note that it works similar to Photoshop Relink to File command — if used on one instance of Smart Object all the instances are going to be relinked. If you want to relink only specific layers you'll have to break instancing first (probably using the New Smart Object via Copy command)
function main() {
var myFile = Folder.myDocuments.openDlg('Load file', undefined, false);
if (myFile == null) return false;
// gets IDs of all smart objects
var lyrs = getLyrs();
for (var i = 0; i < lyrs.length; i++) {
// for each SO id...
// select it
selectById(lyrs[i]);
// relink SO to file
relinkSO(myFile);
// embed linked if you want
embedLinked()
}
function getLyrs() {
var ids = [];
var layers, desc, vis, type, id;
try
{
activeDocument.backgroundLayer;
layers = 0;
}
catch (e)
{
layers = 1;
}
while (true)
{
ref = new ActionReference();
ref.putIndex(charIDToTypeID('Lyr '), layers);
try
{
desc = executeActionGet(ref);
}
catch (err)
{
break;
}
vis = desc.getBoolean(charIDToTypeID("Vsbl"));
type = desc.getInteger(stringIDToTypeID("layerKind"));
id = desc.getInteger(stringIDToTypeID("layerID"));
if (type == 5 && vis) ids.push(id);
layers++;
}
return ids;
} // end of getLyrs()
function selectById(id) {
var desc = new ActionDescriptor();
var ref = new ActionReference();
ref.putIdentifier(charIDToTypeID('Lyr '), id);
desc.putReference(charIDToTypeID('null'), ref);
executeAction(charIDToTypeID('slct'), desc, DialogModes.NO);
} // end of selectById()
function relinkSO(path) {
var desc = new ActionDescriptor();
desc.putPath( charIDToTypeID('null'), new File( path ) );
executeAction( stringIDToTypeID('placedLayerRelinkToFile'), desc, DialogModes.NO );
} // end of relinkSO()
function embedLinked() {
executeAction( stringIDToTypeID('placedLayerConvertToEmbedded'), undefined, DialogModes.NO );
} // end of embedLinked()
}

can someone show me how to query an array of strings with realm in react-native?
assume i have an array like the following:
const preferences = ["automatic","suv","blue",eco]
What I want is to get realm results where ALL strings in the attribute "specifications" of Cars is in "preferences".
E.g.: If an instance of Cars.specifications contains ["automatic","suv"]
a result should be returned.
But if an instance of Cars.specifications contained ["automatic,"suv","green"] this instance shouldn't be returned.
The length of preferences can vary.
Thank you very much.
Update:
What i tried is the following:
const query = realm.objects("Cars").filtered('specifications = preferences[0] OR specifications = preferences[1]')
As you see it is an OR operator which is surely wrong and it is hardcoded. Looping with realm really confuses me.
This code will work!
const collection = realm.objects('Cars');
const preferences = ["automatic","suv","blue","eco"];
let queryString = 'ANY ';
for (let i = 0; i < preferences.length; i++) {
if (i === 0) {
queryString += `specifications CONTAINS '${preferences[i]}'`;
}
if (i !== 0 && i + 1 <= preferences.length) {
queryString += ` OR specifications CONTAINS '${preferences[i]}'`;
}
}
const matchedResult = collection.filtered(queryString);

this simple code works fine and allows to add a BeginSample/EndSample call around each Update/LateUpdate/FixedUpdate function. However it doesn't take in consideration early return instructions, for example as result of a condition. Do you know how to write a similar function that take in considerations early returns so that the EndSample call will be executed under every circumstance?
Note that I am not a Cecil expert, I am just learning now. It appears to me that Cecil automatically updates the operations that returns early after calling InsertBefore and similar functions. So if a BR opcode was previously jumping to a specific instruction address, the address will be updated after the insertions in order to jump to the original instruction. This is OK in most of the cases, but in my case it means that an if statement would skip the last inserted operation as the BR operation would still point directly to the final Ret instruction. Note that Update, LateUpdate and FixedUpdate are all void functions.
foreach (var method in type.Methods)
{
if ((method.Name == "Update" || method.Name == "LateUpdate" || method.Name == "FixedUpdate") &&
method.HasParameters == false)
{
var beginMethod =
module.ImportReference(typeof (Profiler).GetMethod("BeginSample",
new[] {typeof (string)}));
var endMethod =
module.ImportReference(typeof (Profiler).GetMethod("EndSample",
BindingFlags.Static |
BindingFlags.Public));
Debug.Log(method.Name + " method found in class: " + type.Name);
var ilProcessor = method.Body.GetILProcessor();
var first = method.Body.Instructions[0];
ilProcessor.InsertBefore(first,
Instruction.Create(OpCodes.Ldstr,
type.FullName + "." + method.Name));
ilProcessor.InsertBefore(first, Instruction.Create(OpCodes.Call, beginMethod));
var lastRet = method.Body.Instructions[method.Body.Instructions.Count - 1];
ilProcessor.InsertBefore(lastRet, Instruction.Create(OpCodes.Call, endMethod));
changed = true;
}
}
as a Bonus, if you can explain to me the difference between Emit and Append a newly created instruction with the same operand. does Append execute an Emit under the hood or does something more?
I may have found the solution, at least apparently it works. I followed the code used to solve a similar problem from here:
https://groups.google.com/forum/#!msg/mono-cecil/nE6JBjvEFCQ/MqV6tgDCB4AJ
I adapted it for my purposes and it seemed to work, although I may find out other issues. This is the complete code:
static bool ProcessAssembly(AssemblyDefinition assembly)
{
var changed = false;
var moduleG = assembly.MainModule;
var attributeConstructor =
moduleG.ImportReference(
typeof(RamjetProfilerPostProcessedAssemblyAttribute).GetConstructor(Type.EmptyTypes));
var attribute = new CustomAttribute(attributeConstructor);
var ramjet = moduleG.ImportReference(typeof(RamjetProfilerPostProcessedAssemblyAttribute));
if (assembly.HasCustomAttributes)
{
var attributes = assembly.CustomAttributes;
foreach (var attr in attributes)
{
if (attr.AttributeType.FullName == ramjet.FullName)
{
Debug.LogWarning("<color=yellow>Skipping already-patched assembly:</color> " + assembly.Name);
return false;
}
}
}
assembly.CustomAttributes.Add(attribute);
foreach (var module in assembly.Modules)
{
foreach (var type in module.Types)
{
// Skip any classes related to the RamjetProfiler
if (type.Name.Contains("AssemblyPostProcessor") || type.Name.Contains("RamjetProfiler"))
{
// Todo: use actual type equals, not string matching
Debug.Log("Skipping self class : " + type.Name);
continue;
}
if (type.BaseType != null && type.BaseType.FullName.Contains("UnityEngine.MonoBehaviour"))
{
foreach (var method in type.Methods)
{
if ((method.Name == "Update" || method.Name == "LateUpdate" || method.Name == "FixedUpdate") &&
method.HasParameters == false)
{
var beginMethod =
module.ImportReference(typeof(Profiler).GetMethod("BeginSample",
new[] { typeof(string) }));
var endMethod =
module.ImportReference(typeof(Profiler).GetMethod("EndSample",
BindingFlags.Static |
BindingFlags.Public));
Debug.Log(method.Name + " method found in class: " + type.Name);
var ilProcessor = method.Body.GetILProcessor();
var first = method.Body.Instructions[0];
ilProcessor.InsertBefore(first,
Instruction.Create(OpCodes.Ldstr,
type.FullName + "." + method.Name));
ilProcessor.InsertBefore(first, Instruction.Create(OpCodes.Call, beginMethod));
var lastcall = Instruction.Create(OpCodes.Call, endMethod);
FixReturns(method, lastcall);
changed = true;
}
}
}
}
}
return changed;
}
static void FixReturns(MethodDefinition med, Instruction lastcall)
{
MethodBody body = med.Body;
var instructions = body.Instructions;
Instruction formallyLastInstruction = instructions[instructions.Count - 1];
Instruction lastLeaveInstruction = null;
var lastRet = Instruction.Create(OpCodes.Ret);
instructions.Add(lastcall);
instructions.Add(lastRet);
for (var index = 0; index < instructions.Count - 1; index++)
{
var instruction = instructions[index];
if (instruction.OpCode == OpCodes.Ret)
{
Instruction leaveInstruction = Instruction.Create(OpCodes.Leave, lastcall);
if (instruction == formallyLastInstruction)
{
lastLeaveInstruction = leaveInstruction;
}
instructions[index] = leaveInstruction;
}
}
FixBranchTargets(lastLeaveInstruction, formallyLastInstruction, body);
}
private static void FixBranchTargets(
Instruction lastLeaveInstruction,
Instruction formallyLastRetInstruction,
MethodBody body)
{
for (var index = 0; index < body.Instructions.Count - 2; index++)
{
var instruction = body.Instructions[index];
if (instruction.Operand != null && instruction.Operand == formallyLastRetInstruction)
{
instruction.Operand = lastLeaveInstruction;
}
}
}
basically what it does is to add a Ret instuction, but then replace all the previous Ret (usually one, why should it be more than one?) with a Leave function (don't even know what it means :) ), so that all the previous jumps remain valid. Differently than the original code, I make the Leave instruction point to the EndSample call before the last Ret
I am using tree.Panel with TreeStore when I call
sel_node.parentNode.appendChild(node);
tree.getSampleStore().sync();
ExtJS fire event called sample store proxy: update url instead of create url what could I have done wrong?
What exact version of ExtJS4 do you use?
In my situation, with ext-4.0.7-gpl, I debugged a bit a found out that appendChild method creates a node from and object and then performs some update operations concerning the node's position in the tree, like setting next sibling, parent etc., see [1].
When syncing, the store uses getUpdatedRecords and getNewRecords [2] methods to determine which operation to run. update or create. Somehow, our appended children turn out to be updated, not created.
Note that the method doesn't check whether the children of a parent node was loaded, just pushes the new node into an empty childNodes array; after all these operations end, other children of a parent node are never shown in the tree; and if the update operation caused the serverside generation of new id, the code breaks on the line original = me.tree.getNodeById(record.getId()); - there is no such node with the old id generated on client side..
Simply put, I think it's a bug.

Add: ExtJS 4.1 beta 2 doesn't work better for me
Update with temp solution: I hacked a bit and think I solved the issue by overriding the appendChild method of NodeInterface like below (just to set phantom property so that the record becomes created, not updated).
Please note:
1) You should include your appendChild call in the NodeInterface expand method callback, or the bug with pushing to the empty childNodes will remain: the new node will appear somewhere in the wrong place;
2) I had to override updateIndexes of the AbstractView as well, try not to do this and maybe you'll find out why;
3) there are some issues when the store tries to delete our newly created node the next time it syncs - couldn't trace it yet;
0) I am no way ExtJS or even JS guru, so feel free to correct this hack)
Ext.data.NodeInterface.oldGpv = Ext.data.NodeInterface.getPrototypeBody;

var me = this,

this is my code to add a node by values taken from a form domainForm. The form opens by clicking an icon in an actioncolumn of our tree grid:
var node = grid.store.getAt(rowIndex);
node.expand(false, function(){
var newDomain = domainForm.getValues();
newDomain.parent = {id: node.raw.id}; // i don't know whether you'll need this
var newNode = node.appendChild(newDomain);
me.store.sync();
});
and updateIndexes overrider:
Ext.override(Ext.view.AbstractView, {
updateIndexes : function(startIndex, endIndex) {
var ns = this.all.elements,
records = this.store.getRange(),
i;
startIndex = startIndex || 0;
endIndex = endIndex || ((endIndex === 0) ? 0 : (ns.length < records.length?(ns.length - 1):records.length-1) );
for(i = startIndex; i <= endIndex; i++){
ns[i].viewIndex = i;
ns[i].viewRecordId = records[i].internalId;
if (!ns[i].boundView) {
ns[i].boundView = this.id;
}
}
}
});
Had the same issue, an update to ext-4.1.0-beta-2 fixed it.
The reason might be wrong format of data that comes from the server in response to your request.
Syncronization doesn't happen. Pass 'success' key with the value of TRUE in the server response.
Hmm ... try this ...
beforeitemexpand(node, eOpts){
if (node.data.expanded) return false
}
