I'm wanting to write a script to rename files with 6 uppercase alphanumeric characters.
Example:
001.jpg
002.jpg
003.jpg
KT7S89.jpg
ZTY1S5.jpg
U2L7HP.jpg
By adapting other scripts I got the following code, but it doesn't work, could you help me once more?
function OnClick(clickData) {
var cadenaAleatoria {
var caracteres = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
var aleatoria = "";
for (var i = 0; i < 6; i++) {
var aleatoria = caracteres(Math.floor(Math.random() * caracteres.length));
}
}
var cmd = DOpus.Create().Command;
cmd.RunCommand('Rename IGNOREEXT PATTERN * TO aleatoria');
}
var aleatoria = caracteres(Math.floor(Math.random() * caracteres.length));
Change to aleatoria += caracteres[Math.floor(Math.random() * caracteres.length)];
And variable should be outside quotes. cmd.RunCommand('Rename IGNOREEXT PATTERN * TO ' + aleatoria);
function OnClick(clickData) {
var caracteres = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
var aleatoria = "";
for (var i = 0; i < 6; i++) {
aleatoria += caracteres[Math.floor(Math.random() * caracteres.length)];
}
var cmd = clickData.func.Command;
cmd.RunCommand('Rename IGNOREEXT PATTERN * TO ' + aleatoria);
}
Oh @WKen! You save my life again, I don't know how to thank you so much, thank you very, very much, but I wanted to ask you one thing, if I rename the photos one by one everything is perfect, but if I select several, after renaming the first one a message is generated error "Cannot create a file that already exists." How could I resolve that situation?
var sourcetab = clickData.func.sourcetab;
var sourcepath = sourcetab.path;
var cmd = clickData.func.Command;
var fsu = DOpus.FSUtil;
for (var e = new Enumerator(sourcetab.files); !e.atEnd(); e.moveNext() )
{
eItem = e.item();
}
cmd.Run();
function randChars() {
var caracteres = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
var aleatoria = "";
for (var i = 0; i < 6; i++) {
aleatoria += caracteres[Math.floor(Math.random() * caracteres.length)];
}
return aleatoria
}
@WKen take a look here, please, to see if I'm doing something wrong because it's giving an error on the line while (fsu.Exists(newFile)) {newFile is not defined?
function OnClick(clickData) {
var sourcetab = clickData.func.sourcetab;
var sourcepath = sourcetab.path;
var cmd = clickData.func.Command;
var fsu = DOpus.FSUtil;
for (var e = new Enumerator(sourcetab.files); !e.atEnd(); e.moveNext() )
{
eItem = e.item();
}
while (fsu.Exists(newFile)) {
aleatoria = randChars();
newFile = sourcepath + "\\" + aleatoria + eItem.ext;
}
function randChars() {
var caracteres = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
var aleatoria = "";
for (var i = 0; i < 6; i++) {
aleatoria += caracteres[Math.floor(Math.random() * caracteres.length)];
}
cmd.Run();
return aleatoria
}
}
I misplaced it. cmd.Run();
You didn't define newFile first.
And put it into a for loop: cmd.AddLine('Rename IGNOREEXT "' + eItem + '" TO ' + aleatoria);
If you're renaming things, you're probably better off using a rename script. Then you only have to worry about generating the filenames you want, and not everything else like which files to work on.
Thank you very much @Leo again, thanks to your brilliant idea we made it very simple. Thank you very much too @WKen for the hard and constant work, I don't know how to thank you so much!
In case the code interests anyone, it is to be used from the Advanced Renaming window.
function OnGetNewName(getNewNameData) {
var item = getNewNameData.item;
var caracteres = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
var random = "";
for (var i = 0; i < 6; i++) {
random += caracteres[Math.floor(Math.random() * caracteres.length)];
}
var name= random + item.ext;
return name;
}
Note: In the "Function" field we must select the option "Standard function (Opus or external)", not "Script function", even if it really is a script.
Rename PATTERN * TO *
@script jscript
function OnGetNewName(getNewNameData) {
var item = getNewNameData.item;
var caracteres = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
var random = "";
for (var i = 0; i < 6; i++) {
random += caracteres[Math.floor(Math.random() * caracteres.length)];
}
var name= random + item.ext;
return name;
}
To include lowercase letters: var caracteres = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
To include only numbers: var caracteres = 0123456789';
To change the number of characters, for example, from 6 to 12, change: for (var i = 0; i < 6; i++) { for for (var i = 0; i < 12; i++) {
You can also save the script into a Rename Preset and run that from a button (or from the menu on the right of the standard Rename button, which lists all your rename presets automatically).
That way you can use the same script inside the Rename dialog and outside it, without defining everything twice.
