In my old CEP code I had a function selectOrCreateChannel
The way it worked was it was trying to select a channel and if there was an exception, it was creating a new channel.
I tried to do the same with UXP and instead of exception it’s now a popup dialog saying that “select” command is not currently available.
What would be a correct way to build this function in UXP/batchPlay?
batchPlay returns a promise if you have the option set to "synchronousExecution": false
That means you can use something like
.then(result => {console.log(result)}, error => {console.log(error)})'
to handle whatever the promise returns.
I am using await syntax to execute a promise. In this case it should throw all errors as exceptions.
I am not getting any exceptions, only the dialog message
Here is a batchPlay I try to execute
async create(name, selectIfExists) {
l.log("create", name, selectIfExists)
if (selectIfExists) {
try {
await this.select(name)
} catch (e) {
l.info(e)
await _addChannel(name, false)
await this.select(name)
}
} else {
await _addChannel(name, false)
}
l.log("created", name, selectIfExists)
},
async select(name) {
return await batchPlay(
[
{
_obj: "select",
_target: [
{
_ref: "channel",
_name: name,
},
],
_isCommand: true,
_options: {
dialogOptions: "dontDisplay",
},
},
],
{
synchronousExecution: false,
modalBehavior: "fail",
}
)
},
certainly not the most elegant way, but maybe this is how it works
async function select(name) {
const result= await batchPlay(
[
{
_obj: "select",
_target: [
{
_ref: "channel",
_name: name,
},
],
_isCommand: true,
_options: {
dialogOptions: "silent",
},
},
],
{
synchronousExecution: false,
modalBehavior: "fail",
}
)
if(result[0].message!=undefined){
create(name)
}else{}
}
const batchPlay = require(“photoshop”).action.batchPlay;
async function create(name, selectIfExists) {
console.log(“create”, name, selectIfExists)
if (selectIfExists) {
try { await this.select(name) } catch (e) { console.log.info(e) await _addChannel(name, false) await this.select(name) }} else {
await _addChannel(name, false)}
console.log(“created”, name, selectIfExists)
}
async function select(name) {
const result= await batchPlay(
[ { _obj: "select", _target: [ { _ref: "channel", _name: name, }, ], _isCommand: true, _options: { dialogOptions: "silent", }, }, ], { synchronousExecution: false, modalBehavior: "fail", })
if(result[0].message!=undefined){
create(name)}else{}
}
async function _addChannel(name){
const result = await batchPlay(
[
{ "_obj": "make", "new": { "_obj": "channel", "colorIndicates": { "_enum": "maskIndicator", "_value": "maskedAreas" }, "color": { "_obj": "RGBColor", "red": 255, "grain": 0, "blue": 0 }, "opacity": 50 }, "_isCommand": true, "_options": { "dialogOptions": "dontDisplay" } }, { "_obj": "set", "_target": [ { "_ref": "channel", "_enum": "ordinal", "_value": "targetEnum" } ], "to": { "_obj": "channel", "name": name }, "_isCommand": true, "_options": { "dialogOptions": "dontDisplay" } }],{
"synchronousExecution": false, "modalBehavior": "fail"});
}
select(“try”)
I found that the problem is in
_options: {
dialogOptions: "dontDisplay",
},
If I delete this part then no dialogs show anymore.
This code was generated by Alchemist, so I assumed it’s the way to go.
Another thing that I now don’t understand is how to find out that there was an error.
At the moment I just check if message is present in the batchPlay result and if it is – throw it as an exception
