Compodoc installed globally or locally ?

globally

Motivation for or Use Case

I would like to generate the doc

Reproduce the error

Command line used :
compodoc -p .\src\tsconfig.app.json

Here is the component for which it fails. If I remove all the class content, the doc is generated successfully:

import { Component, Input, OnDestroy  } from "@angular/core";

@Component({
    selector: "loading-helper",
    templateUrl: "loading-helper.component.html",
    styleUrls: ["loading-helper.component.scss"]
}) 
export class LoadingHelperComponent implements OnDestroy  {

    public visible: boolean = true;
    public timeout: any;

    /**
    * @description : if needed, we can wait before showing the spinner
    **/
    @Input() delay: number = 0;

    /**
    * @description : The text above the spinner ("loading", "no results", etc)
    **/
    @Input() feedback: string;

    @Input() public set isRunning(value: boolean) {
        if (!value) {
            this.cancel();
            this.visible = false;
            return;
        }

        if (this.timeout) {
            return;
        }

        this.timeout = setTimeout(() => {
            this.visible = true;
            this.cancel();
        }, this.delay);
        
    }

    private cancel(): void {
        clearTimeout(this.timeout);
        this.timeout = undefined;
    }

    ngOnDestroy(): void {
        this.cancel();
    }
}

@Robouste Just tested your component code inside the demo project (https://github.com/compodoc/compodoc-demo-todomvc-angular).
I have just delete all the modules/component, only keep app.component.ts, and copy-pasted your code. No problem for me.

Can i have your terminal logs ?

[Robouste]

Is there a command to output the log to a file ? I don't know how to give them to you

[vogloblinsky]

The issue happens in latest version (1.0.0-beta.10). And it is related to Input and Output decorators (just remove them and the parsing process goes next).
Downgrading to 1.0.0-beta.9 helps.

[vogloblinsky]

@didevgen
Do you have an example of failing @input or @output ?

[Robouste]

I can confirm it's working with version 1.0.0-beta.9

@didevgen
Thanks for the pastebin links, but i cannot reproduce it without all the files listed. As TypeScript parser handles them, just copy-pasting your @output example didn't failed for me.

Is it possible to clean as possible the AccountLookupComponent with just the code which breaks, all if possible too the files imported ?

I will try to reproduce it with the compodoc demo project.

Thanks

@vogloblinsky
Hello!
Here is the pastebin with no project imports: https://pastebin.com/VSGRrLtg

I've used 1.0.0.beta.10 version and my parsing process stoped and here is the output in console: https://pastebin.com/y87PQfe1

[vogloblinsky]

@didevgen
Still no failing when i copy-pasting your AccountLookupComponent in a new file. 😡

Can you please create a zip of your cleaned and failing project ?

Thanks by advance.

[didevgen]

@vogloblinsky
I'm sorry, but I can't, because it is not my own project.

I tried also to add the copy of failed component into the same folder, and I unexpectedly found, that it had been parsed successfuly, but the original one failed.

I can just tell, that not all files which have @input or @output decorators are failed.

[tme321]

Just adding my 2 cents in, having the same issue. A single file, if I remove the code from it everything else works and docs get generated. With this file it doesn't work.

https://github.com/tme321/Unopinionated-Angular/blob/master/src/lib/dropdown-input/dropdown-input-item-list.component.ts

[shwedberlin]

Similar issue in my project: RangeError: Invalid array length, but no UnhandledPromiseRejectionWarning
I have also @input and @output directives in failed file.
Project: https://github.com/shwedberlin/AngularWebApi

[vogloblinsky]

@shwedberlin : ok bug found, in @input/@output parsing, fixed for your project.
Coming in next release 1.0.0-beta.13

@tme321 In which folder of your repository do you run compodoc ?
EDIT : i have tested src/lib folder, same bug as @shwedberlin.

[tme321]

Honestly I didn't get far enough to figure out where exactly to run compodoc. Ideally it would just be /src/lib but I was just trying to get it to work pointed at /src.
