[BUG] Better error reporting

[lslocum]

Overview of the issue

Came across an error on Process Page. The error that was printed out simply said TypeError: cannot read property 'text' of undefined. The page being processed did not reference a property of text. I placed a try catch around

        return this.compiledPage({
            data: o
        });

in HtmlEngine.prototype.render. This provided me the full stack trace I used to find where the error was coming from. It would be nice if the stack trace was provided by default.

Operating System, Node.js, npm, compodoc version(s)

Win 10, Node v8.1.6, npm v6.2.0, compodoc v1.1.5

Compodoc installed globally or locally ?

locally

If possible sourcecode of the file where it breaks

Here is where the error was occuring BTW:

    FunctionSignatureHelper.prototype.handleFunction = function (arg) {
        var _this = this;
        if (arg.function.length === 0) {
            return "" + arg.name + this.getOptionalString(arg) + ": () => void";
        }
        var argums = arg.function.map(function (argu) {
            var _result = _this.dependenciesEngine.find(argu.type);
            if (_result) {
                if (_result.source === 'internal') {
                    var path$$1 = _result.data.type;
                    if (_result.data.type === 'class') {
                        path$$1 = 'classe';
                    }
                    return "" + argu.name + _this.getOptionalString(arg) + ": <a href=\"../" + path$$1 + "s/" + _result.data.name + ".html\">" + argu.type + "</a>";
                }
                else {
                    var path$$1 = _this.angularVersionUtil.getApiLink(_result.data, _this.configuration.mainData.angularVersion);
                    return "" + argu.name + _this.getOptionalString(arg) + ": <a href=\"" + path$$1 + "\" target=\"_blank\">" + argu.type + "</a>";
                }
            }
            else if (_this.basicTypeUtil.isKnownType(argu.type)) {
                var path$$1 = _this.basicTypeUtil.getTypeUrl(argu.type);
                return "" + argu.name + _this.getOptionalString(arg) + ": <a href=\"" + path$$1 + "\" target=\"_blank\">" + argu.type + "</a>";
            }
            else {
                if (argu.name && argu.type) {
                    return "" + argu.name + _this.getOptionalString(arg) + ": " + argu.type;
                }
                else {
                    return "" + argu.name.text; // this is the breaking line when the anonymous function does not name its parameter
                }
            }
        });
        return "" + arg.name + this.getOptionalString(arg) + ": (" + argums + ") => void";
    };

Suggest a Fix

Put some try catches with error logging to get the full stack trace. Maybe also have a wiki that has some troubleshooting tips.

thanks for the informations
can i have the source code of the file which had his rendered page broken ?

[lslocum]

public openSomeDialog(model, grid, callback: ({ index }) => {}): void {
  ...
}

Since the parameter to the callback method wasn't named argu.name was undefined and agru.type was ''. When I gave the parameter a name the error was resolved. It now looks like this

public openSomeDialog(model, grid, callback: (event: { index }) => {}): void {
  ...
}
