Sorting index files above non-index files in list

[Jordan-Hataway]

I did it for myself just now and I really like it.
I added this bit to the main.js file in the updateIndexContent() function.

//CUSTOM SORT ORDER
if (sortOrder === SortOrder.CUST) {
    indexContent.sort((a, b) => {
	const aFlag = a.includes("_index_of_");  //This is my index prefix -- use yours here
	const bFlag = b.includes("_index_of_"); //This is my index prefix -- use yours here
	// If both are flagged, sort alphabetically
	if (aFlag && bFlag) {
		return a.localeCompare(b, undefined, { numeric: true });
	}
	// Flagged strings come first
	else if (aFlag) {
		return -1; // a comes before b
	} else if (bFlag) {
		return 1; // b comes before a
	}
	// Neither flagged, sort alphabetically
	else {
		return a.localeCompare(b, undefined, { numeric: true });
	}
    });
}

It's really nice to have all of the index files together, because in my mind they are very different from the other files. I don't like to have them all mixed in together. Might want to add this feature in, since it's really easy to implement. Otherwise, maybe this will be helpful to somebody!

Make sure to update the SortOrder enum:

var SortOrder;
(function (SortOrder) {
    SortOrder["ASC"] = "asc";
    SortOrder["DESC"] = "desc";
    SortOrder["CUST"] = "cust"; //ADD THIS
})(SortOrder || (SortOrder = {}));

...and to add the option in settings:

        new obsidian.Setting(containerEl)
            .setName('Index links Order')
            .setDesc('Select the order of the links to be sorted in the god damn index files.')
            .addDropdown(async (dropdown) => {
            dropdown.addOption(SortOrder.ASC, 'Ascending');
            dropdown.addOption(SortOrder.DESC, 'Descending');
            dropdown.addOption(SortOrder.CUST, 'Custom'); //AND ADD THIS
            dropdown.setValue(this.plugin.settings.sortOrder);
            dropdown.onChange(async (option) => {
                this.plugin.settings.sortOrder = option;
                await this.plugin.saveSettings();
            });
        });
