Advanced configurations in Yaydoc’s Web UI

Yaydoc’s User Interface consists of a form with three required fields; the user’s email address, git repository’s URL, and a theme for the generated website. Specific values of these fields are the minimum requirement to generate documentation for a project. There are certain other configuration variables for whom we assumed default values. Among these, we assumed `docs/` directory or the directory specified in the `yaydoc.yml` configuration file as the default path for the documentation. Also, `Default Branch` is assumed as the branch to generate documentation website. However, this cannot guarantee the generation of docs for every other project. These configurations can have different values based on a project.

Thus, there was a need to include certain input values for advanced configuration. The addition of these configurations in the UI doesn’t compel the user to specify them. In our attempt to improve user’s experience, we show the default values to the user when they are specifying custom values for these configurations.

If the user doesn’t specify a value for the repository’s branch, a default value is retrieved from Github’s Repository Components API, taking repository’s URL from the required input as the input URL.

 * Setting the branch name with `default_branch` attriburte from
 * Github’s Repository Components API
 * @param gitUrl: URL of the github repository
setDefaultBranchName: function (gitUrl) {
  var owner = gitUrl.split(“/”)[3] || ‘’;
  var repository = gitUrl.split(“/”)[4] || ‘’).split(‘.’)[0] || ‘’;
  $.get(‘’ + owner + ‘/’ + repository, {
    headers: {“User-Agent”: “Yaydoc”}
  }).complete(function (data) {

There are certain cases in which the design of the Web User Interface could have been confusing. Since we are displaying all the advanced configurations at once, it could’ve appeared to the users that they are specifying empty values for the other. Thus to handle this, inputs were enabled on toggle when a checkbox beside them was checked. This was achieved making following changes in the front end of the code.

 * Toggle editing of Branch Name input
$(“#btnEditBranch”).click(function () {

 * Toggle Enabling/Disabling an input tag
 * @param id: `id` attribute of input tag
toggleEditing: function (id) {
  const input = $(‘#’ + id);
  if (input.attr(‘disabled’)) {
    $(‘#checkbox_’ + id).removeClass(‘glyphicon-unchecked’).addClass(‘glyphicon-check’);
  } else {
    input.attr(‘disabled’, ‘disabled’);
    $(‘checkbox_’ + id).removeClass(‘glyphicon-check’).addClass(‘glyphicon-unchecked’);

Introducing advanced configurations to the User Interface has opened the possibility for even more projects to generate and deploy docs with much lesser constraints. One of our main aim for this project is to have a fairly simple UI and UX and we hope to bring further updated to achieve that.

Open Event Server: No (no-wrap) Ellipsis using jquery!

Yes, the title says it all i.e., Enabling multiple line ellipsis. This was used to solve an issue to keep Session abstract view within 200 characters (#3059) on FOSSASIA‘s Open Event Server project.

There is this one way to ellipsis a paragraph in html-css and that is by using the text-overflow property:

white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;

But the downside of this is the one line ellipis. Eg: My name is Medozonuo. I am…..

And here you might pretty much want to ellipsis after a few characters in multiple lines, given that your div space is small and you do want to wrap your paragraph. Or maybe not.

So jquery to the rescue.

There are two ways you can easily do this multiple line ellipsis:

1) Height-Ellipsis (Using the do-while loop):

if ($('.div_class').height() > 100) {
    var words = $('.div_class').html().split(/\s+/);

    do {
        words.splice(-2, 1);
        $('.div_class').html( words.join(' ') );
    } while($('.div_class').height() > 100);

Here, you check for the div content’s height and split the paragraph after that certain height and add a “…”, do- while making sure that the paragraphs are in multiple lines and not in one single line. But checkout for that infinite loop.

2) Length-Ellipsis (Using substring function):  

$.each($('.div_class'), function() {
        if ($(this).html().length > 100) {
               var cropped_words = $(this).html();
               cropped_words = cropped_words.substring(0, 200) + "...";

Here, you check for the length/characters rather than the height, take in the substring of the content starting from 0-th character to the 200-th character and then add in extra “…”.

This is exactly how I used it in the code.

$.each($('.short_abstract',function() {
   if ($(this).html().length > 200) {
       var  words = $(this).html();
       words = words.substring(0,200 + "...";

So ellipsing paragraphs over heights and lengths can be done using jQuery likewise.

KISS Datatable

Recenlty I’ve faced a problem with sorting columns in Datatable.

What is Datatable?

Datatable is a plug-in for Jquery library. It provides a lot of features like pagination, quick search or multi-column ordering. Besides, you can develop easily Bootstrap or Foundation ui css styles. There are also more other option but It doesn’t make sense to list it here, because you can visit their site and you can read clearly documentation. On Datatable website you can see a lot of examples. First of them shows how to improve your ordinary table to awesome and rich of features table. One function changes everything, It’s fantastic!  


Returning to my problem which I’ve faced, as I told it was problem related to sorting column in table.

I know sorting is a trivial thing. I hope that everyone knows it 🙂 Sorting by a date is also implemented in a datatable library. So everything is clear when we don’t change date format to human readable format. I mean something like this ‘3 hours ago’, ‘1 year ago’.

When Open Event team tested how datatable manages ordering columns in that format it didn’t work. It’s quite hard to sort by that format, So I’ve invented an idea. Surely you are wondering what i’ve invented. I’ve postponed my minds about sort by this values. It can direct to overwork. When I thought about it, weird ideas came to my mind, a lots of conditions, If statements… Therefore I’ve resigned from this. I’ve used KISS principle. KISS means ‘keep it simple stupid’. I like it!

Therefore that sorting is implemented on frontend side. I’ve decided not to display human readable date format at the beginning. I find  all dates which have format “YYYY-MM-DD HH:mm” then I replace that format to human readable format. So it’s very quick and comfortable, and doesn’t require a lot conditions to write. Of course I’ve tried to implement it in Datatable library. I suppose that it would  require more effort than it’s now.

Below You can see great function which changes a date in frontend side but does not change data in a datatable. So sorting process takes place in a datatable using format  “YYYY-MM-DD HH:mm” but user see human readable format. Isn’t it awesome?!

function change_column_time_to_humanize_format(datatable_name, column_id) {
  $(datatable_name).each(function( key, value ) {
    $(value).children().each(function( key1, value2 ) {
       if(key1 === column_id ){
          var current_value = $(value2).text().slice(0, 16);
          var changed_value = moment(current_value, "YYYY-MM-DD hh:mm").fromNow()
          var isValid = moment(current_value, "YYYY-MM-DD HH:mm", true).isValid()
          if (changed_value !== current_value && isValid === true){

Creating Dynamic Footer with Popover

In Open-Event Webapp generator, the track page height varies according to the popover that appears on hovering the tracks. The problem with this design was the footer of the page that always remains static and produce a bad UI to user.


So, I have decided to make footer dynamic so that it varies it’s position according to the popover appeared on hover. The approach was a bit tricky but the diagram below will make it easy to understand.

Dynamic footer

The following code will work on hovering the track.


var outerContheight= $('.main').offset().top + $('.main').outerHeight();
var tracknext= $(track).next();
var tracktocheck= track.offset().top + track.outerHeight() + 
 tracknext.outerHeight() + 15;
 var shift= tracktocheck - outerContheight;
 if(shift > 0){
 'top': outerContheight + shift,
 'z-index': '999'

If shift > 0 which is calculated as shown in the above code it means that the footer needs to be shifted and hence we shift the footer by setting absolute position in CSS. Else we set position: static for footer.


After following the above approach the footer position changes according to the popover. Here is the screencast for the approach.
