A special thanks goes out to manassharma07 who made the dictionary files I'm using for this feature.

New Feature: Spell Checking

After my last post, and the subsequent comments on the spelling of contemplate and the missing r in yourself. I decided the next update needed the all important spell checker. This feature caused me to have to re-work a lot of my code in most areas of the program. Thankfully, I use the same qml object file FieldEdit.qml for most of the editing operations.


The core of the feature is found in the plugins directory in the spellcheck.js file. This file depends on the files found in "Dictionary in csv" folder found in the same directory as spellcheck.js for word search. This javascript file has only one function checkspelling(string) the logic is pretty straight foreword her is the complete loop sans code.

  • Split the string into an array
  • change case, trim, and remove special characters, from the array object to standardize input
  • check the first letter of the word to choose proper dictionary file to load
  • Load dictionary file
  • Split the file into individual definitions.
  • Split this array object into just the word.
  • change case, trim, and remove special characters from this array object and check it against the word within the original string.
  • If strings match break and go to the next item
  • If no strings match highlight the word in red

The last part of the function required me to reformat the text area within FieldEdit.qml, and most of the files in the Template directory, changing the plain text into rich text which then required me to change the markdown.js file to look for and interpret the different versions of the data now in the database. Unfortunately and most likely due to the fact that this data isn't in a database but in files that must be read each time the spellcheck function is run I had to resort to creating a timer (see code below) to wait for typing to stop before the function is run.

    Timer {
        interval: 2000
        repeat: false
        running: true
        onTriggered: {
            thestring = changeBox.getText(0,changeBox.length).replace(/<font color='red'>/g,"").replace(/<\/font>/g,"")
            changeBox.text = Spelling.checkspelling(thestring)
            changeBox.cursorPosition = changeBox.length

Other changes

There were a few minor changes to how things at some timing issues were tweaked and the weekly report template is slowly coming together. I've been trying to keep my updates and work more focused as I now have limited time to code on this or any project. However, the next update should have a good amount of features in it as they will be built around the above as well as clearing out tickets in the system.

This project is first and foremost for my classroom and the benefit of my students. It is my hope that when complete other families and schools will adopt the software, and use it in their homes as well. The feature list isn't set in stone but here are a few of its current and planned features:

  • School management including calendars, Courses, Students, and Teachers
  • Lesson plan creation and publishing to STEEM and to an in application store for other teachers to download
  • Student reports created and published by the students through an semi-automated process
  • Auto review (Quizzes) based on review questions added to lessons
  • media storage via IPFS
  • Student rewards based on completion of assignments
  • Micro-scholarships provided by the up-votes the student receives on their weekly posts

As with all my projects eduSteem is open source. Most if not all proceeds from utopian and steem are used for the continued development of this and my other software's and projects.

For further reading check out these other posts here on Steemit.

I also have a Patreon page here if you would like to show your support for the project. The proceeds will be used to maintain the house and my students education as Steemit and Patreon are my sole sources of income.

As always it is my hope that this software along with any of the other projects I have undertaken will be found useful to the community. I do this for the love of the challenge and the need for the software.
