This post is a follow up to "Programmatic text formatting in Google Sheets with Google Apps Script"

Starting from where I left off in my last post, I had just started getting the basic bits and pieces wired together for this. A few months on, I've built out the concept into a more maintainable project.

Nothing much has changed in the Google Apps Script, aside from it no longer ignoring blank cells. A lot of work has gone into the internals of the Node JS based API it uses. I've nicknamed the API loquor meaning "I speak" in latin, as this project originally was to be used for generating translation request files for our multi-lingual products.

I changed a few things to make unit tests a bit easier to work with, however the I/O hasn't changed. It still accepts a string of values and returns indices of substrings that should be formatted by the Google App Script. The API is generally more stable now, fully unit tested, and has had its internal logic broken into "rule-sets" to make maintenance a bit easier.

const input = ["<p>Cat</p>", "{{ dog }}", "% Parrot %"];

const results = await fetch(
    'method': 'post', 'payload': {
      'entries': JSON.stringify(input)
.then(response => response.json())
.catch(error => console.log('error', error));

// [ [[0,3],[6,10]], [[0,9]], [[0,10]] ]

Next steps

With the basics finished it is time to polish this into something I can share with others, ideally as an out-of-the-box service/solution. Here is a breakdown of what I want to work on next:

1. Set up options

I want to add UI element to show on the menu button trigger that lets users change some basic configuration before the script processes their document. Things like the input/output ranges and even the API server endpoint. This would reduce the need for me to edit the script file to make basic changes here and there. I currently only seem to edit it to change my API URL and the input range length. I have a feeling a nice native dialog would be a good solution for this.

2. Figure out distribution

The script is isolated to a single document currently, my test sheet. I will need to look into how to distribute this script to a wider audience, starting with just our Google Org for now.

3. More complete testing

The API is fully unit tested, but I feel the need to expand the tests by testing it with the most complex test cases we have available. The initial test found only two incorrect results which currently have issues opened (#6 & #7). TDD is the future, and the future is now. Long term goal is to work out how to automate tests for the Google Apps Script part.
