My Delimiter tool is now live. I often use a delimiter tool when working with SQL/SOQL queries. I query record ids from the database, and use a delimiter to format them to be used in another query. It is a simple and very straight forward tool, yet very useful - so I decided to build my own.
Why did I build my own delimiter tool?
There are hundreds of delimiter tools online, did you really have to build another one? No, absolutely not. But - owning as much as I can is what motivates me towards excellence. I build my own tool whenever possible for a few reasons: 1) The fact that I can put my name on it is motivating. If it has my name on it, then I am driven to make it presentable and stand out from other tools online. It is reflection on me, and that reflection must be very positive. 2) It is my tool, so with time as I learn new methods and grow as a developer, I will continue to revisit the tool and improve it. The fact that I own the tool means that even when working on other projects I will still be looking for ways to optimize it, enhance it and improve it overall. 3) It is very satisfying when using something that you have built yourself that is genuinely useful. I will be proud every time I return to use it.
