Programming

You've probably used Delphi's Find in Files feature to search for an identifier or library function through multiple folders of source code. If you have backups of your source or multiple projects with copied or similar sets of routines and check the "Include subdirectories" checkbox, the search results could contain a lot of duplicates taking extra time to wade through them all. Wouldn't it be nice if there was a way to fine-tune the folders being searched?

There is!

In my last blog entry, I explained how I converted my original company logo in JPG format to SVG. That's sort-of like reverse-engineering to get the source code. Now that I have my logo in SVG format, I can more easily manipulate it and create custom derivations for specific purposes.

I've been hearing a lot about SVG, or Scalable Vector Graphics, lately and how much better they are than bitmap formats such as JPG or PNG for icons or simple images because they scale up or down to fit the plethora of devices we use today.

Writing REST applications in Delphi is pretty simple with the advanced components we have available these days. The functionality encapsulated allows us to spend time on the business and user interface aspects of development rather than the nuances of connecting to an API and parsing JSON results. When starting a new REST app, I usually use the REST Debugger that comes in RAD Studio to test out an API before building the app itself. There are other REST API tools but this one has a great feature that saves me time building my Delphi app that no other tool has.

At the top of Delphi's code editor, is a Navigation Toolbar with several "jump lists" as I like to call them. They help you find and jump to places in your code quickly by selecting them from lists built by the parsing engine in Delphi. There are also shortcut keys that allow you to use them without taking your hands off the keyboard to use the mouse.

RAD Studio 11 Alexandria was released Thursday. There were webinars, blog posts, and tweets about the many wonderful things in the latest major release of Delphi and C++Builder from Embarcadero. These include High-DPI support in the IDE, design-time style viewing in VCL applications, support for Windows 11, ARM-64 compilation on Apple's new M1 chip, and many other features and enhancements. I installed the update and did a little bit of coding to get a feel for how well it behaves and am quite pleased. I'll be using it more over the next several days and weeks as I shift my development, install plugins and components, and tweak the settings to tune my new work environment. Here are just a few things I noticed right away.

This week's Desktop First UX Summit, hosted by Embarcadero, is a great collection of presentations by leading software development and design professionals sharing the theory and practice of creating great desktop experiences. I really appreciate the focus on desktop app design--not everything is mobile or web. One of my favorite speakers every year is Ray Konopka and he gave another great talk, this year on How Tab Controls Can Ruin Desktop UX.

A couple of years ago, I blogged about my favorite new Delphi 10.3 Rio features, which included two plugins, originally by Parnassus but acquired by Embarcadero. I would like to highlight them again and go into a little more detail to continue in my "Delphi Productivity Tips" series.

A few weeks ago, I blogged about how simply installing RAD Server prevented access to my currently installed InterBase databases. I did some more testing and research to find out why--and see if I could get around it.

A long time ago when Delphi 5 was king and conferences were in person, I was able to attend BorCon and saw a session presented by Mark Miller. I don't remember the topic but I do remember noticing that he was typing code really fast. He wasn't just typing fast, though, he was coding fast! As he was typing, characters were being turned into words and sometimes even full expressions. At some point, he explained how he was doing it: he was using a Delphi IDE plugin called CodeRush.

I switch back and forth between doing cool new stuff with the latest version of Delphi on web and mobile platforms and supporting legacy apps that have been running for a long time but the original programmer has long since left. The project I'm working on today falls into the latter category and the current challenge is storing a letter template file in an old Advantage Database. My update to the software has be put into an installer script and sent out to non-technical customers to update their existing installed databases.

I've been watching a weekly webinar by Embarcadero, usually hosted by Jim McKeeth, called TCoffeeAndCode and today's topic was "Managing Large Projects and IDE Performance Enhancements". This one was packed full of tips and tricks for speeding up your development with IDE plugins, better use of the keyboard, managing projects, analyzing code, and so forth. Near the end, Jim called out to programmers everywhere to blog about their favorite productivity tips and share with others what works for them to speed up software development.

So I'm taking on this challenge for myself and am starting a mini series highlighting ways I use Delphi, the short-cuts I've found useful, my favorite plugins, and other tidbits I've picked up along the way. Perhaps you will find something useful. In this first blog on the topic, I'll talk about the built-in keyboard shortcuts Delphi provides in the editor and how I use them every day.

One of the legacy projects I support was written in Delphi 7 and uses ACE Reporter. I have only used ACE Reporter once before and very little even then so don't know much about it but it seemed to work fine for what it was doing. I was tasked with adding a column to a report where the data on the report came from a temporary table that gets filled every time it prints. Adding a column to the report implied adding a column to the table. A previous experience updating tables with this app proved to take an inordinate amount of time so I wanted to avoid that if possible.

I've been using a couple of small InterBase databases for testing and learning purposes while doing some mobile and web development. I have a Windows 2016 Server in my office with InterBase XE7 and 2017 installed using different ports. Since I work from multiple virtual machines and sometimes a laptop, I just put the databases on the Windows server to access them all from whichever development environment I happen to be using. Both InterBase instances on the server were using the Developer license that comes with Delphi--requiring a restart once a day.

A few days ago, I wrote about signing your commits so they'll show up on GitHub as verified. After that process is in place, every commit requires the passphrase associated with the signing key to be re-entered. This gets old quickly if you're committing frequently (which you should). Fortunately, there's a way to cache the passphrase to make this much less burdensome. Unfortunately, the cache only lasts 10 minutes.

Coming from a long history of Windows VCL development with Delphi, I have often used data-aware controls to quickly hook up data sets to controls and grids. As I've been doing more mobile development, I've taken a look at LiveBindings and like its extensibility. So, I decided to try my hand at extending it!
