Main Innosetup site down; downloads are now at GitHub thanks to Martijn Laan

Posted by jpluimers on 2018/06/22

Earlier this week, I wanted to install the most recent version of InnoSetup, but found out the main site at is down.

The new versions released earlier this month were on my list of things to try:

There WayBack archive editions of most directories but all of them are too old to hold the 5.6.0 or 5.6.1 versions (some do not even have the 5.5.9 version either).

In the mean time, Martijn Laan has provided the most recent binaries on GitHub:

Parallel to that, I have archived or found back the most recent versions of these pages and downloads:

I wish the Delphi language supported multi-line strings

Posted by jpluimers on 2018/06/21

Very often, I see people ask for how to embed multi-line strings in a Delphi source file.

The short answer is: you can’t.

The long answer is: you can’t and if you want you have to hack your way around.

The answer should be: just like any of these languages that do support multiline strings:

Many languages support this through a feature called HEREDOC.

Now in Delphi and other languages like Java are building ugly workarounds like for instance this one: [WayBackRAD Studio Tip: Using resource scripts to organize project dependencies. – Chapman World.

The Spilled Juice Analogy for Technical Debt | Disciplined Agile 2.X

Posted by jpluimers on 2018/06/21

Interesting take on Technical Debt: [WayBackThe Spilled Juice Analogy for Technical Debt | Disciplined Agile 2.X

Not just because of the analogy, but also because of this comment by Ramu Iyer:

Conway’s Law states that software (or the structure of an IT system) mimics and is isomorphic to the organizational-social structure around it. In layman’s terms, a poorly designed software system is a vivid indicator of the underlying pattern of team communication, coordination and cooperation in the software team. Oftentimes, strained social and organizational interactions get in the way of smooth software development and operation. This results in social liabilities during intergroup coordination and accumulates “social debt” within or across one or more communities in a (software) organization. Any suboptimal socio-technical decisions also impact the technical debt of a software system in tandem. Digging one’s “way out of the technical debt pit” also requires the proactive mitigation of social debt around a system.

Two cool features of the TestInsight treeview – navigate and copy

Posted by jpluimers on 2018/06/20

TestInsight is a great tool for automatically running your unit tests and seeing the results to make you more productive.

Two of the results treeview features you might not know make you even more productive:

  • After selecting a node, pressing Ctrl-C will copy the content as text to the clipboard
  • Double clicking will bring you to the unit test in your source code

You can get TestInsight at sglienke / TestInsight — Bitbucket

Class helpers and virtual methods – E2003 Undeclared identifier: ‘QueryInterface’/ ‘_AddRef’/’_Release’

Posted by jpluimers on 2018/06/20

Reminder to self: if you want to stay compatible with old (Pre Delphi XE) source code, then do not use virtual methods in class helpers.

Technically you can, as class helpers can inherit from other class helpers, but this is only supported as of Delphi XE.

In lower versions you get these errors as apparently the Delphi compiler tags an IInterface to the class helper compiler result:

[Error] Project1.dpr(14): E2003 Undeclared identifier: 'QueryInterface'
[Error] Project1.dpr(14): E2003 Undeclared identifier: '_AddRef'
[Error] Project1.dpr(14): E2003 Undeclared identifier: '_Release'
