When you unzip it, the archive is set up with directories where you can install put the executables for the compilers and interpreters and also the library files for the supported authoring systems. However, you can also edit the configuration file (there’s a different one for each IF system) to point it to the path on your hard drive where you have your compiler and interpreter, and you can set compiler switches in the configuration file to point to the IF system’s library location, so you don’t need to put everything in Implementor’s directiory. When you launch the compiler from Implementor, any error messages are saved and displayed in a pane below the source code. The commands to compile or run the compiled gamefile are found in the menu produced when right-clicking.
Implementor also comes with indexes that explain the keywords, commands, library routines, ect. in each of the systems. These are displayed when you press F1, or from the menu. However, this reference material is probably not up to date with the latest versions. It’s definitely not current with the latest release of Hugo, but it’s still helpful.
You can edit the configuration file for the system that you’re working with inside of Implementor without needing to restart it. There’s a Configure command on the menu, which opens the configuration file. You can make any changes necessary, and when you close it, Implementor displays “Configuration Updated”, apparently having re-loaded the saved file.
Implementor has other features, but many of them are probably standard to programming text editors (commenting/uncommenting source code and increasing/decreasing indent, for instance). It may have other features that I don’t know how to use, but it’s not really all that complicated. Unfortunately, it doesn’t seem to be able to match braces.
Its interface is definitely retro; it looks like it could have been a GUI DOS program, or maybe Windows 3.1. However, it has all the functionality of more modern applications, including re-sizable panes.
It’s definitely a very capable piece of software, probably one of the best applications made specifically for creating IF. I alternated between using Implementor and ConTEXT for “Dreary Lands”, and I think for another Inform 6 project that I never finished. I’ve also been using it for Hugo, but I’ll probably switch to ConTEXT eventually, because I’m more comfortable with it in general.
