As a professional computer programmer with 15 years of experience, I would translate this as "text editor/compiler (IDE)".

Irene Schlotter said she didn't think "Text-Kompiler Editor" looks like very good German. I think she's right about that!

The correct German would surely have been "Compiler/Texteditor (IDE)" or less commonly "Kompilierer/TextEditor (IDE)". TKE looks to me like a made-up acronym that's not in common use in German.

There are two reasons why I would translate this as "text editor/compiler", rather than "text compiler/editor":

1) Editing the text of a computer program precedes compiling it. Consequently, it is more natural to speak of a "text editor/compiler".

2) Computer programmers don't talk say "text compiler", they simply say "compiler". However, text editor is a perfectly good compound noun, so again it is natural to speak of a "text editor/compiler".

Compiler and Texteditor in German are of course borrowed from English. These terms refer to two distinct kinds of computer programs. They are also often used to refer to two distinct sets of features within a more complicated computer program known as an IDE (which stands for "integrated development environment").

An IDE which is fairly simple, and does not have many features besides those of a simple text editor and a compiler, would be referred to in English as a "lightweight IDE".

The slash and the acronym in your source text both imply that it is referring to a single program, i.e., an IDE.

Bear in mind that lightweight is a highly subjective term. An IDE which feels perfectly lightweight to one programmer, will feel absurdly bloated to another. I would avoid therefore including "lightweight" in the translation, unless your source text strongly emphasizes that aspect.

Hence, "text editor/compiler (IDE)".
