SciTE vs JetBrains Rider

It's property files allow for fine tweaks of its behavior, at a global or per language / project level. These textual settings might be confusing for those used to preference dialogs, but prove to be powerful, flexible, and fine grained.

With less than 2 MB of binary on Windows, SciTE starts instantly. Plus, if you don't need all the config, syntax files, blah, there's a 678k standalone .exe version. Nothing is going to beat that for lightweight and start-up times. Stick it in a folder that is already on your PATH.

Based on the Scintilla source code editor, SciTE has some advanced features like rectangular editing, simple regular expression search and replace, code folding, etc. It allows the user to launch a compiler or interpreter, and it can also interpret the error messages, jumping at the location they point to.

Lua scripting is key to SciTE's power and flexibility. The Lua scripting language can be used to perform complex text transformations. It's relatively simple syntax and its large user-base makes it a great choice for a scripting feature.

The console window can show the result of ran commands (like build current file, reporting warnings, and errors), but also accept interactive shell commands.

SciTE works on Windows and Linux, and it also has a commercial port on MacOS.

Lexers providing folding and syntax highlighting are based on code, not on regular expressions. They support context, nesting, special rules, etc.

SciTE is written in C++, with lot of contributors, both to the core and to the numerous lexers.

Has a simple graphical user interface

ReSharper is a popular Visual Studio Extension for .NET Developers. IntelliJ IDEA is a popular and fully featured JAVA IDE.

Extremely good at filling in all the mindless boilerplate type code while you stay productive.

Rider has everything you want from a serious IDE, but without the bloat. This results in significantly fast performance in day to day operations.

Project Rider supports the .NET Framework and Mono, with CoreCLR support in the works. It also includes templates for creating new projects, and when you create an empty project, it's literally empty

As well as running and debugging multiple runtimes, Project Rider itself runs on multiple platforms. It runs on Windows, Mac OS X, and Linux.

Intellij plugins for Git, Mercurial, and TFS plus Local History of files.

Project Rider can build MSBuild and XBuild solutions as well as DNX/.NET CLI projects, and allows debugging .NET and Mono applications. DNX/.NET CLI debugging and CoreCLR support are coming.

With a university email, Rider can be obtained for free.
