Question

I’m looking for an editor/IDE that can provide features that are nice to have while coding (example: being able to click-through to function definitions) for languages that it is not specifically built for. By these, I have in mind languages designed for a very specific purpose and often only used by a small community. In other words, ones that would not have native support in most software.

I realize this would require a fair bit of fairy dust but I don’t think it’s out of the scope of what’s possible. Basically, the editor would have to be smart enough to recognize the commonly used syntax and semantics that many declarative languages have in common. It’s quite possible this would require some amount of configuration.

Does something like this exist? If not, what challenges do you think there would be in creating it?

Answer 1

If you need only the feature to jump of to the definition of a specific function or class, then VIM (and many other editors, like Emacs, Epsilon and JOE) can read the jump location from the ctags file. You just have to write a ctags file generator for your custom language.

For programmable editors (like VIM, Emacs, Epsilon, Eclipse and gedit), you can write your own plugin for your custom language, but it may quickly become time-consuming and a maintenance nightmare, because new versions of editors tend to change the plugin interface.

Please note that adding support for syntax highlighting is usually much easier than adding ctags-like support for symbol lookups. More advanced features, like refactoring and context-sensitive symbol completion (like Ctrl-Space and Tab in modern IDEs) are even harder to implement.
