I think most of us have used any advanced code editor sometime, namely Atom, Sublime Text, VS Code, Brackets, ...

I personally love Atom, I have already mastered it and with that I have been dealing with its weak points: performance with big files is the biggest one IMO.

Browsing and researching I have found that most advanced code editors (named in the first paragraph) are web-based, programmed in HTML, CSS and JavaScript (or variants of this one, which are almost the same).

Several people recommended me to take the step and move to EMACS or VIM. I really have no that amount of time to start learning these, and I am not really interested.

So the question is the title: Is there any advanced code editor that is programmed in a higher performance language (C++, Rust, ...), available for Windows, Linux or Mac with almost the same good features as the mentioned ones (open-source would be great)?

Thanks in advance.

  • I do not have a recommendation for you but maybe you can try timecop: atom.io/packages/timecop With this plugin you see where time is spent while Atom loads. This could help to identify slow packages.

  • Sublime is written in C++ and Python.

  • @SiXandSeven8ths Do not know, but Sublime is not free nor open source, is really buggy, and somehow not as fast as it should be opening large files. Jun 20, 2018 at 14:18
  • @Davdriver Fair enough, just pointing out that it was written in C++ and Python is all.

Instead of Sublime Text, try CudaText, it has some similar menuitems, and loading speed for huge files (100-800Mb) is faster than in ST. But rendering speed is slower than in ST.

It also has Python plugins for developers.


Maybe what you are looking for could be in the below:

  1. Eclipse
  2. IntelliJ IDEA

Great IDEs and very powerful. Eclipse in particular as it has tons of extensions to further focus on your line of development.

Hope this helped.

    The problem with IDEA and Eclipse is that both are resource-heavy, and I am looking for just an advanced code editor, not a full programming IDE. But thanks for your contribution anyway. Jun 19, 2018 at 11:01
  • I understand. Would it have to be cross-platform? As an example, Coda is a great editor for the Mac. Notepad++ is great for Windows. Lime Text is based on Go but is crossplatform. Wouldnt know if it handles large files though.

  • I love Notepad++, and there is no money for Mac stuff. But will check out Lime Text, seems promising. Jun 19, 2018 at 12:36
  • Lime Text is a try to make Sublime Text clone on Go. It is not done.
