Emacs
Smartsheet for pc. Emacs is a very flexible and extensible editor that has been around for a long time. Due to its history and huge community, it is capable of covering pretty much any area of programming and more.
If you want to use Emacs on your home PC running Microsoft Windows, you can download it for free.Simply fetch the file with a name like emacs-25.1-2-i686-w64-mingw32.zip (the version number may change). Unzip the zip file preserving the directory structure, and run binrunemacs.exe.Alternatively, create a desktop shortcut to binrunemacs.exe, and start Emacs by double-clicking on that shortcut. I extensively use /usr/bin/emacs in Terminal. I have Emacs 22 and I'd like to upgrade it to 23. I wonder how to do it. Googling 'emacs download mac' gives me Emacs.app which has its own window and user interface, but I don't want that. I am not sure how I have /usr/bin/emacs in the first place, maybe it came with Mac.
Bundled with Emacs are some very useful packages, the major ones being Slime, Magit, and Company.
