Ranked in these QuestionsQuestion Ranking
Pros
Pro Well documented
A long and well written tutorial teaches how to program in femtolisp and write extensions for Femto Emacs.
Pro Highly compatible with Emacs
If you know Emacs, you can start using Femto Emacs immediately.
Pro Very small footprint
The size of the executable file and the femtolisp library add up to only 500 k. The C source code is also small and well documented, so one can easily modify it. You can also use the source code to learn how to program a text editor.
Pro Very fast startup time
For small files, Femto Emacs starts up faster than emacs or vim.
Pro Vim without a shell
When opening files from the file manager, it is still nice to have vim.
Pro Excellent performance
Because it loads the whole file into RAM, replacing all string occurences in 100MB+ files is quick and easy. Every other editor sort of died during that.
Pro Works on all platforms
Whether its your windows machine, a Linux, Unix or a Mac Vim would work everywhere. You can even build it from its source on your favorite linux environment.
Pro Has different cursor shape in command and insert modes
Unlike vim, gvim has different cursor shape in command and insert mode, which is very convenient.
Pro Supports all vim features and settings
All vim features, custom settings, and plugins are automatically available.
Cons
Con No syntax coloring for Latex
The distribution comes with syntax coloring examples for many languages, like Haskell, C, Lisp, Python, etc. However, there is no scheme for Latex. If you need syntax coloring for Latex, you will need to add your own color scheme.
Con Source distribution only
Femto Emacs is distributed only in source form. Therefore, you need to install ncurses, gcc and compile it with make and make install. There is no binary distribution. If you want mouse support, you need to program it in femtolisp or in C. This should not be a problem if you are a programmer, but can become an issue if you don't know Lisp or C. If you want to use femtolisp on Windows, you will need mingw and ncurses.
Con GVim, like Vim, has a difficult learning curve
A lot of time is needed to learn all the commands and modes supported. A lot of time will also be spent tuning all the settings to the user's preference.
