+ ed – line-oriented text editor
+ THIS IS CURRENTLY UNFINISHED! There are currently some minor noncompliant
+ parts (namely default addresses for commands), but there is currently no
+ regexes and no marks implemented. Basically all of the stuff that makes
+ ed actually useful are totally missing. You can still try it out I guess
+ though.
+ ed(1) is the standard UNIX text editor. While that is used a joke, ed is
+ legitimately a useful editor in the modern day, particularly when:
+ 1. Making a quick edit in a file you're familiar with
+ 2. Working over slow connections (low-baud serial, SSH on a shaky
+ hotspot, etc.)
+ 3. Programmatically editing files using the same commands you use to
+ edit. Just make one edit manually, put those commands in a script,
+ and run it on the rest of the files without having to convert the
+ actions into a different scripting language like awk
+ This is a reimplementation that's more compliant with other ed
+ implementations and the POSIX standard than GNU's implementation of ed:
+ https://www.gnu.org/software/ed/, while still having some of GNU ed's
+ convenience and extensions that are missing from those other ed
+ implementations. It'll also be implemented more simply than GNU ed, and
+ should have more clear and concise code (hopefully).
+ • POSIX or POSIX-compatible sh(1), for the configure script.
+ • Pure POSIX make(1). Most make's should support the POSIX standard.
+ • C compiler supporting C11. C99 is also supported as long as
+ stdnoreturn.h and anonymous structs and enums are supported as
+ extensions.
+ • VT100-compatible terminal, as linenoise(3) currently only supports
+ VT100 termal sequences (only very basic escape sequences required).
+ If you don't know if your terminal supports VT100 escape sequences,
+ then it does.
