sled is a simple text editor with a terminal UI.
- Q: Why?
Because newcomers don't find vi(m) comfortable. Something akin to
EDIT.COMis usually perceived as more familiar: type text straight away,
C-Sto save, then
C-Q. (Sled still has vim‑like behavior, but it is “reverse” - default is insert mode, from which you can enter command mode.)
Because nano/joe are still relatively complicated.
As an exercise in programming in C, and to create an editor to my own liking, closer to suckless principles.
- Q: Why can't sled open the file “read only” even if modification is disallowed?
A: A text editor's purpose should be to edit text files. For just viewing text files, there's less(1). This avoids the situation when opening a file one is not allowed to write to with an editor like vi(1), only to have write operation denied after making numerous edits.
Of course, one could argue that screen editors like vi already double as text file viewers, but I think of displaying the contents of a writable file as being separate from displaying the contents of a non-writable file.
If this bothers you, you can use something like the included shell script sledv.
- Q: Is editing multiple files planned?
A: No, and this is by design. You can edit multiple files at the same time by running multiple instances of sled. You can arrange them on screen through a terminal multiplexer like GNU screen(1) or tmux(1), or just open several terminal emulators like st(1) and have your window manager arrange their windows. Inter-process “clipboard” can be managed by a terminal multiplexer or X.Org itself.
- Q: Is there a ~/.config/sled/config or ~/.sledrc?
A: No, and never will be. sled is intended to be configured through editing config.h and recompilation, like suckless software.
- Q: Are plugins planned?
A: No. Like suckless software, sled is meant to be extended through patches.
- Q: Why doesn't sled have feature X from text editor Y?
A: Most likely because it is not essential to editing text files. However, you are free to offer a patch supporting the feature, which will be included in the repository, with credits to the author.
- Q: How can I configure sled if I installed it (from AUR|through my distro's package manager)?
A: You don't. If you want customization/configuration, clone the git repo, customize and compile it from source, just like with suckless software.
- Q: Why am I getting a “Permission denied” when trying to edit a file?
A: You either can't access the directory for writing (and haven't disabled the creation of backups nor set
BACKUP_FAIL_OK), or the file itself.
C compiler - defaults in config.redo

$ git clone https://git.sr.ht/~strahinja/sled $ cd sled $ su
If you have djb redo:
# redo install
if you don't:
# ./do install
Persistent build configuration file
The file config.redo will be sourced when building targets which also accept
configuration through environment variables. For example,

Replace gcc in

$ <aur_helper> -S sled
To apply any patches, change the current directory to the one holding the sled repository, then:
$ git am path_to_patch/filename-of-patch.patch
and then call redo as above. Included patches are located inside the
