changing modes

In every mode esc switches to the next 'level' mode. The order is:

navigation < normal < insert

Exception to this order is the command mode. Leaving this mode will restore the previous one.

When transition from normal to navigation all changes to the filesystem will get persisted. Thus, changes in insert and normal are handled like unsaved buffer changes and are not present on the file system till :w gets called or the mode changes to navigation.

navigation mode

In navigation mode, all register interactions target the junk yard. The file register holds all files which got yanked and the last nine trashes.

keys action
gh goto home directory
gn go into normal mode
h, l navigating the file tree
p paste " from junk yard to current path
"p<char> paste register named <char> from junk yard to current path
yp copy current selected path to system clipboard
yy yank file to junk yard

navigation and normal mode

keys action
j, k navigating the current directory down/up
o, O add a new line and change to insert mode
I, A jump to line start/end and change to insert mode
dd go into normal and trash* the current line
: change to command mode
/ change to search downward
? change to search upward
n, N repeat last search in same/reverse direction
<space> add or remove (toggle) current file to quick fix list
q<char> start recording a macro on register <char>. Only letters [a-zA-Z] are allowed!
q while recording a macro, q finishes the recording and writes the input to the specified register.
@<char> replay a recorded macro on register <char>
@@ replay the last played macro
m<char> set mark for current selection. Only letters [a-zA-Z] are allowed!
'<char> jump to mark
zt, zz, zb move viewport to start, center, bottom of cursor position
C-u, C-d move viewport half screen up/down

*trash: files are not deleted but moved to yeets cache folder to enable junk yard interactions. Trashes get executed when leaving normal to navigation or saving the current buffer. To delete the selected path completly, call command :d!.

normal mode

In normal mode, all register interactions target the default register (equal to :reg in nvim).

keys action
h, l move cursor left/right
0, $ move cursor to line start/end
f<char>, F<char> move cursor to next char forward/backward
t<char>, T<char> move cursor before next char forward/backward
; repeat the last motion with f or t.
, repeat the last motion with f or t in reverse direction.
i, a change to insert mode
c<motion> delete according to motion and change to insert mode
d<motion> delete according to motion
s delete char on cursor and change to insert mode
x delete char on cursor
. repeat last modification. Key sequence is stored in '.' register

commands

: action
cfirst navigates to first entry in quick fix list
cl list all quick fix entries and highlights the current path
clearcl clears the selection for quick fix list in current folder only
cn, cN navigates to next/previous path in quick fix list
cdo <command> navigates to each entry in the quick fix list and executes the given command.
Cdo starts with the first entry and iterates over the given order. Thus, the list order is important! Non existing paths get ignored.
cp <path> or '<mark> copies the selected file to the target directory. The directory must exist without a file with the same name like the source
d! delete selected file/directory
mv <path> or '<mark> moves the selected file to the target. The directory must exist without a file with the same name like the source
delm <chars> delete current and cached marks. Every char represents one mark. ':delm AdfR', ':delm a d f R', and ':delm F' are all valid commands. Whitespaces are ignored.
e! reload current folder
invertcl inverts the cl selection in current folder
junk list junk yard contents
marks list all given marks
noh remove search highlights
q quit yeet
reg print all register entries
resetcl clears the current quick fix list without creating a new one
w write changes without changing mode
wq write changes and quit yeet

faq

how fast is yeet

It utilizes the same mechanics like yazi (tokio i/o) without that many roundtrips because of the underlying architecture. Thus, it should be equally fast. E.g. reading a directory with 500k entries takes only a couple of seconds without blocking the ui.

opening files in linux does nothing

yeet utilizes xdg-open to start files. Thus, not opening anything probably lies in a misconfigured mime setup. Check ~/.local/share/applications/ for invalid entries. Some programs causing problems regularly. Im looking at you wine...

architecture overview

yeet crate

The main crate is handling frontend and backend and resolves cli arguments to pass them to the relevant components.

yeet-frontend crate

The frontend follows an elm architecture with one exception: The model is mutable and will not get created every update.

It holds the lifecycle of the tui. It starts an event stream to enable non lockable operations. This stream is implemented in event.rs and translates multiple event emitter like terminal interaction with crossterm into messages.

The modules model, update and view represent parts of the elm philosophy. Messages are defined in yeet-keymap to prevent cycling dependencies.

yeet-buffer crate

Buffer holds all buffer relevant functionality to render content in yeet. Except e.g. Statusline, everything is a buffer!

The create follows the elm architecture as well.

yeet-keymap crate

This crate holds all key relevant features. The MessageResolver uses buffer and tree to resolve possible messages, which follow the elm architecture to modify the model.

tree uses the keymap to build a key tree structure. Thus, in keymap all key combinations are mapped indirectly to messages.

conversion translates crossterm key events to the yeet-keymap representation.
