BB Key Bindings
|
|
|
|
User-defined key bindings go in config.h, which is created by running `make`
|
|
(config.def.h is for keeping the defaults around, just in case)
|
|
|
|
The basic structure is:
|
|
<list of keys to bind>
|
|
<program to run>
|
|
<description> (for the help menu)
|
|
<flags> (whether to run in a full terminal window or silently, etc.)
|
|
|
|
When the scripts are run, the following values are provided as environment variables:
|
|
|
|
$@ (the list of arguments): the full paths of the selected files
|
|
$BBCURSOR: the full name of the file under the cursor
|
|
$BB_DEPTH: the number of `bb` instances deep (in case you want to run a
|
|
shell and have that shell print something special in the prompt)
|
|
$BBCMD: a file to which `bb` commands can be written (used internally)
|
|
|
|
In order to modify bb's internal state, you can call `bb +cmd`, where "cmd"
|
|
is one of the following commands (or a unique prefix of one):
|
|
|
|
.:[01] Whether to show "." in each directory
|
|
..:[01] Whether to show ".." in each directory
|
|
cd:<path> Navigate to <path>
|
|
columns:<columns> Change which columns are visible, and in what order
|
|
deselect:<filename> Deselect <filename>
|
|
dotfiles:[01] Whether dotfiles are visible
|
|
goto:<filename> Move the cursor to <filename> (changing directory if needed)
|
|
interleave:[01] Whether or not directories should be interleaved with files in the display
|
|
jump:<key> Jump to the mark associated with <key>
|
|
mark:<key>[=<path>] Associate <key> with <path> (or current dir, if blank)
|
|
move:<num*> Move the cursor a numeric amount
|
|
quit Quit bb
|
|
refresh Refresh the file listing
|
|
scroll:<num*> Scroll the view a numeric amount
|
|
select:<filename> Select <filename>
|
|
sort:([+-]method)+ List of sortings (if equal on one, move to the next)
|
|
spread:<num*> Spread the selection state at the cursor
|
|
toggle:<filename> Toggle the selection status of <filename>
|
|
|
|
Internally, bb will write the commands (NUL terminated) to $BBCMD, if
|
|
$BBCMD is set, and read the file when file browsing resumes. These commands
|
|
can also be passed to bb at startup, and will run immediately.
|
|
E.g. `bb +col:n +sort:r .` will launch `bb` only showing the name column, randomly sorted.
|
|
|
|
*Note: for numeric-based commands (like scroll), the number can be either
|
|
an absolute value or a relative value (starting with '+' or '-'), and/or
|
|
a percent (ending with '%'). Scrolling and moving, '%' means percent of
|
|
screen height, and '%n' means percent of number of files (e.g. +50% means
|
|
half a screen height down, and 100%n means the last file)
