This is a fork of twilight-commander

twilight-tree

A simple console tree file explorer for linux, similiar to NERDTree but independent of vim. Developed and tested on Ubuntu 18.04 with xterm derivatives.

Build and install

git clone https://git.4rs.nl/awiteb/twilight-tree
cd twilight-tree
cargo install --path . # this will install the binary in $HOME/.cargo/bin

twilight-tree vs twilight-commander

• With twilight-tree you can hide the header (Which is the current working directory) with --setup.with_cwd_header=false
• You can rename a file/directory using the r keybinding. To move a file/directory, specify the new path along with the new name. For example, ../new_name.rs will move the file to the parent directory and rename it to new_name.rs.
• You can delete a file/directory with ctrl+d keybinding
• You can create a new file with n+f keybinding
• You can create a new directory with n+d keybinding

Implemented features

Configuration

The configuration is loaded as follows

1. load values from $XDG_CONFIG_HOME/twilight-tree.toml
2. else load values from $HOME/.config/twilight-tree/twilight-tree.toml
3. fill missing values with app defaults
4. overwrite values with defines from the command line options

For a config file with the default values, see twilight-tree.toml. The command line options are derived from the values defined inside the twilight-tree.toml . E.g.

[debug]
enabled = true

is set with the option --debug.enabled=true.

Configurable key bindings

The key bindings are configurable. For the set of configurable keys and key combinations consult the event.rs.

default key	default configuration	action
up arrow	--keybinding.entry_up=up	move an entry up
down arrow	--keybinding.entry_down=down	move an entry down
left arrow	--keybinding.collapse_dir=left	collapse an entry directory or jump to parent if not collapsable
right arrow	--keybinding.expand_dir=left	expand an entry directory
r	--keybinding.rename_mode=r	Enter rename mode (To exit rename mode press quit keybinding)
n	--keybinding.new_entry=n	Enter create mode (To exit rename mode press quit keybinding)
ctrl+r	--keybinding.reload=r	collapse all directories and reload root directory
ctrl+d	--keybinding.remove=ctrl+d	remove a file/directory
return	--keybinding.file_action=return	perform configured file action
esc	--keybinding.quit=esc	quit

Directory entry management

File Action

The command line option / config value --behavior.file_action defines the action taken when the return key is pressed on a file. The action is interpreted by bash and any occurence of %s will be replaced by the selected filename.
E.g. when enter is pressed on the file .bashrc in a twilight-tree process created with

twilight-tree "--behavior.file_action=xterm -e 'cat %s; echo opened file: %s; bash'"

then

bash -c "xterm -e 'cat /home/user/.bashrc; echo opened file: /home/user/.bashrc; bash'"

is executed, i.e.:

• a new xterm window is opened
• where the selected file (.bashrc) is printed to stdout
• then opened file: ~/.bashrc is printed
• bash prevents the window from closing.

--behavior.file_action defaults to true, which does (almost) nothing.

Scrolling modes

Specified with the option --behaviour.scrolling (default = center)

• center: move the cursor until it is in the center, then move the text instead
• editor: move the cursor until it hits the top/bottom boundaries set by the debug.paddin_top/bot limits

Utf-8 support

In case your terminal does not support utf-8 you can disable it with --composition.use_utf8=false.

Logs

Logs are written to
