# 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

```sh
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](./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](./src/model/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](<https://en.wikipedia.org/wiki/True_and_false_(commands)>), 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

1. `$XDG_CONFIG_HOME/tc.log` if XDG_CONFIG_HOME is defined
2. else they are placed in `$HOME/.config/twilight-tree/tc.log`
