# 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 $HOME/.cargo/bin
|
||||||
|
```
|
||||||
|
|
||||||
|
## Implemented features
|
||||||
|
|
||||||
|
### Configuration
|
||||||
|
The configuration is loaded as follows
|
||||||
|
1. load values from `$XDG_CONFIG_HOME/twilight-tree.toml`
|
||||||
|
2. else load values from `$HOME/.config/twilight-tree/twilight-tree.toml`
|
||||||
|
2. fill missing values with app defaults
|
||||||
|
3. 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.reload=r`|collapse all directories and reload root directory|
|
||||||
|
|return|`--keybinding.file_action=return`|perform configured file action|
|
||||||
|
|q|`--keybinding.quit=q`|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`
