xontrib-onepath 0.4.0
Associate files with app or alias and run it without preceding commands in xonsh shell.
License: BSD
Requires Python: >=3.6

<p align="center">
When you click to a file or folder in graphical OS they will be opened in associated app. The xontrib-onepath brings the same logic to the <a href="https://github.com/xonsh/xonsh/">xonsh shell</a>. Type the filename or path without preceding command and an associated action will be executed. The actions are customizable.

## Install
```bash
xpip install -U xontrib-onepath
echo 'xontrib load onepath' >> ~/.xonshrc
# Reload xonsh
```

## Examples
```bash
# Run:                 # Action that will be executed:                       
/                      # cd /
executable_script      # ./executable_script
.xonshrc               # vim ~/.xonshrc
~/Downloads/logo.png   # xdg-open ~/Downloads/logo.png
git                    # git
./git                  # cd ./git
```

## Default actions
If typed command is a registered name (i.e. `git`) and `which` command returns the path (i.e. `/usr/bin/git`) it will be executed. 
In other case the typed path will be used to make action. Default actions: 

| Priority | Type  | Action  |
|---|---|---|
| 1 | `<DIR>`  | `cd`  | 
| 2 | `<XFILE>`  | `<RUN>`  | 
| 3 | `text/` | `vim`|
| 4 | `image/` | `xdg-open` |

#### Help to add more types and best default actions. PRs are welcome!

You can add platform and tool depend actions:

```xsh
import shutil as _shutil
from xonsh.platform import ON_LINUX #, ON_DARWIN, ON_WINDOWS, ON_WSL, IN_APPIMAGE, ON_CYGWIN, ON_MSYS, ON_POSIX, ON_FREEBSD, ON_DRAGONFLY, ON_NETBSD, ON_OPENBSD

xontrib load onepath

if ON_LINUX and _shutil.which('nvim'):
    $XONTRIB_ONEPATH_ACTIONS['text/'] = 'nvim'
```

## File types

| # | Type    | Example  |
|---|---------|----------|
| 1 | Full path to file.                | `~/.xonshrc`     |
| 2 | File name.                        | `file.txt`        | 
| 3 | File extension.                   | `*.txt`           |
| 4 | MIME type/subtype and extension.  | `text/plain.txt`  |
| 5 | MIME type/subtype.                | `text/plain`      |
| 6 | MIME type.                        | `text/`           |
| 7 | Any file.                         | `<FILE>` (constant) |
| 8 | Any executable file.              | `<XFILE>` (constant)|
| 9 | Any directory.                    | `<DIR>` (constant)  |
| 10| Any file or directory.            | `*` (constant)    |

To get MIME type for the file run `file --mime-type --brief <file>`.

## Examples of actions

Use `XONTRIB_ONEPATH_ACTIONS` environment variable to add new actions.
If you need more complex actions use [callable xonsh aliases](https://xon.sh/tutorial.html#callable-aliases).

### Simple actions
```python
$XONTRIB_ONEPATH_ACTIONS['.xonshrc'] = 'vim'         # vim for `.xonshrc` file
$XONTRIB_ONEPATH_ACTIONS['*.log'] = 'tail'           # tail for text type *.log files
$XONTRIB_ONEPATH_ACTIONS['text/plain.txt'] = 'less'  # less for plain text *.txt files 
$XONTRIB_ONEPATH_ACTIONS['<DIR>'] = 'ls'             # list the files in the directory
$XONTRIB_ONEPATH_ACTIONS['application/zip'] = 'als'  # list files in zip file using atool
```

#### Run xsh regardless the execution permissions

```python
$XONTRIB_ONEPATH_ACTIONS = {'*.xsh':'xonsh', **$XONTRIB_ONEPATH_ACTIONS}  # Insert on top
xontrib load onepath
script.xsh                            # the same as:  chmod +x script.xsh && ./script.xsh
```

#### View CSV tables using pandas
```python
import pandas as pd
def _view_csv_with_pandas(args):
    print(pd.read_csv(args[0]))

aliases['view_csv_with_pandas'] = _view_csv_with_pandas
del _view_csv_with_pandas

$XONTRIB_ONEPATH_ACTIONS['application/csv'] = 'view_csv_with_pandas'
```

#### cd & ls
```python
def _cdls(args):
     cd @(args[0])
     if int($(ls | wc -l).strip()) < 100:
         ls --group-directories-first -a --color
aliases['cdls'] = _cdls
del _cdls

$XONTRIB_ONEPATH_ACTIONS['<DIR>'] = 'cdls'
```

## Known issues

### ImportError: failed to find libmagic

Install libmagic: `brew install libmagic`.

### NTFS in Linux: all files have execute permission
If you mount NTFS partition with default permissions then all files will have execute permission 
and `onepath` will execute them instead of action. The right way 
is to [change default `/etc/fstab` settings](https://askubuntu.com/questions/113733/how-do-i-correctly-mount-a-ntfs-partition-in-etc-fstab).
Example:
```bash
sudo umount /d
sudo mount -o uid=1000,gid=1000,dmask=027,fmask=137 /d 
ls -la /d
```
