### Options

#### tend

Running `tend` with no cli arguments will try to load your `.tendrc` file and start from any configuration set in that

#### tend <action>

`tend` will try to load your `.tendrc` file and run the command provided in the section `<action>`. It will run the command
once and will not watch for changes in `directory`.

#### tend [--restart] [--start] [--ignoreHidden] [--filter <filter>] [<dir> <command>]

Run `tend` with options for a single directory/command from cli rather than loading options from `.tendrc`.

#### tend (--help | --version)

Show help/version information about `tend`

### .tendrc

`tend` can accept it's configuration from a `.tendrc` file rather than taking arguments from
the command line. Using `.tendrc` also allows you to run multiple instances of `tend` at once.

`.tendrc` files are parsed using [rc](https://github.com/dominictarr/rc).

```ini
; global settings
ignoreHidden=true

[js]
directory=./src
command=uglifyjs -o ./build/main.min.js ./src/*.js

[app]
directory=./app
command=node ./app/server.js
restart=true
start=true
```

The above config will run two instances of `tend`:
```bash
tend --ignoreHidden ./src "uglifyjs -o ./build/main.min.js ./src/*.js"
# AND
tend --ignoreHidden --restart ./app "node ./app/server.js"
```

#### .tendrc Options
* `ignoreHidden` - ignore hidden folders
* `restart` - restart `command` if a file changes while the previous is still running
* `start` - start `command` when `tend` starts
* `directory` - the directory to watch for changes
* `filter` - regular expression filter for filenames which will trigger `command`
* `command` - the command to run when a file has changed
