This is to make room for a reasonable looking cargo plugin example. I got lazy and didn't update the tutorials.

Example of a busybox-style multicall program
|
|
|
|
See the documentation for clap::AppSettings::Multicall for rationale.
|
|
|
|
This example omits every command except true and false,
|
|
which are the most trivial to implement,
|
|
```bash
|
|
$ busybox true
|
|
? 0
|
|
$ busybox false
|
|
? 1
|
|
```
|
|
*Note: without the links setup, we can't demonstrate the multicall behavior*
|
|
|
|
But includes the `--install` option as an example of why it can be useful
|
|
for the main program to take arguments that aren't applet subcommands.
|
|
```bash
|
|
$ busybox --install
|
|
? failed
|
|
...
|
|
```
|
|
|
|
Though users must pass something:
|
|
```bash
|
|
$ busybox
|
|
? failed
|
|
busybox
|
|
|
|
USAGE:
|
|
busybox [OPTIONS] [APPLET]
|
|
|
|
OPTIONS:
|
|
-h, --help Print help information
|
|
--install <install> Install hardlinks for all subcommands in path
|
|
|
|
APPLETS:
|
|
false does nothing unsuccessfully
|
|
help Print this message or the help of the given subcommand(s)
|
|
true does nothing successfully
|
|
```
