@hyrious/dev-cmd v0.1.2

dev-cmd

dev is a command-line tool that modifies commands before run.

npm i -g @hyrious/dev-cmd
dev --add proxy ... -c http.proxy=socks5://localhost:1080
# proxy = ... -c http.proxy=socks5://localhost:1080
dev proxy git clone XXX
# actually run: git clone XXX -c http.proxy=socks5://localhost:1080
dev --remove proxy
# removed proxy

The simplest example above just replaces ... with original command line, where it was git clone XXX.

Now let's add something more useful than that!

--add {cmd} {rule} / -A

Add/replace {cmd} with rule after it. If no rule presents, it does nothing.

dev -A hello echo "hello world!"
dev hello
=> hello world!

! Note: Windows users will encounter errors bacause echo is not a program but a shell command.

--starts-with {prefix} / =

Works only when original command starts with {prefix}. For example,

dev -A proxy = git ... -c http.proxy=socks5://localhost:1080

means that, only dev proxy git XXX will be modified by this rule.

Different {prefix} won't affect other rules imported by the same {cmd}, which means you can do this:

dev -A proxy ... --http-proxy=http://localhost:1080
dev -A proxy = git ... -c http.proxy=socks5://localhost:1080
dev -A proxy = aria2c ... --all-proxy=http://localhost:1080
dev -A proxy = scoop scoop config proxy http://localhost:1080 && ...

--remove {cmd} [--all] / -R

Remove {cmd}. It won't affect rules with {prefix} having the same {cmd}. To remove them too, add --all.

--starts-with {prefix} / =

Just like -A, remove specific {cmd} and {prefix}.

dev -R proxy
dev -R proxy = git
dev -R proxy --all

--plugin {path/to/plugin.js} [--save] / -P

You can add more complex rules with plugins. Here is an example.

module.exports = dev =>
  dev.add('proxy', {
      // you can use regex here, but keep in mind it only
      // matches the first argument, which is the command itself,
      // like `git`, `scoop`
      startsWith: 'scoop',
      run(cmd) {
          dev.sh('scoop', ['config', 'proxy', 'http://localhost:1080'])
          dev.sh(cmd)
      },
      remove() {
          dev.sh('scoop', ['config', 'rm', 'proxy'])
      }
  })

If --save presents, it will write this plugin's path into .dev.json's plugins list, see below.

--list / -L

Show rules.

.dev.json

dev will automatically load .dev.json at current & home folder.

{ "rules": [
    { "name": "proxy",
      "startsWith": "git",
      "run": ["...", "-c", "http.proxy=socks5://localhost:1080"]
    }
  ],
  "plugins": [
    "~/plugin.js"
  ]
}
