Clip is a port of most of the featutty of Express to CLI programming.
Many times we want to have complex use cases that are hard to express and routing along Express and Sugarskull seem to be an apt way of doing this. Another thing that we want to do in CLI programming often is use configuration files, flags, and parameters.
Sharing routes between express and cli, since most often they should look the same Some basic things should be done for you. Configuration files.
Help for commands should always use the same flags.
You can make a repl by posting urls, not too hard. Most applications should not need internal repls.
Urls are partitioned with '/' with a starting '/' at all times, they are url encoded, and accept ':param' and '*'
Request follow the cmd,tty,next
methodology except with cmd,tty,next
since we are talking about command information, the terminal, and next stays the same.
In the future chaining CLI requests should be easier (ie a clean + build could be done through clip by calling the corresponding urls).
cmd.env = process.env
cmd.flags = require('optimist').argv
cmd.config = require('nconf') + app.config(...)
cmd.prompt = require('prompt')
cmd.params = app.cli(':param') ...
tty = require('winston') + require('cliff')
Determines where to find the config property for requests, uses reconf
Uses a middleware if a flag is set, uses optimist
Executes a handler if the path is matched
CLI parameter preconditions ala express
#!/usr/local/bin/node
var clip = require('../');
var app = new clip();
var version = '0.0.1';
//
// SETUP
//
// Recursively find an 'app.json' file with reconf and add it to cmd.config
app.config('app.json',{flags:['conf']});
// Dont print stuff to console if --silent is set
app.flag('silent',function(cmd,tty,next){
tty.remove(tty.transports.Console);
next();
});
// Always print out the app info (middleware)
app.use(function(cmd,tty,next){
tty.info('App.js '+version);
next();
});
app.usage(function(cmd,tty,next) {
tty.info('commands: helloworld, info');
});
app.cli(['/hello','/helloworld'], function(cmd,tty,next) {
tty.info('hello world!');
});
var utils = require('util');
app.cli(['/info','/dump'], function(cmd,tty,next) {
tty.data(utils.inspect(cmd));
});
app.run();
