base-cli
Plugin for base-methods that maps built-in methods to CLI args (also supports methods from a few plugins, like 'base-store', 'base-options' and 'base-data'.
You might also be interested in base-config.
TOC
Install
Install with npm:
$ npm install base-cli --save
Adds a cli
method to base
for mapping parsed command line arguments existing base methods or custom functions.
The goal is to simplify the process of settings up command line logic for your base application.
Usage
var cli = require('base-cli');
var Base = require('base');
var app = new Base();
app.use(cli());
API
This adds a cli
object to base with the following (chainable) methods (base.cli.*
):
.map()
- .map: add mappings from command line flags/options to custom functions or base
methods.alias()
- .alias: similar to map
but creates simple aliases. For example, alias('show', 'get')
would invoke the .get()
method when --show
is passed on the command line.process()
- .process: once all mappings are defined, pass argv
to .process()
to iterate over the mappings, passing argv
as context.
Example
var argv = require('minimist')(process.argv.slice(2));
var expand = require('expand-args');
var cli = require('base-cli');
var Base = require('base');
var app = new Base();
app.use(cli());
app.cli
.map('get', function(key, val) {
app.get(key, val);
})
.map('set', function(key, val) {
app.set(key, val);
})
app.cli.process(expand(argv), function(err) {
if (err) throw err;
});
CLI
Force questions that match the given pattern to be asked. The resulting answer data is merged onto app.cache.data
.
After questions are answered:
- Use
app.data('answers')
to get answer data. - To open the directory where data is persisted, enter
--open answers
in the command line
Example
$ --ask
$ --ask 'author.*'
$ --ask '*.name*'
Prefix the --config
flag onto other command line options to persist the value to package.json for the current project. For example, if you're using verb
, the value would be saved to the verb
object.
Params
Example
$ --config
$ --config=toc
$ --config=cwd:foo
$ --config=tasks:readme
Set the current working directory.
Example
$ --cwd=foo
$ --cwd
Set data on the app.cache.data
object. This is the API-equivalent of calling app.data()
.
Example
$ --data
$ --data=foo
$ --data=foo:bar
$ --data=foo.bar:baz
Bind console.error
to the given event listener, so that when event name
is emitted, the event arguments will be output in the console.
Example
$ --emit error
$ --emit view
$ --emit page
Persist a value to the global config store by prefixing a command line option with -g
or --global
.
Params
Example
$ -g=toc
$ -g=cwd:foo
$ -g=tasks:readme
Ask initialization questions and persist answer data to the global config store.
Example
$ --init
Open a directory, or open a file in the default application associated with the file type.
Example
$ --open answers
$ --open store
Set options on the app.options
object. This is the API-equivalent of calling app.option()
. You may also use the plural --options
flag for identical behavior.
Example
$ --option=foo
$ --option=foo:bar
$ --option=foo.bar:baz
Set in-memory options on the app.options
object. This is the API-equivalent of calling app.option()
. You may also use the singular --option
flag for identical behavior.
To display currently defined options, pass the --options
flag with no value.
Example
$ --options=foo
$ --options=foo:bar
$ --options=foo.bar:baz
Persist a value to the global config store by prefixing a command line option with --save
or -s
.
Params
Example
$ --save=toc
$ --save=cwd:foo
$ --save=tasks:readme
Alias for --tasks
. Run the given generators and tasks. This flag is unnecessary when used with base-runner.
Example
$ app --task foo
$ app --task foo:bar
Run the given generators and tasks. This flag is unnecessary when used with base-runner.
Example
$ app --tasks foo
$ app --tasks foo:bar
Returns true if val
is true or is an object with show: true
Params
val
{String}returns
{Boolean}
Config
Persist a value to the global config store by prefixing a command line option
with --save
flag is prefixed to other command line options when you want
to persist the value to the global config store. For example, let's say
you're running verb:
verb --cwd=foo
sets foo
as the cwd in memory, and would need to be set again the next time you run the verb
command.verb --save=cwd:foo
persists foo
to verb's [global config store][store] so that it's used as the default cwd each time you run the application.verb --config=cwd:foo
persists foo
to the verb
[config object][config] in package.json
to the global config store located in the user's home directory (for example, if you're running verb, the store would be located in ~/verb/verb.json
on mac), and would be .
