A reusable project generator that _copies file recursively_, while
replacing keywords from passed data.
```js
'use strict'
const generify = require('generify')
const source = './template'
const dest = '/tmp/generify-test'
const data = { hello: 'hello world' }
// without notification
generify(source, dest, data, function (err) {
if (err) {
console.log(err)
} else {
console.log('ok!')
}
})
// with notification
generify(source, dest, data, onData, done)
function onData (file) {
console.log('writing file')
}
function done (err) {
if (err) {
console.log(err)
} else {
console.log('ok!')
}
}
```
This will replace all the `__hello__` patterns found in all files
with the `'hello world'` string.
If the supplied `data` has a key `transforms`, with a hash of tranformation
functions, then the found tokens will be used to run a corresponding
transform on the supplied data. Example:
```js
const data = {
transforms: { foo: (data, context) => data.toUpperCase() },
foo: 'foo'
}
// __foo__ => foo_transform(data = 'foo') => 'FOO'
```
The `context` object contains properties: `source` (input file path),
`dest` (output file path), `key` (the matched key).
files and directories located in the template folder may also be replaced. File and folder names wrapped with `@` delimiters will be replaced.
Given a template with:
`/template/@foo@/@bar@.txt`
and data:
```js
const data = {
foo: 'hello',
bar: 'world'
}
```
The outputted file will be:
`<dest>/hello/world.txt`
If a file begins with `__` that will be automatically converted into a
`.`. This is useful for generating `.gitignore` files.
If the supplied `data` has a key `copyAsNamed`, with an array of names, then
the filenames in that list will not be processed through this rule. Each file
name in the list should not include a path,
e.g. `['__do-not-replace-underscores.js']`.
__generify__ also offers an executable that can be called with:
Usage: generify template destination [json file]
Where the json file contains the data to be replaced.
