# Rybak
_/ˈrɨ.bak/_
Directory-tree generator library.
## Synopsis
Rybak is an extension of template engines, which instead of rendering a single file or string, renders a whole
directory.
In a way it's similar to
[Cookiecutter](https://pypi.org/project/cookiecutter/) or
[Copier](https://pypi.org/project/copier/),
but while these programs are designed specifically for generating software projects scaffolding,
Rybak is a library for generating arbitrary directory tree structures.
Rybak template is a directory consisting of template files.
[Jinja](https://pypi.org/project/jinja2/), and
[Mako](https://pypi.org/project/mako/)
are supported, though one project can only use a single template engine.
Goals:
- [x] generate directory-tree based on a user-provided template and data,
- [x] keep track and remove files that aren't produced by the template,
- [x] allow for multiple files to be generated from a single template file,
- [ ] support but don't require templates to be git or other DCVS repositories.
Non-goals:
- command line interface,
- prompting users for template data.
## Usage
```python
from pathlib import Path
from rybak import TreeTemplate
from rybak.jinja import JinjaAdapter
from jinja2.loaders import FileSystemLoader
TreeTemplate(
JinjaAdapter(loader=FileSystemLoader('template_root')),
).render(
{'likes': {
'Alice': 'Bob',
'Bob': 'Charlie',
'Charlie': 'cats',
}},
Path('target_root'),
)
```
- `template_root`:
is the directory containing template files, in this case Jinja templates. Templates can be used in file content, file
names and directory names.
### Single template multiple data
Template files can be applied to collections of items.
In order to do so, a special function is made available, `loop_over` that iterates over a passed collection. The
function can only be used in templates in file names.
`loop_over` returns the element of the collection, so that it can be used to render name.
model:
```python
names = [
'Alice',
'Bob',
'Charlie',
]
```
file name:
`{{loop_over(names)}}`
would produce three files: Alice, Bob and Charlie.
The current item is also available during rendering the file contents, as model variable `item`.
Of course, we might want different value in the file name and its content. For that we can manipulate the `loop_over`s
result:
model:
```python
likes = {
'Alice': 'Bob',
'Bob': 'Charlie',
'Charlie': 'cats',
}
```
file name: `{{loop_over(likes.items())[0]}}`
file content: `{{item[1]}}`
`loop_over(likes.items())` produces a key-value tuple for each file, and `[0]` accesses the key.
Similarly, `{{items}}` would produce the same key-value pair, and [1] accesses the value.
Alternatively, the model could be a list of complex objects:
model:
```python
likes = [
{'name': 'Alice', 'likes': 'Bob'},
{'name': 'Bob', 'likes': 'Charlie'},
{'name': 'Charlie', 'likes': 'cats'},
]
```
In this case the file name template simplifies to `{{loop_over(likes).name}}` and the content template
to `{{item.likes}}`.
## Installation
Rybak templates can work with either of Jinja, Mako or Torado; so typically you need to install Rybak and one of those
libraries.
installing `rybak[jinja]` or `rybak[mako]` will handle this.
## Name
'y' is pronounced like in 'sit',
'a' like in 'father', just shorter.
Rybak is a Polish word for fisherman.
The original idea was to only support Mako templates, which is named by a species of a shark.
Functionality of this library is provided by the template engine, so picture a fisherman pulled by a shark.
