diecutter 0.2

Install

Install diecutter from Github, configure it then run the server:

# Download and install (in a virtualenv if you like).
pip install -e git+git@github.com:novagile/diecutter.git#egg=diecutter
# Configure: adapt "YOUR_TEMPLATE_DIR"!
wget -O diecutter.ini --post-data "template_dir=YOUR_TEMPLATE_DIR" http://diecutter.alwaysdata.net/diecutter.ini
# Run the server.
pserve diecutter.ini --reload

Check it works:

$ curl http://localhost:8106
{"diecutter": "Hello", "version": "0.1dev"}

Files

Put your template in the service templates directory or use the API:

$ echo "Hello {{ who }}" | curl -X PUT http://localhost:8106/hello -F "file=@-"
{"diecutter": "Ok"}

Then we can get the raw template we just created:

$ curl http://localhost:8106/hello
Hello {{ who }}

And we can render the template against some variables:

$ curl -X POST http://localhost:8106/hello -d 'who=world'
Hello world

Directories

You can also get directories:

$ echo "circus.ini" | curl -X PUT http://localhost:8106/circus/circus.ini -F "file=@-"
{"diecutter": "Ok"}

$ echo "circus_django.ini" | curl -X PUT http://localhost:8106/circus/circus_django.ini -F "file=@-"
{"diecutter": "Ok"}

$ curl http://localhost:8106/circus
circus/circus.ini
circus/circus_django.ini

$ curl http://localhost:8106/circus/
circus.ini
circus_django.ini

If you want to render the directory against a global context:

$ curl -X POST http://localhost:8106/circus
/-- Get a ZIP archive with all the files listed below rendered against the context --/

$ mkdir -p ~/sandbox/
$ cd ~/sandbox/
$ curl -X POST http://localhost:8106/circus > circus.zip
$ unzip circus.zip
$ tree .

│   ├── circus_django.ini

└── circus.zip

Posting input data

When you perform POST requests on resources, you provide a context, i.e. variables and values.

Diecutter has builtin support for the following input content-types:

• “application/x-www-form-urlencoded”: the default when you perform POST requests with wget or curl. See http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.1

• “application/json”: JSON encoded data. See http://json.org/.

• “text/plain”: INI-style plain text files. See https://en.wikipedia.org/wiki/INI_file and http://docs.python.org/2.7/library/configparser.html.

Diecutter expects data to be provided as the body of the request. “multipart/form-data” requests aren’t supported currently.

Here are “flat” examples using curl.

# All examples below return the same result.

# Default (implicit application/x-www-form-urlencoded content type).
curl -X POST -d 'who=world' http://localhost:8106/hello

# Explicit "application/x-www-form-urlencoded" content-type.
curl -X POST -d 'who=world' -H "Content-Type: application/x-www-form-urlencoded" http://localhost:8106/hello

# JSON.
curl -X POST -d '{"who": "world"}' -H "Content-Type: application/json" http://localhost:8106/hello

# INI.
curl -X POST -d 'who=world' -H "Content-Type: text/plain" http://localhost:8106/hello

INI content-type allows you to provide 2 levels of data:

cat > input.ini <<EOF
hello = world
[foo]
bar = baz
EOF
curl -X POST --data-binary '@input.ini' -H "Content-Type: text/plain" http://localhost:8106/hello
# Templates can use variables like {{ hello }} and {{ foo.bar }}.

JSON allows you to provide multiple levels of data.

Render file names

Sometimes you want to define names from the context.

You just add to put +context_name+ it will match automatically:

 $ echo "[watcher:{{ watcher_name }}]" | curl -X PUT http://localhost:8106/circus/circus_+watcher_name+.ini -F "file=@-"
 {"diecutter": "Ok"}

 $ curl http://localhost:8106/circus
 circus/circus.ini
 circus/circus_django.ini
 circus/circus_+watcher_name+.ini

$ curl http://localhost:8106/circus -d 'watcher_name=diecutter' > circus.zip
$ unzip -l circus.zip
Archive:  circus.zip
  Length      Date    Time    Name

A full example : the diecutter django_admin.py startproject

As an example, we added a +django_project+ template that you can use like this:

$ curl http://localhost:8106/+django_project+ -d 'django_project=diecutter_demo' > diecutter_demo.zip
$ unzip -l diecutter_demo.zip
