Description:

rost 0.1.0

rost
A simple static site generator based on Jinja2 with a command line interface build using Click.
Installation
Use the following command to install rost:
$ python3 -m pip install rost

Living on the edge
If you want to work with the latest code before it’s released, install or update the code from the main branch:
$ python3 -m pip install -U git+https://github.com/Robert-96/rost.git

Quickstart
If you’re just looking to render simple data-less templates, you can get up and running with the command line:
$ rost build

This will recursively search ./templates for templates (any file whose name does not start with . or _) and build them to ./dist.
To monitor your source directory for changes, recompile files if they change, and start a webserver use watch:
$ rost watch

The build and watch each take these common options:

--searchpath: Sets the directory to look in for templates.
--outputpath: Sets the directory to place rendered files in.
--staticpath (is accepted multiple times): The directory (or directories) within searchpath where static files (such as CSS and JavaScript) are stored.

Getting help on version, available commands, arguments or option names:
$ rost --version
$ rost --help
$ rost build --help
$ rost watch --help

Advanced Usage
This part of the documentation covers some of rost’s more advanced features.
Using Custom Build Scripts
The command line shortcut is convenient, but sometimes your project needs something different than the defaults. To change them, you can use a build script.
A minimal build script looks something like this:
# build.py

from rost import build

if __name__ == "__main__":
build(
searchpath="templates",
outputpath="dist",
staticpaths=["static"]
)

Finally, just save the script as build.py (or something similar) and run it with your Python3 interpreter.
$ python3 build.py

Loading Data
The simplest way to supply data to the template is to pass a mapping from variable names to their values (a “context”) as the context keyword argument to the build or watch functions.
# build.py

from rost import build

# A context that should be available all the time to all templates.
context = {
"title": "Rost Example"
}

if __name__ == "__main__":
build(
searchpath="templates",
outputpath="dist",
staticpaths=["static"],
context=context
)

If you want to pass data to a specific template you can use the contexts keyword argument off the build and watch functions.
# build.py

from rost import build

# A context that should be available all the time to all templates.
context = {
"title": "Rost Example"
}

# A list of "regex, context" pairs. Each context is either a dictionary or a
# function that takes either no argument or or the current template as its sole
# argument and returns a dictionary. The regex, if matched against a filename,
# will cause the context to be used.
contexts = [
("*.html", {}),
]

if __name__ == "__main__":
build(
searchpath="templates",
outputpath="dist",
staticpaths=["static"],
context=context,
contexts=contexts
)

Custom Filters
Inside the templates variables can be modified by filters. All the standard Jinja2 filters are supported (you can found the full list here). To add your own filters, simply pass your as the filters keyword argument to the build and watch functions.
# build.py

from rost import build

filters = {
"hello": lambda x: "Hello, {}!".format(x)
}

if __name__ == "__main__":
build(
searchpath="templates",
outputpath="dist",
staticpaths=["static"],
filters=filters
)

Then you can use them in your template as you would expect:
{{ 'World'|hello }}
