The primary script here is simple script for checking and cleaning the minor but annoying spaceless template tag and template variable brackets that find their way into Django templates. However it should work with template languages with similar syntax like Jinja (Python) or Liquid (Ruby).
The scripts are known to work in Ubuntu Linux but not on Mac OS X due to sed related errors.
These scripts perform very simple clean up to ensure that there is a space between opening and closing context variable brackets.
Annoying and hard to read:
{{myar}}
{%for object in object_list%}
Appease the gods:
{{ myar }}
{% for object in object_list %}
Basic usage:
./curly-spacing.sh
By default the script will search recursively starting from the current directory and limited to files with the "html" extension. If there are matches it will list them and return an exit code of 1. If there are no matches it will return an exit code of 0. This allows for it to be used by other scripts for automated codebase testing.
You can specify a starting directory with the d flag:
./curly-spacing.sh -d templates
And use the f flag to provide an alternate file extension to search.
./curly-spacing.sh -d templates -f htm
You can pass the e flag to edit the problems in place.
./curly-spacing.sh -d templates -f htm -e
When editing no attempt is made to control the exit code based on matches.
Changed in Django 1.5: The first parameter used not to be quoted, which was inconsistent with other template tags. Since Django 1.5, it is evaluated according to the usual rules: it can be a quoted string or a variable that will be looked up in the context.
From the Django docs
This script just adds single quotation marks around the URL name in each
instance of a url tag in your templates.
./django-url.sh
This script takes the same optional directory argument and file extension as the template tag cleaning script.
I have cobbled together these scripts based on other people's helpful examples [1], so anything in here that is my original work is hereby released into the public domain.
