This plugin allows liquid-style tags to be inserted into markdown within
Pelican documents. Liquid uses tags bounded by {% ... %}
, and is used
to extend markdown in other blogging platforms such as octopress.
This set of extensions does not actually interface with liquid, but allows users to define their own liquid-style tags which will be inserted into the markdown preprocessor stream. There are several built-in tags, which can be added as follows.
First, in your pelicanconf.py file, add the plugins you want to use:
PLUGIN_PATH = '/path/to/pelican-plugins'
PLUGINS = ['liquid_tags.img', 'liquid_tags.video',
'liquid_tags.youtube', 'liquid_tags.vimeo',
'liquid_tags.include_code', 'liquid_tags.notebook']
There are several options available
To insert a sized and labeled image in your document, enable the
liquid_tags.img
plugin and use the following:
{% img [class name(s)] path/to/image [width [height]] [title text | "title text" ["alt text"]] %}
There is one more tag for image: b64img
. It is based on img
tag, but instead of inserting link on image it acutally reads image and inserts it as base64 text into <img src=
attribute.
To use it:
liquid_tags.b64img
{% b64img [class name(s)] path/to/image [width [height]] [title text | "title text" ["alt text"]] %}
Images are read on compilation phase so you can use any local path (just be sure that image will remain there on next compilation)
To insert a sized and labeled Instagram image in your document by its shortcode (such as pFI0CAIZna
), enable the liquid_tags.gram
plugin and use the following:
{% gram shortcode [size] [width] [class name(s)] [title text | "title text" ["alt text"]] %}
You can specify a size with t
, m
, or l
.
To insert a Flickr image to a post, follow these steps:
liquid_tags.flickr
Add this to your document:
{% flickr image_id [small|medium|large] ["alt text"|'alt text'] %}
To insert a gif from Giphy in your document by its id (such as aMSJFS6oFX0fC
), enable the liquid_tags.giphy
plugin and use the following:
{% giphy gif_id ["alt text"|'alt text'] %}
IMPORTANT: You have to request a production API key from giphy here. For the first runs you could also use the public beta key you can get here.
To insert a Soundcloud Widget to a post, follow these steps:
liquid_tags.soundcloud
Add this to your document:
{% soundcloud track_url %}
To insert youtube video into a post, enable the
liquid_tags.youtube
plugin, and add to your document:
{% youtube youtube_id [width] [height] %}
The width and height are in pixels, and can be optionally specified. If they are not, then the dimensions will be 640 (wide) by 390 (tall).
If you're experiencing issues with code generating (i.e. missing closing tags), add SUMMARY_MAX_LENGTH = None
to your config.
To insert a Vimeo video into a post, enable the
liquid_tags.vimeo
plugin, and add to your document:
{% vimeo vimeo_id [width] [height] %}
The width and height are in pixels, and can be optionally specified. If they are not, then the dimensions will be 640 (wide) by 390 (tall).
If you're experiencing issues with code generating (i.e. missing closing tags), add SUMMARY_MAX_LENGTH = None
to your config.
To insert flash/HTML5-friendly video into a post, enable the
liquid_tags.video
plugin, and add to your document:
{% video /url/to/video.mp4 [width] [height] [/path/to/poster.png] %}
The width and height are in pixels, and can be optionally specified. If they are not, then the original video size will be used. The poster is an image which is used as a preview of the video.
To use a video from file, make sure it's in a static directory and put in the appropriate url.
To insert HTML5 audio into a post, enable the liquid_tags.audio
plugin,
and add to your document:
{% audio url/to/audio [url/to/audio] [url/to/audio] %}
Up to 3 audio urls are possible. So you can add different versions of the audio file you want to post because not every browser support every file format.
To use a audio from file, make sure it's in a static directory and put in the appropriate url.
To include code from a file in your document with a link to the original
file, enable the liquid_tags.include_code
plugin, and add to your
document:
{% include_code /path/to/code.py [lang:python] [lines:X-Y] [:hidefilename:] [title] %}
All arguments are optional but their order must be kept. :hidefilename:
is
only allowed if a title is also given.
{% include_code /path/to/code.py lines:1-10 :hidefilename: Test Example %}
This example will show the first 10 lines of the file while hiding the actual filename.
The script must be in the code
subdirectory of your content folder:
this default location can be changed by specifying
CODE_DIR = 'code'
within your configuration file. Additionally, in order for the resulting hyperlink to work, this directory must be listed under the STATIC_PATHS setting, e.g.:
STATIC_PATHS = ['images', 'code']
To insert an IPython notebook into your post, enable the
liquid_tags.notebook
plugin and add to your document:
{% notebook filename.ipynb %}
The file should be specified relative to the notebooks
subdirectory of the
content directory. Optionally, this subdirectory can be specified in the
config file:
NOTEBOOK_DIR = 'notebooks'
Because the conversion and rendering of notebooks is rather involved, there are a few extra steps required for this plugin:
First, you will need to install IPython:
pip install ipython==2.4.1
After typing "make html" when using the notebook tag, a file called
_nb_header.html
will be produced in the main directory. The content
of the file should be included in the header of the theme. An easy way
to accomplish this is to add the following lines within the header template
of the theme you use:
{% if EXTRA_HEADER %} {{ EXTRA_HEADER }} {% endif %}
and in your configuration file, include the line:
EXTRA_HEADER = open('_nb_header.html').read().decode('utf-8')
this will insert the proper css formatting into your document.
The notebook tag also has two optional arguments: cells
and language
.
{% notebook filename.ipynb cells[2:8] %}
{% notebook filename.ipynb language[julia] %}
This may be helpful for those using IJulia
or notebooks in any other language, especially as the IPython project broadens its
scope of language
compatibility. By default, the language for highlighting
will be ipython
.
cells
must come before language
:{% notebook filename.ipynb cells[2:8] language[julia] %}
The plugin also enables collapsible code input boxes. For this to work
you first need to copy the file pelicanhtml_3.tpl
(for IPython
3.x, pelicanhtml_2.tpl
(for IPython 2.x)...) to the top level of your
Pelican blog. Notebook input cells containing the comment line #
<!-- collapse=True -->
will be collapsed when the html page is
loaded and can be expanded by clicking on them. Cells containing the
comment line # <!-- collapse=False -->
will be open on load but
can be collapsed by clicking on their header. Cells without collapse
comments are rendered as standard code input cells.
To test the plugin in multiple environments we use tox, to run the entire test suite, just type:
cd path/to/liquid_tags
