Landslide generates a slideshow using the slides that power the html5-slides presentation.
A sample slideshow is here.
- Write your slide contents easily using the Markdown or ReStructuredText syntaxes
- HTML5, Web based, stand-alone document (embedded local images), fancy transitions
- PDF export (using PrinceXML if available)
python
and the following modules:
jinja2
pygments
for code blocks syntax colorationmarkdown
if you use Markdown syntax for your slide contentsdocutils
if you use ReStructuredText syntax for your slide contents
textile
for textile support
The easiest way to install Landlside is probably using pip
:
$ pip install landslide
Alternatively, you can use easy_install
:
$ easy_install landslide
If you want to stay on the edge:
$ git clone https://github.com/adamzap/landslide.git
$ cd landslide
$ python setup.py build
$ sudo python setup.py install
- Your Markdown source files must be suffixed by
.md
,.markdn
,.mdown
or.markdown
- To create a title slide, render a single
h1
element (eg.# My Title
) - Separate your slides with a horizontal rule (
---
in markdown) except at the end of md files - Your other slides should have a heading that renders to an
h1
element - To highlight blocks of code, put !
{lang}
where{lang}
is the pygment supported language identifier as the first indented line
- Your ReST source files must be suffixed by
.rst
or.rest
(.txt
is not supported) - Use headings for slide titles
- Separate your slides using an horizontal rule (
----
in RST) except at the end of RST files
- Textile cannot generate
, so you must insert those manually to separate slides
- Run
landslide slides.md
orlandslide slides.rst
- Enjoy your newly generated
presentation.html
Or get it as a PDF document if PrinceXML is installed and available on your system:
$ landslide README.md -d readme.pdf
$ open readme.pdf
- Press

Several options are available using the command line:
-h, --help show this help message and exit
-c, --copy-theme Copy theme directory into current presentation source
directory
-b, --debug Will display any exception trace to stdin
-d FILE, --destination=FILE

-i, --embed Embed stylesheet and javascript contents,
base64-encoded images in presentation to make a
standalone document
-l LINENOS, --linenos=LINENOS
How to output linenos in source code. Three options
availables: no (no line numbers); inline (inside <pre>
tag); table (lines numbers in another cell, copy-paste
friendly)
-o, --direct-output Prints the generated HTML code to stdin; won't work
with PDF export
-q, --quiet Won't write anything to stdin (silent mode)
-r, --relative Make your presentation asset links relative to current
pwd; This may be useful if you intend to publish your
html presentation online.
-t THEME, --theme=THEME

-v, --verbose Write informational messages to stdin (enabled by
default)
-x EXTENSIONS, --extensions=EXTENSIONS
Comma-separated list of extensions for Markdown
Landslide allows to configure your presentation using a cfg
configuration file, therefore easing the aggregation of source directories and the reuse of them across presentations. Landslide configuration files use the cfg
syntax. If you know ini
files, you get the picture. Below is a sample configuration file:
[landslide]
theme = /path/to/my/beautiful/theme
source = 0_my_first_slides.md
a_directory
another_directory
now_a_slide.markdown
another_one.rst
destination = myWonderfulPresentation.html
css = my_first_stylesheet.css
my_other_stylesheet.css
js = jquery.js
my_fancy_javascript.js
relative = True
linenos = inline
Don't forget to declare the [landslide]
section.
All configuration files must end in the .cfg extension.
To generate the presentation as configured, just run:
$ cd /path/to/my/presentation/sources
$ landslide config.cfg
You can use macros to enhance your presentation:
Add notes to your slides using the .notes:
keyword, eg.:
# My Slide Title
.notes: These are my notes, hidden by default
My visible content goes here
You can toggle display of notes by pressing the 2
key.
Some other macros are also available by default: .fx: foo bar
will add the foo
and bar
classes to the corresponding slide <div>
element, easing styling of your presentation using CSS.
You can also add presenter notes to each slide by following the slide content with a heading entitled "Presenter Notes". Press the 'p' key to open the presenter view.
Macros are used to transform the HTML contents of your slide.
You can register your own macros by creating landslide.macro.Macro
derived classes, implementing a process(content, source=None)
method and returning a tuple containing the modified contents and some css classes you may be wanting to add to your slide <div>
element. For example:
!python
import landslide
class MyMacro(landslide.Macro):
def process(self, content, source=None):
return content + '<p>plop</p>', ['plopped_slide']
g = landslide.generator.Generator(source='toto.md')
g.register_macro(MyMacro)
print g.render()
This will render any slide as below:
!html
<div class="slide plopped_slide">
<header><h2>foo</h2></header>
<section>
<p>my slide contents</p>
<p>plop></p>
</section>
</div>
$ landslide slides.md -d ~/MyPresentations/KeynoteKiller.html
$ landslide slides/
$ landslide slides.md -o | tidy
$ landslide slides.md -t mytheme
$ landslide slides.md -t /path/to/theme/dir
$ landslide slides.md -i
$ landslide slides.md -d PowerpointIsDead.pdf
A Landslide theme is a directory following this simple structure:
mytheme/
|-- base.html
|-- css
| |-- print.css
| `-- screen.css
`-- js
`-- slides.js
If a theme does not provide HTML and JS files, those from the default theme will be used. CSS is not optional.
Last, you can also copy the whole theme directory to your presentation one by passing the --copy-theme
option to the landslide
command:
$ landslide slides.md -t /path/to/some/theme --copy-theme
If you don't want to bother making your own theme for tweaking up a bit your presentation style and/or add some interactivity using tiny bits of Javascript, you can include your own user css and js files to the generated presentation.
This feature is only available if you use a landslide configuration file, by setting the css
and/or js
flags:
[landslide]
theme = /path/to/my/beautiful/theme
source = slides.mdown
css = custom.css
js = jquery.js
powerpoint.js
These will link the custom.css
stylesheet and both the jquery.js
and powerpoint.js
files within the <head>
section of the presentation html file.
NOTE: Paths to the css and js files must be relative to the directory you're running the landslide
command from.
If you intend to publish your HTML presentation online, you'll have to use the --relative
option, as well as the --copy-theme
one to have all asset links relative to the root of your presentation;
$ landslide slides.md --relative --copy-theme
That way, you'll just have to host the whole presentation directory to a webserver. Of course, no Python nor PHP nor anything else than a HTTP webserver (like Apache) is required to host a landslide presentation.
Check out a Landslide presentation customized this way.
The base.html
must be a Jinja2 template file where you can harness the following template variables:
css
: the stylesheet contents, available via two keys,print
andscreen
, both having:- a
path_url
key storing the url to the asset file path - a
contents
key storing the asset contents
- a
js
: the javascript contents, having:- a
path_url
key storing the url to the asset file path - a
contents
key storing the asset contents
- a
slides
: the slides list, each one having these properties:header
: the slide titlecontent
: the slide contentsnumber
: the slide number
embed
: is the current document a standalone one?num_slides
: the number of slides in current presentationtoc
: the Table of Contents, listing sections of the document. Each section has these properties available:title
: the section titlenumber
: the slide number of the sectionsub
: subsections, if any
- To change HTML5 presentation styles, tweak the
css/screen.css
stylesheet bundled with the theme you are using - For PDF, modify the
css/print.css
