All the positioning parameters except data-x and data-y should be sticky, if set explicitly, so that you can set the rotation on a step, and all following steps keep the same rotation.

If I have a list, how can I emphasize the first item, then the second, etc. I wouldn't mind if they stayed emphasized as I move to the next. Can I do this with an ID or class?

Hi,

this might be a bit off-toppic as it doesn't seem to have anything to do with the usage of this promising piece of software. It concerns the installation procedure necessary to run this tool on a minimalistic linux computer (don't have a fully grown ubuntu machine).

After installing libxml2-dev, pip3, python3 (in parallel to python2) and some other packages, the installation procedure still does not run through successfully, regardless of how I try to start installation. Using pip or installing using the setup.py way...

e.g. sudo pip3 install hovercraft gives the following output (sorry for its length. Hopefully you see some hints):

There should be a simpler template for web-publishing that doesn't include the console.

I'm new to hovercraft, so forgive me if these already exists..

On another popular prenation tool there is a feature to blank the screen (in white or black). I find this very helpful when giving a presentation. I think b and w do this.

it would also be nice to have a background or outline for each slide.

if I could skip ahead +2 slides by typing + or -. Also if I could go to a specific slide perhaps : that would also be very helpful.

One last thing.. if I could set a timeout so that the presentation could run itself and perhaps in a loop. And in such a way that a user could click a button to skip ahead (think of a second person story click X to eat the fruit, click Y to run away...)

As is this software will be very useful in my next presentation, thank you

Thanks for a nice tool!

Is there an example on how to print a hovercraft presentation? If not, could one be added?

Sometimes it's useful to return back to some slide and then for example change direction of the movement. As an example you can look how reveal.js does that.

So it would be nice to specify position relative to some other slide:

:id: central_slide
----
...
----
:data-x: central_slide+1234

What do you think?

Hi,
When we use data-x for one slide, next slide will have the same effect. However, with data-rotate-x, next slide have default effect instead of data-rotate-x. It is intended ? Moreover, when we put thing before the first "------", all the slide are affected, exept for data-rotate-x.
Of course it's the same question for y and z axis.

Thoses issues are not major, since we can add the « :data-rotate-x: 100 » on each side if needed, but it can be an improvement to have a consistent logic in effects.

Of course thanks a lot for your work. Hovercraft was the exact tools I needed since a long time.

Steps need naming, either explicitly or after their heading. This is so you can have custom css on certain steps easily, no matter what step-number the step has.

Hi,

Hi Lennart, Hovercraft for me (plain-text-fileaholic..!) is a dream come true. However in order to prezifi my presentation I'd like to use a big image as background but it seems that at first attempt (without tweaking on positioning) it is put not in the center of the slide but a bit right, with a white margin on the left, why?

Examples from readthedocs.org do not work out of the box because of some missing CSS files:

$ hovercraft -a hovercraft.txt Hovercraft
[...]
IOError: [Errno 2] No such file or directory: '/path/where/I/was/hovercraft.css'

The error is coming from hoverecraft.txt line:

:css: hovercraft.css

hovercraft is installed (via pip) with a couple of hovercraft.css, but it's not clear which one is supposed to be used.

For the example tutorial.txt requiring tutorial.css, this CSS is not included in hovercraft distribution.

Could the examples in readthedocs state exactly what is supposed to be the compilation process?

Could you include a LICENSE or COPYING file in the repo and tarball you ship to PyPI?

A copy of this file would probably do it:
http://creativecommons.org/publicdomain/zero/1.0/legalcode.txt

Hi,

I just finished a long presentation with hovercraft and realize that it is annoying if all transitions are moves. Is it possible to add some boring transition like dissolving or blending?

Hi there

I have a small problem that is shown in this example:

----

Section
=======

subtitle
--------
Yay

----

other subtitle
--------------
Re-yay

I expect "subtitle" and "other subtitle" to have the same style, but the first one is h2 while the second one is h1. It seems the separator resets the sections adornment hierarchy.

It makes it complicated to have titles on each slides that are smaller than the big title on the first slide.

Am I understanding it wrong, or is this a bug here ?

Add instructions for how to make your own templates, with information on how to deal with the XSLT, specifically mention the resource:reST.xml include.

I've just realized that Hovercraft is "Python 3 only" after a comment on #29 .

That's mentioned in the trove classifiers list of the setup.py (showed in PyPi page) but not in the README nor in the doc. Moreover, there is any installation instructions in the documentation, so the common way $ pip install hovercraft fails (like or not, most people is still using python2.7)

Even though setup.py fails under python 2, pip seems to be able to install it. I need to find a way to stop that.

I installed hovercraft in Debian Wheezy, using the procedure below, but whenever I try to compile the example hovercraft presentation, I get a syntax error.
I'm a bit stuck on how to fix this.

Awesome project, unfortunately I'm unable to use it ! ;-)

This is probably a problem with my python3 env, just in case it isn't, below
is the stack trace I get when I launch hovecraft.

the virtualenv was created with :

When you want to publish your slides online, you typically do not want people to see all your messy and embarrasing notes. It should be possible to run hovercraft without including the notes in the output.

The help popup can possibly be annoying, a parameter to not show it for people who know Hovercrafts keys would be useful.

don't work! :)

I did a clean install in a virtualenv.

Starting hovercraft I got:

Traceback (most recent call last):
File "bin/hovercraft", line 9, in
load_entry_point('hovercraft==1.0b2', 'console_scripts', 'hovercraft')()
File "/tmp/hover/local/lib/python2.7/site-packages/hovercraft/init.py", line 10, in main

from .template import template_info_node
File "/tmp/hover/local/lib/python2.7/site-packages/hovercraft/template.py", line 2, in

ImportError: No module named configparser

Could be easily fixed using:

bin/pip install configparser

I resize my original image (just width) in order to make it fit on my slide, but unfortunately, even with center tag, the image is not centered on the page.

Hey!

deck2pdf works pretty well to export the presentation to pdf.

Is there a way to use this (or another) tool to export the presenter notes to pdf?

Thank you in advance!

The following, per the unit tests, works fine:

------------

:class: something-else

This is some text

While the following:

------------

:class: something-else

This is some text

------------

:class: something-else

This is some text

Produces this error:

New to this plugins. What's going on here? Please help. Thanks!

Just thought I'd share my experience with setting up an automated build for hovercraft with a web editor.
It works well as a full web-based presentation system.

Firstly, I set up hovercraft on my server

Secondly, I installed codiad on the same server
It's a web-based editor for code that allows editing the hovercraft .rst and .css in a browser
http://codiad.com/

Make sure your permissions are good

• set ownership for .rst and .css files as www-data so that codiad can edit them
• set the build directory as owned by hovercraft user

Set up a cron job to autobuild every minute
as hover user:

crontab -e

SHELL=/bin/bash
* * * * * source /opt/hover/.virtualenvs/env/bin/activate && cd /var/www/codiad/workspace/hovercraft/presentation && hovercraft presentation.rst output > /dev/null

Then you can edit your presentation using a web interface and have it built automatically as you go.
It would probably be good to script this a bit further and check for file changes so that there is no build process if the .rst has not changed

The default distance (currently a DEFAULT_MOVEMENT constant) between steps is 1600px, which seems to work fine. A parameter or a presentation-level field setting to change this might be useful.

The help should show when the H-key is pressed.

Hi,

Can we have support for Markdown in hovercraft? Maybe as a configurable option?

Radha.

Maybe there could be a field in the presentation to add css dependencies. For example:

:hovercraft-css: css/presentation.css

Then there could be more than one --extra-css file, and also no need to type it on the command line.

positions.txt, step 2, informs that you don't have to gove both x & y coords, which should presumably be give both coordinates.

Is it possible to include SVG images in the presentations?
This would be really useful, especially if it also allowed SVG animations to be embedded.

This is possible in sozi, for instance
http://sozi.baierouge.fr/

I have no ideas if it is complicated to add videos support. I thing that the syntax for the images can be used. Something like the following exemple can be great.

.. video:: path/to/videos.webm
    :height: 600px
    :width: 800px

For the moment, I use gif as a workaround, but native support of videos can be better.

When trying to preset "slideshow.rst" I got:

IOError: [Errno 2] No such file or directory: '/tmp/hover/examples/images/_dead_10.jpg'

Lennart, could hovercraft support Reveal.js-based presentations as well as Impress.js-based ones?

While the impress.js website works nicely in my browser (firefox on ubuntu 12.04), using hovercraft from a simple two-slide ReST file only produces a "dead" presentation. All of the suggested Keystrokes are ignored. How can i further debug this?

See https://bitbucket.org/pypa/pypi/issue/215/hovercraft-dependency-error

After # pip install hovercraft

$ hovercraft show
Traceback (most recent call last):
  File "/usr/bin/hovercraft", line 9, in <module>

    import configparser
ImportError: No module named configparser

# pip install configparser fixed that

Any chance for a jmpress.js template? It's meant to be compatible with impress.js markup, only it has some nice extras, like animated substeps governed by the data-jmpress attribute.

I have checked how a switch to jmpress.js would affect the presentation, and apparently, it broke the console and the help screen, but the rest of the presentation worked fine.

I have tried including html links in my slide but they are not rendered:

e.g.

Test Slide
==========

test html links

.. _pygments: http://pygments.org/

When hovercraft creates the presentation, the link is missing from the presentation, i.e.

<div class="step step-level-1" step="2" data-rotate-x="0" data-rotate-y="0" data-rotate-z="0" data-scale="1" data-x="3200" data-y="0" data-z="0"><h1 id="test-slide">Test Slide</h1><p>test html links</p></div></div>

I have also tried rendering the tutorial.rst (which has a hyperlink) and it does not get included either,
there are no errors on compiling the presentation

found that the following does produce proper links, is this just a syntax issue on my part or an actual problem?

Python_ is `my favourite
programming language`__.

I would like to make a slide with few pictures and text scattered around, so can I give a id to a specific element (text, image, ...) to set it up in the css file?

Using : id : set the id for the whole frame and so it easily allows to setup ONE element (eg, #scatteredframe img {...} ), but how to pinpoint the css to a single element?

Hi,
First of all thanks a lot for hovercraft, it's a really great tool!
I was using landslide before and I want to move on hovercraft. For some special reason I need to have the support of embed mode like in landslide in order to produce a only one html page with everythink inside (css, html, image...).

I would like to know If you will be interested to integrate this option If we do a PR ?

We can use the same args as landslide :

-i, --embed Embed stylesheet and javascript contents,
base64-encoded images in presentation to make a
standalone document

What do you think?
Thanks a lot for hovercraft I really enjoy it ;)

I was trying to set a class for an image, but I couldn't get it to work. I'm new to RST, so this is the code I figured out from the docs:

.. image:: img/img.jpg
    :class: myclass

The output creates the image, but the class attribute is missing. What am I doing wrong? I could successfully set the class attribute on a paragraph, but not on an image...

Getting this error:

I'm trying to create a custom template. I've copied the "default folder" to a folder name "my-theme". Calling overcraft with -t and pointing it at either the folder, or the template.cfg file results in the following error. Even pointing hovercraft at the shipped default template results in the same error.

I often rotate with data-rotate-y and therefore use data-z. As far as I can tell it doesn't accept relative positioning. Is this expected behaviour? Just wondering if there's a reason why data-z differs fom data-x and data-y.

I'm not sure if it's really an "issue" or my lack of understanding of how svg paths work.

I used a "horizontal" svg path - a line whose main direction is more or less "to the right". hovercraft did what I expected.

Then I used a "vertical" svg path, or actually several different ones: straight line down, or with several segments but more or less down, or a free-hand line going down. But every time, starting at that slide, the slide turned 90° and the direction was "mainly to the right" again.

Is this to be expected?
