Ever given a Slide Show and needed to switch over to Vim?
Now you don't ever have to switch again. You're already there.
Vroom lets you create your slides in a single file using a Wiki-like
style, much like Spork and Sporx do. The difference is that your slides
don't compile to HTML or JavaScript or XUL. They get turned into a set
of files that begin with '0', like '03' or '07c' or ''.
The slides are named in alphabetic order. That means you can bring them
all into a Vim session with the command: C<vim 0*>. C<vroom --vroom>
does exactly that.
You can do things like advance to the next slide with the spacebar.
Vroom creates a file called C<./.vimrc> with helpful key mappings for
navigating a slideshow. See L<KEY MAPPINGS> below.
Please note that you will need the following line in your
C<$HOME/.vimrc> file in order to pick up the local C<.vimrc> file.
set exrc
Vroom takes advantage of Vim's syntax highlighting. It also lets you run
slides that contain code.
Since Vim is an editor, you can change your slides during the show.
Vroom has a few command line options:
=item vroom --new
Write an example C<slides.vroom> file. This example contains all the
config options and also examples of all the Vroom syntax features.
=item vroom --vroom
Compile (create) the slides files from the input file and start vim
=item vroom --compile
Just compile the slides.
=item vroom --html
Publish the slides to HTML, with embedded JavaScript to navigate with
the spacebar and backspace keys. Created in the C<html/> subdirectory.
=item vroom --text
Publish the slides to plain text. This action uses all the text slides in
their unsplit form. Created in the C<text/> subdirectory.
=item vroom --clean
Clean up all the compiled output files.
=item vroom --ghpublish
Creates a shell script in the current directory, that is intended to
publish your slides to the special GitHub branch called gh-pages. See
This command does NOT run the script. It merely creates it for you. It is up
to you to review the script and run it (if it makes sense on your system).
=item vroom <action> --skip=#
The skip option takes a number as its input and skips that number of
files during compilation. This is useful when you are polishing your slides
and are finished with the first 50. You can say:
vroom --vroom --skip=50
and it will start on slide #51.
=item vroom <action> --input=<file_name>
This option lets you specify an alternate input file name, instead of the
default one, C<slides.vroom>.
Here is an example slides.vroom file:
---- config
# These are YAML settings for Vroom
title: My Spiffy Slideshow
height: 84
width: 20
# skip: 12 # Skip 12 slides. Useful when making slides.
# auto_size: 1 # Determines height/width automatically
---- center
My Presentation
by Ingy
== Stuff I care about:
* Foo
+* Bar
+* Baz
---- perl,i10
# Perl code indented 10 spaces
use Vroom;
print "Hello World";
---- center
A line that starts with '==' is a header line. It will be centered.
Lines that begin with a '+' cause vroom to split the slide there,
causing an animation effect.
Each slide can have one or more configuration options. Options are
a comma separated list that follow the '----' header for a slide.
Like this:
---- config
---- center
---- perl,i20
---- include file-name
---- replace
---- skip
=item config
The slide is really a yaml configuration. It will not be displayed
in the presentation, but will tell vroom what to do from that point
Usually, a C<config> slide is the first thing in your input file, but
you can use more than one config slide.
=item center
Center the contents of the slide.
=item i##
'i' followed by a number means to indent the contents by the number of
=item i-##
'i' followed by a negative number means to strip that number of leading
characters from the contents of the slide. This can be useful if you need
to have characters special to Vroom at the beginning of your lines,
for example if the contents of your slide is unified diff output.
=item perl,ruby,python,php,javascript,haskell,actionscript,html,yaml,xml,json,make,shell,diff
Specifies that the slide is one of those syntaxen, and that the
appropriate file extension will be used, thus causing vim to syntax
highlight the slide.
=item include file-path-name
Replace the line with the contents of the specified file. Useful to
include long files that would make your slides file unruly.
=item replace
With the C<replace> option, the '+' animations in the slide cause the
content to replace the previous partial slide, rather than append to it.
=item skip
Ignore the following slide completely.
You can specify the following configuration options in a config slide:
=item title: <text>
The title of your presentation.
=item height: <number>
The number of lines in the terminal you plan to use when presenting the
show. Used for centering the content.
=item width: <number>
The number of columns in the terminal you plan to use when presenting
the show. Used for centering the content.
=item auto_size: <0|1>
When set to 1, the height/width options above will be ignored and
determined each time you start the slideshow.
=item indent: <number>
All slides will be indented by this number of spaces by default.
=item list_indent: <number>
Auto detect slides that have lists in them, and indent them by the
specified number of columns.
=item vim: <name>
You can specify the name of the vim executable to use. If you set this to
C<gvim> special gvim support will be provided.
=item GVim options
The following options are available, if your vim option is set to gvim.
fuopt: maxhorz,maxvert
guioptions: egmLtT
guicursor: a:blinkon0-ver25-Cursor
guifont: Bitstream_Vera_Sans_Mono:h18
These are all documented by gvim's help system. Please see that for more
These are the standard key mappings specified in the local C<.vimrc>.
=item <SPACE>
Advance one slide.
Go back one slide.
=item ??
Bring up the help screen.
=item RR (or R -- deprecated)
If the current slide is declared Perl, Python, Ruby, PHP, Haskell or
JavaScript, then run it accordingly.
=item QQ
Quit Vroom.
=item VV
Since these vim options apply while editing the C<slides.vroom> file
(yes, beware), you can use this shortcut to launch Vroom on the current
contents whilst writing your slides.
=item EE
Edit the file that the cursor is on the filename of.
You can put file path names in your slides, and then easily bring them
up during your presentation.
=item OO
On a Mac, run the OS X C<open> command on the argument that your cursor is on.
For instance, if you want to display an image, you could put the file
path of the image in your slide, then use OO to launch it.
You can create a file called C<.vroom/vimrc> in your home directory. If
vroom sees this file, it will append it onto every local C<.vimrc> file
it creates.
Use this file to specify your own custom vim settings for all your vroom
You can also create a file called C<.vroom/gvimrc> for gvim overrides,
if you are using gvim.
=head1 USING MacVim OR gvim
If you have a Mac, you really should try using MacVim for Vroom slide
shows. You can run it in fullscreen mode, and it looks kinda
To do this, set the vim option in your config section:
vim: gvim
NOTE: On my Mac, I have gvim symlinked to mvim, which is a smart startup
script that ships with MacVim. Ping me, if you have questions
about this setup.
I(ngy) put all my public talks on github. I think it is an excellent way
to publish your slides and give people a url to review them. Here are
the things I do to make this work well:
1) I create a repository for every presentation I give. The name of
the repo is of the form <topic>-<event/time>-talk. You can go to
L<> and look for the repos ending
with C<-talk>.
2) GitHub has a feature called gh-pages that you can use to create a
website for each github repo. I use this feature to publish the html
output of my talk. I do something like this:
vroom --html
mv html /tmp
git branch gh-pages
git checkout gh-pages
rm -r *.html
mv /tmp/html/* .
rmdir /tmp/html
git add .
git commit -m 'Publish my slides'
git push origin gh-pages
git checkout master
2B) Vroom comes with a C<--ghpublish> option. If you run:
> vroom -ghpublish
it will generate a script called C<ghpublish> that contains commands like the
ones above, to publish your slides to a gh-pages branch.
3) If my repo is called C<vroom-yapcna2009-talk>, then after I publish
the talk to the gh-pages branch, it will be available as
I then link this url from
L<> as the Homepage
You can see an example of a talk published to HTML and posted via gh-pages
at L<>.
