DESCRIPTION
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 '05b.pl'.
The slides are named in alphabetic order. That means you can bring them all into a Vim session with the command: "vim 0*". "vroom --vroom" does exactly that.
You can do things like advance to the next slide with the spacebar. Vroom creates a file called "./.vimrc" with helpful key mappings for navigating a slideshow. See "KEY MAPPINGS" below.
Please note that you will need the following line in your "$HOME/.vimrc" file in order to pick up the local ".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.
COMMAND USAGE
Vroom has a few command line options:
vroom --new
Write an example "slides.vroom" file. This example contains all the
config options and also examples of all the Vroom syntax features.
vroom --vroom
Compile (create) the slides files from the input file and start vim
show.
vroom --compile
Just compile the slides.
vroom --html
Publish the slides to HTML, with embedded JavaScript to navigate
with the spacebar and backspace keys. Created in the "html/"
subdirectory.
vroom --text
Publish the slides to plain text. This action uses all the text
slides in their unsplit form. Created in the "text/" subdirectory.
vroom --clean
Clean up all the compiled output files.
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 "GITHUB NOTES" below.
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).
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.
vroom <action> --input=<file_name>
This option lets you specify an alternate input file name, instead
of the default one, "slides.vroom".
INPUT FORMAT
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.
---- 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
THE END
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.
CONFIGURATION OPTIONS
Each slide can have one or more configuration options. Options are a comma separated list that follow the '----' header for a slide. Like
---- config
---- center
---- perl,i20
---- include file-name
---- replace
---- skip
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
forward.
Usually, a "config" slide is the first thing in your input file, but
you can use more than one config slide.
center
Center the contents of the slide.
i## 'i' followed by a number means to indent the contents by the number
of characters.
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.
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.
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.
replace
With the "replace" option, the '+' animations in the slide cause the
content to replace the previous partial slide, rather than append to
it.
skip
Ignore the following slide completely.
CONFIG SLIDE OPTIONS
You can specify the following configuration options in a config slide:
title: <text>
The title of your presentation.
height: <number>
The number of lines in the terminal you plan to use when presenting
the show. Used for centering the content.
width: <number>
The number of columns in the terminal you plan to use when
presenting the show. Used for centering the content.
indent: <number>
All slides will be indented by this number of spaces by default.
list_indent: <number>
Auto detect slides that have lists in them, and indent them by the
specified number of columns.
vim: <name>
You can specify the name of the vim executable to use. If you set
this to "gvim" special gvim support will be provided.
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 information.
KEY MAPPINGS
These are the standard key mappings specified in the local ".vimrc".
<SPACE>
Advance one slide.
<BACKSPACE>
Go back one slide.
?? Bring up the help screen.
RR (or R -- deprecated)
If the current slide is declared Perl, Python, Ruby, PHP, Haskell or
JavaScript, then run it accordingly.
QQ Quit Vroom.
VV Since these vim options apply while editing the "slides.vroom" file
(yes, beware), you can use this shortcut to launch Vroom on the
current contents whilst writing your slides.
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.
OO On a Mac, run the OS X "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.
CUSTOM CONFIGURATION
You can create a file called ".vroom/vimrc" in your home directory. If vroom sees this file, it will append it onto every local ".vimrc" file it creates.
Use this file to specify your own custom vim settings for all your vroom presentations.
You can also create a file called ".vroom/gvimrc" for gvim overrides, if you are using gvim.
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 professional.
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.
GITHUB NOTES
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:
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 "--ghpublish" option. If you run:
> vroom -ghpublish
it will generate a script called "ghpublish" that contains commands like the ones above, to publish your slides to a gh-pages branch.
3) If my repo is called "vroom-yapcna2009-talk", then after I publish the talk to the gh-pages branch, it will be available as <http://ingydotnet.github.com/vroom-yapcna2009-talk>. I then link this url from <http://github.com/ingydotnet/vroom-yapcna2009-talk> as the Homepage url.
You can see an example of a talk published to HTML and posted via gh-pages at <http://ingydotnet.github.com/vroom-pm/>.
