Add support for a PDF export with speaker notes

[hasalex]

I need a PDF export of my slides, in the same way than OOo Note's view. A4 pages,the first part of each page contains the slide itself and the second part contains the speaker notes.

I have a stylesheet that work with Chrome's "Export as PDF" feature, but I don't know how to switch to the stylesheet. Maybe a module, like the overview, that switches to a "slides with notes" view.

Any idea ?

I switch to an other option, based on gulp. It's probably simpler, and it fits my personal need.

With the regular gulp commands, It uses the print.styl file, and when I add -n to the gulp command, it uses the print-notes.styl.

I've put the feature in my fork at https://github.com/hasalex/presentation-bespoke-starter/tree/export-pdf-notes.

Tell me if you're interested with a PR.

@hasalex Good idea! I tried implementing this in my project and get the following error:

[14:12:11] Plumber found unhandled error:

I created a variables.styl and required it at the top of main.styl. Its contents are as follows:

rem-calc(value)
  ((u = unit(value)) is "px") ? unit(round(value/16, 4), "rem") : value

$slide-width = 640px
$slide-height = 360px

@mraible A small checklist:

• create variables.styl and print-notes.styl
• add @require './variables' in main.styl
• remove @require './print' in main.styl
• add the dev dependency to gulp-concat in package.json
• add concat = require('gulp-concat') in gulpfile.js
• update the css task in gulpfile.js

With all that stuff, it seems to be working. Yet there's some layout to arrange...
I'll prepare a PR.

@mraible BTW it should fix your problem with the regular export to PDF, as the gulp task add the print.styl or print-notes.styl file at the end of the stylesheet.

[mraible]

@hasalex That worked - thanks!

This is looking really good. I'll do some review and see if we can get this integrated into this project.

Btw, if you use gulp-concat, don't forget to add it to package.json.

[hasalex]

Thanks for pointing me the package.json, @mojavelinux. I've updated the check list.
