How can I add a vertical slides about hacker-slides

[jacksingleton]

HackerSlides 0.4 with support for vertical slides using '--' on a new line is now available in the app store.

Thanks @jeau !

According to this source: http://www.relishapp.com/jedcn/reveal-ck/docs/slides-with-markdown#creating-a-single-column-of-vertical-slides

The vertical slides should be possible with ***which I tested and unfortunately it didn't work.

[JamborJan]

I can use the html notation instead of markdown but then I have to use completely html in a section. Is this the right way to do it?

#### Heading markdown

I cannot add vertical slides

---
<section>
<h4>Heading html</h4>

<ul>
<li>I can add vertical slides with section tags</li>
<li>everything needs to be html</li>
<li>no markdown</li>
</ul>

</section>

<section>
<h4>Even Tables work here</h4>
<table>
<thead>
    <tr>
        <th>Item</th>
        <th>Value</th>
        <th>Quantity</th>
    </tr>
</thead>
<tbody>
    <tr>
        <td>Apples</td>
        <td>$1</td>
        <td>7</td>
    </tr>
</tbody>
</table>

</section>
---
End

Hey thanks for bringing this up!

I didn't include the vertical slides in this release as I was trying to keep it very minimal - but it would be trivial to add.

Just need to decide what separator to use.

What do you think would look best? The default was actually "\n\n" or two blank lines. This looks nice in markdown but had the odd effect of pushing everything into a vertical slide while you were editing the markdown and happened to have two newlines in a row momentarily.

[JamborJan]

What about the 3 asterisks like mentioned in the one source I posted?

At the moment 3 asterisks make a line, don't know if this is something which is required / needed / used.

It would make it easy:

• 3 dashes = new horizontal slide
• 3 asterisks = new vertical slide

[jacksingleton]

Sure, will be in the next release!

Hi, I don't think this has been included yet, and I just wanted to chip in. Am loving hacker-slides, but I use *** to give me a horizontal line on a page. (see screenshot). I'd like to not lose that feature.

[jacksingleton]

Thanks @birdsarah, will pick something other than '***'

[ar-jan]

Hi! I'm trying out Hacker Slides. Has the option for vertical slides been added?

[jacksingleton]

@ar-jan I'm afraid this didn't make it into the last release. I might be able to do another release this weekend.

[ar-jan]

That would be great - then I might use it on Monday :)

[zeigerpuppy]

Vertical slides would be great, it really helps in organising slides well
The standard reveal.js syntax is

-- 

two dashes for vertical slides (instead of --- for a usual slide)

[jeau]

with this standard syntax (two dashes), the solution is quite simple

Jack, you only have to add this line just after line 40 in this file js/slides.js

'data-separator-vertical': "^-( *)-( *-*)*"

[jacksingleton]

Thanks @jeau

It will be slightly more work than that in order to get the preview to auto-scroll to the correct vertical slide.

Here is the line where we change the slide automatically:

https://github.com/jacksingleton/hacker-slides/blob/master/static/js/index.js#L46

Following the method calls back from there (all in the same file) will get you to currentCursorSlide which needs to know about the vertical slides.

If you have the time to give it a go and test locally I'd welcome a PR! Please reach out if you have any questions or run into any issues.

Jack

[jeau]

You are right. I did not verify the editor field before launching this fix.

I try to solve the problem but I don't understand the principle of the numbering of the horizontal and vertical slides

[jeau]

I found a response to my question. We must send two arguments: the first for the horizontal slide number, the second for me vertical slide number (if there)

args: [currentSlide.h, currentSlide.v]

il will send a PR ASAP.

Jeau

[zeigerpuppy]

happy to test changes here too,

I made the change to slide.js after line 40, but I guess some other changes are required before vertical slides will work!

[higyigma]

Please give updates! Love it, just wish it had vertical as everyone else has said.

[jacksingleton]

@jeau has put in the PR and I should have time to review merge and publish an update this weekend.

@zeigerpuppy that would be really helpful, especially if you could give it a go before the weekend

Thanks for helping out everyone :)

[zeigerpuppy]

Working great, thanks!
one little issue though, not sure if it's related to the change, but when typing the heading of a new slide and the preview is updating to the new slide, the editor seems to drop some key presses, ( type "Heading" and "eading" comes out).

Ok, a bit more testing, the problem is quite general, seems to drop a character when the preview updates (OS X 10.9, Firefox)
looks like this is the same as #21
maybe vertical slides have resurrected this problem?
I'll open a new issue.
