slide-serve

i really like the idea behind slide-html and the Takahashi method

you only need to learn 5 pseudo-markdown rules and a few annotations to build a nice presentation.

for really fast slide-creation and iteration and a good developer-experience i created this server

and for a good talk, you can control the presentation from the presenter view, including the next slide and your speaker notes (example from the quickstart presentation)

presenter-view

quickstart

i added a quickstart package in the repository, with my own styles and short demos from all features

just download the latest binary for your platform from the release page, place it somewhere and start

./slide-serve -dir path/to/quickstart

and visit http://127.0.0.1:8080

features

just write plaintext files, no need to think about html or indents
- you can even write more than one plaintext file, they are added in alphanumerical order
start with the -dev flag to auto reload the browser on that slide you just edited
- this is just awesome!
just go to http://127.0.0.1:8080/presenter and controll the presentation from the presenter view!
- see the current and the next slide
- see the speaker-@notes
add styles and background images next to your content
- no hardcoded slide-numbers in css
- don't count your slides, i'll do it for you ;)
syntax highlighter with chroma
use local images
add small javascripts for the last bits of awesomeness
- take a look at useful snippets for an example

your presentation

your slide-files must end with .md to gets loaded
styles.css in your presentation-root dir is automaticly added to your presentation
your presentation directory is routed to http://localhost:8080/static/ so you can access local images or fonts - this is important for your custom stylesheets!

syntax additions

@img/imagename.gif
@css/stylesheet.css
@js/jsfile.js
@code/language
@append
@hidden
@note

the path is relative to your presentation directory, if you like to create an image folder it would change to @img/images/imagename.gif

with die @code annotation, the code-formatting is set for this slide

note: instead of writing the harcoded slide number, you should use the SLIDENUMBER placeholder

@code/css
.slide-SLIDENUMBER h1 { 
  color: #fff; 
  text-shadow: 1px 1px 3px #333; 
}

example slide with background image and stylesheet:

# AWESOME
.
@img/example_bg.jpg
@css/whiteHeadline.css

with the @js annotation, you can add javascript to your slide - the code will run in the moment you enter the slide.

# javascript!
@js/jsdemo.js

2 variables are available: _slide is your current slide-div, and _slideIndex - is your slide index... obviously

the jsdemo looks like

_slide.style.backgroundColor = "red"
setTimeout(() => {
  _slide.style.backgroundColor = "inherit"
}, 1000)

@append appends the current slide to the previous, so you don't have to repeat the whole content.

following example still produces 2 slides, but the second with #this is prepended

# this is

# awesome
@append

example presentation: https://github.com/cdreier/slide-serve/tree/master/example

to see the example presentation, just run slide-serve without any flags

syntax highlighter

i used chroma for syntax highlightning.

just tell me what language you are using on your slide (with @code/lang) and you are good to go.

with the -syntaxhl start flag you can set the highlighter theme (there is a list with all the themes). the default is monokai

example (the position of the @code annotation does not matter)

# CSS backgrounds
@code/css
  .slide-12 {
    background: url("icon.png"),
                url("bg.png");
    background-repeat: no-repeat, repeat;
    background-size: 40%, auto;
    background-position: bottom right;
  }

useful snippets

list items popping up

first, lets make the paragraphs looks like list-items

.slide-SLIDENUMBER .slide-content p {
  list-style-type: disc; 
  display: list-item;
  text-align: left;
}

and then use append for every item

# lists
@css/list.css

new list item 
@append

next item
@append

item 3
@append

restarting gifs

as gifs are looping in the background, this script reloads the gif every time you enter the slide

// restartGif.js
function getBackgroundImageUrl(element){
  var styles = getComputedStyle(element)
  return styles.backgroundImage.replace("url(\"", "").replace("\")", "")
}
var url = getBackgroundImageUrl(_slide)
var reloadUrl = url + "?" + Math.random()
_slide.style.backgroundImage = "url('" + reloadUrl + "')"

and in an example slide

.
@img/funnyCat.gif
@js/restartGif.js

no image scaling

in the past, i needed a down-scaling of the images - if you want to reset this behaviour, add this to your styles.css

.slide {
  background-size: unset !important;
}

add a logo on every slide

i added an empty div at the end of the presentation HTML, so we can just use it in our global styles.css

#logo {
  position: fixed;
  right: 10px;
  bottom: 10px;
  font-family: Vollkorn;
  background-color: #e2e4e6;
  background-image: url("/static/images/your_logo.png");
  background-repeat: no-repeat;
}

printing

the default print styles from slide-html are included per default, so you can print a summary of your presentation.

with the -pdf flag, the styles are changed for printing the full slides, or to export to a pdf.

if something wont fit with your presentation styles, you can overwrite the print styles:

@media print {
  @page {size: landscape}

  /* ... */

  .slide h1 {
		font-size: 8rem !important;
	}
	.slide p {
		font-size: 2rem !important;
	}

}

export

to export as static html file you can use the subcommand export slide-serve [global Flags] export [?dest="Destination folder"]

NAME:
   slide-serve export - export slides

USAGE:
   slide-serve export [command options] [arguments...]

OPTIONS:
   --dest value  destination folder (default: "export")

cli flags

-dev

start with -dev or -dev true to enable auto-reloading (default false)
still much awesome feature!

-dir

this is the directory of your presentation (default "example")

-port

http port the server is starting on (default "8080")

-syntaxhl

string with the highlighter theme for your code (default "monokai")

-ratio

slide ratio, possible values: 4x3, 16x9 or 16x10 (default "16x9")

-title

html title in the browser (default "Slide")

-pdf

overwrite the summary print styles with full slide prints (default false)

-click

on default you only navigate with arrow keys, this enabled 'next slide' on click

build on your own

i used pkger to embedd the assets in the binary, you should check it out!

deployment

You can deploy on Zeit Now for example by doing the following:

npm install -g now
Run your presentation locally without development mode
Create an html directory: mkdir html
Inside of the directory do a curl: curl localhost:8080 -o index.html

Create a now.json file with something like this:

{
  "version": 2,
  "name": "name-of-the-presentation",
  "alias": [
    "name-of-the-presentation"
  ]
} ```

If you have pictures / fonts, create a symlink a folder called static. f.e. ln -s <place-with-images> static/images
Run now
Now will deploy your presentation.
To make it available on https://name-of-the-presentation.now.sh you have to run: now alias
