Usage

Create a simple markdown file that contains your slides:

# Welcome to Slides
A terminal based presentation tool

---

## Everything is markdown
In fact, this entire presentation is a markdown file.

---

## Everything happens in your terminal
Create slides and present them without ever leaving your terminal.

---

## Code execution
```go
package main

import "fmt"

func main() {
  fmt.Println("Execute code directly inside the slides")
}
```

You can execute code inside your slides by pressing `<C-e>`,
the output of your command will be displayed at the end of the current slide.

---

## Pre-process slides

You can add a code block with three tildes (`~`) and write a command to run *before* displaying
the slides, the text inside the code block will be passed as `stdin` to the command
and the code block will be replaced with the `stdout` of the command.

```
~~~graph-easy --as=boxart
[ A ] - to -> [ B ]
~~~
```

The above will be pre-processed to look like:

┌───┐  to   ┌───┐
│ A │ ────> │ B │
└───┘       └───┘

For security reasons, you must pass a file that has execution permissions
for the slides to be pre-processed. You can use `chmod` to add these permissions.

```bash
chmod +x file.md
```

Checkout the example slides.

Then, to present, run:

slides presentation.md

If given a file name, slides will automatically look for changes in the file and update the presentation live.

slides also accepts input through stdin:

curl http://example.com/slides.md | slides

Go to the first slide with the following key sequence:

g g

Go to the next slide with any of the following key sequences:

space
right
down
enter
n
j
l
Page Down
number + any of the above (go forward n slides)

Go to the previous slide with any of the following key sequences:

left
up
p
h
k
N
Page Up
number + any of the above (go back n slides)

Go to a specific slide with the following key sequence:

number + G

Go to the last slide with the following key:

G

Search

To quickly jump to the right slide, you can use the search function.

Press /, enter your search term and press Enter
(The search term is interpreted as a regular expression. The /i flag causes case-insensitivity.).

Press ctrl+n after a search to go to the next search result.

Code Execution

If slides finds a code block on the current slides it can execute the code block and display the result as virtual text on the screen.

Press ctrl+e on a slide with a code block to execute it and display the result.

Pre-processing

You can add a code block with three tildes (~) and write a command to run before displaying the slides, the text inside the code block will be passed as stdin to the command and the code block will be replaced with the stdout of the command. Wrap the pre-processed block in three backticks to keep proper formatting and new lines.

```
~~~graph-easy --as=boxart
[ A ] - to -> [ B ]
~~~
```

The above will be pre-processed to look like:

┌───┐  to   ┌───┐
│ A │ ────> │ B │
└───┘       └───┘

For security reasons, you must pass a file that has execution permissions for the slides to be pre-processed. You can use chmod to add these permissions.

chmod +x file.md

Configuration

slides allows you to customize your presentation's look and feel with metadata at the top of your slides.md.

This section is entirely optional, slides will use sensible defaults if this section or any field in the section is omitted.

---
theme: ./path/to/theme.json
author: Gopher
date: MMMM dd, YYYY
paging: Slide %d / %d
---

theme: Path to json file containing a glamour theme, can also be a link to a remote json file which slides will fetch before presenting.
author: A string to display on the bottom-left corner of the presentation view. Defaults to the OS current user's full name. Can be empty to hide the author.
date: A string that is used to format today's date in the YYYY-MM-DD format. If the date is not a valid format, the string will be displayed. Defaults to YYYY-MM-DD.
paging: A string that contains 0 or more %d directives. The first %d will be replaced with the current slide number and the second %d will be replaced with the total slides count. Defaults to Slide %d / %d. You will need to surround the paging value with quotes if it starts with %.

Date format

Given the date January 02, 2006:

Value	Translates to
`YYYY`	2006
`YY`	06
`MMMM`	January
`MMM`	Jan
`MM`	01
`mm`	1
`DD`	02
`dd`	2

SSH

Slides is accessible over ssh if hosted on a machine through the slides serve [file] command.

On a machine, run:

slides serve [file]

Then, on another machine (or same machine), ssh into the port specified by the slides serve [file] command:

ssh 127.0.0.1 -p 53531

You will be able to access the presentation hosted over SSH! You can use this to present with slides from a computer that doesn't have slides installed, but does have ssh. Or, let your viewers have access to the slides on their own computer without needing to download slides and the presentation file.
