# Goveal
|
|
|
|
[](https://github.com/baez90/goveal/actions)
|
|
|
|
Goveal is very small and very simple tool that reads Markdown from a given file, renders it into an HTML template and serves it as local HTTP server.
|
|
Right now Goveal uses Reveal.js 4.2.1 to create presentations and therefore also includes all features of Reveal.js 4.2.1.
|
|
|
|
In contrary to Reveal.js `goveal` ships with its own Markdown parser and renderer which is why some features are working slightly different from Reveal.js.
|
|
See [Markdown](#markdown) for further details.
|
|
|
|
Besides all features from Reveal.js `goveal` comes with first class support for [mermaid-js](https://mermaid-js.github.io/).
|
|
Just inline your diagrams as code and enjoy!
|
|
|
|
## Install
|
|
|
|
The easiest and fastest way to install Goveal is to use a pre-built binary from the [releases](https://github.com/baez90/goveal/releases/latest).
|
|
|
|
There's also a pre-built container image available you can use if you don't want to download the binary.
|
|
|
|
### Build from source
|
|
|
|
If you have Go in the latest version installed you can also build your own version of Goveal:
|
|
|
|
```shell
|
|
task build
|
|
```
|
|
|
|
Requirements:
|
|
|
|
- [task](https://taskfile.dev/)
|
|
- _Optional:_ [goreleaser](https://goreleaser.com/) (for `task snapshot-release` to build all binaries)
|
|
|
|
_Note: All script tasks in the [Taskfile.yml](Taskfile.yml) are meant to be executed with Linux/MacOS. Binaries for
|
|
Windows are provided but not tested!_
|
|
|
|
## Usage
|
|
|
|
### Local installation
|
|
|
|
```bash
|
|
goveal serve ./slides.md
|
|
```
|
|
|
|
| Param | Description | Default value |
|
|
| ---------------- | --------------------------------------------- | ----------------------- |
|
|
| `--host` | Hostname the binary is listening on | `127.0.0.1` |
|
|
| `--port` | Port the binary is listening on | `2233` |
|
|
| `--config` | Path to the config file see [config](#config) | `$HOME/goveal:./goveal` |
|
|
| `--open-browser` | Open a browser after starting the web server | `true` |
|
|
| `-h` / `--help` | shows help | |
|
|
|
|
### Container
|
|
|
|
Assuming your slides are in a file called `slides.md` in the current directory, you can start the presentation like
|
|
this:
|
|
|
|
```shell
|
|
podman/docker run --rm -ti -v `pwd`:/work -w /work -p 2233:2233 ghcr.io/baez90/goveal:0 serve --host 0.0.0.0 slides.md
|
|
```
|
|
|
|
By default `goveal` only listens on `127.0.0.1`. To allow traffic from outside of the container you've to change the
|
|
binding to `0.0.0.0`.
|
|
|
|
## Config
|
|
|
|
Goveal supports multiple configuration mechanisms. It tries to load a configuration file from `$HOME` or from `.`
|
|
i.e. `$HOME/goveal.yaml` or `$HOME/goveal.yml` or `./goveal.yaml` and so on.
|
|
|
|
The config allows setting a lot of options exposed by Reveal.js.
|
|
There are still a few missing, and I won't guarantee to support all options in the future.
|
|
|
|
Furthermore, `goveal` supports configuration hot reloading i.e. you can play around with different themes and the rendered
|
|
theme will be changed whenever you hit the save button!
|
|
|
|
See also an example at [`./examples/goveal.yaml`](./examples/goveal.yaml).
|
|
I try to keep the example up to date to cover **all** supported config options as kind of documentation.
|
|
|
|
## Markdown
|
|
|
|
A good point to start is the [slides.md](examples/slides.md) in the `examples` directory.
|
|
I try to showcase everyting possible with `goveal` in this presentation.
|
|
|
|
The most remarkable difference between `goveal` and the `marked` driven Reveal.js markdown is how line numbers in listings are working:
|
|
|
|
Reveal.js:
|
|
|
|
<pre lang="no-highlight"><code>```cs [1-2|3|4]
|
|
var i = 10;
|
|
for (var j = 0; j < i; j++) {
|
|
Console.WriteLine($"{j}");
|
|
}
|
|
```</code></pre>
|
|
|
|
`goveal`:
|
|
|
|
<pre lang="no-highlight"><code>
|
|
{line-numbers="1-2|3|4"}
|
|
```cs
|
|
var i = 10;
|
|
for (var j = 0; j < i; j++) {
|
|
Console.WriteLine($"{j}");
|
|
}
|
|
```</code></pre>
|
|
|
|
This is because the Markdown parser used in `goveal` currently does not support additional attributes for code blocks.
|
|
|
|
## Custom CSS
|
|
|
|
To add custom CSS as theme overrides use a config file and add the `stylesheets` property. It takes a list of relative (
|
|
mandatory!) paths to CSS files that are included automatacally after the page was loaded so that they really overload
|
|
everything added by Reveal and plugins.
|
|
|
|
Changes in the custom CSS files are monitored and propagated via SSE to the presentation immediately.
|
|
No page reload necessary!
|
|
|
|
The sample configuration file [`./examples/goveal.yaml`](./examples/goveal.yaml) also contains a sample how to add
|
|
custom CSS. |
