Running the slides

The slides are made using the go present syntax which has its own tooling.

The project maintains an up-to-date deployed version of the slides on lectures.course-go.dev.

The only disadvantage is that this version does not allow you to run the Go code presented on the slides for security reasons. To run the Go code, you must run the slides locally.

Running locally

Using Docker

You can use an already pre-built container image with lecture slides.

docker run -p "3999:3999" \
    ghcr.io/course-go/lectures:latest \
    present -http=:3999

Using present directly

Or you can run the slides locally using the Go present CLI.

Clone the repository

git clone git@github.com:course-go/lectures.git

Installation

Install Go if you do not have it yet.

Install the CLI present tool using Go install:

go install golang.org/x/tools/cmd/present@latest

This installs the present executable into your $GOPATH/bin directory if GOPATH is set or the $HOME/go/bin directory otherwise.

Usage

Make sure that the directory with the present executable is in your $PATH.

After that, running the present tool is simple:

present

Alternatively, you can specify on which address the server should listen:

present http=:8080

A webserver is run on the specified address. You can now preview the slides using your favourite web browser.
