Requirements

• Officially supported Zig: Zig 0.13.0-dev.351+64ef45eb0 (you can get it from the Zig Releases page)

Installation

Use Zig to build the application binary. With a shell open in this project's directory:

zig build -Doptimize=ReleaseSafe

The binary will be available at zig-out/bin/zig-present.

Usage

See the Example for a sample presentation file or the Presentation section for info on the available presentation commands. Store this in a file with the .txt extension, like presentation.txt. Then, you can start the presentation like this:

$ zig-present presentation.txt

Presentation

Every zig-present file must start with the line !zig-present.

Lines starting with a / denote a command. All other lines are interpreted as text to print (empty lines and whitespace are preserved).

The most important command is /next_slide, which effectively creates a new slide within the presentation. See Commands for all of the commands.

Commands

A presentation file can contain pre-defined commands. See the following table for a glossary:

Command	Description	Example Usage

/stdout	Run the shell command and print the result.	/stdout date
