A re-done and re-factored verison of my old presentation software I wrote in 10th grade

Grezi allows you to write presentations using plain text. It's designed to make presentations that are very engaging, with little effort on your part.

Note that: Grezi depends on the Helix text editor for syntax highlighting. If you don't have Helix, you can find a binary here

Grezi is designed to be used with an IDE (Helix is what I've been using). Not only does the language have syntax highlighting and indentation hints thanks to the tree-sitter parser, but it also has an embedded language server that makes the process of making slideshows easier. Features of the LSP include

• Rename symbol support
• Goto declaration support
• Goto reference support
• Code formatting
• Semantic tokens support (Syntax highlighting in non tree-sitter editors, eg. VSCode)
• Errors and diagnostics support
• Hot reloading as you type
• Folding Ranges

You can use the LSP by runing grezi with the --lsp argument

There's a vscode extension under the grezi-vscode/ folder. Once you install it as a VSIX in your vscode instance, you need to point it at the location of the grezi binary for it to work.

Grezi allows you to export your presentation to PDF, PostScript, and many image formats using the cairo library. Just use the export flag like so

grezi -eo new.pdf new.grz 
grezi -eo new.ps new.grz 
grezi -eo new.png -i 6 new.grz 
grezi -eo new.png -i 6..8 new.grz 
grezi -eo new.png -i 6..8 -s 512 new.grz 
grezi -eo new.png -i 6..8 -s 1920x1080 new.grz 

Warning: You can also export to SVG, however, this method is not very reliable.

Grezi can export to various static formats, but you can also share the animated version of your presentations via the WebAssembly runtime. Using the runtime is easy

1. Install these

• trunk
• brotli
• wasm-opt
• GNU parallel

2. Build the WebAssembly runtime

trunk build --release

3. Export any slideshows you want to share to the .slideshow format (A custom format that packs your slideshow, all used fonts, and all used images together into one file)

grezi -eo new.slideshow new.grz
grezi -eo another.slideshow another.grz

4. Move the slideshows you want to share into the dist/ directory that trunk created in step 2

mv new.slideshow dist/
mv another.slideshow dist/

5. Run the opt.sh script to compress everything and optimize the WASM binary

sh opt.sh

Optionally, pass a directory to opt.sh to move all the slideshow files in it to the dist directory

sh opt.sh ~/slideshows/

6. Serve the dist/ directory with the server of your choice and go to this URL
