index.html
is rendered from Jinja templates and static data.
Front-End:
- HTML
- Tailwind CSS
- JavaScript
Rendering / Templating:
- The data for the website is stored in the
src/data
directory. - HTML templates are stored in the
src/templates
directory. - These files are interpreted by
templates.py
to generate the rendered HTML files inbuild
. - To generate the CSS file,
npx tailwindcss
is used to generate the required CSS tags. - JavaScript files are copied from
src/js
to thebuild/script
directory.
The fun begins! Terminal mode is an easter egg I wanted to add that ended up becoming the majority of this project.
The HTML for terminal mode is rendered in a similar fashion, although there's no template data at all. I reuse the same infrastructure for simplicity.
All of the logic behind terminal mode is written in C++, and compiled to
WebAssembly using Emscripten. Terminal mode also uses some JavaScript to act
as a bridge between Wasm and the DOM (in terminal_mode_interface.js
).
wash
: the WebAssembly SHell:
Terminal mode relies on a completely emulated filesystem, which contains the
contents of my website, but in textual format. The interface between these files
and the terminal is a shell called wash
. wash
implements a subset of shell
commands (shown below), allowing the user to move around the file system, read
files, and even create new files and write to them!
The code for the filesystem is in filesystem.hpp
and
filesystem.cpp
. The code for wash
is in
wash.hpp
and wash.cpp
. wash
also
utilizes args.hpp
for argument parsing, thanks to @brenfwd
for writing that!
Terminal Emulation:
For terminal mode, we need a terminal! The terminal emulator code is in
terminal_emulator.hpp
and
terminal_emulator.cpp
. This implements an
ANSI escape code-compatible terminal, including 256 color support!
The current list of commands supported are:
clear
pwd
echo <args...>
sleep <time>
cat [file]
cd <path>
ls [path]
The Makefile
chains together all of the necessary build steps.
To build the website, run
$ make
To spin up a server using Python's http.server
, run
