This allows the project to be built using `nix build` and run
using `nix run`.
The basis for this is @srid's work in #11707, with some
simplifications and improvements added on.
stack.yaml is used as a source of truth for the versions to use,
including for git repositories.
Closes#11707.
'make pandoc.wasm' will compile a wasm version of pandoc.
This also adds a 'repl' flag to pandoc-lua-engine, so that
support for a Lua repl can be disabled for the wasm build.
A new wasm directory contains:
- pandoc.js, a JavaScript wrapper for pandoc.wasm
- index.html + index.js, a web app exposing all of pandoc's
functionality in a GUI interface
- a set of illustrative examples that can be loaded from the web app
Most of the code in index.html and index.js has been produced in
interaction with Claude code.
We don't need the workarounds any more.
We no longer include pandoc-cli, pandoc-server, or pandoc-lua-engine
in the packages. Instead, add some of the heavier dependencies to
the list of build inputs.
This is at least a temporary solution to #8818.
