'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.
Functions that expect UTF-8-encoded filenames should make it easier to
write platform-independent scripts, as the encoding of the actual
filename depends on the system.
Additionally, this also adds a generalized method to run commands, and
functions to retrieve XDG directory names.
The new functions are `command`, `copy`, `read_file`, `remove`,
`rename`, `times`, `write_file`, `xdg`.
Pandoc already depends on `crypton-conntection`, and thus transitively
on `crypton`. The latter provides a vast variety of hashing algorithms
and makes the dependency on SHA unnecessary.
The `Doc` values produced and handled by the `pandoc.layout` module can
now be styled using `bold`, `italic`, `underlined`, or `strikeout`. The
style is ignored in normal rendering, but becomes visible when rendering
to ANSI output. The `pandoc.layout.render` function now takes a third
parameter that defines the output style, either *plain* or *ansi*.
The module now comes with a method `:at(index[, def])` that allows to access
indices, accepts negative indices to count from the end, and will return the
`def` value as a default if the list has no item at the given position.
Furthermore, the list constructor `pandoc.List` now accepts iterators. E.g.,
`pandoc.List(text:gmatch '%S+')` returns the list of words in `text`.
Closes: #9835
