[features]
# Filesystem-backed document I/O: `Doc::open`/`save`/`save_as`/`reload` and the
# on-disk change watch (`disk_state`). Default-on, so `leaf-tui` and `leaf-gpui`
# are unaffected. A sandboxed host — wasm in the browser, an FFI embed — builds
# with `--no-default-features` and drives the model through the in-memory
# constructors (`Doc::from_source`, the public `source` field, `mark_saved`)
# instead, since it has no path to read and its own way to persist bytes.
default = ["fs", "syntax"]
fs = []
# Syntax highlighting inside fenced code blocks: each code glyph is classed with
# a `Token` by the language the fence names. Default-on, since every frontend
# paints it, but a feature because of what it weighs — the grammars travel as an
# embedded binary dump of about a megabyte, which a host that has decided a
# wasm bundle or an app binary cannot afford it can leave out. Without it every
# glyph's `token` is `None` and code draws in one colour, as it always did.

# `regex-fancy`, never the default `regex-onig`: oniguruma is a C library, and
# this crate has to keep compiling for `wasm32-unknown-unknown` (leaf-wasm) and
# as a staticlib for iOS (leaf-ffi). `parsing` alone — no `html`, no themes:
# the output is a `Token` per glyph, and the colours are the frontends' own.

# The grammars themselves, as bat packages them, and the same set `plates`
# publishes with. syntect's own bundle is 75 syntaxes and has no Zig, Swift,
# TOML or TypeScript — the first two being what half this organisation is
# written in. two-face carries 213, including all four. `syntect-fancy` rather
# than any `-onig` spelling, for the reason above.
