Breaking Changes

• Renamed EmbeddedThemeName::SubmlimeSnazzy -> EmbeddedThemeName::SublimeSnazzy

Features

• Our syntect dependency is now re-exported under two_face::re_exports::syntect
• New syntect-default-onig / syntect-default-fancy features toggle on the underlying default-onig / default-fancy features making the syntect re-export decently useful

Docs

• Both the README and docs landing page got an overhaul
• The theme module got some TLC including a demo of all of the embedded themes
• We now have relevant categories in our Cargo.toml
• Our feature flags are now documented in a way that lib.rs understands

Internal

• Code coverage is now tracked on codecov.io
• Dependabot now handles updating our CI actions
• The unstable feature flag was removed now that syntect-default-onig fills the same purpose in an official capacity
• The specific markdown acknowledgement format was changed to be more succinct
• We now support applying patches on top of those provided with bat including an initial demo stripping comments from Markdown's regexes

Only a couple of very small breaking changes:

• The embedded theme set now includes all of syntect's default themes instead of
  just bat's
• The themes returned by EmbeddedLazyThemeSet::theme_names() are now
  alphabetized

Feature Flags

There are a couple of changes around feature flags:

• All the feature flags revolving around limited which embedded assets get
  pulled in have been ripped out. Luckily the linker is smart enough to strip
  out these unused assets which makes things a lot simpler
• There are new features to indicate which regex implementation you're using
  with syntect. Some syntaxes use features that are only provided by onig
  and not fancy-regex, so matching two-face and syntect's implementation
  keeps regex compilation infallible

Acknowledgments

Acknowledgments now includes the full listing for all syntaxes and themes
regardless of what is used. There are still individual methods to distinquish
which acknowledgments are for what though

Syntaxes

The two_face::syntax::extra() function is now
two_face::syntax::extra_no_newlines() and two_face::extra::extra_newlines()
has been added. This mirrors syntect's load_defaults_nonewlines() and
load_defaults_newlines()

Themes

two_face::theme::extra() now includes an EmbeddedLazyThemeSet. This is just
a wrapper around a LazyThemeSet tailored toward knowing all of the embedded
themes
