Credit syntax definition and theme authors with new `--acknowledgements` option (#1971) 
The text that is printed is generated when building assets, by analyzing LICENSE
and NOTICE files that comes with syntaxes and themes.

We take this opportunity to also add a NOTICE file as defined by Apache License 2.0.

Martin Nordholts e250da8aaa Run `cargo clippy --fix --all-targets --all-features` with Rust 1.57 
Clippy in the newly released Rust 1.57 found some new lints. Conveniently, all
of them were fixable with `--fix`.

Load themes lazily for improved startup time (#1969) 
This is for #951. Syntax lazy-loading will come later and have a much bigger
impact, but lazy-loading of themes does not have negligible impact.

Martin Nordholts 5519f9c716 Use once_cell instead of lazy_static 
once_cell can do what lazy_static does and more, so replace lazy_static with
once_cell.

See https://docs.rs/once_cell/1.8.0/once_cell/#general-purpose-lazy-evaluation

Martin Nordholts dd0925a946 Replace lazycell with once_cell 
We started to use lazycell because syntect already used it. But syntect has
changed to use once_cell. So we should also do that to prepare for using the
upcoming version of syntect.

Martin Nordholts d7671fa8e3 Remove the code related to minimal_syntaxes.bin 
To get fast startup, syntect will instead start to lazy-load syntaxes. See
https://github.com/trishume/syntect/pull/393 and discussions in linked PRs.

Introduce MapExtensionToUnknown MappingTarget (#1889)

Martin Nordholts 4081ace4b9 Include git hash in `bat -V` and `bat --version` output if present 
I had to use a `lazy_static` due to that the clap API that only accepts a
reference to a version string. And, in our code, only a 'static reference to a
version string.

Code could probably be refactored to accept a "normal" reference, but that would
be a major undertaking.

Martin Nordholts aefc8fd824 src/printer.rs: Simplify Plain Text fallback code 
By forwarding the task to find the `Plain Text` syntax to `assets`. Not only does
the code become simpler; we also get rid of a call to `self.get_syntax_set()`
which is beneficial to the long term goal of replacing `syntaxes.bin` with
`minimal_syntaxes.bin`.

Note that the use of `.expect()` is not a regression in error handling. It was
previously hidden in `.find_syntax_plain_text()`.

Martin Nordholts 405a80f3ee HighlightingAssets: Turn get_syntax_for_path() into public API 2021-09-28 07:26:20 +02:00
Martin Nordholts ad98d35a48 HighlightingAssets: Implement get_syntax_for_file_name() with get_syntax_for_path() 
We can do this since the file_name() of a file_name is file_name.

Martin Nordholts 5143f3ad43 build_assets.rs: Add code to track dependents of each syntax 
This information is useful when you want to build several SyntaxSets, but
without having to duplicate SyntaxDefinitions. For example:

"Rust" has no dependencies. But "Markdown" depends on "Rust". With the data
structures this code adds, we know that "Rust" is a dependent syntax for
"Markdown", and can construct a SyntaxSet that takes that into account.

Note that code has a temporary environment flag to ignore any information about
dependents when constructing SyntaxSets. Code that makes use of the new data
structure will be added later.

Martin Nordholts a6dc25a216 build_assets.rs: Make OtherSyntaxLookup come before SyntaxToDependencies

Martin Nordholts f04d2a9d6a build_assets.rs: Rename 'Dependency' to 'OtherSyntax' 
So that we later can use it for not only information about dependencies, but
also for information about dependents.

Martin Nordholts eb3b3b9f8d src/printer.rs: Add HighlighterFromSet helper 
The main benefit is that we get rid of a call to `assets.get_syntax_set()`,
which in turn makes it easier to later get rid of `syntaxes.bin`.

Load independent and minimal syntax sets when using --language (#1787) 
This significantly speeds up the startup time of bat, since only a single
linked SyntaxDefinition is loaded for each file. The size increase of the
binary is just ~400 kB.

In order for startup time to be improved, the --language arg must be used, and
it must match one of the following names:

"Plain Text", "ActionScript", "AppleScript", "Batch File", "NAnt Build File",
"C#", "C", "CSS", "D", "Diff", "Erlang", "Go", "Haskell", "JSON", "Java
Properties", "BibTeX", "LaTeX Log", "TeX", "Lisp", "Lua", "MATLAB", "Pascal",
"R", "Regular Expression", "Rust", "SQL", "Scala", "Tcl", "XML", "YAML", "Apache
Conf", "ARM Assembly", "Assembly (x86_64)", "CMakeCache", "Comma Separated
Values", "Cabal", "CoffeeScript", "CpuInfo", "Dart Analysis Output", "Dart",
"Dockerfile", "DotENV", "F#", "Friendly Interactive Shell (fish)", "Fortran
(Fixed Form)", "Fortran (Modern)", "Fortran Namelist", "fstab", "GLSL",
"GraphQL", "Groff/troff", "group", "hosts", "INI", "Jinja2", "jsonnet",
"Kotlin", "Less", "LLVM", "Lean", "MemInfo", "Nim", "Ninja", "Nix", "passwd",
"PowerShell", "Protocol Buffer (TEXT)", "Puppet", "Rego", "resolv", "Robot
Framework", "SML", "Strace", "Stylus", "Solidity", "Vyper", "Swift",
"SystemVerilog", "TOML", "Terraform", "TypeScript", "TypeScriptReact",
"Verilog", "VimL", "Zig", "gnuplot", "log", "requirements.txt", "Highlight
non-printables", "Private Key", "varlink"

Later commits will improve startup time for more code paths.
