This crate does not ship a C compiler with it. The compiler -required varies per platform, but there are three broad categories: - -* Unix platforms require `cc` to be the C compiler. This can be found by - installing cc/clang on Linux distributions and Xcode on macOS, for example. -* Windows platforms targeting MSVC (e.g. your target triple ends in `-msvc`) - require `cl.exe` to be available and in `PATH`. This is typically found in - standard Visual Studio installations and the `PATH` can be set up by running - the appropriate developer tools shell. -* Windows platforms targeting MinGW (e.g. your target triple ends in `-gnu`) - require `cc` to be available in `PATH`. We recommend the - [MinGW-w64](https://www.mingw-w64.org/) distribution, which is using the - [Win-builds](http://win-builds.org/) installation system. - You may also acquire it via - [MSYS2](https://www.msys2.org/), as explained [here][msys2-help]. Make sure - to install the appropriate architecture corresponding to your installation of - rustc. GCC from older [MinGW](http://www.mingw.org/) project is compatible - only with 32-bit rust compiler. - -[msys2-help]: https://github.com/rust-lang/rust#building-on-windows - -## C++ support - -`cc-rs` supports C++ libraries compilation by using the `cpp` method on -`Build`: - -```rust,no_run -fn main() { - cc::Build::new() - .cpp(true) // Switch to C++ library compilation. - .file("foo.cpp") - .compile("libfoo.a"); -} -``` - -For C++ libraries, the `CXX` and `CXXFLAGS` environment variables are used instead of `CC` and `CFLAGS`. - -The C++ standard library may be linked to the crate target. By default it's `libc++` for macOS, FreeBSD, and OpenBSD, `libc++_shared` for Android, nothing for MSVC, and `libstdc++` for anything else. It can be changed in one of two ways: - -1. by using the `cpp_link_stdlib` method on `Build`: - ```rust,no-run - fn main() { - cc::Build::new() - .cpp(true) - .file("foo.cpp") - .cpp_link_stdlib("stdc++") // use libstdc++ - .compile("libfoo.a"); - } - ``` -2. by setting the `CXXSTDLIB` environment variable. - -In particular, for Android you may want to [use `c++_static` if you have at most one shared library](https://developer.android.com/ndk/guides/cpp-support). - -Remember that C++ does name mangling so `extern "C"` might be required to enable Rust linker to find your functions. - -## CUDA C++ support - -`cc-rs` also supports compiling CUDA C++ libraries by using the `cuda` method -on `Build` (currently for GNU/Clang toolchains only): - -```rust,no_run -fn main() { - cc::Build::new() - // Switch to CUDA C++ library compilation using NVCC. - .cuda(true) - .cudart("static") - // Generate code for Maxwell (GTX 970, 980, 980 Ti, Titan X). - .flag("-gencode").flag("arch=compute_52,code=sm_52") - // Generate code for Maxwell (Jetson TX1). - .flag("-gencode").flag("arch=compute_53,code=sm_53") - // Generate code for Pascal (GTX 1070, 1080, 1080 Ti, Titan Xp). - .flag("-gencode").flag("arch=compute_61,code=sm_61") - // Generate code for Pascal (Tesla P100). - .flag("-gencode").flag("arch=compute_60,code=sm_60") - // Generate code for Pascal (Jetson TX2). - .flag("-gencode").flag("arch=compute_62,code=sm_62") - .file("bar.cu") - .compile("libbar.a"); -} -``` +A library for [Cargo build scripts](https://doc.rust-lang.org/cargo/reference/build-scripts.html) +to compile a set of C/C++/assembly/CUDA files into a static archive for Cargo +to link into the crate being built.

The crate is not limited to C code, it can accept any source code that can -//! be passed to a C or C++ compiler. As such, assembly files with extensions -//! `.s` (gcc/clang) and `.asm` (MSVC) can also be compiled. +//! See [the Rustonomicon](https://doc.rust-lang.org/nomicon/ffi.html) for more details. //! -//! [`Build`]: struct.Build.html +//! # External configuration via environment variables //! -//! # Parallelism +//! To control the programs and flags used for building, the builder can set a +//! number of different environment variables. //! -//! To parallelize computation, enable the `parallel` feature for the crate. +//! * `CFLAGS` - a series of space separated flags passed to compilers. Note that +//! individual flags cannot currently contain spaces, so doing +//! something like: `-L=foo\ bar` is not possible. +//! * `CC` - the actual C compiler used. Note that this is used as an exact +//! executable name, so (for example) no extra flags can be passed inside +//! this variable, and the builder must ensure that there aren't any +//! trailing spaces. This compiler must understand the `-c` flag. For +//! certain `TARGET`s, it also is assumed to know about other flags (most +//! common is `-fPIC`). +//! * `AR` - the `ar` (archiver) executable to use to build the static library. +//! * `CRATE_CC_NO_DEFAULTS` - the default compiler flags may cause conflicts in +//! some cross compiling scenarios. Setting this variable +//! will disable the generation of default compiler +//! flags. +//! * `CC_ENABLE_DEBUG_OUTPUT` - if set, compiler command invocations and exit codes will +//! be logged to stdout. This is useful for debugging build script issues, but can be +//! overly verbose for normal use. +//! * `CXX...` - see [C++ Support](#c-support). +//! +//! Furthermore, projects using this crate may specify custom environment variables +//! to be inspected, for example via the `Build::try_flags_from_environment` +//! function. Consult the project’s own documentation or its use of the `cc` crate +//! for any additional variables it may use. +//! +//! Each of these variables can also be supplied with certain prefixes and suffixes, +//! in the following prioritized order: +//! +//! 1. `<var>_<target>` - for example, `CC_x86_64-unknown-linux-gnu` +//! 2. `<var>_<target_with_underscores>` - for example, `CC_x86_64_unknown_linux_gnu` +//! 3. `<build-kind>_<var>` - for example, `HOST_CC` or `TARGET_CFLAGS` +//! 4. `<var>` - a plain `CC`, `AR` as above. +//! +//! If none of these variables exist, cc-rs uses built-in defaults. +//! +//! In addition to the above optional environment variables, `cc-rs` has some +//! functions with hard requirements on some variables supplied by [cargo's +//! build-script driver][cargo] that it has the `TARGET`, `OUT_DIR`, `OPT_LEVEL`, +//! and `HOST` variables. +//! +//! [cargo]: https://doc.rust-lang.org/cargo/reference/build-scripts.html#inputs-to-the-build-script +//! +//! # Optional features +//! +//! ## Parallel +//! +//! Currently cc-rs supports parallel compilation (think `make -jN`) but this +//! feature is turned off by default. To enable cc-rs to compile C/C++ in parallel, +//! you can change your dependency to: //! //! ```toml //! [build-dependencies] //! cc = { version = "1.0", features = ["parallel"] } //! ``` -//! To specify the max number of concurrent compilation jobs, set the `NUM_JOBS` -//! environment variable to the desired amount. //! -//! Cargo will also set this environment variable when executed with the `-jN` flag. +//! By default cc-rs will limit parallelism to `$NUM_JOBS`, or if not present it +//! will limit it to the number of cpus on the machine. If you are using cargo, +//! use `-jN` option of `build`, `test` and `run` commands as `$NUM_JOBS` +//! is supplied by cargo. +//! +//! # Compile-time Requirements +//! +//! To work properly this crate needs access to a C compiler when the build script +//! is being run. This crate does not ship a C compiler with it. The compiler +//! required varies per platform, but there are three broad categories: //! -//! If `NUM_JOBS` is not set, the `RAYON_NUM_THREADS` environment variable can -//! also specify the build parallelism. +//! * Unix platforms require `cc` to be the C compiler. This can be found by +//! installing cc/clang on Linux distributions and Xcode on macOS, for example. +//! * Windows platforms targeting MSVC (e.g. your target triple ends in `-msvc`) +//! require Visual Studio to be installed. `cc-rs` attempts to locate it, and +//! if it fails, `cl.exe` is expected to be available in `PATH`. This can be +//! set up by running the appropriate developer tools shell. +//! * Windows platforms targeting MinGW (e.g. your target triple ends in `-gnu`) +//! require `cc` to be available in `PATH`. We recommend the +//! [MinGW-w64](https://www.mingw-w64.org/) distribution, which is using the +//! [Win-builds](http://win-builds.org/) installation system. +//! You may also acquire it via +//! [MSYS2](https://www.msys2.org/), as explained [here][msys2-help]. Make sure +//! to install the appropriate architecture corresponding to your installation of +//! rustc. GCC from older [MinGW](http://www.mingw.org/) project is compatible +//! only with 32-bit rust compiler. //! -//! # Examples +//! [msys2-help]: https://github.com/rust-lang/rust#building-on-windows //! -//! Use the `Build` struct to compile `src/foo.c`: +//! # C++ support //! -//! ```no_run +//! `cc-rs` supports C++ libraries compilation by using the `cpp` method on +//! `Build`: +//! +//! ```rust,no_run +//! fn main() { +//! cc::Build::new() +//! .cpp(true) // Switch to C++ library compilation. +//! .file("foo.cpp") +//! .compile("foo"); +//! } +//! ``` +//! +//! For C++ libraries, the `CXX` and `CXXFLAGS` environment variables are used instead of `CC` and `CFLAGS`. +//! +//! The C++ standard library may be linked to the crate target. By default it's `libc++` for macOS, FreeBSD, and OpenBSD, `libc++_shared` for Android, nothing for MSVC, and `libstdc++` for anything else. It can be changed in one of two ways: +//! +//! 1. by using the `cpp_link_stdlib` method on `Build`: +//! ```rust,no_run //! fn main() { //! cc::Build::new() -//! .file("src/foo.c") -//! .define("FOO", Some("bar")) -//! .include("src") +//! .cpp(true) +//! .file("foo.cpp") +//! .cpp_link_stdlib("stdc++") // use libstdc++ //! .compile("foo"); //! } //! ``` +//! 2. by setting the `CXXSTDLIB` environment variable. +//! +//!

Parsing and inspecting Rust literal tokens. +//! +//! This library offers functionality to parse Rust literals, i.e. tokens in the +//! Rust programming language that represent fixed values. The grammar for +//! those is defined [here][ref]. +//! +//! This kind of functionality already exists in the crate `syn`. However, as +//! you oftentimes don't need (nor want) the full power of `syn`, `litrs` was +//! built. This crate also offers a bit more flexibility compared to `syn` +//! (only regarding literals, of course). +//! +//! +//! # Quick start +//! +//! | **`StringLit::try_from(tt)?.value()`** | +//! | - | +//! +//! ... where `tt` is a `proc_macro::TokenTree` and where [`StringLit`] can be +//! replaced with [`Literal`] or other types of literals (e.g. [`FloatLit`]). +//! Calling `value()` returns the value that is represented by the literal. +//! +//! **Mini Example** +//! +//! ```ignore +//! use proc_macro::TokenStream; +//! +//! #[proc_macro] +//! pub fn foo(input: TokenStream) -> TokenStream { +//! let first_token = input.into_iter().next().unwrap(); // Do proper error handling! +//! let string_value = match litrs::StringLit::try_from(first_token) { +//! Ok(string_lit) => string_lit.value(), +//! Err(e) => return e.to_compile_error(), +//! }; +//! +//! // `string_value` is the string value with all escapes resolved. +//! todo!() +//! } +//! ``` +//! +//! # Overview +//! +//! The main types of this library are [`Literal`], representing any kind of +//! literal, and `*Lit`, like [`StringLit`] or [`FloatLit`], representing a +//! specific kind of literal. +//! +//! There are different ways to obtain such a literal type: +//! +//! - **`parse`**: parses a `&str` or `String` and returns `Result<_, +//! ParseError>`. For example: [`Literal::parse`] and +//! [`IntegerLit::parse`]. +//! +//! - **`From<proc_macro::Literal> for Literal`**: turns a `Literal` value from +//! the `proc_macro` crate into a `Literal` from this crate. +//! +//! - **`TryFrom<proc_macro::Literal> for *Lit`**: tries to turn a +//! `proc_macro::Literal` into a specific literal type of this crate. If +//! the input is a literal of a different kind, `Err(InvalidToken)` is +//! returned. +//! +//! - **`TryFrom<proc_macro::TokenTree>`**: attempts to turn a token tree into a +//! literal type of this crate. An error is returned if the token tree is +//! not a literal, or if you are trying to turn it into a specific kind of +//! literal and the token tree is a different kind of literal. +//! +//! All of the `From` and `TryFrom` conversions also work for reference to +//! `proc_macro` types. Additionally, if the crate feature `proc-macro2` is +//! enabled (which it is by default), all these `From` and `TryFrom` impls also +//! exist for the corresponding `proc_macro2` types. +//! +//! **Note**: `true` and `false` are `Ident`s when passed to your proc macro. +//! The `TryFrom<TokenTree>` impls check for those two special idents and +//! return a [`BoolLit`] appropriately. For that reason, there is also no +//! `TryFrom<proc_macro::Literal>` impl for [`BoolLit`]. The `proc_macro::Literal` +//! simply cannot represent bool literals. +//! +//! +//! # Examples +//! +//! In a proc-macro: +//! +//! ```ignore +//! use std::convert::TryFrom; +//! use proc_macro::TokenStream; +//! use litrs::FloatLit; +//! +//! #[proc_macro] +//! pub fn foo(input: TokenStream) -> TokenStream { +//! let mut input = input.into_iter().collect::<Vec<_>>(); +//! if input.len() != 1 { +//! // Please do proper error handling in your real code! +//! panic!("expected exactly one token as input"); +//! } +//! let token = input.remove(0); +//! +//! match FloatLit::try_from(token) { +//! Ok(float_lit) => { /* do something */ } +//! Err(e) => return e.to_compile_error(), +//! } +//! +//! // Dummy output +//! TokenStream::new() +//! } +//! ``` +//! +//! Parsing from string: +//! +//! ``` +//! use litrs::{FloatLit, Literal}; +//! +//! // Parse a specific kind of literal (float in this case): +//! let float_lit = FloatLit::parse("3.14f32"); +//! assert!(float_lit.is_ok()); +//! assert_eq!(float_lit.unwrap().suffix(), "f32"); +//! assert!(FloatLit::parse("'c'").is_err()); +//! +//! // Parse any kind of literal. After parsing, you can inspect the literal +//! // and decide what to do in each case. +//! let lit = Literal::parse("0xff80").expect("failed to parse literal"); +//! match lit { +//! Literal::Integer(lit) => { /* ... */ } +//! Literal::Float(lit) => { /* ... */ } +//! Literal::Bool(lit) => { /* ... */ } +//! Literal::Char(lit) => { /* ... */ } +//! Literal::String(lit) => { /* ... */ } +//! Literal::Byte(lit) => { /* ... */ } +//! Literal::ByteString(lit) => { /* ... */ } +//! } +//! ``` +//! +//! +//! +//! # Crate features +//! +//! - `proc-macro2` (**default**): adds the dependency `proc_macro2`, a bunch of +//! `From` and `TryFrom` impls, and [`InvalidToken::to_compile_error2`]. +//! - `check_suffix`: if enabled, `parse` functions will exactly verify that the +//! literal suffix is valid. Adds the dependency `unicode-xid`. If disabled, +//! only an approximate check (only in ASCII range) is done. If you are +//! writing a proc macro, you don't need to enable this as the suffix is +//! already checked by the compiler. +//! +//! +//!
