Changelog

[0.20.1] - 2023-08-06Z

Fixed

Fixed --exclude-atcoder-202301-crates. (#200)

Previously, it was for the "7/3 freeze".

[0.20.0] - 2023-08-06Z

Added

Added --exclude-atcoder-202301-crates. (#197)

        --exclude-atcoder-202301-crates               Alias for `--exclude {crates available on AtCoder 202301}`

Added --toolchain-for-proc-macro-srv. (#195)

        --toolchain-for-proc-macro-srv <TOOLCHAIN>    Toolchain for expanding procedural macros

Changed

Updated the embedded Rust Analyzer to 2023-07-31 (0.0.166). (#195)

For Rust <1.64, --toolchain-for-proc-macro-srv is required for macro expansion.
```
❯ cargo +1.42.0 equip 2>&1 | tail -n 1
  Rust ≧1.64.0 is required for expanding procedural macros. Specify one with `--toolchain-for-proc-macro-srv`
```
This update should fix the issue where macro expansion segfaults.

Renamed --toolchain to --toolchain-for-udeps. (#195)

❯ cargo equip --toolchain nightly
warning: `--toolchain` was renamed to `--toolchain-for-udeps`

cargo-equip now warns for resolver = "2" and edition = "2015". (#196)

Note that both has been unsupported.

warning: Currently cargo-equip only support Feature Resovler v1, and may go search more crates than real Cargo does. Please watch https://github.com/qryxip/cargo-equip/issues/94

warning: Rust 2015 is unsupported

Fixed

Updated prettytable. (#193 by @ichyo)

Now cargo-equip built with recent Rust works.
Adapted the new reserving syntax in Rust 2021 when minifying. (qryxip/rustminify#7 by @mizar, #198).

This fix also affects Rust 2018. The output might be few characters longer.

[0.19.0] - 2022-03-26Z

Added

Ignores workspace members when checking licenses. (#184)

Changed

Embedded rust-analyzer for expanding procedural macros. (#183)

Previously, cargo-equip downloaded rust-analyzer(.exe) from GitHub Releases and used it.
Requires additional 1.48+ toolchain for compiling proc-macro crates when cargo-equip is used for an old toolchain such as 1.42. (#183)

Previously, 1.47 was compatible.

Fixed

Fixed the issue where cargo-equip cannot expand procedural macros for Rust 1.58+. (#183)

[0.18.1] - 2021-12-23Z

Added

(also applied to the previous versions unless --locked) Updated syn to v1.0.83.
- Now accepts some nightly-only syntaxes
- Now accepts trailing + in TypeParamBounds.

Fixed

Now outputs from lib/bin crates are checked without test flag. (#177)

Previously, #[test]s without #[cfg(test)] are unintentionally checked.
Fixed a problem where file paths are not masked in the # License and Copyright Notices section. (#178 by @SGThr7)

[0.18.0] - 2021-09-07Z

Added

Added --mod-path <MODULE_PATH> option. (#159)

+        --mod-path <MODULE_PATH>           Expand the libraries to the module [default: crate::__cargo_equip]

Added --mine <DOMAIN_AND_USERNAME>... option. (#169)

+        --mine <DOMAIN_AND_USERNAME>...
+            Do not include license and copyright notices for the users.
+
+            Supported formats:
+            * github.com/{username}
+            * gitlab.com/{username}

Changed

Enabled running for a lib crate. (#156)

Now you can easily produce standalone Rust source files like my_library.rs.

❯ cargo metadata --format-version 1 | jq -r .resolve.root | awk '{ print $1, $2 }'
proconio 0.4.3
❯ cargo equip --minify libs --remove docs -o ./proconio.rs

Changed potition of the generated doc comment. (#161)

-//! # Bundled libraries
-//! ⋮
 use __cargo_equip::prelude::*;

 fn main() {}
+/// # Bundled libraries
+/// ⋮
 #[allow(unused)]
 mod __cargo_equip {
     // ⋮
 }

cargo-equip no longer uses package.authors to skip Copyright and License Notices. (#164)

Instead, add --mine github.com/your-username to the arguments.
Now uses rust-analyzer 2021-07-12 for Rust 1.47 and 2021-08-09 for Rust 1.48+. (#163)

Fixed

#[macro_export]ed macros will remain in textual scope. (#170)

 #[macro_export]
-macro_rules! hello {
+macro_rules! /*hello*/__cargo_equip_macro_lib_hello {
     () => {
         ::std::println!("Hello!")
     };
 }
+macro_rules!hello{($($tt:tt)*)=>(crate::__cargo_equip_macro_lib_hello!{$($tt)*})}

Improved the minification function. (#153, #157)
```
-let _=| |();
+let _=||();
```
(also applied to the previous versions unless --locked) Updated syn to v1.0.74. (#155)

Now accepts dyn for<'a> Trait<'a>.
Enabled reading license files from git/path package sources. (#156)

Previously cargo-equip reaches a todo!.
Now handles path dependencies correctly when checking an output. (#156, #166)

[0.17.0] - 2021-07-03Z

Changed

Improved the help. (#143)

Now you can read the detailed help with --help while cargo equip -h still prints a short and concise overview.

Changed the format. (#144)

Moved __bundled to __cargo_equip::crates.
Moved __bundled::*::__macros to __cargo_equip::macros.
Now creates __cargo_equip::prelude and glob-uses it instead of declaring __prelude_for_main_crate!.
Unified __bundled::*::{__external_local_inner_macros, __pseudo_extern_prelude} into __cargo_equip::preludes.

//! # Bundled libraries

Updated rust-analyzer to 2021-06-28. (#145)

[0.16.0] - 2021-06-26Z

Changed

--resolve-cfgs --rustfmt --check by default. (#139)

Instead, added --no-resolve-cfgs, --no-rustfmt, and --no-check.

❯ cargo-equip --resolve-cfgs --rustfmt --check
warning: `--resolve-cfgs` is deprecated. `#[cfg(..)]`s are resolved by default

    input! {
        n: usize,
    }
}

Dummy macros are now expanded for proc-macro crates. (#126)

```
use proconio::fastout;

#[fastout]
fn main() {
    println!("Hi");
}
```
Now #[[warn/deny/forbid](missing-(crate-level-)docs)] attributes are removed when --remove docs is enabled. (#126)

watt crate no longer necessary.
rust-analyzer(.exe) is automatically downloaded.
proc-macro crates need to be compile with Rust 1.47.0+. If version of the active toolchain is less than 1.47.0, cargo-equip finds an alternative toolchain and uses it for compiling proc-macros.
procedural macros re-exported with pub use $name::*; are also able to be expanded.

Fixed

Enabled handling non-Meta attribute macros such as #[memoise(n <= 100)].
Fixed a problem where extern crate items in a bin crate are not removed properly.

[0.9.3] - 2021-02-13Z

Fixed

Fixed inability to cargo install cargo-equip without --locked. (#79)

[0.9.2] - 2020-12-23Z

Added

Enabled expanding procedural macros. (#76)

The proc_macro crates need to use watt and have package.metadata like this.

[package.metadata.cargo-equip.watt.proc-macro]
input = "$OUT_DIR/macros_impl.wasm"

[package.metadata.cargo-equip.watt.proc-macro-attribute]
fastout = "$OUT_DIR/macros_impl.wasm"

Example

[dependencies]
qryxip-competitive-fastout = { git = "https://github.com/qryxip/competitive-programming-library" }

#[macro_use]
extern crate fastout as _;

#[fastout]
fn main() {

[0.9.0] - 2020-11-27Z

Added

Added --exclude-atcoder-crates, --exclude-codingame-crates, and --exclude <SPEC>... options. (#68)

        --exclude <SPEC>...           Exclude library crates from bundling
        --exclude-atcoder-crates      Alias for `--exclude https://github.com/rust-lang/crates.io-index#alga:0.9.3 ..`
        --exclude-codingame-crates    Alias for `--exclude https://github.com/rust-lang/crates.io-index#chrono:0.4.9 ..`

Changed

Changed format of the "# Bundled libraries". (#64)

//! # Bundled libraries
//!
//! - `ac-library-rs-parted-internal-math v0.1.0` → `crate::__ac_library_rs_parted_internal_math_0_1_0` (source: `git+https://github.com/qryxip/ac-library-rs-parted#3fc14c009609d8f0a3db8332493dafe457c3460f`, license: `CC0-1.0`)

Now cargo-equip adds "License and copyright notices" to the output when you are using other people's libraries. (#64, #68)

//! # License and Copyright Notices

Currently, only CC0-1.0, Unlicense, MIT and Apache-2.0 are supported.

Now cargo-equip considers platform specific dependencies. (#66)

The 39 crate available on AtCoder are no longer automatically excluded from bundling. (#68)

Enable --exlude-atcoder-crates to exclude them.

note: attempted to bundle with the following crate(s), which are available on AtCoder. to exclude them from bundling, run with `--exclude-atcoder-crates`

- `im-rc 14.3.0 (registry+https://github.com/rust-lang/crates.io-index)`
- `rand_core 0.5.1 (registry+https://github.com/rust-lang/crates.io-index)`

Fixed

extern crate {core, alloc, std}; will be just ignored. (#67)
Replaced -p <libraries>... for cargo check with --bin <binary> when obtaining $OUT_DIRs. (#69)

Previously, cargo check sometimes failed.

[0.8.0] - 2020-11-13Z

Changed

cargo-equip now creates "pseudo extern prelude" in each library. (#60)

Unless you use AIZU ONLINE JUDGE or yukicoder, you no longer need to declare extern crate in libraries.

+mod __pseudo_extern_prelude {
+    pub(super) use crate::{another_lib1, another_lib2};
+}
+use self::__pseudo_extern_prelude::*;
+
 use another_lib1::A;
 use another_lib2::B;

Declaring extern crate .. as .. in a root module will produce a warning. (#58)

To make your libraries compatible with Rust 2015, create a sub module and declare in it.
```
mod extern_crates {
    pub(super) extern crate __another_lib as another_lib;
}

use self::extern_crates::another_lib::foo::Foo;
```
Changed #[allow(dead_code)] to #[allow(unused)]. (#60)

unused is a group of dead-code, unused-imports, and so on.
```
-#[allow(dead_code)]
+#[allow(unused)]
 mod my_lib {
     // ...
 }
```

Fixed

Now libraries are expanded as pub mod. (#58)

 #[allow(unused)]
-mod my_lib {
+pub mod my_lib {
     // ...
 }

[0.7.2] - 2020-11-07Z

Added

Now you can skip the processes except --check. (#48)
```
#![cfg_attr(cargo_equip, cargo_equip::skip)]
```
Enabled expanding code generated in custom-build. (#49)
```
::core::include!(::core::concat!(::core::env!("OUT_DIR", "/generated.rs")));
```
Now you can use qryxip/ac-library-rs-parted with cargo-equip.

Fixed

Fixed the problem where cargo-equip did not treat proc-macro crate as libraries. (#50)

[0.7.1] - 2020-11-07Z

Added

Now it gives pseudo extern_crate_names like "__internal_lib_0_1_0" to dependencies of dependencies. (#43)

You no longer need to include all of the libraries in [dependencies].
Supports extern crate $name as $rename in bins. (#41)
```
extern crate foo as foo_;
```

Fixed

Now it correctly processes outputs of cargo-udeps. (#43)

The names are name_in_tomls. Previously they were treated as extern_crate_names.

[0.7.0] - 2020-11-03Z

Changed

cargo-equip no longer consider modules. (#41)

Split your library into separate small crates.

.
├── input
│   ├── Cargo.lock
│   ├── Cargo.toml
│   └── src
│       └── lib.rs
├── output
│   ├── Cargo.lock
│   ├── Cargo.toml
│   └── src
│       └── lib.rs
⋮

Stopped erasing non mod items just below each lib crates. (#41)
Now cargo-equip inserts pub use crate::{ exported_macros } just below each mod lib_name.
Stopped excluding $ crate :: ident ! parts in macro_rules!. (#41)

Now processes #[macro_use] extern crate $name as _; in bins. (#41)

// in main source code
#[macro_use]
extern crate input as _;

↓

// in main source code
/*#[macro_use]
extern crate input as _;*/

#![cfg_attr(cargo_equip, cargo_equip::equip)] no longer requried. (#41)
```
-#![cfg_attr(cargo_equip, cargo_equip::equip)]
```

#![cfg_attr(cargo_equip, cargo_equip::use_another_lib)] no longer requried. (#41)

-#[cfg_attr(cargo_equip, cargo_equip::use_another_lib)]
 extern crate __another_lib as another_lib;

#![cfg_attr(cargo_equip, cargo_equip::translate_dolalr_crates)] no longer requried. (#41)

-#[cfg_attr(cargo_equip, cargo_equip::translate_dollar_crates)]
 #[macro_export]
 macro_rules! foo { .. }

[0.6.0] - 2020-10-24Z

Added

Added --resolve-cfgs option. (#35)

This option removes:
1. #[cfg(always_true_condition)] (e.g. cfg(feature = "enabled-feature"))
2. Items with #[cfg(always_false_condition)] (e.g. cfg(test), cfg(feature = "disable-feature"))

Removed

Removed --remove test-items option. (#35)

Use --resolve-cfgs instead.

[0.5.3] - 2020-10-24Z

Fixed

Fixed the minification function. (#33)

Previously, x < -y was converted into x<-y.

[0.5.2] - 2020-10-22Z

Added

Improved the minification function. (#31)

[0.5.1] - 2020-10-17Z

Added

Now cargo-equip replaces crate path prefixes in library code with crate::extern_crate_name_in_main_crate. (#29)

[0.5.0] - 2020-10-03Z

Changed

Changed the process of bundling. (#27)

Now cargo-equip "expands" each mods in lib.rs, remove unused ones, then minify the code by lib.
#[cfg_attr(cargo_equip, cargo_equip::equip)] now targets root modules instead of use statements. (#27)

All of the use statements in the crate root that start with :: are expanded.
```
#![cfg_attr(cargo_equip, cargo_equip::equip)]

use ::__foo::{a::A, b::B};
use ::__bar::{c::C, d::D};
```
Renamed --minify mods to --minify libs. (#27)

[0.4.1] - 2020-09-28Z

Added

Enabled writing package.metadata.cargo-equip.module-dependencies also in libraries. (#25)

They are merged into one graph.

[package.metadata.cargo-equip.module-dependencies]
"crate::a" = []
"crate::b" = ["crate::b"]
"crate::c" = ["::__another_lib::d"]
"::__another_lib::d" = ["::__another_lib::e"]

[0.4.0] - 2020-09-27Z

Added

Now cargo-equip supports libraries that depend on each other. (#23)

Statements like this will be converted to use crate::..;.
```
#[cfg_attr(cargo_equip, cargo_equip::use_another_lib)]
extern crate __another_lib as another_lib;
```

Changed

Each library will be expanded in mod. (#23)

More constraints were introduced. See README-ja for more details.

#[allow(dead_code)]
pub mod __lib {
    pub mod a {}
    pub mod b {}
    pub mod c {}
}

cargo-equip will use [package.metadata.cargo-equip.module-dependencies] in the main crate. (#23)

Package metadata in libraries is no longer read.

And the format was also changed.

[package.metadata.cargo-equip.module-dependencies]
"::__atcoder::convolution" = ["::__atcoder::internal_bit", "::__atcoder::modint"]
"::__atcoder::internal_bit" = []
"::__atcoder::internal_math" = []
"::__atcoder::internal_queue" = []
"::__atcoder::internal_scc" = []
"::__atcoder::internal_type_traits" = []
"::__atcoder::lazysegtree" = ["::__atcoder::internal_bit", "::__atcoder::segtree"]
"::__atcoder::math" = ["::__atcoder::internal_math"]
"::__atcoder::maxflow" = ["::__atcoder::internal_type_traits", "::__atcoder::internal_queue"]
"::__atcoder::mincostflow" = ["::__atcoder::internal_type_traits"]
"::__atcoder::modint" = ["::__atcoder::internal_math"]
"::__atcoder::scc" = ["::__atcoder::internal_scc"]
"::__atcoder::segtree" = ["::__atcoder::internal_bit", "::__atcoder::internal_type_traits"]
"::__atcoder::twosat" = ["::__atcoder::internal_scc"]

Renamed --oneline option to --minify. --oneline remains as an alias for --minify. (#21)

With --minify option, cargo-equip removes spaces as much as possible.

#[allow(clippy::deprecated_cfg_attr)]#[cfg_attr(rustfmt,rustfmt::skip)]pub mod factorial{pub fn factorial(n:u64)->u64{match n{0=>1,n=>n*factorial(n-1),}}}

[0.3.4] - 2020-09-21Z

Fixed

Fixed the problem where --remove comments ruined code that contains tuple types. (#19)

[0.3.3] - 2020-09-19Z

Fixed

--remove option now works for code that contains non-ASCII characters. (#16)

[0.3.2] - 2020-09-17Z

Added

Added --remove option. (#13)

Now you can remove

Items with #[cfg(test)]
Doc comments (//! .., /// .., /** .. */, #[doc = ".."])
Comments (// .., /* .. */)

from the output.

pub mod a {
    //! A.

    /// A.
    pub struct A; // aaaaa

    #[cfg(test)]
    mod tests {
        #[test]
        fn it_works() {
            assert_eq!(2 + 2, 4);
        }
    }
}

↓

pub mod a {
    pub struct A;
}

[0.3.1] - 2020-09-15Z

Added

Enabled bundling multiple libraries.

#[cfg_attr(cargo_equip, cargo_equip::equip)]
use ::{
    __lib1::{a::A, b::B, c::C},
    __lib2::{d::D, e::E, f::F},
};

[0.3.0] - 2020-09-03Z

Added

cargo_equip_marker is no longer required.

#[cfg_attr(cargo_equip, cargo_equip::equip)]
use ::__my_lib::{a::A, b::B, c::C};

Changed

Appends the "# Bundled libralies" section to existing doc comment.
Changed the format of "# Bundled libralies".

[0.2.0] - 2020-09-02Z

Changed

Now it includes the used module list in the output.

Fixed

--check option will work with { path = ".." } dependencies.
