Experiment: remove CARGO_TEST_OPTIONS

In principle, this *could* work. `cargo cross` runs the tests via QEMU.
For integration tests, the only difficulty is that we run `bat` from
within the tests. But maybe this is handled by assert_cmd.

 # unreleased
 
+## Features
+
+- `$BAT_CONFIG_DIR` is now a recognized environment variable. It has precedence over `$XDG_CONFIG_HOME`, see #1727 (@billrisher)
+
+## Bugfixes
+
+- Python syntax highlighting no longer suffers from abysmal performance in specific scenarios. See #1688 (@keith-hall)
+
+## Other
+
+- Load cached assets as fast as integrated assets, see #1753 (@Enselic)
+- Greatly reduce startup time in loop-through mode, e.g. when redirecting output. Instead of *50 ms* - *100 ms*, startup takes *5 ms* - *10 ms*. See #1747 (@Enselic)
+
+
+## Syntaxes
+
+- Groff, see #1685 (@scop)
+- HTTP Requests and Responses, see #1748 (@keith-hall)
+- LLVM, see #1777 (@ioncodes)
+- Highlight for `vimrc` and `gvimrc` files, see #1763 (@SuperSandro2000)
+- Syslog highlighting improvements, see #1793 (@scop)
+- Added support for `slim` syntax, see #1693 (@mfinelli)
+
+## New themes
+
+
+## `bat` as a library
+
+- Deprecate `HighlightingAssets::syntaxes()` and `HighlightingAssets::syntax_for_file_name()`. Use `HighlightingAssets::get_syntaxes()` and `HighlightingAssets::get_syntax_for_file_name()` instead. They return a `Result` which is needed for upcoming lazy-loading work to improve startup performance. They also return what `SyntaxSet` the returned `SyntaxReference` belongs to. See #1747, #1755 and #1776 (@Enselic)
+
+
+
+# v0.18.2
+
+## Features
+
+- Ignore known backup/template filename suffixes when selecting the syntax, see #1687 (@scop)
+
+## Bugfixes
+
+- Fix for a security vulnerability on Windows. Prior to this release, `bat` would execute programs called `less`/`less.exe` from the current working directory (instead of the one from `PATH`) with priority. An attacker might be able to use this by placing a malicious program in a shared directory where the user would execute `bat`. `bat` users on Windows are advised to upgrade to this version. See #1724 and #1472 (@Ry0taK).
+
+## Other
+
+- Add bash completion, see #1678 (@scop)
+- Fix Clippy lints, see #1661 (@mohamed-abdelnour)
+- Add syntax highlighting test files, see #1213 and #1668 (@mohamed-abdelnour)
+
+## Syntaxes
+
+- Upgraded Julia syntax to fix a highlighting bug, see #1692
+- Added support for `dash` syntax, see #1654 (@mohamed-abdelnour)
+- Added support for `XAML` syntax, see #1590 and #1655 (@mohamed-abdelnour)
+- Apply `DotENV` syntax also for `.env.default` and `.env.defaults` files, see #1669
+
+
+# v0.18.1
+
+## Bugfixes
+
+- Mouse support and screen clearing broken for `less` versions with minor version number (581.2), see #1629 and #1639 (@aswild)
+
+## Other
+
+- `Input::ordinary_file` and `Input::with_name` now accept `Path` rather than `OsStr` see #1571 (@matklad)
+- The `LESS` environment variable is now included in `bat --diagnostic`, see #1589 (@Enselic)
+- Increased min. required Rust version to 1.45
+
+## Syntaxes
+
+- Improved the Syslog syntax highlighting, see #1606 (@keith-hall)
+- Replaced "Advanced CSV" with a custom CSV syntax definition written especially for `bat`; see #1574 (@keith-hall)
+- Added SystemVerilog file syntax, see #1580 (@SeanMcLoughlin)
+- Added Solidity and Vyper syntax, see #1602 (@Ersikan)

+
+### 8비트 테마
+
+`bat`은 트루컬러 지원이 되더라도 항상
+[8비트 색상](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors)을 사용하는
+세 개의 테마가 있습니다.
+
+- `ansi`는 어떤 터미널에서도 무난하게 보입니다. 이는 3비트 색상을 사용합니다:
+  검정, 빨강, 녹색, 노랑, 파랑, 마젠타, 시안, 하양.
+- `base16`은 [base16](https://github.com/chriskempson/base16) 터미널 테마를 위해
+  디자인되었습니다.
+  이는 [base16 스타일 가이드라인](https://github.com/chriskempson/base16/blob/master/styling.md)에
+  따라 4비트 색상(3비트 색상에 밝은 변형 추가)을 사용합니다.
+- `base16-256`는 [base16-shell](https://github.com/chriskempson/base16-shell)을
+  위해 디자인되었습니다.
+  이는 16부터 21의 일부 밝은 색상을 8비트 색상으로 대치합니다.
+  단지 256-색상 터미널을 쓰지만 base16-shell을 쓰지 않는다고 해서 이것을
+  사용하지 **마십시오**.
+
+이들 테마는 더 제한적이지만, 트루컬러 테마에 비해 두 장점이 있습니다:
+
+- 이들은 3비트 혹은 4비트 색상을 쓰는 다른 터미널 소프트웨어와 더 잘
+  어울립니다.
+- 만약 터미널 테마를 바꾼다면, 이미 화면 상의 `bat`의 출력도 이에 맞추어
+  업데이트됩니다.
 
 ### 출력 스타일
 
-`--style` 옵션을 이용하여 `bat`의 출력 스타일을 변경 할 수 있습니다. 예를 들어,  `--style=numbers,changes`는 Git 변경분과 라인 넘버에 대해서만 출력하며 눈금과 파일 헤더가 표시되지 않습니다. `BAT_STYLE` 환경 변수로 정의하여 계속해서 사용하거나`bat`의 [설정 파일](#설정-파일)을 사용할 수도 있습니다.
+`--style` 옵션을 이용하면 `bat`의 출력 모양을 조절할 수 있습니다.
+예를 들어, `--style=numbers,changes`를 통해 Git 변경분과 줄 번호는 출력하지만
+격자와 파일 헤더는 출력하지 않을 수 있습니다.
+`BAT_STYLE` 환경 변수를 정의하여 이러한 수정을 영구적으로 하거나 `bat`의
+[설정 파일](#설정-파일)을 사용하세요.
 
-### 새로운 문법 강조 / 언어 추가하기
+### 새로운 문법 / 언어 정의 추가하기
 
-`bat`은 문법 강조를 위해 [`syntect`](https://github.com/trishume/syntect/) 라이브러리를 사용하고 있습니다.  `syntect`는 [Sublime Text의 `.sublime-syntax` 파일](https://www.sublimetext.com/docs/3/syntax.html)과 테마를 읽을 수 있습니다. 새로운 문법 강조를 추가하는 방법은 다음과 같습니다. 
+만약 `bat`에서 특정 문법이 지원되지 않을 경우, 다음의 절차를 통해 현재 `bat`
+설치본에 새로운 문법을 쉽게 추가할 수 있습니다.
 
-우선 문법 정의 파일을 넣을 폴더를 만듭니다:
+`bat`은 문법 강조를 위해 훌륭한
+[`syntect`](https://github.com/trishume/syntect/) 라이브러리를 사용합니다.

+파일](https://www.sublimetext.com/docs/3/syntax.html)과 테마를 읽을 수 있습니다.
 
-```bash
-mkdir -p "$(bat --config-dir)/syntaxes"
-cd "$(bat --config-dir)/syntaxes"
+[Package Control](https://packagecontrol.io/)에 Sublime 문법 패키지를 찾는
+방법이 잘 정리되어 있습니다.
+일단 문법을 찾았다면:
 
-# Put new '.sublime-syntax' language definition files
-# in this folder (or its subdirectories), for example:
-git clone https://github.com/tellnobody1/sublime-purescript-syntax
-```
+1. 문법 정의 파일들을 넣을 폴더를 만듭니다:
 
-다음 명령어를 통해 파일을 바이너리 캐시로 파싱합니다. 
+  ```bash
+  mkdir -p "$(bat --config-dir)/syntaxes"
+  cd "$(bat --config-dir)/syntaxes"
 
-```bash
-bat cache --build
-```
+  # Put new '.sublime-syntax' language definition files
+  # in this folder (or its subdirectories), for example:
+  git clone https://github.com/tellnobody1/sublime-purescript-syntax
+  ```
 
-마지막으로 `bat --list-languages`을 통해 새로운 언어가 사용 가능한지 확인합니다. 
+2. 이제 다음 명령어를 통해 파일들을 파싱(parse)하여 바이너리 캐시를 만듭니다.
 
-기본 설정으로 돌아가려면, 다음 명령어를 이용합니다.:
+  ```bash
+  bat cache --build
+  ```
 
-```bash
-bat cache --clear
-```
+3. 마지막으로, `bat --list-languages`로 새로 추가한 언어가 사용 가능한지
+  확인합니다.
+
+  만약 기본 설정으로 돌아갈 일이 생긴다면, 다음 명령어를 이용합니다:
+
+  ```bash
+  bat cache --clear
+  ```
+
+4. 만약 특정 문법이 `bat`에 기본적으로 포함되어 있어야 한다고 생각한다면, 방침과
+  절차를 [여기](../doc/assets.md)서 읽은 후 "문법 요청(syntax request)"을 열어
+  주세요: [문법 요청하기](https://github.com/sharkdp/bat/issues/new?labels=syntax-request&template=syntax_request.md).

-### 다른 페이져 사용하기
+### 파일 타입 설정을 추가하거나 변경하기
 
-`bat`은 환경변수 `PAGER`로 사용할 페이져를 명시합니다. 만약 이 변수가 정의되어있지 않다면 `less`가 기본입니다. 만약 다른 페이져를 사용하고 싶다면 `PAGER` 변수를 수정하거나 `BAT_PAGER` 환경 변수로 `PAGER` 대신 정의 할 수도 있습니다. 
+새로운 파일 이름 패턴을 추가하려면 (혹은 이미 존재하는 것을 변경하려면)
+`--map-syntax` 커맨드 라인 옵션을 사용하세요.
+이 옵션은 `pattern:syntax` 꼴의 인자를 받습니다.
+이때 `pattern`은 파일 이름과 절대 파일 경로를 매치할 글로브(glob) 패턴입니다.
+`syntax` 부분은 지원되는 언어의 전체 이름입니다
+(`bat --list-languages`를 통해 개요를 확인하세요).
 
-만약 커맨드라인 인수로 넘기려면, `PAGER`/`BAT_PAGER` 변수를 정의를 통해 사용 할 수 있습니다. :
+참고: 이 옵션은 커맨드 라인에 넘겨 주는 것보다는 `bat`의 설정 파일에 넣는 것이
+좋을 것입니다 (아래를 보세요).
+
+예시: "INI" 문법 강조를 `.conf` 파일 확장자의 모든 파일에 적용하려면, 다음을
+사용하세요:
+```bash
+--map-syntax='*.conf:INI'
+```
+
+예시: `.ignore`(완전 일치)이라는 이름의 모든 파일을 "Git Ignore" 문법으로
+열려면, 다음을 사용하세요:
+```bash
+--map-syntax='.ignore:Git Ignore'
+```
+
+예시: `/etc/apache2`의 하위 폴더들에 있는 모든 `.conf` 파일들을 "Apache Conf"
+문법으로 열려면, 다음을 사용하세요 (이 대응(mapping)은 이미 내장되어 있습니다):
+```bash
+--map-syntax='/etc/apache2/**/*.conf:Apache Conf'
+```
+
+### 다른 페이저 사용하기
+
+`bat`은 환경 변수 `PAGER`에 명시된 페이저를 사용합니다.
+이 변수가 정의되어 있지 않다면, `less`가 기본으로 사용됩니다.
+만약 다른 페이저를 사용하고 싶다면, `PAGER` 변수를 수정하거나 `BAT_PAGER` 환경
+변수를 설정하여 `PAGER`의 설정을 오버라이드(override)할 수 있습니다.
+
+만약 커맨드라인 인수들을 페이저에게 넘겨 주려면, `PAGER`/`BAT_PAGER` 변수로
+설정할 수 있습니다:
 
 ```bash
 export BAT_PAGER="less -RF"
 ```
 
-환경 변수 대신, `bat`의 [설정 파일](#설정-파일)에서 페이져를 설정 할 수도 있습니다.(`--pager` 옵션)
+환경 변수를 사용하는 대신, `bat`의 [설정 파일](#설정-파일)로 페이저를 설정할
+수도 있습니다 (`--pager` 옵션).
 
-**참고**: 기본적으로 페이져가 `less`로 설정 되어있다면, `bat`은 다음 옵션들을 받을 수 있습니다: `-R`/`--RAW-CONTROL-CHARS`,
-`-F`/`--quit-if-one-screen` 그리고 `-X`/`--no-init`. 마지막 옵션(`-X`)은 530 이전 버전에서만 사용됩니다. 
+**참고**: 기본적으로, 페이저가 `less`로 설정되어 있다면 (그리고 커맨드 라인
+옵션이 지정되어 있지 않다면), `bat`은 다음 옵션들을 페이저로 넘겨줍니다:
+`-R`/`--RAW-CONTROL-CHARS`, `-F`/`--quit-if-one-screen` 그리고 `-X`/`--no-init`.
+마지막 옵션(`-X`)은 530 이전 버전의 `less`에만 사용됩니다.
 
-`-R` 옵션은 ANSI 컬러를 올바르게 해석하기 위해 필요합니다. 두번째 옵션 (`-F`)은 출력 크기가 터미널의 세로 크기보다 작을 경우 즉시 종료되도록 합니다. 
-페이져를 종료하기 위해 `q`를 누를 필요 없기 때문에 작은 파일을 다룰 때 용이합니다. 세번째 옵션(`-X`)는 `less` 이전 버전의 `--quit-if-one-screen` 기능과 함께 버그를 잡을 때 필요합니다. 안타깝게도, `less`의 마우스 휠 지원은 종료합니다. 
+`-R` 옵션은 ANSI 색상을 올바르게 해석하기 위해 필요합니다.
+두 번째 옵션(`-F`)은 출력 크기가 터미널의 세로 크기보다 작을 경우 less가 즉시

+이는 작은 파일을 다룰 때 페이저를 종료하기 위해 `q`를 누를 필요 없어서
+편리합니다.
+세 번째 옵션(`-X`)는 예전 버전의 `less`에 있는 `--quit-if-one-screen` 기능의
+버그를 고치기 위해 필요합니다.
+안타깝게도, 이는 `less`의 마우스 휠 지원과 호환되지 않습니다.
 
-`less` 예전 버전에서 마우스 휠 기능을 활성화 시키려면, `-R` 옵션을 사용하면 됩니다. (위의 예제처럼, 이 옵션은 quit-if-one-screen  기능을 비활성화 시킵니다.)
-530 이하 버전에서는 그대로 사용할 수 있습니다.

+(위의 예제처럼, 이 옵션은 quit-if-one-screen 기능을 비활성화합니다).
+less 530과 이후 버전에서는 그대로 사용할 수 있습니다.
+
+### 들여쓰기
+
+`bat`은 페이저에 의존하지 않고 탭을 4 스페이스로 확장합니다.
+이를 변경하려면 간단히 `--tabs` 인자에 표시되기를 원하는 스페이스 개수를
+추가하세요.
+
+**참고**: (`bat`의 `--pager` 인자 혹은 `less`의 `LESS` 환경 변수를 통해)
+페이저의 탭 길이를 지정하는 것은 효과가 없을 것인데, 이는 페이저가 이미
+스페이스로 확장된 탭을 받기 때문입니다.
+이 기능은 사이드바에 의한 들여쓰기 문제를 회피하기 위해 추가되었습니다.
+`bat`을 `--tabs=0`과 함께 호출하면 이를 오버라이드하여 페이저가 탭을 처리하게
+합니다.

-`bat`은 터미널 트루컬러 지원 여부와 상관없이 동작합니다. 하지만, 문법 강조 테마의 색상이 8-bit 컬러에는 최적화 되어 있지 않고 있으며, 24-bit 트루컬러 지원하는 터미널 사용하는 것을 적극 권장합니다.(`terminator`, `konsole`, `iTerm2`, ...). [이 글](https://gist.github.com/XVilka/8346728)에서 24-bit 트루컬러 지원하는 터미널들을 찾아보실 수 있습니다.

 ### 파일 인코딩
 
-`bat`은 기본적으로 UTF-8과 UTF-8을 제공합니다. 다른 파일 인코딩의 경우, 자동 감지 되지 않으므로 UTF-8로 먼저 변환해 주어야 합니다. 이렇게 할 때, `iconv`를 사용 할 수 있습니다. 예를 들어,  Latin-1 (ISO-8859-1)로 인코딩된 PHP파일이라면 다음과 같이 사용할 수 있습니다.:

+# Release checklist
+
+## Dependencies
+
+See this page for a good overview: https://deps.rs/repo/github/sharkdp/bat
+
+- [ ] Optional: update dependencies with `cargo update`. This is also done by
+      dependabot, so it is not strictly necessary.
+- [ ] Check for outdated dependencies (`cargo outdated`) and decide for each of
+      them whether we want to (manually) upgrade. This will require changes to
+      `Cargo.toml`.
+
+## Version bump
+
+- [ ] Update version in `Cargo.toml`. Run `cargo build` to update `Cargo.lock`.
+      Make sure to `git add` the `Cargo.lock` changes as well.
+- [ ] Find the current min. supported Rust version by running
+      `grep '^\s*MIN_SUPPORTED_RUST_VERSION' .github/workflows/CICD.yml`.
+- [ ] Update the version and the min. supported Rust version in `README.md` and
+      `doc/README-*.md`.
+- [ ] Update `CHANGELOG.md`. Introduce a section for the new release and
+      prepare a new (empty) "unreleased" section at the top.
+
+## Update syntaxes and themes (build assets)
+
+- [ ] Install the latest master version (`cargo install -f --path .`) and make
+      sure that it is available on the `PATH` (`bat --version` should show the
+      new version).
+- [ ] Run `assets/create.sh` and check in the binary asset files.
+
+## Documentation
+
+- [ ] Review the `-h` and `--help` texts
+- [ ] Review the `man` page
+
+## Pre-release checks
+
+- [ ] Push all changes and wait for CI to succeed (before continuing with the
+      next section).
+- [ ] Optional: manually test the new features and command-line options. To do
+      this, install the latest `bat` version again (to include the new synaxes
+      and themes).
+- [ ] Run `cargo publish --dry-run --allow-dirty` to make sure that it will
+      succeed later (after creating the GitHub release).
+
+## Release
+
+- [ ] Create a tag and push it to the remote `git tag vX.Y.Z; git push --tags`.
+      This will trigger the deployment via GitHub Actions.
+- [ ] Go to https://github.com/sharkdp/bat/releases/new to create the new
+      release. Select the new tag and also use it as the release title. For the
+      release notes, copy the corresponding section from `CHANGELOG.md` and
+      possibly add additional remarks for package maintainers.
+      Publish the release.
+- [ ] Check if the binary deployment works (archives and Debian packages should
+      appear when the CI run for the Git tag has finished).
+- [ ] Publish to crates.io by running `cargo publish` in a *clean* repository.
+      The safest way to do this is to clone a fresh copy.

+C  Fortran 77 implementation of a quicksort algorithm for arrays with
+C  real entries.
+C  ----------
+C  June 2019 
+C  Jason Allen Anema, Ph.D.
+C  Division of Statistical Genomics
+C  Department of Genetics
+C  Washington University School of Medicine in St. Louis

+C  This work is partially supported NIH grant AG023746
+C  ----------
+C  Insertion sort is used for short arrays, as quicksort is slower on
+C  these.
+C  
+C  Hoare partition scheme is used (sweeping left and right), as it does
+C  three times fewer swaps on average that the Lamuto partition scheme.
+C  In conjunction with this, tripartite partition is performed
+C  concurrently (solving the "Dutch National Flag problem"). This avoids 
+C  horrible runtimes on highly repetitive arrays. For example, without  
+C  this, an array of random zeros and ones would have a runtime of
+C  O(N^2), but now has a runtime of O(N). The runtime for this algorthm
+C  on arrays with k highly repetitive entries is now O(kN).
+C    
+C  For medium length (sub)arrays, pivots are choosen using
+C  Median-of-Three, and those three items are sorted. For longer (sub)arrays
+C  the pseudomedian of nine (Median of medians). This avoids O(N^2) runtime on
+C  nonrandom inputs such as increasing and decreasing sequences. 
+C
+C  See Louis Bentley, Jon & McIlroy, Douglas. (1993). Engineering a Sort Function.
+C  Softw., Pract. Exper.. 23. 1249-1265. 10.1002/spe.4380231105 for details. 
+C
+C  The ordering on elements of the array are defined by a comparison
+C  function,compar, that is a user-supplied INTEGER*2 function of the form
+C           compar(a,b) which returns:
+C              -1 if a precedes b
+C              +1 if b precedes a
+C              0 is a and b are considered equivalent
+C  and thus defines a total ordering.
+C  
+C  If one would like to use the standard order on integers, the
+C  compar function could be written in a file "compint.F" as:
+C  ----------------------------------------------------------------
+C      INTEGER*2 FUNCTION compint(a,b)
+C      INTEGER a, b
+C      if(a.lt.b)then
+C         compint = -1
+C      elseif(a.gt.b)then
+C         compint = +1
+C      else
+C         compint = 0
+C      endif
+C      END
+C  ----------------------------------------------------------------
+C  Then in your program, call quicksort with:
+C      call quicksort_real_F77(array, n, compint)
+C
+C  The maximal length of an array in this implementation is (2^31-1),
+C  but can be changed to allow for length up to (2^63-1) by changing the
+C  data types of the relevant variables and constants. If you wish to 
+C  sort longer arrays, of length N, you'll need to customize variable 
+C  and constant types and set mstack to be at least (2*log_2(N)+2).

+C        maxins: maximal size of (sub)arrays to be sorted with
+C           insertion sort.
+C        maxmid: maximal size of (sub)arrays that will be quicksorted with
+C           Median-of-Three pivots.
+C        mstack: maximal size of required auxiliary storage (a stack), plus 2 
+C           extra spots, which tracks the starts and ends of yet unsorted 
+C           subarrays. mstack = 130 is large enough to handle arrays up to 
+C           length 2^63-1. This maximal size follows from
+C           processing smaller arrays first and pigeonhole principal.

+.SH "OUTPUT FORMATS"
+
+The rustdoc tool can generate output in an HTML format.
+
+If using an HTML format, then the specified output destination will be the root
+directory of an HTML structure for all the documentation.
+Pages will be placed into this directory, and source files will also
+possibly be rendered into it as well.
+
+.SH "EXAMPLES"
+
+To generate documentation for the source in the current directory:
+    $ rustdoc hello.rs
+
+List all available passes that rustdoc has, along with default passes:
+    $ rustdoc \-\-passes list
+
+The generated HTML can be viewed with any standard web browser.
