+- Deprecate `HighlightingAssets::syntaxes()` and `HighlightingAssets::syntax_for_file_name()`. Use `HighlightingAssets::get_syntaxes()` and `HighlightingAssets::get_syntax_for_path()` instead. They return a `Result` which is needed for upcoming lazy-loading work to improve startup performance. They also return which `SyntaxSet` the returned `SyntaxReference` belongs to. See #1747, #1755, #1776, #1862 (@Enselic)
+- Remove `HighlightingAssets::from_files` and `HighlightingAssets::save_to_cache`. Instead of calling the former and then the latter you now make a single call to `bat::assets::build`. See #1802, #1971 (@Enselic)
+- Replace  the `error::Error(error::ErrorKind, _)` struct and enum with an `error::Error` enum. `Error(ErrorKind::UnknownSyntax, _)` becomes `Error::UnknownSyntax`, etc. Also remove the `error::ResultExt` trait. These changes stem from replacing `error-chain` with `thiserror`. See #1820 (@Enselic)
+- Add new `MappingTarget` enum variant `MapExtensionToUnknown`. Refer to its documentation for more information. Also mark `MappingTarget` as `#[non_exhaustive]` since more enum variants might be added in the future. See #1703 (@cbolgiano), #2012 (@Enselic)

+- 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.

+
+You are strongly encouraged to add regression tests. Regression tests are great,
+not least because they:
+
+* ensure that your contribution will never completely stop working,
+
+* makes code review easier, because it becomes very clear what the code is

+
+For functional changes, you most likely want to add a test to

+Look at existing tests to know how to write a new test. In short, you will

 ## Troubleshooting

+### Garbled output
+
+If an input file contains color codes or other ANSI escape sequences or control characters, `bat` will have problems

 Determine which pager is used. This option will override the PAGER and BAT_PAGER

 the '\-\-paging' option. Example: '\-\-pager "less \fB\-RF\fR"'.
+
+Note: By default, if the pager is set to 'less' (and no command-line options are specified), 'bat' will pass the following command line options to the pager: '-R'/'--RAW-CONTROL-CHARS', '-F'/'--quit-if-one-screen' and '-X'/'--no-init'. The last option ('-X') is only used for 'less' versions older than 530. The '-R' option is needed to interpret ANSI colors correctly. The second option ('-F') instructs less to exit immediately if the output size is smaller than the vertical size of the terminal. This is convenient for small files because you do not have to press 'q' to quit the pager. The third option ('-X') is needed to fix a bug with the '--quit-if-one-screen' feature in old versions of 'less'. Unfortunately, it also breaks mouse-wheel support in 'less'. If you want to enable mouse-wheel scrolling on older versions of 'less', you can pass just '-R' (as in the example above, this will disable the quit-if-one-screen feature). For less 530 or newer, it should work out of the box.

+</p>
+
+### 语法高亮
+
+`bat` 对大部分编程语言和标记语言提供语法高亮：
+
+![Syntax highlighting example](https://imgur.com/rGsdnDe.png)
+
+### Git 集成
+
+`bat` 能从 git 中获取文件的修改并展示在边栏（见下图）：
+
+![Git integration example](https://i.imgur.com/2lSW4RE.png)
+
+### 不可打印(non-printable)字符可视化
+
+添加`-A`/`--show-all`参数可以文件文件中的不可打印字符:
+
+![Non-printable character example](https://i.imgur.com/WndGp9H.png)
+
+### 自动分页
+
+`bat`会在一般情况下将大于屏幕可显示范围的内容输出到分页器(pager, e.g. `less`)。
+
+你可以在调用时添加`--paging=never`参数来使`bat`不使用分页器（就像`cat`一样）。如果你想要用为`cat`使用`bat`别名，可以在 shell 配置文件（shell configuration）中添加`alias cat='bat --paging=never'`。
+
+#### 智能输出
+
+`bat`能够在设置了分页器选项的同时进行管道:wink:。
+当`bat`检测到当前环境为非可交互终端或管道时（例如使用`bat`并将内容用管道输出到文件），`bat`会像`cat`一样，一次输出文件内容为纯文本且无视`--paging`参数。
+
+## 如何使用
+
+在终端中查看一个文件
+
+```bash
+> bat README.md
+```
+
+一次性展示多个文件
+
+```bash
+> bat src/*.rs
+```
+
+从`stdin`读入流，自动为内容添加语法高亮（前提是输入内容的语言可以被正确识别，通常根据内容第一行的 shebang 标记，形如`#!bin/sh`）
+
+```bash
+> curl -s https://sh.rustup.rs | bat
+```
+
+显式指定`stdin`输入的语言
+
+```bash
+> yaml2json .travis.yml | json_pp | bat -l json
+```
+
+显示不可打印字符
+
+```bash
+> bat -A /etc/hosts
+```
+
+与`cat`的兼容性
+
+```bash
+bat > note.md  # 创建一个空文件
+
+bat header.md content.md footer.md > document.md
+
+bat -n main.rs  # 只显示行号
+
+bat f - g  # 输出 f，接着是标准输入流，最后 g
+```
+
+### 第三方工具交互
+
+#### `fzf`
+
+你可以使用`bat`作为`fzf`的预览器。这需要在`bat`后添加`--color=always`选项，以及`--line-range` 选项来限制大文件的加载次数。
+
+```bash
+fzf --preview 'bat --color=always --style=numbers --line-range=:500 {}'
+```
+
+更多信息请参阅[`fzf`的说明](https://github.com/junegunn/fzf#preview-window)。
+
+#### `find` 或 `fd`
+
+你可以使用`find`的`-exec`选项来用`bat`预览搜索结果：
+
+```bash
+find … -exec bat {} +
+```
+
+亦或者在用`fd`时添加`-X`/`--exec-batch`选项：
+
+```bash
+fd … -X bat
+```
+
+#### `ripgrep`
+
+`bat`也能用`batgrep`来显示`ripgrep`的搜索结果。
+
+```bash
+batgrep needle src/
+```
+
+#### `tail -f`
+
+当与`tail -f`一起使用，`bat`可以持续监视文件内容并为其添加语法高亮。
+
+```bash
+tail -f /var/log/pacman.log | bat --paging=never -l log
+```
+
+注意：这项功能需要在关闭分页时使用，同时要手动指定输入的内容语法（通过`-l log`）。
+
+#### `git`
+
+`bat`也能直接接受来自`git show`的输出并为其添加语法高亮（当然也需要手动指定语法）：
+
+```bash
+git show v0.6.0:src/main.rs | bat -l rs
+```
+
+#### `git diff`
+
+`bat`也可以和`git diff`一起使用：
+
+```bash
+batdiff() {
+    git diff --name-only --diff-filter=d | xargs bat --diff
+}
+```
+
+该功能也作为一个独立工具提供，你可以在[`bat-extras`](https://github.com/eth-p/bat-extras)中找到`batdiff`。
+
+如果你想了解更多 git 和 diff 的信息，参阅[`delta`](https://github.com/dandavison/delta)。
+
+#### `xclip`
+
+当需要拷贝文件内容时，行号以及 git 标记会影响输出，此时可以使用`-p`/`--plain`参数来把纯文本传递给`xclip`。
+
+```bash
+bat main.cpp | xclip
+```
+
+`bat`会检测输出是否是管道重定向来决定是否使用纯文本输出。
+
+#### `man`
+
+`bat`也能给`man`的输出上色。这需要设置`MANPAGER`环境变量：
+
+```bash
+export MANPAGER="sh -c 'col -bx | bat -l man -p'"
+man 2 select
+```
+
+（如果你使用的是 Debian 或者 Ubuntu，使用`batcat`替换`bat`）
+
+如果你遇到格式化问题，设置`MANROFFOPT="-c"`也许会有帮助。
+
+`batman`能提供类似功能——作为一个独立的命令。
+
+注意：[man page 语法](assets/syntaxes/02_Extra/Manpage.sublime-syntax) 还需要完善。在使用特定的`man`实现时该功能[无法正常工作](https://github.com/sharkdp/bat/issues/1145)。
+
+#### `prettier` / `shfmt` / `rustfmt`
+
+`prettybat`脚本能够格式化代码并用`bat`输出。
+
+## 安装
+
+[![Packaging status](https://repology.org/badge/vertical-allrepos/bat-cat.svg)](https://repology.org/project/bat-cat/versions)
+
+### Ubuntu (使用 `apt`)
+
+*... 以及其他基于 Debian的发行版.*
+

+
+## 自定义
+
+### 语法高亮主题
+
+使用 `bat --list-themes` 一份语法高亮主题的清单，然后用`--theme=TwoDark`来指定主题为`TwoDark`，也可以通过设置`BAT_THEME`环境变量来选定主题。把`export BAT_THEME="TwoDark"`添加到 shell 的启动脚本（shell startup file）来取得永久效果。或者使用`bat`的[配置文件](#c配置文件)
+
+若想要查看所有主题在一个文件上的显示效果可以用一下命令（需要安装`fzf`）：
+
+```bash
+bat --list-themes | fzf --preview="bat --theme={} --color=always /path/to/file"
+```
+
+`bat`在默认情况下能够在黑色主题背景下获得较好的效果，如果你的终端使用亮色背景，可以试试`GitHub`或`OneHalfLight`。想要添加自定义主题可以参考[添加主题](#添加主题)。
+
+### 8-bit 主题
+
+`bat` 自带三个 [8-bit 色彩](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors) 主题：
+
+- `ansi` 适应于大部分终端。它使用 3-bit 色彩：黑红绿黄蓝洋红靛青白。
+- `base16`专为 [base16](https://github.com/chriskempson/base16) 终端设计。它使用 4-bit 色彩（带有亮度的 3-bit 色彩）。根据 [base16 styling guidelines](https://github.com/chriskempson/base16/blob/master/styling.md) 制作。
+- `base16-25`专为 [base16-shell](https://github.com/chriskempson/base16-shell) 设计。它把部分亮色替换为 8-bit 色彩。请不要直接使用该主题，除非你清楚你的256色终端是否使用 base16-shell。
+
+尽管这些主题具有诸多限制，但具有一些 truecolor 主题不具有的三个优点：
+
+- 享有最佳兼容性。并不是所有终端工具都支持高于 3-bit 的色彩。
+- 适应终端主题。
+- 视觉上和其他的终端工具更协调。
+
+### 输出样式
+
+你可以用`--style`参数来控制`bat`输出的样式。使用`--style=numbers,chanegs`可以只开启 Git 修改和行号显示而不添加其他内容。`BAT_STYLE`环境变量具有相同功能。
+
+### 添加新的语言和语法
+
+当现有的`bat`不支持某个语言或语法时你可以自己添加。
+
+`bat`使用`syntect`库来支持语法高亮，该库使用 [Sublime Text `.sublime-syntax` 语法文件](https://www.sublimetext.com/docs/3/syntax.html)和主题。而后者中的大部分可以在 [Package Control](https://packagecontrol.io/) 找到。
+
+当你找到一份语法文件，按照下列方法：
+
+1. 创建包含语法描述文件的目录：
+   
+   ```bash
+   mkdir -p "$(bat --config-dir)/syntaxes"
+   cd "$(bat --config-dir)/syntaxes"
+   
+   # Put new '.sublime-syntax' language definition files
+   # in this folder (or its subdirectories), for example:
+   git clone https://github.com/tellnobody1/sublime-purescript-syntax
+   ```
+
+2. 调用下面指令把文件转换为二进制缓存：
+   
+   ```bash
+   bat cache --build
+   ```
+
+3. 最后用`bat --list-languages`来检查新的语法是否被成功导入。如果想要回滚到最初状态，执行：
+   
+   ```bash
+   bat cache --clear
+   ```
+
+4. 如果你觉得`bat`有必要自带该语法支持，请在阅读[指导](doc/assets.md)后向仓库提交 [Syntax Request](https://github.com/sharkdp/bat/issues/new?labels=syntax-request&template=syntax_request.md)。
+
+### 添加主题
+
+类似添加语法支持，第一步也是创建一个带有语法高亮的目录
+
+```bash
+mkdir -p "$(bat --config-dir)/themes"
+cd "$(bat --config-dir)/themes"
+
+# 下载一个主题
+git clone https://github.com/greggb/sublime-snazzy
+
+# 更新二进制缓存
+bat cache --build
+```
+
+然后用`bat --list-themes`检查添加是否成功。
+
+### 添加或修改文件关联
+
+你可以用`--map-syntax`参数添加或修改文件名模板。它需要一个类似`pattern:syntax`的参数来指定，其中`pattern`是 glob 文件匹配模板，`syntax`则是支持的语法的完整名（使用`bat --list-languages`来查看获取一份清单）。
+
+注意：方便起见，你可能需要把参数添加到配置文件，而不是每次都在命令行中传递该参数。
+
+以下展示了把“INI”关联到具有`.conf`扩展名的文件
+
+```bash
+--map-syntax='*.conf:INI'
+```
+
+把`.ignore`文件与“Git Ignore”关联
+
+```bash
+--map-syntax='.ignore:Git Ignore'
+```
+
+把`/etc/apache2`内的`.conf`文件关联到“Apache Conf”语法（`bat`已默认绑定）
+
+```bash
+--map-syntax='/etc/apache2/**/*.conf:Apache Conf'
+```
+
+### 使用自定义分页器
+
+`bat`默认使用`PAGER`环境变量定义的分页器，如果没有定义则使用`less`。`bat`提供了`BAT_PAGER`环境变量来专为`bat`选择分页器（优先级高于`PAGER`）。
+
+注意：当`PAGER`设置为`more`或`most`时，`bat`会使用`less`来代替以确保能提供色彩支持。
+
+```bash
+export BAT_PAGER="less -RF"
+```
+
+除了使用环境变量来改变`bat`使用的的分页器，也可以在配置文件中提供`--pager`参数。
+
+注意：`bat`会把部分命令行参数直接传递给分页器：`-R`/`--RAW-CONTROL-CHARS`,`-F`/`--quit-if-one-screen`以及`-X`/`--no-init`（该参数仅适用于高于530版本的`less`）。其中`-R` 参数需要在解释 ANSI 标准颜色时起作用。`-F`则指示`less`在输出内容的垂直尺寸小于终端尺寸时立即退出。当文件内容可以在一个屏幕里完全显示时，就不需要按`q`键退出阅读模式，很方便就是了。`-X`则能修复`-F`在`less`的老版本中的一些bug（代价是不支持鼠标滚轮，但可以用`-R`来取消`quit-if-one-screen`功能。）。
+
+### 缩进
+
+`bat` 使用四个空格宽的制表符，而不受分页器影响，同时也可以用`--tabs`参数来自定义。
+
+注意：通过其他方法针对分页器的制表符设置不会生效（例如通过`bat`的`--pager`参数传递或`less`使用的`LESS`环境变量）。因为在输出提交给分页器之前，内容中的制表符就已经被`bat`替换为了特定长度的空格以避免由于边栏导致的缩进问题。你可以用给`bat`传递`--tabs=0`参数来取消该设定并让分页器自己处理制表符。
+
+### 暗色模式
+
+如果你用的 macOS 处于暗色模式，你可以为`bat`启用基于系统主题的主题。如下所示操作会让`bat`在系统处于亮色模式时加载`GitHub`主题和暗色模式时加载`default`主题。
+
+```bash
+alias cat="bat --theme=\$(defaults read -globalDomain AppleInterfaceStyle &> /dev/null && echo default || echo GitHub)"
+```
+
+## 配置文件
+
+```bash
+bat --config-file
+```
+
+你也可以用`BAT_CONFIG_PATH`来为`bat`指定自定义位置的配置文件：
+
+```bash
+export BAT_CONFIG_PATH="/path/to/bat.conf"
+```
+
+使用`--generate-config-file`参数调用`bat`会在指定位置生成一份默认的`bat`配置文件：
+
+```bash
+bat --generate-config-file
+```
+
+### 格式
+
+配置文件其实是一份按行分割的命令行参数列表。你可以用`bat --help`来查看所有可用的参数和适用的值。配置文件中`#`打头的行会被视为注释而不生效。
+
+以下是一份示例：
+
+```bash
+# 设置主题为 TwoDark
+--theme="TwoDark"
+
+# 显示行号和 Git 修改信息， 但没有边框
+--style="numbers,changes,header"
+
+# 在终端中以斜体输出文本（不是所有终端都支持）
+--italic-text=always
+
+# 使用 C++ 语法来给 Arduino 的 .ino 文件提供高亮
+--map-syntax "*.ino:C++"
+```
+
+## 在 Windows 中使用 `bat`
+
+`bat` 在 Windows 上开箱即用，除了部分功能需要额外配置。
+
+### 前置条件
+
+你需要先安装 [Visual C++ Redistributable](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) 包。
+
+### 分页
+
+Windows 只有一个提供有限功能的分页器，你可以从[这里下载](http://www.greenwoodsoftware.com/less/download.html)或用 [Chocolatey 安装](https://chocolatey.org/packages/Less) Windows 版本的`less`。第一种方法需要你把它所在目录加入`PATH`环境变量或[定义分页器变量](#使用自定义分页器)
+
+### 色彩
+
+Windows 10 从 [v1511](https://en.wikipedia.org/wiki/Windows_10_version_history#Version_1511_(November_Update)) 开始 shell（`conhost.exe`，命令提示符或 Powershell）原生支持色彩。在早些版本的 Windows 中你可以用第三方终端如 [Cmder](http://cmder.net/) （使用[ConEmu](https://conemu.github.io/)）。
+
+注意：Git 和 MSYS 版本的 `less` 没法正确在 Windows 表达色彩。如果你没有安装其他分页器，你可以直接用`--paging=never`或设置`BAT_PAGER`为空字符串来关闭分页功能。
+
+### Cygwin
+
+Windows 上的`bat`原生不支持 Cygwin' unix-style 路径（`/cygdrive/*`）。当传递一个绝对 cygwin 路径作为参数值时，`bat`会产生`The system cannot find the path specified. (os error 3)`的错误。你可以`.bash_profile`文件中添加以下函数来解决这个问题。
+
+```bash
+bat() {
+    local index
+    local args=("$@")
+    for index in $(seq 0 ${#args[@]}) ; do
+        case "${args[index]}" in
+        -*) continue;;
+        *)  [ -e "${args[index]}" ] && args[index]="$(cygpath --windows "${args[index]}")";;
+        esac
+    done
+    command bat "${args[@]}"
+}
+```
+
+## 疑难解答
+
+### 输出内容含糊不清
+
+当输入文件包含颜色代码和其他 ANSI 转义符号时，`bat`会产生错误的语法高亮和文本，导致输出看起来令人无法理解。当你需要输出该文件时，请使用`--color=never --wrap=never`参数来关闭上色和文字包裹。
+
+### 终端与色彩
+
+`bat`会区分支持 truecolor 和不支持 truecolor 的终端。但是大部分语法高亮主题都是用了没有为 8-bit 色彩支持的颜色，因此强烈推荐使用一个支持 24-bit 色彩的终端（`terminator`，`konsole`，`iTerm2`...），或使用一个 [8-bit 主题](#8-bit-主题)来限制一些颜色。查看[这篇文章使用自定义分页器](https://gist.github.com/XVilka/8346728)了解更多支持 truecolor 的终端。你需要定义`COLORTERM`变量为`truecolor`或`24bit`来确保`bat`能够识别终端的对颜色的支持，否则会使用 8 bit 模式。
+
+### 行号和边框很难看清
+
+试试其他主题，说不定能有所改善（用`bat --list-themes`查看主题列表）。
+
+### 文件编码
+
+`bat`原生支持 UTF-8 和 UTF-16。至于其他文件你可能需要在使用`bat`之前先把编码转换到UTF-8。
+
+这里展示了使用`iconv`来把 Latin-1(ISO-8859-1) 编码的 PHP 文件转换到 UTF-8：
+
+```bash
+iconv -f ISO-8859-1 -t UTF-8 my-file.php | bat
+```
+
+注意： 当`bat`无法识别语言时你可能会需要`-l`/`--language`参数。
+

+# Release checklist
+
+## 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`. Check with
+      `git grep -i -e 'rust.*1\.' -e '1\..*rust' | grep README | grep -v tests/`.
+- [ ] Update `CHANGELOG.md`. Introduce a section for the new release.
+
+## Update syntaxes and themes (build assets)
+
+- [ ] Install the latest master version (`cargo clean && cargo install --locked -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 `-h`, `--help`, and the `man` page. All of these are shown in
+      the output of the CI job called *Documentation*, so look there.
+      The CI workflow corresponding to the tip of the master branch is a good place to look.
+
+## 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 syntaxes
+      and themes).
+- [ ] Run `cargo publish --dry-run` to make sure that it will
+      succeed later (after creating the GitHub release).
+
+## Release
+
+- [ ] Create a tag and push it: `git tag vX.Y.Z; git push origin tag vX.Y.Z`.
+      This will trigger the deployment via GitHub Actions.
+      REMINDER: If your `origin` is a fork, don't forget to push to e.g. `upstream` instead!
+- [ ] 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.
+
+## Post-release
+
+- [ ] Prepare a new "unreleased" section at the top of `CHANGELOG.md`.
+      Put this at the top:
+
+```

+
+Please note, that being sponsored does not affect the individuality of the `bat`
+project or affect the maintainers' actions in any way.
+We remain impartial and continue to assess pull requests solely on merit - the
+features added, bugs solved, and effect on the overall complexity of the code.
+No issue will have a different priority based on sponsorship status of the
+reporter.
+
+Contributions from anybody are most welcomed, please see our [`CONTRIBUTING.md`](../CONTRIBUTING.md) guide.
