以下是关于 ble.sh 的安装和使用指南：

安装 ble.sh

ble.sh 是一个 Bash Line Editor，提供了类似于 zsh-autosuggestions 的自动补全和语法高亮功能。以下是安装步骤：

1. 克隆 ble.sh 仓库：

   git clone --recursive https://github.com/akinomyoga/ble.sh.git
   

2. 安装 ble.sh：

   make -C ble.sh install PREFIX=~/.local
   

3. 配置 Bashrc：

   echo 'source ~/.local/share/blesh/ble.sh' >> ~/.bashrc
   

4. 重启终端或运行以下命令使配置生效：

   source ~/.bashrc

使用 ble.sh

主要功能

• 自动补全：ble.sh 提供基于命令历史和文件路径的自动补全功能。
• 语法高亮：支持对复杂命令结构的语法高亮，包括嵌套命令和多个 here 文档等。
• 菜单式补全：使用 Tab 键可以在候选列表中选择补全项。

自定义颜色设置

如果你想自定义 ble.sh 的颜色设置，可以使用 ble-face 命令。要使这些设置持久化，请将它们添加到 ~/.blerc 文件中。

1. 创建或编辑 ~/.blerc 文件：

   touch ~/.blerc
   

2. 在 ~/.blerc 中添加颜色设置：

   # 示例：设置命令行输入的背景色和前景色
   ble-face --set background '#000000' --set foreground '#ffffff'
   

3. 保存并退出编辑器。

常见问题

• 安装后无法生效：确保已经正确添加了 source ~/.local/share/blesh/ble.sh 到 .bashrc 文件中，并重启终端或手动运行 source ~/.bashrc。
• 颜色设置不持久：将颜色设置添加到 ~/.blerc 文件中，以使其在每次启动时自动应用。

通过这些步骤，你可以成功安装和使用 ble.sh，享受其带来的自动补全和语法高亮功能！
