**tp.el** 提供了一个便捷统一的 API 来操作 Emacs 文本属性。灵感来自用于叠加层的 [ov.el](https://github.com/emacsorphanage/ov)，tp.el 提供：
|
||
|
||
- **统一 API**：所有属性设置函数同时支持 **字符串** 和 **缓冲区**
|
||
- **图层系统**：在同一文本区域上堆叠多组属性
|
||
- **模式匹配**：将属性应用到匹配字符串或正则表达式的文本
|
||
|
||
## 功能特性
|
||
|
||
- ✅ **统一对象支持**：`tp-set`、`tp-match`、`tp-regexp` 等函数同时支持字符串和缓冲区
|
||
- ✅ **清晰语义**：`tp-reset`（替换全部）、`tp-set`（替换指定）、`tp-add`（深度合并）
|
||
- ✅ **嵌套属性访问**：使用路径语法获取/设置/移除嵌套子属性
|
||
- ✅ **创新图层系统**：堆叠、轮换和管理多层属性
|
||
- ✅ **图层组**：定义可复用的相关图层集合
|
||
- ✅ **搜索和导航**：查找并导航带属性的文本
|
||
- ✅ **模式匹配**：将属性应用到字符串/正则匹配，支持 reset/add 变体
|
||
- ✅ **简洁 API**：一致的命名和调用约定
|
||
|
||
## 系统要求
|
||
|
||
- **Emacs 28.1+**（使用 `object-intervals` 函数）
|
||
- **dash.el**（列表操作工具库）
|
||
|
||
## 安装
|
||
|
||
```elisp
|
||
;; 添加到 load-path
|
||
(add-to-list 'load-path "/path/to/tp")
|
||
(require 'tp)
|
||
```
|
||
|
||
或使用 `use-package`：
|
||
|
||
```elisp
|
||
(use-package tp
|
||
:load-path "/path/to/tp")
|
||
```
|
||
|
||

|
||
|
||
## 快速开始
|
||
|
||
### 设置属性
|
||
|
||
tp.el 提供三个主要的属性设置函数，每个有不同的语义：
|
||
|
||
```elisp
|
||
;; tp-set: 只替换指定的属性，保留其他属性
|
||
(tp-set 1 10 '(face bold help-echo "Hello!"))
|
||
|
||
;; tp-reset: 完全替换所有属性
|
||
(tp-reset 1 10 '(face bold)) ; 其他任何属性都会被移除
|
||
|
||
;; tp-add: 深度合并嵌套属性
|
||
(tp-add 1 10 '(face (:underline t))) ; 与现有 face 合并
|
||
```
|
||
|
||
这三个函数都支持四种调用约定：
|
||
|
||
```elisp
|
||
;; 在当前缓冲区（属性作为列表）
|
||
(tp-set 1 10 '(face bold help-echo "Hello!"))
|
||
|
||
;; 在特定缓冲区
|
||
(tp-set 1 10 '(face bold) some-buffer)
|
||
|
||
;; 在字符串上（0 索引）
|
||
(tp-set 0 5 '(face bold) "Hello World")
|
||
;; => #("Hello World" 0 5 (face bold))
|
||
|
||
;; 在整个字符串上（平铺属性）
|
||
(tp-set "Hello World" 'face 'bold 'help-echo "test")
|
||
;; => #("Hello World" 0 11 (face bold help-echo "test"))
|
||
```
|
||
|
||
### 单属性设置器
|
||
|
||
```elisp
|
||
;; 只设置 face 属性
|
||
(tp-set-face 1 10 'bold)
|
||
(tp-set-face "Hello" 'italic) ; 整个字符串
|
||
|
||
;; 只设置 display 属性
|
||
(tp-set-display 1 10 '(space :width 10))
|
||
```
|
||
|
||
### 获取属性
|
||
|
||
```elisp
|
||
;; 获取特定位置的属性
|
||
(tp-get 5 'face) ; => bold
|
||
|
||
;; 获取嵌套子属性
|
||
(tp-get 5 'face :foreground) ; => "red"
|
||
(tp-get 5 'face :box :color) ; => "blue"（深度嵌套）
|
||
|
||
;; 获取范围内的特定属性
|
||
(tp-get 1 10 'face) ; => bold
|
||
|
||
;; 获取范围内的所有属性
|
||
(tp-get 1 10) ; => (face bold help-echo "Hello!")
|
||
|
||
;; 获取该位置的所有属性
|
||
(tp-at 5) ; => (face bold help-echo "Hello!")
|
||
```
|
||
|
||
### 移除属性
|
||
|
||
```elisp
|
||
;; 移除整个属性
|
||
(tp-remove 1 10 'face)
|
||
|
||
;; 移除子属性
|
||
(tp-remove 1 10 '(face :underline))
|
||
|
||
;; 移除嵌套子属性（保留其他）
|
||
(tp-remove 1 10 '(face :underline (:style :position)))
|
||
;; 从 :underline 中移除 :style 和 :position，如果存在 :color 则保留
|
||
```
|
||
|
||
### 模式匹配
|
||
|
||
```elisp
|
||
;; 将属性应用到缓冲区中所有 "TODO" 出现的位置
|
||
(tp-match "TODO" '(face warning))
|
||
|
||
;; 应用到字符串
|
||
(tp-match "world" "Hello world world" '(face bold))
|
||
;; => #("Hello world world" 6 11 (face bold) 12 17 (face bold))
|
||
|
||
;; 使用 (PATTERN STRING) 格式匹配
|
||
(tp-match '("world" "Hello world") '(face bold))
|
||
;; => #("Hello world" 6 11 (face bold))
|
||
|
||
;; 使用正则表达式
|
||
(tp-regexp "\\b[0-9]+\\b" '(face font-lock-number-face))
|
||
|
||
;; reset 变体（替换匹配处的所有属性）
|
||
(tp-match-reset "TODO" '(face warning))
|
||
(tp-regexp-reset "[0-9]+" '(face bold))
|
||
|
||
;; add 变体（深度合并匹配处的属性）
|
||
(tp-match-add "TODO" '(face (:underline t)))
|
||
(tp-regexp-add "[0-9]+" '(face (:weight bold)))
|
||
```
|
||
|

### 核心属性函数
|
||
|
||
#### `tp-set` - 设置文本属性
|
||
|
||
在字符串或缓冲区区域上设置文本属性。只替换指定的属性，保留其他属性。
|
||
|
||
```elisp
|
||
;; 当前缓冲区（属性作为列表）
|
||
(tp-set START END '(PROPERTY VALUE ...))
|
||
|
||
;; 特定缓冲区或字符串
|
||
(tp-set START END '(PROPERTY VALUE ...) OBJECT)
|
||
|
||
;; 整个字符串（平铺属性）
|
||
(tp-set STRING PROPERTY VALUE ...)
|
||
```
|
||
|
||
**示例：**
|
||
|
||
```elisp
|
||
;; 在缓冲区区域设置 face
|
||
(tp-set 1 10 '(face bold)) ; => (1 . 10)
|
||
|
||
;; 设置多个属性
|
||
(tp-set 1 10 '(face bold help-echo "Click me"))
|
||
|
||
;; 在特定缓冲区设置
|
||
(tp-set 1 10 '(face italic) my-buffer)
|
||
|
||
;; 在字符串上设置属性（0 索引）
|
||
(setq my-string (tp-set 0 5 '(face italic) "Hello World"))
|
||
;; => #("Hello World" 0 5 (face italic))
|
||
|
||
;; 在整个字符串上设置属性
|
||
(tp-set "Hello" 'face 'bold 'mouse-face 'highlight)
|
||
;; => #("Hello" 0 5 (face bold mouse-face highlight))
|
||
```
|
||
|
||
---
|
||
|
||
#### `tp-reset` - 替换所有属性
|
||
|
||
用指定的属性完全替换所有文本属性。
|
||
|
||
```elisp
|
||
(tp-reset START END '(PROPERTY VALUE ...) &optional OBJECT)
|
||
(tp-reset STRING PROPERTY VALUE ...)
|
||
```
|
||
|
||
**示例：**
|
||
|
||
```elisp
|
||
;; 替换区域中的所有属性
|
||
(tp-reset 1 10 '(face bold)) ; 任何现有属性都会被移除
|
||
|
||
;; 在字符串上
|
||
(tp-reset "Hello" 'face 'italic)
|
||
```
|
||
|
||
---
|
||
|
||
#### `tp-add` - 添加/合并属性
|
||
|
||
添加或更新属性，支持嵌套属性列表的深度合并。
|
||
|
||
```elisp
|
||
(tp-add START END '(PROPERTY VALUE ...) &optional OBJECT)
|
||
(tp-add STRING PROPERTY VALUE ...)
|
||
```
|
||
|
||
**示例：**
|
||
|
||
```elisp
|
||
;; 添加属性（保留现有，合并嵌套）
|
||
(tp-add 1 10 '(help-echo "tooltip"))
|
||
|
||
;; 深度合并 face 属性
|
||
(tp-set 1 10 '(face (:foreground "red")))
|
||
(tp-add 1 10 '(face (:background "blue")))
|
||
;; 结果: face 是 (:foreground "red" :background "blue")
|
||
|
||
;; Face 前置 - 符号 face 会被添加到 face 列表的开头
|
||
(tp-set "Hello" 'face 'bold)
|
||
(tp-add "Hello" 'face 'shadow)
|
||
;; 结果: face 是 (shadow bold)
|
||
```
|
||
|

|
||
|
||
#### `tp-set-face` - 设置 Face 属性
|
||
|
||

||
(tp-get POSITION PROPERTY)
|
||
(tp-get POSITION PROPERTY OBJECT)
|
||
|
||
;; 嵌套子属性访问
|
||
(tp-get POSITION PROPERTY SUB-KEY ...)
|
||
|
||
;; 范围 - 特定属性（返回区间列表）
|
||
(tp-get START END PROPERTY)
|
||
(tp-get START END PROPERTY OBJECT)
|
||
|
||
;; 范围 - 属性路径作为列表
|
||
(tp-get START END '(PROPERTY) OBJECT)
|
||
(tp-get START END '(PROPERTY SUB-KEY ...) OBJECT)
|
||
|
||
;; 范围 - 深层嵌套属性路径
|
||
(tp-get START END '(PROPERTY SUB-KEY SUB-SUB-KEY ...) OBJECT)
|
||
|
||
;; 范围 - 从嵌套属性中提取多个键
|
||
(tp-get START END '(PROPERTY SUB-KEY (KEY1 KEY2 ...)) OBJECT)
|
||
|
||
;; 范围 - 所有属性（返回区间列表）
|
||
(tp-get START END)
|
||
(tp-get START END OBJECT)
|
||
|
||
;; 整个字符串（返回区间列表）
|
||
(tp-get STRING)
|
||
(tp-get STRING PROPERTY)
|
||
(tp-get STRING PROPERTY SUB-KEY ...)
|
||
(tp-get STRING PROPERTY SUB-KEY '(KEY1 KEY2 ...))
|
||
(tp-get STRING '(PROPERTY SUB-KEY ...))
|
||
```
|
||
|
||
**示例：**

|
||
|
||
;; 从字符串获取（0 索引）
|
||
(tp-get 0 'face my-string) ; => italic
|
||
|
||
;; 从范围获取 - 返回 (START END VALUE) 区间列表
|
||
(tp-get 1 10 'face) ; => ((1 6 bold))
|
||
|
||
;; 获取多个区间
|
||
(tp-set 0 5 '(face bold) str)
|
||
(tp-set 12 17 '(face italic) str)
|
||
(tp-get 0 17 'face str) ; => ((0 5 bold) (12 17 italic))
|
||
|
||
;; 使用列表形式的属性路径
|
||
(tp-get 5 20 '(face :underline :style) my-string) ; => ((5 20 wave))
|
||
|
||
;; 从整个字符串获取深层嵌套属性
|
||
(tp-get str 'face :underline :color) ; => ((0 5 "green") (6 11 "yellow"))
|
||
|
||
;; 从嵌套属性中获取多个键
|
||
(tp-get str 'face :underline '(:color :style))

**图层系统**是 tp.el 的创新功能，允许在同一文本区域上堆叠多组属性。只有**顶层**可见，但下层会被保留，可以通过轮换或置顶来显示。
|
||
|
||
### 图层概念
|
||
|
||
```
|
||
┌─────────────────────────────┐
|
||
│ 顶层（可见） │ ← 你看到的
|
||
├─────────────────────────────┤
|
||
│ 中间层（隐藏） │ ← 被保留
|
||
├─────────────────────────────┤
|
||
│ 底层（隐藏） │ ← 被保留
|
||
└─────────────────────────────┘
|
||
```
