tp.el - Text Properties Library for Emacs
A powerful text properties manipulation library with an innovative layer system
Features • Installation • Quick Start • API Reference • Layer System • 中文文档
tp.el provides a convenient and unified API for manipulating Emacs text properties. Inspired by ov.el for overlays, tp.el offers:
- Unified API: All property-setting functions work on both strings and buffers
- Layer System: Stack multiple property sets on the same text region
- Pattern Matching: Apply properties to text matching strings or regexps
Features
- ✅ Unified Object Support: Functions like
tp-set,tp-match,tp-regexpwork on both strings and buffers - ✅ Clear Semantics:
tp-reset(replace all),tp-set(replace specified),tp-add(deep merge) - ✅ Nested Property Access: Get/set/remove nested sub-properties with path syntax
- ✅ Innovative Layer System: Stack, rotate, and manage multiple layers of properties
- ✅ Layer Groups: Define reusable sets of related layers
- ✅ Search & Navigation: Find and navigate through propertized text
- ✅ Pattern Matching: Apply properties to string/regexp matches with reset/add variants
- ✅ Clean API: Consistent naming and calling conventions
Requirements
- Emacs 28.1+ (uses
object-intervalsfunction) - dash.el (list manipulation utilities)

The Layer System
The layer system is tp.el's innovative feature that allows stacking multiple sets of properties on the same text region. Only the top layer is visible, but lower layers are preserved and can be revealed through rotation or pinning.
Layer Concept
┌─────────────────────────────┐
│ TOP LAYER (visible) │ ← idx=0, What you see
├─────────────────────────────┤
│ Middle Layer (hidden) │ ← idx=1, Preserved
├─────────────────────────────┤
│ Bottom Layer (hidden) │ ← idx=-1, Preserved
└─────────────────────────────┘
Layer Definition
tp-define-layer - Define Layer(s)
Define a single layer or a group of multiple layers.
Single Layer:
(tp-define-layer layer-name
(face (:background "cyan") line-prefix ">>"))
Multiple Layers (Layer Group):
(tp-define-layer my-group
layer-1 ; Reference existing layer
(face (:background "red") line-prefix ">>") ; Anonymous layer
(face (:background "green" :weight bold))) ; Another anonymous layer
The first layer in the definition is the top layer (visible by default).
Examples:
;; Define individual layers
(tp-define-layer highlight
(face (:background "yellow" :foreground "black")))
(tp-define-layer error
(face (:background "red" :foreground "white")
help-echo "Error!"))
(tp-define-layer info
(face (:background "blue" :foreground "white")))
;; Define a layer group
(tp-define-layer status-colors
highlight
error
info)
tp-layer-props / tp-group-props
(tp-layer-props LAYER-NAME)
(tp-group-props GROUP-NAME)
Get properties for a layer or all layers in a group.
tp-layer-undefine / tp-group-undefine
(tp-layer-undefine NAME)
(tp-group-undefine NAME)
Remove layer or group definition.
tp-layer-reset
(tp-layer-reset)
Clear all layer and group definitions.
