# Grapheme Table Generator
|
||
|
|
|
||
|
|
This tool processes Unicode Character Database (UCD) XML files to generate efficient, multi-stage trie lookup tables for properties relevant to terminal applications:
|
||
|
|
* Grapheme cluster breaking rules
|
||
|
|
* Line breaking rules (optional)
|
||
|
|
* Character width properties
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
* Download [ucd.nounihan.grouped.zip](https://www.unicode.org/Public/UCD/latest/ucdxml/ucd.nounihan.grouped.zip)
|
||
|
|
* Run some equivalent of:
|
||
|
|
```sh
|
||
|
|
grapheme-table-gen --lang=rust --extended --no-ambiguous --line-breaks path/to/ucd.nounihan.grouped.xml
|
||
|
|
```
|
||
|
|
* Place the result in `src/unicode/tables.rs`
