Seonbi: SmartyPants for Korean language

=======================================

[![](https://dahlia.github.io/seonbi/showcase.svg)][demo web app]



(TL;DR: See the [demo web app].)



Seonbi (선비) is an HTML preprocessor that makes typographic adjustments

to an HTML so that the result uses accurate punctuations according to

the modern Korean orthography.

(It's similar to what [SmartyPants] does for text written in English.)



It also transforms `ko-Kore` text (國漢文混用; [Korean mixed script]) into

`ko-Hang` text (한글전용; Hangul-only script).



Seonbi provides a Haskell library, a CLI, and an HTTP API; any of them can

perform the following transformations:



 -  All hanja words (e.g., `漢字`) into corresponding hangul-only words

    (e.g., `한자`)

 -  Straight quotes and apostrophes (`"` & `'`) into curly quotes HTML

    entities (`“`, `”`, `‘`, & `’`)

 -  Three consecutive periods (`...` or `。。。`) into an ellipsis entity (`…`)

 -  Classical (Chinese-style) stops (`。` & `、`) into modern (English-style)

    stops (`.` & `,`)

 -  Pairs of less-than and greater-than inequality symbols (`<` & `>`) into

    pairs of proper angle quotes (`〈` & `〉`)

 -  Pairs of two consecutive inequality symbols (`<<` & `>>`) into

    pairs of proper double angle quotes (`《` & `》`)

 -  A hyphen (`-`) or hangul vowel *eu* (`ㅡ`) surrounded by spaces, or

    two/three consecutive hyphens (`--` or `---`) into a proper em dash (`—`)

 -  A less-than inequality symbol followed by a hyphen or an equality

    symbol (`<-`, `<=`) into arrows to the left (`←`, `⇐`)

 -  A hyphen or an equality symbol followed by a greater-than inequality

    symbol (`->`, `=>`) into arrows to the right (`→`, `⇒`)

 -  A hyphen or an equality symbol wrapped by inequality symbols (`<->`, `<=>`)

    into bi-directional arrows (`↔`, `⇔`)



Each transformations can be partially turned on and off, and some

transformations have many options.



All transformations work with both plain texts and rich text tree.

In a similar way to SmartyPants, it does not modify characters within

several sensitive HTML elements like `
`/``/``/`<kbd>`.

Chinese/Japanese stops or hanzi/kanji characters inside elements with

`lang="zh"`/`lang="ja"`[^1] are never transformed.



[^1]: Technically, only Korean contents and language-unspecified elements

      are transformed.  Elements having `lang` attribute with language tags

      referring to any Korean language are treated as Korean contents,

      e.g., `ko`, `ko-Hang`, `kor-KP`, `kor-Kore`.

End-user apps

-------------



Technically, Seonbi is basically exposed as a software component,

which is also known as API (application programming interface), to be used

as a module of other softwares.



However, as these official interfaces are not for humans but machines, it's

not easy to use for end-users whom haven't experienced software

programming.  For such end-users, here's the list of end-user apps:



 -  [Demo web app]: The official web app.  Not that mobile-friendly

    (usable though).

 -  [Seonbi Translator] (선비 번역기): An iOS shortcut made by

    [Heechan Bak] ([@channprj]).

 -  [seonbi-webapp]: Probably aims to replace the official web app.

    Made by Lee Dogeon ([@moreal]).

 -  [seonbi-ext]: A browser extension made by Lee Dogeon ([@moreal]).

Installation

------------



Seonbi provides official executable binaries for Linux (x86_64), macOS (Apple

silicon & Intel), and Windows (64-bit).  You can download them from

the [releases] page.



If you prefer [Scoop] on Windows use the Seonbi official bucket:



    scoop bucket add seonbi https://github.com/dahlia/seonbi.git

    scoop install seonbi



It is also distributed as a [Docker image][dockerhub]:



    $ echo '訓民正音' | docker run -i dahlia/seonbi:latest seonbi

    훈민정음



If you'd like to use it on GitHub Actions there is [action

`dahlia/seonbi/setup`][dahlia/seonbi/setup]:



    - uses: dahlia/seonbi/setup

    - run: seonbi -o output.html input.html



If you want to use it as a Haskell library install the [seonbi][hackage] package

using Stack or Cabal.



[Scoop]: https://scoop.sh/

[dahlia/seonbi/setup]: https://github.com/dahlia/seonbi/tree/main/setup



CLI

---



The `seonbi` command basically takes the input HTML as standard input, and

then transforms it into the output HTML as standard output:



    seonbi < input.html > output.html



You could pass a filename as an argument instead (and it is `-` by default):



    seonbi input.html > output.html



There is `-o`/`--output` option as well:



    seonbi -o output.html input.html



Although it automatically detects text encoding of the input file,

you could explicitly specify `-e`/`--encoding`:



    seonbi -e euc-kr -o output.html input.html



Although there are several style options, e.g., `-q`/`--quote`, `-c`/`--cite`,

`-r`/`--render-hanja`, in most cases, giving `-p`/`--preset` is enough:



    echo '平壤 冷麵' | seonbi -p ko-kr  # 평양 냉면

    echo '平壤 冷麵' | seonbi -p ko-kp  # 평양 랭면



Read `-h`/`--help` for details:



    seonbi --help



HTTP API

--------



The `seonbi-api` command starts an HTTP server that takes `POST` requests

with an HTML source with transformation options, and responds with

a transformed result HTML.  You can decide a hostname and a port number

with `-H`/`--host` and `-p`/`--port` options:



    seonbi-api -H 0.0.0.0 -p 3800



The following is an example request:



    POST / HTTP/1.1

    Content-Type: application/json

    Host: localhost:3800



    {

      "preset": "ko-kr",

      "contentType": "text/html",

      "sourceHtml": "<p>하늘과 바람과 별과 詩</p>"

    }



The HTTP API server would respond like this:



    HTTP/1.1 200 OK

    Content-Type: application/json

    Server: Seonbi/0.3.0



    {

      "success": true,

      "contentType": "text/html",

      "resultHtml": "<p>하늘과 바람과 별과 시</p>"

    }



If a web app needs to use the HTTP API server, [CORS] should be configured

through `--allow-origin`/`-o` option:



    seonbi-api -o https://example.com



To learn more about parameters interactively, try the [demo web app].



[CORS]: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS



Haskell API

-----------



All functions and types lie inside `Text.Seonbi` module and its submodules.

The highest-level API is `Text.Seonbi.Facade` module.



See also the [API docs] or [Hackage].

Deno API

--------



There is a simple client library for Deno as well.  See also

the [scripts/deno/](scripts/deno/) directory.

Etymology

---------



*[Seonbi]* (선비) means a classical scholar during Joseon periods (14c–19c).

Today there's a meme that calls a person who feels morally superior or has

elitism *seonbi* in the Korean internet.  So *seonbi* and *smarty pants* have

some things in common.
