CharChem 2.0

System to describe the chemical formulas for WEB.

Official site: [http://charchem.org]

Full documentation on formula descriptions is located in the /docs folder of the repository or here.

Library for use in HTML

Please, see documentation here.

If you want to build the library from the source code yourself, you will need GIT and Node.js. If you have this software on your computer, use the following commands:

git clone https://github.com/Peter-Win/charchem2.ts
cd charchem2.ts
npm i
npm run buildLib

The results will be in the charchem2.ts/lib folder

Connecting a library to a project via NPM

This method allows you to use CharChem both in a browser and in a desktop (server) application. Tested in Node.js.

Installation options:

• npm i charchem2 -S
• or yarn add charchem2

All main features are collected in the file src/ChemSys.ts.

Internationalization

Out of the box, 2 languages ​​are available: English (en) and Russian (ru).

In addition, there is an extended set, presented in the internationalDict.json file. However, this file is useful only for familiarization.

If you need to use an extended language set via the script tag, then it is recommended to use charchem-lang.js. And if the npm library is used, then:

import {ChemSys} from "charchem2";
import {internationalDict} from  "charchem2/dist/internationalDict";
...
ChemSys.addDict(internationalDict);

If the extended set does not contain the language you need, you can fill in the necessary phrases yourself and connect them via ChemSys.addDict.

After the required dictionaries are registered, you can switch to the required language using the following code:

ChemSys.curLang = "en"; // Instead of "en", you can specify any of the registered locales.
