The document discusses molecule editors, which are computer programs used to create and modify representations of chemical structures. It provides examples of popular molecule editors like JME and JSME. JME was originally developed in Java but has been ported to JavaScript as JSME, making it usable in web browsers. JSME aims to provide the same functionality as JME through an intuitive interface for drawing and editing molecular structures.

3.  A molecule editor is a computer program for creating and
modifying representations of chemical structures.
 Molecule editors can manipulate chemical structure
representations in either two- or three-dimensions. editors
generate output used as illustrations or for querying chemical
databases. Three-dimensional molecule editors are used to build
molecular models, usually as part of molecular
modelling software packages.
 Database molecular editors such as Leatherface, and Molecule
Slicer allow large numbers of molecules to be modified
automatically according to rules such as 'deprotonate carboxylic
acids' or 'break exocyclic bonds' that can be specified by the
user.
 Molecule editors typically support reading and writing at least
one file format or line notation. Examples of each
include and SMILES, respectively.

4.  Students can use the molecule editor to learn
how to create molecules. The molecule editor
allows students to draw molecules that follow
the rules for covalent bond formation and
formal charge, even if the molecules are
chemically impossible, are unstable, or do not
exist in living systems. The molecule editor
warns students if they try to submit a
structure that is chemically impossible.

5.  The JME Molecular Editor is a Java applet with which one
can make and edit drawings, both of molecules and of
reactions (including generation of substructure queries),
and can display molecules within an HTML page. The
editor can generate Daylight SMILES or MDL Molfiles of the
created structures.
 The JME Editor was written by Peter Ertl while at Comenius
University and later at Ciba-Geigy, Basel.
 It is available free for non-commercial use and has
become a standard for molecular-structure input on the
web.[
 JME has been ported to JavaScript using the Google Web
Toolkit (GWT). In analogy to JME the JavaScript editor is
named JSME

6.  A molecule editor, i.e. a program facilitating graphical
input and interactive editing of molecules, is an
indispensable part of every cheminformatics or
molecular processing system. Today, when a web
browser has become the universal scientific user
interface, a tool to edit molecules directly within the
web browser is essential. One of the most popular
tools for molecular structure input on the web is the
JME applet. Since its release nearly 15 years ago,
however the web environment has changed and Java
applets are facing increasing implementation hurdles
due to their maintenance and support requirements,
as well as security issues. This prompted us to
update the JME editor and port it to a modern Internet
programming language - JavaScript.

10.  The Drawing mode will allow you to draw a
Carbon on your spectral window just by clicking
on any empty field. Clicking on any existing atom
will add an additional carbon. If you click on a
single bond, you will get a double bond (clicking
on a double bond will draw a triple bond).
 Although designed for University level research,
the following software packages are ideal to
supplement high school and advanced middle
school chemistry lessons. The software can also
be used as a tool for student science projects.

12.  The actual molecule editing Java code of the JME
editor was translated into JavaScript with help of the
Google Web Toolkit compiler and a custom library
that emulates a subset of the GUI features of the Java
runtime environment. In this process, the editor was
enhanced by additional functionalities including a
substituent menu, copy/paste, drag and drop and
undo/redo capabilities and an integrated help. In
addition to desktop computers, the editor supports
molecule editing on touch devices, including iPhone,
iPad and Android phones and tablets. In analogy to
JME the new editor is named JSME. This new molecule
editor is compact, easy to use and easy to
incorporate into web pages.

13.  A free molecule editor written in JavaScript was developed
and is released under the terms of permissive BSD license.
The editor is compatible with JME, has practically the same
user interface as well as the web application programming
interface. The JSME editor is available for download from
the project web page.
 We described development and the capabilities of JSME, a
free molecule editor written in JavaScript. JSME was
developed as direct successor of the popular JME applet,
using the JME codebase, therefore although being a new
program, it benefits from 15 years of user feedback and
bug fixing. JSME is released under the permissive BSD
license, which allows the editor to be used freely in both
nonprofit and commercial environments. Implementation
of JSME in web pages is very simple; therefore we hope
that this new molecule editor will become a useful
component of numerous new, exciting cheminformatics
Internet tools and web services.
