Example usage

 import React from 'react';
 import LineInput from 'semantic-ui-react-lineinput';

 class LineInputExample extends React.Component {

     constructor(props) {
         super(props);
         this.state = {
             value: ""
         };
     }

     changeValue = (newValue) => {
         this.setState({ value: newValue });
     }

     render() => {(
         <LineInput value={this.state.value} onValueChange={this.changeValue} />
     )};
 }

LineInput with predefined validations

<LineInput errorText="value must be an integer" validation="integer" value={this.state.value} onValueChange={this.changeValue} />             
<LineInput errorText="Invalid e-mail address" validation="emailAddress" value={this.state.value} onValueChange={this.changeValue} />

LineInput with regular expression validation

const regExp = /^d{3,4}$/;
<LineInput validation={regExp} value={this.state.value} onValueChange={this.changeValue} />

LineInput with validation function

const isEvenNumber = (valueStr) => {
  const value = parseInt(valueStr, 10);
  return value % 2 === 0;
}

<LineInput validation={isEvenNumber} value={this.state.value} onValueChange={this.changeValue} />

LineInput with list of allowed values validation (case sensitive)

const allowedValues = ['value1', 'value2', 'value3'];
<LineInput validation={allowedValues} value={this.state.value} onValueChange={this.changeValue} />

More examples can be found in demo/demo.tsx file.
