Casio-LikeCalculatorLib

A simple library that aims to be able to do all the stuff that a scholar calculator can do. Written on JDK8, that's because we want this library to use it on android projects.

I want this library to be able to calculate the same thinks that the casio calculator I used on my secondary school can do. When we reach that point I did not want to stop there, it will be great if we can add new awesome features to it.

How to use it

These instructions will get you a copy of the project to use it on yours.

Downloading the jar

You can get the last jar file here.

Maven Dependency

Some people will prefer to use this lib with a maven project, to do it add this dependency to your pom file:

<dependency>
  <groupId>com.seniorglez.calc</groupId>
  <artifactId>Casio-LikeCalculatorLib</artifactId>
  <version>1.0-snapshot</version>
</dependency>

And then install it from the command line:

mvn install

Android project

You can get the last jar file here.

Using it is very simple you only have to import the jar as in your android project and add the following to the build.gradle file:

    android {
       compileOptions {
           sourceCompatibility JavaVersion.VERSION_1_8
           targetCompatibility JavaVersion.VERSION_1_8
    }
}

And you should be able to import the library classes.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Java

In order to run Maven you will need to install Java's JDK but as long we are using Maven we didn't need to have the specific version of Java that we are using to write owr project (Maven will compile on JDK8 anyway). I recommend to install versions older that JDK8 (minimum JDK7). On my case I'm using JDK11.

I think that everybody who works with Java already knows how to set his JAVA_HOME system variable, but some of you use to set it like this:

    export JAVA_HOME="/usr/lib/jvm/java-11-openjdk/bin"
    
    export PATH=$JAVA_HOME/bin:$PATH

With the most of the programs this will works nice but Maven will not recognize this variable as a valid one. If you have set up your JAVA_HOME like this the only think you need to do is to remove that /bin.

    export JAVA_HOME="/usr/lib/jvm/java-11-openjdk"
    
    export PATH=$JAVA_HOME/bin:$PATH

Maven

We have to install maven to package this project.

If you use Arch Linux or Arch-based distros:

	
	sudo pacman -S maven

If you use ubuntu/devian-based distros:

    sudo apt install maven

If you use MacOS in order to install maven you will have to install Homebrew

    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

And now you can just install it

    
    brew install maven

If you are using Windows download maven form the maven website. And the follow the guide and the advice of the installation guide.

Now we can check if maven works properly

	mvn -version

You should get something like this:

	Apache Maven 3.6.3 (NON-CANONICAL_2019-11-27T20:26:29Z_root)
	Maven home: /opt/maven
	Java version: 11.0.6, vendor: Oracle Corporation, runtime: /usr/lib/jvm/java-11-openjdk
	Default locale: es_ES, platform encoding: UTF-8
	OS name: "linux", version: "5.4.15-arch1-1", arch: "amd64", family: "unix"

Packaging

Package it using Maven

    mvn clean install

Built With

Maven - The software project management tool
JUnit - The unit testing framework

Contributing

Feel free to fork it and made pull request if you think that your own version is better or adds new functionalities. Please after you open the pull request, make sure that you can actually build the library. If you want to add new methods then write also new test for them.

And because we aim to have a safe enviroment for everybody take a look at owr code of conduct.
