Simple task manager.

Task Manager

Simple task manager.

Allows to add, update and delete tasks. Every task can have a title, description, due date and status.

Tasks are stored in a JSON file named .tm in user's home directory.

The Task Manager executable file is located in ./target/tm.

As this file is created using GraalVM SDK, it is not necessary a local Java SDK install to execute it. Just execute it or add it to the local PATH variable or, even better, move it to a directory wich is already in the PATH like /usr/local/bin/

Usage

Develop

Create an executable file

Create a native executable file with GraalVM is a time-consuming process.
For fast feedback during development is easier to create an executable file which depends on the local installed JDK.

mvn package appassembler:assemble

This new executable file will be located in ./target/appassembler/bin/tm

Create a native executable file

A native executable file located in ./target/tm is distributed with the code and ready to use.

Recreate this file needs some requirements:

First, Install GraalVM with SDKMAN or directly from GraalVM web:

sudo mkdir /usr/local/java
cd /usr/local/java
sudo wget https://download.oracle.com/graalvm/22/latest/graalvm-jdk-22_linux-x64_bin.tar.gz
sudo tar zxvf graalvm-jdk-22_linux-x64_bin.tar.gz
sudo rm graalvm-jdk-22_linux-x64_bin.tar.gz
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/graalvm-jdk-22.0.2+9.1/bin/java" 1
sudo update-alternatives --config java  # Choose GraalVM
export PATH=/usr/local/java/graalvm-jdk-22.0.2+9.1/bin:$PATH  # Put this line in ~/.bashrc
source ~/.bashrc
java -version
native-image --version

The native-image tool, from GraalVM, depends on the local toolchain. To install it:

• Linux: sudo apt install build-essential zlib1g-dev
• MacOS: xcode-select --install
• Windows: Install Visual Studio 2022 version 17.6.0 or later, and Microsoft Visual C++ (MSVC).

Compile the project and build a native executable file at one step:
mvn -Pnative package

The native executable, named tm, is created in the target/ directory of the project. To run the executable:./target/tm

Bash autocompletion

To enable Bash autocompletion for the new tm executable:

sudo apt install bash-completion
sudo cp tm-bash-completion.sh /etc/bash_completion.d/tm
source /etc/bash_completion
