:question: Requirements


  1. Only Java is required to run the FAST. (JDK 8 or 11 is recommended).

:thinking: How to install?


:desktop_computer: Windows Only

iwr https://raw.githubusercontent.com/jewelshkjony/fast-cli/main/scripts/install/win.ps1 -useb | iex
  1. The installation is successful. Youโ€™re now good to use the FAST CLI.

:computer: Linux, MacOS & Android Termux


  1. Run the the below command on terminal.
curl https://raw.githubusercontent.com/jewelshkjony/fast-cli/main/scripts/install/install.sh -fsSL | sh
  1. The installation is successful. Youโ€™re now good to use the FAST CLI.

:thinking: How to update the FAST


:desktop_computer: Windows Only


  1. Make sure that FAST is already installed on your system.
  2. Run the the below command on Windows PowerShell.
iwr https://raw.githubusercontent.com/jewelshkjony/fast-cli/main/scripts/update/win.ps1 -useb | iex
  1. Done. Check the version of updated FAST.

:computer: Linux, MacOS & Android Termux


  1. Make sure that FAST is already installed on your system.
  2. Run the the below command on terminal.
curl https://raw.githubusercontent.com/jewelshkjony/fast-cli/main/scripts/update/install.sh -fsSL | sh
  1. Done. Check the version of updated FAST.

:thinking: How to create a new FAST project


  1. Open terminal at where you want to create a new FAST project.
  2. Run fast create <ProjectName>
  3. Enter the package name.
  4. Enter author name.
  5. Done.

:thinking: How to declare the component class


  1. You need to annotate with @DesignerComponent to declare extension component classes.
    Example:
@DesignerComponent(
  version = 1,
  versionName = "1.0",
  description = "Developed by JEWEL by Fast.",
  iconName = "icon.png"
)
  • Required attributes: version, iconName
  • Optional attributes: versionName, description, designerHelpDescription, helpUrl, licenseName
  • Ignored attributes: category, androidMinSdk

:thinking: How to build a FAST project


  1. Open termanl at where the FAST project is.
  2. Run fast build to build the project.
  3. Done. The compiled extension should be inside the out directory.

:thinking: How to compile with ProGuard?


  1. Make sure that the proguard attribute is enabled on the fast.yml config file. Ex. proguard: true
  2. Run the build command with -r as an additional argument. Ex. fast build -r

I have dedicated a significant amount of time and effort into developing the FAST. If you find my work beneficial and would like to show your appreciation, you may consider making a donation here.


Thanks a lot to all the beta testers of FAST. Without their feedback and help, it would have been impossible to make FAST a stable compiler. :tada:

Thank you! Since Rush hasnโ€™t been updated since 2021 and the Niotron IDE is also outdated, FAST is very welcome and overdue to make things easier for less experienced developers (like me).

Thank you for your feedback. It is very valuable to me. However, the FAST is able to compile the Niotron IDE extension source code.

Great :smiley:, this is very advanced and Iโ€™m glad that I was one of the beta testers of this wonderful tool.

Iโ€™m using Fast and I want to know if it has support for aar?

Currently, you canโ€™t directly use an aar file to develop extensions. You need to extract the classes.jar from the .aar file. Use any zip viewer application (e.x: Winrar) to unzip it.
