Readme for spade-

[back to package description]


S.P.A.D.E stands of Simple Programming And Debugging Environment.

It contains a simple programming language and a built-in Terminal based IDE.

The following is a small spade program that draws a bunch of random circles in red color, in an SDL window.

graphicswindow(400, 400, true)
setcolor(255, 0, 0)
for i = 1 to 100
  circle(random(10, 300), random(10, 300), random(10, 40))

The entire language and function reference is available in the IDE in an easily searchable way. Press F1 or use the help menu to access it.

NOTE: This is still a very early version. The standard library is virtually non existent, and those function present are the only ones that were required to write the sample programs in the "samples" folder in this repo.

IDE Demo

A short screen recording of SPADE in action can be seen here.



Run from a portable binary.


From source


To install depdendencies:

  apt-get install libsdl2-dev
  apt-get install libsdl2-mixer-dev
  apt-get install libtinfo-dev

You will need the cabal tool. Once you have either of these, running cabal install spade will install it for you.

Or you can download the source package, '.tar.gz' file from hackage, and again use cabal or stack tool to build and install it. After extracting the source to a folder, running either of the following commands in the folder should build and install it.

cabal build && cabal install

stack build && stack install

Building on Raspberry PI

You should be able to install this in a Raspberry Pi 3 or later iterations. The following steps appear to work for a succesful build on a Raspberry Pi 3.

  1. Install GHC version 9.0.1 following steps described
  2. Install stack tool using apt-get install haskell-stack
  3. Increase the swap space to 2GB, disable GUI by booting into terminal mode, and then build the program using stack build --system-ghc.

Depending on your setup, the initial build can take a very long time, like a couple of days.

Getting started

The program should be started by providing a file name. For example,

spade /tmp/temp.spd

If the file does not exist, it will be created on save. If it exist then contents will loaded into the editor.

Other than this are no provisions to select or open a file from within the IDE. The user is supposed to only work with a single file at one time.

To interpret a spade program without starting the IDE, you can use the run command.

spade run /tmp/temp.spd

Will execute the program without opening the IDE.
