The home of the SCRUM programming language. Designed for being a language which is understandable for business as well as for developers and losely inspired by the Scrum (software development) framework (hence the name of course).
So you can become an actual Master of SCRUM programming instead of being just a 'Scrum Master' (without even coding)! Or in other words a SCRUM MASTER PROGRAMMER!
Inspired by being a Rockstar developer (the programming language developed by Dylan Beattie) and wanting to really comprehend the creation and work of an actual programming language I decided to develop my own. As by origin being a Java Developer and because everyone has Java on his computer I used Java as base for the new language.
A glance of the scrum programming language using the 'Hello World' example:
#SPRINTGOAL Deliver our first Scrum program
EPIC "SampleStories"
USER STORY "HelloWorld"
#REVIEW Our first Scrum Program
SAY "Hello world!"
END OF STORY
END OF EPIC
Example code files can be found within SCRUM Examples.
The SCRUM Examples can be executed and debugged using the ScrumLanguageTest. The project is build upon JAVA 17 (LTS).
To run SCRUM programs locally, the scrum distributable can be used (make sure to have a recent java version installed). This can either be generated running a maven build (distribution will be generated within the /development directory), or directly downloading the scrum.zip distributable.
To run a program from the repository code, navigate to Development and run following code via CLI:
scrum examples/HelloWorld.scrum
You can use the SCRUM Examples for testing purposes. Keep in mind running this in Powershell you'll need to run it with:
.\scrum examples/HelloWorld.scrum
If you want to run the code from anywhere, you can create a SCRUM_HOME variable and add it to the system varaiables. Set the SCRUM_HOME environment variable pointing to your SCRUM installation and add this variable into your PATH variable adding %SCRUM_HOME%.
Scrum programs are UTF-8 files with the .scrum file extension.
SCRUM code is a structure based upon EPIC's containing multiple USER STORIES or for simple coding purposes on single/multiple USER STORIES. An EPIC can be interpreted as a single class, whereas User stories can be seen as single functions. These User Stories are individual blocks of code logic which can be executed individually. Multiple stories within an epic will fulfil a bigger goal all together.
EPICS an USER STORIES have a name, defined between quotes (without spaces). These epics can be called afterwards (without the spaces).
EPIC "nameOfTheEpic"
USER STORY "nameOfTheUS"
... code logic ...
END OF USER STORY
END OF EPIC
All code blocks (e.g. EPIC, USER STORY but also IF or ITERATIONS) are always closed by an END STATEMENT (combinining the initial parent). So for an "EPIC" block, this will be closed by "END OF EPIC".
Initialising a new EPIC and calling an EPICs User Story:
SampleStoriesEpic IS NEW nameOfTheEpic
SampleStoriesEpic::nameOfTheUS USING []
All operators are written uppercase for easy readability (as user stories are written in a comprehensive way, we must make a distinction).
Assigning a variable: variable name IS expression
helloWorldText IS "Hello World!"
firstNumber IS 1
BACKLOG = { , , ... } example_backlog = { 1, 2, "three"} empty_backlog = {}
| Operator | Value | Precedence | Example |
|---|---|---|---|
| Assignment | IS |
1 | a = 5 |
| Append value to array | ADDING |
1 | array ADDING "value" |
| Logical OR | OR |
2 | true OR false |
| Logical AND | AND |
3 | true AND true |
| Left side | ( |
4 | |
| Right side | ) |

| Equals | = |
5 | a = 5 |
| Not Equals | != |
5 | a != 5 |
| Greater Than Or Equals | >= |
5 | a >= 5 |
| Greater Than | > |
5 | a > 5 |
| Less Than Or Equals | <= |
5 | a <= 5 |
| Less Than | < |
5 | a < 5 |
| Addition | + |
6 | a + 5 |
| Subtraction | - |
6 | a - 5 |
| Multiplication | * |
7 | a * 5 |
| Division | / |
7 | a / 5 |
| Floor Division | // |
7 | a // 5 |
| Modulo | % |
7 | a % 5 |
| NOT | ! |
8 | !false |
| EPIC Instance | NEW |
8 | a IS NEW epicName [ 5 ] |

Scrum keywords are case-sensitive. All keywords are written uppercase for easy readability as user stories are written in a comprehensive way, we must make a distinction.
SAY something
ASK something
Example of condition statement:
IF ..condition..
... DO SOMETHING ...
ELSEIF ..condition..
... DO SOMETHING ...
ELSE ..condition..
... DO SOMETHING ...
END IF
Example of iteration statement:
I WANT TO ITERATE i FOR RANGE 0 TILL listLength
... do something with i ...
END OF ITERATION
The base code started from a sample project of @alexandermakeev toy-language. A very fine starting base to get a good comprehension of developing a new programming language. The original version of the SCRUM programming language was developed and designed by @janvanwassenhove (aka mITy.John - follow mITy.John on Instagram).
