Sprint

Sprint is an interpreted, high-level, dynamically typed programming language. It offers a simplistic syntax and the blazing fast compilation speed of Dart at the same time. As it is only v1, there are only a handful amount of things you can do using Sprint but I genuinely wish to upgrade Sprint in each version and make Sprint a complete programming language!

Get Started!

To get started with Sprint, follow the steps below -

1. Head to https://sprint-olive.vercel.app and download the latest Sprint release.



2. After downloading, copy the path to sprint.exe and add the path into your environmental variables. In my case, sprint.exe is located in my Downloads folders.



3. Fire up your terminal and type "sprint version". You will get the version of Sprint.

Syntax

The syntax is quite simple. If you want to use ; at the end of each line, that's absolutely fine! Sprint won't cause any issue if do or don't put ; at the end of each line. Extra spaces at the start and the end of each line are trimmed and empty lines are simply ignored. You can use comments in your code by adding # or // at the start of a line. Now, let's talk about Exceptions in Sprint. Sprint tries to keep Expections as much clear as possible so that debugging can be easier. Also, I added a feature in the VariableNotFound error called "Variable Suggestor". Suppose you defined a variable weather = "Cloudy"; and then you wanted to print it by writing print weathar; but Sprint will throw a VariableNotFound error. After throwing the error, Sprint will also say Did you mean weather?

Finally, here are all the available things you can perform using Sprint -

Print

print "Hello world!"

Newline charecter \n is also supported.

print "Hello\nworld!"
# Output: Hello
# world!

Tab charecter \t is now supported.

print "Hello\tworld!"
# Output: Hello    world!

String Interpolation

Use { } to insert data into strings.

target = "John Connor"
print "{target}, come with me if you want to live."

# Output : "John Connor, come with me if you want to live."

Define Variables

name = "Peter"
print name

Updating Variables

a = "foo"
b = "bar"
a = b
print a

# Output will be "bar"

Mathmatical Operations

For performing math, Sprint uses function_tree 0.8.13 package. Feel free to take a look at it here: https://pub.dev/packages/function_tree

math = 2 + 2
print math
# Output: 4.0

math = (3 + 2)^3
print math
# Output: 125.0

math = 3 * sin(5 * pi / 6)
print math
# Output: 1.5000000000000009

Comments

You can use # or // for commenting. It's totally upto you.

# This is a comment
name = "Peter"
print name

// This a also a comment
name = "Peter"
print name

Warning: Comments at the end of a line containing code is not supported yet.

name = "Peter"  # This is a comment
print name

This will cause an error. I hope to resolve this issue in future updates.

Multi-line Comments

"""
This is a comment
This is also a comment
Yet another annoying comment
"""
name = "Peter"
print name

Importing

You can import variables from another file using the import and from keywords.
Suppose there are 2 files (main.sp and info.sp) present in your current working directory.

info.sp file contains 2 variables which are name and age. You want to import these variables into main.sp. Here is how you can do it -

Using import

import info 
# This will import all the variables present in info.sp
print "Hello {name}!\nYou are {age} years old."

# Output : Hello Peter!
# You are 17 years old.

Using from

from info import name, age
# This will import only the specified variables from info.sp
print "Hello {name}!\nYou are {age} years old."

# Output : Hello Peter!
# You are 17 years old.

Loop

At this moment, only "for loop" has been implemented but I wish to bring "while loop" as soon as I can.

for i in "Hello!":
    print i
end

# Output :
# H
# e
# l
# l
# o
# !

Exiting Execution

Use exit or Exit to terminate program execution.

name = "Peter"
exit
print name
# "Peter" will not be printed
