LangTrans is a syntactic preprocessor that lets you customize any programming language's syntax.
It translates your custom syntax into the original language, allowing personalized coding while adhering to language specifications.
Using regular expressions, it extracts tokens from your custom language to generate the original syntax.

There are two ways you can install LangTrans:

Use the following command to clone the repository:

git clone https://github.com/LangTrans/LangTrans.git

After cloning, navigate into the LangTrans directory.

Go to Releases and download the latest executable or a installer.

You can use LangTrans from the command line using the following structure:

py langtrans.py <SoureFileName> <OutputFileName> <SyntaxRepr> <PatternRepr>

• SoureFileName: Name of the source code file written with your new syntax
• OutputFileName: Name of the source code file you want to generate with the original syntax
• SyntaxRepr: Name of the YAML file for your syntax representation (without .yaml extension)
• PatternRepr: Name of the YAML file for the pattern representation of the original language (without .yaml extension)

You can also use the following options with the langtrans.py command:

• -h: Displays help information
• -v: Activates verbose mode
• -y: Executes the 'after' command automatically
• -n: Exits without executing the 'after' command

Here is our take on custom Python:

#Print
p"Hello World"

# Anonymous function
inc = (x) => x+1

# Lambda function
twice(x) = 2*x

# Single Line try-except
try inc("1") Exception print("Error:",err)

# Print Done if x is defined other wise Failed
print((x||True)?"Done":"Failed")

# Single Line if and check x defined or not
print('x is not defined') if !x

# Pipe Syntax
1 -> inc
|> print

# Arithmetic operations with functions
print((inc+twice)(3))

#Scope syntax work like in javascript
#scope1#
print("Scope1")
print("Done")

#scope2#
print("scope2")
print("Done")

#PEP 359 - The "make" statement
make type name(arg):
  x = 1
  y = 3

Here is a sample of the customized Common Lisp:

func printhis(s):
  format(t,s)
printhis("Customized!")
