💾 SQL - Modern Data Querying

sql;
  select age, income, spend,
         case when income > 60000 then 'High' else 'Low' end as income_group
  from work.customers
  where age between 25 and 50
  order by income desc;
quit;

DuckDB-powered SQL processing with full dataset integration!

Quick Start

1. Interactive Python Usage

from statlang import StatLangInterpreter

# Create interpreter
interpreter = StatLangInterpreter()

# Create sample data using StatLang syntax
interpreter.run_code('''
data work.employees;
    input employee_id name $ department $ salary;
    datalines;
1 Alice Engineering 75000
2 Bob Marketing 55000
3 Carol Engineering 80000
4 David Sales 45000
;
run;
''')

# Run statistical analysis
interpreter.run_code('''
proc means data=work.employees;
    class department;
    var salary;
run;
''')

2. Jupyter Notebook Usage

1. Install the StatLang kernel:

   python -m statlang.kernel install
   

2. Create a new Jupyter notebook (.ipynb)
3. Select "statlang" as the kernel
4. Write StatLang code in cells and execute

3. VS Code Usage

1. Install the StatLang extension from the marketplace
2. Create a new file with .statlang extension
3. Write your StatLang code
4. Use Ctrl+Shift+P → "StatLang: Run File" to execute

4. Command Line Usage

# Run StatLang code from file
python -m statlang.cli run example.statlang

# Interactive mode
python -m statlang.cli interactive
