compilerlab5 0.1.1

# compilerlab5

A pip-installable package containing five Compiler Design laboratory programs based on **Experiment 6-10.pdf**:

1. LALR bottom-up parser demo

2. SLR(1) parsing demo

3. Three-address code generator

4. Lexical analyzer for operators

5. Shift-reduce parser

## Installation

Install the package from PyPI:

python -m pip install compilerlab5

After installation, the package can be used from any supported Python environment.

## Usage

### 1. LALR Bottom-Up Parser

compilerlab5 lalr

Example input:

i+i\*i

### 2. SLR(1) Parser

compilerlab5 slr

Example input:

dd

### 3. Three-Address Code Generator

compilerlab5 tac

Example input:

a+b\*c

### 4. Lexical Analyzer for Operators

compilerlab5 operator

Example input:

\+

### 5. Shift-Reduce Parser

compilerlab5 shift-reduce

Example input:

id+id\*id

## Individual Commands

The individual console commands are also available:

lalr-parser

slr-parser

tac-generator

operator-validator

shift-reduce-parser

## Python Module Usage

The package can also be executed through Python:

python -m cpp lalr

python -m cpp slr

python -m cpp tac

python -m cpp operator

python -m cpp shift-reduce

Here, cpp is the internal Python package name, while compilerlab5 is the public PyPI distribution name.

## Local Testing

From the project directory:

python -m pip install --upgrade build

python -m build

Install the generated wheel:

python -m pip install dist/compilerlab5-0.1.1-py3-none-any.whl

## PyPI Publishing

Build the package:

python -m build

Check the generated distributions:

dir dist

Upload the distributions using Twine:

python -m twine upload dist/\*

For PyPI authentication, use the username:

\_\_token\_\_

and a valid PyPI API token as the password.

## Portability

The Python package does **not** require GCC or Clang to run the Python implementations.

Python is required on the target system.

The original C source files from the supplied **Experiment 6-10.pdf** are also included under:

src/cpp/c\_sources/

These source files are included for laboratory/reference purposes.

## Package Information

**Distribution name:** compilerlab5

**Python package/module:** cpp

**Current version:** 0.1.1

**License:** MIT

## Educational Purpose

This is a teaching/laboratory package containing examples for Compiler Design experiments 6-10.

The parser examples intentionally follow the structure and terminology of the supplied laboratory material and are intended for educational use rather than as a production compiler toolkit.
