cpast-v0.9.2

Release Notes for v0.9.2 (2025-03-01)

clex_gen:

• Changed default range values to i32_min and i32_max for ranges, and u32_min and u32_max for positive ranges.
• Reduced mutations by segregating states, making the generate_testcase method functional, and removing the need for cloning in the case of cpast_cli, resulting in improved efficiency and performance.

cpast_cli:

• Improved support for completions.
• Introduced the --clipboard flag to copy clex output to the clipboard.
• Enhanced the output of cpast ai.

General Improvements

• Enhanced crate documentation for better clarity and usability.

cpast-v0.8.0

0.8.0 (2025-02-23)

Breaking

• String modifier syntax now accepts three arguments, instead of two. New format: S[min,max,charset] (e.g., S[1,10,'cpast is awesome'])

clex_gen

• Now, string modifier accepts escape characters as well like \n, \t, \r, \\, \', \", \0 \a, \b, \f and \v etc!
• Breaking: Modified string modifier syntax to support minimum and maximum length constraints:
  • New format: S[min,max,charset] (e.g., S[10,10,@CH_UPPER@])
  • Old format: S[length,charset] is now deprecated
  • This change enables more precise string length control in pattern generation

clex_llm

• Switched to Gemini2_0Flash model from Gemini1_0

cpast_cli

• Support AI based clex generation using input format and constraints through cpast ai ....

  GEMINI_API_KEY="<gemini-api-key>" cpast ai --input-format="The first line contains an integer T (number of test cases). Each of the next T lines contains two integers N and M." --constraints="1 ≤ T ≤ 10\n1 ≤ N, M ≤ 10^5"

cpast-v0.7.1

Release Notes - Version 0.7.1 (2025-02-22)

Overview

Version 0.7.1 marks a significant step forward as cpast transition to a monorepo structure. Building upon the foundation of cpast_cli, I'm excited to introduce several new tools to enhance the user experience.

Breaking Changes

• Removed the clipboard feature from cpast_cli. (builds might be broken for android[low priority])
• Replaced the CPAST_DEBUG=1 environment variable with the --debug flag in cpast_cli.

Crates

• ccode_runner: https://crates.io/crates/ccode_runner v0.2.0 (new)
• clex_gen: https://crates.io/crates/clex_gen v0.2.1 (new)
• cpast: https://crates.io/crates/cpast v0.7.1 (updated)

Key Updates

Monorepo Migration

• The codebase has been moved to a monorepo, making it easier to manage and allowing for smoother growth in the future.

New Tools

• cpast_api: A Work In Progress (WIP) backend service, currently under development, to facilitate API interactions.
• cscrapper: A tool for gathering competitive programming questions from CodeChef and Codeforces.
• cpastord: A service that connects cpast features with Discord.
• ccode_runner: A flexible engine for running and testing code snippets for various languages. Optimized for repeated runs, robustness, and speed.
• clex_gen: The core of cpast, this tool generates random test cases using the Clex language. Renamed from clex to avoid potential naming conflicts.
• clex_llm: An AI-powered tool leveraging Google Gemini to generate Clex expressions from natural language.

CLI Improvements

• Verbose Output: The cpast_cli now supports a --debug flag for detailed output, replacing the CPAST_DEBUG environment variable (See issue #5).
• Piping in generate: Improved piping capabilities within the cpast generate command.

Performance and Security

• Enhanced Storage Performance: Optimized the file_store component of ccode_runner for improved efficiency.
• Security Audit: Implemented a security audit workflow using cargo deny to scan dependencies for vulnerabilities, ensuring a more secure codebase.

Development and Infrastructure

• Rust 2024 Upgrade: Updated the codebase to Rust 2024, enabling the use of the latest language features and improvements.
• Refined Code Structure: Restructured cpast_cli into ccode_runner and clex_gen for better code organization and maintainability.
• MSRV: Set the Minimum Supported Rust Version (MSRV) to 1.85.0.

General Improvements

• Improved error propagation across the project.
• Enhanced code quality, documentation, and performance.
• Fixed various bugs, including race conditions and panics.
• Updated dependencies to their latest versions.

v0.6.0

Changes since v0.4.0

Clex

Introducing custom character types in String, breaking syntax!

Now, for custom character sets use @CH_ALL@, @CH_UPPER@ etc(as found in Clex Language Specs) or literal string like 'abc' it will generate either of abc!

We also dropped Character Type as it use was not profound! For using Character Type simply replace it with S[1,]

Critical Bug Fix:

[Critical High] Due to race condition, cpast test ... might leave a orphan child process in non --no-stop cases! This will eventually eat all your system memory and potentially crash it as well! This has been fixed as well!

Breaking Changes

• Introduced improved error propagation, (don't exit before error) and improved error types
• Modify public and private function signature to accommodate error propagation

Misc

1. Introduce CPAST_DEBUG env, to reduce verbosity of Success Testcase message! It's now disabled by default! To enable use CPAST_DEBUG=1 cpast test ...

2. Shell completion support! Generate using

   • zsh: cpast --completions=zsh | sudo tee /usr/local/share/zsh/site-functions/_cpast
   • fish: cpast --completions=fish > ~/.local/share/fish/generated_completions/cpast.fish
   • bash: cpast --completions=bash | sudo tee /etc/bash_completion.d/cpast.bash

Full Changelog: rootCircle/cpast@v0.3.3...v0.4.0

v0.3.3 stable

v0.3.x stable release

CLI

• Breaking CLI changes, introduction of two subcommands, test and generate. test for running and comparing two files and finding missing edge cases, while generate is just to generate the testcase and print it to
• generate now supports copying testcases over clipboard using -c flag, using which you can use testcases in other platforms as well
• test subcommand now supports an optional --no-stop flag, that can be used to never stop after only one failing testcase is found

Library Changes

• Strong support for length based checks and charset(string modifiers). Sample usage cpast generate "S[10,'U']"
• 'U' for uppercase, 'L' for lowercase, '0'..'9' for digit, 'N' for Alphanumeric, 'D' for All (including symbols), 'A' for alphabets only!
• Introduction of support for character literal in cpast, currently being used for string modifier expressions only.
• compile_and_test method now requires an boolean argument at last to accord to changes in CLI. This argument as addressed earlier too is to whether or not to stop after one failing testcase is found.
• Minimum Value for Integer in capturing group now automatically conforms to 0, if negative.
• Dependencies update
• Fixed & Updated Docs

Ops

• This release also address compilation issues of users using android, by using --no-default-features flag during compilation.
• Dependencies update of clap to 4.4.18

Performance Fixes

• remake implementation to reduce repeated compilation based on remake implementation in GNU make
• Significant improvement in benchmark performance for test with files of compiled programming language.
