4.1.1

What's Changed

Features

• New compiler support: MSVC, clang-cl, Intel C/C++ (icx, icpx), NVIDIA HPC SDK (nvc, nvc++, nvfortran), ARM Compiler 6, and IBM Open XL
• Windows improvements: case-insensitive executable matching and slash-prefix flag support (e.g. /Fo, /Ot)
• Environment variable forwarding: data-driven per-compiler environment variable extraction, replacing hardcoded GCC-only handling
• Install script: add DESTDIR support for packaging workflows

Bug Fixes

• fix: canonical path generation on Windows stripping \\?\ prefix (#683)
• fix: inconsistent flag inheritance - make all resolution transitive
• fix: replace remaining panics with proper anyhow error handling

Performance

• Eliminate temporary String allocations in flag pattern matching
• Remove intermediate Vec<String> from FlagMatch
• Pre-allocate Vec capacity in parse_arguments and parse_environment
• Replace Box<dyn Arguments> with Argument enum (static dispatch)

Code Generation Overhaul

• Extract bear-codegen crate from build.rs flag generation
• Add flag dedup and conflict detection during inheritance
• Add colon separator patterns and pass-through flag support
• Add flag terminator support
• Introduce ResolvedTable with snapshot, schema validation, and property-based tests

Internal Refactoring

• Decouple intercept layer from semantic compiler recognition
• Extract EntryFilter trait and FilteredOutputWriter into filtering module
• Tighten module visibility (pub to pub(super) and private)
• Simplify CompilerCommand to Command, remove OutputCommand wrapper

Documentation

• Updated man page with correct schema version, complete compiler list, and cc/c++ defaults
• Cleaned up README

Closed Issues

• #683 - bear generates invalid canonical paths
• #682 - install.sh should also have a DESTDIR variable

Full Changelog: 4.1.0...4.1.1

4.1.0

What's Changed

Features

• Shell completions: generate completions for bash, zsh, fish, and elvish
• Compiler executable paths: preserve full compiler executable path in compilation database; resolve bare executable filenames to absolute paths
• Install script: new scripts/install.sh with build-time INTERCEPT_LIBDIR validation, replacing manual setup
• DevContainer: introduce devcontainer for streamlined development environment

Bug Fixes

• fix: inline va_arg extraction in variadic exec shims for i686 compatibility
• fix: preserve co-resident LD_PRELOAD libraries during env doctoring
• fix: restore session env vars in system()/popen() for older glibc
• fix: unify preload restoration for system()/popen() with exec-family doctoring
• fix: recover from poisoned mutex in popen/pclose instead of panicking
• fix: replace panic with TryFrom error for empty Execution arguments
• fix: return fmt::Error instead of panicking in Configuration Display impl
• fix: handle Prefix flags with = in name in build-time codegen

Robustness & Stability

• Replace multiple panic!/unwrap paths with proper error handling (thiserror, TryFrom, fmt::Error)
• Reimplement system()/popen() on top of posix_spawnp for safer process creation
• Add hardened interception tests for environment sabotage scenarios
• Replace serde_yml with serde-saphyr for YAML parsing

Compiler Recognition Overhaul

• Move compiler flag definitions from Rust source to YAML with build-time code generation
• Replace per-compiler interpreter structs with a generic FlagBasedInterpreter
• Auto-generate recognition patterns and ignored-executable lists from YAML schema
• Match ignored executables by filename instead of full path

Documentation

• Expanded README with usage guidance, platform info, and limitations
• Improved INSTALL with prerequisites, package manager instructions, and verification steps
• Improved CONTRIBUTING with developer workflow and guidelines

Internal Refactoring

• Split config.rs, infrastructure.rs into module directories
• Split output module (formats.rs, writers.rs) into focused submodules
• Centralize envp traversal into envp_iter iterator; consolidate session context
• Replace empty-string sentinels with Option<String>
• Extensive new test coverage across output, compiler interpreter, and interception modules
