Module patterns 

Command classification patterns for identifying compilation commands.

Implements the 5-tier classification system:

• Tier 0: Instant reject (non-Bash, empty)
• Tier 1: Structure analysis (pipes, redirects, background)
• Tier 2: SIMD keyword filter
• Tier 3: Negative pattern check
• Tier 4: Full classification with confidence

Structs

Classification

Result of command classification.

ClassificationDetails

Detailed classification results with per-tier decisions.

ClassificationTier

Detailed result for a single classification tier.

GoBuildOutput

The one project-relative file promised by a supported go build -o.

Enums

CompilationKind

Kind of compilation command detected.

TierDecision

Decision outcome for a classification tier.

Statics

COMPILATION_KEYWORDS

Keywords that indicate a potential compilation command. Used for SIMD-accelerated quick filtering (Tier 2).

NEVER_INTERCEPT

Commands that should NEVER be intercepted, even if they contain compilation keywords. These either modify local state or have dependencies on local execution.

Functions

cargo_xwin_compilation_kind

Recognize explicit cargo-xwin build, check, and clippy entry points, without treating a mention in a Cargo option value as permission to relax the native MSVC gate. Requested Rust targets and toolchains still go through admission. Cache mutation, environment inspection, and other subcommands are deliberately outside this offload surface.

classify_command

Classify a shell command.

classify_command_detailed

Classify a shell command with detailed tier decisions for diagnostics.

compound_local_compilation_segments

Segments of an && chain (all but the last) that look like a compilation command but were not classified as one, and therefore stay local when the chain is rewritten by the hook (issue #50).

declined_compilation_due_to_structure

Detect a command that would be a compilation command if it weren’t for an (unsafe / unhandled) pipe/redirect/background/subshell structure — i.e. one that the classifier declines purely because of its shell structure rather than because the underlying program is not a compiler (issue #24, item 3).

go_build_output

Plan the explicit file output of a supported Go build.

is_cargo_package_verification

Whether Cargo will build and verify a package archive without publishing it.

is_cargo_xwin_build

Backward compatibility helper for cargo-xwin build commands.

normalize_command

Normalize a command by stripping common wrappers (sudo, time, env, etc.)

split_shell_commands

Split a shell command string on unquoted ;, &&, and || operators.
