Module compressor 

Generic text compressors.

The compressors live in the lean-ctx-compress crate and are re-exported here unchanged. This facade adds what needs the engine: compression steered by the active task intent.

Functions

aggressive_compress

Strips comments, blank lines, and normalizes indentation for maximum token savings.

ansi_density

Returns the ratio of ANSI escape characters to total string length.

diff_content

Produces a compact unified diff between old and new content with line numbers.

is_yaml_ext

True for a YAML file extension (.yaml / .yml).

lightweight_cleanup

Lightweight post-processing cleanup: collapses consecutive closing braces, removes whitespace-only lines, and limits consecutive blank lines to 1.

safeguard_ratio

Safeguard: prevents compression from inflating output or destroying small outputs. For small outputs (<2000 tokens), rejects extreme compression (>95% reduction) that likely lost important content. For large outputs, trusts the pattern.

strip_ansi

Removes ANSI escape codes from a string, returning clean text.

tabular_delimiter

Delimiter for a delimited-table extension, or None for non-tabular files.

task_aware_compress

Compresses content using the active task intent to preserve task-relevant sections.

verbatim_compact

Deduplicates repeated lines, strips boilerplate, and normalizes timestamps/hashes.
