Modules

app

TUI-mode state for rgx filter.

json_path

Minimal dotted/indexed path language for JSONL field extraction.

run

TUI event loop for rgx filter.

ui

Rendering for rgx filter TUI mode.

Structs

FilterOptions

Constants

EXIT_ERROR

EXIT_MATCH

Exit codes, matching grep conventions.

EXIT_NO_MATCH

Functions

emit_count

Emit only the count of matched lines.

emit_matches

Emit matching lines to writer. If line_number is true, each line is prefixed with its 1-indexed line number and a colon.

entry

CLI entry point for rgx filter. Reads input, decides between non-interactive and TUI modes, and returns an exit code.

extract_strings

Returns per-line extracted strings. None means the line should be excluded from matching (JSON parse failure, path miss, or non-string value). The returned vector has the same length as lines, so callers can index it directly alongside the raw lines.

filter_lines

Apply the pattern to each line. Returns the 0-indexed line numbers of every line whose match status (matches vs. invert) satisfies options.invert.

filter_lines_with_extracted

Apply the pattern to the extracted string for each line. Lines whose extracted[i] is None are excluded from the match set regardless of whether the pattern is empty or invert is set — a missing/non-string field is not a “line” for matching purposes.

read_input

Read all lines from either a file path or the provided reader (typically stdin). Trailing \n/\r\n is stripped per line. A trailing empty line (from a terminating newline) is dropped.
