FLO – Simplified Fluent Output

Status: Current

Purpose

Reimplements CLAN’s flo command, which generates a %flo: dependent tier containing a simplified, “fluent” version of each utterance’s main line.

See the CLAN manual for the original command documentation.

Usage

chatter clan flo file.cha

Options

This command has no configurable options.

Behavior

Processing steps:

1. Strips all header lines (no @UTF8, @Begin, @End, etc.)
2. Adds a %flo: dependent tier to each utterance containing the simplified main line: just countable words plus the terminator
3. Strips retrace targets (words/groups before [/], [//], [///], [/-] — the four RetraceKind variants per crates/core/talkbank-model/src/model/content/retrace.rs)
4. Strips non-countable words (xxx/yyy/www, 0word, &~frag, &-um)
5. Strips events (&=thing) and pauses
6. For replaced words ([: form]), uses the replacement (corrected form)
7. Keeps existing dependent tiers (%mor, %gra, etc.)

The %flo: tier is inserted at position 0 (before other dependent tiers).

Differences from CLAN

• Operates on AST rather than raw text.
• Uses the framework transform pipeline (parse -> transform -> serialize -> write).
