Module format 

{placeholder} substitution for --format and --tooltip-format.

Same surface as claudebar (claudebar:625-667): placeholders are surrounded by {}, unknown placeholders are left untouched (matching bash parameter expansion’s default behavior — claudebar uses ${text//\{x\}/$val} which is a no-op for unknown keys).

Built on a Map<&str, String> so each vendor can register its own placeholder set and the rendering code doesn’t need to know what they are.

Functions

capitalize

Upper-case the first character, leaving the rest alone.

local_date_hm

local_time_hm

local_time_hms

money

A monetary amount, with the sign outside the symbol. format!("${v:.2}") puts it inside — $-5.71 — which reads as a typo rather than as debt, and several providers let a balance go negative: OpenRouter overruns its credits, Moonshot carries an explicit cash_balance debt.

placeholders

Convenience: build a placeholder map from (&str, impl Into<String>) pairs.

reset_credit_lines

One row per banked reset, soonest expiry first. This is what the panel, TUI, and tooltip list — a single “2 available · next expires Oct 4” line hides that two credits can lapse hours apart on the same day.

reset_credits

Compact count for placeholders and tooltips that have to stay on one line.

substitute

Substitute every {key} in template with values[key]. Unknown keys are left as-is.

updated_at_hm

usd

money for the providers that only ever bill in dollars.

with_currency

Attach a currency to an already-formatted magnitude and sign.
