+# oai-codex-ansi-escape
+
+Small helper functions that wrap functionality from
+<https://crates.io/crates/ansi-to-tui>:
+
+```rust
+pub fn ansi_escape_line(s: &str) -> Line<'static>
+pub fn ansi_escape<'a>(s: &'a str) -> Text<'a>
+```
+
+Advantages:
+
+- `ansi_to_tui::IntoText` is not in scope for the entire TUI crate
+- we `panic!()` and log if `IntoText` returns an `Err` and log it so that
+  the caller does not have to deal with it
