Module ada 

Rendering the Ada CST. Spec §5.

One style: three spaces per level, -- comments, one declaration per line, the reserved words in lower case and the identifiers in Mixed_Case_With_Underscores. Three spaces because that is what the Ada Reference Manual’s own examples use and what GNAT’s -gnaty style checks expect; nothing in the language depends on it.

Nothing is decided here. A record either has components or is written null record, and which of the two it is was decided by zerodds_lang_cst::ada::Record::is_null — the renderer only asks.

Two differences from every other renderer in this crate, and both are Ada’s:

1. A string literal doubles its quote. Ada 2012 RM 2.6 spells an embedded quotation mark "", where the C family writes \", so crate::writer::escape_string is not used here at all — it would produce a backslash Ada reads as a graphic character of its own.
2. A comment marker is -- and has no block form. RM 2.7: a comment runs to the end of the line and there is no closing delimiter, so a comment can never swallow the declaration after it.
