uppercase operator.

[eignnx]

create an OutToken which will capitalize the next character it sees.

Proposed Syntax

rule start = !my_sentence + "."

rule my_sentence = "once upon a time I died"

this example would generate the sentence:

Once upon a time I died.

Alternate Syntax

ranked in order of my personal preference

rule start = !my_sentence + "."
rule start = ^my_sentence + "."
rule start = `my_sentence + "."
rule start = :my_sentence + "."
rule start = /my_sentence + "."
rule start = [my_sentence] + "."
rule start = \my_sentence + "."
rule start = &my_sentence + "."

Implementation

1. teach parser how to parse a ! character to some new Token variant

   #[derive(Debug, Clone, PartialEq)]
   pub enum Token {
   RuleRef(RuleRef),
   StrLit(IStr),
   DataVariable(DataVariable),
   DataVariant(DataVariant),
   Plus,
   Bang, // <---
   }

2. add an enum variant to libaffix::gen::OutToken:

   #[derive(Clone, Hash, PartialEq, Eq, Debug)]
   enum OutToken {
   Sym(IStr),
   Plus, // For concatenation without space insertion.
   Upper, // For capitalizing the next character.
   }

3. teach libaffix::gen::join_symbols how to capitalize the next character when it sees an OutToken::Upper variant.
