dsl - 开始使用 Helvetia

Question

我愿意开始将我的语言嵌入到 Helvetia，但我真的不知道从哪里开始。几周前，我使用 Petit Parser 编写了解析部分。我想嵌入类似于以下的代码，例如 Helvetia 页面中的 sql 示例：

main ()
{
Put(Red)
Move(North)
}

我期待一些比 Helvetia 示例更简单的指南：P

There are various examples included with the distribution of Helvetia that do exactly what you are asking for and that you might want to study:

Cutie-Helvetia-Automaton uses the low-level Helvetia infrastructure to integrate an automaton language defined in CUAutomatonGrammar.
Cutie-LanguageBoxes-SQL uses the high-level language boxes infrastructure to embed SQL defined in LBSqlGrammar into Smalltalk.

你可以调查一下

特别是 SCG 链接中关于 Language Boxes (6) 和 Embedding Languages without broken tools (&) 的出版物更详细地解释了如何使用 helvetia
