From c45216ed02d5e630725a4ca32da2cd331f426274 Mon Sep 17 00:00:00 2001 From: Ilya Grigoriev Date: Thu, 14 Sep 2023 16:43:47 -0700 Subject: [PATCH] templates.md docs: Document string literal format We are a little weird about which string escapes we support, and we don't support raw strings. I thought this might be worth documenting.

The following escape +sequences starting with a backslash have their usual meaning: `\"`, `\\`, `\n`, +`\r`, `\t`, `\0`. Other escape sequences are not supported. Any UTF-8 characters +are allowed inside a string literal, with two exceptions: unescaped `"`-s and +uses of `\` that don't form a valid escape sequence. + ### Template type Most types can be implicitly converted to `Template`. No methods are defined.
