Escape sequences
Some scripts may need to print characters reserved by the language, or characters that cannot be typed on a standard keyboard layout. To help with this, Rant offers escape sequences.
Character escapes
Any reserved character can be printed by prefixing it with \:
\{This text will print with braces around it\}
Special escapes
Certain characters are not interpreted verbatim when escaped, and instead have special meaning. Here's a list of them:
| Escape sequence | Output character |
|---|---|
\\ | Backslash |
\n | Line feed (U+000A) |
\r | Carriage return (U+000D) |
\s | Space (U+0020) |
\t | Tab (U+0009) |
\0 | Null character (U+0000) |
\xXX | Byte escape [See below] |
\uXXXX | 16-bit Unicode escape [See below] |
\UXXXXXXXX | 32-bit Unicode escape [See below] |
\U(XXXXXXXX) | Unsized Unicode escape [See below] |
Unicode escapes
Escape sequences can also be used to specify arbitrary Unicode characters by their hexadecimal form:
# Byte escape
\xE4 # 'ä'
# 16-bit Unicode escape
\u2705 # ✅
# 32-bit Unicode escape
\U0001F602 # 😂
# Unsized Unicode escape (1-8 digits)
\U(1f629)\U(1f44c) # 😩👌
