Introduction[Bearbeiten]
The following describes the data format and syntax used in pin freeze values. In general, the text entered as freeze value is parsed by the input pin's datatype.
Integer[Bearbeiten]
Integer constants can be entered in one of the following formats:
- decimal (for example: "
1234
" , "-1234
) - with Smalltalk radix prefix: (for example: "
16rCAFE
" , "16r-AA
, "8r100
, "2r101010000
) any radix between 2 and 36 is allowed. - with C radix prefix: (for example: "
0xCAFE
" , "-0xAA
, "0b101010000
) (0x for hex, 0o for octal, ob for binary). Notice that the C-octal notation (prefix 0) is not supported.
Float[Bearbeiten]
- regular floats such as: "
123.0
", "+123.0
", "-123.0
", ".123
", "123.
", "123.0e+2
", "123.0e-2
"
String[Bearbeiten]
If the pin's datatype is String
, then no leading/trailing quotes are needed
(actually: if there are quotes, these will be part of the string). However, quotes are needed if the type is not unambiguously a String type (i.e. Any or a Union type).
By default, NO C-style escape sequences are interpreted - i.e. the string is taken "as-is". If you want or need those, enable the "C-Escapes" toggle via the freeze-value's popup menu.
Bytes (ByteArray)[Bearbeiten]
Byte data can be entered in multiple forms:
- Smalltalk format: "
#[ 1 2 3 ]
" (spaces between byte values) - JSON format: "
[ 1, 2, 3 ]
" (commas between byte values) - C format: "
{ 1, 2, 3 }
" (braces and commas between byte values) - hex format: "
xxXXxxXX
" (two hex characters per byte; no spaces in-between) - hex format: "
xx XX xx XX
" (two hex characters per byte; with spaces in-between)
Any[Bearbeiten]
To distinguish between strings and non-strings, String-constants for an Any-typed pin must be quoted. For example:
- "
1234
" - will be an integer value - "
1234.56
" - will be an float value - "
'1234'
" - will be a string value
