Flor should support any UTF-8 string. String literals are expressed between quotes or double quotes.
There is no facility for multiline strings. Big literal strings could get in the way of terse process definitions.
'this is a single quote string.'
Single quoted strings do not allow for the "dollar notation". The following strings is taken literally:
'Responsible person: $(user.name) ($(user.age))'
Double quoted strings allow for the "dollar notation".
"Responsible person: $(user.name) ($(user.age))"
As seen above the dollar notation lets one insert flor code inside of double quoted strings. The result of the evaluation of this code is turned into a string an intertwined in the host string.
set text0 "Responsible person: $(users.0.name) ($(users.0.age))"
set text1 "Team size: $(length users)"
See dollar_spec.rb.
The + procedure can be used to concatenate strings.
+ "he" "lo" # yields "hello"
# or
"he" + "lo"
Adding a string to a number yields an error.
+ 1 "lo" # fails...
If the first operand to a + is a string, then all subsequent operands are turned into strings and the result is the concatenation of all the strings.
+ '' 1 true [ 1 2 ] # yields "1true[1, 2]"
