Single quotes are used for single ascii characters, eg 'A'. Multibyte unicode characters are typically held as utf-8 strings.<br>
Double quotes are used for single-line [http://phix.x10.mx/docs/html/strings.htm strings], with backslash interpretation, eg "one\ntwo\nthree\n".<br>
Line 192 ⟶ 193:
Phix does not support interpolation other than printf-style, eg printf(1,"Hello %s,\nYour account balance is %3.2f\n",{name,balance}).<br>
Back-ticks and triple-quotes are used for multi-line strings, without backslash interpretation, eg
<!--<lang Phix>-->
one▼
<span style="color: #008080;">constant</span> <span style="color: #000000;">t123</span> <span style="color: #0000FF;">=</span> <span style="color: #008000;">`
two▼
▲ one
three▼
▲ two
`</lang>▼
▲ three
`</span>
or (entirely equivalent, except the following can contain back-ticks which the above cannot, and vice versa for triple quotes)
<!--<lang Phix>-->
one▼
<span style="color: #008080;">constant</span> <span style="color: #000000;">t123</span> <span style="color: #0000FF;">=</span> <span style="color: #008000;">"""
two▼
▲ one
three▼
▲ two
"""</lang>▼
▲ three
<!--</lang>-->
Both are also equivalent to the top double-quote one-liner. Note that a single leading '\n' is automatically stripped.<br>
Several builtins such as [http://phix.x10.mx/docs/html/substitute.htm substitute], [http://phix.x10.mx/docs/html/split.htm split], and [http://phix.x10.mx/docs/html/join.htm join] are often used to convert such strings into the required internal form.<br>
Regular expressions are usually enclosed in back-ticks, specifically to avoid backslash interpretation.<br>
You can also declare hexadecimal strings, eg
<!--<lang Phix>-->
-- note however it displays as {1,2,52,86,120,171,12}▼
<span style="color: #000000;">x</span><span style="color: #008000;">"1 2 34 5678_AbC"</span> <span style="color: #000080;font-style:italic;">-- same as {0x01, 0x02, 0x34, 0x56, 0x78, 0xAB, 0x0C}
-- whereas x"414243" displays as "ABC" (as all chars)</lang>▼
▲ -- note however it displays as {1,2,52,86,120,171,12}
<!--</lang>-->
Literal [http://phix.x10.mx/docs/html/sequences.htm sequences] are represented with curly braces, and can be nested to any depth, eg
<lang Phix>{2, 3, 5, 7, 11, 13, 17, 19}
