StringForm["controlstring",expr1,…]

prints as the text of the controlstring, with the printed forms of the expri embedded.

Details

  • `i` in the control string indicates a point at which to print expri.
  • `` includes the next expri not yet printed.
  • `.` prints a raw ` in the output string. »
  • You can use StringForm to set up "formatted output".
  • Messages given as values for objects of the form s::t are used as control strings for StringForm.

Basic Examples  (3)

Insert a single value into a string:

Wolfram Language code: StringForm["The value of x is ``.", 5]

Insert a sequence of values into a string:

Wolfram Language code: StringForm["The values are x=`` and y=``.", 5, 10]

Insert indexed values:

Wolfram Language code: StringForm["The values are x=`2` and y=`1`.", 10, 5]

Scope  (4)

Embed a symbolic result:

Wolfram Language code: StringForm["The integral result is ``.", Integrate[x, x]]

Embed an unevaluated symbolic expression:

Wolfram Language code: StringForm["The integral is ``.", HoldForm[Integrate[x, x]]]

Include an explicit ` character in a string:

Wolfram Language code: StringForm["The symbol `` is defined in the Global`.` context.", x]

Insert any number of expressions into a string:

Wolfram Language code: StringForm["`` `` `` `` ``", e1, e2, e3, e4, e5]

Expressions can be inserted in the output string more than once:

Wolfram Language code: StringForm["{`1`,`2`,`1`,`1`,`2`}", e1, e2]

Properties & Relations  (1)

StringForm prints as a string with items inserted as output:

Wolfram Language code: s::t = "A string with inputs `1` and `2`.";
Wolfram Language code: StringForm[s::t, e1, e2]

Message prints a string with items inserted:

Wolfram Language code: Message[s::t, e1, e2]

StringInsert inserts a string into a string:

Wolfram Language code: StringInsert[StringInsert["A string with inputs and .", "e1", -7], "e2", -2]

Possible Issues  (1)

There should be enough items to fill the placeholders in the control string:

Wolfram Language code: StringForm["A string with inputs `1` and `2`.", e1]
