|
|
// This package contains functions for efficiently performing string
|
|
// substitutions using a format string with positional notation:
|
|
// `Substitute()` and `SubstituteAndAppend()`.
|
|
//
|
|
// Unlike printf-style format specifiers, `Substitute()` functions do not need
|
|
// to specify the type of the substitution arguments. Supported arguments
|
|
// following the format string, such as strings, string_views, ints,
|
|
// floats, and bools, are automatically converted to strings during the
|
|
// substitution process. (See below for a full list of supported types.)
|
|
//
|
|
// `Substitute()` does not allow you to specify *how* to format a value, beyond
|
|
// the default conversion to string. For example, you cannot format an integer
|
|
// in hex.
|
|
//
|
|
// The format string uses positional identifiers indicated by a dollar sign ($)
|
|
// and single digit positional ids to indicate which substitution arguments to
|
|
// use at that location within the format string.
|
|
//
|
|
// A '$$' sequence in the format string causes a literal '$' character to be
|
|
// output.
|
|
//
|
|
// Example 1:
|
|
// std::string s = Substitute("$1 purchased $0 $2 for $$10. Thanks $1!",
|
|
// 5, "Bob", "Apples");
|
|
// EXPECT_EQ("Bob purchased 5 Apples for $10. Thanks Bob!", s);
|
|
//
|
|
// Example 2:
|
|
// std::string s = "Hi. ";
|
|
// SubstituteAndAppend(&s, "My name is $0 and I am $1 years old.", "Bob", 5);
|
|
// EXPECT_EQ("Hi. My name is Bob and I am 5 years old.", s);
|
|
//
|
|
// Supported types:
|
|
// * absl::string_view, std::string, const char* (null is equivalent to "")
|
|
// * int32_t, int64_t, uint32_t, uint64_t
|
|
// * float, double
|
|
// * bool (Printed as "true" or "false")
|
|
// * pointer types other than char* (Printed as "0x<lower case hex string>",
|
|
// except that null is printed as "NULL")
|
|
//
|
|
// If an invalid format string is provided, Substitute returns an empty string
|
|
// and SubstituteAndAppend does not change the provided output string.
|
|
// A format string is invalid if it:
|
|
// * ends in an unescaped $ character,
|
|
// e.g. "Hello $", or
|
|
// * calls for a position argument which is not provided,
|
|
// e.g. Substitute("Hello $2", "world"), or
|
|
// * specifies a non-digit, non-$ character after an unescaped $ character,
|
|
// e.g. "Hello $f".
|
|
// In debug mode, i.e. #ifndef NDEBUG, such errors terminate the program.
