Functions
Print and Format Functions
Utility functions for formatted output and string creation. These functions provide flexible printing to output streams and string formatting with support for variadic arguments and placeholder-based formatting using "{}" syntax.

	Outputs a single argument to the specified stream.
template<typename T , typename... Targs>
void	tec::print (std::ostream *out, const char *fmt, const T &value, Targs &&... Args)
	Outputs variadic arguments to the specified stream with formatting.
template<typename T >
void	tec::println (std::ostream *out, const T &arg)
	Outputs a single argument to the specified stream with a newline.

format() [1/2]

template<typename T , typename... Targs>

std::string tec::format	(	const char *	fmt,
		const T &	value,
		Targs &&...	Args
	)

Formats variadic arguments into a string.

Processes a format string with "{}" placeholders, replacing each placeholder with the corresponding argument, and returns the resulting string.

Template Parameters

T	The type of the first argument.
Targs	The types of additional arguments.

Parameters

fmt	The format string containing "{}" placeholders.
value	The first argument to format.
Args	The remaining arguments to format.

Returns

std::string The formatted string.

format() [2/2]

template<typename T >

std::string tec::format

(

const T &

arg

)

Formats a single argument into a string.

Converts the provided argument to its string representation using an output stream.

Template Parameters

T	The type of the argument to format.

Parameters

arg	The argument to format.

Returns

std::string The string representation of the argument.

print() [1/4]

template<typename T , typename... Targs>

void tec::print	(	const char *	fmt,
		const T &	value,
		Targs &&...	Args
	)

Outputs variadic arguments to std::cout with formatting.

Processes a format string with "{}" placeholders, replacing each placeholder with the corresponding argument, outputting to the standard output stream.

Template Parameters

T	The type of the first argument.
Targs	The types of additional arguments.

Parameters

fmt	The format string containing "{}" placeholders.
value	The first argument to output.
Args	The remaining arguments to output.

print() [2/4]

template<typename T >

void tec::print

(

const T &

arg

)

Outputs a single argument to std::cout.

Writes the provided argument to the standard output stream without formatting.

Template Parameters

T	The type of the argument to output.

Parameters

arg	The argument to output.

print() [3/4]

template<typename T , typename... Targs>

void tec::print	(	std::ostream *	out,
		const char *	fmt,
		const T &	value,
		Targs &&...	Args
	)

Outputs variadic arguments to the specified stream with formatting.

Processes a format string with "{}" placeholders, replacing each placeholder with the corresponding argument. Recursively handles multiple arguments.

Template Parameters

T	The type of the first argument.
Targs	The types of additional arguments.

Parameters

out	Pointer to the output stream (e.g., std::cout or std::ostringstream).
fmt	The format string containing "{}" placeholders.
value	The first argument to output.
Args	The remaining arguments to output.

print() [4/4]

template<typename T >

void tec::print	(	std::ostream *	out,
		const T &	arg
	)

Outputs a single argument to the specified stream.

Writes the provided argument to the given output stream without any formatting.

Template Parameters

T	The type of the argument to output.

Parameters

out	Pointer to the output stream (e.g., std::cout or std::ostringstream).
arg	The argument to output.

println() [1/4]

template<typename T , typename... Targs>

void tec::println	(	const char *	fmt,
		const T &	value,
		Targs &&...	Args
	)

Outputs variadic arguments to std::cout with formatting and a newline.

Processes a format string with "{}" placeholders, replacing each placeholder with the corresponding argument, outputting to the standard output stream, and appending a newline.

Template Parameters

T	The type of the first argument.
Targs	The types of additional arguments.

Parameters

fmt	The format string containing "{}" placeholders.
value	The first argument to output.
Args	The remaining arguments to output.

println() [2/4]
