These functions provide string buffer management.

The String Buffer data type is designed to be a mutable string, allowing the appending, prepending or insertion of a string to a buffer.

For more information see this example.

Typedef Documentation

Eina_Strbuf

Type for a string buffer.

Function Documentation

Eina_Bool eina_strbuf_append	(	Eina_Strbuf *	buf,
		const char *	str
	)

Appends a string to a buffer, reallocating as necessary.

Parameters:

[in,out]	buf	The string buffer.
[in]	str	The string to append.

Returns:: EINA_TRUE on success, EINA_FALSE on failure such as if str could not be appended.

This function appends str to buf. It computes the length of str, so is slightly slower than eina_strbuf_append_length(). If the length is known beforehand, consider using that variant.

See also:: eina_strbuf_append(); eina_strbuf_append_length()

Since :: 2.3

Examples:: entry_example.c.

Eina_Bool eina_strbuf_append_buffer	(	Eina_Strbuf *	buf,
		const Eina_Strbuf *	data
	)

Appends an Eina_Strbuf to a buffer, reallocating as necessary.

Parameters:

[in,out]	buf	The string buffer.
[in]	data	The string buffer to append.

Returns:: EINA_TRUE on success, EINA_FALSE if data could not be appended.

This function appends data to buf. data must be allocated and different from NULL. It is slightly faster than eina_strbuf_append() as it does not compute the size of str.

Eina_Bool eina_strbuf_append_char	(	Eina_Strbuf *	buf,
		char	c
	)

Appends a character to a string buffer, reallocating as necessary.

Parameters:

[in,out]	buf	The string buffer.
[in]	c	The character to append.

Returns:: EINA_TRUE on success, EINA_FALSE if c could not be appended.

This function appends c to buf.

Appends an escaped string to a buffer, reallocating as necessary.

Parameters:

[in,out]	buf	The string buffer.
[in]	str	The string to append.

Returns:: EINA_TRUE on success, EINA_FALSE if str could not be appended.

Eina_Bool eina_strbuf_append_length	(	Eina_Strbuf *	buf,
		const char *	str,
		size_t	length

Appends a string of exact length to a buffer, reallocating as necessary.

Parameters:

[in,out]	buf	The string buffer.
[in]	str	The string to append.
[in]	length	The exact length to use.

Returns:: EINA_TRUE on success, EINA_FALSE if str could not be appended.

This function appends str to buf. str must be of size at most length. It is slightly faster than eina_strbuf_append() as it does not compute the size of str. It is useful when dealing with strings of known size, such as eina_stringshare.

Parameters:

[in,out]	buf	The string buffer.
[in]	str	The string to append.
[in]	maxlen	The maximum number of characters to append.

Returns:: EINA_TRUE on success, EINA_FALSE if str could not be appended.

This function appends at most maxlen characters of str to buf. It can't append more than the length of str. It computes the length of str, so it is slightly slower than eina_strbuf_append_length().

		const char *	str,
		const char *	with,
		unsigned int	n
	)

Replaces a substring in the buffer with another string.

Parameters:

[in,out]	buf	The string buffer.
[in]	str	The text to match.
[in]	with	The replacement string.
[in]	n	The indexed occurrence to be replaced.

Returns:: EINA_TRUE on success, EINA_FALSE on failure.

This function replaces the n-th occurrence of str in buf with with.

Since :: 2.3

int eina_strbuf_replace_all	(	Eina_Strbuf *	buf,
		const char *	str,
		const char *	with
	)

Replaces all matching substrings with another string.

Parameters:

[in,out]	buf	The string buffer.
[in]	str	The text to match.
[in]	with	The replacement string.

Returns:: Number of replacements made, or 0 on failure.

This function replaces all the occurrences of str in buf with the string with.

Since :: 2.3

Examples:: eina_strbuf_01.c.

Eina_Bool eina_strbuf_replace_last	(	Eina_Strbuf *	buf,
		const char *	str,
		const char *	with
	)

Replaces the last occurrence of a substring with another string.

Parameters:

[in,out]	buf	The string buffer.
[in]	str	The text to match.
[in]	with	The replacement string.

Returns:: EINA_TRUE on success, EINA_FALSE on failure.

This function replaces the last occurrence of str in buf with with.

void eina_strbuf_reset ( Eina_Strbuf * buf )

Resets a string buffer.

Parameters:

[in,out] buf The string buffer.

This function resets buf: the buffer len is set to 0, and the string data is set to '\0'. No memory is freed.

Since :: 2.3

Examples:: eina_strbuf_01.c.

void eina_strbuf_rtrim ( Eina_Strbuf * buf )

Right trims the string buffer.

Parameters:

[in,out] buf The string buffer.

This function removes whitespace at the end of the buffer's string.

Since :: 2.3

Eina_Rw_Slice eina_strbuf_rw_slice_get ( const Eina_Strbuf * buf )

Gets a read-write slice of the buffer contents.

Parameters:

[in] buf The string buffer.

Returns:: A read-write slice for the current contents. It may become invalid as soon as the buf is changed, such as through calls like eina_strbuf_append() or eina_strbuf_remove().

Since (EFL) :: 1.19.0

Eina_Slice eina_strbuf_slice_get ( const Eina_Strbuf * buf )

Gets a read-only slice of the buffer contents.

Parameters:

[in] buf The string buffer.

Returns:: A read-only slice of the current contents. It may become invalid as soon as buf is changed.

Since (EFL) :: 1.19

void eina_strbuf_string_free ( Eina_Strbuf * buf )

Frees the contents of a string buffer but not the buffer.

Parameters:

[in,out] buf The string buffer.

This function frees the string contained in buf without freeing buf.

Since :: 2.3

const char* eina_strbuf_string_get ( const Eina_Strbuf * buf )

Retrieves a pointer to the contents of a string buffer.

Parameters:

[in] buf The string buffer.

Returns:: The current string in the string buffer.

This function returns the string contained in buf. The returned value must not be modified and will no longer be valid if buf is modified. In other words, calling eina_strbuf_append() or similar functions will make this pointer invalid. The pointer returned by this function must not be freed.

Since :: 2.3

Examples:: eina_strbuf_01.c, and entry_example.c.

char* eina_strbuf_string_steal ( Eina_Strbuf * buf )

Steals the contents of a string buffer.

Parameters:

[in,out] buf The string buffer.

Returns:: The string that was contained in buf.

This function returns the string contained in buf. buf is then initialized and does not own the returned string anymore. The caller must release the memory of the returned string by calling free().

See also:: eina_strbuf_string_get()

Since :: 2.3

void eina_strbuf_tolower ( Eina_Strbuf * buf )

Converts the string to lower case.

Parameters:

[in,out] buf The string buffer.

This function converts all the characters in the buffer's string to lower case.

Since (EFL) :: 1.17

Since :: 3.0

Examples:: eina_strbuf_01.c.

void eina_strbuf_trim ( Eina_Strbuf * buf )

Trims the string buffer.

Parameters:

[in,out] buf The string buffer.

This function removes whitespace at the beginning and end of the buffer's string.

Since :: 2.3
