gchar * exo_str_elide_underscores (const gchar *text
);
Returns a copy of text
with all mnemonic underscores
stripped off.
|
A zero terminated string. |
Returns : |
A copy of text without underscores. The returned string
must be freed when no longer required. |
gboolean exo_str_is_equal (const gchar *a
,const gchar *b
);
NULL
-safe string comparison. Returns TRUE
if both a
and b
are
NULL
or if a
and b
refer to valid strings which are equal.
You should always prefer this function over strcmp()
.
#define exo_str_is_empty(string)
Macro to check if a string is NULL
or empty. You should prefer
this function over strlen (str) == 0.
gboolean exo_str_looks_like_an_uri (const gchar *str
);
Check if str
looks like an uri. This function is no guarantee that
the uri exists, or is supported by the system.
|
an input string. |
Returns : |
TRUE if the str looks like an URI
according to RFC 2396, FALSE otherwise. |
Since 0.5.0
gchar * exo_str_replace (const gchar *str
,const gchar *pattern
,const gchar *replacement
);
Searches str
for occurances of pattern
and replaces each
such occurance with replacement
. Returns a newly allocated
copy of str
on which the given replacement were performed.
The caller is responsible to free the returned string using
g_free()
when no longer needed.
Note that pattern
and replacement
don't need to be of the
same size. If replacement
is NULL
, the pattern will be
removed from the string.
|
the input string. |
|
a search pattern in str . |
|
replacement string for pattern . |
Returns : |
a newly allocated copy of str where all occurances of
pattern are replaced with replacement . Or NULL if
str and/or pattern is NULL . |
Since 0.3.1.1
gchar * exo_strdup_strftime (const gchar *format
,const struct tm *tm
);
Cover for standard date-and-time-formatting routine strftime that returns
a newly-allocated string of the correct size. The caller is responsible
to free the returned string using g_free()
when no longer needed.
Besides the buffer management, there are two differences between this and the library strftime:
The modifiers "-" and "_" between a "%" and a numeric directive are defined as for the GNU version of strftime. "-" means "do not pad the field" and "_" means "pad with spaces instead of zeroes".
Non-ANSI extensions to strftime are flagged at runtime with a warning, so it's easy to notice use of the extensions without testing with multiple versions of the library.
|
format string to pass to strftime(3). See the strftime(3) documentation for details. |
|
date/time, in struct tm format. |
Returns : |
a newly allocated string containing the formatted date/time. |
Since 0.3.3
gchar ** exo_strndupv (gchar **strv
,guint num
);
Creates a new string vector containing the first n
elements
of strv
. If called on a NULL
value or num
is 0, exo_strndupv()
simply returns NULL
.
|
String vector to duplicate. |
|
Number of strings in strv to duplicate. |
Returns : |
A new NULL-terminated array of strings or NULL .
Should be freed using g_strfreev() when no longer needed. |
#define I_(string)
Shortcut for g_intern_static_string()
to return a
canonical representation for string
.
|
A static string. |
Returns : |
a canonical representation for the string. Since : 0.3.1.1 |
