String manipulation functions.
This module defines several string related functions. We redefine some quite classical functions on the platforms were they are not nativaly defined (such as getline() or asprintf()), while some other are a bit more exotic.
| typedef char* xbt_string_t |
Classical alias to (char*)
This of almost no use, beside cosmetics and the XBT datadesc parsing macro (see Automatic parsing of data descriptions).
| void xbt_str_rtrim | ( | char * | s, |
| const char * | char_list | ||
| ) |
Strip whitespace (or other characters) from the end of a string.
Strips the whitespaces from the end of s. By default (when char_list=NULL), these characters get stripped:
| s | The string to strip. Modified in place. |
| char_list | A string which contains the characters you want to strip. |
| void xbt_str_ltrim | ( | char * | s, |
| const char * | char_list | ||
| ) |
Strip whitespace (or other characters) from the beginning of a string.
Strips the whitespaces from the begining of s. By default (when char_list=NULL), these characters get stripped:
| s | The string to strip. Modified in place. |
| char_list | A string which contains the characters you want to strip. |
| void xbt_str_trim | ( | char * | s, |
| const char * | char_list | ||
| ) |
Strip whitespace (or other characters) from the end and the begining of a string.
Strips the whitespaces from both the beginning and the end of s. By default (when char_list=NULL), these characters get stripped:
| s | The string to strip. |
| char_list | A string which contains the characters you want to strip. |
| xbt_dynar_t xbt_str_split | ( | const char * | s, |
| const char * | sep | ||
| ) |
Splits a string into a dynar of strings.
| s,: | the string to split |
| sep,: | a string of all chars to consider as separator. |
By default (with sep=NULL), these characters are used as separator:
| xbt_dynar_t xbt_str_split_quoted | ( | const char * | s | ) |
Splits a string into a dynar of strings, taking quotes into account.
It basically does the same argument separation than the shell, where white spaces can be escaped and where arguments are never split within a quote group. Several subsequent spaces are ignored (unless within quotes, of course). You may want to trim the input string, if you want to avoid empty entries
| xbt_dynar_t xbt_str_split_quoted_in_place | ( | char * | s | ) |
Just like xbt_str_split_quoted (Splits a string into a dynar of strings), but without memory allocation.
The string passed as argument must be writable (not const) The elements of the dynar are just parts of the string passed as argument.
To free the structure constructed by this function, free the first element and free the dynar:
free(xbt_dynar_get_ptr(dynar,0)); xbt_dynar_free(&dynar);
| xbt_dynar_t xbt_str_split_str | ( | const char * | s, |
| const char * | sep | ||
| ) |
This functions splits a string after using another string as separator For example A!!B!!C splitted after !! will return the dynar {A,B,C}.
| char* xbt_str_join_array | ( | const char *const * | strs, |
| const char * | sep | ||
| ) |
Join a set of strings as a single string.
The parameter must be a NULL-terminated array of chars, just like xbt_dynar_to_array() produces
| void xbt_str_subst | ( | char * | str, |
| char | from, | ||
| char | to, | ||
| int | occurence | ||
| ) |
Substitutes a char for another in a string.
| str | the string to modify |
| from | char to search |
| to | char to put instead |
| occurence | number of changes to do (=0 means all) |
| char* xbt_str_varsubst | ( | const char * | str, |
| xbt_dict_t | patterns | ||
| ) |
Replaces a set of variables by their values.
| str | The input of the replacement process |
| patterns | The changes to apply |
Both '$toto' and '${toto}' are valid (and the two writing are equivalent).
If the variable name contains spaces, use the brace version (ie, ${toto tutu})
You can provide a default value to use if the variable is not set in the dict by using '${var:=default}' or '${var:-default}'. These two forms are equivalent, even if they shouldn't to respect the shell standard (:= form should set the value in the dict, but does not) (BUG).
| void xbt_str_strip_spaces | ( | char * | s | ) |
Replace double whitespaces (but no other characters) from the string.
The function modifies the string so that each time that several spaces appear, they are replaced by a single space. It will only do so for spaces (ASCII 32, 0x20).
| s | The string to strip. Modified in place. |
| char* xbt_str_from_file | ( | FILE * | file | ) |
creates a new string containing what can be read on a fd
