◆ ruby_glob_func
typedef int ruby_glob_func(const char *path, VALUE arg, void *enc) |
Type of a glob callback function.
Called every time glob scans a path.
- Parameters
-
[in] | path | The path in question. |
[in] | arg | The argument passed to rb_glob(). |
[in] | enc | Encoding of the path. |
- Return values
-
-1 | Not enough memory to do the operation. |
0 | Operation successful. |
otherwise | Opaque exception state. |
- Note
- You can use rb_protect() to generate the return value.

◆ rb_glob()
void rb_glob |
( |
const char * |
pattern, |
|
|
void(*)(const char *path, VALUE arg, void *enc) |
func, |
|
|
VALUE |
arg |
|
) |
| |
The "glob" operator.
Expands the given pattern against the actual local filesystem, then iterates over the expanded filenames by calling the callback function.
- Parameters
-
[in] | pattern | A glob pattern. |
[in] | func | Identical to ruby_glob_func, except it can raise exceptions instead of returning opaque state. |
[in] | arg | Extra argument passed to func. |
- Exceptions
-
rb_eException | Can propagate what func raises. |
- Note
- The language accepted as the pattern is not a regular expression. It resembles shell's glob.
◆ ruby_brace_glob()
Identical to ruby_glob(), @shyouhei currently suspects.
Historically you had to call this function instead of ruby_glob() if the pattern included "{x,y,...}" syntax. However since commit 0f63d961169989a7f6dcf7c0487fe29da, ruby_glob() also supports that syntax. It seems as of writing these two functions provide basically the same functionality in a different implementation. Is this analysis right? Correct me! :FIXME:
- Parameters
-
[in] | pattern | A glob pattern. |
[in] | flags | No, you are not allowed to use this. Just pass 0. |
[in] | func | A callback function. |
[in] | arg | Extra argument passed to func. |
- Returns
- Return value of
func
.
