+ | ======Synopsis: | ||
+ | $__which__(%%< | ||
+ | |||
+ | ======Technical: | ||
+ | The %%< | ||
+ | from most functions. | ||
+ | |||
+ | This function returns the full pathname of the specified filename. | ||
+ | function will search the client' | ||
+ | file. In addition, a list of colon-delimited directories may be specified, | ||
+ | which will be searched if the file is not found in the [[set load | ||
+ | path|LOAD_PATH]]. | ||
+ | |||
+ | ======Practical: | ||
+ | This function tries to find the location of a particular file. This makes it | ||
+ | suitable for [[LOAD]] and [[STUB]] commands, allowing a file to be loaded, even | ||
+ | if its exact location is not known. | ||
+ | |||
+ | ======Returns: | ||
+ | the canonical path of the file, or nothing if it isn't found | ||
+ | |||
+ | ======Examples: | ||
+ | < | ||
+ | $which(some_file) | ||
+ | $which(does_not_exist) | ||
+ | $which(some_file /bin) search in /bin for some_file too | ||
