Name Mangler is free to download and try out, and it’s payware if you decide to have the full feature set, costing about $10. * Add a Prefix or Suffix (Filename.jpg to Filename-trip.jpg)

* Change Case (caps to lowercase, vice versa) * Number Sequentially (file1, file2, file3) * Find and Replace (find all instances of Blah in filename_Blah and replace with Wow) For example, take a look at the function's local variable seq: Each new call to the function injects a value incremented by one into the modified file name.Name Mangler goes beyond just renaming something from file1 to file2 though, there are many more advanced batch renaming capabilities including some of the following types of situations:

It replaces all matches that match the expression in the original name org with the replacement string stored in repl.Īttentive readers may wonder about the mkmodifier() function in Listing 3: It returns a function to the main program, to be called multiple times, but this function actually seems to maintain state between calls. After that, the modifier defined in line 27 can call the ReplaceAllString() function. To enable this, Listing 3 draws on the standard regexp package and compiles the regular expression from the user input to create a rex variable of the *regexp.Regexp type using MustCompile() in line 25. log suffix must actually be at the end of the name – it would ignore. log$ search expression illustrated earlier specifies that the. Instead of requesting a plain vanilla string replacement, the user can also specify regular expressions to remodel file names. The associated if block prints a message and breaks the for loop with break, because in that case the end of the world is nigh. If access rights prevent this, the function fails and os.Rename() returns an error, which line 53 fields. In production mode, however, line 52 calls the Unix system rename() function from the standard os package and renames the file to the new name from modfile. If the user has chosen dryrun mode ( -d), line 47 simply prints the intended rename action, and line 50 rings in the next round of the for loop with continue, skipping the call of rename() in line 52. With every call, the main program passes the returned file name the original name of the file and, in line 42, picks up the new name and stores it in modfile. A few lines down, in the for loop that iterates over all the files to be manipulated, the main program simply calls this function by referencing modifier. You've read that correctly: The mkmodifier() function actually returns a function in line 34 of Listing 2, which is assigned to the modifier variable there.
