![]() ![]() This is definitely a user-friendly way of doing things in a point and click environment. We're used to interacting with that file through something like Mac's Finder or Windows' File Explorer, where we click our way to the file, navigating through folders as if they were "places". Let's pretend we have a folder on our Desktop called "myVideos", that contains a movie file called "Graduation.mp4". So, what is a path? A path is essentially a location on your file system, aka the name of a file or folder. This chapter's goal is bring you up to speed on how files are named programmatically, allowing you easily open and save files from your scripts, and understand any errors when you've made a mistake. ![]() I'm under the impression that with more recent upgrades of Praat some of this has been made easier. Maybe you've had the experience of trying to get a script to open or write a file, and been driven mad with a "File not found" error. until all files in the list are processed.I personally found paths to be a big pain in the kiester when I first started programming and programming for Praat. It provides an index, starting with 1, which is incremented by 1 until the number of files is reached, i.e. What we need: Incremental processing of all files referenced in the file list.įirst the number of filenames in the list must be determined to find out the number of passes through the loop. What we have: A list of filenames, referencing files in a given directory. What we can do now, however, is pondering over an abstract algorithm, so that the structure of the script is ready for implementation as soon as we're able to use loops. We have to put off implementation of this step until we finish discussing loops in the next session. Step 2 of batch processing involves looping through the file list which we created in step 1. of files located in the working directory.containing a list of all filenames ending with.creates a Strings object called Filelist.Having unraveled the mechanism of file list creation, implementation is straightforward:Ĭreate Strings as file list: "Filelist", "*.wav" To practice file list creation and become familiar with filename patterns using a wildcard, select New > Create Strings as file list., try different patterns in the File path input field, click apply, and review the resulting list with View & Edit. Lists created with Create Strings as file list contain only filenames, the path information is not part of the list! * → Only the first asterisk is interpreted as a wildcard, additional asterisks are interpreted as literal characters! wavĪll filenames starting with item, followed by any number of arbitrary characters, followed by. Some examples:Īll filenames starting with item and ending with. Instead of listing all files or only one file, the range of target files can be restricted with a wildcard: The asterisk (*) is a joker matching any character. ![]()
