![]() ![]() Working with arguments in auto event selection only. ![]() Add the "Wait for file process to finish" option.Can monitor up to four folders simultaneously (registered version only).The registered version is distributed in a single ZIP archive file without installation, it is portable and can be moved and executed from any location on the same computer, but can't be executed from a different computer (registration is per machine).Ĭhanges from last published version (2.3): Registered version – this version let you monitor up to four folders simultaneously.The free version is distributed as portable app without installation and can be moved and executed from a different location or different computer. Free version – this version is limited to a single folder monitoring, which means you can monitor only one folder at a time, this version if free to download and use with no other limitations.W4F can run in the background from the system tray and use minimum resources and can auto start with different configurations using command line parameters. The program maintains a live log that logs every event, action or settings changes. W4F can also return the changed object (file, folder, etc.) as an argument to the executed program batch or script so you can predefine automation process for this object, for example you can monitor a folder for new files and when a new file is created you can print the new file or move the file to a different location, open it with a program you want or any other manipulation you need. It can also react for each event with different kind of actions like writing to a log file, display different kind of messages or executing a program, batch or script. So, let’s start creating four different functions that will be used when a file is modified, created, deleted or moved.Watch 4 Folder 2.5 - a folder monitoring and automation utility that can monitor up to 4 different folders simultaneously for 12 kinds of events and react for each event with different kind of actions. Now that we have created the handler we need to write the code we want to run when the events are raised. The “patterns” variable contains the file patterns we want to handle (in my scenario, I will handle all the files), the “ignore_patterns” variable contains the patterns that we don’t want to handle, the “ignore_directories” is just a boolean that we can set to True if we want to be notified just for regular files (not for directories) and the “case_sensitive” variable is just another boolean that, if set to “True”, made the patterns we previously introduced “case sensitive” (that’s normally a good idea, unless you are working with stupid case-insensitive-file-systems… yeah, I’m talking about you Windows! :P ). In my example I have used some variables just to made the configuration of the event handler a little bit easier to be undestood. If _name_ = "_main_" : patterns = ignore_patterns = None ignore_directories = False case_sensitive = True my_event_handler = PatternMatchingEventHandler ( patterns, ignore_patterns, ignore_directories, case_sensitive ) Now, create your virtual environment (optional but raccomended… at least by me), activate it and install the package watchdog with the following command: If you want to find out more about virtual environments (that’s probabilly because you haven’t read all my previous post, so shame on you!), just have a look at this article. As always, I raccomand to use virtual environments instead of installing packages system wide. To code this program we will need an additional module called “watchdog” (wow, who could have guessed it?) written by Yesudeep Mangalapilly, so let’s start by installing it. So, today we will code a watchdog in Python. Your program could set a watchdog to monitor that file and if the configuration file is modified you could think to reload it and apply the new configuration at runtime, without the need of restarting your program. When a change occurs, the watchdog report it to us raising a specific event that we can handle.įor example, let’s suppose you have developed a program that use a configuration file. But what is a “watchdog”?Ī watchdog is a little piece of software that monitors our filesystem looking for any changes (like the creation, change or deletion of a file or of a directory). Hey guys, today’s post is about how to create a watchdog in Python. How to create a watchdog in Python to look for filesystem changes ![]()
