thirdparty.builder.assistTool for automatically building code on save.Usage Synopsisassist -p <path to watch> -- <command to run>OverviewInotify (i.e. inotifywait) and other file change notification systems will send many events all at once about how a file is being accessed or changed. You can't you these raw events to trigger a build because you'd start running the build prematurely.This script is designed to watch for only mutation events (i.e. it ignores opens, accesses, and close with nowrite). When using an editor like VSCode, it is constantly accessing file meta data to determine if it needs to reread files. We should not build everytime VSCode merely reads the metadata of a file path.The script waits for the inotify events to settle before running the build again. For example, you may run a formatter that modifies many files in the source directory. You don't want the build command to be executed after only the first file has been written, you need to wait until all files have been touched. This settlement is detected with a simple timeout. It waits for a given duration of no events after an event before running the given reaction command.The script will not queue commands to run while changes are incoming. If the given command takes a while to run, changes might be made to the source while the command is running. The last change time is recorded and this is checked against the last time the command was executed. If the difference is greater than the given settlement duration it'll rerun the command.The script has a signal handler to catch Ctrl-C. Ctrl-C is the expected way to exit the watcher.py while its waiting for updates. I don't know what the behavior of the system is if you Ctrl-C/SIGINT while the given user command is being executed.Installpython3 -m pip install --upgrade thirdparty-builder-assistCLI UsageThirdparty Builder Assist includes a console scriptassist. The intended use for this is to run a file watcher for a source directory and automatically run a build and/or test command after there have been no changes to any files for 1 second.If your current working directory is/project, and this project is a make project will all source stored in/project/src, you can useassistto automatically runmakeusing a command like the following:assist -p src -- makeAPI UsageThirdparty Builder Assist comes with an API that allows your code to react to inotify events the same way theassistconsole script does. Using the same example above, here is an example Python snippet prints a message when change events are detected.from thirdparty.builder.assist import start_watching
from time import sleep

# Fire up builder.assist thread.
assist_context = start_watching('/project/src')

while True:
    sleep(0.1)
    if assist_context.is_event():
        print("Detected changes.")ContributingAny contributions and feature requests are welcome! Please submit all contributions for thirdparty.builder.assist as an issue or pull-request (PR) onthirdparty.builder.assist's Github Page.LicenseMIT License
