Every time I push further, they continually surprise me with how much they are able to let you set database actions in a pipeline. Map.new(changeset.I've been pushing Ecto.Multis further and further recently, trying to see what I can get out of them.

If entr were to close its own file descriptor to STDIN, there is no reliable and immediate way to determine when the child has terminated in order to restore keyboard input. The -r flag cannot be used with an interactive task.Ĭlosing STDIN on the child allows entr to accept keyboard input. setup.py)Įntr has several implementation details, such as: Watching for new files in a directory ($ ls -d src/*.py | entr -d. Restarting services with a timeout ($ ls app | entr -r timeout -k 5 0. Starting a server block until any of the listed files change ($ ls *.rb | entr -r ruby main.rb) Running tests if the build was successful ($ ls | entr -s 'make & make test') Rebuilding a project if sources change ($ ls | entr make) Users can extend and enhance the capabilities of this shortcut by emulating rsync orĮntr can be used in various ways, such as: Processes files in a specific way, such as monitoring one file at a time using the /_ shortcut. Entr has some architectural limitations, such as not being able to use the -r flag with an interactive task, and closing STDIN to raise an error instead. The directory watch option (-d) was added to react to events when a new file is added to aĭirectory. The restart option starts the utility as a background process thatĭoes not have access to STDIN, allowing keyboard input to be provided using a FIFO. Entr can recognize files by their contents and skip directories such as.
