watcher
Crystal shard to watch file changes. This shard use the same code implemented here (Guardian) and here (Sentry).
Installation
Add this to your application's shard.yml
:
dependencies:
watcher:
github: faustinoaq/watcher
Usage
Use the keyword watch
to watch files or file groups, for example:
require "watcher"
watch "src/assets/js/*.js" do |event|
event.on_change do |files|
files.each do |file, {first, timestamp}|
puts "File #{file} has changed at #{timestamp}"
end
# ...
end
end
Also you can have more than one watcher, just use spawn
spawn do
watch ["src/assets/*.css", "src/views/*.html"] do |event|
event.on_change do
# ...
end
end
end
# Other watcher
watch ... do |event|
#...
end
And you can change time interval for a watcher.
watch "public/*.json", interval: 0.5 do |event|
event.on_change do
# ...
end
end
Also you can use Watcher.watch
instead of watch
.
How does it work?
Watcher uses timestamps to check file changes every second, if you want some more advanced then you can use Watchbird that uses libnotify
to check events like modify, access and delete but just work in Linux for now.
