Developer Guide
The new livereload server is designed for developers. It can power a wsgi application now:
from livereload import Server, shell
server = Server(wsgi_app)
# run a shell command
server.watch('static/*.stylus', 'make static')
# run a function
def alert():
print('foo')
server.watch('foo.txt', alert)
# output stdout into a file
server.watch('style.less', shell('lessc style.less', output='style.css'))
server.serve()
The Server class accepts parameters:
app: a wsgi application
watcher: a watcher instance, you don’t have to create one
server.watch
server.watch can watch a filepath, a directory and a glob pattern:
server.watch('path/to/file.txt')
server.watch('directory/path/', delay=5)
server.watch('glob/*.pattern')
You can also use other library (for example: formic) for more powerful file adding:
for filepath in formic.FileSet(include="**.css"):
server.watch(filepath, 'make css')
