# eventer
Event emitter and listener in R.
## Installation
You can install the development version of eventer like so:
``` r
# install.packages("remotes")
remotes::install_github("JohnCoene/eventer")
```
## Example
This is a basic example which shows you how to solve a common problem:
``` r
library(eventer)
listener1 <- function(...) {
cat("Listener 1 received:", ..., "\n")
}
listener2 <- function(...) {
cat("Listener 2 received:", ..., "\n")
}
# instantiate
e <- event()
# register listeners
e$on("event1", listener1)
e$on("event1", listener2)
e$on("event2", listener1)
# emit events
e$emit("event1", "Hello", "World")
e$emit("event2", "Another", "Event")
# will not trigger on, listener is unregistered
e$off("event1", listener2)
e$emit("event1", "Hello again")
```
