# Make go restart
A sample project with a Makefile to restart the go-server if the source-code changes.
# Prerequisites
* Install `inotifywait` with apt
* If on mac, substitute inotifywait with `fswatch`. See the section "Adjustments for Mac" for details.
## Usage
$ make watch
* Start watching the source-code and restarting the server with the command `make watch`.
* Stop watching with `ctrl-c`.
* Clean up temporary files with the `clean` target, `make clean`
## How does it work?
When writing a server in go, it is not possible or necessary to do partial reloads of the application during development. A restart of the process is fast enough(sub-second, typically 5-600ms).
The example in the makefile watches for file-changes with the help of `inotifywait`/`fswatch` and takes advantage of `make`s built in support for incremental builds.
The watch target when using `inotifywatch` is basically a loop that waits until there are file-changes and then triggering a build:
```
watch: clean server.PID
while true ; do \
date; \
make .restartServer ;\
inotifywait -qre close_write . ; \
done
```
See the [Makefile](Makefile) for all details.
# Adjustments for Mac
* Install fswatch , `brew install fswatch`
Change the watch-target to this:
```
watch: clean server.PID
while true ; do \
date; \
make .restartServer ;\
fswatch *.go -1 ; \
done
```
