# fmthandler
fmthandler is a tool that enhances Go HTTP server code by automatically adding logging to HTTP HandlerFunc handlers.
It parses the Abstract Syntax Tree (AST) of your code to achieve this.
### Features
- Automatically adds logging statements to HTTP HandlerFunc handlers.
- Works seamlessly with both single files and entire directories of Go code.
## Installation
```shell
go install github.com/behnambm/fmthandler@latest
```
### Code Before
```go
package main
import (
"log"
"net/http"
)
func main() {
http.HandleFunc("/ping", func(w http.ResponseWriter, r *http.Request) {
w.WriteHeader(200)
w.Write([]byte("pong"))
})
err := http.ListenAndServe(":9090", nil)
if err != nil {
log.Fatalln(err)
}
}
```
### Running the fmthanlder
```shell
fmthandler --file main.go
```
### Code After
```go
package main
import (
"fmt"
"log"
"net/http"
)
func main() {
http.HandleFunc("/ping", func(w http.ResponseWriter, r *http.Request) {
fmt.Println("Invoking HandlerFunc: '/ping'")
w.WriteHeader(200)
w.Write([]byte("pong"))
})
err := http.ListenAndServe(":9090", nil)
if err != nil {
log.Fatalln(err)
}
}
```
