+# Funlen linter
+
+Funlen is a linter that checks for long functions. It can checks both on the number of lines and the number of statements.
+
+The default limits are 50 lines and 35 statements. You can configure these with the `-l` and `-s` flags.
+
+Example code:
+
+```go
+package main
+
+import "fmt"
+
+func fiveStatements() {
+    fmt.Println(1)
+    fmt.Println(2)
+    fmt.Println(3)
+    fmt.Println(4)
+    fmt.Println(5)
+}
+
+func sevenLines() {
+    fmt.Println(1)
+
+    fmt.Println(2)
+
+    fmt.Println(3)
+
+    fmt.Println(4)
+}
+```
+
+Reults in:
+
+```
+$ funlen -l=6 -s=4 .
+main.go:5:6:Function 'fiveStatements' has too many statements (5 > 4)
+main.go:13:6:Function 'sevenLines' is too long (7 > 6)
+```
+
+## Installation guide
+
+```bash
+go get git.ultraware.nl/NiseVoid/funlen
+```
+
+### Gometalinter
+
+You can add funlen to gometalinter and enable it.
+
+`.gometalinter.json`:
+
+```json
+{
+	"Linters": {
+		"funlen": "funlen -l=50 -s=35:PATH:LINE:COL:MESSAGE"
+	},
+
+	"Enable": [
+		"funlen"
+	]
+}
+```
+
+commandline:
+
+```bash
+gometalinter --linter "funlen:funlen -l=50 -s=35:PATH:LINE:COL:MESSAGE" --enable "funlen"
+```
