iproute

A library to parse output of iproute2 using EBNF grammar

Usage

;; ip rule / ip route list table all
(def samples "10.8.0.32 dev tun11  proto kernel  scope link  src 10.8.0.31
  169.254.0.0/16 dev eth0  proto kernel  scope link  src 169.254.70.142
  fe80::/64 dev eth1  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
  127.0.0.0/8 dev lo  scope link")
  
(iproute.route/parse samples)

;; ip route get 192.168.0.101
(def sample-route-get

(iproute.route/parse sample-route-get)

;; ip rule
(def rule-samples "0:	from all lookup local

(iproute.rule/parse rule-samples)

REPL Development

Development runs only java-8 due rewrite-clj oddity

lein trampoline run -m rebel-readline.main
(require '[cljsh.repl :refer [save defnc defc]]) (use 'aprint.core) (use 'cljsh.namespaces) (use 'cljsh.deps) (use 'com.rpl.specter) (require 'cljsh.complement) (cljsh.complement/patch) (use 'cljsh.inspect) (require 'cljsh.utils) (require '[cljsh.source :refer [source-expand-ns]]) (require '[clojure.java.io :as io]) (use 'clojure.tools.trace)

Tests

(use 'eftest.runner)
(run-tests (find-tests "test"))
