Graphd testing

First build it:

{•̃_•̃} bazel build graphd

Then, run it:

{•̃_•̃} bazel-bin/graphd/graphd -d /tmp/some-tmp-db -y
graphd> write (name="human" value="chris"
			(<- name="left leg" value="green")
			(<- name="right leg" value="blue"))
	write (name="human" value="ann"
			(<- name="left leg" value="green")
			(<- name="right leg" value="blue")
			(<- name="left arm" value="yellow")
			(<- name="right arm" value="red"))
	write (name="human" value="bob"
			(<- name="left leg" value="green")
			(<- name="right leg" value="blue")
			(<- name="left arm" value="black"))
ok (00000000400045488000000000000000 (00000000400045488000000000000001) (00000000400045488000000000000002))
ok (00000000400045488000000000000003 (00000000400045488000000000000004) (00000000400045488000000000000005) (00000000400045488000000000000006) (00000000400045488000000000000007))
ok (00000000400045488000000000000008 (00000000400045488000000000000009) (0000000040004548800000000000000a) (0000000040004548800000000000000b))

OK, now you have some data. Btw, “write(…)” is a command, lines starting with “ok (…)” are results, so only paste the write lines. Also, I mentioned that graphd is line-oriented, thats partially true - it’s also
Query oriented - this means it will wait for the closing paren.

OK, so now you have a database with data, lets run one that you can connect to with your Go code - sort of like before:

{•̃_•̃} bazel-bin/graphd/graphd -d /tmp/some-tmp-db -l /tmp/graphd.logs -p /tmp/graphd.pid 
nc[rtp-macbookpro2:~/github/graphd]
{•̃_•̃} nc localhost 8100
read()

(ctrl-D again)

OK, so now you’ve got some data to play with.
