+
+It's the IPL season and I thought why not keep the track of the score of the
+matches that are in progress. I have two tests tomorrow and I don't want to be
+wasting time looking at the scores every now and then; instead let's spend some
+MORE time looking into a utility that I haven't used before and test and play
+around with it. I don't even like cricket that much.
+
+The utility I am talking about here is `jq`. `jq` is a command-line JSON
+parser. You can think of it like awk that is tailord to work with JSON.
+Following the UNIX philosophy, `jq` can take it's input from the standard input
+or from a file.  That means we can pipe it's output to other programs or pipe
+in from other programs into it. `jq` has a very straight forward man page.  It
+has a mini language of it's own which is quite intuitive.
+
+The command below fetches the information using cricbuzz. Turns out they have
+an undocumented api that is publicly usable. We get the score of the batting
+side and also the status of the match. ` tr -d \" | tr \n ' '` gets rid of
+double quotes and converts the newlines into spaces.
+
+
+{{< highlight bash >}}
+#!/usr/bin/bash
+$ curl -s https://www.cricbuzz.com/match-api/livematches.json\
+    | jq '.matches."22455"|.score.batting.score,.status'\
+    | tr -d \" | tr '\n' ' '
+
+
+{{< /highlight >}}
+
+**Output**: 
+`"145/5 (18.0 Ovs) Delhi Capitals need 5 runs in 12 balls"`
+
+
+The script below sends a notification with the current score, run rate, and
+balls of the previous overs for the match id `22454`.
+
+{{< highlight bash >}}
+
+#!/usr/bin/bash
+notify-send "$(curl -s https://www.cricbuzz.com/match-api/livematches.json\
+    | jq '.matches."22454".score |.batting.score, .crr, .prev_overs'\
+    | tr \" " ")"
+
+{{< /highlight >}}
+
+I can then place them in `~/.config/i3blocks` and configure
+[i3blocks](https://www.github.com/vivien/i3blocks) to run the script every
+10-15 seconds.
+
+    [match]
+    command=match_score
+    interval=10
