Use envsetup.sh at your own source tree

envsetup.sh that came with AOSP provide lots handy command when browse android source tree.

By default, it will require envsetup.sh reside at $TOP/build, so we could modify it to remove this requirement :


neomacbookair:home neo$ diff envsetup.sh nenvsetup.sh 
18c18
<     for i in `cat $T/build/envsetup.sh | sed -n "/^function /s/function \([a-z_]*\).*/\1/p" | sort`; do
---
>     for i in `cat ~/Dropbox/home/nenvsetup.sh | sed -n "/^function /s/function \([a-z_]*\).*/\1/p" | sort`; do
555,556c555,556
<     local TOPFILE=build/core/envsetup.mk
<     if [ -n "$TOP" -a -f "$TOP/$TOPFILE" ] ; then
---
>     local TOPFILE=~/Dropbox/home/nenvsetup.sh
>     if [ -n "$TOP" -a -f "$TOPFILE" ] ; then


I rename envsetup.sh into nenvsetup.sh, and placed in ~/Dropbox/home folder. In my source tree, I could simply type :


neomacbookair:mp007 neo$ export TOP=`pwd`
neomacbookair:mp007 neo$ . ~/Dropbox/home/nenvsetup.sh 

Then you could use it's utility to travel your source tree :

neomacbookair:mp007 neo$ godir Config.java

   [2] ./src/com/wong/mprj/mp007

neomacbookair:mp007 neo$ ls -l Config.java 
-rw-r--r--  1 neo  staff  906  8 27 14:13 Config.java

neomacbookair:mp007 neo$ godir mprj-jni.cpp
   [1] ./jni/libmprj
   [2] ./jni/libtest

Select one: 2
neomacbookair:libtest neo$ ls -l mprj-jni.cpp 
-rw-r--r--  1 neo  staff  1808  8 18 23:10 mprj-jni.cpp


neomacbookair:libtest neo$ croot
neomacbookair:mp007 neo$ 

Of course you may use cgrep, jgrep too, for those m, mm utility it may require more hack before you can use, but I am fine with croot, godir, that's enough for me.
