Question

is there an easy way to accomplish ant expandproperties functionality in Makefiles?, an example follows:

Given the three files:

File main.properties

principal.name=John

File 1.properties

name=${principal.name}

File 2.xml

<properties name="${principal.name}"/>

I’m pursuing to replace all appareances of principal.name in files 1.properties and 2.xml with John, i should use GNU tools for i intend to incorporate it in a Makefile

Answer 1

Yep, this is doable. I’m doing it here by using awk to construct a sed script which does the substitution:

cat main.properties | awk -F= '{print "s/\\${" $1 "}/" $2 "/g"}' | sed -f - 1.properties
