#
# Simple build.conf test file
#
# you can have as many actions as you'd like, the one that's run by default is
# called "default action", you need a default action.
#
# Actions are filled with a comma-seperated list of commands, like "check xxx"
# to check to see if a target needs to be rebuilt
#
default action: check congo, check congod
#
# This action will only build the server program
#
server action: check congod
#
# After that, it helps to define some targets, things that commands usually
# refer to and interact with.
#
#
# "create file" will do just what it says, create a file based on some
# information and a rule.
#
# "from files in" tells us that a list of directories follows, and the input
# list for the rule should be built from these files.
#
# "using rule" tells us which rule to use to actuall create the file
#
create file congod from files in src/congod, src/shared using rule exe
create file congo from files in src/congo, src/shared using rule exe
create files "modules/db{name}.so" from directories in src/congod/db ...
from files in "src/congod/db/{name}" using rule lib
#
# After all of that, some targets or list items may have their own additional
# dependancies, depending on the rule that built them. You can define these
# extra dependancies using "xxx requires yyy" which will force the system to
# attempt to create yyy before xxx.
#
congod requires libcongo.a
congo requires libcongo.a
#
# There are a number of variables that the rules can use, including any in the
# environment. Sometimes you want to modify these, to do that you can use "set"
# and the name of the variable, along with what to do to it.
#
# You can use '=' to set the value, destroying what was there, or '+=' to add
# the new text to the variable, this will assume that the text you provide is
# made up of space-delimited tokens, and will ensure spaces surround them when
# they are added.
#
set CXXFLAGS += "-Ilibbu++/src"
set LDFLAGS += "-Llibbu++ -lbu++"
#
# Sometimes individual targets or list items require special settings, this is
# easy since build maintians a seperate set of variables for any items that need
# special support.
#
# Currently you can only set, for an item, later you may be able to do more.
#
for congo set LDFLAGS += "-lreadline"
#
# Finally, no file is complete without some rules. Rules determine how to
# fulfill target checking based on some input data. Generally this is going to
# be creating an executable from a list of source files.
#
#
# First specify the rule name, then you can filter the input list, if desired,
# in two ways. You can use items that match a regular expression, and execute
# the rule once for the whole list collectively, or once for each element that
# made it through the filter.
#
# Within the perform, there are several things that could go there, for now,
# just command, which takes a string, you can use {} for variable substitution.
#
rule exe matches all /(.*)\.o/ perform command ...
"g++ {matches} {LDFLAGS} -o {target}"
rule cpp matches one /(.*)\.cpp/ produces {1}.o perform command ...
"g++ {CXXFLAGS} -o {target} {match}"
