# build and lib search property - aggressive build, search and cache examples
# altering these defaults might require a rebuild after changing some underlying files.
#

# ############################
# build core files in parallel
# ############################

# the vMicro parallel build setting can be off yet this property will enable parallel build of cores
# the default is false
#
builder.core.parallel_build=true


# ################################
# compile of temp\project_name.cpp
# ################################

# prevent ino code > temp/project_name.cpp from being compiled unless it, a dependency or board options have changed
# the default is false. the Arduino ide always rebuilds the file.
#
vm.build.sketch.cpp-use-build-cache=true


## ####################
## search for libraries
## ####################

# only search for 'libs in libs' in each library root (or library \src folder for vs libs)
# the default is 'all', which matches the functionality of the current arduino ide.
# switch off looking for 'libraries in libraries' by setting this property to 'none' (recommended !!)
#
# vm.preproc.lib-search.lib-in-lib=all
vm.preproc.lib-search.lib-in-lib=top-level
# vm.preproc.lib-search.lib-in-lib=none


# deep search over project source?
# the default is all which matches the arduino ide
# if all #includes are in .ino code then use 'ino-code-only'
#
# vm.preproc.lib-search.lib-in-sketch=all
# vm.preproc.lib-search.lib-in-sketch=root
vm.preproc.lib-search.lib-in-sketch=root-and-src
# vm.preproc.lib-search.lib-in-sketch=ino-code-only


# search the temp/project_name.cpp only if it has changed (or a dependency or board option has changed)
#  the Arduino ide always rescans the project_name.cpp for libraries,
#  this property defaults to false to match the current Arduino ide
#
vm.preproc.sketch.cpp-datetime-use-cache=true


# deep search uses file of original temp/projet_name.cpp, instead of the one in the build folder that is always recreated. this voids the project_name.cpp from being deep searched always, regardless of normal cache determination.
# the default is false, less efficient but matches the current Arduino ide.
#
vm.preproc.lib-search.ino-cache=true


# ####################
# prototype generation
# ####################

# use previous gcc results, if available and the sketch ino code has not changed
# default is true, the most efficient setting. 
# do not switch off without good reason.
