4.1 Build Directory
A build directory contains Grasshopper executables generated by the builders
during build or rebuild commands.
A new build directory is created every time Grasshopper executables are built.
The build directory is named “grasshopper_<YYYY>-<MM>-<DD>_<HH>-<MM>-<SS>.build”,
based on the current date and time.
The build directory contains all of the executables produced by the builder. The
executables are named “<BASE>-<FORMAT>-<ARCH>.<EXT>”. The BASE refers to the type
of core Grasshopper executable; fully-featured executables are called
“Grasshopper”, while executables stripped of the rule engine are called “Cricket”.
The FORMAT refers to the type of executable and may be DLL or ICE-DLL. The ARCH
refers to the architecture of the executable and may be 32 (x86) or 64 (x64). The
EXT is the file-appropriate extension.
The build directory also contains metadata files required for some formats.
Grasshopper executables of the ICE DLL format will have an associated .META.xml
file in the build directory.
The build directory will include a build.xml file containing configuration data for
the built executables.
