Makefile

#
# Key targets in this makefile:
#
# make build
#   Build the runtime library and plugin
# make test
#   Build everything, run both plugin and library tests:
#   Plugin test verifies that plugin output matches the "Reference" files
#      exactly
#   Library test exercises most features of the generated code
# make regenerate
#   Recompile all the necessary protos
#   (requires protoc in path)
#
# Caution: 'test' does not 'regenerate', so if you've made changes to the code
# generation, you'll need to do more than just 'test':
#    1. 'make build' to build the plugin
#    2. 'make regenerate' to rebuild the Swift code from protos using the new
#       plugin
#    3. 'make build' again to recompile everything with the regenerated protos
#    4. 'make test' to run the test suites
#

# Test the plugin by itself:

#   * Compare output with reference output in Reference directory
#   * If generated output and reference output don't match exactly, fail.

# In that case, you'll need to do the following before committing:

# Collect a list of words that appear in the SwiftProtobuf library
# source.  These are words that may cause problems for generated code.
#
# The logic here builds a word list as follows:
#  = Look at every Swift source file in the library
#  = Take every line with the word 'public', 'func', or 'var'
#  = Remove any comments from the line.
#  = Break each such line into words (stripping all punctuation)
#  = Remove words that differ only in case
#  = Remove anything that will cause proto parsing issues (things named "reserved")
#
# Selecting lines with 'public', 'func' or 'var' ensures we get every
# public protocol, struct, enum, or class name, as well as every
# method or property defined in a public protocol, struct, or class.
# It also gives us a large collection of Swift names.
