# This is a pretty brute-force approach. It takes several hours to run on a top-spec MacbookAir.
|
|
# It also produces some false positives, so it requires careful examination and testing of the results.
|
|
#
|
|
# Algorithm Summary:
|
|
# First we find all #defines,
|
|
# then we search for each of them in turn,
|
|
# and if we find only one instance of a #define, we print it out.
|
|
#
|
|
# Algorithm Detail:
|
|
# (1) find #defines, excluding the externals folder
|
|
# (2) extract just the constant name from the search results
|
|
# (3) trim blank lines
|
|
# (4) sort the results, mostly so I have an idea how far along the process is
|
|
# (5) for each result:
|
|
# (6) grep for the constant
|
|
# (7) use awk to to check if only one match for a given constant was found
|
|
# (8) if so, generate a sed command to remove the #define
|
|
