None of these sources are referenced, either directly or indirectly,
in any CMakeLists.txt file.
NOTE: All of legacy/ is unused, but we're keeping it around.
Process for this commit: (in bash)
**NOTE: THIS MUST BE DONE ON A CASE-SENSITIVE FILESYSTEM**. There are a
few instances of differing-in-case-only (hogmaker vs HogMaker, etc) that
will catch you out otherwise.
```
# *** 1: Find all directly-referenced c/cpp files in CMakeLists.txt
find . -name CMakeLists.txt -exec cat {} \+ |
# Then, convert spaces and tabs to newlines for easy tokenizing
tr -s ' \t' '\n' |
# Filter to just tokens descripting c/cpp filenames (case insensitive)
grep -iE '\.c(pp)?' |
# Massage each filename to remove CMake-specific chars
sed 's/[")]//g' |
# Remove a URL that happens to match the pattern so far
grep -v https: |
# Remove files that start with # (and are thus comments, not refs)
grep -Ev '^#' |
# *** 2: In the output so far there is a curious entry ${SCRIPT}.cpp
# Turns out, the makefiles generate some further filenames from script
# names. So, delete the ${SCRIPT}.cpp filename...
grep -v '${SCRIPT}.cpp' |
# .. and add in the cpps.
(
# We use a bash subshell to let us "concatenate" to the pipe. This
# writes stdin back to stdout, and then starts a *new command* to
# generate more to stdout.
cat -;
# All the generated script cpp references live in scripts/
cat scripts/CMakeLists.txt |
# Squash the makefile onto one line for regex ease
tr '\n' ' ' |
# Extract the script names
sed -E 's/.*set\(SCRIPTS([^)]+)\).*/\1/' |
# Convert spaces and tabs to newlines for easy tokenizing
tr -s ' \t' '\n' |
# Remove blank lines
grep -v '^$' |
# Add cpp extension to each token
while read TOKEN; do
echo ${TOKEN}.cpp;
done
) |
# *** 3: Being referenced by CMakeFiles.txt isn't the only way a src
# file can be used - it could also be potentially #include'ed. Let's
# find those, with another subshell concatenation:
(
cat -;
# Look in ALL source files. We could actually probably limit the
# search here to just src files listed so far in stdin + *.h, but
# that'd require a bunch of redirections and this bash pipeline is
# already ridiculous enough. (Case!)
find . -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" |
# Pull out the #include directives from them
xargs grep --no-filename '#include' |
# Look for any include of a .c or .cpp file (Case!)
grep -iE '\.c(pp)?' |
# Squash multiple spaces and tabs into one single space
tr -s ' \t' ' ' |
# Split on spaces, take the second field
cut -d ' ' -f 2 |
# Delete off quotes and angle brackets to get the included filename
tr -d '"<>'
) |
# *** 4: Protect all files under legacy/, per @Lgt2x's request
(
cat -;
find legacy -iname "*.cpp" -or -iname "*.c"
) |
# *** 5: Reduce all entries to their basename
while read FILENAME; do
basename $FILENAME;
done |
# *** 6: FINALLY, sort and dedupe the output into a file.
sort | uniq > used_srcs
# Now that we know all the used source files, we need to find all of
# the source files in the repo, and delete them if they do not appear
# in the used_srcs list.
for SRC in $(find . -iname "*.cpp" -or -iname "*.c"); do
# find outputs the relative path, we want to operate on just filename
basename $SRC |
# grep to see if the basename occurs in the used_srcs list.
# -q means be quiet, do not print the match (so this doesn't spam)
# -x means match the entire line (so macfile.cpp doesn't sneak thru
# via cfile.cpp)
# -F means treat the lines patterns as fixed (not regexp)
# -f means load patterns from the given file
grep -qxFf used_srcs ||
# If the grep command *fails*, then the file is not in the list.
# Bash performs logic short-circuiting, so we can use logical-OR
git rm $SRC;
done
```
Test Plan:
On all three of `[win, mac, linux]`:
```
cmake --preset <platform>
cmake --build --preset <platform> --config Debug
cmake --build --preset <platform> --config Release
```
