Batch dependency scanning was added as a mechanism to support multiple compilation contexts within a single module dependency graph. The Swift compiler and the Explicitly-built modules model has long since abandoned this approach and this code has long been stale. It is time to remove it and its associated C API.

# Split swift compiler command lines into multiple lines.
|
|
#
|
|
# Reads the command line from stdin and outputs the split line to stdout.
|
|
# Example:
|
|
#
|
|
# $ swiftc -c hello.swift -### | split-cmdline
|
|
# /path-to-swift/bin/swift \
|
|
# -frontend \
|
|
# -c \
|
|
# -primary-file hello.swift \
|
|
# -target x86_64-apple-macosx10.9 \
|
|
# -enable-objc-interop \
|
|
# -color-diagnostics \
|
|
# -module-name hello \
|
|
# -o hello.o
|
|
#
|
|
# Example usage in vim:
|
|
# *) make sure that split-cmdline is in the $PATH
|
|
# *) copy-paste the swift command line the text buffer
|
|
# *) select the command line
|
|
# *) go to the command prompt (= press ':')
|
|
# :'<,'>!split-cmdline
