This script in combination with <(...) can be used to speed up creating reproductions from command lines that use '@' files to define their inputs. An example use case: Consider a swiftc command line that uses the @ symbol. swiftc @/foo/bar/baz.txt When this is run, the @ command is expanded into a filelist in a temporary file. This doesn't work with -### since -### outputs the command line with a temporary file for the filelist, but uses a path to a temporary file that doesn't exist, e.g.: swift -frontend -filelist /tmp/tmp.filelist ... To run this command, you use the at-to-filelist command as follows: swift -frontend -filelist <(at-to-filelist /foo/bar/baz.txt)

# Transform an @ file into a file list.

|
# The intended use case is given an @ path passed to swift, use this script and
|
|
# bash to automagically expand the @ path by transforming:
|
|
#
|
|
# @/foo/bar/baz.txt
|
|
#
|
|
# =>
|
|
#
|
|
# <(at-to-filelist /foo/bar/baz.txt)
|
|
#
|
|
# For those unaware, <(...) causes bash to output the subshell's output into a
|
|
# file and then replace <(...) with the path to that temporary file.

|
# Example:
|
|
#
|
|
# Consider a swiftc command line that uses the @ symbol.
|
|
#
|
|
# swiftc @/foo/bar/baz.txt
|
|
#
|
|
# When this is run, the @ command is expanded into a filelist in a temporary
|
|
# file. This doesn't work with -### since -### outputs the command line with a
|
|
# temporary file for the filelist, but uses a path to a temporary file that
|
|
# doesn't exist, e.g.:
