Parse command line arguments from response files.
This file is not shared with other compilers which use the DMD front-end.
alias responseExpand = responseExpandFrom!(lookupInEnvironment).responseExpandFrom;
nothrow const(char)* responseExpandFrom(alias lookup)(ref Strings args);
Expand any response files in command line. Response files are arguments that look like: @NAME The names are resolved by calling the 'lookup' function passed as a template parameter. That function is expected to first check the environment and then the file system. Arguments are separated by spaces, tabs, or newlines. These can be imbedded within arguments by enclosing the argument in "". Backslashes can be used to escape a ". A line comment can be started with #. Recursively expands nested response files.
To use, put the arguments in a Strings object and call this on it.
Digital Mars's MAKE program can be notified that a program can accept long command lines via environment variables by preceding the rule line for the program with a *.
lookup alias to a function that is called to look up response file arguments in the environment. It is expected to accept a null- terminated string and return a mutable char[] that ends with a null-terminator or null if the response file could not be resolved.
Strings args array containing arguments as null-terminated strings
null on success, or the first response file that could not be found
pure nothrow bool insertArgumentsFromResponse(char[] buffer, ref Strings args, ref size_t argIndex);
Take the contents of a response-file 'buffer', parse it and put the resulting arguments in 'args' at 'argIndex'. 'argIndex' will be updated to point just after the inserted arguments. The logic of this should match that in setargv()
char[] buffer mutable string containing the response file
Strings args list of arguments
size_t argIndex position in 'args' where response arguments are inserted
true if another response argument was found
