// This is the file that should be included by any file which declares
// or defines a command line flag or wants to parse command line flags
// or print a program usage message (which will include information about
// flags). Executive summary, in the form of an example foo.cc file:
//
// #include "foo.h" // foo.h has a line "DECLARE_int32(start);"
// #include "validators.h" // hypothetical file defining ValidateIsFile()
//
// DEFINE_int32(end, 1000, "The last record to read");
//
// DEFINE_string(filename, "my_file.txt", "The file to read");
// // Crash if the specified file does not exist.
// static bool dummy = RegisterFlagValidator(&FLAGS_filename,
// &ValidateIsFile);
//
// DECLARE_bool(verbose); // some other file has a DEFINE_bool(verbose, ...)
//
// void MyFunc() {
// if (FLAGS_verbose) printf("Records %d-%d\n", FLAGS_start, FLAGS_end);
// }
//
// Then, at the command-line:
// ./foo --noverbose --start=5 --end=100
//
// For more details, see
// doc/gflags.html
//
// --- A note about thread-safety:
//
// We describe many functions in this routine as being thread-hostile,
// thread-compatible, or thread-safe. Here are the meanings we use:
//
// thread-safe: it is safe for multiple threads to call this routine
// (or, when referring to a class, methods of this class)
// concurrently.
// thread-hostile: it is not safe for multiple threads to call this
// routine (or methods of this class) concurrently. In gflags,
// most thread-hostile routines are intended to be called early in,
// or even before, main() -- that is, before threads are spawned.
// thread-compatible: it is safe for multiple threads to read from
// this variable (when applied to variables), or to call const
// methods of this class (when applied to classes), as long as no
// other thread is writing to the variable or calling non-const
// methods of this class.

// To actually define a flag in a file, use DEFINE_bool,
// DEFINE_string, etc. at the bottom of this file. You may also find
// it useful to register a validator with the flag. This ensures that
// when the flag is parsed from the commandline, or is later set via
// SetCommandLineOption, we call the validation function. It is _not_
// called when you assign the value to the flag directly using the = operator.
//
// The validation function should return true if the flag value is valid, and
// false otherwise. If the function returns false for the new setting of the
// flag, the flag will retain its current value. If it returns false for the
// default value, ParseCommandLineFlags() will die.
//
// This function is safe to call at global construct time (as in the
// example below).
//
// Example use:
// static bool ValidatePort(const char* flagname, int32 value) {
// if (value > 0 && value < 32768) // value is ok
// return true;
// printf("Invalid value for --%s: %d\n", flagname, (int)value);
// return false;
// }
// DEFINE_int32(port, 0, "What port to listen on");
// static bool dummy = RegisterFlagValidator(&FLAGS_port, &ValidatePort);
// Returns true if successfully registered, false if not (because the
// first argument doesn't point to a command-line flag, or because a
// validator is already registered for this flag).

// access flags are quiescent. Referencing flags after this is called
// will have unexpected consequences. This is not safe to run when
// multiple threads might be running: the function is thread-hostile.
extern void ShutDownCommandLineFlags();
// --------------------------------------------------------------------
// Now come the command line flag declaration/definition macros that
// will actually be used. They're kind of hairy. A major reason
// for this is initialization: we want people to be able to access
// variables in global constructors and have that not crash, even if
// their global constructor runs before the global constructor here.
// (Obviously, we can't guarantee the flags will have the correct
// default value in that case, but at least accessing them is safe.)
// The only way to do that is have flags point to a static buffer.
// So we make one, using a union to ensure proper alignment, and
// then use placement-new to actually set up the flag with the
// correct default value. In the same vein, we have to worry about
// flag access in global destructors, so FlagRegisterer has to be
// careful never to destroy the flag-values it constructs.
//
// Note that when we define a flag variable FLAGS_<name>, we also
// preemptively define a junk variable, FLAGS_no<name>. This is to
// cause a link-time error if someone tries to define 2 flags with
// names like "logging" and "nologging". We do this because a bool
// flag FLAG can be set from the command line to true with a "-FLAG"
// argument, and to false with a "-noFLAG" argument, and so this can
// potentially avert confusion.
//
// We also put flags into their own namespace. It is purposefully
// named in an opaque way that people should have trouble typing
// directly. The idea is that DEFINE puts the flag in the weird
// namespace, and DECLARE imports the flag from there into the current
// namespace. The net result is to force people to use DECLARE to get
// access to a flag, rather than saying "extern bool FLAGS_whatever;"
// or some such instead. We want this so we can put extra
// functionality (like sanity-checking) in DECLARE if we want, and
// make sure it is picked up everywhere.
//
// We also put the type of the variable in the namespace, so that
// people can't DECLARE_int32 something that they DEFINE_bool'd
// elsewhere.

// Each command-line flag has two variables associated with it: one

// Implement helpful bash-style command line flag completions
//
// ** Functional API:
// HandleCommandLineCompletions() should be called early during
// program startup, but after command line flag code has been
// initialized, such as the beginning of HandleCommandLineHelpFlags().
// It checks the value of the flag --tab_completion_word. If this
// flag is empty, nothing happens here. If it contains a string,
// however, then HandleCommandLineCompletions() will hijack the
// process, attempting to identify the intention behind this
// completion. Regardless of the outcome of this deduction, the
// process will be terminated, similar to --helpshort flag
// handling.
//
// ** Overview of Bash completions:
// Bash can be told to programatically determine completions for the
// current 'cursor word'. It does this by (in this case) invoking a
// command with some additional arguments identifying the command
// being executed, the word being completed, and the previous word
// (if any). Bash then expects a sequence of output lines to be
// printed to stdout. If these lines all contain a common prefix
// longer than the cursor word, bash will replace the cursor word
// with that common prefix, and display nothing. If there isn't such
// a common prefix, bash will display the lines in pages using 'more'.
//
// ** Strategy taken for command line completions:
// If we can deduce either the exact flag intended, or a common flag
// prefix, we'll output exactly that. Otherwise, if information
// must be displayed to the user, we'll take the opportunity to add
// some helpful information beyond just the flag name (specifically,
// we'll include the default flag value and as much of the flag's
// description as can fit on a single terminal line width, as specified
// by the flag --tab_completion_columns). Furthermore, we'll try to
// make bash order the output such that the most useful or relevent
// flags are the most likely to be shown at the top.
//
// ** Additional features:
// To assist in finding that one really useful flag, substring matching
// was implemented. Before pressing a <TAB> to get completion for the
// current word, you can append one or more '?' to the flag to do
// substring matching. Here's the semantics:
// --foo<TAB> Show me all flags with names prefixed by 'foo'
// --foo?<TAB> Show me all flags with 'foo' somewhere in the name
// --foo??<TAB> Same as prior case, but also search in module
// definition path for 'foo'
// --foo???<TAB> Same as prior case, but also search in flag
// descriptions for 'foo'
// Finally, we'll trim the output to a relatively small number of
// flags to keep bash quiet about the verbosity of output. If one
// really wanted to see all possible matches, appending a '+' to the
// search word will force the exhaustive list of matches to be printed.
//
// ** How to have bash accept completions from a binary:
// Bash requires that it be informed about each command that programmatic
// completion should be enabled for. Example addition to a .bashrc
// file would be (your path to gflags_completions.sh file may differ):
/*
$ complete -o bashdefault -o default -o nospace -C \
'/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \
time env binary_name another_binary [...]
*/
// This would allow the following to work:
// $ /path/to/binary_name --vmodule<TAB>
// Or:
// $ ./bin/path/another_binary --gfs_u<TAB>
// (etc)
//
// Sadly, it appears that bash gives no easy way to force this behavior for
// all commands. That's where the "time" in the above example comes in.
// If you haven't specifically added a command to the list of completion
// supported commands, you can still get completions by prefixing the
// entire command with "env".
// $ env /some/brand/new/binary --vmod<TAB>
// Assuming that "binary" is a newly compiled binary, this should still
// produce the expected completion output.
