URL: https://github.com/gflags/gflags
Version: 2.1.2
License: New BSD
License File: LICENSE
Description:
The gflags package contains a library that implements commandline
flags processing. As such it's a replacement for getopt(). It has
increased flexibility, including built-in support for C++ types like
string, and the ability to define flags in the source file in which
they're used.
Local Modifications: None
How to update platform configuration files:
The gen/ directory contains pre-generated configuration header files.
Historically, all operating systems and architectures have generated
similar configurations except for Windows. This is why there's only
posix and win directories below gen/.
When rolling gflags to a newer version, it's a good idea to check if
new configuration files needs to be generated as well.
Do this by running cmake in the newly checked out version of
gflags. Then diff the generated files with the ones below gen/.
If you notice a diff, update the files with the updated ones.
If you suspect platform dependend changes other than Windows, you'll
have to checkout gflags on the other platforms as well and run
cmake there too.

//
// 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

// 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 GFLAGS_DLL_DECL 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.

//
// 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 \
'/home/build/eng/bash/bash_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.

// 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 GFLAGS_DLL_DECL 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

//
// 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 \
'/home/build/eng/bash/bash_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.
