Detailed Description

This is intended to be the base class for most general-purpose utility programs in the PANDATOOL tree.

It automatically handles things like command-line arguments in a portable way.

Member Function Documentation

◆ get_exec_command()

string ProgramBase::get_exec_command ( ) const

Returns the command that invoked this program, as a shell-friendly string, suitable for pasting into the comments of output files.

Definition at line 455 of file programBase.cxx.

References Filename::get_basename_wo_extension().

◆ parse_command_line()

void ProgramBase::parse_command_line ( int  argc,
char **  argv 
)
virtual

Dispatches on each of the options on the command line, and passes the remaining parameters to handle_args().

If an error on the command line is detected, will automatically call show_usage() and exit(1).

Definition at line 274 of file programBase.cxx.

References Filename::from_os_specific(), and preprocess_argv().

◆ show_description()

void ProgramBase::show_description ( )

Writes the program description to stderr.

Definition at line 129 of file programBase.cxx.

◆ show_options()

void ProgramBase::show_options ( )

Describes each of the available options to stderr.

Definition at line 152 of file programBase.cxx.

◆ show_text() [1/2]

void ProgramBase::show_text ( const std::string &  text)
inline

Formats the indicated text to stderr with the known _terminal_width.

Definition at line 18 of file programBase.I.

◆ show_text() [2/2]

void ProgramBase::show_text ( const std::string &  prefix,
int  indent_width,
std::string  text 
)

Formats the indicated text and its prefix for output to stderr with the known _terminal_width.

Definition at line 174 of file programBase.cxx.

◆ show_usage()

void ProgramBase::show_usage ( )

Writes the usage line(s) to stderr.

Definition at line 137 of file programBase.cxx.

◆ write_man_page()

void ProgramBase::write_man_page ( std::ostream &  out)

Generates a man page in nroff syntax based on the description and options.

This is useful when creating a man page for this utility.

Definition at line 189 of file programBase.cxx.
