Consequently, the + programming of groff postprocessors is similar to the development of + device drivers. + + The prototyping for this file is done in driver.h (and error.h). +*/ + +/* Changes of the 2001 rewrite of this file. + + The interface to the outside and the handling of the global + variables was not changed, but internally many necessary changes + were performed. + + The main aim for this rewrite is to provide a first step towards + making groff fully compatible with classical troff without pain. + + Bugs fixed + - Unknown subcommands of 'D' and 'x' are now ignored like in the + classical case, but a warning is issued. This was also + implemented for the other commands. + - A warning is emitted if 'x stop' is missing. + - 'DC' and 'DE' commands didn't position to the right end after + drawing (now they do), see discussion below. + - So far, 'x stop' was ignored. Now it terminates the processing + of the current intermediate output file like the classical troff. + - The command 'c' didn't check correctly on white-space. + - The environment stack wasn't suitable for the color extensions + (replaced by a class). + - The old groff parser could only handle a prologue with the first + 3 lines having a fixed structure, while classical troff specified + the sequence of the first 3 commands without further + restrictions. Now the parser is smart about additional + white space, comments, and empty lines in the prologue. + - The old parser allowed space characters only as syntactical + separators, while classical troff had tab characters as well. + Now any sequence of tabs and/or spaces is a syntactical + separator between commands and/or arguments. + - Range checks for numbers implemented. + + New and improved features + - The color commands 'm' and 'DF' are added. + - The old color command 'Df' is now converted and delegated to 'DFg'. + - The command 'F' is implemented as 'use intended file name'. It + checks whether its argument agrees with the file name used so far, + otherwise a warning is issued. Then the new name is remembered + and used for the following error messages. + - For the positioning after drawing commands, an alternative, easier + scheme is provided, but not yet activated; it can be chosen by + undefining the preprocessor macro STUPID_DRAWING_POSITIONING. + It extends the rule of the classical troff output language in a + logical way instead of the rather strange actual positioning. + For details, see the discussion below. + - For the 'D' commands that only set the environment, the calling of + pr->send_draw() was removed because this doesn't make sense for + the 'DF' commands; the (changed) environment is sent with the + next command anyway. + - Error handling was clearly separated into warnings and fatal. + - The error behavior on additional arguments for 'D' and 'x' + commands with a fixed number of arguments was changed from being + ignored (former groff) to issue a warning and ignore (now), see + skip_line_x(). No fatal was chosen because both string and + integer arguments can occur. + - The gtroff program issues a trailing dummy integer argument for + some drawing commands with an odd number of arguments to make the + number of arguments even, e.g. the DC and Dt commands; this is + honored now. + - All D commands with a variable number of args expect an even + number of trailing integer arguments, so fatal on error was + implemented. + - Disable environment stack and the commands '{' and '}' by making + them conditional on macro USE_ENV_STACK; actually, this is + undefined by default. There isn't any known application for these + features. + + Cosmetics + - Nested 'switch' commands are avoided by using more functions. + Dangerous 'fall-through's avoided. + - Commands and functions are sorted alphabetically (where possible). + - Dynamic arrays/buffers are now implemented as container classes. + - Some functions had an ugly return structure; this has been + streamlined by using classes. + - Use standard C math functions for number handling, so getting rid + of differences to '0'. + - The macro 'IntArg' has been created for an easier transition + to guaranteed 32 bits integers ('int' is enough for GNU, while + ANSI only guarantees 'long int' to have a length of 32 bits). + - The many usages of type 'int' are differentiated by using 'Char', + 'bool', and 'IntArg' where appropriate. + - To ease the calls of the local utility functions, the parser + variables 'current_file', 'npages', and 'current_env' + (formerly env) were made global to the file (formerly they were + local to the do_file() function) + - Various comments were added. + + TODO + - Get rid of the stupid drawing positioning. + - Can the 'Dt' command be completely handled by setting environment + within do_file() instead of sending to pr? + - Integer arguments must be >= 32 bits, use conditional #define. + - Add scaling facility for classical device independence and + non-groff devices. Classical troff output had a quasi device + independence by scaling the intermediate output to the resolution + of the postprocessor device if different from the one specified + with 'x T', groff have not. So implement full quasi device + independence, including the mapping of the strange classical + devices to the postprocessor device (seems to be reasonably + easy). + - The external, global pointer variables are not optimally handled. + - The global variables 'current_filename', + 'current_source_filename', and 'current_lineno' are only used for + error reporting. So implement a static class 'Error' + ('::' calls). + - The global 'device' is the name used during the formatting + process; there should be a new variable for the device name used + during the postprocessing. + - Implement the B-spline drawing 'D~' for all graphical devices. + - Make 'environment' a class with an overflow check for its members + and a delete method to get rid of delete_current_env(). + - Implement the 'EnvStack' to use 'new' instead of 'malloc'. + - The class definitions of this document could go into a new file. + - The comments in this section should go to a 'Changelog' or some + 'README' file in this directory. +*/ + +/* + Discussion of the positioning by drawing commands + + There was some confusion about the positioning of the graphical + pointer at the printout after having executed a 'D' command. + The classical troff manual of Ossanna & Kernighan specified, + + 'The position after a graphical object has been drawn is + at its end; for circles and ellipses, the "end" is at the + right side.' + + From this, it follows that + - all open figures (args, splines, and lines) should position at their + final point. + - all circles and ellipses should position at their right-most point + (as if 2 halves had been drawn). + - all closed figures apart from circles and ellipses shouldn't change + the position because they return to their origin. + - all setting commands should not change position because they do not + draw any graphical object. + + In the case of the open figures, this means that the horizontal + displacement is the sum of all odd arguments and the vertical offset + the sum of all even arguments, called the alternate arguments sum + displacement in the following. + + Unfortunately, groff did not implement this simple rule. The former + documentation in groff_out(5) differed from the source code, and + neither of them is compatible with the classical rule. + + The former groff_out(5) specified to use the alternative arguments + sum displacement for calculating the drawing positioning of + non-classical commands, including the 'Dt' command (setting-only) + and closed polygons. Applying this to the new groff color commands + will lead to disaster. For their arguments can take large values (> + 65000). On low resolution devices, the displacement of such large + values will corrupt the display or kill the printer. So the + nonsense specification has come to a natural end anyway. + + The groff source code, however, had no positioning for the + setting-only commands (esp. 'Dt'), the right-end positioning for + outlined circles and ellipses, and the alternative argument sum + displacement for all other commands (including filled circles and + ellipses). + + The reason why no one seems to have suffered from this mayhem so + far is that the graphical objects are usually generated by + preprocessors like pic that do not depend on the automatic + positioning. When using the low level '\D' escape sequences or 'D' + output commands, the strange positionings can be circumvented by + absolute positionings or by tricks like '\Z'. + + So doing an exorcism on the strange, incompatible displacements might + not harm any existing documents, but will make the usage of the + graphical escape sequences and commands natural. + + That's why the rewrite of this file returned to the reasonable, + classical specification with its clear end-of-drawing rule that is + suitable for all cases. But a macro STUPID_DRAWING_POSITIONING is + provided for testing the funny former behavior. + + The new rule implies the following behavior. + - Setting commands ('Dt', 'Df', 'DF') and polygons ('Dp' and 'DP') + do not change position now. + - Filled circles and ellipses ('DC' and 'DE') position at their + most right point (outlined ones 'Dc' and 'De' did this anyway). + - As before, all open graphical objects position to their final + drawing point (alternate sum of the command arguments). + +*/ + +#ifndef STUPID_DRAWING_POSITIONING +// uncomment next line if all non-classical D commands shall position +// to the strange alternate sum of args displacement +#define STUPID_DRAWING_POSITIONING +#endif + +// Decide whether the commands '{' and '}' for different environments +// should be used. +#undef USE_ENV_STACK + +#include "driver.h" +#include "device.h" + +#include <stdlib.h> +#include <errno.h> +#include <ctype.h> +#include <math.h> + + +/********************************************************************** + local types + **********************************************************************/ + +// integer type used in the fields of struct environment (see printer.h) +typedef int EnvInt;
