4 groff_ms \- groff ms macros
15 This manual page describes the GNU version of the ms macros,
16 which is part of the groff document formatting system.
17 The groff ms macros are intended to be compatible with the 4.3
19 Unix ms macros subject to the following limitations:
21 the internals of groff ms are not similar to the internals of Unix ms
22 and so documents that depend upon implementation details of Unix ms
23 may well not work with groff ms;
25 there is no support for typewriter-like devices;
27 Berkeley localisms, in particular the
31 macros, are not implemented;
34 does not provide cut marks;
36 multiple line spacing is not allowed
37 (use a larger vertical spacing instead);
39 groff ms does not work in compatibility mode (eg with the
43 the error-handling policy of groff ms
44 is to detect and report errors,
45 rather than silently to ignore them.
47 The groff ms macros make use of many features of GNU troff
48 and therefore cannot be used with any other troff.
50 Bell Labs localisms are not implemented in either the
52 ms macros or in the groff ms macros.
54 Some Unix ms documentation says that the
58 number registers can be used to control the column width and
59 gutter width respectively.
61 These number registers are not used in groff ms.
63 Macros that cause a reset set the indent.
64 Macros that change the indent do not increment or decrement
65 the indent, but rather set it absolutely.
66 This can cause problems for documents that define
67 additional macros of their own.
68 The solution is to use not the
70 request but instead the
78 is set to 1 by the groff ms macros,
79 but is not used by the Unix ms macros.
80 It is intended that documents that need to determine whether
81 they are being formatted with Unix ms or groff ms make use of this
84 Footnotes are implemented so that they can safely be used within
86 Automatically numbered footnotes within floating keeps are
88 It is safe to have another
94 it is required only that each
96 occur after the corresponding
98 and that the occurrences of
100 are in the same order as the corresponding occurrences of
107 can be used to begin and end a superscript.
109 Some Unix V10 ms features are implemented.
115 macros can have an optional third argument which will be printed
116 in the current font before the first argument.
121 that changes to a constant-width font.
123 The following strings can be redefined to adapt the groff ms macros
124 to languages other than English:
127 .ta \w'REFERENCES'u+2n
130 REFERENCES References
132 TOC Table of Contents
147 The font family is reset from the string
149 at initialization if this string is undefined it is set to the current
151 The point size, vertical spacing, and inter-paragraph spacing for footnotes
152 are taken from the number registers
157 at initialization these are set to
162 respectively; however, if any of these registers has been defined
163 before initialization, it will not be set.
165 Right-aligned displays are available with
170 The following conventions are used for names of macros, strings and
172 External names available to documents that use the groff ms
173 macros contain only uppercase letters and digits.
174 Internally the macros are divided into modules.
175 Names used only within one module are of the form
176 .IB module * name\fR.
177 Names used outside the module in which they are defined are of the form
178 .IB module @ name\fR.
179 Names associated with a particular environment are of the form
180 .IB environment : name;
181 these are used only within the
186 does not have a module prefix.
187 Constructed names used to implement arrays are of the form
188 .IB array ! index\fR.
189 Thus the groff ms macros reserve the following names:
200 names containing only uppercase letters and digits.
