Reference manual / Tactic LATEX mark-up


Introduction

A LATEX mark-up for tactics is defined here by its conversion to a sequence of UCS characters.

White space and comments

Spaces, tabs and newlines are soft space: they separate tokens of the mark-up, without generating any space characters to be lexed. Braces are also soft space, affecting the interpretation of neighbouring mark-up (unless escaped with \).

The following mark-up is converted to spaces to be lexed.

LATEX command Rendering Z character
~ interword space SPACE
\, thin space SPACE
\: medium space SPACE
\; thick space SPACE
\(space) interword space SPACE
\\ newline NLCHAR
\t1 tab stop 1 SPACE
\t2 tab stop 2 SPACE
\t3 tab stop 3 SPACE
\t4 tab stop 4 SPACE
\t5 tab stop 5 SPACE
\t6 tab stop 6 SPACE
\t7 tab stop 7 SPACE
\t8 tab stop 8 SPACE
\t9 tab stop 9 SPACE
\also small vertical space NLCHAR
\znewpage new page NLCHAR

A % character in the mark-up introduces a comment: all text from that % to the end of the line, and any following spaces and tabs at the beginning of the next line, are ignored.

Mark-up directives

Each LATEXcommand needs to have a mark-up directive to define its conversion to a sequence of Z characters. The conversions defined by these mark-up directives should be consistent with the rendering produced by the LATEX typesetting tool.

The conversion of a name to a specific UCS character is defined by a mark-up directive like the following.

%%Topchar \lor U+2228

If a name is to be converted to more than one character, a directive like the following is used.

%%Topword \strapp {+}{+}

The conversions of all such names include a SPACE character before and after them.

Most tactic keywords are ASCII and are marked-up as themselves. Those that are not are marked-up using names defined by the mark-up directives given below.

Symbol characters

Z character troff mark-up
\lor %%Topchar \lor U+2228
||lel %%Topword \parlel {|{|}}
++ %%Topword \strapp {+{+}}

The @ character is marked up as '\endpat' when it marks the end of a pattern, but as '\spot' otherwise.
