These -options are the same for all symbols, although their default values -may vary. The @Code "style" option changes the printing style; its -value may be {@Code "fixed"} (fixed-width font), {@Code "varying"} -(varying-width font), or {@Code "symbol"} (varying-width font with -mathematical symbols used for some operators). Its default value -depends on the language, and may be found in the fourth column of -the table at the start of this chapter. The example in the previous -section was in @Code fixed style; we can switch styles like this: -@ID @OneRow @Code { -"@CP" -" style { varying }" -"{" -"#include <stdio.h>" -"" -"treeprint(p) /* print tree p recursively */" -"struct tnode *p;" -"{" -" if (p != NULL) {" -" treeprint(p->left);" -" printf(\"%4d %s\\n\", p->count, p->word);" -" treeprint(p->right);" -" }" -"}" -"}" -} -The result in this case will be -@ID @OneRow @CP style { varying } -{ -#include <stdio.h> - -treeprint(p) /* print tree p recursively */ -struct tnode *p; -{ - if (p != NULL) { - treeprint(p->left); - printf("%4d %s\n", p->count, p->word); - treeprint(p->right); - } -} -} -If we use @Code "style { symbol }" we get this: -@ID @OneRow @CP style { symbol } -{ -#include <stdio.h> - -treeprint(p) /* print tree p recursively */ -struct tnode *p; -{ - if (p != NULL) { - treeprint(p->left); - printf("%4d %s\n", p->count, p->word); - treeprint(p->right); - } -} -} -with mathematical symbols replacing some of the operators. -@PP -The {@Code "@CP"}, {@Code "@Eiffel"} etc. symbols have additional options -which allow a finer control over the style. Here they all are, with their -default values: -@ID @OneRow @Code { -"@CP [ or @Eiffel, @Blue, etc. ]" -" style { fixed }" -" font { Courier }" -" strings { Base }" -" identifiers { Base }" -" comments { Base }" -" keywords { Base }" -" numbers { Base }" -" operators { Base }" -" size { -1.0p }" -" line { 1.0vx }" -" tabin { 8 }" -" tabout { 8s }" -"{" -" ..." -"}" -} -We are already familiar with {@Code "style"}. After that comes -{@Code "font"}, which determines the font family to use, followed -by six options giving the particular faces within that family in which to -print strings, identifiers, comments, keywords, numbers, and -operators. {@Code "Base"} means the basic face; other commonly available -choices are {@Code "Slope"} and {@Code "Bold"}. These options may all be -set to different faces if desired. The default values shown are correct -for @Code "style { fixed }" only; the other styles have other defaults -(Section {@NumberOf cpsetup}). -@PP -The @Code "size" option is the font size to use, and @Code "line" is the -inter-line spacing. The default values specify that @Code "size" is -to be one point smaller than in the surrounding document; this was done -to compensate for Courier's relatively large appearance compared -to other fonts of the same nominal size. Again, these defaults are -different for different values of {@Code "style"}. -@PP -The @Code "tabin" and @Code "tabout" options are the subject of -Section {@NumberOf tabs}. -@End @Section |
