However, most people would +not want to have a different style for every C text in their document; +they want to define the style once at the start, and have all their +C texts come out in that style without laboriously setting options +on every @Code "@CP" symbol. This is done by copying the setup file +and changing it. +@PP +For general information about how to make your own setup file, consult +Section {@NumberOf setup}. The options that determine the default +values are in the @Code "@CPSetup" @Code "@Use" clause near the end of +cprint. @Index @Code "@CPSetup" +the @Code "cpsetup." setup file: +@ID @Code @Tab + vmargin { 0.5vx } + @Fmta { @Col A ! @Col B ! @Col C} + @Fmtb { @Col { " #" A } ! @Col { "{" B } ! @Col "}" } +{ +@Rowa A { "@Use { @CPSetup" } +@Rowb A { "style" } B { fixed } + +@Rowa +@Rowb A { "fixedfont" } B { Courier } +@Rowb A { "fixedstrings" } B { Base } +@Rowb A { "fixedidentifiers" } B { Base } +@Rowb A { "fixedcomments" } B { Base } +@Rowb A { "fixedkeywords" } B { Base } +@Rowb A { "fixednumbers" } B { Base } +@Rowb A { "fixedoperators" } B { Base } +@Rowb A { "fixedsize" } B { -1.0p } +@Rowb A { "fixedline" } B { 1.0vx } +@Rowb A { "fixedtabin" } B { 8 } +@Rowb A { "fixedtabout" } B { 8s } + +@Rowa +@Rowb A { "varyingfont" } B { } +@Rowb A { "varyingstrings" } B { Slope } +@Rowb A { "varyingidentifiers" } B { Slope } +@Rowb A { "varyingcomments" } B { Base } +@Rowb A { "varyingkeywords" } B { Bold } +@Rowb A { "varyingnumbers" } B { Base } +@Rowb A { "varyingoperators" } B { Base } +@Rowb A { "varyingsize" } B { 1.0f } +@Rowb A { "varyingline" } B { 1.0vx } +@Rowb A { "varyingtabin" } B { 8 } +@Rowb A { "varyingtabout" } B { 3f } + +@Rowa +@Rowb A { "symbolfont" } B { } +@Rowb A { "symbolstrings" } B { Slope } +@Rowb A { "symbolidentifiers" } B { Slope } +@Rowb A { "symbolcomments" } B { Base } +@Rowb A { "symbolkeywords" } B { Bold } +@Rowb A { "symbolnumbers" } B { Base } +@Rowb A { "symboloperators" } B { Base } +@Rowb A { "symbolsize" } B { 1.0f } +@Rowb A { "symbolline" } B { 1.0vx } +@Rowb A { "symboltabin" } B { 8 } +@Rowb A { "symboltabout" } B { 3f } + +@Rowa A { "}" } +} +These show the default font families, font faces, font sizes, line +spacings, and tab settings in force for the three styles, and also that +the default style is {@Code "fixed"}. Notice that the font family name +for @Code "fixed" style is {@Code "Courier"}, but for the other styles is +empty. This causes the @Code "fixed" style to always switch to Courier, +and the other styles to use the same font family as in the surrounding +document. +@PP +To change a default value, delete the preceding @Code "#" and change the +part between braces. For example, suppose you are happy with @Code "fixed" +except that you want bold keywords. Then one line needs to be changed, to +@ID @Code "fixedkeywords { Bold }" +Or suppose you like @Code "varying" as it stands, but would like it to be +the default style rather than {@Code "fixed"}. Again, only one line needs +to be changed, to {@Code "style { varying }"}. +@End @Section |
