@Section
@Title { Changing the default values }
@Tag { cpsetup }
@Begin
@PP
We have just seen that the @Code "@CP" symbol has many options for
changing the appearance of the C text. 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 }"}.
