Supported Codes
The following are examples of the ANSI escape codes which are supported (i.e. interpreted as a valid input) by HTMLPrinter. Note that the representation depends on the renderer, since some codes are not widely supported and there are some code conflicts.
Bold and Faint
buf = IOBuffer()
print(buf, "\e[0m", "Normal ")
print(buf, "\e[1m", "Bold ")
print(buf, "\e[2m", "Faint ") # this unsets the "bold"
print(buf, "\e[0m", "Normal ")
HTMLPrinter(buf, root_class="documenter-example-output")Normal Bold Faint Normal
Italic
buf = IOBuffer()
print(buf, "\e[0m", "Normal ")
print(buf, "\e[3m", "Italic ")
print(buf, "\e[1m", "Bold-Italic ") # this keeps the "italic"
print(buf, "\e[23m", "Bold ") # this keeps the "bold"
print(buf, "\e[0m", "Normal ")
HTMLPrinter(buf, root_class="documenter-example-output")Normal Italic Bold-Italic Bold Normal
Underline and Strikethrough
buf = IOBuffer()
print(buf, "\e[0m", "Normal ")
print(buf, "\e[4m", " Underline ", "\e[24m", " ")
print(buf, "\e[9m", " Striethrough ", "\e[29m", " ")
print(buf, "\e[4;9m", " Both ", "\e[m")
HTMLPrinter(buf, root_class="documenter-example-output")Normal Underline Striethrough Both
Invert
The invert code swaps the foreground and background colors. However, the support is limited. You will need to force the foreground and background colors to be switched manually, or convert the style afterwards using JavaScript etc.
buf = IOBuffer()
print(buf, "\e[0m", "Normal ")
print(buf, "\e[7m", "Invert ")
print(buf, "\e[27m", "Normal ")
print(buf, "\e[7;100m", "GrayText? ") # not supported by default.css
print(buf, "\e[34m", "BlueBG? ") # not supported by default.css
print(buf, "\e[0m", "Normal ")
HTMLPrinter(buf, root_class="documenter-example-output")Normal Invert Normal GrayText? BlueBG? Normal
Conceal
buf = IOBuffer()
print(buf, "\e[0m", "Normal ")
print(buf, "\e[8m", "Conceal ")
print(buf, "\e[31;47m", "Red1 ") # this is still concealed
print(buf, "\e[0m", "Normal ")
print(buf, "\e[31;47m", "Red2 ")
print(buf, "\e[8m", "Conceal ")
print(buf, "\e[28m", "Red3 ")
print(buf, "\e[0m", "Normal ")
HTMLPrinter(buf, root_class="documenter-example-output")Normal Conceal Red1 Normal Red2 Conceal Red3 Normal
16 colors
The 16 colors correspond to the color symbols which can be specified in the argument of printstyled (e.g. :black, :red, :green, :light_blue). Their sRGB values are environment-dependent. This document defines their actual colors in a CSS file.
Basic colors
buf = IOBuffer()
for fg in [30:37; 39] # foreground color
for bg in [40:47; 49] # background color
print(buf, "\e[$fg;$(bg)m $fg; $bg ")
end
println(buf)
