Font
Hugo allows some font control to enhance your text. Options include:
- Boldface
- Italics
- Underline
- Proportional Text
- Mono-spaced Text
- Colors
Changing Fonts
There are two ways to change the font in your printed text, either by
using the Font() routine or embedding control characters in the text
itself. It is generally recommended to use the Font() routine over
embedded codes for readability.
Font() routine
The Font() routine takes constants (defined in
the standard library)
| Constant | Effect |
|---|---|
| BOLD_ON | to start bold text |
| BOLD_OFF | to stop bold text |
| ITALIC_ON | to start italic text |
| ITALIC_OFF | to stop italic text |
| UNDERLINE_ON | to start underlined text |
| UNDERLINE_OFF | to stop underlined text |
| PROP_ON | Start proportional printing |
| PROP_OFF | Stop proportional printing |
Example:
...INSIDE SOME ROUTINE SOMEWHERE...
Font(BOLD_ON)
"This text will print bold, "
Font(BOLD_OFF)
"but this text will not."
! You can also combine the effects thusly
Font(BOLD_ON | UNDERLINE_ON)
"This text will print Bold AND underlined."
Font(BOLD_OFF)
"And this text will just be underlined."
Font(UNDERLINE_OFF)
"Back to normal text."
...
The output of this program will look something like this (for interpreters that support it):
This text will print bold.
But this text will not.
This text will print Bold AND underlined
And this text will just be underlined.
Back to normal text

Embedded Control Codes
The following control codes are used for embedded text:
| Control Code | Effect |
|---|---|
| \B | Start bold text. |
| \b | End bold text. |
| \I | Start italic text. |
| \i | End italic text. |
| \U | Start underlined text. |
| \u | End underlined text. |
Example (to match the output of the previous example):
"\BThis text will print bold,\b "
"but this text will not."
! You can also combine the effects thusly
"\B\UThis text will print Bold AND underlined.\b\nAnd this text will just be underlined.\u"
! \n is the newline character
"Back to normal text."
Text Colors
The color command changes the color of the text and/or the background. Giving only a foreground color will result in colored text with the same background color. For example:
color LIGHT_RED
print "WARNING! WARNING!"
color TEXTCOLOR ! go back to the regular text color
