#ifndef Fl_Simple_Terminal_H
#define Fl_Simple_Terminal_H
#include "Fl_Export.H"
#include <FL/Fl_Text_Display.H>
/**
This is a continuous text scroll widget for logging and debugging
output, much like a terminal. Includes printf() for appending messages,
a line limit for the screen history size, ANSI sequences to control
text color, font face, font weight and font size.
This is useful in place of using stdout/stderr for logging messages
when no terminal is available, such as when an application is invoked
from a desktop shortcut, dock, or file browser.
Like a regular console terminal, the vertical scrollbar 'tracks'
the bottom of the buffer as new output is added. If the user scrolls
away from the bottom, this 'tracking' feature is temporarily suspended,
so the user can browse the terminal history without fighting the scrollbar
when new text is added asynchronously. When the user returns the
scroller to the bottom of the display, the scrollbar's tracking resumes.
Features include:
- history_lines(int) can define a maximum size for the terminal screen history
- stay_at_bottom(bool) can be used to cause the terminal to keep scrolled to the bottom
- ansi(bool) enables ANSI sequences within the text to control text colors
- style_table() can be used to define custom color/font/weight/size combinations
What this widget is NOT is a full terminal emulator; it does NOT
handle stdio redirection, pipes, pseudo ttys, termio character cooking,
keyboard input processing, screen addressing, random cursor positioning,
curses(3) compatibility, or VT100/xterm emulation.
It is a simple text display widget that leverages the features of the
Fl_Text_Display base class to handle terminal-like behavior, such as
logging events or debug information.
Example use:
\code
#include <FL/Fl_Simple_Terminal.H>
:
tty = new Fl_Simple_Terminal(...);
tty->ansi(true); // enable use of "\033[#m"
:
tty->printf("The time is now: \033[32m%s\033[0m", date_time_str);
\endcode
Example application:
\dontinclude simple-terminal.cxx
\skip //START
\until //END
Style Tables For Color/Font/Fontsize Control
--------------------------------------------
Internally this widget derives from Fl_Text_Display, and therefore
inherits some of its idiosyncracies. In particular, when colors
are used, the base class's concept of a 'style table' is used.
The 'style table' is similar to a color mapped image; where each
pixel is a single value that is an index into a table of colors
to minimize per-pixel memory use.
The style table has a similar goal; since every character in the
terminal can potentially be a different color, instead of managing
several integer attribute values per-character, a single character
for each character is used as an index into the style table, choosing
one of the available color/font/weight/size values available.
This saves on as much as 3 to 4 times the memory use, useful when
there's a large amount of text.
When ansi() is set to 'true', ANSI sequences of the form "\033[#m"
can be used to select different colors, font faces, font weights (bold,italic..),
and font sizes, where '#' is the index number into the style table. Example:
\code
"\033[0mThis text uses the 1st entry in the style table\n"
"\033[1mThis text uses the 2nd entry in the style table\n"
"\033[2mThis text uses the 3rd entry in the style table\n"
etc..
\endcode
There is a built-in style table that provides some
commonly used ANSI colors for "\033[30m" through "\033[37m"
(blk,red,grn,yel,blu,mag,cyn,wht), and a brighter version of those
colors for "\033[40" through "\033[47m". See ansi(bool) for more info.
You can also supply a custom style table using
style_table(Style_Table_Entry*,int,int), allowing you to define
your own color/font/weight/size combinations. See that method's docs
for more info.
All style index numbers are rounded to the size of the style table
(via modulus) to protect the style array from overruns.
