It is recommended that accessing features such as setting text colors and cursor positioning
is best done with ANSI/XTERM escape sequences. But if one sets ansi(false) then this is
not possible. Many commonly used API functions are public, such as textfgcolor() for setting
not possible, so the public API can be used for common operations, e.g.
\par
Public API | ESC code equivalent | Description |
------------------------|--------------------------|-----------------------------|
clear_screen_home() | ESC [ H ESC [ 2 J | Clear screen, home cursor |
cursor_home() | ESC [ H | Home the cursor |
clear_history() | ESC [ 3 J | Clear scrollback history |
reset_terminal() | ESC [ c | Reset terminal |
To access more advanced API calls, one can derive a class from Fl_Terminal to
access protected methods manipulate the terminal more directly, e.g.
\par
Protected API | ESC code equiv. | Description |
-----------------------------|------------------|-----------------------------------------|
current_style() | ESC [ # m | Set text attributes |
clear_eod() | ESC [ 0 J | Clear from cursor to end of display |
clear_sod() | ESC [ 1 J | Clear from cursor to start of display |
clear_eol() | ESC [ 0 K | Clear from cursor to end of line |
clear_sol() | ESC [ 1 K | Clear from cursor to start of line |
clear_line() | ESC [ 2 K | Clear line cursor is on |
scroll(int) // >0 for up | ESC [ 1 S | Scroll up one line |
scroll(int) // <0 for down | ESC [ 1 T | Scroll down one line |
cursor_left() | ESC [ 1 D | Move cursor left (no wrap) |
cursor_right() | ESC [ 1 C | Move cursor right (no wrap) |
cursor_up() | ESC [ 1 B | Move cursor up (no scroll or wrap) |
cursor_down() | ESC [ 1 A | Move cursor down (no scroll or wrap) |
cursor_row() cursor_col() | ESC [ # ; # H | Move cursor to row# / column# |
insert_char() | ESC [ # @ | Insert a char at cursor position |
delete_chars() | ESC [ # P | Delete chars at cursor position |
insert_rows() | ESC [ # L | Insert rows at cursor position |
delete_rows() | ESC [ # M | Delete rows at cursor position |
etc... | etc... | etc... |
Many commonly used API functions are public, such as textfgcolor() for setting
text colors. Others, such as cursor_up() are protected to prevent common misuse, and are
available only to subclasses.
