Still to do: rename fl_filename... to fl_filename..._str
and introduce into core library.
|
|
|

|
- Add 'int Fl_Terminal::handle_unknown_char(int drow, int dcol)'
to write the "unknown" character to the intended display position.
- Define Fl_Terminal::unknown_char as a static variable to avoid
redundancy. In the future this might be overridden by users.

Some old platforms (NetBSD, AIX) implement the common stdio "putchar()"
function as a global macro which poisons the global namespace, preventing
all C and C++ programs from using "putchar()" as a function or method.
There was a long thread about this in fltk.coredev during the period
Mar 25 2024 ~ Apr 4 2024, subject "RFC: Fl_Terminal::putchar() in public API"
as to why we have no choice but to not use putchar() as a method name.

Three unrelated but only minor warnings.

... and document a missing parameter.

This involved enlarging the unittest main window to make room
for the additional test.
Adding this test revealed a problem in Fl_Terminal's global
scrollbar size handling, which is fixed here as well.
Also fixed a small issue in the demo's debugging terminal
with the horiz scrollbar.

Fixed a bug in the handling of xterm color 39 + 49, which avoids
applying Dim/Bold if default color is the special "see through" color
0xffffff00. A test will be added to test/terminal to excercise this
in a follow up commit.
Renamed CharStyle::?gcolor_uchar() -> CharStyle::?gcolor_xterm()
for a consistent naming convention.
Changed fltk_fg_color() from a static func to a CharStyle method
because it needs to access the defaultcolor for the special cases
for xterm colors 39 and 49.
Made CharStyle::attr_color() private, as per Jonathan Griffitts request
in issue #909.
Improved docs regarding effects of Dim/Bold for xterm and non-xterm color
methods.
Fl_Terminal::text?gcolor_xterm() methods now use CharStyle::?gcolor_xterm()
methods, removing the duplicate code logic.

- Made sure all public+protected members are documented.
- Reclassified some private -> protected:
> vscroll_width()
- Removed signatures for unimplemented (non-existant) methods:
> u8c_cursor(void)
> history_use(int,bool)
> cursor_h()
- Reclassified some protected -> private:
> x_to_glob_col()
> xy_to_glob_rowcol()
> is_hist_ring_row()
> is_disp_ring_row()
> handle_ctrl()
> is_printable()
> is_ctrl()
..etc..
> handle_selection_autoscroll()
> handle_selection()
> is_redraw_style
- Add todo for ESC 7 and ESC 8
- Small code formatting mods
- Small typos

New public methods:
void clear(void);
void clear(Fl_Color val);
old protected methods made public:
void clear_screen(bool scroll_to_hist=true); // ESC [ 2 J
void clear_screen_home(bool scroll_to_hist=true); // ESC [ H ESC [ 2 J
void cursor_home(void); // ESC [ 0 H
test/terminal modified to test these, and added separate tests
for both the API and ANSI code ways to do these ops.

textcolor() needed for consistency, color() behavior documented.
Both added to the test/terminal app.
Elaborated on the special background "see through" color value + behavior,
tested with color() in test/terminal app.
