It may be useful to some to have the terminal emit an error character
to show unknown escape sequences. Off by default, unknown escape sequences
are silently ignored. If enabled, '¿' is inserted instead.
This is basically a rewrite of the ESC handler, keeping state
in the class, so ESC sequences can continued between called
to append() (such as when reading data from a pipe in blocks).
New private class 'Fl_Escape_Seq' handles parsing and state info.
It also has careful bounds checking during parsing.
Backspace supports Unicode, and the unicode chars can straddle
across append() operations as well.
Private variables in Fl_Simple_Terminal renamed _xxx to xxx_
to improve CMP compliance.
- remove obsolete svn '$Id$' tags from all source files
- update .fl files and generated files accordingly
- replace 'http://www.fltk.org' URL's with 'https://...'
- replace bug report URL 'str.php' with 'bugs.php'
- remove trailing whitespace
- fix other whitespace errors flagged by Git
- add and/or fix missing or wrong standard headers
- convert tabs to spaces in all source files
The only relevant code changes are in the fluid/ folder where
some .fl files and other source files were used to generate
the '$Id' headers and footers.
