This supports now curly, double, dashed, and dotted underline styles
where trhe terminal supports it. This works well on Windows Terminal,
reasonably on iTerm2, Alacritty, Kitty, and probably others.
The wasm mode terminal includes support for this, dependent on the browser
capabilities.
The macOS Terminal just changes the background color. Legacy Windows
console does nothing.
We will try to provide a regular underscore as a fallback. A new style.go
demo is included to see some style combinations.
This fix is not perfect, in that it will not fix every terminal that has
automargin support, but it fixes the *vast* majority of them by eliminating
the hacky workaround for the automargin - essentially using the rmam capability
to disable automatic wrapping at the margin.
This adds optional MouseFlags that can be used to adjust what is
tracked for mouse reporting (leaving the other modes to be handled
by the terminal.) This should work on all XTerm style terminals,
but on Windows we have no way to be selective here.
This replaces high numbered function keys on xterm style
emulators with modifiers. So pressing SHIFT-ALT-F1 is
reported as exactly that, for example. This also extends
that to the insert, delete, home, end, etc.
There is a chance that this will break some emulators --
of particular concern are older VTE based emulators and
rxvt (and derivatives). However, we think that most VTE
derivatives are now much more closely aligned to xterm.
The Wyse50 alternate character set was changed (likely
due to a bug fix in ncurses).
Implemented key kombination of Shift + PgUp/PgDn for Gnome terminal.
Same combination copied to all other terminal implementations which use same
codes for Shift + Up/Down but since this is tested on Ubuntu 16.04 with Gnome
Terminal 3.18.3 it could be that it is not correctly implemented for some of the
other terminals.
I have rerun gen.sh having pulled the latest tcell to include this PR:
https://github.com/gdamore/tcell/pull/325.
I am using Ubuntu 19.04 - running gen.sh changed more fields than just
those impacted by the above fix. I've removed those from this commit. (I
verified that gen.sh changed those fields I've removed without the fix
above, so it's not related). Based on TERMINALS.md, I suspect you
regenerate these typically on a Debian machine(?)
