On this binding we fail to disable CSI u
bind c-t '
begin
set -lx FZF_DEFAULT_OPTS --height 40% --bind=ctrl-z:ignore
eval fzf | while read -l r; echo read $r; end
end
'
because for "fzf", ParseExecutionContext::setup_group() returns early with the
parent process group (which should be fish's own) , hence "wants_terminal"
is false. This seems questionable, I don't think the eval should make a
difference here.
For now, don't touch it; use the more accurate way of detecting whether
a process may read keyboard input. In many of such cases "wants_terminal"
is false, like
echo (echo 1\n2\n3 | fzf)

# This is a very fragile test. Sorry about that. But interactively entering
|
|
# commands and verifying they are recorded correctly in the interactive
|
|
# history and that history can be manipulated is inherently difficult.
|
|

|
|
# This is meant to verify just a few of the most basic behaviors of the
|
|
# interactive history to hopefully keep regressions from happening. It is not
|

# meant to be a comprehensive test of the history subsystem. Those types of
|
|
# tests belong in the src/fish_tests.cpp module.

# The history function might pipe output through the user's pager. We don't
|

# want something like `less` to complicate matters so force the use of `cat`.
