In-Reply-To: <20220603142521.42863-1-joak-pet@online.no> (Joakim Petersen's message of "Fri, 3 Jun 2022 16:25:21 +0200")
This is not a new issue, but seeing this:
if [ $detached = no ]; then
branch_color="$ok_color"
else
branch_color="$bad_color"
fi
c="$branch_color$c"
z="$c_clear$z"
if [ "$w" = "*" ]; then
w="$bad_color$w"
fi
if [ -n "$i" ]; then
i="$ok_color$i"
fi
if [ -n "$s" ]; then
s="$flags_color$s"
fi
if [ -n "$u" ]; then
u="$bad_color$u"
fi
+ if [ -n "$p" ]; then
+ p="$c_clear$p"
+ fi
+ if [ -n "$sparse" ]; then
+ sparse="$c_clear$sparse"
+ fi
r="$c_clear$r"
}
it makes me wonder if the more forward looking and future-proof way
that is resistant to any future and random reshuffling like what
0ec7c23c (git-prompt: make upstream state indicator location
consistent, 2022-02-27) did would be to make it a rule to maintain
that there is no coloring by default, and when any of these tokens
like w, i, s, ... are not empty, enclose them inside "color-on" and
"color-off" sequence.
For example,
if [ "$w" = "*" ]; then
w="$bad_color$w"
fi
would mean $w, when it is "*", would cause gitstring to contain an
asterisk that is painted in $bad_color, but ALSO causes whatever
that happens to come AFTER $w in gitstring to be painted in the same
color UNLESS it tries to protect itself. Right now, $w may be
immediately followed by $i, and $i does protect itself by prefixing
with $ok_color, but if $i is empty, $w's coloring will extend to $s.
So, if we did this instead:
- z="$c_clear$z"
if [ "$w" = "*" ]; then
- w="$bad_color$w"
+ w="$bad_color$w$c_clear"
fi
and make similar changes to everything else we see above, we
probably can lose the ones that prefix with $c_clear, because each
token that paints itself in unusual color is now responsible for
returning the terminal state to normal with the $c_clear sequence
after it is done with it. We do not have to special case sparse, p,
or r in this helper function at all if we go that route, no?
If the helper were written that way, then reshuffling the order of
the tokens done in 0ec7c23c (git-prompt: make upstream state
indicator location consistent, 2022-02-27) wouldn't have made the
patch under discussion necessary at all, which is what I see is
valuable from the "maintainability" point of view.
