如何在单行ZSH中重新运行内联循环(类似bash的行为)

Question

我想知道是否有一种方法可以让zsh中的内联循环像bash中的一样。

我最近开始使用zsh，到目前为止我很喜欢它。在zsh中有一件事我希望能像在bash中一样，内联循环。

我经常运行这样的快速循环:for in a b c -> hit enter -> do -> hit enter等等…

当我回想起在zsh中要更改的命令/循环时，行被包装成多行，但在bash中它只是一行。

ZSH initial run:

user@localhost > for i in {a..c}
for> do
for> echo ${i}
for> done
a
b
c

ZSH repeat <向上箭头>:

user@localhost > for i in {a..c}
do
echo ${i}
done

BASH初始运行:

[user@localhost ~]$ for i in {a..c}
> do
> echo ${i}
> done
a
b
c

BASH repeat <向上箭头>:

[user@localhost ~]$ for i in {a..c}; do echo ${i}; done

在Zsh指南中有一个可爱的选项:它是singlelinezle选项;设置这个会导致"…编辑为[被限制到]一行，"启用您在问题中提到的所需行为。

# without `singlelinezle` set
user% for a in a b c; do echo $a; done
# output:
# a
# b
# c
# <up-arrow>
user% for a in a b c; do echo $a; done
user% for a in a b c; do
for> echo $a; 
for> done
# output: 
# a 
# b
# c
# <up-arrow>
user% for a in a b c; do
echo $a
done
setopt singlelinezle
# with `singlelinezle` set
user% for a in a b c; do echo $a; done
# output:
# a 
# b
# c
# <up-arrow>
user% for a in a b c; do echo $a; done

user% for a in a b c; do
for> echo $a
for> done
# output:
# a
# b
# c
# <up-arrow>
user% for a in a b c; donecho $andone
unsetopt singlelinezle
