【问题描述】:
我偶尔会使用带有硬制表符而不是空格的代码。是否有任何 repl 命令来指示解释器至少暂时将制表符处理为普通空格 - 沿着 :paste 的行?

确实:paste 听起来是个不错的选择,但如果您真的想覆盖键绑定,您可以提供自己的设置文件,如下所示:
scala -Djline.keybindings=myfile
我从默认 scala jar 中查找的文件格式如下:
来自jline.jar中的文件scala/tools/jline/keybindings.properties:
# Keybinding mapping for JLine. The format is:
# [key code]=[logical operation]
# CTRL-A: move to the beginning of the line
1=MOVE_TO_BEG
# CTRL-B: move to the previous character
2=PREV_CHAR
# CTRL-D: close out the input stream
4=EXIT
# CTRL-E: move the cursor to the end of the line
5=MOVE_TO_END
# CTRL-F: move to the next character
6=NEXT_CHAR
# CTRL-G: abort
7=ABORT
# BACKSPACE, CTRL-H: delete the previous character
# 8 is the ASCII code for backspace and therefor
# deleting the previous character
8=DELETE_PREV_CHAR
# TAB, CTRL-I: signal that console completion should be attempted
9=COMPLETE
将匹配选项 9 的命令替换为空字符串。
