在 Scala Repl 中暂时禁用制表符补全 [英] Temporarily disable tab completion in Scala Repl

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 命令指示解释器至少暂时将选项卡作为普通空格处理 - 沿着 :paste 行?

I occasionally work with code that has hard tabs instead of spaces. Is there any repl command to instruct the interpreter to process the tabs as normal whitespace at least temporarily - along the lines of :paste ?

推荐答案

确实 :paste 听起来是个不错的选择，但如果你真的想覆盖键绑定，你可以提供你自己的设置文件，如下所示:

Indeed :paste sounds like a good option but if you really want to override keybindings you can provide your own settings file like this:

scala -Djline.keybindings=myfile

我从默认的scala jar里查到的文件格式是这样的:

The format of the file that I looked up from default scala jar is like this:

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.

Replace the command matching option 9 with empty string.
