[英]Elixir's mix format ignores line length option
I have an Elixir project .formatter.exs
file in my project root that looks like this:我的项目根目录中有一个 Elixir 项目
.formatter.exs
文件,如下所示:
[
line_length: 120,
inputs: ["mix.exs", "config/*.exs"],
subdirectories: ["apps/*"]
]
But as best I can tell, the line_length
parameter is being ignored.但据我所知,
line_length
参数被忽略了。
Given the following code, the longest line (whose length is 102 characters) is always being split into two lines (with the when
clause wrapped to the new line):给定以下代码,最长的行(长度为 102 个字符)总是被分成两行(
when
子句包装到新行):
defmodule SomeModule do
def lookup_data(parameter1, parameter2) when is_integer(parameter1) and is_integer(parameter2) do
:not_implemented
end
end
In contrast, if I copy & paste the module into the online Elixir formatter and set the line length option to 120, I get no changes to the text (as expected).相比之下,如果我将模块复制并粘贴到在线 Elixir 格式化程序中并将行长度选项设置为 120,则不会对文本进行任何更改(如预期)。
I must have screwed up the .formatter.exs
somehow, but for the life of me I can't figure out how.我一定是搞砸了
.formatter.exs
不知何故,但对于我的生活,我无法弄清楚如何。
In the mix format docs , it notes that if your top-level .formatter.exs
lists subdirectories (mine has "apps/*"
), the rules from the top-level formatter won't be used in those subdirectories.在mix format docs 中,它指出,如果您的顶级
.formatter.exs
列出了子目录(我的有"apps/*"
),则顶级格式化程序中的规则将不会在这些子目录中使用。
The solution was to edit apps/[my_app]/.formatter.exs
(which had been auto-generated by mix new
previously) with the line length parameter:解决方案是使用
apps/[my_app]/.formatter.exs
编辑apps/[my_app]/.formatter.exs
(之前由mix new
自动生成):
[
line_length: 120
