How to use multiline command in 'script:' with YAML?
提问by hgiesel
I have a repository that uses Travis CI, and in the .travis.ymlthere I have this line:
我有一个使用 的存储库，Travis CI在.travis.yml那里我有这一行：
script:
- vim -Nu <(cat <<-EOF
set nocompatible |
filetype off
EOF
) -c 'Script' > /dev/null
Sadly this doesn't work, as this is transformed into a single line and is executed like this:
遗憾的是这不起作用，因为它被转换成一行并像这样执行：
vim -Nu <(cat <<-EOF set no compatible | filetype off | EOF ) -c 'Script' > /dev/null
This makes the EOFtag not working, as EOFneeds to be in a single line.
An alternative would be to just use normal quotes like this:
这使得EOF标签不起作用，因为EOF需要在一行中。另一种方法是使用这样的普通引号：
script:
- vim -Nu <(cat 'set nocompatible |
filetype off
) -c 'Script' > /dev/null
Which works, and is fine, but I feel there must be a way to insert newlines into a .travis.yml. I have an alternative now, but I may not in the future. So how do you do it?
哪个有效，并且很好，但我觉得必须有一种方法可以将换行符插入.travis.yml. 我现在有一个选择，但我可能不会在未来。你是怎么做到的？

In YAML you can specify newlines in a scalar by using ""quoting and escaping the newlines (\n), or, and that is more natural for your case, by using a literal style block scalar:
在 YAML 中，您可以通过使用""引用和转义换行符 ( \n)来指定标量中的换行符，或者，对于您的情况更自然，使用文字样式块标量：
script:
- |
vim -Nu <(cat <<-EOF
set nocompatible |
filetype off
EOF
) -c 'Script' > /dev/null
This is a scalar starting with a line with a |(pipe symbol), followed by multiple lines for which the line-breaks are preserved.
这是一个标量，以带有|（管道符号）的行开头，后跟保留换行符的多行。
- The lines are normally indented (exception: a single top-level literal style block scalar).
- After the
|there can be modifiers:1-9, used when your first line starts with spaces;+,-to influence stripping of final newlines (normally collapsed into one).
- 这些行通常是缩进的（例外：单个顶级文字样式块标量）。
- 后面
|可以有修饰符：1-9，当你的第一行以空格开头时使用；+,-影响最终换行符的剥离（通常折叠为一个）。

I use the folded block styleto achieve exactly the desired effect:
我使用折叠块样式来达到完全想要的效果：
script:
- >
valgrind
--read-var-info=yes
--error-exitcode=1
--fullpath-after=
--track-origins=yes
--leak-check=full
--num-callers=20
--suppressions=$(pwd)/tests/zephir_parser.3.7.0.sup
$(phpenv which php)
-d variables_order=EGPCS
run-tests.php
-p $(which php)
-d extension=$(pwd)/modules/zephir_parser.so
-d variables_order=EGPCS
-g "FAIL,XFAIL,BORK,WARN,LEAK,SKIP"
