Vale¶

Vale是一个功能非常强大的 Prose Linter，除了检查markdown之外，还可以检查DITA等标记文本。

如何使用¶

安装 Vale brew install vale
在需要检查的文件的根目录下创建 .vale.ini

在 .vale.ini 中输入规则所在路径，以及需要启用的规则

StylesPath = vale-styles/
MinAlertLevel = error

[*]
BasedOnStyles = write-good
vale.Editorializing = YES
vale.Hedging = error

规则解读¶

一般技术文档中，不推荐使用被动语态，如果希望linter检查此规则，则可以使用如下规则。

识别出be动词
识别be动词后所跟词汇(tokens)

一旦匹配，即会给用户提示错误，并告诉修改的方式。

创建规则¶

Vale Studio¶

Vale 提供了一个可视化的规则编辑器 Vale Studio。

基本语法¶

# All rules should define the following header keys:
#
# `extends` indicates the extension point being used (see below for information
# on the possible values).
extends: existence
# `message` is shown to the user when the rule is broken.
#
# Many extension points accept format specifiers (%s), which are replaced by
# extracted values. See the exention-specific sections below for more details.
message: "Consider removing '%s'"
# `level` assigns the rule's severity.
#
# The accepted values are suggestion, warning, and error.
level: warning
# `scope` specifies where this rule should apply -- e.g., headings, sentences, etc.
#
# See the Markup section for more information on scoping.
scope: heading
# `code` determines whether or not the content of code spans -- e.g., `foo` for
# Markdown -- is ignored.
code: false
# `link` gives the source for this rule.
link: 'https://errata.ai/'
# The number of times this rule should raise an alert.
#
# By default, there is no limit.
limit: 1

规则示例¶

PingCAP公司是一个知名数据库公司，不少外部人士常常将公司名称写为pingcap或Pingcap等，需要一个规则文本进行检查，确保所有的文本或代码中，均使用了 PingCAP 的正确写法。

在 Styles 中新建PingCAP文件夹，并在其中新建 branding.yml 文件，并在其中输入下方规则

---
extends: substitution
message: "使用 '%s' ，而非 '%s'"
level: error
ignorecase: false
# swap maps tokens in form of bad: good
swap:
  pingcap: PingCAP
  Pingcap: PingCAP
  PingCap: PingCAP
