测量英文文本可读性的工具

是否有一个命令行程序来获取包含英文文本的文件，分析该文本并输出其可读性分数？

例如，如果向程序输入文本，则程序应输出Flesch-Kincaid等级级别，McLaughlin的SMOG等级等。

我相信官方存储库中存在这样的程序，但是我不记得它的名字。还有可能我误会了。

该diction 软件包包含一个名为的工具style：

Style 分析文档写作风格的表面特征。它打印各种可读性等级，单词，句子和段落的长度。它可以进一步定位具有某些特征的句子。

例如，如果我评估您的问题正文（保存在file中flux_question）以打印可读性指数（ARI）超过10的句子：

$ style -r 10 flux_question
flux_question:1: Is there a command line program that takes a file containing English text, analyzes the text, and outputs its readability scores?
flux_question:2: For example, if one feeds the program a text, the program should output the Flesch-Kincaid grade level, McLaughlin's SMOG grading, etc.
readability grades:
        Kincaid: 10.2
        ARI: 10.8
        Coleman-Liau: 12.5
        Flesch Index: 51.1/100
        Fog Index: 12.0
        Lix: 48.6 = school year 9
        SMOG-Grading: 11.2

        verb types:
        to be (1) auxiliary (2) 
        types as % of total:
        conjunctions 5% (3) pronouns 9% (6) prepositions 2% (1)

sentence beginnings:
        pronoun (1) interrogative pronoun (0) article (0)
        subordinating conjunction (0) conjunction (0) preposition (0)

要过滤输出，您可以使用例如tail -n8仅获取成绩或grep 'Flesch\|SMOG'仅打印Flesch Index和SMOG-Grading：

$ style style_test | grep 'Flesch\|SMOG'
        Flesch Index: 51.7/100
        SMOG-Grading: 11.2
