In content management and website operations, how to ensure that information is presented to visitors in the clearest and most friendly manner is a core issue that every content operator is concerned about.AnQiCMS as an efficient content management system, provides rich features and flexible template mechanisms, including various practical filters to help us refine content processing.wordwrapEnglish translation: and the role it may play in rendering Markdown content.

I.wordwrapEnglish translation: Filter: Elegant line break for long text.

In daily content creation, we often encounter long paragraphs of text or code blocks. If not handled properly, they may exceed the container on the page, affecting the overall layout and reading experience.wordwrapThe filter is designed for this purpose, its core function is to automatically wrap a long text according to the specified character length.

Imagine, when you are using the Markdown editor in the AnQiCMS background to write a technical article, it includes a long code example or a description in English without natural breakpoints.If not processed, this content may cause a horizontal scrollbar on small screen devices or overflow in a fixed-width layout.wordwrapThe filter can be engaged to automatically insert line breaks in the text when it reaches the preset length, thereby enhancing the readability of the content and the beauty of the page.

wordwrapThe working principle of the filter is relatively intuitive: it identifies 'words' based on spaces in the text, and then attempts to wrap between words within a specified length range. This means that if your text is composed of English words separated by spaces, wordwrapIt can maintain the integrity of words very well. However, for Chinese, which is a continuous character, as there is no natural spacing.wordwrapThe filter does not force line breaks in the middle of Chinese characters. This is a feature that needs to be paid special attention to when in use.

Secondly, apply it in the AnQiCMS template.wordwrapFilter

AnQiCMS's template system is based on Django template engine syntax, making the application of filters very simple and intuitive.wordwrapThe basic usage format of the filter is:{{ 变量 | wordwrap: 长度 }}.变量is the text content you want to process,长度Is the maximum number of characters you expect per line of text.

For example, if you have an array namedlong_descriptionText variable, hope it breaks every 20 characters, you can write it like this: 

{{ long_description|wordwrap:20 }}

How is it applied in the Markdown rendering content of AnQiCMS?

Here we need to understand the process of AnQiCMS handling Markdown content. When you enable the Markdown editor and in the content field (such asarchive.Content）中输入Markdown文本后，系统在渲染页面时会将其转换为HTML。文档中提到，ContentField will automatically convert content to HTML after enabling Markdown editor, even you can specify conversion parameters manually.render=trueParameter manual specification of conversion.

An important clarification is: wordwrapFilters are designed to handleplain text strings. If you directly apply Markdown content that has already been rendered into HTML (for example,{{ archive.Content | render=true | wordwrap:20 | safe }}Using it like this), it will attempt to wrap lines within HTML tags, which is very likely to break the HTML structure and cause the page to display abnormally. Therefore,It is strongly recommended not towordwrapDirectly applied to Markdown rendering results that already contain HTML tags.

Then, in the context of Markdown rendering content,wordwrapwhere is it more suitable to apply?

  1. Process specific plain text paragraphs in Markdown source content (use with caution)： If your Markdown content field contains long paragraphs that you explicitly know are plain text (not processed automatically by Markdown syntax), and you
