In the template design of AnQi CMS, managing the display of text content is a key factor in enhancing user experience. Wherein,wordwrapThe filter is a practical tool for processing long text, which can help us automatically wrap the output content according to the set length.However, it shows some unique and notable characteristics when dealing with multi-language long texts, especially when facing languages like Chinese, Japanese, and Korean (CJK).

wordwrapThe core function and mechanism of the filter

First, let's take a look back atwordwrapFilter basic function.Its design intention is to insert a line break automatically when a continuous text reaches a specified character length, thus avoiding layout problems caused by overly long text, such as bursting the layout in a narrow page.{{ obj|wordwrap:number }}is called in the form of,numberSpecified the maximum number of characters per line.

The core mechanism of this filter lies in how it "identifies" the boundary of a word—it mainly relies on spaces as the default word separator. For example, when we applywordwrapThe filter tries to break lines between words to maintain the integrity of the words.If a word itself exceeds the set length, it will be forced to wrap within the word to ensure that each line does not exceed the maximum character count.

English text processing features: Focus on CJK languages

When we turn our attention to multilingual environments, especially languages like Chinese, Japanese, and Korean that do not use spaces for natural word separation,wordwrapThe performance of the filter presents its unique characteristics.

Since the character stream of these languages is continuous,wordwrapFilter cannot find an explicit 'word' boundary.It treats a continuous segment of Chinese text as a "very long word".wordwrap:10），if there is no English, number, punctuation or other characters that can be used as delimiters in the text,wordwrapThe filter will not force line breaks between Chinese characters. It will only handle those Western words that are clearly separated by spaces.

Give an example, suppose you have a Chinese text "Anqi CMS is committed to providing an efficient and customizable content management system to help enterprises carry out content marketing efficiently", and try to usewordwrap:10Be processed.The result is likely that the original text, except for the English word 'CMS' and numbers which may be separated, other consecutive Chinese parts will not be automatically broken according to the length you set, and will remain on one line until punctuation or English is encountered.wordwrapThis will be wrapped at these delimiters.

Application and consideration in practice

UnderstandwordwrapThe filter's multilingual, especially CJK text processing feature, is crucial for our website content layout.

  • For languages separated by spaces (such as English, French, etc.):wordwrapFilter is a very effective tool, which can elegantly handle long texts, maintain the integrity of words, and ensure a good reading experience.
  • For CJK languagesIf you expect to force line breaks at fixed intervals in a continuous Chinese text, thenwordwrapFilter may not meet your needs. In this case, you need to consider other solutions, such as using CSS styles (such asword-break: break-all;orword-wrap: break-word;）to force the text to break at any character, or pre-process the text manually before publishing content by inserting line breaks using a program or editor.Of course, when using CSS to force word breaks, one also needs to pay attention to its possible impact on the aesthetics of typesetting.

In general, the CMS of Anqi iswordwrapFilter is a tool optimized for languages separated by spaces.In multilingual content operations, especially when dealing with Chinese text, which is not separated by spaces, we need to clearly understand its working principles and limitations, and choose the most suitable text processing strategy according to actual needs to ensure that the presentation of the website content is both beautiful and easy to read.

Common Questions (FAQ)

1.wordwrapCan the filter be used for Chinese text? If so, under what circumstances is it effective? wordwrapThe filter can be used for Chinese text, but its line-breaking behavior is limited to when it encounters English, numbers, or half-width punctuation symbols as separators.For continuous Chinese characters, it treats a long string of Chinese characters as a single 'word', and does not automatically wrap it. Even if the line break length is reached, it does not automatically wrap.

2. I want long Chinese articles to automatically wrap every N characterswordwrapcan the filter do that?Unfortunately,wordwrapThe filter itself cannot implement a forced line break 'every N characters' between consecutive Chinese characters.This is because Chinese does not have a natural word separator (space).word-break: break-all;orword-wrap: break-word;）or by other program logic to preprocess text before entering or outputting content.

3.wordwrapThe filter will process HTML tags? If I have a text with HTML, how can I ensure that it wraps correctly? wordwrapFilter is applied to plain text strings. If your text contains HTML tags,wordwrapIt will also count the label characters in the length and may wrap at label positions, potentially破坏HTML structure. To properly handle text with HTML, you usually should first usestriptags(Remove all HTML tags) orremovetagsFilter that removes specified HTML tags will strip HTML first, then applywordwrap, or not using any at allwordwrapThe line break of HTML content is handled by CSS instead.
