Keep whitespaces in RTE for pre and code tags

Question:

I want to display code through <pre> and/or tags, which works fine. White spaces are saved on first save and displayed properly in the front-end. However, when reloading the content in the backend, the editor shows the code without the additional whitespaces. Saving again drops the whole code formatting.

I assume there is some setting for this but I couldn't find anything until now. Any hints on this?

For the code highlighting, I am using the GeshiLib and vjrtecodesnippetsextensions.

<strong>Edit:</strong>

Sorry, missed the configuration. There is the basic rtehtmlarea involved, currently v4.7.5, there is no TCA specific change since it is a standard bodytext field from TYPO3's standard <em>Text content element</em> (displayed through css_styled_content).

PageTS for the RTE looks like the following:

RTE.default.hidePStyleItems := removeFromList(pre) RTE.default.proc { allowTags := addToList(pre) entryHTMLparser_db.allowTags < RTE.default.proc.allowTags overruleMode = tx_vjrtecodesnippets,ts_css,cleanenc allowTags := addToList(code) allowTagsOutside := addToList(code) entryHTMLparser_db { allowTags < RTE.default.proc.allowTags allowTagsOutside < RTE.default.proc.allowTagsOutside } HTMLparser_rte { allowTags < RTE.default.proc.allowTags allowTagsOutside < RTE.default.proc.allowTagsOutside } }

<strong>Edit2:</strong> We've published the TYPO3 extension news_blog which does exactly this.

Answer1:

I wanted to write a comment, but a short answer with sophisticated guesses might be just as good:

<ul><li>I checked at my own site, the tag works fine. Whitespaces are stored as &nbsp; in the bodytext field, therefore preserved when saved and re-opened. </li> <li>Have you tried deleting the line<br />RTE.default.hidePStyleItems := removeFromList(pre)?</li> <li>According to the <a href="http://typo3.org/extension-manuals/vjrtecodesnippets/0.0.4/view/1/2/" rel="nofollow">manual</a>, only tags are supported by vjrtecodesnippets. Do you really need <em>both</em> tags for syntax highlighting? </li> <li>Also, have you tried changing your PageTS like follows to enable <pre>?:</li> </ul>

-

RTE.default.proc { allowTagsOutside := addToList(code,pre) }

<strong>EDIT:</strong><br /> I found a related <a href="http://snipplr.com/view/9197/" rel="nofollow">TypoScript snippet</a>, which might be noteworthy for your case. Please try making the following adjustments:

In the Template SETUP section:

lib.parseFunc.allowTags := addToList(code,pre) lib.parseFunc_RTE.allowTags := addToList(code,pre)

In the PAGE TSconfig:

RTE.default.proc { allowTags := addToList(code,pre) allowTagsOutside := addToList(code,pre) overruleMode = tx_vjrtecodesnippets,ts_css,cleanenc // CONTENT TO DATABASE HTMLparser_rte { allowTags < RTE.default.proc.allowTags allowTagsOutside < RTE.default.proc.allowTagsOutside } // Entry HTML parser entryHTMLparser_db { allowTags < RTE.default.proc.allowTags allowTagsOutside < RTE.default.proc.allowTagsOutside } }

Answer2:

this works on typo3 7.4

RTE.default.proc { allowTags := addToList(pre) HTMLparser_rte { allowTags < RTE.default.proc.allowTags } entryHTMLparser_db { allowTags < RTE.default.proc.allowTags } }

for sure you can also add more tag names seperated with " , "
