export to html, colored dates: org-mime export works but org to html does not

export to html, colored dates: org-mime export works but org to html does not

[Uwe Brauer]

Hi

The following drives me a bit crazy.

I have two functions, one for email.


(defun my-color-red-html ()
  (interactive)
  (while (re-search-forward "#\\([^#]*\\)#" nil t)
    (replace-match "<span style=\"color:red\">\\1</span>")))

I put this function into  two hooks

  (add-hook 'org-mime-html-hook 'my-color-red-html)


(defun my-html-red (text backend info)
    (when (org-export-derived-backend-p backend 'html)
      (replace-regexp-in-string "#\\([^#]*\\)#"
				"<span style=\"color:red\">\\1</span>"
				text)))

  (add-to-list 'org-export-filter-plain-text-functions 'my-html-red)

Now if I have 
#<2023-02-11>#
in an email it gets replaced by 

<span style="color:red"><span class="timestamp-wrapper"><span class="timestamp"> 11.02.2023 </span></span></span>


But if I have 
#<2023-02-11>#
in an org file and export it to html, no color is added to the timestamp.

I don't know how to debug this.

Any idea?

Regards

In org, "<2023-02-11>" is a date, not plain text. Thus, your function
doesn't get called with a text matching your date.

Note that using macros, you could get almost what you want. 

#+MACRO: IDATE @@html:<span style="color: red">$1</span>@@

{{{IDATE(<2023-02-11>)}}}

And maybe ther is a way to also customize date format to get rid of the
brackets.

You forgot to specify IDATE macro name.

Oops that is true. Sorry, Now it works, but it does not do what I expect

I obtain 


<span style="color: red"><2023-02-11></span>

But I would like to having the same result org-mime obtains

Namely 

<span style="color:green"><span class="timestamp-wrapper"><span class="timestamp"> 11.02.2023 </span></span></span>

Any chance to get that also?

It does work. It's just that default css style for timestamps sets the
color of its own.

Thanks!

#+OPTIONS: html-style:nil

Works, maybe is too blunt, but good enough for me

I even did! :-)

You need to call the macro named 'IDATE' like this:

     * Title {{{IDATE(2023-02-11)}}}
     {{{IDATE(2023-02-11)}}}

See:
   (info "(org) Macro Replacement")

And it will work for you too.
