Customizing ODT output from mk4ht oolatex

Question

Inspired by the custom environments created from the cfg file referenced during mk4ht oolatex test.tex custom.cfg compilations as demonstrated in the answer Configure tex4ht/oolatex output

I'm wondering how far this can be taken. For example, starting with the test code in the aforementioned question, I've been unable to get any actual changes like font size changes or font changes to the text of this quote environment. Some change efforts are seen below in the lightly modified MWE. Specifically, I've tried to insert: style:font-name="Times New Roman" and fo:font-size="18pt" but I see no change to my odt file. I've tried a dozen or so logical variations to "font-name" like:

• font
• font-name
• fonts
• font-face
• font-family

but none have changed my formatting. The document compilation didn't crash either, so I'm not even sure if I'm successfully using this part of the cfg file.

Is there a list of oolatex parseable style properties anywhere in the documentation that I've missed?

\usepackage[T1]{fontenc}
\begin{document}
This is a normal paragraph.

\begin{quote}
This is an blockquote.
\end{quote}

Another paragraph.
\end{document}

Ultimately I'd like to be able to control:

• fonts
• font sizes
• margin formatting
• paragraph spacing and alignment type (i.e. square or ragged)
• heading enumeration
• continuous section breaks
• column control (number of columns, spacing, etc)

But, baby steps in customizing styles (xml? or css?) in these office documents.

Answer 1

I think that font changes must be done in <style:text-properties> child element of <style:style>. See a list of possible attributes, another list. I cannot find any human readable description unfortunately. Anyway, try this:

\Preamble{xhtml}

  \makeatletter
\ConfigureEnv{quote}
   {\ifvmode \IgnorePar\fi \EndP}
   {\ifvmode \IgnorePar\fi\EndP\par\ShowPar}
   {\EndP \ifvmode \IgnorePar\fi
    \bgroup \Configure{HtmlPar}
   {\EndP \HCode{<!--l. \the\inputlineno-->%
   <text:p text:style-name="quote\if@rl-rtl\fi">}}
   {\EndP \HCode{<!--l. \the\inputlineno-->%
   <text:p text:style-name="quote\if@rl-rtl\fi">}}
   {\HCode{</text:p>}}
   {\HCode{</text:p>}}%
   }
   {\IgnorePar\EndP \egroup \ShowPar \ShowIndent}
\ConfigureOO{quote}{\Hnewline
<style:style style:name="quote"
             style:family="paragraph"

             fo:margin-right="1cm"
             fo:margin-top="0.199cm"
             fo:margin-bottom="0.199cm"
             fo:text-indent="0cm"
             style:auto-text-indent="false"/>\Hnewline
<style:text-properties 
             fo:font-size="18pt"
             style:font-name="Times New Roman"

</style:style>
\Hnewline <style:style style:name="quote-trl"
             style:family="paragraph"

This is the result:

Edit November 2018:

make4ht can output ODT file directly now, with filter support. So the code bellow can be simplified significantly:

local filter = require "make4ht-filter"

local process = filter {
  function(content)
    content = content:gsub("<office:font%-face%-decls>", [[<office:font-face-decls>
    <style:font-face style:name="Times New Roman" svg:font-family="&apos;Times New Roman&apos;" style:font-family-generic="roman" style:font-pitch="variable"/>]])
    return content
  end
}

Make:match("styles.4oy$", process)

It can be executed using

 make4ht -e buildfilename.mk4 -c configfile.cfg -f odt filename.tex

The styles.4oy$ file pattern matches file with ooffice styles and executes the filter which declares "Times New Roman" font to be used in the document.

Edit:

The Times New Roman is not used in the document because it is not declared. To declare new fonts, it is necessary to modify the styles.xml file. unfortunately, interface for this declaration is not provided by tex4ht, so we must use a trick involving mk4 build file:

local mkutils = require "mkutils"
local zip = require "zip"

settings_add {
  tex4ht_sty_par = ",ooffice",
  tex4ht_par =  " ooffice/! -cmozhtf",
  t4ht_par =  " -cooxtpipes -coo "
}


Make:match("tmp$", function(name, par)
  local odtname = mkutils.remove_extension(name) .. ".odt"
  local stylesname = "styles.xml"
  local odtfile = zip.open(odtname)
  local styles = odtfile:open("styles.xml")
  local content = styles:read("*all")
  styles:close()
  odtfile:close()
  content = content:gsub("<office:font%-face%-decls>", [[<office:font-face-decls>
  <style:font-face style:name="Times New Roman" svg:font-family="&apos;Times New Roman&apos;" style:font-family-generic="roman" style:font-pitch="variable"/>]])
  print(content)
  local styles_file  = io.open(stylesname,"w")
  styles_file:write(content)
  styles_file:close()
  os.execute("zip " .. odtname .. " " .. stylesname)
  os.remove(stylesname)
end)

Use it as

make4ht -e buildfilename.mk4 -c configfile.cfg filename.tex

in TL 2018, it will be possible to create odt files directly using make4ht with make4ht -f odt. because it is not readily available, the settings for the odt output need to be set explicitly.

In the Make:match function, the settings.xml is extracted from the odt file and updated with declarations for Times New Roman.
