I would like to create a book (to be exact a psalter). Basically it is a database issue. I have on one hand a tex document (to be exact currently it's still a word document) with all the psalms and on the other the book I want where I want to insert selected psalm from the first document. I don't know how to start to keep it simple. I look to datatool but can a psalm be an entry ? Or Should a create a document for each psalm that will be called ? If yes, how can I do it quickly ? Can I call the psalm base on its title in the document containing all the psalm ?

  • It's unclear why you would need a database for this, unless you envision changing the order of the included psalms on demand, or including only some and not others. But even then, I don't think you need a database. Surely this is no different that any other large-ish document, where it makes sense to have each psalm as a separate file and then a master document that simply uses \include or \input to input them.

  • Of course you could make the master document simpler by naming each psalm file psalm-x.tex and then use a loop over x, but this is really a matter of whether you want a 3 line master document or a 150 line master document. If you do need mix and match versions, then just keep a database of the filenames and use datatool or similar processing to do the different versions.

  • Thanks @AlanMunn yes I would like to change the order of the included psalms on demand etc. I was thinking about \include or \input but that mean I need to create a a document for each psalm that is to say 150 documents... Is there an easy way to create those documents ?

  • Since your source is in Word, it's probably fastest to simply cut and paste each into a new .tex document. This is something you do only once. xkcd.com/1205 Since you're converting from Word, I would recommend using a unicode engine like XeLaTeX or LuaLaTeX. But I suspect there may be more issues lurking in the conversion than in the creating 150 files.

  • There’s one of these for a different set of scriptures. You might look at its source.

A database can contain whatever you want as data associated to a key. Even a longish text. Just need a database (-style package, you presumably just have a single key --psalm number/name-- and associated data --text--) package to handles that.

The Linux (BSD original, some work on porting to other platforms) strfile(1) utility (part of fortune-mod here) takes files made of paragraphs and creates a file indexed with the paragraphs for random access, you'd need to hack it to add a key. It could give some inspiration.

Or kludge up a script in some scripting language that reads text with some marker like %% identifier lines, and reads a file containing something like:

identifier1
Lorem ispum dolor sit amet, ...
%
identifier2
Sed ut perspiciatis unde omnis iste natus error sit...

looks up the identifier and replaces by the following text.

  • I haven't try yet but according to datatool user guide, we cannot have paragraph break (and maybe no other command...)

I have found a solution to call the psalm I need from a master file composed of all the palms. So, in a .tex file, I have the "database" containing all the psalms. Each psalm is within a command which serve as a identifier. Here is an example:

\newcommand{\PsalmI}{%
Lorem ipsum...
}
\newcommand{\PsalmII}{%
Sed ut perspiciatis unde omnis iste natus error sit...
}

In order to call the psalm, I need to call the macro \PsalmI for example. However, as the psalm I called based on the content of another databased, I have created another command \Psalmus which name depends on the variable:

\newcommand{\Psalmus}[1]{\csname Psalm#1\endcsname}

To call the psalm, I just need to call it through the macro: \Psalmus{II} for example. This calls the macro \PsalmII and displays the second psalm.

This solution is based on Ulrike Fischer's solution to this topic.
