Scribus having trouble with gabc headers in 5.2.1

[domoknight]

The score is rendering in Scribus, but the gabc headers appear to be ignored.

Using the sample gabc:

name: myscore; mode: 6; commentary: howdy; %% (c3) Pó(eh/hi)pu(h)lus(h) Si(hi)on,(hgh.)

No mode number is shown. Also, even though I'm using \gresetheadercapture{commentary}{grecommentary[3mm]}{string} no commentary is printed.

An excerpt from the logfile is as follows:

Module gregoriotex Info: capturing header commentary using grecommentary[3mm], s
tring=true, name=nil on input line 24
Module gregoriotex Info: scribus_file-score.gabc has been modified and scribus_f

on input line 25

This appears to be related to the rewrite of the Scribus tool (900_gregorio.xml). Somewhere along the way, the gabc header info is not getting passed along. If I use the 900_gregorio.xml file from the 5.1.1 build, the header data passes through just fine. (annotation text appears and gresetheadercapture works)

Thanks for the info. I’ll have to look into that, but it may not be until after Easter.

I've had a chance to do some additional investigation, and the problem appears to be the use of the filecontents environment. This environment adds a comment header which uses %% to mark itself and therefore fouls up the executable's ability to detect the proper header (we use %% to mark the transition from headers to score). The correct environment to use is filecontents* which doesn't add the comment header. However, I haven't had the chance to fully test this because of other problems I'm having with my installation. If someone else can test and verify the diagnosis, then I'll put up the PR with a fix. Otherwise this will have to wait until I fully sort out the problem with my system.

[domoknight]

Does testing this involve changing the call to filecontents in the 900 file like this?

    \begin{filecontents*}{scribus_file-score.gabc}
</preamble>
<postamble>
    \end{filecontents*}

[rpspringuel]

Exactly.

[domoknight]

That appears to fix what gets written in the generated *.gabc file, but seems to break other things. See log excerpt below:

[rpspringuel]

Can you go into the temporary directory that Scribus is creating and copy out the generated scribus_file-score.gabc and post that here for me to look at?

[domoknight]

Here is the .gabc and the .gtex scribus_file-score.zip

[rpspringuel]

Okay, those errors appear to be caused by the introduction of whitespace before name: in the gabc file. I think we have to wreck the indentation of the <preamble> block in 900_gregorio.xml to fix that. It'll make the file harder for a human to read, but what's that compared to making it work?

Let's try the least destructive method first: take lines 51 and 52 and combine them so that line 51 now reads like this:

        \begin{filecontents*}{scribus_file-score.gabc}</preamble>

[domoknight]

Things are still a bit busted. Here's a cat of the log:

Okay, it seems that there must be a line ending after \begin{filecontents*}{<file-name>}.

So, try having lines 51 and 52 read this way:

        \begin{filecontents*}{scribus_file-score.gabc}
</preamble>

I also note a warning about the last line scribus_file-score.gabc in that log, so make line 54 read:

\end{filecontents*}

(i.e. delete all the spaces at the beginning of the line.)

[domoknight]

Success!

Lines 51-54:

        \begin{filecontents*}{scribus_file-score.gabc}
</preamble>
<postamble>
\end{filecontents*}

[rpspringuel]

Excellent. I'll work up the PR now.

[domoknight]

Does the "nonstopmode" mentioned on line 25 force all the render panes in a single Scribus file to use the same gregorio options? I ask because this fix may have exposed something else for a new thread...

[rpspringuel]

nonstopmode simply means that LuaTeX should continue to try and create the pdf if it encounters an error instead of halting and waiting for user input (which, in some cases, can correct the error). This is to prevent the rendering tool from hanging, waiting for input that the user is unable to provide given the interface available. It should not affect the way that Scribus sets and makes use of the various options in the tool.
