ptxprint-mods.tex not getting applied?

Question

Some more weirdness... We are trying to get \q2's to stay with the preceding \q1's (see https://support.bible/13086/get-q2-to-stay-with-the-previous-q1), and are having good luck with this command in our test projects:

\sethook{before}{q2}{\nobreak}

But in our real project, the command is not getting applied. I thought maybe the ptxprint-mods.tex file wasn't getting loaded, but we have \qs (Selah) processing in that file as well, and when that is commented out, the Selah processing goes away in the output. I've been poking through the .tex file and the XeTeX Log, and do see:

Reading optional file "../../../shared/ptxprint/PSA_1_a_72/ptxprint-mods.tex"
 (../../../shared/ptxprint/PSA_1_a_72/ptxprint-mods.tex) 

which confirms that.

So the .tex file is getting processed, but we still have dangling \q2's at the top of pages.

What else might be the problem?

Answer 1

我首先猜測，檔案後方可能還有另一個 \sethook{before}{q2}{}。
與某些會額外新增指令的機制不同，\sethook、\setbookhook、setbetweenhook 等指令會取代同一掛鉤點（hook point）先前定義的內容。
這有點棘手，但你可以透過包含一個必定會導致程序崩潰的內容來檢查掛鉤是否被觸發（或 .tex 檔案是否被讀取），例如 \errormessage{Q2 HOOK}。
這樣你就能在崩潰報告中看到該訊息（以及崩潰前發生的事情）。

如果你設定的掛鉤確實被激活了，但你仍然看到該處發生分頁，那麼可能是有其他內容增加了額外的間距，從而允許了分頁（這需要仔細檢查 .tex 檔案中的其他內容，或進行樣式檢查）。
