Does the whole book need to be error free before I can print one chapter?

Question

I wanted to try printing one chapter.  I ran the Basic Checks and corrected the errors in chapter 1 but when I went to print it I got the following error...

Failed due to an error in the USFM file.

Run the Basic Checks in Paratext and try again.

<class 'SyntaxError'>: Cannot parse .

Answer 1

Traditionally PTXprint has been able to print almost anything you throw at it. But as we have recently added interactive PDFs which require a greater level of 'control' over the text, I am guessing it is tripping up on structural USFM issues later in the file. You could work around this problem by just adding a changes.txt rule like this, for example, to throw away everything after (and including) chapter 2 of MRK, which would leave you with the contents of just chapter 1:  (replace MRK with the right book and chapter as needed)

at MRK "(?s)\\c 2\s.+" >  ""

If for some reason, you still get the same error even with this change, then try placing this additional line before the rule:

sections("initial")
at MRK "(?s)\\c 2\s.+" >  ""

If you still get an error after that, it indicates that there is some other error (not necessarily a USFM issue) within chapter 1.
