How to make ebook-convert use multi-line mode regexp?
I want to use ^ and $ in regular expressions in ebook-convert, but it apparently doesn't operate in multi-line mode.
$ cat > sample.txt abc def ghi <ctrl-d> $ ebook-convert.exe sample.txt sample2.txt --sr1-search "abc" --sr1-replace 'zzz' Conversion options changed from defaults: sr1_replace: u'zzz' sr1_search: u'abc' 1% Converting input to HTML... InputFormatPlugin: TXT Input running on Z:\data\text\sci\physics\thermodynamics\sample.txt Language not specified Creator not specified Building file list... Normalizing filename cases Rewriting HTML links flow is too short, not running heuristics Forcing index.html into XHTML namespace 34% Running transforms on e-book... Merging user specified metadata... Detecting structure... Auto generated TOC with 0 entries. Flattening CSS and remapping font sizes... Source base font size is 12.00000pt Removing fake margins... Cleaning up manifest... Trimming unused files from manifest... Creating TXT Output... 67% Running TXT Output plugin Converting XHTML to TXT... TXT output written to Z:\scratch\sample2.txt Output saved to Z:\scratch\sample2.txt $ cat sample2.txt zzz def ghi $ ebook-convert.exe sample.txt sample2.txt --sr1-search "^abc" --sr1-replace 'zzz' Conversion options changed from defaults: sr1_replace: u'zzz' sr1_search: u'^abc' 1% Converting input to HTML... InputFormatPlugin: TXT Input running on Z:\data\text\sci\physics\thermodynamics\sample.txt Language not specified Creator not specified Building file list...

Where does the ?m go?
$ ebook-convert.exe sample.txt sample2.txt --sr1-search '?m^abc' --sr1-replace 'zzz' ... $ cat sample2.txt =~ abc def (It actually puts the =~ into the output, which makes me suspect the program is somehow dropping a bit of its own pattern-matching source code into the output. This is win64 version 3.21 on Windows 7; I just updated it this morning.) I figured out how to do what I need to do without multi-line mode, so I don't need an answer right now. But this =~ might be a bug. Last edited by Shagbark; 04-11-2018 at 03:33 PM. |

You are missing the parentheses and this is all documented in the manual https://manual.calibre-ebook.com/reg...reference.html
