[Po4a-devel] Markup text alignment interoperability problem between versions 0.42 and 0.45 (debian)

Hi, First of all, can you please CC me as I'm not subscribed to your mailing list? My name is Carlos Zuferri and I contribute to the debian project translating documentation. I mainly translate the contents of live-manual, so the information below refers to it. live-manual uses a markup language that is very similar to markdown. For example for monospace #{text}#, for bold *{text}* and other similar features. I do not know if I have stated the title of this message correctly. With "alignment" I mean "text justification". Let's see if I can explain the situation correctly. (The operating system is debian.) Debian wheezy includes po4a version 0.42-1 Debian jessie/sid include po4a version 0.45-1 Version 0.45 aligns marked up text like this: I copy and paste an original string from a .po file (taken from the Polish translation): "_* Zmienne dotyczące parametrów startowych live-config zaczynają się od #" "{LIVE_}#." Now I copy and paste the same string after processing it with po4a 0.45: "_* Zmienne dotyczące parametrów startowych live-config zaczynają się od " "#{LIVE_}#." This "alignment" thing changes hundreds and hundreds of strings in dozens of .po files. Even though at first I thought that this was a bug, I finally accepted the fact that it could be a very nice feature since it really does improve readability. But then the problems begin. If a translator uses po4a version 0.45 and pushes all the changed strings in the .po files to git and anonther translator using po4a 0.42 pulls, and then makes changes, the alignment is reverted and so all the strings and po files go back to the original state. I copy and paste the same strings as above after processing them with 0.42: -"_* Zmienne dotyczące parametrów startowych live-config zaczynają się od " -"#{LIVE_}#." +"_* Zmienne dotyczące parametrów startowych live-config zaczynają się od #" +"{LIVE_}#." So as you can see it is a catch 22 situation in the sense that strings are modified once and again meaninlessly. I really do not know if this is just a problem of text justification (in terms of line length) or that po4a has a certain algorithm that makes it act this way. Maybe it has to do with the upstream gnu gettext. By the way, I forgot to say that the same thing happens in another case, and this time it is not a markup feature. In live-manual there is one instance of the word "files" written as "file(s)" this word is also aligned. So far we have worked around this issue by mainly using just wheezy and being very careful what to commit to git and what not, but there is one translator that is using the jessie/sid version and pushing "everything" a bit carelessly, causing the problem mentioned above. Is there anything that we can do (configuration wise) to avoid this? Sorry for the long e-mail. I hope I have been able to explain the problem correctly. To finish with, let me post some links to the git repo in case someone fancies to take a look at it: http://live.debian.net/gitweb/?p=live-manual.git;a=shortlog;h=refs/heads/... The po4a related makefile: http://live.debian.net/gitweb/?p=live-manual.git;a=blob;f=manual/Makefile... And in more detail, the diff of the example I have used in this email: http://live.debian.net/gitweb/?p=live-manual.git;a=commitdiff;h=0d4dd2bac...
