Summary0015584: [patch] Warn when a hyphenation dictionary is missing
DescriptionI had two documents, both in English, and Scribus was hyphenating one but not the other.
I put in debug code, and apparently one document was British English and the other was US English.
Scribus found the British English hyphenation dictionary hyph_en_GB.dic in its resources, but it didn't have a corresponding US English hyphenation dictionary.
I have Fedora 28 x86_64 Linux, and I installed the 'hyphen-en' package, which created /usr/share/hyphen/hyph_en_US.dic, and then Scribus found it and hyphenated my document.
The Fedora/RedHat/CentOS notes for Scribus should probably mention installing the hyphen-en package.
The hyphen-en package creates a lot of symbolic links in /usr/share/hyphen that all point to hyph_en_US.dic, so maybe Scribus can use its en_GB dictionary for other English regions as well.
I have attached a patch to hyphenator.cpp that shows a warning on the first attempt to reference a missing hyphenation dictionary.
Probably LanguageManager should have a flag for languages that are ok without hyphenation dictionaries so this warning does not get annoying.
I have Scribus 1.5.5.svn that I built from source. The product version pull down in mantis only goes up to 1.5.4.svn.
TagsNo tags attached.

a/ i've updated the version... 1.5.5svn is available : - )

b/ i upload a diff so that the patch can be seen by expanding it in mantis

c/ i like the idea of warning the user when the hyphenation does not happen because of a missing dictionary... the patch is very simple, but i don't really like that a pop is shown the first time it's used.

d/ i wonder if this should not go into the preflight verifier...

e/ ... and/or below the language select box in the PP

what do you think?

I think that the language selection box is better than the preflight verifier because if you are trying to figure out why a document isn't hyphenating, you might think to double-check the language, but you might not try the preflight verifier until immediately before trying to produce a PDF. Also, each page can have multiple text frames; each text frame can have text with multiple styles; each style can have a different language, so the preflight verifier could potentially show a large number of warnings.

it's possible that both are needed.
(as an example for the case that you get a file from somebody who had the hyphenation, you edit and then produce a pdf)

for the number of warnings:
- you're right
- you can turn off warnings in the settings
- i think that if you pick a language you should have its hyphenation installed
- (what to do for languages that do not have (yet) an hyphenation?)
