Controlling text justification in preamble

[konradzdeb]

Expected Behavior

• Possible to define whether the text should be left/right justified using a quick switch
• Possibile to stretch tex to the full length of the top and bottom line

Actual Behavior

Arbintary justification

Steps to reproduce the behavior

Insert longer text in the preamble

> This is longer text that should be justified and, possibly streatched a little  This is longer text that should be justified and, possibly streatched a little This is longer text that should be justified and, possibly streatched a little bla bla bla

Thanks for the bug report -- It is certainly possible to work around this by customising the context template, but it's nontrivial in pure markdown, and therefore should probably be out of scope for this project.

Hi, thanks for replying. It's a good project and very useful. I'll try to have a look and see if I can come up with a PR but that won't be soon

So I had a (very) quick look into the for the styles tex, for quick fix the one could just modify the setupalign call with the right switch, which seems to do the job (353ad13c6bf90cb94107f4f8b638f79773861da3)

% Controles elements relevant for preamble
% List of options for setupalign:
% normal *or* width *or* yes    justified alignment
% middle    centered lines
% flushleft *or* no *or* right  left-aligned (The right is from 'ragged-right'. Don't use it.)
% flushright *or* left  right-aligned (Again, better to not use left.)
% inner Flush to inner margin.
% outer Flush to outer margin.
% disable   Used only for oneliners. Equivalent to flushleft, but something called \parfillskip is set to zero.
% last  Justified, with last line centered.
