It all depends on how serious an issue is. For instance, columns use a
new mechanism so it might be as simple as changing some defaults.

Well, there aren't *so many* issues. If the columns are fine with you,
they are fine with me too. Changing the references is not a problem.
(Well, if they keep changing every week, well, that could be a problem
for the well-being of the test suite).

Mixed columns probably need some time to become stable (and the width /
distance should definitely be compatible).

Some things, like the chemical stuff, require someone who actually does
know what they are (I don't).

Alan is currently reviewing the chemical subsystem.

The whole point of having a test suite is to catch the regressions
before they pile up. I just reported everything I saw.

Sure. In principle we should be downard compatible (although mkiv might
do things better than mkii) and at some point things should stabelize
again. So, any indication if a substantial change is important.

Thanks for the fix! Now another thing I noticed is that the text
style “capital” fails with highlights:

·
\definehead [testhead] [section] [style=capital] %% -> works
\definehighlight [testhighlight] [style=capital] %% -> not always

\starttext
\testhead{woody words}%% -> works
gorn {\testhighlight ocelot} wasp %% -> works
gorn \testhighlight{ocelot}  wasp %% -> fails
\stoptext
·

“Capital”, “WORD” etc. don’t have the problem, and in other
circumstances, “capital” seems to work as expected. This is also
a regression since TL2012.

That's why I use a header for each test file. You can specify
“sensitivity=low|medium|high”, this sets a predefined tolerance for
the page difference. I don't see any other option. There is no

not to always mark a fifty page document as “failed”.


I'm not sure that exists a “fuzzy” algorithm for the tolerance. From my

generate a lot of noise, because each glyph will be “doubled”. I'm
generating, with the visual diffs, a script to launch two PDF viewers and
eventually promote the generated to the new reference.

I guess there is no shortcuts to the manual ispection of the diffs.

I removed that part, it was a stupid idea. At the moment it's a pure
Lua solution. It's divided into two parts. The first part is the
database update, Lua runs context on the tests and writes the
results to a database (a Lua table stored in a file). For the second
part context is run on the database to generate the report from the
database. With this database you can display information like “What
broke in the last beta”.

I think I'll have to run some benchmark to see if it can save some
resources and speed up the testing. I don't care too much for the mkiv
integration. The other Marco's idea was exactly to make conTeXt run the
tests. I prefer to let ConTeXt do the typesetting and do the dirty stuff
with perl.

So far I've included the testfiles from contexttest, parking the failing
ones in a dedicated directory. There are 62 files now, and the test
takes 13 minutes to run on my humble machine.

It's not a huge difference, but it can integrated better with mkiv; see

(if you like these kind of things)

So far I've used imagemagick. I guess that it shouldn't be a problem to
replace it with its fork, if it offers the same features. I've never
used graphicsmagick. Can we expect better performances?

Dear Proch?zka Luk?? Ing and Hans,

Thank you for the reply.

It works fine.

I modify your code to write a matrix and it also works too.

\startformula
\startluacode
local NC, NR = context.NC, context.NR
local t = {{1,0,3,4},{0,2,-2,5},{0,0,1,2}}
context.startmatrix() --"{left={\left (\,},right={\,\right)}}")
for _, r in ipairs(t) do
for _, c in ipairs(r) do
NC()
context(c)
end
NR()
end
context.stopmatrix()
\stopluacode
\stopformula

But I couldn't put "( )" before and after matrix.
If I use
context.startmatrix("{left={\left (\,},right={\,\right)}}")
then it wrote "left…" as text before the matrix.

How to enclose matrix with (  )?


... See the new sample attached.


printMatrix = function(tab)
  context.startmatrix{left = "\\left(\\,", right = "\\,\\right)"}
for _, r in ipairs(tab) do
  for _, c in ipairs(r) do
context.NC(c)
  end
  context.NR()
end
  context.stopmatrix()
end

context.startmatrix{left="\\left(\\,",right="\\,\\right)"}

I cleaned up the code and rewrote some part of it. But it's in a
stage where it does not compile. At the moment I'm quite busy and
don't have time to work on that, that's why I didn't publish, yet.
