MetaObj with labels in built-in objects (MetaObj Standard Library)
by Stefan Müller 20 Sep '11

20 Sep '11

Hi list, some time ago I posted on this list about problems with MetaObj in ConTeXt when using labels. There's a wiki article about this now [1]. Just recently I was forced to notice that this solution does not work when the label to be drawn is part of the object definition. So the example from [1] works fine with the added boolean flag, but the following example (which means basically all built-in MetaObj objects with text) does not. It compiles well but there is no text. --8<--------------------start--------------------8<-- \startMPinclusions[+] input metaobj; boolean firstrun; firstrun := true; \stopMPinclusions \startMPpage if firstrun: newBox.a(\sometxt{Text}); a.c = origin; fi; drawObj(a); firstrun := false; \stopMPpage -->8--------------------stop-------------------->8-- I'm out of ideas how to fix this. I tried putting the text into a separate pictrue variable and use this in "newBox". In addition, I thought it should be possible to modify metaobj.mp to check for a boolean variable (e.g. "firstrun") and let the macros there react to its value accordingly , but I always got either no text or errors. I can draw the picture I wanted to get in the first place with plain MetaFun, but I thought MetaObj would be even more "fun". Now I'm very curious if someone on this list can come up with something. I think it would be great if MetaObj could be fully used within ConTeXt. Thanks in advance for taking the time to think about this and any hints! Kind regards, Stefan.

Long word out of text area/No proper line wrap with flushleft
by Stefan Müller 20 Sep '11

20 Sep '11

Hi again, in one of my documents I want the text to be flushedleft and not hyphenated, see the following example. \setupalign[flushleft, nothyphenated] \starttext \showlayout bbbbbbbbbb bbbbbbbbbb bbbbbbbbbb bbbbbbbbbb bbbbbbbbbb aaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbbbb \stoptext However, in this example the aaa...a-"word" is not moved to the next line but written partially into the margin instead. I understand this behaviour for right-left-aligned text to avoid extremely stretched-out spaces, but here it doesn't seem right to me. Can I change this behaviour somehow? Thanks for any advice! Best regards, Stefan

Double interline spacing with headings
by Stefan Müller 20 Sep '11

20 Sep '11

Hi list, I want to have double line spacing in my document setup, including the headings. But in the following example, the space before the heading is slightly different from the interline spacing between the other lines. How to do this right? (standalone MkIV 2011.09.20 00:09) \setuphead[section][style=normal, interlinespace=big, before=, after=] \starttext \setupinterlinespace[big] \input ward \section{\input ward} \input ward \stoptext TIA for your help! Kind regards, Stefan

crop PDF pages
by Yue Wang 20 Sep '11

20 Sep '11

Hi, powerful context users: I'm wondering why there is no crop setting for \externalfigure or \insertpages. I have a lot of scanned books in PDF format, most of them are double sided. I want to read them on kindle but the huge margins take too much space and as a result the texts are too small. I want to use commands like \insertpages to crop all the pages with different bounding box settings for odd/even pages. there's a "scale" option for \copypages but it's somewhat naive to use in such practical cases...

Hey folks, How do I ensure that when a sentence has more than one footnote at the same place, that those numbers above the sentence are separated with a comma? -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

metafun shared code
by Marcin Borkowski 19 Sep '11

19 Sep '11

Hi all, I'd like to have some MP code shared between unique graphics (in MkIV). One example: I'd like to have drawoptions <something> for all graphics. Another one: I'd like to have two similar (but different) unique graphics, and I'd like them to share some code. How to do these two things? Best -- Marcin Borkowski http://mbork.pl

Disabling specific ligatures
by Aditya Mahajan 19 Sep '11

19 Sep '11

In MkII, one can disable ligatures by inserting {} at the appropriate place. For example `self{}ish` disables the ligature between f and i. What is the equivalent way to disable ligatures in MkIV? Thanks, Aditya

sizing MPpage
by Meer, H. van der 19 Sep '11

How can one set the size of a \startMPpage..\stopMPpage generated picture. For example forcing its dimensions to 5X4cm. Or better still, derived from variables in the code. Hans van der Meer
