Beside \textdimension(true|false) there is \spaceddimensions(true|false) to add a small space between dimension.

The units module has unlike many other commands and environments in context not many parameters to change the layout and it will make more sense to write another module for units which has these options than modifying the existing one.

With MkIV we have a powerful tool to do this because Lua make it so easy to parse and format numbers and units, see here: http://bitbucket.org/wolfs/units/src/tip/files/

I actually have a mkiv variant somewhere and will pick up that thread soon.

Is the new module with the old syntax (10 \Meter etc.) or a new one.

first I'm redoing digits with regards to the units themselves, we can do both: \Meter \Per \Second and m/s) .. i'm still considering doing it at the node end .. typical dark winternight work with a movie/talkshow on tv in the background Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

To add a bit to this thread: just checked the siunits module, it's awesome. Spacing is right, sans font units work out of the box, no need for \ after the units and syntax for adding new units is very simple. I have a couple of questions: 1. How to change decimal separator and thousand separator? 2. Should'nt \siunit[thousandgroup=4]{10000} produce 10000 instead of 1.0000 to be consistent with default thousandgroup=3? 3. \ss $\siunit{\square\kilo\meter}$ will produce all roman, but square will be sans. Why? -- Vedran Miletić

Will siunits module be used as a base for this or will this be something completely new?

I don't know what you mean with siunits. Wolfgangs module? We have unit support in context for along time (also as part of some mathml extensions). So, we're more talking of an upgrade of the current module (units and digits) and I will have a look at Wolfgangs code to see what additional support is in there and we can merge things if needed. The fundamentals of units are not going to change much, apart from the fact that we can now parse m/s if needed instead of using the verbose names). Keep in mind that the units module runs on top of synonyms so that one can ask for lists of used units and meanings of them. Anyhow, Wolfgang and I will look into it when we have time (and energy) so eventually something upgraded will show up.

- si{kg.m/s^2} - si{\kilo\gram\metre\per\square\second}

My two bits, for what it is worth... I have never liked the \kilo\gram\meter\per\square\second particularly as we now have utf8 input. To be most readable, kg.m/s² is far superior. (and to be digestable by non-TeX users, as yes, I do often share my document source with collegues who do not use TeX, and they even often edit them using MS-Word, for example, as a text editor) I should use some sort of units module, as writing, as I do, 0{,}2\,nm$^2$ is pretty ugly!

He’s talking about my module. The difference between our modules is that your use “10 \Meter \Per \Second” for the input while i use ”\siunit{10\meter\per\second}”.

ah, so you explicitly tag the unit one reason why I didn't do this is that it does not integrate well in math at that time (superscripts etc) and the mechanism was mainly meant for schoolbooks (and strongly related to mathml input as well)

There is nothing wrong about two modules with the same function as long as both do not cause a problem for the module (and i took care of this in my module).

sure

Parts like the number parsing can become part of the core and you provide a function which others can use to integrate it in their own macros.

indeed

hm, never seen that one (no time to look into it anyway)

- si{kg.m/s^2} - si{\kilo\gram\metre\per\square\second}

we can provide the first one flagged as "unit mode for dummies" but it will never work out well with $ a = 123 m/s^2$ so one would always hae to tag the unit then.

Keep in mind that the units module runs on top of synonyms so that one can ask for lists of used units and meanings of them.

Adding this function is no problem, synonyms can also be integrated in any other system.

yes let's discuss it at the conference Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
