[NTG-context] Checking for a Unicode prefix of a Unicode string
I wasn't aware of a general-purpose "doifstartswith" macro in ConTeXt (the \doifnextcharelse macro only works one character at a time, and the \doifinstring macros may capture substrings that are not prefixes), and I'd like to develop one for something I'm working on. I've been trying to do this in Lua, as that seemed like the most natural approach. Normally, something like this would work fine as a foundation: ``` function isprefix(prefix, str) if string.sub(str, 1, string.len(prefix)) == prefix then return true end return false end ``` Unfortunately, if I want to check for prefixes that include two-byte characters like § and ¶, then the positions and string lengths that I specify no longer correspond to the actual byte offsets and lengths that Lua uses. I'm aware of the utf8 plugin that was intended to address this issue, but the following code also isn't working: ``` function sbl.isprefix(prefix, str) -- lua is devious and measures string length in bytes, not chars, -- so we can't just use string.sub and string.len as we normally would. local i = utf8.offset(str, 1) local j = utf8.offset(str, utf8.len(prefix) + 1) - 1 if string.sub(str, i, j) == prefix then return true end return false end ``` The only other detail that may be relevant is that I'm passing a macro as the "str" input. But this should be expanded when the Lua code is manipulating it, right? I'm sure there's something obvious that I'm doing wrong, but I've been trying to get this to work for at least a couple hours now, and I don't know what else to try. If there is a simple fix to my Lua code or an existing ConTeXt macro that will get the job done, I'd appreciate it!

technically there can be many so called sectionblocks in any order and
as one is chosen and no previous one has been set, all preceding sec

this is needed to get things like bookmarks right
so ... when you use sectionblocks used them consistently i.e. use
bodymatter wrapping for the preceding sections

Re: [NTG-context] Automatic counting groupsuffix for subfigures

Hi!
I'd like to use subfigure numbering for floats. This works:
\useMPlibrary [dum]

See \in{image}[ref:right] (right) and \in{image}[ref:left] (left).
\stoptext
The output is correct, but the usage is verbose. I'd like to replace
the manual groupsuffix numbering with something automatic. ConTeXt
uses automatic numbering in many places so it seems strange to
number the subfigures manually.
I have tried using counters and labels, but something is always
messed up and I couldn't get it to work.
How to achieve automatic subfigure numbering without specifying the
groupsuffix manually?
sort of tricky due to multipass and other synchronizations although in
the end some 20 lines of code can do it ... i'll send you and wolfgang a
test file with a more native feature

Re: [NTG-context] adjusting vertical space
That was the clue I needed - in particular the use of minus values,
which I had entirely overlooked. And since \vskip works, so, therefore,
does simple \blank with a minus value (and better style!), and for that
matter also \hskip to make micro horizontal adjustments. In the end, so
simple and another lesson learned - look to the simple rather than the
more complicated solutions first.
Thank you for the patient mentoring.
