Didn't know about that, thanks.

However, this still continues processing the document and produces a PDF

zero status code, which is fairly easy to ignore if you're not paying
attention.


If someone doesn't pay that kind of attention one can wonder about the 
quality of the document.



Is there a way to make this produce a nice little "error" PDF as soon as
the error occurs just like using "\undefined" does?


Only If I add it as option (directive driven, must find some good name 
for it).


Most modules add commands and that shows immediately. Modules that kick 
in without some command that needs to enable something are sort of 
not-done or rare and experimental only and comparable to when some 
module patches or overloads core functionality withoutr mentioning it.


Also, keep in mind that styles can also be modules and that normally 
shows in ta different output.



and if needed can add that line to a local cont-loc.mkxl file so that it
always kicks in.


Didn't know about that either.


Ah, that's one of the oldest features: cont-new (for patched before 
updates), cont-loc (for local preferences) and cont-exp (for wolfgang 
and me)



But wouldn't it make sense for this to be an error by default? Nothing
good can happen if a user loads a non-existent (or misspelled) module.
Loading a non-existent file is a fatal error even in Plain TeX
\nonstopmode. I think that making this an error by default would break
very few working documents. In exchange, most users would get much more
helpful error messages.
It would never be default because it is quite possible to have cases 
where a module became redundant or is optional. There arte very few 
cases where we are not downward 'command and file' compatible (the most 
noticeable exceptions are when font, language and encoding subsystems 
fundamentally change).

Re: [NTG-context] String substitution using regular expressions and backreferences

[Thangalin via ntg-context]

I've attempted to apply Wolfgang's subtle suggestion of using Lua to parse
the input document using a regular expression via lpeg.replacer. The
replacement itself works fine; however, in doing so the XML document
structure is converted to text, which means that it is no longer possible
to "flush" the XML for further processing as XML. The result is that any
unresolved XML tags are written verbatim to the PDF:

https://i.stack.imgur.com/9ZFND.png

There are two other issues with this approach. First is efficiency. Second
is that the processing function would have to be called for every XML
element to capture the replacement.

My original post asked about applying regex word substitution in a ConTeXt
way, such as:

\definereplacement[SubstMac][ match={Mc([A-Z].*)}, replace={\Mac \\1} ]
\definereplacement[SubstPostmeridian][ match={[Pp]\\.[Mm]\\.},
replace={\cap{pm}} ]

That seems like the cleanest approach because it would work on top of XML
or any other source document. Nevertheless, here is what I tried, which
partially works:

\startbuffer[main]

  “Mr. McAnulty, I presume?”
  Regular text. Irregular text.
\stopbuffer
\startxmlsetups xml:xhtml
  \xmlsetsetup{\xmldocument}{*}{-}
  \xmlsetsetup{\xmldocument}{html|p|em}{xml:*}\stopxmlsetups
\startxmlsetups xml:html
  \startdocument
\xmlflush{#1}
  \stopdocument\stopxmlsetups
% Paragraphs are followed by a paragraph break, but only if not
nested.\startxmlsetups xml:p
  \xmlfunction{#1}{p}
  \par\stopxmlsetups
\startxmlsetups xml:em
  \dontleavehmode{\em\xmlflush{#1}}\stopxmlsetups
\startluacode
function xml.functions.p( t )
  rep = { [1] = { "McAnulty", "\\Mac Anulty" } }
  x = lpeg.replacer( rep ):match( tostring( xml.text( t ) ) )

  buffers.assign( "p", context( x ) )
  context.getbuffer{ "p" }
end\stopluacode
\xmlregistersetup{xml:xhtml}
\def\Mac{%
  % Determine the sizes of 'M' and 'c'.
  \newbox\MacMBox%
  \setbox\MacMBox\hbox{M}%
  \newbox\MacCBox%
  \setbox\MacCBox\hbox{c}%
  %
  % Cheat to dynamically derive the kerning size by putting Mc in a box.
  %
  \newbox\MacKernBox%
  \setbox\MacKernBox\hbox{\inframed[offset=\zeropoint, width=fit]{Mc}}%
  \def\MacDelta{\dimexpr\wd\MacKernBox-\wd\MacMBox-\wd\MacCBox\relax}%
  \def\MacUWidth{\dimexpr\wd\MacCBox-.75\MacDelta\relax}%
  \def\MacRule{\vrule width \MacUWidth height .04em depth \zeropoint \relax}%
  \def\MacKern{\dimexpr\wd\MacKernBox-\wd\MacMBox-\wd\MacCBox\relax}%
  \def\MacHeight{\dimexpr\ht\MacMBox-\ht\MacCBox\relax}%
  %
  % Write Mc, where c has a macron, to the document.
  %
  M{%
\dontleavehmode{\raisebox{\MacHeight}\hbox{c}}%
\kern-1.04\MacUWidth
\MacRule
\kern.08\MacUWidth
  }%
}%
\xmlprocessbuffer{main}{main}{}

As shown in the screen shot, this doesn't correctly handle nested XML
elements.

Any ideas on what approach to take to perform a string replacement in
ConTeXt?

Thanks again!

you use a function but headertexts are not frozen which meand that you

context.setupheadertexts(
{
function()

the "return true" makes sure that the function stays around

I don’t know how ConTeXt handles it internally, but placement to main
character differs with each letter:

\starttext
  \doloopoverlist{\tf,\ss,\tt}
{\bgroup\recursestring\doloopoverlist{\tf,\it,\bf,\bi,\sc}
  {\bgroup\recursestring\dorecurse{26}
{\character{\recurselevel}̱ }\par}\egroup}
\stoptext

just run the attached


Many thanks, it works fine.

the one in the update is more interesting

[NTG-context] new uplaod

[Hans Hagen via ntg-context]

Hi,

I uploaded a new lmtx. Again some updated math of which details will be 
revealed later. Apart from some details we added suport for fourier 
notations. There are no high level definitions yet as we have to invent 
names but this is how it works (private unicode slots might change):


\setupbodyfont[pagella]

\starttext

\setupmathdelimited
  [topoffset=.2\exheight]

\definemathdelimited
  [fourier]
  [rule=no,
   left=\zerocount,
   right="FE944]

\definemathdelimited
  [courier]
  [rule=no,
   left=\zerocount,
   right="FE946]

\definemathdelimited
  [xourier]
  [rule=no,
   left=\zerocount,
   right="FE948]

$ \fourier{(z+1)} $

$ \fourier{(z+1)} + \sqrt[2]{1}$

$ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $

$ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + 
\xourier{\left(z+\frac12\right)} $


$ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + 
\xourier{(z+\frac12)} $


$ \widehat{x^2 + 2x + 2} $

\stoptext

This example also shows a new \autofences feature and widehats 
(widetilde and widecheck also work that way) that overcome limitations 
in fonts, so


\def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + 
#1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par}

\CrappyHack\widehat
\CrappyHack\widetilde
\CrappyHack\wideacute
\CrappyHack\widecheck

will work. For thise in finance we now have

$ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 
1} $


these are basically radicals (like sqrt) with two sided symbols.

Hans

[NTG-context] Question to footnote settings

[Tomáš Hála via ntg-context]

Hi all,
I am struggling with the width of a footnote number area. I would like to ask 
how can I set it dynamically based on the width of the largest number on a 
given page.

Without width I get two different footnote texts widths (compare #9+10).
With width there is a redundant space on the left (see p. 1).
(Number alignment to the right is required.)

Thanks in advance for some hints.

Tomáš

MWE:
\setupnotation[footnote][

Dear all,

I fear I hit a bug or missed a change.

\starttext
\underbar{First line}\\
Second line.
\stoptext

With lmtx from 2022.07.24 the lines align fine.

With current lmtx the first line has a small indent.


Ciao!

Re: [NTG-context] No error when loading a non-existent module

[Hans Hagen via ntg-context]

On 8/25/2022 2:19 AM, Max Chernoff via ntg-context wrote:

Hi all,

If you load a non-existent module, ConTeXt issues a minor warning, but
otherwise proceeds as normal:

MWE:

\usemodule[doesnt-exist]

\starttext

Hello world!
\stoptext

I think that this behaviour should be changed so that a fatal error is

issued when a loaded module cannot be found. Plain TeX, LaTeX, and OpTeX
all throw an error whenever their versions of modules cannot be found, so
ConTeXt is the odd one out here.

There are 3 scenarios that I can think of for when you attempt to load a
module, but it cannot be found:

1. A module provides some new command "\somecommand"

In this case, loading the module will quietly fail, but an undefined
control sequence error will be issued whenever you use
"\somecommand". This disguises the root problem, which is that the
module was never loaded, potentially confusing users.


It doesn't tell you where to look unless we parse all files.


2. A module changes the layout of a document

In this case, the layout of the document would be unchanged by the
module. If you're looking at every document, then this would be
obvious; however, if you're using some batch processing system, you
could unknowingly send out incorrectly-styled documents quite easily.


Ah ... but texies claim to see the difference so it's an exercise!


3. You load a module that provides some command, then never use it

This is the only case where the new error would break any documents.
However, this case should hopefully be pretty rare since it's
pointless to load a module then never use any of its features.


Indeed harmless.


Making this change could potentially break some documents that currently
work, but I think that this change is worth it, since I'd rather have
something break loudly (throwing an error) rather than silently (producing
a semi-corrupt document).

But ... you can already do

\enabledirectives[logs.errors=*]

or

\enabledirectives[logs.errors=missing modules]

and if needed can add that line to a local cont-loc.mkxl file so that it 
always kicks in.


However, more dangerous is when a user overloads a system macro so if 
you realy want to play safe:


\enabledirectives[overloadmode=error] % or warning

is yuour friend.
