Why \doifelse and \ifx are evaluated as false
Hello,
I'm trying to test whether value of \jobname is "Test"; I suppose it should be as the
file name is "Test.mkiv".
But the code:

I can confirm the problem. I
in a tex.write which is wrong
so we need to revert to this:
\def\syst_write_execute#1%

\unexpanded\def\write#1#%
{\ifnum#1=18
\expandafter\syst_write_execute

(context itself doesn't suffer from this as it does things
values but at least they return something) but
something like this works:
\def\syst_write#1#2%
{\ctxcommand{write(\number#1,\!!bs\normalunexpanded{#2}\!!es)}}
\unexpanded\def\writeviatex#1#2%

I strongly ask that ConTeXt abstains from changing the definition of \month and

In core-con.mkiv, the `month` conversion calls `\monthlong`, which
calls the Lua command.month. But that prints the number of the current

Hello,
sometimes in this mail discussion I'm encountering a Ctx/Lua command which has
been unknown for me or I would use other (known) commands to do the job.
So - would it be possible to explain
- what's the difference/advantage btw \directlua and \ctxlua
- what \ctxcommand{} does
- what
/advantage btw \directlua and \ctxlua
No difference, just another name, there are even more synonyms.
- what \ctxcommand{} does
\ctxcommand{...} == \ctxlua{commands}
- what \cldcontext{} does?
\cldcontext{...} == \ctxlua{context(...)}
There is also \cldcommand{...} which is a short form
sorts of things that are tricky in TeX:
\ctxlua{ commands.doifelse( string.len( -45 ) 5 ) }{long}{short}
Cheers,
Sietse
... Has been wikified -

For functions in the commands namespace you can write e.g.
\ctxcommand{doifelse(…)}{…}{…} instead
) }{long}{short}

... I also found another solution reposter before:
\ctxlua{commands.testcase(condition)}
{ If true...}
{If false}
Note that both blocks (if-true and if-false) are mandatory.
Considering Wolfgang's last answer, it would be better to write:
\ctxcommand{testcase(condition
{scrn_attachment_method_\v!hidden}%
{\ctxcommand{insertattachment{
tag= \currentattachment,
registered = \currentattachmentregistered,
method = \v!hidden
}}}
While such anonymizing mode may be required for some security-obsessed
people, who do not want filenames leak into shipped out
need a raw untagged and expandable fetch:
\def\rawstructurelistuservariable#name%
{\ctxcommand{listuserdata(\currentlist,\currentlistindex,#name)}}

% so, after some 5 lines patching we can do:
\starttext
\startplacefigure[reference=fig:mill,title={A Mill}][resource=mill
: in
function 'notedeltapage'
main ctx instance:1: in main chunk.
and finishes with:
\ctxcommand ...\directlua \zerocount {commands.#1}
\strc_notes_set_style_color_special ...tenumber
