"error not related to input file"

"error not related to input file"

[Rudolf Bahr]

Hello All,

In:
LuaMetaTeX, Version 2.03.3
ConTeXt  ver: 2019.12.12 19:35 MKIV beta  fmt: 2019.12.12  int: english/english
I get the following error message:

tex error       > error not related to input file:
tex error       >   tex: ! Emergency stop
tex error       >   lua: ?
tex error       >   mps: -

Sorry, no MWE available.
What does this message mean? [1] shows only an empty page.
To this point my programm does all what it should with the exception of creating
a grey pdf-file-page. My pdf-programs are okular and xpdf.

In:
LuaTeX, Version 1.11.2 (TeX Live 2020/dev)
ConTeXt  ver: 2019.12.12 19:23 MKIV beta  fmt: 2019.12.13  int: english/english
I get a "*" instead of the error message above. And again my program does all what
it should, but a grey pdf-page too.

Shure, there must be an error in my program. But where should I look for it?
I tried several MWEs, but they all worked at their best.

Please, any ideas?

Best wishes,
Rudolf

Sorry, I forgot:
My program uses up to now mainly \startluacode ... \stopluacode.

Hi,

Since I have also suffered somewhat from the cryptic (and often useless…) error messages, I understand your frustration :-)
Now, maybe if you do 
	context --directives="system.showerror" myfile.tex
then you get a file named « myfile-status.html » which is more helpful.

Best regards: OK

normally an * means: waiting for input .... and no message is then 
involved as in principle there is no real error, apart from waiting for 
input

Otared and Hans, thank you for your answers and Otared especially for your
sympathy! :-)

In the meantime I could get rid of "! Emergency stop" and "*" by changing
a \def-command which calls a luacode subprogram; see further down in my MWE.

My program run now looks essentially better, but "--directives="system.showerror" 
and "<my program>-status.html" still report an error: "! Undefined control sequence"
without telling which control sequence is undefined. How reliable is this error
message? I don't know of control sequences in luacode or what does this error message
mean?

Here is a MWE which shows my program structure. Sorry, this MWE works really :-)
During my attempts to find the error I got for a short time the message: "Invalid
\starttext ... \stoptext structure" which I don't understand.

--------------------------------------------------- MWE -------------------------------
\def\projectpath{/home/sam/trip-2019/}

\startluacode
   userdata = userdata or {}
   u = userdata

   function u.table_save ( tab, file )
      local tab   = tab
      local file  = file

      dofile ("table_save_u_table_load.lua")
      table.save(tab, file)
   end


   function u.Init ( col )

      local col  = col 
      local ppth = tokens.getters.macro("projectpath")
      local xO   = tokens.getters.macro("xO")
      local yO   = tokens.getters.macro("yO")

      local I = {}	-- Table of initial values
      I ["projectpath"] = ppth
      I ["column"]      = {}
      I ["column"][col] = {}
      I ["column"][col]["layerpos"] = {}
      I ["column"][col]["layerpos"] ["xO"] = xO
      I ["column"][col]["layerpos"] ["yO"] = yO

      u.table_save(I,"I-Table.lua") 
   end
   
\stopluacode

%\def\Init #1 {\ctxlua {u.Init ([==[#1]==]) }}% --the blanks produced my "! Emergency stop"
\def\Init#1{\ctxlua{u.Init([==[#1]==])}}%       --in this form the command works 

\starttext
   \def\Column{A}%
   \def\xO{0}%  in pt
   \def\yO{20}% in pt

   \Init{\Column}%%
\stoptext
---------------------------------------------------------------------------------------
For those possibly interested in running this MWE I append "table_save_u_table_load.lua",
a lua program to save and reload lua tables, found in the lua homepage. Anyway, the
resulting flattened table "I" is here:

return {
-- Table: {1}
{
   ["column"]={2},
   ["projectpath"]="/home/sam/trip-2019/",
},
-- Table: {2}
{
   ["A"]={3},
},
-- Table: {3}
{
   ["layerpos"]={4},
},
-- Table: {4}
{
   ["yO"]="20",
   ["xO"]="0",
},
}



I think nobody will be able to help me in this case, I myself have to try again and 
again to finally find the error. If so, this would be the nicest christmas gift to me :-)

Best regards,

Rudolf
