Hello, I created a testing file which tests existence and type of (tex|context|document).(modes|arguments|variables) by Lua - see the attachments.
It seems that:
- Modes are accessible by tex.modes[<a-mode>].
- - tex.modes are 'false' by default. I.e. they are not 'nil' but 'false', even
if not specified on the command line. (tex.mode.__newindex predefined to this
purpose?)
- There is no table of arguments or variables being passed by --arguments="ARG=arg" or by
--variable="VAR=var" from the command line.
- All arguments passed to the command line are accessible by
document.arguments. Unfortunately, when repeating an arg, only the last is
accessible, e.g.
context.exe t.mkiv --arguments="ARG1=arg1" --arguments="ARG2=arg2"
will cause that only (string) "ARG2=arg2" will be in
document.arguments.arguments.
- - That means also that not splitting to key-value pair is not performed by default
(document.arguments.arguments is still "ARG2=arg2", no splitting to
document.arguments.arguments.ARG2 to be "arg2" is not done).
- Not only predefined options/switches, but all args passed by command line are
accessible by document.arguments. I.e. it's possible to call
context.exe t.mkiv --myvar=MYVAR
and later it's possible to get "MYVAR" from document.arguments.myvar.
Let's check the call:
context.exe t.mkiv --arguments=AAA=aaa --mode=MMM --arguments=BBB=bbb
--myvar=MYVAR
Best regards,
Lukas
