Re: [NTG-context] Passing and retrieveing a variable
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

If the passed argument has a NUMBER value, should it be checked against a
number value or a string - so what of the following should be right:
context --arguments=size=1 test.tex
if tex.arguments['size'] == 1 then ...
Or:
if tex.arguments['size'] == 1 then ...
