you can test for environment.arguments.currentrun being "1"


btw, there's also

   if tex.systemmodes["first"] then


Thank you Hans... but it doesn't fully work. Now I only enter the input
once (that's ok) but on the second run, the variable is not defined
anymore. How can I keep it in the conTeXt memory?

-- Minimum still not working example
local name
if environment.arguments.currentrun == "1" then io.read() end
context.startdocument()
context("Hello " .. name)
context.stopdocument()


jobvariables.save("SomeName",value)

jobvariables.restore("SomeName")

beware, this also creates \SomeName

You can use the LUA interface "job.passes".
In the first pass, you store your value. For example:
local passdata = job.passes.define("mystuff") --I usually define this at 
the top of my script and reuse it.

passdata["somevalue"] = "hello world";

Then in the subsequent runs you can access
local lastpassdata = job.passes.getcollected("mystuff") --Same here...
print(lastpassdata["somevalue"])

Best regards,
Andreas

Thank you Hans... but it doesn't fully work. Now I only enter the input
once (that's ok) but on the second run, the variable is not defined
anymore. How can I keep it in the conTeXt memory?

[NTG-context] Howto use the lua io.read() function only in the first context run?

2016-03-15 Thread Romain Diss
Hi all,

I want to write a cld document with some data read on the standard
input. I'm using the lua io.read() function but it's launched at every
context passes (depending on the case, it is launched 2 to 3 times).

-- Minimum not working example
local name = io.read()
context.startdocument()
context("Hello " .. name)
context.stopdocument()

Thanks in advance.
