Would it make more sense, or would it be “cleaner” to use a variable?
You can get rid of the temp variable before the command definition but
now you have to access it with a different method in \mymacro, below is
one way (LMTX only) but \setvariable and \getvariable work as well.
\define[1]\mymacro
{\iftok{#1}{\getvalue{previousmymacro}}%
same as last time
\else
it is different from last time
\fi
\setvalue{previousmymacro}{#1}}
That was the approach that I meant. Thank you.
But would you consider one way to be better?
Just for fun: lua code
\startluacode
local previous = nil
interfaces.implement {
name = "mymacro",
public = true,
arguments = "string",
actions = function (current)
if current == previous then
context("same as last time")
else
context("Different!")
end
previous = current
end,
}
\stopluacode
\starttext
\startlines
cat: \mymacro{cat}
cat: \mymacro{cat}
mouse: \mymacro{mouse}
mouse: \mymacro{mouse}
cat: \mymacro{cat}
\stoplines
\stoptext
keep in mind that what you do is global (probably what one wants here):
\startlines
cat: \mymacro{cat}
cat: \mymacro{cat}
{mouse: \mymacro{mouse}}
{mouse: \mymacro{mouse}}
cat: \mymacro{cat}
\stoplines
