TeX - LaTeX Asked on October 4, 2021
I’d like to iterate over a list of values, which is stored inside a variable.
The problem is that the list of items (myList
in the MWE) to iterate over is the value of a previously-declared variable (mydata
).
This nested declaration breaks the iteration, as shown in the MWE. Indeed, iterating over myData
does not give any problems while iterating over myList
does.
documentclass{article}
usepackage{pgffor}
setlengthparindent{0pt}
defmyData{1,2}
defmyList{myData}
begin{document}
section*{Variables}
Mydata : myData
Mylist : myList
section*{Iteration over myList}
Somewhere this is broken due to the variable declaration...
foreach x in myList
{
Item x
}
section*{Iteration over myData}
foreach x in myData
{
Item x
}
end{document}
How can I make the variable re-definition not break the iteration ?
I cannot do otherwise since this MWE is a excerpt of a much broader project.
It is an expansion issue. If you use edefmyList{myData}
or edefmyList{myData}
then your code will work:
documentclass{article}
usepackage{pgffor}
setlengthparindent{0pt}
defmyData{1,2}
edefmyList{myData}
begin{document}
section*{Variables}
Mydata : myData
Mylist : myList
section*{Iteration over myList}
Somewhere this is broken due to the variable declaration...
foreach x in myList
{
Item x
}
section*{Iteration over myData}
foreach x in myData
{
Item x
}
end{document}
