How to use defines in other files?












0















I can properly use a define



def <command> <parameter-text>{<replacement-text>}


if it is define in the same LaTeX file, which is not the main file, but let's say, it is named 2.intro.tex which is included with input{section/2.intro}.



However, if I put the define in the main.tex of even in another file which in included before 2.intro, it does not work. When compiling, it says
! Undefined control sequence.



Any help on how to solve this problem?





main.tex



documentclass[letterpaper, 10pt]{elsarticle}                                      

usepackage{lipsum}

begin{document}

begin{frontmatter}
defmylabel{[My Label in Main2]}
lipsum[1]
end{frontmatter}
input{intro}

end{document}




intro.tex



lipsum[1]

    input has no effect on the scope of commands, tex works just as if the contents of the file were copied at that place, so if you get undefined commands the error will be elsewhere. post a small example that shows the problem.

  • I guess I the problem is having anything defined between begin and end, I just realized that now.

    Indeed begin{foo}...end{foo} generally comes with an implicit group so that definitions inside the environment stay local to that environment unless they are explicitly made global.

This is unrelated to input you would see the same from



documentclass[letterpaper, 10pt]{elsarticle}                                      

usepackage{lipsum}

begin{document}

begin{frontmatter}
defmylabel{[My Label in Main2]}
lipsum[1]
end{frontmatter}
mylabel

end{document}


You want the definition outside the group so



documentclass[letterpaper, 10pt]{elsarticle}                                      

usepackage{lipsum}

begin{document}
