I have a problem with capturing returned value of my command.
Here is my preamble with command definition:
documentclass[convert=density=300,size=800x600,outext=.png]standalone
usepackage[utf8]inputenc
usepackagetikz
% Font used for writing commands.
defcmdFontfontsize1012selectfont
% Commands.
defcmdOne cmdFont aaa
defcmdTwo cmdFont bbbbb
defcmdThreecmdFont cccc
% Function which returns maximum width needed to write any of provided arguments.
makeatletter
newlengthtextLength@getMaximumWidthHelper
newlengthtextLength@getMaximumWidth
newcommandgetMaximumWidthHelper[2]
%
settowidthtextLength@getMaximumWidthHelperpgfinterruptpicture #2endpgfinterruptpicture%
pgfmathparsemax(#1,textLength@getMaximumWidthHelper)%
@ifnextcharbgroupgetMaximumWidthHelperpgfmathresult ptpgfmathresult pt%

%
settowidthtextLength@getMaximumWidthpgfinterruptpicture #1endpgfinterruptpicture%
@ifnextcharbgroupgetMaximumWidthHelperthetextLength@getMaximumWidththetextLength@getMaximumWidth%
%
makeatother
Working example used to test the above command:
begindocument
getMaximumWidthcmdOne
getMaximumWidthcmdOnecmdTwo
getMaximumWidthcmdOnecmdTwocmdThree
enddocument
However, when I try to capture the output of getMaximumWidth, it doesn't work as expected.
begindocument
newlengthmaximumWidth
setlengthmaximumWidthgetMaximumWidthcmdOnecmdTwocmdThree
themaximumWidth
enddocument
On the second line, the return value of getMaximumWidth is not captured but instantly printed.
Afterwards I get an error:
! Missing number, treated as
zero.
After that, the third line just prints default value 0.0pt.
What is the proper way to capture the output of getMaximumWidth?
P.S. This is my first time writing Latex document, feel free to point out anything i could've done better.

while@ifnextcharbgroupworks you should almost never do it as it results in commands that fail to obey latex syntax conventions. All latex commands have a fixed number of arguments usingdelimiters and a variable number of optional arguments which use[]delimiters. You have defined a command with optionalarguments which is wrong.

I'd generalize settowidth and, by the way, get also height and depth for free.

Thank you! I won't lie, I have absolutely no idea what you did, but the usage at the end is pretty neat.

I've read a bit and now that I understand what you did with this Elvish syntax, it's even more impressive! Luckily I think I'll just need the width, so I'll dumb it down a little.

while
@ifnextcharbgroupworks you should almost never do it as it results in commands that fail to obey latex syntax conventions. All latex commands have a fixed number of arguments usingdelimiters and a variable number of optional arguments which use[]delimiters. You have defined a command with optionalarguments which is wrong.– David Carlisle

macros do not have return values, your
getMaximumWidthexpands to a series of assignments so is not a length that can be used insetlength, you need to define it to leave a length in some command, saytempresultthen usegetMaximumWidthcmdOnecmdTwocmdThreesetlengthmaximumWidthtempresultor using a latex-conforming syntax,getMaximumWidthcmdOne,cmdTwo,cmdThreesetlengthmaximumWidthtempresult– David Carlisle

Thanks a lot! I am not able to test everything at the moment, but your solution seems a lot easier and can be used as I intended.
