Defined command only works in preamble










2















I'm writing a class, and when using it I want to use small caps with a font that doesn't have small caps defined (I know – not as good as the real thing). I found this answer Fake small caps with XeTeX/fontspec? which I tried to include, however I get the errors:



Missing $ inserted.
Missing $ inserted.
You can't use 'spacefactor' in vertical mode.



However, the code works perfectly when it's pasted into the preamble.



Anyone know what's going on?

    Welcome to TeX.SX! Without seeing your code it is impossible to say what the problem is. Can you please add a minimal working example. A MWE should start with a documentclass command, have a minimal preamble and then begindocument...enddocument. The code should compile and be as small as possible to demonstrate your problem. Cutting your code down to a MWE may well reveal what your problem actually is. In any case, it is really difficult to help you without more information.

    please don't just post disconnected code fragments, post a single small example that we can run to get the error that you are asking about, otherwise it's very hard to guess the error and advise how to fix it.

    As David says, please post a full minimal working example: the code should be as small as possible so as to reproduce your error. You should either post a minimal latex document that exhibits the problem or, alternatively, a minimal class file together with a minimal latex document. The key thing is that we should be able to reproduce your error from the code that you post. It is virtually impossible to help you if you don't show us the problem.

    There still is a makeatletter and a makeatother in your .cls file. Remove all makeatletters and makeatothers from the .cls. As I said before if I remove all of them (in the earlier version two pairs, now only one pair), the MWE compiles.

First and foremost: faking small caps for a font that hasn't them is hopeless.




When LaTeX is reading a .cls file, makeatletter is implicitly in force and issuing makeatother will most likely introduce problems.



Indeed it does, because when we arrive at defining maketitlee, @ is an “other character”, so the definition becomes



• •makeatletter•@•t•i•t•l•e•makeatother•


( is used to separate tokens). Note that when maketitlee is called, the replacement text has already been tokenized, so makeatletter will do nothing at all.



Never use makeatletter and makeatother in a .cls file except in the body of a macro definition that has among its actions inputting a file where the special treatment of @ is needed. This is not the case of your maketitlee macro.




After removing makeatletter and makeatother everywhere in the class file, compiling your example .tex file produces no error and the output is



enter image description here



that clearly shows what I mean in the top line of this answer.

    In some situations better than makeatletter..makeatother is: begingroupmakeatletter@firstofoneendgroup <Stuff where @ must be letter> . This way the category code of @ will be reset to whatever it was before issuing the makeatletter-command. makeatother does set the category code of @ to 12 (other) no matter what it was before.

( is used to separate tokens). Note that when maketitlee is called, the replacement text has already been tokenized, so makeatletter will do nothing at all.



Never use makeatletter and makeatother in a .cls file except in the body of a macro definition that has among its actions inputting a file where the special treatment of @ is needed. This is not the case of your maketitlee macro.




After removing makeatletter and makeatother everywhere in the class file, compiling your example .tex file produces no error and the output is

that clearly shows what I mean in the top line of this answer.

  • Something that may throw a spanner in the works, after seeing this comment tex.stackexchange.com/questions/459738/… I realised I needed to modify the MWE given, for me that MWE doesn't successfully compile.

    In some situations better than makeatletter..makeatother is: begingroupmakeatletter@firstofoneendgroup <Stuff where @ must be letter> . This way the category code of @ will be reset to whatever it was before issuing the makeatletter-command. makeatother does set the category code of @ to 12 (other) no matter what it was before.
