Error with ling-macro and expex package

add tag

निरंजन

Have a look at [this](https://tex.stackexchange.com/a/230012/174620) answer. I tried using this with package `ling-macros` and it results in some errors. The macro names `\lb` and `\rb` were already used in package `ling-macros`, hence I used `\lbz` & `\rbz`. Can someone help debugging this?

```
\documentclass[12pt]{article}
\usepackage{expex}
\usepackage{ling-macros}
\newcommand{\lbz}{\upshape[}
\newcommand{\rbz}[1]{\upshape]\textsubscript{#1}}

\begin{document}
\ex
\begingl
  \gla \nogloss{\lbz\lbz}  Mon ami \nogloss{\rbz{NP}}     est  \nogloss{\lbz} grand \nogloss{\rbz{AP}}//
  \glb my friend is tall//
  \glft `My friend is tall'//
\endgl
\xe
\end{document}
```

I'd prefer not to since I am not at all familiar with these packages. The above suggestions could be bad practice. Usually one should avoid loading packages that have public macros of the same name but different definitions. Maybe an expert shows up and can make a more sustainable suggestion. The debugging stuff is another question IMHO. Maybe one day some question on this shows up, and different users can detail their strategies. Or a community Wiki to have a single structured document that others can use.

I wouldn't call myself an expert. But yes, there is a number of debugging tools available. There are extended tracing tools available. They are surveyed in chapter 34 of TeX by Topic, which you should get by invoking `texdoc texpytopic` on your console.

Yes, I think this was the reason for the error message. You can use the `\show` command to figure such things out. The error message that the command before `\begingl` was to blame, which is `\ex`. So I did ``` \documentclass[12pt]{article} \usepackage{expex} \show\ex \usepackage{ling-macros} \show\ex ... ``` to get ``` > \ex=macro: ->\bgroup \@tildecheck \ex@a . l.3 \show\ex ``` and ``` > \ex=macro: ->\@ifnextchar [{\@ex }{\item }. l.5 \show\ex ``` These two definitions differ, so voila. However, I made no attempt to identify further macro duplicates. Since the packages seem to serve related purposes, chances are that there are further pitfalls. Yet maybe `\show` will show a way to deal with those if they exist.

Oh!!! That was the culprit. It has a simpler solution then. `expex` has `\pex` which can be used for this purpose :) ``` \documentclass[12pt]{article} \usepackage{expex} \usepackage{ling-macros} \begin{document} \pex \begingl \gla Mon ami est grand// \glb my friend is tall// \glft `My friend is tall'// \endgl \xe \end{document} ```

@निरंजन, re: [your question](#question), Not sure if this is a reasonable suggestion. `ling-macros` also redefines `\ex` and `\xe`. If you remember the original definitions, the errors will disappear. ``` \documentclass[12pt]{article} \usepackage{expex} \let\oldex\ex \let\oldxe\xe \usepackage{ling-macros} \newcommand{\lbz}{\upshape[} \newcommand{\rbz}[1]{\upshape]\textsubscript{#1}} \begin{document} \oldex \begingl \gla \nogloss{\lbz\lbz} Mon ami \nogloss{\rbz{NP}} est \nogloss{\lbz} grand \nogloss{\rbz{AP}}// \glb my friend is tall// \glft `My friend is tall'// \endgl \oldxe \end{document} ```` ![Screen Shot 2020-10-16 at 11.45.07 PM.png](/image?hash=0a3b64c0993506effc07ee3207371c2f5feed82d15b3f98d95c941fad938a645) However, there is no warrantee that there no further clashes. (You might also try to set `\ex` to the remembered command, but I am not sure if this makes sense either.)
