output was without newlines in between<br>
the macro parameters:<br>
\foo #1#2-><br>
#1<-a<br>
#2<-b<br>
<br>
Now luatex (TL2023 Version 1.17.0) outputs extra newlines:<br>
\foo #1#2-><br>
<br>
#1<-a<br>
<br>
#2<-b<br>
<br>
TL2023 pdftex outputs standard (old) format without extra newlines.<br>
With these extra spaces seems harder to follow up the code output.<br>
<br>
Real output example (enabled \tracingmacros and \tracingcommands):<br>
<br>
\strip@pt ->\expandafter \rem@pt \the |<br>
{\expandafter} | these lines looks like one block and its easy to <br>
follow up<br>
{\the} |<br>
<br>
\rem@pt #1.#2pt->#1\ifnum #2>\z@ .#2\fi <br>
|<br>
|<br>
#1<-10 |<br>
| this block is harder to follow up<br>
#2<-0 |<br>
{\ifnum} |<br>
{false} |<br>
<br>
<br>
Is this done on purpose? Could it be available original style (like <br>
pdftex does) with some \tracingmacros value (like \tracingmacros=3)<br><br></blockquote><div><br></div><div>iirc it's configurable by mean of the input_level_string callback, e.g. see what happens in lualatex</div><div><br></div><div> \documentclass{article}</div>\def\foo#1#2{#2#1}<br>\begin{document}<br>\tracingmacros1<br>\tracingstacklevels1<br>\foo{h}{e}llo<br>\tracingmacros0<br>\tracingstacklevels0<br>\end{document}<br></div><div class="gmail_quote"><br></div><div class="gmail_quote">--</div><div class="gmail_quote">luigi</div></div>
