No trace of LaTeX format version apart date of dump in log

[jfbu]

Brief outline of the bug

When I compile minimal document and check the log I can not tell which version of LaTeX format is in use. I am mentioning this in relation to recent April 2018 release.

This is pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2018) (preloaded format=pdflatex 2018.4.9)  10 APR 2018 15:54

I get information about packages such as latexbug which I added as per instructions, and article class. The preloaded format=pdflatex 2018.4.9 only tells me the format was built yesterday.

I (=lambda user of LaTeX posting a question on tex.sx and asked to provided the log) have no way of knowing that I am using the April 2018 version of LaTeX, in particular regarding its incorporation of UTF8 as default.

Minimal example showing the bug

\RequirePackage{latexbug} 
\documentclass{article}

% nothing here

\begin{document}

  % nothing here either here
  
\end{document}

Log file (required) and possibly PDF file

temp.log

We've changed nothing here in that regard, and for me the usual line gets printed

Which OS are you using?

[jfbu]

I am on MacOS 10.9.5. The binaries are built on my locale using an rsync'ed TeXLive source. I will check with binaries from darwin-legacy.

If you use pdflatex test then it is logged but if you use pdflatex \input test then the banner comes to the terminal but not the log, I see the same in (for example ) texlive 2016 David

indeed, this is compiled from Emacs/AUCTeX buffer which does \input

[jfbu]

yes, as David says, from command line it is ok

(the above has added ééé in source sorry and inputenc explicit loading for testing)
with darwinlegacy this time binaries and rebuilt formats (not that it should change anything as far as I know)

[davidcarlisle]

I think this is just a feature of tex that if you use commands on the commandline then the `\everyjob` banner is executed before tex has frozen \jobname so the typeout just goes to the terminal as the log is not open.

Sorry for noise, indeed it was already like this in TL2017. When compiling from command line, I got then the

LaTeX2e <2017-04-15>

line both on Terminal and in log

But from Emacs/AUCTeX buffer the LaTeX2e stamp is only in process output, it is not in log file.

Never had noticed that...

[davidcarlisle]

Feature of the tex engine if making messages before \jobname is fixed, This has always been this way.
