General question: How do understand latex warnings and errors? Is there any documentation on it?

Lots of times I get warnings or errors, but I can never figure out how to decipher them and I can't find any good documentation or guide going through how to understand these errors. For example: enter image description here



I am using latexmk -pdf -pvc. For this, where does the section talking about the errors in Chapter 2. begin? Is it exactly where it says Chapter 2.? Also What is all the other stuff before that talking about? Like the usr/local/texlive/2018... What does it mean T1/cmr/m/n/12 (+20) in the error for Overfull hbox? In general how do I go about reading these?



Also, just as a side question, I can't figure out how to fix those hbox errors. I used to use sloppywhich fixed some errors but those errors aren't being solved using that. I have also tried using usepackagemicrotype which did not fix the problem either.

    Welcome to TeX.SE! I can only see warnings, no errors. (Generally you should not use screen shots for code or text output.) These things happen if LaTeX "thinks" that the line breaks have room for improvements. Depending on what you are doing (you do not provide the source code) providing the hyphenation of certain word in that line may already make this warning disappear. If you want more information, please provide a minimal working example that produces these warnings.

    Yes, we can google code that we can copy more quickly than code that we have to punch in. ;-) More seriously, you see that there are links on the right-hand side. They are generated based on the contents. If your contents contained "overfull", you would see more helpful links even when typing your question.

    Some people are not fortunate enough to be able to read the text in the picture, but they may well have software that can read text to them. It is also more convenient for people who can see the text in the picture when they can copy and paste parts of your error messages to explain them to you. Finally, web searches can pick up text, but are not (yet) great at picking up text from pictures.

    The LaTeX Companion has at the end a good overview over many error messages.

    When I did a quick google search with site:tex.stackexchange.com overfull, I got dragged here, which IMHO provides some good information on parts of your question. In my experience, google searches with site:tex.stackexchange.com in tend to be more efficient than searches with the tool provided by this site (unfortunately).

The comments have pointed you at existing answers describing the general issue but I'll try to describe the log output you show (it would have been a lot easier if you had posted that as text not an image) but I OCR'd the image here:



(/usr/local/texlive/2018/texmf-dist/tex/context/base/mkii/supp-pdf.mkii
[Loading MPS to PDF converter (version 2006.09.02).]
) (/usr/local/texlive/2018/texmf-dist/tex/latex/oberdiek/epstopdf-base.sty
(/usr/local/texlive/2018/texmf-dist/tex/latex/oberdiek/grfext.sty)
(/usr/local/texlive/2018/texmf-dist/tex/latex/latexconfig/epstopdf-sys.cfg))
ABD: EverySelectfont initializing macros ABD: EveryShipout initializing macros
(/usr/local/texlive/2018/texmf-dist/tex/latex/microtype/mt-cmr.cfg) [1/usr/loc
al/texlive/2018/texmf-var/fonts/map/pdftex/updmap/pdftex.map]
(~/CS188Notes.tex
Chapter 2.
Overfull hbox (0.12741pt too wide) in paragraph at lines 27--29
T1/cmr/m/n/12 (+20) brains are good at making rational. But the main problem i
s that brains are not modular
[7] [8] Chapter 3.


The first thing to note is that TeX wraps the messages at a (user settable) width



and then whenever it input a file it logs ( followed by the file path, and when it finishes with that file and processing returns to the file that processed the input Tex logs ).



The graphics package internally does inputsupp-pdf.mkii which on your system gets logged as



(/usr/local/texlive/2018/texmf-dist/tex/context/base/mkii/supp-pdf.mkii


as that is the directory where the file was located. that file identifies itself with a message so then you see



[Loading MPS to PDF converter (version 2006.09.02).]


and a newline then that file is finished so you see ) At this point graphics inputs epstopdf-base.sty which in turn inputs grfext.sty and epstopdf-sys.cfg then you see )) as both levels of input have finished. Then some package outputs two identifying messages prefixed with ABD: then a microtype cfg file is input



(/usr/local/texlive/2018/texmf-dist/tex/latex/microtype/mt-cmr.cfg)


at this point TeX has finished typesetting page 1 and starts to output that page so you see [1 in the log, while generating the PDF for that page it needs to access some font data so you see (wrapped)



/usr/local/texlive/2018/texmf-var/fonts/map/pdftex/updmap/pdftex.map


where ... is a pdftex logging of an internal input as oppsed to the classic (...0 logging of an explicit input.



then you see ] denoting page 1 being finally shipped out.



TeX now presumably sees an input of your CS188Notes file and logs



(~/CS188Notes.tex


The chapter` command in there logs:



Chapter 2.


so up to this point everything is good, the messages are just informational.



Now we see



Overfull hbox (0.12741pt too wide) in paragraph at lines 27--29


So something is .1pt (not very much:-) too wide on the page after page 1 and on line 27 of the source file ~/CS188Notes.tex Te actual text is logged as



T1/cmr/m/n/12 (+20) brains are good at making rational. But the main problem i
s that brains are not modular


so it is that sentence, set in T1 (Latin) encoded computer modern medium weight, normal shape 12pt font, adjusted (+20) by microtype.



then somewhat strangely TeX logs



 [7][8]


which means pages 7 and 8 got output (did you increment the page counter, what happened to pages 2 to 6 ?



Then another chapter command logs



chapter 3


So the only thing wrong is the text about brains where tex couldn't find an ideal line break, it's only .1pt so you could ignore it (if you set hfuzz to .2pt then TeX would not warn about this at all or you may want to adjust the typesetting (or wording) of that paragraph to help with line breaking.
