Title formatting the section makes the bibliography header disappear












0















I used a section style that I found here.
The problem is that the header of the bibliography becomes a box even though I've tried to make a separate style for unnumbered sections.

Edit: This is the error message that shows up:

can't handle. Either drop the braces or make the material unbreakable
using an mbox (hbox). Note that a space also counts as possible
hyphenation point. See page 4 of the manual. I'm leaving a black
square so that you can see where I am right now.

The problem seems the unexpanded name of the section (if I'm not mistaken). The following completely expands the given name with an edef expansion (this might produce new issues, I'm not sure). It however works for your MWE:

Alternative



The following defines an alternative style, that formats unnumbered sections similar to the numbered ones (it uses report and also defines chapter to be matching, just remove that and you're good to go with article). It also removes the unnecessary repetition of calling titleformat for each sectioning level by defining a shorthand macro.

Alternative 2



This version should look identical in print, but the display of the PDF depends on the viewer (xpdf can be trusted, though; this is because using ulem the lines are built using small segments which might lead to aliasing issues on screens). It breaks automatic hyphenation, but remains line breakable. It uses the ulem package instead of the soul package. ulem should be robuster, and therefore the edef expansion is not needed with it.

The lines do align vertically with the box of the section numbers (checked with xpdf at 2000% magnification), the mismatch is due to Gimp's rasterization.

    This version should look identical in print, but the display of the PDF depends on the viewer (xpdf can be trusted, though; this is because using ulem the lines are built using small segments which might lead to aliasing issues on screens). It breaks automatic hyphenation, but remains line breakable. It uses the ulem package instead of the soul package. ulem should be robuster, and therefore the edef expansion is not needed with it.

        Alternative 2



        This version should look identical in print, but the display of the PDF depends on the viewer (xpdf can be trusted, though; this is because using ulem the lines are built using small segments which might lead to aliasing issues on screens). It breaks automatic hyphenation, but remains line breakable. It uses the ulem package instead of the soul package. ulem should be robuster, and therefore the edef expansion is not needed with it.

        The lines do align vertically with the box of the section numbers (checked with xpdf at 2000% magnification), the mismatch is due to Gimp's rasterization.

        The problem seems the unexpanded name of the section (if I'm not mistaken). The following completely expands the given name with an edef expansion (this might produce new issues, I'm not sure). It however works for your MWE:

        Alternative



        The following defines an alternative style, that formats unnumbered sections similar to the numbered ones (it uses report and also defines chapter to be matching, just remove that and you're good to go with article). It also removes the unnecessary repetition of calling titleformat for each sectioning level by defining a shorthand macro.

            Image
            2 2 I have a Zotero bibliography in Overleaf. I use biblatex . usepackage[backend=biber,citestyle=authoryear]{biblatex} addbibresource{zoteroALH.bib} Bibliography entries look like: @book{de_saint-gervais_uniformization_2016, title = {Uniformization of {Riemann} {Surfaces}}, isbn = {978-3-03719-145-3}, url = {https://www.ems-ph.org/books/book.php?proj_nr=198&srch=series%7Chem}, urldate = {2019-02-03}, author = {de Saint-Gervais, Paul Henri}, year = {2016}, doi = {10.4171/145} } In the bibliography down the paper the reference shows like this: There is the DOI, great, but also the URL which is unnecessary when the DOI is there.

            ComboBox Display Member on multiple fields

            Image
            2 I'm trying to set the .DisplayMember property of a ComboBox in C#, but I want to bind it to multiple columns in the .DataSouce .

            Is it possible to collect Nectar points via Trainline?

            Image
            2 Since I am not eligible for any Railcard, the only available discount/bonus scheme is Nectar Card for me. GWR, SWR, LNER and Virgin Trains allow to collect Nectar points and I have already linked a card to my GWR account. A friend suggested me to use Trainline App, because it can search for bus tickets either. I had a look at the application, but could not see any option for Nectar.
