How to cross referencing between different files in TeX LaTeX?
To expand on @MadyYuvi’s answer, if you use the subfiles package you can just put your references in as you would in a single document, and they will compile and work just fine. This worked wonders for me. Thanks for contributing an answer to TeX – LaTeX Stack Exchange!
How to import a preamble from a subfile?
The parameter inside brackets tells LaTeX to import the preamble from each subfile (packages are imported only once), if omitted, make sure you have all the necessary commands in the main document preamble for the subfiles to work. One must be careful because of possible incompatibilities in the different preambles.
Do you need to use hyperref to cross reference?
If the references are coming from another Beamer document, there is no need to do anything. If they are coming from a basic LaTeX document you may need to add \sepackage {hyperref} and typeset the source document again. As far as I can tell, there is no downside to always using hyperref.
How to cross referencing between XR and Beamer?
Beamer and xr: If you want to use the xr package to pull external references into a Beamer document, you need to be sure that the source of the references has been typeset using the hyperref package. This is because Beamer uses hyperref by default and the format of the references in the .aux file is different for hyperref.
How to include source code in a LaTeX document?
I’ve written the matlab package for including code in LaTeX documents. The matlab package includes an mtext environment for code blocks, VerbListing , VerbListingBoxed , VerbListingNumber commands for including source code from external files, and the Listing environment to include code in a float environment.
How to use the XR package in latex?
You can use the xr package to reference to other LaTeX document. And then can use ef {a} like normal. You can also add a prefix: then you can reference it as ef {I-a} which is useful if you have identical label names in different chapters. Note that the normal xr doesn’t add hyperlinks. It only adds the label text.
How to cross reference a document in overleaf?
On Overleaf cross references work immediately, but for cross references to work properly in your local LaTeX distribution you must compile your document twice. There’s also a command that can automatically do the job for all the references to work. For instance, if your document is saved as main.tex.
