VISIBLE -- Advice for placing new LaTeX files. Author: Uwe L"uck, http://www.contact-ednotes.sty.de.vu, 2004/10/18; aided by Karl Berry. --derived from a TUGboat (vol. 24) article on Ednotes. * The problem: * E.g., a user downloads a LaTeX file from CTAN. Or: often there is a pair of a .dtx and an .ins file for producing a .sty file. ("Run LaTeX on the .ins file ..." This may be difficult enough, but we assume now that the user manages this.) Typically the user is told to put the (.sty) file to a folder "where LaTeX can find it", or "visible to TeX". Indeed, the user cannot use the file otherwise. However, some users have had no idea how to arrange things so that (La)TeX finds the file. Unfortunately, the procedure for this is somewhat non-trivial indeed. It depends very much on the user's LaTeX installation, so it is difficult to indicate a procedure that helps everyone. * Principles for solutions: * Technically, the searching agent is the TeX program, not LaTeX --we choose our wordings accordingly here. LaTeX is rather a kind of input ("format") to the TeX program. (If this doesn't make sense to you, don't worry about it.) I think of three kinds of approaches: 1. Put the file into the folder where the files you are editing are (call them "job files" here). This is easy; but if the user wants to use the file for another project pursued in a different folder, the approach would require another copy of the file--or a link! Therefore, it has been common to place macro (.sty) or similar files in folders that TeX searches independent of the folder containing the job files. 2. Put the file into a folder that TeX has searched so far. 3. Put the file anywhere (or into an extra folder newly created with care)--and extend the set of folders that TeX searches accordingly. The TeX installation ("shell") usually offers a facility for this--which unfortunately is not always known to the user. * Advice from TeX Users Groups: * I recommend to study the following web pages. The first two of them deal with installation more generally and give some hints that I consider worth to remind of. http://tug.ctan.org/installationadvice http://www.tex.ac.uk/cgi-bin/texfaq2html?label=instpackages These prefer approach 3 of the above, especially the TDS standard of arranging folders, see http://www.tex.ac.uk/cgi-bin/texfaq2html?label=tds The narrower subject matter is concerned at http://{www.tex.ac.uk/cgi-bin/texfaq2html?label=wherefiles * Easy tricks that I prefer: * I must confess that I have never worked with the shells that are chosen as examples on these web pages. Moreover, some Windows users may find the examples little helpful. So my personal hints use approach 2 of the above. o Typically, the file is from CTAN folder /tex-archive/macros/latex/contrib/, and you find a folder .../latex/contrib/ in the installation at your workplace. Then the latter should be a good guess for placing the new file. o You may find a folder .../texinput/ (or TeXinput!?) which should be another good guess. o Search your installation for files with the same file name extension (usually `.sty'), try their folder. (Updates are a special case of the last idea, of course.) Ok, if all this doesn't help, you may ask at comp.text.tex or your local TeX guru. Good luck!
