 ====== SISSA Computing FAQ: about LATEX ======
-To be able to use your class files (with extension .cls) or
-style files (with extension .sty) using LaTeX:
-  * **1)** create in your main directory a subdirectory named texmf, using the following command: **mkdir ~/texmf**\\
+It sometimes happens that you need a new version of some macro package or font; the correct approach is to create a private installation of (La)TeX which includes the new stuff you need.
-  * **2)** copy to this subdirectory the files *.cls or/and *.sty\\
-  * **3)** check which is your default shell using one of the following commands on a linux pc or on ssh.sissa.it: **echo $SHELL**
-  * or if you do not obtain the information, please use: **getent passwd //yourusername// | cut -d: -f7** (for example: //getent passwd falco | cut -d: -f7// )
-=== if the result is: /bin/bash ===
+There are two options: the [[on-line_resources:faq:latex#tex_live_package_manager_tlmgr|TeX Live package manager]] or the [[on-line_resources:faq:latex#manual_mode|manual mode]]
-falco's shell is bash...\\
-If you are using// bash shell//, add into the file **.bashrc** of your main directory the following line:
-  export TEXINPUTS="$HOME/texmf//:$TEXINPUTS"
+===== TeX Live package manager (tlmgr) =====
+<note important>To use the TeX Live package manager, you have to load the ''texlive'' module first </note>
-=== if the result is: /bin/tcsh ===
+Before using ''tlmgr'' in user mode for the first time, you have to set up the user tree with the //init-usertree// action:
-falco's shell is tcsh... \\
-If you are using //tsch shell//, add into the files **.cshrc** of your main directory the following line:\\
-   setenv TEXINPUTS $HOME/texmf//:$TEXINPUTS
+  tlmgr init-usertree
+This command creates a directory named ''texmf'' in your home directory.
-The double slash, after //$HOME/texmf//, is not an error.
+Then, you have to use the //install// action: it checks if the package and all dependencies are already installed in the system installation.  If this is not the case, it installs the package and all dependencies into the user tree (~/texmf).
+  tlmgr --user-mode install pkg
-After you change the appropriate startup files, log out and log back in.
+==== Example ====
+Load ''texlive'' module:
+  $ module load texlive
+Compile a tex file:
+<code>
+$ latex example.tex
+...
+! LaTeX Error: File `memorygraphs.sty' not found.
+Type X to quit or <RETURN> to proceed
+</code>
+Search which package contains //memorygraphs.sty// file:
+<code>
+$ tlmgr search --global --all memorygraphs.sty
+...
+memorygraphs:
+	texmf-dist/tex/latex/memorygraphs/memorygraphs.sty
+</code>
+If it is the first time you use ''tlmgr'', set up the user tree with the command ''tlmgr init-usertree''
+  $ tlmgr init-usertree
+You need to install the package ''memorygraphs'', using the command ''tlmgr --user-mode install memorygraphs''
+<code>
+$ tlmgr --user-mode install memorygraphs
+...
+tlmgr: package repository http://ctan.mirror.garr.it/mirrors/CTAN/systems/texlive/tlnet (verified)
+[1/1, ??:??/??:??] install: memorygraphs [189k]
+running mktexlsr ...
+done running mktexlsr.
+tlmgr: package log updated: /u/j/janedoe/texmf/web2c/tlmgr.log
+</code>
+===== Manual mode =====
+Create in your home directory a subdirectory named ''texmf'', using the following command:
+  mkdir ~/texmf
+Install your new package (or whatever) in a directory structure like this:
+^File extension^Directory^Description^
+|.sty, .cls or .fd|~/texmf/tex/latex/<package_name>/|Style file, Document class file or Font Definition files|
+|.mf|~/texmf/fonts/source/public/<font_name>/|METAFONT outline|
+|.tfm|~/texmf/fonts/tfm/public/<font_name>/|TeX Font Metrics for METAFONT and Type 1 fonts|
+|.vf|~/texmf/fonts/vf/public/<font_name>/|TeX virtual fonts|
+|.afm|~/texmf/fonts/afm/public/<font_name>/|Adobe Font Metrics for Type 1 fonts|
+|.pfb|~/texmf/fonts/type1/public/<font_name>/|PostScript Type 1 outline|
+|.ttf|~/texmf/fonts/truetype/public/<font_name>/|TrueType font|
+|.otf|~/texmf/fonts/opentype/public/<font_name>/|OpenType font|
+|.bst|~/texmf/bibtex/bst/<package_name>/|BibTeX style|
+where:
+  * **//<package_name>//** refers to the name of macro package you are installing. (p.e. //beamer//)
+  * **//<font_name>//** refers to the name of font you are installing (p.e //gothic//)
+and generate an index of that tree
+  mktexlsr ~/texmf
+You can use this approach for updates to packages installed in the SISSA workstations, as well as for installing new versions of things.
