# Difference between revisions of "TeX Live"

TeX Live is an "easy way to get up and running with the TeX document production system. It provides a comprehensive TeX system with binaries for most flavors of Unix, including GNU/Linux, and also Windows. It includes all the major TeX-related programs, macro packages, and fonts that are free software, including support for many languages around the world."

TeX Live is one of the most popular distributions for LaTeX, ConTeXt and friends.

## Installation

The TeX Live packages are arranged into two groups in the official repositories:

The essential package texlive-core contains the basic texmf-dist tree, while texlive-bin contains the binaries, libraries, and the texmf tree. texlive-core is based on the “medium” install scheme of the upstream distribution. All other packages are based on the eponymous collections in TeX Live. To determine which CTAN packages are included in each package, lookup the files:

``` /var/lib/texmf/arch/installedpkgs/<package>_<revnr>.pkgs
```
Note: texlive-langextra provides language support for African, Arabic, Armenian, Croatian, Hebrew, Indic, Mongolian, Tibetan and Vietnamese.

### Manual installation

See the LaTeX Wikibook and TeX Live Guide. For programs that require TeX Live to be installed (e.g. kile) you can use the texlive-dummyAUR package.

## Usage

You can test your installation with

```\$ tex '\empty Hello world!\bye'
\$ pdftex '\empty Hello world!\bye'
```

You should get a DVI or a PDF file accordingly.

You will probably want a TeX editor. There are also a few online solutions that let you create TeX-based documents without TeX Live. See the LaTeX wikibook.

## Important information

• The biber utility used to handle biblatex bibliography is provided as a separate package.
• The way to handle font mappings for updmap was improved in September 2009, and installation should now be much more reliable than in the past. In the meantime, if you encounter error messages about unavailable map files, simply remove them by hand from the `updmap.cfg` file (ideally using `updmap-sys --edit`). You can also run `updmap-sys --syncwithtrees` to automatically comment out outdated map lines from the config file.
• The ConTeXt formats (for MKII and MKIV) are not automatically generated upon installation. See the ConTeXT wiki for instructions on how to do this.
• The packages containing the documentation and sources are no longer available in official repositories. You can locally build them with tllocalmgr. You can also consult documentation online at https://tug.org/texlive/Contents/live/doc.html or on CTAN. Another possibility is using the online documentation at `http://texdoc.net/pkg/packagename` which resolves to the relevant pdf for `packagename`, similar to the command line tool `texdoc` (which is useless without locally installed documentation).
• TeX Live (upstream) now provides a tool for incremental updates of CTAN packages. On that basis, we also plan to update our packages on a regular basis (we have written tools that almost automate that task).
• System-wide configuration files are under `/usr/share/texmf-config`. User-specific ones should be put under `~/.texlive/texmf-config`. `\$TEXMFHOME` is `~/texmf` and `\$TEXMFVAR` is `~/.texlive/texmf-var`.
• A skeleton of a local texmf tree is at `/usr/local/share/texmf`: this directory is writable for members of the group tex.

### Paper Size

If you would like to set the default page size to something other than A4 (such as "Letter"), run the following command:

```\$ texconfig
```

This command is also capable of changing other useful settings.

### Error with "formats not generated" upon update

See this bug report. (Note that if you do not use the experimental engine LuaTeX, you can ignore this.) This situation typically occurs when the configuration files `language.def` and/or `language.dat` for hyphenation patterns contain references to files from earlier releases of `texlive-core`, in particular to the latest experimental hyphenation patterns for German, whose file name changes frequently. Currently they should point to `dehyph{n,t}-x-2009-06-19.tex`.

To solve this, you need to either remove these files: `/usr/share/texmf-config/tex/generic/config/language.{def,dat}` or update them using the newest version under: `/usr/share/texmf/tex/generic/config/language.{def,dat}` and then run

```# fmtutil-sys --missing
```

### Fonts

By default, the fonts that come with the various TeX Live packages are not automatically available to Fontconfig. If you want to use them with, say XeTeX or LibreOffice, the easiest approach is to make symlinks as follows:

``` ln -s /usr/share/texmf-dist/fonts/opentype/public/<some_fonts_you_want> ~/.fonts/OTF/ (or TTF or Type1)
```

To make them available to fontconfig, run:

``` fc-cache ~/.fonts
mkfontscale ~/.fonts/OTF (or TTF or Type1)
mkfontdir ~/.fonts/OTF (or TTF or Type1)
```

Alternatively, texlive-core contains the file `/etc/fonts/conf.avail/09-texlive-fonts.conf` that contains a list of the font directories used by TeX Live. You can use this file with:

`# ln -s /etc/fonts/conf.avail/09-texlive-fonts.conf /etc/fonts/conf.d/09-texlive-fonts.conf`

And then update fontconfig:

`# fc-cache && mkfontscale && mkfontdir`
Note: This may cause conflicts with XeTeX/XeLaTeX if the same fonts are (separately) available to both TeX and Fontconfig, i.e. if multiple copies of the same font are available on the search path.

## TeXLive Local Manager

texlive-localmanager-gitAUR is a utility which allows to conveniently manage a TeX Live installation on Arch Linux. See Usage for details.

## Install .sty files

TeX Live (and teTeX) uses its own directory indexes (files named `ls-R`), and you need to refresh them after you copy something into one of the TeX trees. Or TeX can not see them. Magic command:

`# mktexlsr`

or

`# texhash`

or

`# texconfig[-sys] rehash`

A command line program to search through these indexes is

```kpsewhich
```

Hence you can check that TeX can find a particular file by running

```kpsewhich <filename.sty>
```

The output should be the full path to that file.

Alternatively, sty files that are intended only for a particular user should go in the `~/texmf/` tree. For instance, the latex package wrapfig consists of the file `wrapfig.sty` and would go in `~/texmf/tex/latex/wrapfig/wrapfig.sty`. There is no need to run `mktexlsr` or equivalent because `~/texmf` is searched every time tex is run.

### Manual Installation

Normally, new .sty files go in `/usr/share/texmf-dist/tex/latex/<package name>/*`. Create this directory if you do not have it. This directory will automatically be searched when *tex is executed. Further discussion can be found here: https://bbs.archlinux.org/viewtopic.php?id=85757

### Using PKGBUILDs

To install a LaTeX package on a global level, you should use a PKGBUILD for the sake of simplifying maintenance. Examples can be found in the AUR, e.g. texlive-ganttAUR.

## Updating babelbib language definitions

If you have the very specific problem of babelbib not having the latest language definitions that you need, and you do not want to recompile everything, you can get them manually from https://www.tug.org/texlive/devsrc/Master/texmf-dist/tex/latex/babelbib/ and put them in `/usr/share/texmf-dist/tex/latex/babelbib/`. For example:

```# cd /usr/share/texmf-dist/tex/latex/babelbib/
# wget https://www.tug.org/texlive/devsrc/Master/texmf-dist/tex/latex/babelbib/romanian.bdf
# wget [...all-other-language-files...]
# wget https://www.tug.org/texlive/devsrc/Master/texmf-dist/tex/latex/babelbib/babelbib.sty
```

Afterwards, you need to run `texhash` to update the TeX database:

```# texhash
```
