# ConTeXt Standalone/Structure

Top Level:

• current: main files
• experimental: experimental luatex and other binaries - doesn't work at the moment

## current

### base

Base TeX and metapost files, stored as

```section/TDS
```

There are currently files for:

• tex - plain TeX
• metapost - plain metapost (including metaobj - for unknown reason - they were in Hans's distribution, sa I took them as well)
• xetex - XeTeX: only tex-text font mapping

Hans has asked me several times why there is tex/tex/something and metapost/metapost/something (instead of one metapost less). This is because that's the only way to split TeX and Metapost while still allowing one to use (an obscure example)

```rsync -av rsync://contextgarden.net'/minimals/current/base/xetex/ /minimals/current/base/metapost/' destination
```

leaving the plain TeX files on the server and not loosing TDS compliance. Also, once I add the documentation, there will be more than just metapost/metapost, but also metapost/doc.

One little problem: base metapost files are behind time compared to the binaries. Should anyone need newer files, feel free to complain and we will add them.

### bin

Binaries, stored as

```engine/platform/TDS
```

where platform can be mswin, linux, linux-64, osx-intel, osx-ppc, sun, and engine is

• context: stubs, mtxrun, luatools, texmfstart
• common: most not-so-fast-changing binaries from TeX Live
• luatex
• metapost
• pdftex
• xetex

Special:

• man: man pages
• mswin: rsync, unzip

### context

ConTeXt distributions, stored as

``` version/TDS
```

where version could be

• current
• beta (preferred one for testers, will default to current if not present)
• alpha (rarely released, will default to beta if not present)
• experimental (not to be used)
• YYY.MM.DD (but not all of them are available)

You can fetch a specific version with

```--context=version
```

in `mtx-update.lua`.

### fonts

Fonts will be reorganized!

Fonts, currently stored as

```type/TDS
```

where type is:

• common: to be used with both pdfTeX, LuaTeX and XeTeX (mostly math & some other fonts)
• old: tfm, enc, map files: only for pdftex
• new: opentype fonts: only for LuaTeX & XeTeX

### misc

A special one. Currently has:

• setuptex: to setup a distribution, usually needs to be put on the top of TeX trees hierarchy
• web2c: setup files (texmf.cnf) - may change location in future

### modules

Third-party modules, stored ass

```module/TDS
```

where the available modules are synced from http://modules.contextgarden.net. If you would like your module to be added, request it on the mailing list.

## Example installation (on Windows)

Here’s how I (Joel Salomon) am installing ConTeXt on my machine. It works for me; your mileage may vary.

First I created a root directory for the installation; I install “personal” programs under `%USERPROFILE%\Programs`, so I create the directory `USERPROFILE%\Programs\ConTeXt`. If you’re working from the command-line, you might want to set an environment variable for this, e.g.,

```set CONTEXTROOT=%USERPROFILE%\Programs\ConTeXt
```

—just be aware that if you’re setting the variables below in the Windows dialog box, you’ll have to expand all uses of `%CONTEXTROOT%` yourself. (A ‘portable apps’ version of ConTeXt would set those variables in the launcher/wrapper.) I’m going to phrase the rest of this section in terms of the command-line.

This effort is closely related to [GUI installer]; I hope this makes explicit all the installer does.

Note that my system has Ruby installed; I don’t yet understand how to include a minimal Ruby.

### Create the directories

Following the arrangement from mswincontext.zip and the ConTeXt Minimals’s download script, generate the following TDS trees, and add the binaries’ installation directory to the system path:

```cd %CONTEXTROOT%

mkdir texmf texmf-context texmf-extra texmf-fonts texmf-local texmf-mswin texmf-mswin\bin texmf-project texmf-var %TEMP%\texmf-cache

set PATH=%PATH%;%CONTEXTROOT%\texmf-mswin\bin;

set OSFONTDIR=%SystemRoot%\Fonts

set TEXMFMAIN=%CONTEXTROOT%\texmf
set TEXMFCACHE=%TEMP%\texmf-cache
set TEXMFCONTEXT=%CONTEXTROOT%\texmf-context
set TEXMFEXTRA=%CONTEXTROOT%\texmf-extra
set TEXMFFONTS=%CONTEXTROOT%\texmf-fonts
set TEXMFLOCAL=%CONTEXTROOT%\texmf-local
set TEXMFOS=%CONTEXTROOT%\texmf-mswin
set TEXMFPROJECT=%CONTEXTROOT%\texmf-project
set TEXMFVAR=%CONTEXTROOT%\texmf-var
set VARTEXMF=%CONTEXTROOT%\texmf-var
```
 TODO: Some of these might not be needed; will someone who knows which please edit this list? (See: To-Do List)

Also, tell the programs what directories have TDS trees, and where to look for configuration settings:

```set TEXMFCNF=%CONTEXTROOT%\texmf{-local,-context,}\web2c
set TEXMF={%TEXMFMAIN%,%TEXMFLOCAL%,%TEXMFCONTEXT%,%TEXMFOS%,%TEXMFPROJECT%,%TEXMFFONTS%,%TEXMFEXTRA%,%VARTEXMF%}
```

(As stated above, you may need to expand these, e.g., replace `%TEXMFMAIN%` with `%USERPROFILE%\Programs\ConTeXt\texmf`.

I’ve broken the `rsync` commands into multiple lines for readability, but you need everything on one line, space-separated. Note also that each TDS tree has its own `rsync` call; that lets me add the `--delete` option safely.

I need `rsync`, so I download it to the binaries directory, which I’ve already put on the path. Note that `rsync` runs under the Cygwin subsystem, so I need to set an environment variable telling it to play nicely with Windows’s ideas of file ownership. This variable doesn’t need to be permanently set (and if you run Cygwin, it probably shouldn’t be); set it temporarily before you run `rsync`. My system has `wget` installed so I’ll use that, but any method of downloading should work fine.

```set CYGWIN=nontsec

wget -P texmf-mswin\bin http://minimals.contextgarden.net/setup/mswin/bin/rsync.exe
wget -P texmf-mswin\bin http://minimals.contextgarden.net/setup/mswin/bin/cygwin1.dll
```

If I were using `mtx-update` to manage the install, I’d run

```rsync -rpztlv --exclude 'rsync.exe' --exclude 'cygwin1.dll' rsync://contextgarden.net/minimals/setup/mswin/bin/ texmf-mswin/bin
texlua texmf-mswin\bin\mtxrun.lua --verbose --script texmf-mswin\bin\mtx-update.lua --update --force --engine=all --texroot=%CONTEXTROOT%
```

but I’m going to try to exercise much finer control than `mtx-update` allows for. I did adapt the output of an `mtx-update` run (without `--force`) to generate the `rsync` calls below.

#### Base

Download the base TeX files, as mentioned above. I moved `web2c` here from the miscellanea section, so the tree is updated in a single run. Note that the `web2c` directory does not have a trailing ‘/’. That’s because it goes into a TDS tree, rather than containing (part of) one; omitting the ‘/’ gives us the directory `…/texmf/web2c`.

```rsync -rpztlv --stats contextgarden.net::'minimals/current/base/tex/
minimals/current/base/metapost/
minimals/current/base/xetex/
minimals/current/misc/web2c' texmf
```

#### Binaries

Download binaries for all engines, plus the specials, for the `mswin` platform. For a “legacy-free” installation, omitting the line with PDFTeX should work—but I haven’t tested it.

```rsync -rpztlv --stats contextgarden.net::'minimals/current/bin/context/mswin/
minimals/current/bin/common/mswin/
minimals/current/bin/metapost/mswin/
minimals/current/bin/pdftex/mswin/
minimals/current/bin/xetex/mswin/
minimals/current/bin/luatex/mswin/
minimals/current/bin/man/' texmf-mswin
```

(Perhaps the `man` tree should be placed elsewhere; `texmf`, or maybe `texmf-extra`?)

#### ConTeXt

The more adventurous can replace `current` with `alpha`, `beta`, `experimental`, or `latest`.

```rsync -rpztlv --stats contextgarden.net::'minimals/current/context/current/
minimals/current/context/img/
minimals/current/context/config/' texmf-context
```

#### Fonts

Directory `other` is optional; `old` can perhaps be omitted for a “legacy-free” (i.e., PDFTeX-free) setup.

```rsync -rpztlv --stats contextgarden.net::'minimals/current/fonts/new/
minimals/current/fonts/common/
minimals/current/fonts/other/
minimals/current/fonts/old/' texmf-fonts
```

#### Miscellanea

On the initial run, you may want to download the `setuptex.*` files; I adapted the list of directory trees from there.

```rsync -rpztlv --stats contextgarden.net::minimals/current/misc/setuptex/ .
```

#### Extras

My guess is that `texmf-extra` is a good place to put the various modules mentioned above—at which point the installation can no longer be called “minimal”. The invocation would look something like this:

```rsync -rpztlv --stats contextgarden.net::'minimals/current/modules/f-urwgaramond/
minimals/current/modules/t-bnf/
minimals/current/modules/…/' texmf-extra
```

Include whatever modules you’d like.

#### Project

I have no idea what goes into `texmf-project`, nor where it comes from; I’m including this directory only because the installation scripts refer to it.

### Building the formats

The commands below were excerpted from a run of `texlua texmf-mswin\bin\mtxrun.lua --verbose --script texmf-mswin\bin\mtx-update.lua --make --engine=all --texroot=%CONTEXTROOT%`.

#### Kpathsea

PDFTeX and XeTeX use Kpathsea and its `ls-r` databases to find files. Also, I let `texexec`handle the generating of formats. I don’t know what the `--all` option does; I want a minimal (necessary and sufficient) set of formats, which I think this is:

```mktexlsr
texexec --make --all --pdftex metafun cont-en
texexec --make --all --xetex metafun cont-en
```

#### luaTeX

LuaTeX has its own databases, and its own way of generating formats:

```luatools --generate
luatools --ini --compile cont-en
```

### Updating

I haven’t tried this yet, but repeating the `rsync` calls for the Base, Binaries, ConTeXt, Fonts, and Extras trees, perhaps including the `--delete` option, followed by rebuilding the databases & formats, should work.
