restindex
crumb: Command Line
page-description:
The different command line options for **rest2web**. This includes
passing *uservalues* for use in your pages and templates.

======================
Command Line Options
======================
--------------------------------------------
Configuring Rest2web from the Command Line
--------------------------------------------
.. contents::
Introduction
============
Most **rest2web** configuration is done through the config file. It is
generally easier to edit a single text file than to have to remember lots of
arcane command line options. {sm;:-)}
There are several things you can control from the command line. These include :
* The `Config File <config_file.html>`_
* The verbosity level (how much information rest2web outputs as it runs
* Override the template file
* Go into force mode
* Specify global `uservalues <reference/uservalues.html>`_
Basic Usage
===========
If you type ``r2w.py --help`` at the command line, this is the message it
*should* print :
::
usage: r2w.py [options] config_file
options:
--version show program's version number and exit
-h, --help show this help message and exit
-v Verbose output (default).
-a Display warnings & actions only.
-w Display warnings only.
-t TEMPLATE, --template-file=TEMPLATE
Specify a template file. (Overrides first template.)
-u USERVALUES, --uservalues=USERVALUES
Global uservalues for the site, in the form
"name=value".
-f, --force Force site without indexes, restindexes or template.
-n, --nopause Do not pause after processing (overrides setting in config file).
-s, --skiperrors Skip errors (continue processing).
.. note::
Command line options are processed using `optparse <http://docs.python.org/lib/module-optparse.html>`_.
This only comes with Python 2.3 and more recent. On Python 2.2 you will
only be able to pass the config file at the command line.
The Config File
===============
If you run ``r2w.py`` *without* any command line options, it looks for a file
called ``r2w.ini`` in the current working directory.
Alternatively you can specify a `config file`_ as the last argument to ``r2w.py``.
Verbosity Level
===============
By default rest2web outputs a lot of information about what it does. This
includes which directories and files it is processing, as well any errors
raised along the way.
This may be too much information. There are three different verbosity levels :
* ``-v`` - Verbose, the default level. Information, actions and errors.
* ``-a`` - Action level. Actions and errors only.
* ``-w`` - Warning level. Warnings only.
Template File
=============
rest2web uses template files to generate the output pages. See `Templating <templating.html>`_
for the details of this.
Often you will only use a single template, specified in the `restindex <restindex.shtml>`_
of your top level index page. Sometimes you may want to use alternative templates
for the same site. For example one for the online version and one for the
distributed documentation.
You can override the top level template from the command line, using either :
``r2w.py -t path/to/template.txt``
``r2w.py --template-file=path/to/template.txt``
Uservalues
==========
`The Uservalues <reference/uservalues.html>`_ are a way of providing values to
use in your content and templates. They can be useful for multiple translations,
or for values that you want to specify at the time you build your site.
You can specify uservalues in the restindex of each page. You can also specify
*global* uservalues (available in every page) in the config file, or at the
command line.
If you specify the same values in your config file *and* at the command line,
the command line takes higher priority.
A uservalue needs a name (this is how you refer to it in pages/templates) and
a value. The name and value should be separated by an equals sign.
This means that you can specify uservalues at the command line using either :
``r2w.py -u "name=value"``
``r2w.py --uservalues="name=value"``
The double quotes are optional, but useful if the value has spaces.
Uservalues in pages will override global uservalues specified in either the
config file or at the command line.
Force Mode
==========
`force mode <force_mode.html>`__ allows you to build websites without specifying
a template, providing indexes, or having restindexes in the ReST documents that
form your pages.
You can supply any of these that you want, but where they are missing rest2web
will supply defaults.
To switch force mode onfrom the command line, use :
``r2w.py -f``
``r2w.py --force``
No Pause
========
This overrides the 'pause' option in the config file, and forces 'r2w.py' to
*not pause* after running.
skiperrors
==========
This option determines how rest2web will handle exceptions (like our old friend ``UnicodeDecodeError``) that happen when processing pages.
If set, rest2web will display the error and move to the next file. The default is off.
.. note::
If an error occurs whilst trying to process an index file, it will have to skip building the directory.
This feature is still 'experimental' and may need refining.
