rfclint 0.5.3

Perform a set of checks on an RFC input file to check for errors.

Perform Validation checks on Internet-Drafts
============================================


There are a number of tasks that need to be performed when an Internet-Draft_ is
begin process to create an RFC_. This tool performs a subset of those actions.
The actions performed are:

- Validate the file is well formed XML and that it conforms to the XML2RFC Version 3
schema as defined in `RFC 7991`_.
- Verify that embedded XML stanzas are well formed.
- Verify that embedded ABNF is complete and well formed.
- Identify misspelled words.
- Detect duplicate words.

The tool can be used either in an interactive mode or in batch mode.

.. _Internet-Draft: https://en.wikipedia.org/wiki/Internet_Draft

.. _RFC 7991: https://tools.ietf.org/html/rfc7991

Usage
=====

rfclint accepts a single XML document as input and optionally outputs a modified version
of the document.

**Basic Usage**: ``rfclint [options] SOURCE``


**General Options**

General options for the program

================ | ========================= | ==================================================
Short | Long | Description
================ | ========================= | ==================================================
``-C`` | ``--clear-cache`` | purge the cache and exit
``-N`` | ``--no-network`` | don't use the network to resolve references
``-n`` | ``--no-rng`` | don't check against the RNG schema
``-q`` | ``--quiet`` | don't print anything
| ``--save-config`` | save configuration back to config file
``-v`` | ``--verbose`` | print extra information
``-V`` | ``--version`` | display the version number and exit
``-X`` | ``--no-xinclude`` | don't resolve xi:include elements

``-c DIRECTORY`` | ``--cache=DIRECTORY`` | specify the primary cache directory to write to
| ``--configfile=FILENAME`` | specify the configuration file to use
``-o FILENAME`` | ``--out=FILENAME`` | specify an output filename
``-r RNG`` | ``--rng=RNG`` | specify an alternate RNG file
| ``--extract=TYPE`` | extract all source code for the given type
================ | ========================= | ==================================================


**Spelling Options**

The following options affect how the spell checking is performed.

=============== | ============================ | ==================================================
Short | Long | Description
=============== | ============================ | ==================================================
| ``--no-dup-detection`` | don't perform duplicate detection
| ``--no-spell`` | don't perform spell checking on the source
| ``--no-suggest`` | don't provide suggestions for misspelled words
| ``--no-spell`` | provide suggestions for misspelled words (default)

| ``--color=TEXT`` | specify the color to use for word highlighting
| ``--dictionary=FILENAME`` | specify an additional dictionary to use
| ``--personal=FILENAME`` | specify the personal dictionary to use
| ``--spell-program=FILENAME`` | program to use for spell checking
| ``--spell-window=NUM`` | how many words to display as part of the context
=============== | ============================ | ==================================================

It is assumed that the spell checking program is aspell and that aspell is on the path.
For Windows systems, it additionally look in "C:\\Program Files (x86)\\Aspell\\bin" for the program.
If a different program is given, then it should be either an absolute path or on the path so that
it can be located.

When a misspelled word is located, a certain amount of context will be provided along with the file
and line number of the word. The spell-window parameter controls how many words are displayed with
up to that number of words being displayed before and after the misspelled word. The context window
is also restricted to the current paragraph. The color option allows for the misspelled word to
be highlighted, but it requires VT100 terminal emulation and thus may not always work well on Windows
systems. The color defaults to 'bright' on non-Windows systems and 'none' on Windows systems.
If the value of spell-window is 0, then no context will be displayed.

**ABNF Checking Options**

=============== | =========================== | ==================================================
Short | Long | Description
=============== | =========================== | ==================================================
| ``--no-abnf`` | don't perform abnf checking on the source

| ``--abnf-add-rules`` | ABNF file to include when checking
| ``--abnf-program=FILENAME`` | specify program to use for ABNF checking
=============== | =========================== | ==================================================

Configuration File
==================

rfclint keeps configuration information in a configuration file. By default the file is stored at

* On Windows: c:\\Users\\USER\\AppData\\Local\\rfclint\\IETF\\rfclint.cfg
* Otherwise: /home/USER/.local/share/rfclint/rfclint.cfg

The format of the configuration file is the standard INI file format.

**Spell Configuration**

* program - name of the spelling program to use - defaults to aspell
* window - number of words to display on each side of a misspelled word
* color - color to use to highlight the misspelled word
* suggest - Should suggested values be displayed? value is 0 or 1
* dictionaries - a comma separated list of dictionaries to include

**ABNF Configuration**

* program - name of the ABNF program to use - defaults to bap provided w/ rfclint (bap is only installed for systems identified as nt, darwin or linux*)
* addRules - name of file to be processed along with rules in the source

Dependencies
============

rfclint depends on the following packages:

* lxml_ *(>= 4.1.1)*
* requests_ *(>= 2.5.0)*
* `rfctools_common`_ *(>= 0.5.3)*

.. _lxml: http://lxml.de
