Instalação
----------

Python Package Index (recomendado):

```bash
pip install packtools
```

Pip + git (versão de desenvolvimento):

```bash
pip install -e git+git://github.com/scieloorg/packtools.git#egg=packtools
```

Repositório de códigos (versão de desenvolvimento):

```bash
git clone https://github.com/scieloorg/packtools.git
cd packtools
python setup.py install
```


Configuração do Catálogo XML
----------------------------

Um Catálogo XML é um mecanismo de *lookup* que pode ser utilizado para evitar que requisições de
rede sejam realizadas para carregar DTDs externas.

Por questões de desempenho e segurança, as instâncias de `stylechecker.XML` não realizam
conexões de rede, portanto é extremamente recomendável que seja configurado um Catálogo XML,
que traduz ids públicos para uris de arquivos locais.

O `packtools` já apresenta um catálogo padrão, que para ser utilizado basta definir a
variável de ambiente `XML_CATALOG_FILES` com o caminho absoluto para
`packtools/catalogs/scielo-publishing-schema.xml`.

Utilitário `stylechecker`
-------------------------

Após a instalação, o programa `stylechecker` deverá estar disponível no seu emulador de terminal.
Esse programa realiza a validação de um determinado XML no formato SPS contra a DTD, e
apresenta uma lista dos erros encontrados. Também é possível *anotar* os erros encontrados em uma
cópia do XML em validação, por meio do argumento opcional `--annotated`.

O utilitário `stylechecker` tenta carregar a DTD externa, especificada na declaração DOCTYPE do
XML. Para evitar esse comportamento, utilize a opção `--nonetwork`.

A função *ajuda* pode ser utilizada com a opção `-h`, conforme o exemplo:

```bash
$ stylechecker -h
usage: stylechecker [-h] [--annotated | --raw] [--nonetwork]
[--assetsdir ASSETSDIR] [--version] [--loglevel LOGLEVEL]
[--nocolors] [--extrasch EXTRASCH]
[XML [XML ...]]

SciELO PS stylechecker command line utility.

positional arguments:
XML filesystem path or URL to the XML

optional arguments:
-h, --help show this help message and exit
--annotated reproduces the XML with notes at elements that have
errors
--raw each result is encoded as json, without any
formatting, and written to stdout in a single line.
--nonetwork prevents the retrieval of the DTD through the network
--assetsdir ASSETSDIR
lookup, at the given directory, for each asset
referenced by the XML. current working directory will
be used by default.
--version show program's version number and exit
--loglevel LOGLEVEL
--nocolors prevents the output from being colorized by ANSI
escape sequences
--extrasch EXTRASCH runs an extra validation using an external schematron
schema.

History
=======

0.8.1 (2015-09-03)
------------------

* Fixe some issues that would cause invalid sps-1.3 XMLs to be considered valid.


0.8.0 (2015-08-31)
------------------

* Minor refactoring to make possible for the XMLValidator to handle deprecated
versions of SciELO PS.
* Added basic support to SciELO PS 1.3.


0.7.6 (2015-07-08)
------------------

* Fixed bug that would cause empty mandatory elements to be valid.


0.7.5 (2015-07-03)
------------------

* Added feature to run the validation against an external schematron schema
[#55].
* stylechecker's `--loglevel` option accepts upper, lower or mixed case strings.
* stylechecker utility can read from stdin, so it can be a filter in unix
pipelines.
* Added `--raw` option to stylechecker.
* Fixed bug that would raise UnicodeDecodeError in the presence
of any non-ascii character in the path to the file (Python 2 on Windows only).


0.7.4 (2015-06-19)
------------------

* Fixed bug that would cause page counts to be reported as error when
pagination is identified with elocation-id [#51].
* Added support for creative commons IGO licenses (sps-1.2 only).
* Fixed bug that would cause funding-group validation to raise false positives.


0.7.3 (2015-05-18)
------------------

* Validating the minimum set of elements required for references of type
journal [http://git.io/vUSp6].
* Added validation of //aff/country/@country attributes for XMLs under
sps-1.2 spec.


0.7.2 (2015-04-30)
------------------

* Fixes a bug in which the occurrence of empty award-id,
fn[@fn-type="financial-disclosure"] or ack could lead stylechecker to crash.


0.7.1 (2015-04-29)
------------------

* Fixes a bug that report *page-count* as invalid when fpage or lpage values
are non-digit.
* Fixes a bug that mark as invalid XMLs containing use-licenses with
https scheme or missing trailing slashes.
* Changes the funding-group validation algorithm.
* Checking for funding-statement when fn[fn-type="financial-disclosure"] is
present.


0.7 (2015-03-13)
----------------

* Added SciELO PS 1.2 support.
* Added the apparent sourceline of the element raising validation errors
(stylechecker).
* Added the option *--nocolors* to prevent stylechecker output from being
colorized by ANSI escape sequences.
* stylechecker now prints log messages to stdout. The option *--loglevel*
should be used to define the log level. Options are: DEBUG, INFO, WARNING,
ERROR or CRITICAL.
* SciELO PS 1.2 schematron uses EXSLT querybinding.
* Better error handling while analyzing multiple XML files with stylechecker.


0.6.4 (2015-02-03)
------------------

* Fixes a bug that causes malfunctioning on stylechecker
while expanding wildcards on windows.
* Major semantic changes at *--assetsdir* options. Now it is always turned ON,
and the option is used to set the lookup basedir. By default,
the XML basedir is used.


0.6.3 (2015-02-02)
------------------

* stylechecker CLI utility overhaul:
* The basic output is now presented as JSON structure.
* The option *--assetsdir* lookups, in the given dir, for each asset referenced in
XML. The *--annotated* option now writes the output to a file. The
utility now takes more than one XML a time.
* *pygments*, if installed, will be used to display pretty JSON outputs.


0.6.2 (2015-01-23)
------------------

* Added method `XMLValidator.lookup_assets`.
* Added property `XMLValidator.assets`.
* Fixed minor issue that would cause //element-citation[@publication-type="report"]
to be reported as invalid.
* Fixed minor issue that would erroneously identify an element-citation element
as not being child of element ref.


0.6.1 (2014-11-28)
------------------

* Minor fix to implement changes from SciELO PS 1.1.1.


0.6 (2014-10-28)
----------------

* Python 3 support.
* Project-wide code refactoring.
* `packtools.__version__` attribute to get the package version.
* Distinction between classes of error with the attribute `StyleError.level`.


0.5 (2014-09-29)
----------------

* Basic implementation of XML style rules according to SciELO PS version 1.1.
* `stylechecker` and `packbuilder` console utilities.
* Major performance improvements on `XMLValidator` instantiation, when used
with long-running processes (9.5x).
