GNUrc is the GNU Remote Control software. That's the software that aids in the maintenance of your thermostats. For other projects see projects.
Status
v1.1 released, v2.0 under development.
Motivation
To seek operational efficiencies in air-conditioners thereby saving electricity and improving comfort.

Technical specification
The technical specification describes how the project works.
Directory structure
The software has the following directory structure starting in the base:
/
The base directory is /path/to/your/gnurc.
- .svn-ignore -- files for Subversion (svn) to ignore
- e.g.: $ svn propset svn:ignore -RF .svn-ignore .
- config.example.php -- an example config file
- config.php -- the production config file
- e.g.: $ cp config.example.php config.php; vim config.php
/dat
The /dat directory is for data files.
- lang.dat -- the language subtag registry
- lang.ser -- the serialized PHP data-structure of the processed lang.dat file.
/etc
The /etc directory is for miscellaneous scripts.
- download-language-data.sh -- downloads the lang.dat file
/etc/dbscripts
The /etc/dbscripts directory is an svn:externals for the database scripts:
svn://svn.sv.gnu.org/remotecontrol/branches/development/dbscripts
- .svn-ignore -- files for Subversion (svn) to ignore
- .svn-ignore.sh -- a script to apply the svn-ignore settings.
- README.md -- the README file for the dbscripts.
- gnurc-db.sql -- a script to create a "gnurc" database.
- gnurc-schema.sql -- a script to apply the GNUrc schema to the 'current' database.
- gnurc-data.sql -- a script to insert default/global data.
- gnurc-test.sql -- a script to load test data.
- make-db.sh -- a script to create/upgrade a GNUrc database.
/src
The /src directory is for most of the source code.
- include.php -- the main include file for loading the GNUrc software components.
- test.php -- the main include file for use by PHPUnit unit tests.
/src/1-lib
The /src/1-lib directory contains function modules.
- 01-api.php -- an API for singletons and helper methods.
- 02-constants.php -- constants definitions.
- 20-array.php -- functions for working with arrays.
- 25-types.php -- functions for determining data types.
- 29-conversion.php -- functions for converting values.
- 30-formatting.php -- functions for formatting data.
- 35-validation.php -- functions for validating data.
- 37-defaults.php -- default settings.
- 40-late-constants.php -- late message and error definitions.
- 45-intl.php -- i18n helper functions/API.
- 55-calc.php -- functions for calculating.
- 60-html.php -- functions for working with HTML.
- 65-http.php -- functions for working with HTTP.
- 70-comparison.php -- comparison functions.
- 75-logic.php -- miscellaneous program logic.
- 80-datetime.php -- functions for working with dates and times.
- 98-handlers.php -- functions for error and exception handling.
- 99-screen.php -- global program logic.
/src/2-obj
The /src/2-obj directory contains PHP classes used by GNUrc that do not fit in another category.
- GrcDataPage.php -- represents and manipulates pagination settings.
- GrcDataSort.php -- represents and manipulates sorting settings.
- GrcError.php -- the API for declaring and raising software errors.
- GrcHtmlComposite.php -- an object to contain a list of HTML elements.
- GrcHtmlElement.php -- a class to model a HTML element. The global arrays in this file describe the various support for HTML by HTML4, XHTML and HTML5.
- GrcHtmlView4.php -- a class for rendering HTML 4.
- GrcHtmlView5.php -- a class for rendering HTML 5.
- GrcHtmlViewX.php -- a class for rendering XHTML.
- GrcIntl.php -- a class to support an internationalization (i18n) API.
- GrcListShuffler.php -- an object for shuffling a list, i.e. remove/first/previous/next/last.
- GrcMessage.php -- a class for declaring system messages (and aiding their translation).
- GrcPageLinks.php -- a class for modelling page links, e.g. first/last/next/previous/size=N/etc.
- GrcTableView.php -- a class for rendering tabular data as HTML.
- GrcUrl.php -- an API for modelling URLs.
- GrcValidation.php -- an API for data validation.
Managing errors
The error management subsystem is comprised of the /src/2-obj/GrcError.php class and the 'err' and 'Error' functions in /src/1-lib/01-api.php 01-api.php.
Errors are managed in to modes. First they are 'declared' and second they are 'raised'.
Declaring error numbers
To declare a possible error call the err()->define function. The first argument is the name of the error known as the error const. The error const has 6 parts separated by double-underscore (__):
- 'ERROR'
- type (e.g. 'LIB', 'OBJ', etc.)
- module/class (e.g. 'API', 'VALIDATION')
- function name
- variable name
- state (e.g. 'NOT_NULL', 'INVALID')
The second argument is the error message. The error messages will be translated if necessary and can include variables using the '%variable%' notation of the i18n subsystem.
Raising particular errors
After you have declared an error like this:
err()->define( 'ERROR__LIB__EXAMPLE', 'An error with %param% occurred.' );
you can raise it like this:
throw Error( ERROR__LIB__EXAMPLE, 'param', 'value', intl_context, previous_exception );
where intl_context is an i18n translation context and previous_exception is a previous exception if any.
Software layers
The GNUrc software is layered:
modules | /src/1-lib | |
objects | /src/2-obj | |
DAL | /src/3-dal | |
ORM | /src/4-orm | |
BOM | /src/5-bom | |
views | /src/6-view | |
controllers | /web |
Each level depends on (up to) all of the previous levels. So controllers use views, BOM, ORM, DAL, objects, and modules. Views use BOM, ORM, DAL, objects, and modules. The BOM uses the ORM, DAL, objects, and modules. And so on. Generally controllers should call on the services of the BOM rather than calling on the services of the DAL directly, so the BOM encapsulates business logic and mediates it into the DAL. If higher layers can encapsulate functionality in lower layers that is a good thing to do.
