Scripted makefile generator reference

This chapter contains description of functions and classes WinGDB adds to Lua for generating build files. Before starting wrtiting scripts, you can familiarize yourself with Lua syntax by reading this section. Full language manual is contained here.

Classes

The script language is object-oriented. Each variable can have a scalar type (integer, boolean or string) or a class type. In Lua you do not specify type of variable explicitly -- it is determined from the expression type.

Thich section describes various classes that WinGDB makefile generator adds to Lua. There are several categories of the classes, listed in subsections below.

Utility classes

VSUtils class is the class of the root object used to access Visual Studio functionality. There is one global instance of VSUtils, named just vs. It offers the means to access project hierarchy, diagnostic functions (printing to Visual Studio console) and path manipulation functions.

Regex class offers regular expression matching for strings.

Core project model classes

Those classes provide access to essential bits of Visual Studio project model. They are likely to be used in all of makefile-generating scripts.

VSSolution provides access to Visual Studio solution, its properties and contained projects.

VSProject represents a Visual Studio project, with extended support for Visual C++ projects.

VSProjectItem represents an item inside a Visual Studio project, typically a file or folder.

VSProjects is a collection of projects.

VSProjectItems is a collection of project items.

Additional project model classes

Those classes provide additional access to Visual Studio project model, but are not frequently used.

VSConfigurationManager: access to DTE ConfigurationManager object.

VSConfigurations: access to DTE Configurations collection.

VSConfiguration: access to DTE Configuration object.

VSOutputGroups: access to DTE OutputGroups collection.

VSOutputGroup: access to DTE OutputGroup object.

VSProperties: access to DTE Properties collection.

VSProperty: access to DTE Property object.

Method reference

All WinGDB-specific functions called from scripts are methods. Particularly, some "global" functions are methods of the VSUtils class, which has a single instance named vs. In all cases, use the : Lua operator to access the methods.

Methods are presented in C-like syntax. Argument and return types are either references to classes, or scalar types. In the latter case, bool, int and string represent standard Lua boolean, integer and string types. The strings type is standard lua array (a table indexed with 1-based numbers) containing strings.

Some of methods returning classes may return nil value, however it is expected only in error condition and should not normally occur. It might be reasonable to test returned class references against nil however, if you want absolute robustness.

If argument name is presented inside square brackets (e.g. [cfgName]), then it is optional. You may omit the argument, and WinGDB will assume default value (e.g. currently selected configuration).

Some collection classes have a method called item. It returns the item having specified index. Note that the index in these item is zero based, like in C/C++ and not like in Lua tables (where indexes are 1-based).

Other method names are self-descriptive, so the method purpose is not repeated explicitly. Many methods of classes VSProject and VSProjectItem return values of project (or file) properties, specific to Visual Studio C/C++ projects. These properties have CL or LN letters in names, denoting a compiler or linker property. The WG tag denotes a WinGDB-specific property, configured on WinGDB property page.

The VSUtils class has a method named evaluate. This method allows to evaluate all variables ($(name) constructs) within given string. You must specify project and configuration name, as it is important to determine the context of the evaluation.

The filter argument (in getProjectSources) accepts a list of file name wildcards separated by semicolons, e.g. *.c;*.cpp.

Example script

This is a simple example of a generator script. It is much simplified generator of GNU makefiles. The script shows the following aspects of writing generators in Lua:

• Use [[ ... ]] Lua construct to embed file templates.
• Use standard string.gsub Lua construct to replace values in the template.
• Use standard Lua io library to write the resulting file.
• Use WinGDB provided classes and methods to extract data from Visual Studio project.
