The solution, and the source code used in this recipe, was kindly provided by Christopher Lenz (aka cmlenz). 4 6 5 7 When working with a relatively large set of xml sources that make use of XIncludes there is a common question that comes in two forms: … … 8 10 * What files '''were''' included by a particular source ? 9 11 10 This recipe seeks to address the first sense as far as is possible. [wiki: MarkupRecipes/SconsXIncludeScanner Implicit dependencies with scons] could be used as a starting point for answering the second.12 This recipe seeks to address the first sense as far as is possible.

The latter makes it impossible to know for certain "before the show", which files '''will''' be included. Conditional includes that depend on static state could be determined before the show. This is, however, far from trivial. 79 81 80 Integrating Markup, or anything like it, into a build system is a typical scenario that prompts these questions. Typically you will want automatic dependencies, and reliable, but minimal, rebuilds in the event that any of your source files are changed.82 Integrating Genshi, or anything like it, into a build system is a typical scenario that prompts these questions. Typically you will want automatic dependencies, and reliable, but minimal, rebuilds in the event that any of your source files are changed. 81 83 82 84 For build system dependencies the consequence of false positives is often acceptable. The consequence being more sources are rebuilt than strictly necessary. And, answering the latter form of the question, "what files '''were''' included" is usually sufficient for ensuring re-builds are both minimal and correct. 83 85 84 86 ---- 87 See also GenshiRecipes, [wiki:GenshiRecipes/SconsXIncludeScanner]
