File Files

The files node defines a group of files that all share the same attributes, including relative directory, default compiler flags and dependencies. The node can be used to define a set of header files on which other files can depend, or a set of source files to be compiled and included in a terget.

  • depend - Declare that all files in the group depend on another file or another file group. `xml <depend name="filename" /> <depend files="filesId" />` + name = If the named file changes then then all the files in the group need recompiling. + files = If any of the files in the named group changes then then all the files in the group need recompiling.

  • options - Name of file containing compiler flags. When the cache is not used, Options.txt helps detect when the options have changed, and therefore whether files need recompiling. `xml <options name="Options.txt" />`

  • config - Name of file to generate that contains the #defines that were active when code was compiled. `xml <config name="outfile.h" />`

  • tag - Add a default compiler flags tag too all files in group. See Tags.md. `xml <tag value="tag" />`

  • addTwice - When compiled to a library, add the library twice to the link line - once at the beginning and once at then end to satisfy linux selective linking. `xml <addTwice value="tue" />`

  • cache - Use compiler cache for files in group. See compile cache for more details. `xml <cache value="true" project="name" asLibrary="true" />` + project = name of project used to manage and group object files in the cache + asLibrary = link the objs into a .lib file, which can skip unneeded objs, but will also skip things that rely on static initializers to register handlers, so be careful.

  • include - Include an external file list `xml <include name="filename.xml" />`

  • section - Groups block of elements - usually ones that all respect the same if/unless condition. `xml <section name="id" /> </section>`

  • compilerflag - Add a compilerflag when compiling files in group. `xml <compilerflag name="name" value="value" /> <compilerflag value="value" />` + name, value = add 2 flags when compiling + value = add 1 flag when compiling

  • nvcc - This group is compiled with nvcc. `xml <nvcc />`

  • objprefix - An id prepended to generated obj name to allow alphabetical grouping of similar objs. `xml <objprefix value="prefix" />`

  • precompiledheader - Use a precompiledheader of given name when compiling group `xml <precompiledheader name="name" dir="directory" />` + name = the include used when precompiling these files (without the .h) + directory = the location of this file

eg, for #include <lib/Header.h>

+ name = "lib/Header"
+ directory = "${haxelib:somelib}/include"
  • file - Add file to group, with optional attributes `xml <file name="filename" tags="tag,tag1" filterout="define" embedName="embed" > <depend name="filename1" /> <depend name="filename2" /> </file>` + name = name of file - may be absolute or relative to files.dir + tags = optional override of group tags. See Tags.md. + filterout = allows files to be skipped at compile-time if the named define exists. This is useful when the define is set sometime after the file list is parsed. + depend name = filename of additional dependency + embed = causes the file to be embedded as a enxtern c++ 'const char *' string constant of the specified name
