| # Get ready for the ugly... |
| # |
| # - We have to nest our variables dictionaries multiple levels deep, so that |
| # this and other gyp files can rely on previously-set variable values in |
| # their 'variables': { 'conditions': [] } clauses. |
| # |
| # Example 1: |
| # Within this file, we use the value of variable 'skia_os' to set the |
| # value of variable 'os_posix', so 'skia_os' must be defined within a |
| # "more inner" (enclosed) scope than 'os_posix'. |
| # |
| # Example 2: |
| # http://src.chromium.org/viewvc/chrome/trunk/src/third_party/libjpeg/libjpeg.gyp?revision=102306 , |
| # which we currently import into our build, uses the value of 'os_posix' |
| # within the 'conditions' list in its 'variables' dict. |
| # In order for that to work, it needs the value of 'os_posix' to have been |
| # set within a "more inner" (enclosed) scope than its own 'variables' dict. |
| # |
| # - On the other hand, key/value pairs of a given 'variable' dict are only |
| # inherited by: |
| # 1. directly enclosing 'variable' dicts, and |
| # 2. "sibling" 'variable' dicts (which, I guess, are combined into a single |
| # 'variable' dict during gyp processing) |
| # and NOT inherited by "uncles" (siblings of directly enclosing 'variable' |
| # dicts), so we have to re-define every variable at every enclosure level |
| # within our ridiculous matryoshka doll of 'variable' dicts. That's why |
| # we have variable definitions like this: 'skia_os%': '<(skia_os)', |
| # |
| # See http://src.chromium.org/viewvc/chrome/trunk/src/build/common.gypi?revision=127004 , |
| # which deals with these same constraints in a similar manner. |
