| Summary | 0003986: LIST(FILTER <list> <regex> [<regex> ...] [OUTPUT_VARIABLE <variable>]) | ||||||||
| Description | SYNOPSIS: LIST(FILTER <list> <regex> [<regex> ...] [OUTPUT_VARIABLE <variable>]) FILTER removes items from <list> which do not match any of the specified regular expressions. An optional argument OUTPUT_VARIABLE specifies a variable in which to store the matched items instead of updating <list>. Thank you -- Tristan | ||||||||

What's the use case ? |
|
(0008633) Tristan Carel (reporter) 2007-08-23 16:09 |
Do you want an example of how to use it or me to explain how useful it can be? Here is an example to extract CPACK variables defined in environment: --------------------------------------- GET_CMAKE_PROPERTY(cpack_variables VARIABLES) LIST(FILTER cpack_variables "^CPACK.+") --------------------------------------- or by using the optional parameter: --------------------------------------- GET_CMAKE_PROPERTY(variables VARIABLES) LIST(FILTER variables "^CPACK.+" OUTPUT_VARIABLE cpack_variables) --------------------------------------- which is much more concise and lisible than doing is manually. Users don't have to filter lists manually with FOREACH statement anymore, which can be source of many errors. With several criteria, the code becomes as huge as repetitive. The optional argument avoid user to make a copy before using the command in case he wants to keep the previous content. Hope this answer the question |

There are so many things which can be done with lists. This sounds a bit very special. Can't this be wrapped in a macro ? |

I wish list filtering to be a `real' CMake command as I believe this is a common operation. Write a macro, and add it to the wiki (in http://cmake.org/WIKI/CMakeMacroListOperations [^]) is quiet useless because the rookie CMake user doesn't know about this page. Maybe the solution would be to ease accessibility of this wiki page by adding the url in the official LIST documentation. Also this would promote user contributions. |

I don't feel like working on this, maybe somebody else picks it up. |

The "backlog" status is intended to be used for this. Alex |

I'm about to submit a patch for this but if it's decided that using a macro would be more appropriate then I've uploaded a sample macro here that will do the same thing. |
