| Summary | 0000644: List "pyxplot" as a dependency in the ppa | ||||
| Description | "pyxplot" Ship mod requires pyxplot ..... shouldn't it now be a dependency in the ppa?? | ||||

My opinion is that we should avoid mandatory dependencies as much as possible, specially a big one such as pyxplot (outside, of course, the unavoidable ones such as OCC). It is the responsability of the module to see if it's available and use it or not. For me it should be listed as "suggested"... |
|
|
OK, possibly you right, so long as it is in the suggested I guess that will do. But it will be a relative novice installing and using the PPA version, isn't it better therefore if it just installs everything needed so that FreeCAD just works? When I tried to use the function without PYXPLOT FreeCAD just opened up a new blank "drawing" page. Wouldn't it be better for it to pop up an error message telling the user to install pyxplot? But wouldn't it be easier to just added it as a dependency? |

Reminder sent to: Jose, could you have a look at this please? |

It's a 70Mb package, I don't think it's fair to force users who won't use the ship module to have it... But I think it would be nice indeed to warn users that they need to install that package if they try to use it. |
|
|
I have just ran into this issue. I understand it is a big dependency but I think the module should advise when the user tries to use the tool that it won't be able to plot (and how it can be solve...) |

pyxplot is outdated due to I'm developing a Plot module for FreeCAD using matplotlib (pyxplot is not present on windows). I requested at dev mail list for Windows installer maintainers incorporates matplotlib (and numpy, that is a dependency), but for the moment I haven't received answer. When Windows installer creators includes matplotlib (or no answer received for a lot of time) i will request Plot module integration at master branch (Plot module branch already includes CMake/Autoconf and Debian packages matplolib dependency stuff). For the moment I'm writting some documentation: https://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Plot_Module When Plot module was ready i will implement it at Ship module. I will send new request at forum! Thanks!!! |

In the Ubuntu repos I have only found python-matplotlib and python-numpy, is that it? It requires quite a lot of packages and I don't think it takes less space than pyxplot, but one dependency I don't like much is the Gtk+2 GUI library. Although it's probably installed by default on Gnome and Xfce systems, I don't know about KDE. http://packages.ubuntu.com/precise/python-matplotlib |

Yes. > It requires quite a lot of packages and I don't think it takes less space than pyxplot On my Ubuntu 12.04 test system it requires 20MB additional memory while for a pyxplot installation it wanted 700MB (!!!) more space. > but one dependency I don't like much is the Gtk+2 GUI library. Although it's probably installed by default on Gnome and Xfce systems, I don't know about KDE. If a KDE user has applications installed that do not depend on the KDE libs then the chance is high that GTK is installed, too. Sure, it's probably not the most elegant way but by far better than having the huge pyxplot stuff. |

@sanguinariojoe: matplotlib is available also for Windows and MacOSX https://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.1.1/ but in order to have this for Windows a new LibPack is required where we can put this into. Just deploying it with an MSI installer without putting it to the LibPack doesn't make sense. Since creating a new LibPack doesn't happen overnight you should implement your Ship module that a matplotlib package is only mandatory for the plotting and all other commands are able to work without it. |

OK! Topic closed?? |

Not until the dependency is actually added to the ppa! After all this is what the bug description says. ;-) Actually it would be a "recommend" or even "suggested" instead of a dependency. I can do it at any time, but I'm wondering if we should not wait for when the Windows LibPack gets updated, and do the ppa at the same time. In FreeCAD Werner added a Dependency graph tool that needs a specific package to work. When I first tried this feature a dialog opened to tell me what to install. Could you do the same for your plotting utility? |

> Not until the dependency is actually added to the ppa! I don't see pyxplot as package dependency. I'm looking for pyxplot on Debian packaging stuff, on daily built debian package, on autotools stuff, on cmake stuff and on windows installer stuff, but i can't find any reference to pyxplot. I requested a merge of my plot module that adds matplotlib as suggestion when autotools or cmake is used (printing a warning if not found), and as recommend package at debian packaging stuff. For windows users for the moment a warning is printed on FreeCAD start saying that Plot module is not available. The point is that I don't know if I may add matplotlib (and all subdependencies) as build-dependency too, due to cmake will not install the module if matplotlib is not installed. (I didn't think on this, thanks!) Maybe cmake can be forced to install module although matplotlib can't be found... What do you think? > In FreeCAD Werner added a Dependency graph tool that needs a specific package to work. When I first tried this feature a dialog opened to tell me what to install. Could you do the same for your plotting utility? I'm not sure to understand. Is a FreeCAD tool that when is being executed and found dependencies missed shows you what do you need? Seems nice! Where can i find the source code? Nevertheless, the topic around pyxplot seems closed, or at least moved to matplotlib, no? |

Ok, I'm closing this one then, reopen if needed... |
