[02:21:43] <cradek> wow, that IS awesome
[02:22:14] <cradek> if it eventually ends up on the CNC menu on all our (future) installs that would be the greatest thing
[02:23:11] <cradek> hm, github doesn't want to load for me tonight
[02:24:20] <skunkworks_> cradek, it can be used as an input filter in axis

[13:46:30] <cradek> seb_kuzminsky: trying to build
https://github.com/SebKuzminsky/f-engrave on wheezy, I see that it build-depends dh-python which wants to pull in python3, but it appears that f-engrave is a python2 program. is this a normal thing you expect?

[15:03:46] <seb_kuzminsky> cradek: i was not expecting that
[15:03:54] <seb_kuzminsky> i only tried it on jessie
[15:04:22] <seb_kuzminsky> i'll see about fixing it for wheezy (it's easy to switch out the distro, just point pbuilder at another debootstrap tarball)
[15:04:41] <cradek> well I have no reason to believe it wouldn't build and work
[15:05:00] <cradek> I'm only asking about the distastefulness of requiring python3 to build a non-python3 program
[15:05:13] <cradek> I didn't actually (install dh-python and) try it
[15:05:24] <seb_kuzminsky> aha
[15:05:50] <seb_kuzminsky> yeha, dh-python attempts to be everything to everyone, which is not unreasonable, but a bit superfluous in this case probably
[15:07:51] <seb_kuzminsky> the only wonkiness i found with f-engrave is that you can't point it at /usr/share/fonts/truetype and access all fonts
[15:08:03] <seb_kuzminsky> because it doesn't recurse, it only looks in the directory you tell it
[15:09:00] <seb_kuzminsky> ... so if someone was looking for a python project, that'd probably be an easy one to get into
[15:15:06] <seb_kuzminsky> cradek: i think maybe dh-python.deb is *just* for python3 and python2 doesnt need it

[15:28:15] <cradek> awesome
[15:29:14] <cradek> hm I also need the upstream tarball...
[15:30:12] <cradek> dpkg-source: error: can't build with source format '3.0 (quilt)': no upstream tarball found at ../f-engrave_1.58.orig.tar.{bz2,gz,lzma,xz}
[15:32:36] <cradek> avoiding that, I get: /usr/bin/install: cannot create regular file `/usr/local/bin/ttf2cxf_stream': Permission denied
[15:32:53] -!- emc has quit [Remote host closed the connection]
[15:34:56] <cradek> argh, it doesn't recognize .zip as the upstream source
[15:36:49] <cradek> aha
[15:37:21] <cradek> once I repackage the upstream as orig.tar.gz, quilt works, and it fixes everything
[15:39:24] <seb_kuzminsky> great
[15:39:51] <seb_kuzminsky> i put the repackaged orig tarball here, in case anyone wants it:
http://highlab.com/~seb/linuxcnc/f-engrave_1.58.orig.tar.bz2
[15:41:02] <seb_kuzminsky> i wonder if i should make it into a native package
[15:41:16] <seb_kuzminsky> instead of quilt-style, which requires an orig tarball
[15:43:22] <cradek> http://timeguy.com/cradek-files/emc/fengrave-package-vcarve-r.png
[15:43:36] <cradek> package builds and runs on wheezy
[15:43:49] -!- emc [emc!~emc@198.45.191.246] has joined #linuxcnc-devel
[15:47:06] <cradek> the gcode even loads and runs
[15:47:58] <cradek> so awesome
[15:48:17] <cradek> also, the AXIS preview feature where you can select a line and then rotate around it is awesome
[15:49:26] <seb_kuzminsky> very cool :-)
[15:49:46] <cradek> our users are going to love this
[15:50:39] <cradek> have you talked to the author?
[15:51:57] <cradek> >From that information
[15:52:11] <seb_kuzminsky> i mailed the author yesterday but haven't heard back yet
[15:52:18] <cradek> interesting - the emc-users mails somehow get ^From_ mangled still
[15:52:43] <cradek> it's always a surprise whenever you think the past is over
[15:53:35] <seb_kuzminsky> the f-engrave website has a couple of ttf and cxf fonts on it, i wonder if they're redistributable
[15:53:51] <seb_kuzminsky> if so we should probably include them in the deb
[15:54:01] <seb_kuzminsky> (if they're not in some other fonts package in debian already)
[15:54:18] <skunkworks> huh - I didn't know axis rotated around the selected segment...
[15:54:26] <cradek> it's so nice
[15:54:37] <cradek> if only every program had navigation as good as AXIS's
[15:56:00] <cradek> hmm,
http://timeguy.com/cradek-files/emc/about-axis.png
[15:56:01] <seb_kuzminsky> i pushed some commits to the f-engrave github to make it into a native package, so no .orig tarball is needed
[15:56:12] <seb_kuzminsky> haha
[15:56:26] <cradek> ooh lemme try rebuilding
[15:56:58] <seb_kuzminsky> it now build-depends on tofrodos, since the f-engrave python file has dos line-endings
[15:57:39] <cradek> haha your 200-fromdos patch was ridiculous
[15:57:47] <seb_kuzminsky> it's interesting that the f-engrave author mentions awallin__ 's openvoronoi project
[15:58:02] <seb_kuzminsky> hrm yeah i was hoping no one would notice
[15:58:43] <cradek> but you didn't actually fromdos it in git?
[15:59:57] <cradek> yay, that builds much more easily now
[16:00:48] <seb_kuzminsky> nah, i do it at build-time now
[16:01:01] <seb_kuzminsky> makes it easier to rebase the debian packaging onto the next upstream release
[16:01:15] <seb_kuzminsky> it's in the top-level Makefile
[16:01:16] <cradek> good point
[16:01:34] <seb_kuzminsky> the old quilt way (and a similar commit in git) would have been a pain
[16:02:26] <cradek> and you remembered to build-dep tofrodos
[16:02:31] <cradek> wizard
[16:02:42] <seb_kuzminsky> i have this build system that was originally for making rtai kernels, but that grew into making debs of a bunch of useful packages (mesaflash, ttt, etc), it'll be easy to drop this f-engrave git repo into that system
[16:02:58] <seb_kuzminsky> https://github.com/SebKuzminsky/linux-rtai-build
[16:03:21] <seb_kuzminsky> then we can add those debs to the archive at wlo

[18:02:10] <cradek> I'm very sad to tell you that I think this package is undistributable because it contains both gpl-2-only and gpl-3+ code

[18:18:30] <mozmck> It would seem that the FSF has done their cause a bit of harm by making gpl-3 incompatible with gpl-2
[18:18:53] <cradek> it's sad but I'm very sure it was unavoidable
[18:19:24] <cradek> I wonder if the author would relicense f-engrave-158.py to be 2+ instead of 3+
[18:19:48] <mozmck> I don't know. It is certain that a lot of projects cannot change for similar reasons to linuxcnc.
[18:20:15] <cradek> I think this is one author who wrote one file
[18:20:33] <cradek> very different from our unknown number of authors over 20 years
[18:20:57] <mozmck> yes, that's what I'm referring to. I believe the linux kernel is that way as well
[18:21:04] <cradek> if not, we can absolutely make two packages, one that depends on the other - this is not a fatal problem
[18:21:29] <cradek> yep, linux kernel is the same way and even (slightly) older
[18:22:05] <cradek> linus explicitly rejects the idea of trusting an infinite number of unknown future licenses
[18:22:20] <cradek> which is really quite understandable if you ask me

[22:20:32] <seb_kuzminsky> cradek: scorch (the f-engrave author) says the gpl3+ license of f-engrave was inherited from the engrave-11 program on our wiki, which was the starting point for f-engrave
[22:20:42] <seb_kuzminsky> http://wiki.linuxcnc.org/uploads/engrave-11.py
[22:22:02] <seb_kuzminsky> he(?) has also integrated source code from other projects, all compatible (he claims) with gpl3+
[22:22:14] <seb_kuzminsky> and so he's declined the request to relicense it
[22:22:16] <seb_kuzminsky> shrug
[22:27:00] <andypugh> His code, his choice,
[22:34:36] <mozmck> Is it? If it is derived from gpl3+ licensed code, he doesn't really have a choice does he?
[22:37:19] <seb_kuzminsky> i think you're right, mozmck
[22:37:42] <seb_kuzminsky> he created a derived work from engrave-11.py, which is licensed gpl3+, so the derived work must match that
