[Emc-users] PROGRAM_PREFIX with spaces
Just wanted to drop a note to the to the group so that other's don't have to troubleshoot this maybe as much as I have. Turns out it might not be a great idea to put spaces in the directories that will go in your program path. It prevents custom M Codes from running from that directory and they seem to fail silently. Or if they don't fail silently, there doesn't seem to be any warning about it that I could find. Removed the space from my "NC Files" directory to NCFiles and updated PROGRAM_PREFIX and now my custom m-codes work. Everything else seems to work regarding that program prefix, I could open files, etc. Should I have escaped that space in the config file? If so what are the escape characters valid for the ini file? -Dave ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] PROGRAM_PREFIX
Erik, Thanks for the tip, but ultimately that has the same problem. For now I will just change the file attributes to require a sudo to edit or delete subroutines. The main purpose was to put them some place where they would not get accidentally deleted if someone was over zealous in cleaning up the nc_files folder. Thanks, Eric Until LinuxCNC supports separate directories directly, there is a workaround for both these use cases. Simply put the subroutine or other files in any desired directory, then place a link to each file in the $PROGRAM_PREFIX directory. e.g. for the latter use case: $ ln /home/emcuser/emc2/subroutines/mysub001.ngc /home/emcuser/emc2/nc_files (That's one line, but your mail client has probably wrapped it.) That hard link makes the file appear equally in both directories, though only one copy exists on disk. If one link is deleted, the one copy will still be in the other. If the two directories are on separate devices, you'll need a symlink instead, i.e. add -s after the ln. That link will remain afterwards, if the file it points to is deleted, and so is a little more work to maintain in that case. Hopefully there's something new in the above, for Lars or Eric. At least it is a way to do what they want, for now. The $PROGRAM_PREFIX directory is now only a funnel connecting to a thousand file directories, if desired. -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] PROGRAM_PREFIX
Thanks Erik, funny thing that the same question popped up from both me and Eric. Your answer is clear and educational, as always. // Lars Hopefully there's something new in the above, for Lars or Eric. At least it is a way to do what they want, for now.

In the ini file (I tried testing on sim/axis.ini and sim/tkemc.ini) I have: PROGRAM_PREFIX = /home/emcuser/emc2/nc_files So under [RS274NGC] I entered: SUBROUTINE_PATH = /home/emcuser/emc2/subroutines And call it with: Oheadup CALL For example. If the subroutines (headup.ngc and headdown.ngc) are in nc_files, it works fine, but if I move them to subroutines, I get a file not found error either immediately under axis or when trying to run under tkemc.
