How to write a definition with variants?












3















In TeX I can define, say



def1#1 is #2.{#1 & is & #2.\}



and



def2#1 has #2.{#1 & has & #2.\}



with an easy usage:
1 Jim Jones is a fictional character.
and
2 Tim Smith has two brothers.



This gives three columns of a tabular: Jim Jones, is, a fictional character. Similarly in the second case.



Can I write a definition depending on, in this case, is/has so I can write



3 Jim Jones is a fictional character.
and
3 Tim Smith has two brothers.



obtaing the previous results?



Solutions using Lua or expl3 are OK, but I hope that a pure TeX one is also possible.






macros plain-tex

  • At the TeX level for any def you can have only one parameter text (the #1 is #2. and #1 has #2. in your 1 and 2 respectively).

    @marmot I am not sure what you mean by "teach" in this context. However, look also at my tabstackengine package, which uses listofitems for parsing. It can digest matrices and remember all the cell content for future use.

flock() on closed filehandle LOCK_FILE at /usr/bin/apt-mirror

Image
0 I recently upgraded an Ubuntu 16.04 virtual machine to 18.04. I regularly use this VM to run apt-mirror at school on their high-speed internet, then rsync these files to my rack-mount server at home for updating multiple computers at home without wasting the tiny amount of bandwidth I have there. Since updating I can't get apt-mirror to run on my VM. It keeps giving the error: flock() on closed filehandle LOCK_FILE at /usr/bin/apt-mirror line 214 immediately followed by: apt-mirror is already running, exiting at /usr/bin/apt-mirror line 217 apt-mirror is NOT running, and does not have a cron job. I've tried rebooting, and even looked for the old-style lockfile to delete, but I guess that method is no longer used. Is there some way to force unlock this so I can run apt-mirror? UPDATE: So...
