8:22 AM

@PauloCereda Yes, the result of the match is exactly as in my dream... or I'm still dreaming?

@PauloCereda But we risked the 3-3 before Fred killed us for the 4th time... Sigh...

Paulo Cereda

10:39 AM

@karlkoeller It was a good game for both, I guess. :)

Marco Daniel

@PauloCereda: Do you have a moment?

Paulo Cereda

@MarcoDaniel Always. :)

Marco Daniel

@PauloCereda Great ;-)

Ok then let me start

I am writing a new rule. However it seems that arara and I have a misunderstanding of expansion. Let's start with the following rule:

!config
# DVIPS rule for arara
# author: Marco Daniel
# requires arara 3.0+
identifier: dtx
name: dtx-compilation
commands:
#    - <arara> @{engine} @{action} @{draft} @{shell} @{synctex} @{options} "@{file}"
    - <arara> @{ isTrue( parameters.printindex , 'makeindex -s @{indexstyle} -o  "@{getBasename(file)}.@{indexoutput}" "@{getBasename(file)}.@{indexinput}"' , ) }
    - <arara> @{ isTrue( parameters.printchanges , "makeindex -s @{changesstyle} -o  @{getBasename(file)}.@{changesoutput} @{getBasename(file)}.@{changesinput}" , ) }

The header isn't correct -- I know ;-)

My issue is related to the second line

<arara> @{ isTrue( parameters.printindex , 'makeindex -s @{indexstyle} -o  "@{getBasename(file)}.@{indexoutput}" "@{getBasename(file)}.@{indexinput}"' , ) }

The tags @{indexstyle} and friends are not expanded.

Paulo Cereda

@MarcoDaniel hmmm I need to check.

@Brent.Longborough Oh my, I'm in a hurry today. :) Off to the mass I go. :)

Brent.Longborough

@PauloCereda Catch you later. I'm still in İstanbul

Paulo Cereda

1:28 PM

@Brent.Longborough ooh Istanbul! :)

I was in São Paulo this week, so I think the places were similar.

Marco Daniel

2:00 PM

@PauloCereda Unfortunately.

Paulo Cereda

@MarcoDaniel Yep. I think situation in Turkey is actually far worse than ours. :(

Ironically, the tear gas used by the Turkish police is provided by a Brazilian company.

egreg

@percusse What if the document isn't printed, but in electronic form? ;-)

Just send around PNG images?

I guess that cryptography is much better.

@egreg I think the optimal solution is not creating a document if one is too sensitive about copy pasting or OCR.

Paulo Cereda

Quack.

egreg

@PauloCereda Lazy day.

Paulo Cereda

@egreg Indeed. :) And a cold one! :)

Our cricket expert David might explain these results later on.

egreg

@PauloCereda Oh, no! The Unicorns lost again!

Paulo Cereda

@egreg Oh no! They are the cricket version of Íbis. :)

Íbis Sport Club

Íbis Sport Club, or Íbis as they are usually called, are a Brazilian football team from Paulista in Pernambuco state, founded on November 15, 1938. Their home stadium is the Municipal de Paulista. They play in black and red colors. Íbis are one of the founders of the Pernambuco Football Federation.Ibis is nicknamed and known in Brazil as being the worst team in the world.

Friends, I am on Debian now!

@PauloCereda Could you please tell me about best practices regarding having a python script executable from any directory by putting into the /usr/bin/?

Paulo Cereda

@kan Personally, I'd go with a PATH addition in your bashrc file or perhaps adding your executable in /usr/local/bin. :)

kan

@PauloCereda So, in this particular case, the executable depends on a different module, and there are a couple of data files too... so which method do you think is particularly appropriate?

David Carlisle

Our cricket expert David might explain these results later on.

@kan A viable option is to create a directory somewhere (say, in your home or /opt directory) and put everything inside it and then add a symbolic link to your executable in /usr/local/bin. :)

Oh my, look at teh Unicorns!

kan

@PauloCereda Wonderful! Thanks for the advice!

I'll do that!

@PauloCereda Are we sure that, if I put something inside /usr/local/bin, it will be accessible from any directory?

Paulo Cereda

7:46 PM

@kan Yes.

kan

@PauloCereda Danke!

Paulo Cereda

@kan Sauerkraut. :)

My German is terrible. :P

kan

@PauloCereda Sour Cabbage?!

Paulo Cereda

@kan I told you, my German is terrible. :)

Alan Munn

@kan Not really a good translation. Pickled cabbage might be a bit better. In English, the German word is used.

kan

7:49 PM

@AlanMunn :)

Alan Munn

@PauloCereda The correct response is 'Bitte'. (Which also means 'please', thus leading to an infinite loop.) :)

Paulo Cereda

@AlanMunn Ah ~~thanks~~ bitte. :)

kan

@PauloCereda So, I guess for installing texlive too, I can put it at /opt right?

Paulo Cereda

@kan Yes. :)

Just pay attention to path priority.

Alan Munn

@kan Not quite. Your response there should have been 'Danke'.

kan

7:52 PM

I am on Debian @PauloCereda, So, there is no default texlive!

Alan Munn

@kan Are you doing this on a Mac?

(I see not.)

Paulo Cereda

@kan I meant path priority in general.

egreg

@AlanMunn Which is the same as in Italian "Grazie" "Prego"

kan

@PauloCereda Will Debian insist on installing dependencies?

As in should I take @egreg's route to installing?

Alan Munn

@egreg Yes, how you guys ever stop the loop is quite amazing. :)

Paulo Cereda

7:58 PM

@kan Go with egreg's guide. Note that some apps that rely on TeX might go for dependencies as well.

kan

@PauloCereda OK!

Paulo Cereda

@AlanMunn And prego for us is nail. :P

egreg

@AlanMunn A: "Grazie" B: "Prego" A: "Non c'è di che" B: "Si figuri, è un piacere" …

Paulo Cereda

@AlanMunn:

From a South Park episode. :)

Canadians eh.

kan

I can't see youtube from Debian! :(

Neither can I see vimeo.

(well, browser: iceweasel)

Alan Munn

8:02 PM

@egreg :)

@PauloCereda ? I guess I don't watch enough South Park. I don't see what this has to do with Canadians.

Paulo Cereda

@AlanMunn For non-South Park'ers, the reference is obscure. :) This is from an episode called Canada on Strike, I guess. And these guys are Terrance and Phillip. :)

egreg

@AlanMunn However, the usage of "prego" in contexts similar to "please" is declining in favor of "per piacere" or "per favore"; (or nothing at all: also politeness is declining.

Alan Munn

@DavidCarlisle I upvoted every one of your comments in the meta question. Reminds me of the movie The Reader.

@egreg What's the etymology of 'prego'?

David Carlisle

@AlanMunn I thought it was just going to be a quick comment, but he kept coming back:-)

Alan Munn

@DavidCarlisle repeat until exhausted {But I fixed the grammar. But you changed the meaning.}

David Carlisle

8:12 PM

@AlanMunn It's like a user once who was upset that I fixed a tex document so it no longer produced errors. It took a couple of rounds of email before I finally understood that I'd made the errors go from the log but the document was no longer producing any output:-)

kan

@DavidCarlisle Haha! :)

egreg

@AlanMunn Is "anormal" good?

Alan Munn

@egreg No. abnormal, but I think for what is meant probably 'atypical'? or just 'not normal'.

egreg

According to Mel Brooks it should be "a…b… something… a…b…normal"

Alan Munn

@egreg @PauloCereda Oops!!!!

In the step where I ask which tex I get back nothing!!

@kan What does ls /usr/local/texlive/2013 produce?

@kan And what's PATH set to?

Alan Munn

@egreg I think @kan installed into /opt

kan

doc.html install-tl LICENSE.CTAN README readme-txt.dir release-texlive.txt texmfcnf.lua texmf-dist tlpkg

@egreg I am following your article, basically!

In the /opt, the directory texbin has been created.

egreg

@kan What about PATH?

kan

@egreg Hmm, I have PATH=/opt/texbin:${PATH} ??

egreg

9:49 PM

@kan Hmm, this is not good at all.

Paulo Cereda

@kan What's the output of $ ls /opt/texbin?

egreg

@kan Output of echo $PATH, please

kan

@egreg I am not sure what you're asking for...

egreg

@kan Type "echo $PATH" on the terminal (without the quotes)

And please $ cat /etc/profile

@kan no /opt/texbin in you PATH

Paulo Cereda

@DavidCarlisle neither is set in profile. :)

egreg

@kan There is no /opt/texbin. Did you put the instruction export PATH=/opt/texbin:$PATH in the file texlive.sh that you put in /etc/profile.d?

kan

@PauloCereda But, I did those... :( :(

egreg

@kan Did you logoff and login?

kan

9:53 PM

@egreg I did too... BTW, does it matter that this is Debian?

I can try logoff and login once again?

egreg

@kan Maybe. What's the output of "ls /etc/profile.d"?

Paulo Cereda

A long time ago, a file put inside profile.d had to have +x in order to be executed (Slackware for the win), but Fedora doesn't require it. Try # chmod +x /etc/profile.d/texlive.sh.

kan

@egreg bash_completion.sh texlive.sh

Paulo Cereda

@kan Please, ls -la /etc/profile.d

Ubuntu spoiled a generation of Linux newbies. :(

Damn, no x flag.

kan

@PauloCereda Sorry. I am still learning.

egreg

@PauloCereda No x flag for bash_completion.sh either.

Paulo Cereda

@kan No please, it wasn't for you! :) I meant that Ubuntu, instead of following Debian's guidelines, turned into a different thing.

egreg

@kan Try issuing "PATH=/opt/texbin:${PATH} which tex"

kan

@egreg /opt/texbin/tex

!!!!

egreg

9:59 PM

@kan I'm asking why this shouldn't work on Debian. Can you try with "less /etc/profile.d/texlive.sh"?

Paulo Cereda

@kan egreg forced a PATH setup.

kan

export PATH=/opt/texbin:$PATH

There is just this line that gets displayed...

egreg

@kan Braces are missing! I don't know if this really makes a difference. It should be export PATH=/opt/texbin:${PATH}

kan

@egreg Oops!!! OK, I'll fix that...

Paulo Cereda

@egreg It should not make a difference, unless Debian proves me wrong. :)

David Carlisle

10:03 PM

@PauloCereda should only need the {} if needed to distinguish from following letters

Paulo Cereda

@DavidCarlisle Ah yes. :)

@kan: please, $ less /etc/profile.d/texlive.sh

kan

Oops! No Luck either after the {}

@PauloCereda Just a sec:

export PATH=/opt/texbin:${PATH}

David Carlisle

is @kan using bash... ? csh and vim users have different rules...

kan

@DavidCarlisle Yes, the shell is definitely bash.

egreg

@kan Try logoff and login

Paulo Cereda

10:07 PM

@DavidCarlisle :q

kan

@egreg Hmm, no luck yet... should I make it executable?

Paulo Cereda

@kan $ less /etc/profile.d/texlive.sh please.

kan

@PauloCereda export PATH=/opt/texbin:${PATH}

Paulo Cereda

@kan No shebang?

kan

@PauloCereda no...

do I add one

Paulo Cereda

10:11 PM

@kan Please do.

#!/bin/bash
export PATH=/opt/texbin:${PATH}

kan

Oh my dear!

No luck even after this! :(

David Carlisle

@kan so if you set the path by hand in a terminal ie just execute export PATH=/opt/texbin:${PATH} does tex then work as expected?

Paulo Cereda

@DavidCarlisle It did, egreg suggested it a few lines before.

kan

@DavidCarlisle yes! asking which tex after executing that line does tell me /opt/texbin/tex

egreg

@PauloCereda One can always put the change to PATH in .bashrc

David Carlisle

10:16 PM

@PauloCereda shebang cant help can it? the file has to be executed by the current shell anyway if it has to look uo a new shell via that teh variable will be set in a subshell

kan

So, is there a brute force way to do it?

Paulo Cereda

@DavidCarlisle Indeed, but it might be use for non-interactive sessions. :)

@kan Install Windows. :)

kan

@PauloCereda Oy! NO WAY! :)

egreg

@kan Add the line export PATH=/opt/texbin:${PATH} to your .bashrc file

kan

I had genuine windows and got rid of it for ubuntu...

Alan Munn

10:17 PM

@kan Get a Mac. :)

Paulo Cereda

@kan: my suggestion (and of course @egreg's): add it to .bash_profile.

kan

@AlanMunn I am a poor undergraduate student. But, I am now saving some money for this... :)

Alan Munn

@kan Sorry to be making fun in the middle of your frustrations. Blame @PauloCereda, he started it. :)

egreg

@PauloCereda I'll never learn the hierarchy. ;-)

David Carlisle

@kan do what I do, install windows then install cygwin, then pretend you are on linux anyway:-) (or simpler just add the line to .bashrc or .profile or .bash_profile

Paulo Cereda

10:19 PM

@AlanMunn Hey! :)

@egreg Neither do I. It gave me trouble when setting paths in my Mac. :)

WAIT A MINUTE!

@kan: Please, cat /etc/environment

kan

OK, there are several suggestions here! which one should I edit:

Paulo Cereda

Now I'm enraged.

kan

@PauloCereda I get back nothing... :(

Paulo Cereda

@kan hmmmmm

kan

the prompt is returned...

egreg

10:20 PM

@PauloCereda The file exists and is empty.

Paulo Cereda

@egreg We could try adding the export line in there.

egreg

@PauloCereda When I tried doing things with /etc/environment I ended up with a hanged system (but it wasn't Debian, IIRC).

Paulo Cereda

@egreg ooh sounds dangerous. :) Let's try it! :)

By the way, can we install cowsay in Mac via brew? :)

egreg

@PauloCereda Error: No such keg: /usr/local/Cellar/cowsay

Paulo Cereda

@egreg Oh no.

@egreg: you are right, I think the correct file is .bashrc.

egreg

10:27 PM

@PauloCereda It should be read in also by non interactive shells

Paulo Cereda

@kan: please, $ source /etc/profile.d/texlive.sh

then which tex

kan

@PauloCereda Works too!

Shows the /opt/texbin/tex

Paulo Cereda

@kan Reboot the machine.

:)

kan

Hmm!! OK!

Oh man! :(

I hate this!

No luck @PauloCereda :(

Paulo Cereda

@kan Oh sorry.

kan

10:31 PM

No problem...

We are trying to debug the issue I guess...

David Carlisle

/etc/profile.d/texlive.sh is (should be) setting the system default path but is your user profile using that or does it go PATH=/a/b/:c and over-ride it?

kan

@DavidCarlisle how do I test this?

Paulo Cereda

@DavidCarlisle Let's summon Norbert. :)

egreg

@kan Have you some export PATH... in the .bashrc file?

kan

@egreg @DavidCarlisle Here is what I asked and got:

$ less .bashrc | grep "export"
   export PATH=$PATH:/home/knsam/epd_free-7.3-2-rh5-x86_64/bin
   export PATH="/usr/local/heroku/bin:$PATH"

egreg

10:41 PM

@kan Try also in .profile and .bash_profile

David Carlisle

@kan they just add to the ends of the default path, so look OK, it can't hurt much to add your texpath to that second line /opt/texbin:/usr/local/heroku/bin:$PATH but better would be to work out why default setting didn't work

kan

@egreg One more candidate now:

export PATH=$PATH:/home/knsam/epd_free-7.3-2-rh5-x86_64/bin
export PATH="/usr/local/heroku/bin:$PATH"
export PATH="$HOME/.rbenv/bin:$PATH"

I asked:

less .bashrc .profile .bash_profile | grep "export"

today might be a peculiar day!!

egreg

@kan Again, these lines should only add to the PATH. But for the moment, adding /opt/texbin as suggested should keep you in line. The route via texlive.sh is for having the setting system wide.

kan

NOTHING works!!

emacs has path difficulties now... eeks.

egreg

@kan Welcome to the wonderful world of applied computer science. ;-)

Paulo Cereda

10:46 PM

@kan Yay! :)

@egreg Meanwhile, in the theoretical CS alley... :)

kan

@PauloCereda Actually, I checked the variable load-path and see that the path is in there but then, emacs complains on startup...

Paulo Cereda
