Meditations

( #480=superdoc: print w/replies, xml ) Need Help??

If you've discovered something amazing about Perl that you just need to share with everyone, this is the right place.

This section is also used for non-question discussions about Perl, and for any discussions that are not specifically programming related. For example, if you want to share or discuss opinions on hacker culture, the job market, or Perl 6 development, this is the place. (Note, however, that discussions about the PerlMonks web site belong in PerlMonks Discussion.)

Meditations is sometimes used as a sounding-board — a place to post initial drafts of perl tutorials, code modules, book reviews, articles, quizzes, etc. — so that the author can benefit from the collective insight of the monks before publishing the finished item to its proper place (be it Tutorials, Cool Uses for Perl, Reviews, or whatever). If you do this, it is generally considered appropriate to prefix your node title with "RFC:" (for "request for comments").

#p5p finds your lack of failing tests disturbing

    5.26 will come with a major change in how Perl builds and runs modules. The current directory will not be in @INC when running Perl programs.

    This affects all programs that call require or use and expect files relative to the current directory to be available. Besides plugin systems, any Makefile.PL using for example Module::Install is a likely offender. So far very little has been caught in the net of CPAN testers.

    As an example, one of my tests loads Makefile.PL:

    use lib '.'; use vars '%module'; require 'Makefile.PL'; # Loaded from Makefile.PL %module = get_module_info(); my $module = $module{NAME};

    This will fail under 5.26+ without the use lib '.'; statement at the top.

    I've altered @INC, pray I do not alter it further

    If you want to check whether your modules should still work and test OK under the upcoming 5.26 release, I think that the following oneliner should give you a good indication:

    perl -M-lib=. Makefile.PL && make && make test

    If you run author tests or prefer your tests to be run using prove, you have to take care of prove invoking a fresh Perl:

    # Windows syntax: set PERL5OPT=-M-lib=. perl Makefile.PL && dmake && prove -bl xt t
    @rem Shell syntax: export PERL5OPT=-M-lib=. perl Makefile.PL && make && prove -bl xt t

    Please test your distributions and release new versions if they need . in @INC. Thanks!

    Update: Added call to action and noted where use lib '.' helps.

    As i'm aged 60 + i guess i'll never get a new job. I think i need to face retirement. I first thought to delete my account on PM and through away all the code i ever wrote as well as my hand library and forget about everything related to programming. But it isn't so easy. I spent the last 20 years with this stuff. I'll stay a bit here - for fun. And perhaps i'll learn a new programming language ;-)

    Update: What should i say? I'm deeply moved. Thank you very much to all for encouragement and good advice.

    Best regards, Karl

    Trolling is very powerful. It does not fool many here, but it CAN fool the unwary. Information is becoming consumed as such a fast pace that it becomes scary. Ideas are very powerful, but elders and young people must learn to build their character, use logic to question their own bias, work very hard to embrace change peacefully. Violence scares me because I'm a veteran and have seen what it can do. I will not take for granted that it can not happen here, but I will also not let fear rule my life. When it is used, must be used morally for self defense only. Many may question if to use this tool for selfish purposes during the coming years. The answer is no.

    I can not know if our leaders are moral, but people lose faith in their credibility anyways because they can not question them for themselves. Social contract is very important idea, but the future is here and social contracts are made with web sites, gives people a sense of belonging, and COMMUNITY is very important concept. But one must choose to belong in online communities that promote moral behavior.

    Question the rules, especially demagougery, embrace change peacefully. I think how stupid this game is, agree that it is just a list on the internet, but what if the desire to become on this list could show one 5 year old terrorists mind to learn perl instead of bomb making? Or show someone who was just fired; do this in the mean time and not worry too much. Your quality of life may suffer, but you can still belong to a community that values you. What certainly is true is that information can trigger a fight or flight mechanism in people. This scared me but, easily harnessed, just go exercise. Learn value of this game in US Military Monastery.

    A troll is someone who spreads fear, has no character to resist impulses, does not vote on evaluation of content, uses bias to marginalize others ideas instead of defeating them through reflection using logic, not ignore, this is bad way to defeat. There are many demagogues in the world that teach stupid ideas, people embrace them because they are scared, have little hope.

    I have studied in this school for 5 years, and it is my favorite online community! I would keep it sharp, use my talents to make it grow, make sure value is recognized. I think this xp game will be taken more seriously by millennials than you think. I also think pm will survive many efforts at marginalization, and I think perl will too. Because it is a great tool and there are years of evidence in the Monastery so people can judge for themselves. It is not which tool that is important as long as the tool you pick up is not used for violence|hacking.

    Quick opinion-related question on a slow, test-writing Sunday afternoon.

    Has anyone dabbled with the new Test2 framework at all? Are you using it in your CPAN and/or production projects?

    If so, what are your thoughts about it, and what are the pros/cons you've found so far?

Ayn Rand vs. Stewart Brand

    Let the flame wars begin! Everything is political, even programming languages. So why not discuss it?

    I came of computing age in the early 90s in the Bay Area when the WELL was still a big thing (granted I never got on the [I|i]nternet proper until '95 and stuck only to BBS networks). Back then there was still a strong whiff of hippie counter-culture around. Though I never met the man and know next to nothing about him personally, it's fairly obvious that Larry Wall is a product of that culture and the guiding light behind Perl culture in general. I could be wrong (and I'm not well versed on this topic so I may very well be), but my impression is that his guiding philosophy is part of the same mindset spawned by Stewart Brand and the WELL network Brand helped to found.

    As younger coders come along, I get the strong sense there is a distinct shift away from these roots and toward a more Ayn Randian philosophy, largely adopted by younger Silicon Valley venture capitalists which appears to be trickling down to its workforce. This adoption of Randian politics has been noted in the press such as this article.

    This post is not meant to be a criticism of this change, but more of an observation (with a disclaimer that being a very early 70s born gen-xer, I definitely have more sympathies with the hippie culture). Being a lone wolf, I don't come into any contact at all with other programmers so I don't get to see any of this firsthand. So I'm wondering how others more steeped in Perl culture worry–or not worry–about this change and I also wonder just how large of a change there is, especially within the Perl community. How much do you think Perl's success is owed its founding culture and what happens to Perl as the older programmers fade away? Does Perl stand a chance in a culture where only alpha dogs matter?

Yet Another Appeal for Civility

    Can't we all just get along?

    Apparently not, but can't we at least all make a more concerted effort? I've always seen the monastery as pretty good at this, especially relatively speaking in regard to the internet in general, but that doesn't mean it can't be better. Note my intention isn't to call out any specific monk here, the linked example is just that, an example of what I mean. Tone matters... a lot. Comments shouldn't be discouraged, that's not what I'm saying, but a comment with the exact same message and a different tone can be changed from a perceived personal attack to a helpful suggestion. That's inherently more productive. My favorite node put it far more clearly, succinctly, elegantly, and humorously than I ever could.

    I'm quick to make a joke, probably because I'm one of those psychologically damaged people who uses humor as a defense mechanism and attempted means of validation to the group... guilty. :-) But even when I'm inclined to do so, I always try to stop and ask myself if I'm just going to end up being this guy. You'll all have to take my word for it when I say I decide not to post a potentially offending quip far more often than I decide to post one. That's especially true if I feel someone is going to take it as a personal attack, though I admit I'm far from perfect in my execution. Oh great Saint Erudil give me strength and guidance.

    This is just food for thought, and yet another such post for appeal to civility to be read and quickly forgotten. Remember, "What should it profit a man, if he should win a flame war, yet lose his cool?" :-)

    UPDATE: TL;DR - An overly idealistic perldigious sings for peace in to the microphone. Some more experienced and realistic Monks quietly pull him aside and remind him that you can't expect all people to play nice. Oh, and please forgive me if I insist on futilely preaching to mental patients, criminals, terrorists, or even just the wind every now and then if it makes me feel better. :-)

    Just another Perl hooker - And definitely not the kind with any $class whatsoever.

    For some reason a few people here think that you need more than
    !prove -lr
    
    This is all you need to run your test suite from vim.

    The -l option is used to include your lib/

    The -r option is used to find all tests in any children directories inside t/.

    It really is just that simple. Furthermore, this is Universal, unlike using a wrapper and mapping actions to some vim command.

A recipe for testing and debugging with vim

    I've patched together some vim scripts, a vim plugin, tmux, perl modules, and a three-line bash script to create an efficient way of running and debugging my code with minimal effort. I thought I'd share and get some feedback and maybe others will find this useful, too. As easy as this is to get set up, it took me a lot of trial and error to get right so hopefully I will save some of you out there looking to do something similar a lot of pain and aggravation. And, yes, I realize there are other vim plugins for this task but none of them satisfied my exact needs (especially the syntax highlighting) or they came with lots of other baggage I didn't want or need. Plus, I wanted to get more familiar with vim so I decided to roll my own.

    Note: I don't believe this will work with gvim because this solution relies on tmux, a terminal-based program.

    Synopsis

    With a *.t test file open in vim, hit <F7> (without even having to save first!) to run a prove command on your test. The output of the test gets opened in a new tmux pane (Pane B) to the right of my vim window. As the test runs, you can still edit your file since output of the test is in a tmux pane. The other advantage to seeing the live output of prove is that it gives your peace of mind that your script is actually working while also getting a rough gauge on which parts of the code are slow or if your script is stuck in some infinite loop. Mixed in with prove's output are messages generated by the Log4perl module (trace, debug, info, etc. statements). Once the script finishes running, prove's raw output in Pane B gets replaced with a new vim session which pulls in prove's output that was saved using prove's --archive option. The reason for re-displaying prove's output in vim is so you can have it syntax highlighted to a high degree to help you pick out the relevant files and line numbers where errors occurred, as well as easily pick out debug information and other useful output. After the test script's output gets loaded into vim, focus is automatically returned back to your test file in the pane on the left. Once errors and warnings are fixed up, you can code some more and then hit <F7> again to start the process over.

    Ingredients needed

    • vim text editor
    • tmux terminal multiplexer
    • log4perl module (optional)
    • Test::More module plus other test modules you may desire
    • A simple bash script
    • simple vim scripts that go into the .vimrc file
    • tmuxify vim plugin
    • vim file for syntax highlighting of test output
    • A wide monitor to accommodate a wide terminal window (optional)

    I won't go into any detail on getting any of these components installed or how they work. Google is your friend.

    vim config

    Here are the needed lines to get your vim files working with the tmuxify plugin once it's installed. Replace <your_home_directory> in the last line with something suitable for your machine. If you don't have a wide terminal, or want your output to appear along the bottom of the your test script instead of next to it, change the -h in the third line to a -d.

    nmap <F7> :w<CR>\mk:q!\ms<CR>\mq\mr imap <F7> <ESC>:w<CR>\mk:q!\ms<CR>\mq\mr let g:tmuxify_custom_command = 'tmux split-window -h' let g:rel_file_name = @% let g:tmuxify_run = { 'perl': '<your_home_directory>/run_tests.sh ' . +g:rel_file_name }

    vim syntax highlighting file

    This is what makes the output of your test code super readable. In your .vim directory, create a new directory called syntax (if it doesn't already exist) and place the following code into a file called test.vim. You can, of course, tweak and improve this to your liking. I am not an expert at vim syntax highlighting so this can probably be improved and definitely shortened a great deal.

    syn match Good "^ok " syn region okline contains=Good start="^ok" end="\n" syn match builder_line "Builder\.pm line \d\+\." syn match lineno "line \d\+\.*\n" syn match line_no "Line \d\+\:" syn match error_msg "^# \t.*at"hs=s+3 syn match perl_lib "perl_lib\/.*\.pm"hs=s+9 syn match file " at [^\/]\+\.p[ml] "hs=s+3 syn match subtest_file "^\s\+#\s\+.*at .*line \d\+\.\n"hs=s+5 syn match test_file "\/[^\/]\+\/t\/.*\.t "hs=s+1 syn match my_error "^[^(ok |not ok |#)].*line \d\+\.\n" syn region not_ok_subtest contains=subtest_file start="^\s\+not ok \d\ ++" end="^\s\+#.*expected.*\n" " end="^\s\+#.*line \d\+\.\n" syn region Bad contains=warning start="^not ok " end="^\ze[^#]"re=e-1, +he=e-1 syn region warning contains=test_file,file,lineno,perl_lib,error_msg,b +uilder_line start="^#\s\+Failed" end="^\ze[^#]"re=e-1,he=e-1 syn match comment "^#.*\n" syn match premature "^# Looks like.*\n" syn region dump start="$VAR\d\+\s=\s"rs=s-1 end=";\n" syn match divider "----*" syn match warn 'WARN\|ERROR' syn match script contains=warn '[A-Z]\{4,5}.*> ' hi Good cterm=bold ctermfg=Green hi divider cterm=bold ctermfg=yellow ctermbg=black hi dump ctermfg=LightBlue hi okline ctermfg=Green hi warning cterm=none ctermfg=Red hi my_error cterm=none ctermfg=Red hi premature cterm=none ctermfg=Red hi failed cterm=none ctermfg=Red hi Bad cterm=bold,underline ctermfg=Red&#9251; hi comment ctermfg=Cyan hi lineno ctermfg=White hi line_no ctermfg=White hi file ctermfg=White hi test_file ctermfg=White hi perl_lib ctermfg=White hi error_msg ctermfg=Green hi builder_line cterm=none ctermfg=Red hi not_ok_subtest ctermfg=Red hi warn ctermfg=Red hi subtest_file ctermfg=White hi script ctermfg=White

    Bash script

    This simple script gets run by tmuxify when you hit the <F7> key. Call the file run_tests.sh and place it into the home directory on your machine (the same directory referenced in the .vimrc file above.

    prove --merge --normalize -v $1 -a test.tgz vim -nR -c ":silent 0read ! tar xfO test.tgz $1" -c ':set nonumber' -c + ':syntax sync fromstart' -c ':set syntax=test' -c ':silent !tmux se +lect-pane -L' !!! PUT A BLANK LINE HERE !!!!

    Note that the 3rd line should be a blank line. For some reason, it seems to be needed to avoid having to hit the return key after the last command is run. And don't forget to chmod the bash file to make it executable.

    Other good stuff

    You will of course need to make sure your test file has use Test::More at the top of the file. Also, I highly recommend the log4perl module to help sprinkle your output with helpful debug output and other useful information that will help you keep track of what your code is doing and how it is behaving.

    That's it. Happy testing and debugging!

RFC: My first GitHub contribution

    Hi there everyone, I made my first contribution to an open source project today. Well, to be honest, the project was just a list of links and the contribution was just a script that most of you could have hacked together in 10 minutes... But I felt really good about it :D.

    Why did I make this script?

    I am a frequent visitor of the programmer discord server, which is a discord server for programmers (surprise, surprise). This server was started by a couple of programming enthusiasts over at reddit. It has grown out to a huge community of 5000+ programmers, with at least 1000 programmers concurrently online at any time of the day to discuss programming with and to get real time support from when you get stuck. One of the channels on this server is titled Collaborations-and-projects, and someone posted there that he had made a list of resources for people who want to learn about programming/computer science. The only problem was that now that he had made this list, it was going to be a huge pain to sort all of the resources by name in alphabetic order per category. To which my response was, of course, "THIS IS A TASK FOR PERL". So I asked for the link to his GitHub repo, put this script together, and let it run through all of the files in the repo, after which I committed all the changes.

    links I would like to share

    • The link to join the programmer discord: https://discord.gg/9zT7NHP At the moment there is no Perl channel there yet, and when I asked why, they told me there was no interest!! So please, if you feel like it, join the server so that there is yet another place to discuss Perl in this world :)
    • The link to the GitHub repository I contributed to: https://github.com/TumblrCommunity/coding-masterpost

    Now, as I am pretty new to Perl (and just started programming this year) and I'm sure that my code is pretty clunky because of that, I figured that it might be a good idea to ask for some comments on the first 30+ line program I have ever written in Perl. Are my comments on point for example? Should I comment more/less? And could my code have been shorter? Please feel free to criticize every single character and white space in my script! It won't hurt me (much).

    First I'll give you an idea of the way the files are formatted; The <> tags are not in the real files!

    # <CATEGORY HEADER> [<name of resource>] (www.hyperlink.com) some text about the resource [<name of resource>] (www.hyperlink.com) some text about the resource [<name of resource>] (www.hyperlink.com) some text about the resource #<HEADER OF NEXT CATEGORY> [<name of resource>] (www.hyperlink.com) some text about the resource [<name of resource>] (www.hyperlink.com) some text about the resource

    Now my $code:

Resolving issues while installing Net::SSH2 on Ubuntu 16.04.2

    Hi,

    I wanted to try out plenv and install modules without "disturbing" system perl. Followed the instructions and plenv installed without any issues. While installing the Net::SSH2 modules, I kept getting errors. The steps given below are for those who might face similar issues. Hope someone here finds it helpful.

    Apologies if this is posted in wrong section. Just wanted to post this to help those who might be in a similar situation

    Before you install Net::SSH2, install the following:

    sudo apt install libssh2-1-dev sudo apt install openssh-server sudo apt install zlib1g-dev

    Once these are installed successfully, then proceed with installing the Net::SSH2 module. Since I had earlier installed plenv, it seems to have installed cpanm in my home directory as shown below.

    pritesh@thinkpad:~$ which cpanm /home/pritesh/.plenv/shims/cpanm pritesh@thinkpad:~$

    Then I simply installed Net::SSH2 using the following command

    cpanm Net::SSH2

    Then just to see if all is well, I ran the following command

    pritesh@thinkpad:~$ perl -e "Net::SSH2" pritesh@thinkpad:~$

    Updated as per the error pointed out. Thanks.

    pritesh@thinkpad:~$ perl -e "use Net::SSH2" pritesh@thinkpad:~$

    Indeed all is well.

    Note:- Big thank you to the Strawberry Perl folks. While on Windows, I was using Strawberry Perl and installing a module was trivial. Only upon trying to install the Net::SSH2 module on linux did I understand how much care the Strawberry Perl folks have taken to make things work on Windows.

    Unfortunately I will not be able to go back to Windows on this laptop. After upgrading the RAM, Windows would not boot. Reinstalling the OS also did not help and I kept getting random blue screens, both with Windows 7 and 10. Memory tests ran all fine. So tried Ubuntu 16.04.2 and it seems to have no issues.

    As a hobbyist programmer and someone fascinated with the world of programming and learning what I can about it, it strikes me more and more just how obsessive to detail good programmers are. That's never been a strong suit of mine, unfortunately. I'm impatient and I often make wrong and bad assumptions that make it tough for me to write solid code. And I think what I like about programming so much–even though it often humbles me by making me feel like a bit of a dunce–is that it forces me to think like an engineer. But I have to work pretty damn hard at it and the process is slow and frequently frustrating.

    In the programming field, there is an extraordinary amount of information to take in, process, and put into practice. It seems the more I learn, the less I feel like I know. I marvel at the programmers to be able to do that and who have a natural knack for it. I'd like nothing better than to spend 15 hours a day lost in code (which I've been doing lately) but it still sometimes feels like I'm pushing a rock up a mountain. I have a few projects I want to write and write well but I end up getting diverted by having to learn some new skill first. Every day there seems to be countless new idioms, tools, and concepts that I need to learn and put into practice.

    But I'm eager for the day when it all just clicks, when I can look at someone else's piece of code and read it like a newspaper and know everything that's going on with it (or at least have a pretty good idea). It's frustrating to go down three dead ends or spend an hour figuring out why your code won't do what you want because of a stupid mental error. I'm guessing most programmers like me have gone through a similar phase where they can write code that gets simple stuff accomplished but aren't good enough to take on a really large or complex project.

    Anyway, just needed to vent. I feel better now. And thanks to the Perlmonks who have helped me on my journey toward my goal of achieving programming excellence. I could not keep pushing on this rock without you.

Working Solo and in a Team

    I've worked solo, and in teams, for many years now, and in many different organisations. Yet I still feel dissatisified somehow.

    While I enjoy working alone -- especially when I'm in the zone -- I have to acknowledge that individuals working alone in my organisations have produced some pretty quirky and unmaintainable code over the years. At least, that's what I've seen.

    Moreover, I write better and more relevant code not when working solo, but when receiving regular feedback from others.

    Sadly, I've found that working closely with others can be difficult and stressful, especially when personality clashes arise. The tragic human condition -- as I'm reminded every day when reading the news -- is that there are so many factors that can cause conflict in teams: gender, politics, religion, baby boomers vs generation-y, introvert versus extrovert, perl vs java, the list goes on and on.

    Pair Programming

    One of the drawbacks of being chosen to lead humanity's push to become an interplanetary species is having to give up your privacy. "You could hear everything else that happened in the dome, and they could hear you," Ms Johnston recounted.

    I've tried pair programming eight hours a day and hated it. Like the budding Mars astronauts, I discovered how much I value my privacy.

    High Performing Teams

    Despite my unfortunate pair programming experiences, I acknowledge the crucial importance of teamwork and effective teams. Though I've rarely experienced it personally, I know that the elusive harmonious, high performing team is certainly possible. How best to achieve it?

    According to a recent study at Google the five keys to a successful team are:

    • Psychological safety: Can we take risks on this team without feeling insecure or embarrassed?
    • Dependability: Can we count on each other to do high quality work on time?
    • Structure & clarity: Are goals, roles, and execution plans on our team clear? Do we have an effective decision-making process?
    • Meaning of work: Are we working on something that is personally important for each of us?
    • Impact of work: Do we fundamentally believe that the work we're doing matters?

    Some ideas you might try from the Google study to improve teamwork:

    • Google's gTeams exercise: a 10-minute pulse-check on the five dynamics above, a report that summarizes how the team is doing, a live in-person conversation to discuss the results, and tailored developmental resources to help teams improve.
    • Google found that teams who adopted a "new group norm" improved more than other teams. An example of a new group norm is "Kick off every team meeting by sharing a risk you took in the previous week".

    Feedback

    I'd love to hear of your experiences. What's been your workplace experiences, both working solo, and in a team? Which do you prefer? I'm especially interested to learn what you feel is the key to working in an effective team.
