NYTPROFCSV(1)

💖 NYTPROFCSV — the nytprofcsv manual page, bestie edition 💖

okay so this is the manual page for nytprofcsv, from the User Contributed Perl Documentation section (that's section 1, aka "you type this in a terminal"). sit down, grab a strawberry, we're doing CSV profiling reports 🍓✨

✨ NAME ✨

nytprofcsv — (DEPRECATED) the CSV format implementation of Devel::NYTProf::Reader

say it with me: DEPRECATED. it's giving "still works but its days are numbered" 💀

---

🦋 SYNOPSIS 🦋

 $ nytprofcsv [-h] [-d] [-o <output directory>] [-f <input file>]

 perl -d:NYTProf some_perl_app.pl
 nytprofcsv
 Generating CSV Output...

like. you profile your app, you run nytprofcsv, and boom — CSV. that's the whole arc 💅

---

🎀 NOTE 🎀

nytprofcsv is deprecated and will be removed in a future release.

no cap, this is a warning: it will be removed. future release. gone. don't build your whole pipeline on it unless you love chaos 🙈

---

💜 DESCRIPTION 💜

nytprofcsv is a script that implements Devel::NYTProf::Reader to create comma-separated value formatted reports from Devel::NYTProf databases.

for more info, go look at the Devel::NYTProf Perl code profiler. it's the main character of this whole story 👑

🌈 COMMAND-LINE OPTIONS 🌈

these are the command line options understood by nytprofcsv, and yes bestie, we're listing all of them 💖

• -f, --file <filename> — tells it where the input file lives. heads up: the input file must be the output of fprofpp. default: nytprof.out
• -o, --out <dir> — where the generated report gets dropped. default: ./nytprof/
• -d, --delete — purges any existing database located at whatever -o (above) is set to. like, it deletes it. at that path. that's the vibe 🗑️
• -h, --help — prints the help message. the classic ✨

---

🌸 SAMPLE OUTPUT 🌸

here's what it spits out, and honestly? look at those numbers being all tidy and comma-separated 🥹

 # Profile data generated by Devel::NYTProf::Reader v.0.01
 # Format: time,calls,time/call,code
 0,0,0,#--------------------------------------------------------------------
 0,0,0,# My New Source File!
 0,0,0,#--------------------------------------------------------------------

 0,0,0,package NYT::Feeds::Util;
 0.00047,3,0.000156666666666667,use Date::Calc qw(Add_Delta_DHMS);
 0.00360,3,0.0012,use HTML::Entities;
 0.00212,3,0.000706666666666667,use Encode;

 0.00468,3,0.00156,use strict;
 0,0,0,
 0.00000,1,0,require Exporter;
 ... that's enough, get the picture? ...

Note: that format line tells you which fields the numbers correspond to. it's the key, iykyk 🔑

Note2: if the source file gets modified between profiling and report generation, the source might be misaligned. so like, don't touch the file mid-process, bestie 😭
