Hello!
I am writing a program to run through two large lists of data (~300,000 rows), find where rows in one file match another, and combine them based on matching fields. Due to the large file sizes, I'm guessing AWK will be the most efficient way to do this. Overall, the input and output I'm... (5 Replies)

grep -v will exclude matching lines, but I want something that will print all lines but exclude a matching field. The pattern that I want excluded is '/mnt/svn'

Hi,
Please excuse for often requesting queries and making R&D, I am trying to work out a possibility where i have two files field separated by pipe and another file containing only one field where there is no matching columns, Could you please advise how to merge two files.

In the below I am trying to use awk to match all the $13 values in input, which is tab-delimited,
that are in $1 of gene which is just a single column of text.
However only the line with the greatest $9 value in input needs to be printed.
So in the example below all the MECP2 and LTBP1... (0 Replies)
Hi,
I have 2 tab-delimited input files as follows.
file1.tab:
green A apple

Return $1 of file1 if,
. $1 of file2 matches $3 of file1 and,
. any single element (separated by ";") in $3 of file2 is present in $2 of file1
In order to... (3 Replies)
Trying to use awk to match the contents of each line in file1 with $5 in file2. Both files are tab-delimited and there may be a space or special character in the name being matched in file2, for example in file1 the name is BRCA1 but in file2 the name is BRCA 1 or in file1 name is BCR but in file2...

In two previous posts (here) and (here), I received help from forum members comparing multiple fields across two files and selectively printing portions of each as output based upon would-be matches using awk.

Long time listener first time poster. Hope someone can advise.
I have two files, 1000+ lines in each, two fields in each file.
After performing a sort, what is the best way to find exact matches where field $1 and $2 in file1 are also present in file2 on the same line, then output only those... (6 Replies)

cgi::formbuilder::source::yaml
CGI::FormBuilder::Source::YAML(3pm) User Contributed Perl Documentation CGI::FormBuilder::Source::YAML(3pm)NAME
CGI::FormBuilder::Source::YAML - Initialize FormBuilder from YAML file
SYNOPSIS
use CGI::FormBuilder;
my $form = CGI::FormBuilder->new(
source => {
source => 'form.fb',
type => 'YAML',
},
);
my $lname = $form->field('lname'); # like normal
DESCRIPTION
This reads a YAML (YAML::Syck) file that contains FormBuilder config options and returns a hash to be fed to CGI::FormBuilder->new().
Instead of the syntax read by CGI::FormBuilder::Source::File, it uses YAML syntax as read by YAML::Syck. That means you fully specify the
entire data structure.
LoadCode is enabled, so you can use YAML syntax for defining subroutines. This is convenient if you have a function that generates valida-
tion subrefs, for example, I have one that can check profanity using Regexp::Common.
validate:
myfield:
javascript: /^[sS]{2,50}$/
perl: !!perl/code: >-
{ My::Funk::fb_perl_validate({
min => 2,
max => 50,
profanity => 'check'
})->(shift);
}
POST PROCESSING
There are two exceptions to "pure YAML syntax" where this module does some post-processing of the result.
REFERENCES (ala CGI::FormBuilder::Source::File)
You can specify references as string values that start with &, $, @, or \% in the same way you can with CGI::FormBuilder::Source::File.
If you have a full direct package reference, it will look there, otherwise it will traverse up the caller stack and take the first it
finds.
For example, say your code serves multiple sites, and a menu gets different options depending on the server name requested:
# in My::Funk:
our $food_options = {
www.meats.com => [qw( beef chicken horta fish )],
www.veggies.com => [qw( carrot apple quorn radish )],
};
# in source file:
options: @{ $My::Funk::food_options->{ $ENV{SERVER_NAME} } }
EVAL STRINGS
You can specify an eval statement. You could achieve the same example a different way:
options: eval { $My::Funk::food_options->{ $ENV{SERVER_NAME} }; }
The cost either way is about the same -- the string is eval'd.
EXAMPLE
method: GET
header: 0
title: test
name: test
action: /test
submit: test it
linebreaks: 1
required:
- test1
- test2
fields:
- test1
- test2
- test3
- test4
fieldopts:
test1:
type: text
size: 10
maxlength: 32
test2:
type: text
size: 10
maxlength: 32
test3:
type: radio
options:
-
- 1
- Yes
-
- 0
- No
test4:
options: @test4opts
sort: &Someother::Package::sortopts
validate:
test1: /^w{3,10}$/
test2:
javascript: EMAIL
perl: eq 'test@test.foo'
test3:
- 0
- 1
test4: @test4opts
You get the idea. A bit more whitespace, but it works in a standardized way.
METHODS
new()
Normally not used directly; it is called from CGI::FormBuilder. Creates the "CGI::FormBuilder::Source::YAML" object. Arguments from the
'source' hash passed to CGI::FormBuilder->new() will become defaults, unless specified in the file.
parse($source)
Normally not used directly; it is called from CGI::FormBuilder. Parses the specified source file. No fancy params -- just a single file-
name is accepted. If the file isn't acceptable to YAML::Syck, I suppose it will die.
