Help me please: UNIX command to extract substring not squeeze spaces
Hi experts,
Please help me!...
I have a string " test1 test2 test3 ".
There are two spaces before "test1"; There are four spaces between "test1" and "test2"; there are two spaces between "test2 and "test3".
I want to extract a substring "2 test3" using positions.
Below is my test script:
The result is "t3". It seems the multiple spaces are squeezed into one space between words.
How can I get "2 test3"?
Thank you so much in advance,
Sophie

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.
