Top Forums Shell Programming and Scripting Replace values in script reading line by line using sed Post 302918873 by crimsonengineer on Friday 26th of September 2014 01:09:47 AM
Old 09-26-2014
So my output would be a script containing the values in the text file:

Quote:
for pa in 14.5
blah blah
do
for pb in 16.7
blah blah
do
I would like my script to repeat for each row in the text file. I think this can be accomplished with sed or awk, but unsure how to piece together the proper commands. Thanks so much.

NAME
Template::Test - Module for automating TT2 test scripts SYNOPSIS
use Template::Test; $Template::Test::DEBUG = 0; # set this true to see each test running $Template::Test::EXTRA = 2; # 2 extra tests follow test_expect()... # ok() can be called any number of times before test_expect ok( $true_or_false ) # test_expect() splits $input into individual tests, processes each # and compares generated output against expected output test_expect($input, $template, \%replace ); # $input is text or filehandle (e.g. DATA section after __END__) test_expect( $text ); test_expect( *DATA ); # $template is a Template object or configuration hash my $template_cfg = { ... }; test_expect( $input, $template_cfg ); my $template_obj = Template->new($template_cfg); test_expect( $input, $template_obj ); # $replace is a hash reference of template variables my $replace = { a => 'alpha', b => 'bravo' }; test_expect( $input, $template, $replace ); # ok() called after test_expect should be declared in $EXTRA (2) ok( $true_or_false ) ok( $true_or_false ) DESCRIPTION
The "Template::Test" module defines the test_expect() and other related subroutines which can be used to automate test scripts for the Template Toolkit. See the numerous tests in the t sub-directory of the distribution for examples of use. PACKAGE SUBROUTINES
text_expect() The "test_expect()" subroutine splits an input document into a number of separate tests, processes each one using the Template Toolkit and then compares the generated output against an expected output, also specified in the input document. It generates the familiar "ok"/"not ok" output compatible with "Test::Harness". The test input should be specified as a text string or a reference to a filehandle (e.g. "GLOB" or "IO::Handle") from which it can be read. In particular, this allows the test input to be placed after the "__END__" marker and read via the "DATA" filehandle. use Template::Test; test_expect(*DATA); __END__ # this is the first test (this is a comment) -- test -- blah blah blah [% foo %] -- expect -- blah blah blah value_of_foo # here's the second test (no surprise, so is this) -- test -- more blah blah [% bar %] -- expect -- more blah blah value_of_bar Blank lines between test sections are generally ignored. Any line starting with "#" is treated as a comment and is ignored. The second and third parameters to "test_expect()" are optional. The second may be either a reference to a Template object which should be used to process the template fragments, or a reference to a hash array containing configuration values which should be used to instantiate a new Template object. # pass reference to config hash my $config = { INCLUDE_PATH => '/here/there:/every/where', POST_CHOMP => 1, }; test_expect(*DATA, $config); # or create Template object explicitly my $template = Template->new($config); test_expect(*DATA, $template); The third parameter may be used to reference a hash array of template variable which should be defined when processing the tests. This is passed to the Template process() method. my $replace = { a => 'alpha', b => 'bravo', }; test_expect(*DATA, $config, $replace); The second parameter may be left undefined to specify a default Template configuration. test_expect(*DATA, undef, $replace); For testing the output of different Template configurations, a reference to a list of named Template objects also may be passed as the second parameter. my $tt1 = Template->new({ ... }); my $tt2 = Template->new({ ... }); my @tts = [ one => $tt1, two => $tt1 ]; The first object in the list is used by default. Other objects may be switched in with a '"-- use $name --"' marker. This should immediately follow a '"-- test --"' line. That object will then be used for the rest of the test, or until a different object is selected. -- test -- -- use one -- [% blah %] -- expect -- blah, blah -- test -- still using one... -- expect -- ... -- test -- -- use two -- [% blah %] -- expect -- blah, blah, more blah The "test_expect()" sub counts the number of tests, and then calls ntests() to generate the familiar ""1..$ntests "" test harness line. Each test defined generates two test numbers. The first indicates that the input was processed without error, and the second that the output matches that expected. Additional test may be run before "test_expect()" by calling ok(). These test results are cached until ntests() is called and the final number of tests can be calculated. Then, the ""1..$ntests"" line is output, along with ""ok $n"" / ""not ok $n"" lines for each of the cached test result. Subsequent calls to ok() then generate an output line immediately. my $something = SomeObject->new(); ok( $something ); my $other = AnotherThing->new(); ok( $other ); test_expect(*DATA); If any tests are to follow after "test_expect()" is called then these should be pre-declared by setting the $EXTRA package variable. This value (default: 0) is added to the grand total calculated by ntests(). The results of the additional tests are also registered by calling ok(). $Template::Test::EXTRA = 2; # can call ok() any number of times before test_expect() ok( $did_that_work ); ok( $make_sure ); ok( $dead_certain ); # <some> number of tests... test_expect(*DATA, $config, $replace); # here's those $EXTRA tests ok( defined $some_result && ref $some_result eq 'ARRAY' ); ok( $some_result->[0] eq 'some expected value' ); If you don't want to call "test_expect()" at all then you can call "ntests($n)" to declare the number of tests and generate the test header line. After that, simply call ok() for each test passing a true or false values to indicate that the test passed or failed. ntests(2); ok(1); ok(0); If you're really lazy, you can just call ok() and not bother declaring the number of tests at all. All tests results will be cached until the end of the script and then printed in one go before the program exits. ok( $x ); ok( $y ); You can identify only a specific part of the input file for testing using the '"-- start --"' and '"-- stop --"' markers. Anything before the first '"-- start --"' is ignored, along with anything after the next '"-- stop --"' marker. -- test -- this is test 1 (not performed) -- expect -- this is test 1 (not performed) -- start -- -- test -- this is test 2 -- expect -- this is test 2 -- stop -- ... ntests() Subroutine used to specify how many tests you're expecting to run. ok($test) Generates an ""ok $n"" or ""not ok $n"" message if $test is true or false. not_ok($test) The logical inverse of ok(). Prints an ""ok $n"" message is $test is false and vice-versa. callsign() For historical reasons and general utility, the module also defines a "callsign()" subroutine which returns a hash mapping the letters "a" to "z" to their phonetic alphabet equivalent (e.g. radio callsigns). This is used by many of the test scripts as a known source of variable values. test_expect(*DATA, $config, callsign()); banner() This subroutine prints a simple banner including any text passed as parameters. The $DEBUG variable must be set for it to generate any output. banner('Testing something-or-other'); example output: #------------------------------------------------------------ # Testing something-or-other (27 tests completed) #------------------------------------------------------------ PACKAGE VARIABLES
$DEBUG The $DEBUG package variable can be set to enable debugging mode. $PRESERVE The $PRESERVE package variable can be set to stop the test_expect() from converting newlines in the output and expected output into the literal strings ' '. HISTORY
This module started its butt-ugly life as the "t/texpect.pl" script. It was cleaned up to became the "Template::Test" module some time around version 0.29. It underwent further cosmetic surgery for version 2.00 but still retains some remarkable rear-end resemblances. Since then the "Test::More" and related modules have appeared on CPAN making this module mostly, but not entirely, redundant. BUGS
/ KNOWN "FEATURES" Imports all methods by default. This is generally a Bad Thing, but this module is only used in test scripts (i.e. at build time) so a) we don't really care and b) it saves typing. The line splitter may be a bit dumb, especially if it sees lines like "-- this --" that aren't supposed to be special markers. So don't do that. AUTHOR
