I made a program that extracts quotes while retaining special inner quotes (in this case an 'x' followed by an apostrophe). The original program is far more complicated than this, but I wanted to make it simple to troubleshoot.
I want to take these two perl commands and have the first command's results be piped into the second commands input but while only running perl once:
Input: ['Say, x'Hix'']
Output: Say, x'Hix'
Taking the output of the first command:
Result (proper): Say, 'Hi'
I realise that I could easily just run perl twice and pipe them into eachother, but running perl twice seems inefficient; especially given that this command is ran thousands of times:
I've tried combining both commands in the code below, but it doesn't seem to be taking the output of the first command as input for the second:
Result (not what I want):
What is the correct format for a single command that would combine portions of 2 different lines in the command history? I'm using a C shell. Here's a simplified command history to clarify:
4 rm file1
5 ls -ld file2 file3 file4
6 cat file 5
With the above history, what would be the... (5 Replies)

Hello all,
I am trying to list and count all the files of a particular type in any given directory. I can use the commands separately but when I combine them they do not give an output.
The command for counting the files is ls -1 | wc -l and for listing all the file of particular type say... (2 Replies)

LaTeX::Encode(3pm) User Contributed Perl Documentation LaTeX::Encode(3pm)NAME
LaTeX::Encode - encode characters for LaTeX formatting
SYNOPSIS
use LaTeX::Encode;
$latex = latex_encode($text, %options);
VERSION
This manual page describes version 0.03 of the "LaTeX::Encode" module.
DESCRIPTION
This module provides a function to encode text that is to be formatted with LaTeX. It encodes characters that are special to LaTeX or that
are represented in LaTeX by LaTeX commands.
The special characters are: "" (command character), "{" (open group), "}" (end group), "&" (table column separator), "#" (parameter
specifier), "%" (comment character), "_" (subscript), "^" (superscript), "~" (non-breakable space), "$" (mathematics mode).
Note that some of the LaTeX commands for characters are defined in the LaTeX "textcomp" package. If your text includes such characters,
you will need to include the following lines in the preamble to your LaTeX document.
usepackage[T1]{fontenc}
usepackage{textcomp}
The function is useful for encoding data that is interpolated into LaTeX document templates, say with "Template::Plugin::Latex" (shameless
plug!).
SUBROUTINES /METHODS
"latex_encode($text, %options)"
Encodes the specified text such that it is suitable for processing with LaTeX. The behaviour of the filter is modified by the options:
"except"
Lists the characters that should be excluded from encoding. By default no special characters are excluded, but it may be useful to
specify "except = "\{}"" to allow the input string to contain LaTeX commands such as "this is \textbf{bold} text" (the doubled
backslashes in the strings represent Perl escapes, and will be evaluated to single backslashes).
"iquotes"
If true then single or double quotes around words will be changed to LaTeX single or double quotes; double quotes around a phrase
will be converted to "``" and "''" and single quotes to "`" and "'". This is sometimes called "intelligent quotes"
"use_textcomp"
By default the "latex_encode" filter will encode characters with the encodings provided by the "textcomp" LaTeX package (for
example the Pounds Sterling symbol is encoded as "\textsterling{}"). Setting "use_textcomp = 0" turns off these encodings. NOT
YET IMPLEMENTED
EXAMPLES
The following snippet shows how data from a database can be encoded and inserted into a LaTeX table, the source of which is generated with
"LaTeX::Table".
my $sth = $dbh->prepare('select col1, col2, col3 from table where $expr');
$sth->execute;
while (my $href = $sth->fetchrow_hashref) {
my @row;
foreach my $col (qw(col1 col2 col3)) {
push(@row, latex_encode($href->{$col}));
}
push @data, @row;
}
my $headings = [ [ 'Col1', 'Col2', 'Col3' ] ];
my $table = LaTeX::Table->new( { caption => 'My caption',
label => 'table:caption',
type => 'xtab',
header => $header,
data => @data } );
my $table_text = $table->generate_string;
Now $table_text can be interpolated into a LaTeX document template.
DIAGNOSTICS
None. You could probably break the "latex_encode" function by passing it an array reference as the options, but there are no checks for
that.
CONFIGURATION AND ENVIRONMENT
Not applicable.
DEPENDENCIES
The "HTML::Entities" and "Pod::LaTeX" modules were used for building the encoding table in "LaTeX::Encode::EncodingTable", but this is not
rebuilt at installation time. The "LaTeX::Driver" module is used for formatting the character encodings reference document.
INCOMPATIBILITIES
None known.
BUGS AND LIMITATIONS
Not all LaTeX special characters are included in the encoding tables (more may be added when I track down the definitions).
The "use_textcomp" option is not implemented.
