Version 20211206.
The following sections describe the methods in each functional area of this module. For an alphabetic listing of all methods by name see Index.
These methods are the ones most likely to be of immediate use to anyone using this module for the first time:
absFromAbsPlusRel($a, $r)
Absolute file from an absolute file $a plus a relative file $r. In the event that the relative file $r is, in fact, an absolute file then it is returned as the result.
awsParallelProcessFiles($userData, $parallel, $results, $files, %options)
Process files in parallel across multiple Amazon Web Services instances if available or in series if not. The data located by $userData is transferred from the primary instance, as determined by awsParallelPrimaryInstanceId, to all the secondary instances. $parallel contains a reference to a sub, parameterized by array @_ = (a copy of the user data, the name of the file to process), which will be executed upon each session instance including the primary instance to update $userData. $results contains a reference to a sub, parameterized by array @_ = (the user data, an array of results returned by each execution of $parallel), that will be called on the primary instance to process the results folders from each instance once their results folders have been copied back and merged into the results folder of the primary instance. $results should update its copy of $userData with the information received from each instance. $files is a reference to an array of the files to be processed: each file will be copied from the primary instance to each of the secondary instances before parallel processing starts. %options contains any parameters needed to interact with EC2 via the Amazon Web Services Command Line Interface. The returned result is that returned by sub $results.
clearFolder($folder, $limitCount, $noMsg)
Remove all the files and folders under and including the specified $folder as long as the number of files to be removed is less than the specified $limitCount. Sometimes the folder can be emptied but not removed - perhaps because it a link, in this case a message is produced unless suppressed by the optional $nomsg parameter.
dateTimeStamp
Year-monthNumber-day at hours:minute:seconds.
execPerlOnRemote($code, $ip)
Execute some Perl $code on the server whose ip address is specified by $ip or returned by awsIp.
filePathExt(@File)
Create a file name from a list of names the last of which is assumed to be the extension of the file name. Identical to fpe.
fn($file)
Remove the path and extension from a file name.
formatTable($data, $columnTitles, @options)
Format various $data structures as a table with titles as specified by $columnTitles: either a reference to an array of column titles or a string each line of which contains the column title as the first word with the rest of the line describing that column.
Optionally create a report from the table using the report %options described in formatTableCheckKeys.
genHash($bless, %attributes)
Return a $blessed hash with the specified $attributes accessible via lvalue method method calls. updateDocumentation will generate documentation at "Hash Definitions" for the hash defined by the call to genHash if the call is laid out as in the example below.
readFile($file)
Return the content of a file residing on the local machine interpreting the content of the file as utf8.
readFileFromRemote($file, $ip)
Copy and read a $file from the remote machine whose ip address is specified by $ip or returned by awsIp and return the content of $file interpreted as utf8 .
relFromAbsAgainstAbs($a, $b)
Relative file from one absolute file $a against another $b.
runInParallel($maximumNumberOfProcesses, $parallel, $results, @array)
Process the elements of an array in parallel using a maximum of $maximumNumberOfProcesses processes. sub &$parallel is forked to process each array element in parallel. The results returned by the forked copies of &$parallel are presented as a single array to sub &$results which is run in series. @array contains the elements to be processed. Returns the result returned by &$results.
searchDirectoryTreeForSubFolders($folder)
Search the specified directory under the specified folder for sub folders.
searchDirectoryTreesForMatchingFiles(@FoldersandExtensions)
Search the specified directory trees for the files (not folders) that match the specified extensions. The argument list should include at least one path name to be useful. If no file extensions are supplied then all the files below the specified paths are returned. Arguments wrapped in [] will be unwrapped.
writeFile($file, $string)
Write to a new $file, after creating a path to the $file with makePath if necessary, a $string of Unicode content encoded as utf8. Return the name of the $file written to on success else confess if the file already exists or any other error occurs.
writeFileToRemote($file, $string, $ip)
Write to a new $file, after creating a path to the file with makePath if necessary, a $string of Unicode content encoded as utf8 then copy the $file to the remote server whose ip address is specified by $ip or returned by awsIp. Return the name of the $file on success else confess if the file already exists or any other error occurs.
xxxr($cmd, $ip)
Execute a command $cmd via bash on the server whose ip address is specified by $ip or returned by awsIp. The command will be run using the userid listed in .ssh/config.
Date and timestamps as used in logs of long running commands.

Execute a shell command optionally checking its response. The command to execute is specified as one or more strings which are joined together after removing any new lines. Optionally the last string can be a regular expression that is used to test any non blank output generated by the execution of the command: if the regular expression fails the command and the command output are printed, else it is suppressed as being uninteresting.

Normalize the name of the specified $source file to the md5 sum of its content, retaining its current extension, while placing the original file name in a companion file if the companion file does not already exist. If no $target folder is supplied the file is renamed to its normalized form in situ, otherwise it is copied to the target folder and renamed there. A companion file for the $source file is created by removing the extension of the normalized file and writing the original $source file name to it unless such a file already exists as we assume that it contains the 'original' original name of the $source file. If the $source file is copied to a new location then the companion file is copied as well to maintain the link back to the original name of the file.

Given $N buckets and a list @sizes of ([size of file, name of file]...) pack the file names into buckets so that each bucket contains approximately the same number of bytes. In general this is an NP problem. Packing largest first into emptiest bucket produces an N**2 heuristic if the buckets are scanned linearly, or N*log(N) if a binary tree is used. This solution is a compromise at N**3/2 which has the benefits of simple code yet good performance. Returns ([file names ...]).

Update the documentation for a Perl module from the comments in its source code. Comments between the lines marked with:
#Dn title # description
and:
#D
where n is either 1, 2 or 3 indicating the heading level of the section and the # is in column 1.
Methods are formatted as:
sub name(signature) #FLAGS comment describing method {my ($parameters) = @_; # comments for each parameter separated by commas.
FLAGS can be chosen from:
method of interest to new users
private method
optionally replaceable method
required replaceable method
static method
die rather than received a returned undef result
Other flags will be handed to the method extractDocumentationFlags(flags to process, method name) found in the file being documented, this method should return [the additional documentation for the method, the code to implement the flag].
Text following 'Example:' in the comment (if present) will be placed after the parameters list as an example. Lines containing comments consisting of '#T'.methodName will also be aggregated and displayed as examples for that method.
Lines formatted as:
BEGIN{*source=*target}
starting in column 1 will define a synonym for a method.
#C emailAddress text
will be aggregated in the acknowledgments section at the end of the documentation.
The character sequence \n in the comment will be expanded to one new line, \m to two new lines and L<$_>,L<confess>,L<die>,L<eval>,L<lvalueMethod> to links to the perl documentation.
Search for '#D1': in https://metacpan.org/source/PRBRENAN/Data-Table-Text-20180810/lib/Data/Table/Text.pm to see more examples of such documentation in action - although it is quite difficult to see as it looks just like normal comments placed in the code.
