Version 20181118.
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:
clearFolder
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 limit. 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 $nomsg parameter.
dateTimeStamp
Year-monthNumber-day at hours:minute:seconds
filePathExt
Create a file name from an array of file name components the last of which is an extension. Identical to fpe.
fn
Remove path and extension from file name.
formatTable
Format various data structures as a table. Optionally create a report from the table using the following optional report options:
file=>$file the name of a file to write the report to.
head=>$head a header line in which DDDD will be replaced with the data and time and NNNN will be replaced with the number of rows in the table.
zero=>$zero if true the report will be written to the specified file even if empty.
Parameters:
genHash
Return a $blessed hash with the specified $attributes accessible via lvalue 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.
newProcessStarter
Create a new process starter with which to start parallel processes up to a specified $maximumNumberOfProcesses maximum number of parallel processes at a time, wait for all the started processes to finish and then optionally retrieve their saved results as an array from the folder named by $transferArea.
readFile
Read a file containing unicode in utf8.
searchDirectoryTreesForMatchingFiles
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 extension is supplied then all the files below the specified paths are returned.
sumAbsAndRel
Combine zero or more absolute and relative file names
writeFile
Write a unicode utf8 string to a new file that does not already exist after creating a path to the file if necessary and return the name of the file on success else confess if a problem occurred or the file does already exist.
xxx
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. If such a regular expression is not supplied then the command and its non blank output lines are always printed.
Date and timestamps as used in logs of long running commands.
Example:
ok 𝗱𝗮𝘁𝗲𝗧𝗶𝗺𝗲𝗦𝘁𝗮𝗺𝗽 =~ m(\A\d{4}-\d\d-\d\d at \d\d:\d\d:\d\d\Z);

Update 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.
