Term::Clui::FileSelect3pm

Usage

 use Term::Clui::FileSelect;
 $file = &select_file(-Readable=>1, -TopDir=>"/home", -FPat=>"*.html");
 @files = &select_file(-Chdir=>0, -Path=>$ENV{PWD}, -FPat=>"*.mp3");
 chdir &select_file(-Directory=>1, -Path=>$ENV{PWD});

Overview

This module asks the user to select a file from the filesystem. It uses the Command-line user-interface Term::Clui to dialogue with the user. It offers Rescan and ShowAll buttons. To ease the re-learning burden for the programmer, the options are modelled on those of Tk::FileDialog and of Tk::SimpleFileSelect, but various new options are introduced, namely -TopDir, -TextFile, -Readable, -Writeable, -Executable, -Owned and -Directory

Multiple choice is possible in a limited circumstance; when file_select is invoked in a list context, with -Chdir=>0 and without -Create. It is currently not possible to select multiple files lying in different directories.

Subroutines

select_file( %options );

Options

-Chdir

Enable the user to change directories. The default is 1. If it is set to 0, and select_file is invoked in a list context, and -Create is not set, then the user can select multiple files.

-Create

Enable the user to specify a file that does not exist. The default is 0.

-ShowAll or -dotfiles

Determines whether hidden files (.*) are displayed. The default is 0.

-DisableShowAll

Disables the ability of the user to change the status of the ShowAll flag. The default is 0 (i.e. the user is by default allowed to change the status).

-SelDir

If True, enables selection of a directory rather than a file. The default is 0. To enforce selection of a directory, use the -Directory option.

-FPat or -filter

Sets the default file selection pattern, in glob format, e.g. *.html. Only files matching this pattern will be displayed. If you want multiple patterns, you can use formats like *.[ch] or {*.cgi,*.pl} - see File::Glob for more details. The default is "*".

-File

The file selected, or the default file. The default default is whatever the user selected last time in this directory.

-Path or -initialdir

The path of the selected file, or the initial path. The default is $ENV{HOME}.

-Title

The Title of the dialog box. If -Title is specified, then Clui::FileSelect dynamically appends "in /where/ever" to it. If -Title is not specified, Clui::FileSelect displays "in directory /where/ever".

-TopDir

Restricts the user to remain within a directory or its subdirectories. The default is "/". This option, and the following, are not offered by Tk::FileDialog.

-TextFile

Only text files will be displayed. The default is 0.

-Readable

Only readable files will be displayed. The default is 0.

-Writeable

Only writeable files will be displayed. The default is 0.

-Executable

Only executable files will be displayed. The default is 0.

-Owned

Only files owned by the current user will be displayed. This is useful if the user is being asked to choose a file for a chmod or chgrp operation, for example. The default is 0.

-Directory

Only directories will be displayed. The default is 0.
