Attributes
rather than draw graphics lines around boxes, draw ASCII + and -
This gives you some control over the box dimensions when using auto sizing (specifying 0 for height and width). It represents width / height. The default is 9, which means 9 characters wide to every 1 line high.
Specifies a backtitle string to be displayed on the backdrop, at the top of the screen.
Sound the audible alarm each time the screen is refreshed.
Specify the position of the upper left corner of a dialog box on the screen, as an array containing two integers.
Override the label used for “Cancel” buttons
clear screen
Interpret embedded newlines in the dialog text as a newline on the screen. Otherwise, dialog will only wrap lines where needed to fit inside the text box. Even though you can control line breaks with this, dialog will still wrap any lines that are too long for the width of the box. Without cr-wrap, the layout of your text may be formatted to look nice in the source code of your script without affecting the way it will look in the dialog.
exit codes
pass dialog's option exactly
Override the label used for the “Extra” button
Override the label used for the “Help” button
make the password widget friendlier but less secure, by echoing asterisks for each character.
Interpret the tags data for checklist, radiolist and menuboxes adding a column which is displayed in the bottom line of the screen, for the currently selected item.
ruby logger
Override the label used for “No” buttons
Suppress the “Cancel” button in checklist, inputbox and menubox modes. A script can still test if the user pressed the ESC key to cancel to quit.
Override the label used for “OK” buttons
set it to true for passwordform.
Alternate path to dialog. If this is not set, environment path is used.
Specify the rc file to use for dialog. Default is $HOME/.dialogrc
For widgets holding a scrollable set of data, draw a scrollbar on its right-margin. This does not respond to the mouse.
Draw a shadow to the right and bottom of each dialog box.
Sleep (delay) for the given integer of seconds after processing a dialog box.
Convert each tab character to one or more spaces. Otherwise, tabs are rendered according to the curses library's interpretation.
Specify the number(int) of spaces that a tab character occupies if the tabcorrect option is set true. The default is 8.
Title string to be displayed at the top of the dialog box.
Override the label used for “Yes” buttons

A buildlist dialog displays two lists, side-by-side. The list on the left shows unselected items. The list on the right shows selected items. As items are selected or unselected, they move between the lists. Use SPACE bar to select/unselect an item.
Use a carriage return or the “OK” button to accept the current value in the selected-window and exit. The results are written using the order displayed in the selected-window.
The caller is responsile to create the items properly. Please look at samples/buildlist.rb for an example.
return an array of selected tags

A calendar box displays month, day and year in separately adjustable windows. If the values for day, month or year are missing or negative, the current date's corresponding values are used. You can increment or decrement any of those using the left-, up-, right- and down-arrows. Use vi-style h, j, k and l for moving around the array of days in a month. Use tab or backtab to move between windows. If the year is given as zero, the current date is used as an initial value.
Returns a Date object with the selected date
# File lib/mrdialog/mrdialog.rb, line 747 def calendar(text="Select a Date", height=0, width=0, day=Date.today.mday(), month=Date.today.mon(), year=Date.today.year()) tmp = Tempfile.new('tmp') command = option_string() + "--calendar \"" + text.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " + day.to_i.to_s + " " + month.to_i.to_s + " " + year.to_i.to_s + " 2> " + tmp.path success = system(command) @exit_code = $?.exitstatus if success date = Date::civil(*tmp.readline.split('/').collect {|i| i.to_i}.reverse) tmp.close! return date else tmp.close! return success end end
A checklist box is similar to a menu box; there are multiple entries presented in the form of a menu. Instead of choosing one entry among the entries, each entry can be turned on or off by the user. The initial on/off state of each entry is speci- fied by status. return an array of selected items
# File lib/mrdialog/mrdialog.rb, line 774 def checklist(text, items, height=0, width=0, listheight=0) tmp = Tempfile.new('tmp') itemlist = String.new for item in items if item[2] item[2] = "on" else item[2] = "off" end itemlist += "\"" + item[0].to_s + "\" \"" + item[1].to_s + "\" " + item[2] + " " if @itemhelp itemlist += "\"" + item[3].to_s + "\" " end end sep = "|" command = option_string() + "--checklist \"" + text.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " + listheight.to_i.to_s + " " + itemlist + "2> " + tmp.path log_debug "Command:\n#{command}" success = system(command) @exit_code = $?.exitstatus selected_array = [] if success selected_string = tmp.readline tmp.close! log_debug "Separator: #{@separator}" sep = Shellwords.escape(@separator) a = selected_string.split(/#{sep}/) a.each do |item| log_debug ">> #{item}" selected_array << item if item && item.to_s.length > 0 end return selected_array else tmp.close! return success end end
The edit-box dialog displays a copy of the file. You may edit it using the backspace, delete and cursor keys to correct typing errors. It also recognizes pageup/pagedown. Unlike the –in- putbox, you must tab to the “OK” or “Cancel” buttons to close the dialog. Pressing the “Enter” key within the box will split the corresponding line.
On exit, the contents of the edit window are written to dialog's output.
# File lib/mrdialog/mrdialog.rb, line 579 def editbox(filepath, height=0, width=0) tmp = Tempfile.new('dialog') cmd = "" cmd << option_string() cmd << " " cmd << "--editbox" cmd << " " cmd << '"' cmd << filepath cmd << '"' cmd << " " cmd << height.to_s cmd << " " cmd << width.to_s cmd << " " cmd << "2>" cmd << tmp.path log_debug "Command:\n#{cmd}" system(cmd) result = '' @exit_code = $?.exitstatus log_debug "Exit code: #{exit_code}" if @exit_code == 0 result = tmp.read end tmp.close! return result end
return the exit code of the dialog
# File lib/mrdialog/mrdialog.rb, line 222 def exit_code return @exit_code end
form/mixedform dialog A form dialog displays a form consisting of labels and fields, which are positioned on a scrollable window by coordinates given in the script. The field length flen and input-length ilen tell how long the field can be. The former defines the length shown for a selected field, while the latter defines the permissible length of the data entered in the field.
The caller is responsile to create the items properly. Please look at samples/form.rb for an example
return a hash. keys are the labels

Here filepath can be a filepath in which case the file and directory windows will display the contents of the path and the text-entry window will contain the preselected filename.
Use tab or arrow keys to move between the windows. Within the directory or filename windows, use the up/down arrow keys to scroll the current selection. Use the space-bar to copy the current selection into the text-entry window.
Typing any printable characters switches focus to the text- entry window, entering that character as well as scrolling the directory and filename windows to the closest match.
Use a carriage return or the “OK” button to accept the current value in the text-entry window and exit.
# File lib/mrdialog/mrdialog.rb, line 842 def fselect(path, height=0, width=0) tmp = Tempfile.new('tmp') command = option_string() + "--fselect \"" + path.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " command += "2> " + tmp.path success = system(command) @exit_code = $?.exitstatus if success begin selected_string = tmp.readline rescue EOFError selected_string = "" end tmp.close! return selected_string else tmp.close! return success end end
A gauge box displays a meter along the bottom of the box. The
meter indicates the percentage. New percentages are read from standard input, one integer per line. The meter is updated to reflect each new percentage. If the standard input reads the string “XXX”, then the first line following is taken as an integer percentage, then subsequent lines up to another “XXX” are used for a new prompt. The gauge exits when EOF is reached on the standard input.
The percent value denotes the initial percentage shown in the meter. If not speciied, it is zero.
On exit, no text is written to dialog's output. The widget accepts no input, so the exit status is always OK.
The caller will write the text markers to stdout as described above inside a block and will pass the block to the method. Look at samples/gauge for an example on how the method is called. Thanks to Mike Morgan for the idea to use a block.

# File lib/mrdialog/mrdialog.rb, line 273 def gauge(text, height=0, width=0, percent=0) cmd = "" cmd << option_string() cmd << " " cmd << "--gauge" cmd << " " cmd << '"' cmd << text cmd << '"' cmd << " " cmd << height.to_s cmd << " " cmd << width.to_s cmd << " " cmd << percent.to_s log_debug "Command:\n#{cmd}" IO.popen(cmd, "w") {|fh| yield fh} end
An info box is basically a message box. However, in this case, dialog will exit immediately after displaying the message to the user. The screen is not cleared when dialog exits, so that the message will remain on the screen until the calling shell script clears it later. This is useful when you want to inform the user that some operations are carrying on that may require some time to finish.
Returns false if esc was pushed
# File lib/mrdialog/mrdialog.rb, line 878 def infobox(text, height=0, width=0) command = option_string() + "--infobox \"" + text.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " success = system(command) @exit_code = $?.exitstatus return success end
An input box is useful when you want to ask questions that require the user to input a string as the answer. If init is supplied it is used to initialize the input string. When entering the string, the backspace, delete and cursor keys can be used to correct typing errors. If the input string is longer than can fit in the dialog box, the input field will be scrolled.
On exit, the input string will be returned.
# File lib/mrdialog/mrdialog.rb, line 1116 def inputbox(text="Please enter some text", height=0, width=0, init="") tmp = Tempfile.new('tmp') command = option_string() + "--inputbox \"" + text.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " unless init.empty? command += init.to_s + " " end command += "2> " + tmp.path log_debug(command) success = system(command) @exit_code = $?.exitstatus if success begin selected_string = tmp.readline rescue EOFError selected_string = "" end tmp.close! return selected_string else tmp.close! return success end end
if @logger is set, log
# File lib/mrdialog/mrdialog.rb, line 215 def log_debug(msg) if @logger @logger.debug("#{msg}") end end
A mixedform dialog displays a form consisting of labels and fields,
much like the –form dialog. It differs by adding a field-type parameter to each field's description. Each bit in the type denotes an attribute of the field:
-
1 hidden, e.g., a password field.
-
2 readonly, e.g., a label.#

# File lib/mrdialog/mrdialog.rb, line 716 def mixedform(text, items, height=0, width=0, formheight=0) item_size = items[0].size log_debug "Item size:#{item_size}" if item_size == 9 return form(text, items, height, width, formheight) end return nil end
A message box is very similar to a yes/no box. The only dif- ference between a message box and a yes/no box is that a mes- sage box has only a single OK button. You can use this dialog box to display any message you like. After reading the mes- sage, the user can press the ENTER key so that dialog will exit and the calling shell script can continue its operation.
# File lib/mrdialog/mrdialog.rb, line 982 def msgbox(text="Text Goes Here", height=0, width=0) command = option_string() + "--msgbox \"" + text.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " log_debug "Command\n#{command}" success = system(command) @exit_code = $?.exitstatus return success end
A password box is similar to an input box, except that the text the user enters is not displayed. This is useful when prompt- ing for passwords or other sensitive information. Be aware that if anything is passed in “init”, it will be visible in the system's process table to casual snoopers. Also, it is very confusing to the user to provide them with a default password they cannot see. For these reasons, using “init” is highly discouraged.
# File lib/mrdialog/mrdialog.rb, line 1001 def passwordbox(text="Please enter some text", height=0, width=0, init="") tmp = Tempfile.new('tmp') command = option_string() + "--passwordbox \"" + text.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " unless init.empty? command += init.to_s + " " end command += "2> " + tmp.path log_debug(command) success = system(command) @exit_code = $?.exitstatus if success begin selected_string = tmp.readline rescue EOFError selected_string = "" end tmp.close! return selected_string else tmp.close! return success end end
This is identical to –form except that all text fields are treated as password widgets rather than inputbox widgets.
# File lib/mrdialog/mrdialog.rb, line 728 def passwordform(text, items, height=0, width=0, formheight=0) @password_form = true return form(text, items, height, width, formheight) end
A pause box displays a meter along the bottom of the box. The meter indicates how many seconds remain until the end of the pause. The pause exits when timeout is reached or the user presses the OK button (status OK) or the user presses the CANCEL button or Esc key.
# File lib/mrdialog/mrdialog.rb, line 547 def pause(text="Text Goes Here", height=0, width=0, secs=10) cmd = "" cmd << option_string() cmd << " " cmd << "--pause" cmd << " " cmd << '"' cmd << text cmd << '"' cmd << " " cmd << height.to_s cmd << " " cmd << width.to_s cmd << " " cmd << secs.to_s log_debug "Command:\n#{cmd}" system(cmd) result = '' @exit_code = $?.exitstatus log_debug "Exit code: #{exit_code}" end
A prgbox is very similar to a programbox.
This dialog box is used to display the output of a command that is specified as an argument to prgbox.
After the command completes, the user can press the ENTER key so that dialog will exit and the calling shell script can continue its operation.
If three parameters are given, it displays the text under the title, delineated from the scrolling file's contents. If only two parameters are given, this text is omitted.
# File lib/mrdialog/mrdialog.rb, line 360 def prgbox(command, height=0, width=0, text='') cmd = "" cmd << option_string() cmd << " " cmd << "--prgbox" cmd << " " if text.length > 0 cmd << '"' cmd << text cmd << '"' end cmd << " " cmd << '"' cmd << command cmd << '"' cmd << " " cmd << height.to_s cmd << " " cmd << width.to_s system(cmd) @exit_code = $?.exitstatus end
same as progressbox but displays OK button at the end
# File lib/mrdialog/mrdialog.rb, line 326 def programbox(description='', height=0, width=0) cmd = "" cmd << option_string() cmd << " " cmd << "--programbox" cmd << " " if description.length > 0 cmd << '"' cmd << description cmd << '"' end cmd << " " cmd << height.to_s cmd << " " cmd << width.to_s log_debug("Command\n#{cmd}") IO.popen(cmd, "w") {|fh| yield fh} end
Progressbox is used to display the piped output of a command.
After the command completes, the user can press the ENTER key so that dialog will exit and the calling shell script can continue its operation. If three parameters are given, it displays the text under the title, delineated from the scrolling file's contents. If only two parameters are given, this text is omitted.
The caller will write the progress string on stdout in a block and will pass the block to the method. Please look at samples/ progress.rb for an example. Author: muquit@muquit.com Apr-02-2014
# File lib/mrdialog/mrdialog.rb, line 305 def progressbox(description='', height=0, width=0) cmd = "" cmd << option_string() cmd << " " cmd << "--progressbox" cmd << " " if description.length > 0 cmd << '"' cmd << description cmd << '"' end cmd << " " cmd << height.to_s cmd << " " cmd << width.to_s log_debug("Command\n#{cmd}") IO.popen(cmd, "w") {|fh| yield fh} end
A radiolist box is similar to a menu box. The only difference is that you can indicate which entry is currently selected, by setting its status to true.
# File lib/mrdialog/mrdialog.rb, line 889 def radiolist(text, items, height=0, width=0, listheight=0) tmp = Tempfile.new('tmp') itemlist = String.new for item in items if item[2] item[2] = "on" else item[2] = "off" end itemlist += "\"" + item[0].to_s + "\" \"" + item[1].to_s + "\" " + item[2] + " " if @itemhelp itemlist += "\"" + item[3].to_s + "\" " end end command = option_string() + "--radiolist \"" + text.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " + listheight.to_i.to_s + " " + itemlist + "2> " + tmp.path log_debug("Command:\n#{command}") success = system(command) @exit_code = $?.exitstatus if success selected_string = tmp.readline tmp.close! return selected_string else tmp.close! return success end end
The textbox method handles three similar dialog functions, textbox, tailbox, and tailboxbg. They are activated by setting type to "text", "tail", and "bg" respectively Textbox mode:
A text box lets you display the contents of a text file in a dialog box. It is like a simple text file viewer. The user can move through the file by using the cursor, PGUP/PGDN and HOME/END keys available on most keyboards. If the lines are too long to be displayed in the box, the LEFT/RIGHT keys can be used to scroll the text region horizontally. You may also use vi-style keys h, j, k, l in place of the cursor keys, and B or N in place of the pageup/pagedown keys. Scroll up/down using vi-style 'k' and 'j', or arrow-keys. Scroll left/right using vi-style 'h' and 'l', or arrow-keys. A '0' resets the left/right scrolling. For more convenience, vi-style forward and backward searching functions are also provided.
Tailbox mode:
Display text from a file in a dialog box, as in a “tail -f” command. Scroll left/right using vi-style 'h' and 'l', or arrow-keys. A '0' resets the scrolling.
Tailboxbg mode:
Display text from a file in a dialog box as a background task, as in a “tail -f &” command. Scroll left/right using vi-style 'h' and 'l', or arrow-keys. A '0' resets the scrolling.
# File lib/mrdialog/mrdialog.rb, line 1057 def textbox(file, type="text", height=0, width=0) case type when "text" opt = "--textbox" when "tail" opt = "--tailbox" when "bg" opt = "--textboxbg" end command = option_string() + opt +" \"" + file.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " success = system(command) @exit_code = $?.exitstatus return success end

# File lib/mrdialog/mrdialog.rb, line 1086 def timebox(text, height=0, width=0, time=Time.now) tmp = Tempfile.new('tmp') command = option_string() + "--timebox \"" + text.to_s + "\" " + height.to_i.to_s + " " + width.to_i.to_s + " " + time.hour.to_s + " " + time.min.to_s + " " + time.sec.to_s + " 2> " + tmp.path log_debug("Command:\n#{command}") success = system(command) @exit_code = $?.exitstatus if success time = Time.parse(tmp.readline) tmp.close! return time else tmp.close! return success end end
Display data organized as a tree. Each group of data contains a tag, the text to display for the item, its status (“on” or “off”) and the depth of the item in the tree.
Only one item can be selected (like the radiolist). The tag is not displayed.
On exit, the tag of the selected item is written to dialog's output.
# File lib/mrdialog/mrdialog.rb, line 393 def treeview(text="Text Goes Here", items=nil, height=0, width=0, listheight=0) tmp = Tempfile.new('dialog') itemlist = '' items.each do |item| itemlist << '"' itemlist << item[0].to_s itemlist << '"' itemlist << " " itemlist << '"' itemlist << item[1].to_s itemlist << '"' itemlist << " " itemlist << '"' if item[2] item[2] = "on" else item[2] = "off" end itemlist << item[2] itemlist << '"' itemlist << " " itemlist << item[3].to_s itemlist << " " end itemlist << "2>" itemlist << tmp.path cmd = "" cmd << option_string() cmd << " " cmd << "--treeview" cmd << " " cmd << '"' cmd << " " cmd << text cmd << '"' cmd << " " cmd << height.to_s cmd << " " cmd << width.to_s cmd << " " cmd << listheight.to_s cmd << " " cmd << itemlist log_debug "Number of items: #{items.size}" log_debug "Command:\n#{cmd}" system(cmd) @exit_code = $?.exitstatus log_debug "Exit code: #{exit_code}" tag = '' if @exit_code == 0 tag = tmp.read end tmp.close! return tag end
