Overview of GUI elements
|
||||
|
||||
The window is separated into three main areas:
|
||||
- Connection to xorriso.
|
||||
- Management of drives and image files.
|
||||
- Inspection, manipulation, and exploitation of xorriso ISO image model.
|
||||
|
||||
------------------------------------------------------------------------
|
||||
|
||||
Connection to xorriso
|
||||
|
||||
The "End" button leads to the end of frontend and xorriso process.
|
||||
|
||||
The ready/busy field indicates whether a xorriso command is being executed
|
||||
and the frontend is still waiting for its reply messages.
|
||||
|
||||
The "Command:" field can be used to send commands to xorriso.
|
||||
|
||||
The "Refresh state display" button causes the other two main areas to update
|
||||
their display after manually transmitted commands may have changed the state
|
||||
of drives or ISO model.
|
||||
|
||||
The "Log pipes" switch controls whether all xorriso commands and replies
|
||||
shall be logged to standard error resp. to the file that has been iven
|
||||
with program argumen --log_file. Caution: This log is verbous.
|
||||
|
||||
The message box displays commands sent to xorriso and messages recieved
|
||||
from xorriso.
|
||||
Many commands which are emitted by the GUI will hide themselves and their
|
||||
replies from this display.
|
||||
All event messages with severity WARNING or higher will show up, nevertheless.
|
||||
|
||||
The "Recent problem:" field shows the most severe event message that occured
|
||||
during the execution of the most recent command. It also displays the most
|
||||
recent problem message from the frontend program itself.
|
||||
Several commands emitted by the GUI will not clear this display. But any
|
||||
manually transmitted command and the major GUI gestures will do.
|
||||
|
||||
The "Worst problem:" field shows the most severe event message that occured
|
||||
since last time the "Clear" button was hit. It will not clear automatically.
|
||||
|
||||
|
||||
------------------------------------------------------------------------
|
||||
|
||||
Management of drives and image files
|
||||
|
||||
The "Scan for drives" button executes command -devices and puts the list
|
||||
of found optical drives into the box underneath the button.
|
||||
|
||||
The "Pick input drive" button executes command -indev and obtains some
|
||||
information about the medium status. This info is displayed in the
|
||||
"Input drive or image" line.
|
||||
Further it causes the display of the ISO image model to be updated.
|
||||
|
||||
The "Pick output drive" button executes command -outdev and displays the
|
||||
related info in the "Output drive or image" line.
|
||||
|
||||
The "Pick drive for both roles" button executes command -dev and displays
|
||||
info in both "... drive or image" lines.
|
||||
|
||||
The "Give up drives" executes commands -indev "" -outdev "" and clears
|
||||
both "... drive or image" lines, as well as the ISO model.
|
||||
|
||||
The "Calm drives" button executes command -calm_drives which tells the
|
||||
aquired optical drives to stop spinning until the next drive activity
|
||||
gets triggered.
|
||||
|
||||
The "Rollback" button excutes command -rollbackwhich drops all pending
|
||||
changes of the ISO model and reloads it from the input drive, if one is
|
||||
aquired.
|
||||
|
||||
The box underneath these buttons shows the optical drives found by the
|
||||
"Can for drives" button.
|
||||
A double-click on a drive item has the same effect as button "Pick drive
|
||||
for both roles".
|
||||
|
||||
The line "Input drive or image" displays address and medium status of
|
||||
the input drive.
|
||||
Its "Eject" button excutes command -eject "in".
|
||||
Editing the drive address and pressing the Return key causes the execution
|
||||
of command -indev with the field content as drive address. Use this to
|
||||
load the model from ISO image data files on hard disk.
|
||||
|
||||
The line "Output drive or image" does about the same for the output drive.
|
||||
The text input field can be used to address an existing ISO image data
|
||||
file or to address a data file that does not yet exist. In the latter
|
||||
case, the ,edium status will be blank.
|
||||
|
||||
The "Blank" button executes command -blank "as_needed" on the output drive.
|
||||
This also applies to ISO image data files, which will get invalidated by
|
||||
a small write operation.
|
||||
|
||||
The "Format" button executes -format "as_needed".
|
||||
This only applies to real optical drives and s of interest only with DVD-RW
|
||||
or BD-R media, which both can be used formatted and unformatted. Other media
|
||||
types which mandatorily need formatting will be formatted by the write
|
||||
commands.
|
||||
|
||||
The "Write ISO session" executes command -commit, which writes a session
|
||||
with all pending changes to the output drive. The output drive must be
|
||||
either blank or it must be the same as the input drive.
|
||||
|
||||
The "Close" switch controls whether command -close "on" is emitted with
|
||||
"Write ISO session" or whether -as cdrecord option -multi is omitted with
|
||||
"Burn image file:".
|
||||
|
||||
The "TAO" switch controls whether an incremental write type shall be
|
||||
enforced with write commands. Normally xorriso will decide by medium status
|
||||
and job parameters which write type to choose.
|
||||
|
||||
The "Defect Mgt" switch controls whether slow and error-prone drive internal
|
||||
check reading shall be enabled with formatted BD-R or with BD-RE.
|
||||
|
||||
The "Burn image file:" button executes command -as "cdrecord" with the
|
||||
content of its text field as disk file address of a data file that is
|
||||
to be written to the output drive.
|
||||
The medium in the drive may be blank or appendable.
|
||||
|
||||
|
||||
------------------------------------------------------------------------
|
||||
|
||||
Inspection, manipulation, and exploitation of xorriso ISO image model
|
||||
|
||||
The "Extract to disk:" button executes command -extract with the whole
|
||||
tree of the current ISO directory or with the selected items of the box
|
||||
underneath "ISO directory:".
|
||||
This copies the selected files or directory trees from the input drive
|
||||
to the address on hard disk which is given by the text filed right of
|
||||
the button.
|
||||
|
||||
The "Underneath" switch controls the effective hard disk address of an item
|
||||
if the address in the text field points to a directory. If "Underneath"
|
||||
is enabled, then the file object from the ISO filesystem will be copied to its
|
||||
name underneath the hard disk directory.
|
||||
If "Underneath" is disabled then an ISO directory tree item will be merged
|
||||
with the disk directory tree at the given address.
|
||||
Example:
|
||||
Selected are "/iso_dir" and "/iso_file".
|
||||
Address for hard disk is "/tmp/from_iso". Switch "Selected" is enabled.
|
||||
"Underneath" enabled causes commands:
|
||||
-extract /iso_dir /tmp/from_iso/iso_dir
|
||||
-extract /iso_file /tmp/from_iso/iso_file
|
||||
"Underneath" disabled:
|
||||
-extract /iso_dir /tmp/from_iso
|
||||
-extract /iso_file /tmp/from_iso
|
||||
The last command will fail because /tmp/from_iso already exists as directory.
|
||||
|
||||
The "Selected" switch controls whether the whole current ISO directory,
|
||||
or only the selected items shall be copied to to hard disk.
|
||||
|
||||
The "Overwrite files" switch controls whether existing files may be
|
||||
overwritten in the ISO image or by extraction on hard disk.
|
||||
The frontend program will only detect the most obvious name collisions,
|
||||
but xorriso will reliably refuse to overwrite files if this is banned.
|
||||
|
||||
The "Overwrite ISO dirs" switch controls whether it is allowed to replace
|
||||
an ISO directory by a non-directory file.
|
||||
If a directory is copied to a directory, then both directory trees will
|
||||
be merged. So this switch applies only to situations where non-directories
|
||||
hit directories.
|
||||
|
||||
The "Enforce disk dir write access" switch enables the options "auto_chmod_on"
|
||||
and "sort_lba_on". "auto_chmod_on" allows xorriso to give itself temporariy
|
||||
w-permission to all disk directories which are owned by the xorriso user.
|
||||
This is not without dangers, of course, but comes in handy with restoring of
|
||||
backups.
|
||||
Option "sort_lba_on" reduces head-moves of optical drives and thus can
|
||||
speed up extraction substantially. It is bound to "auto_chmod_on" because
|
||||
else it might get in trouble when restoring ISO directories which offer
|
||||
no w-permission.
|
||||
|
||||
The "Refresh avail:" button triggers a time consuming exact prediction
|
||||
of the free space on the medium in the output drive. For this purpose,
|
||||
the size of an ISO session with the pending changes is computed.
|
||||
With image files rather than real optical drives, the free space of
|
||||
the hosting filesystem is displayed.
|
||||
|
||||
The "Insert from disk:" button executes command -map with the disk file
|
||||
address that is given by the text field right to the button.
|
||||
|
||||
The switch "Underneath" has the same effect as with file extraction:
|
||||
If enabled, a directory from disk will not be unpacked to its single files
|
||||
but put underneath the target address by its own leaf name.
|
||||
If the switch "Selected" is enabled, then the given disk file or tree will
|
||||
be inserted at or underneath the only selected item in the box inderneath
|
||||
"ISO directory:".
|
||||
|
||||
The text field in the "ISO directory:" line displays the current ISO
|
||||
directory and can be used to toggle its path directly. Hitting the
|
||||
Return key causes the current directory to change and the display in
|
||||
the box underneath to be refreshed.
|
||||
|
||||
The "Up" buttons move the current ISO directory one directory level up.
|
||||
|
||||
The "Verify" button executes -md5_check_r "SORRY" with the current ISO
|
||||
directory. ISO images bear MD5s for each data file if they were produced
|
||||
by xorriso with -md5 "on" resp. -for_backup. This frontend enables this
|
||||
feature on startup.
|
||||
|
||||
The list box underneath the "ISO directory:" line displays the files in
|
||||
the current ISO directory. One or more item can be selected and play a
|
||||
role with extraction or insertion of files.
|
||||
Most of the buttons underneath the box operate on the selected items
|
||||
unconditionally.
|
||||
|
||||
The "Verify" button in the "ISO selection:" line executes command
|
||||
-md5_check_r "SORRY" with each of the selected items.
|
||||
|
||||
The "Delete" button executes command -rm_r with each of the selected items.
|
||||
|
||||
The "Rename to:" button iuses command -mv to move each of the selected
|
||||
items to the address that is given by the text field right to the button.
|
||||
If this address points to an existing ISO directory, then the items will
|
||||
be moved underneath that directory and keep their leaf names.
|
||||
Else there may be only one selected item which will be renamed to the
|
||||
given address.
|
||||
|
||||
The "Make dir" button executes command -mkdir with the address in the
|
||||
text field to its left (the same as used by "Rename to:"). Useful to
|
||||
create a target directory before moving the selection.
