return printable name of bootloader
- Parameters:
-
bootloader string bootloader type internal string mode symbol `combo or `summary (because of capitalization)
- Return value:
-
printable bootloader name
Get value of specified boolean bootloader attribute
- Parameters:
-
attrib string attribute name
- Return value:
-

Update the text of countdown widget
- Parameters:
-
bootloader string printable name of used bootloader
Get the list of installed floppy drives
- Return value:
-
a list of floppy devices
converts array of string to path
- Parameters:
-
strs list of string
- Return value:
-
whose components are taken from strs
Converts a "/dev/disk/by-" device name to the corresponding kernel device name, if a mapping for this name can be found in the map from yast2-storage. If the given device name is not a "/dev/disk/by-" device name, it is left unchanged. Also, if the information about the device name cannot be found in the target map from yast2-storage, the device name is left unchanged.
- Parameters:
-
dev string device name
- Return value:
-
kernel device name
Converts a device name to the corresponding device name it should be mounted by, according to the "mountby" setting for the device from yast2-storage. As a safeguard against problems, if the "mountby" device name does not exist in the information from yast2-storage, it will fallback to the "kernel name" ("/dev/hda1").
- Parameters:
-
dev string device name
- Return value:
-
device name according to "mountby"
Returns list of partitions with "mount by" hints. Goes through the list of partitions passed as a parameter and creates a list of partitions with hints according to the current partitioning requested from yast2-storage. To be used in a combobox or menu.
- Parameters:
-
parts_to_get list partitions to list
- Return value:
-
a list of strings containing a partition name and a hint (if applicable)
Returns list of partitions. Requests current partitioning from yast2-storage and creates list of partition for combobox, menu or other purpose.
- Parameters:
-
type symbol `boot - for bootloader installation `root - for kernel root `boot_other - for bootable partitions of other systems `all - all partitions `parts_old - all partitions, except those what will be created during isntallation `deleted - all partitions deleted in current proposal `kept - all partitions that won't be deleted, new created or formatted `destroyed - all partition which are new, deleted or formatted
- Return value:
-
a list of strings
returns true if char is blank (newline, tab or space)
- Parameters:
-
s single char string
- Return value:
-
blank/non blank
removes trailing and leading blank chars from string. eg: " as df " -> "as df"
- Parameters:
-
str string source string
- Return value:
-
stripped string
replaces all occurences of 'from' to 'to' in src
- Parameters:
-
src input string from string to be replaced to string to be replaced by
- Return value:
-
modified string
convert string values from agent representation to module representation 1) if string is quoted, quotes are removed 2) if string contains escaped quotes, they're unescaped
- Parameters:
-
val value to transform
- Return value:
-
transformed value
returns list difference A \ B (items that are in A and are not in B)
- Parameters:
-
a list A b list B
- Return value:
-
see above
returns modified list where items index1 and index2 are swapped. if indices are out of bounds, unmodified list is returned.
- Parameters:
-
input list index1 index of the first element index2 index og the second element
- Return value:
-
modified list
translate filename path (eg. /boot/kernel) to list of device and relative path
- Parameters:
-

- Return value:
-
a list containing device and relative path, eg. ["/dev/hda1", "/vmlinuz"]
Get bootloader device for specified location FIXME: this function is being phased out. Keeping it around until selected_location and loader_device can be dropped for all bootloader types.
