* [settings] Explicitly separate the concept of a completed fetched settingMichael Brown2013-12-053-45/+41Star
| | | | | | | | | | The fetch_setting() family of functions may currently modify the definition of the specified setting (e.g. to add missing type information). Clean up this interface by requiring callers to provide an explicit buffer to contain the completed definition of the fetched setting, if required. Signed-off-by: Michael Brown <mcb30@ipxe.org>

| | | | | | | | The "inc" command allows the numeric value of a setting to be incremented, allowing for the construction of simple loops within an iPXE script. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Eliminate calls to {fetch,store}f_named_setting() in NVO commandsMichael Brown2013-07-221-40/+56
| | | | | | | | | | | | | | | | | A deliberate side effect of this commit is that the "read" command will now preserve the type of the setting, if the setting name contains no type information. For example: iPXE> set foo:ipv4 192.168.0.1 iPXE> read foo 192.168.0.100 iPXE> show foo foo:ipv4 = 192.168.0.100 rather than the arguably unexpected behaviour of resetting the type to "string".

* [ifmgmt] Avoid relying on global variable within ifcommon_exec()Michael Brown2013-07-151-4/+3Star
| | | | | | | | | | | | | | | The getopt API defines optind as a global variable. When used by the "autoboot" command, the payload function passed to ifcommon_exec() may result in a new iPXE script being executed; the commands therein would then overwrite the value of optind. On returning, ifcommon_exec() would continue processing the list of interfaces from an undefined point. Fix by using a local variable to hold the index within the list of interfaces.

* [settings] Make "netX" settings block function as a symbolic linkMichael Brown2013-07-131-1/+1
| | | | | | | | | | | | | | Add a facility for settings blocks to act as symbolic links to other settings blocks, and reimplement the "netX" virtual settings block using this facility. The primary advantage of this approach is that unscoped settings such as ${mac} and ${filename} will now reflect the settings obtained from the most recently opened network device: in most cases, this will mean the settings obtained from the most recent DHCP attempt. This should improve conformance to the principle of least astonishment. Signed-off-by: Michael Brown <mcb30@ipxe.org>

| | | | | | | | | Abstract out the ability to reboot the system to a separate reboot() function (with platform-specific implementations), add an EFI implementation, and make the existing "reboot" command available under EFI. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [menu] Prevent separators with shortcut keys from being selectedMichael Brown2013-03-061-10/+12
| | | | | | | | | | | | | | | | | | | | | | | Nothing currently prevents a menu separator from being assigned a shortcut key, and then from being selected using that shortcut key. This produces an inconsistency in the user interface, since separators cannot be selected by other means of menu navigation (arrow keys, page up/down, etc). It would be trivial to prevent separators from being assigned shortcut keys, but this would eliminate one potentially useful use case: having a large menu and using shortcut keys to jump to a section within the menu. Fix by treating a shortcut key on a separator as equivalent to "select the separator, then press the down arrow key". This has the effect of moving to the first non-separator menu item following the specified separator, which is probably the most intuitive behaviour. (The existing logic for moving the selection already handles the various nasty corner cases such as a menu ending with one or more separators.)

* [menu] Prevent character code zero from acting as a shortcut keyMichael Brown2013-03-061-1/+2
| | | | | | | | | | | | Unrecognised keys may be returned by getkey() as character code zero, which currently matches against the first menu item with no shortcut key defined. Prevent this unintended behaviour by explicitly checking that the menu item has a defined shortcut key.

* [settings] Use a generic setting's own type as its default typeMichael Brown2012-09-102-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When fetching a named setting using a name that does not explicitly specify a type, default to using the type stored when the setting was created, rather than always defaulting to "string". This allows the behaviour of user-defined settings to match the behaviour of predefined settings (which have a sensible default type). For example: set server:ipv4 192.168.0.1 echo ${server} will now print "192.168.0.1", rather than trying to print out the raw IPv4 address bytes as a string. The downside of this change is that existing tricks for printing special characters within scripts may require (backwards-compatible) modification. For example, the "clear screen" sequence: set esc:hex 1b set cls ${esc}[2J echo ${cls} will now have to become set esc:hex 1b set cls ${esc:string}[2J # Must now explicitly specify ":string" echo ${cls} Signed-off-by: Michael Brown <mcb30@ipxe.org>
