* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+5
| | | | | | | Relicense files for which I am the sole author (as identified by util/relicense.pl). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Use PRODUCT_SHORT_NAME for end-user visible stringsMichael Brown2015-02-111-1/+2
| | | | | | | | | | | Use PRODUCT_SHORT_NAME instead of a hardcoded "iPXE" for strings which are typically shown in the user interface. Note that this only allows for customisation of the user interface. Where the "iPXE" string serves a technical purpose (such as in the HTTP User-Agent), the string cannot be customised.

* [cmdline] Add support for shell historyMichael Brown2011-03-301-1/+10
| | | | | | | The up and down arrow keys will now function roughly as expected at the iPXE command line. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [parseopt] Refer to online documentation for command helpMichael Brown2011-03-041-2/+1Star
| | | | | | | | | | The online documentation (e.g. http://ipxe.org/cmd/ifopen), though not yet complete, is far more comprehensive than could be provided within the iPXE binary. Save around 200 bytes (compressed) by removing the command descriptions from the interactive help, and instead referring users directly to the web page describing the relevant command.

* [cmdline] Match user expectations for &&, ||, goto, and exitMichael Brown2010-11-291-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The && and || operators should be left-associative, since that is how they are treated in most other languages (including C and Unix shell). For example, in the command: dhcp net0 && goto dhcp_ok || echo No DHCP on net0 if the "dhcp net0" fails then the "echo" should be executed. After an "exit" or a successful "goto", further commands on the same line should never be executed. For example: goto somewhere && echo This should never be printed exit 0 && echo This should never be printed exit 1 && echo This should never be printed An "exit" should cause the current shell or script to terminate and return the specified exit status to its caller. For example: chain test.ipxe && echo Success || echo Failure [in test.ipxe] #!ipxe exit 0 should echo "Success". Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [shell] Add "shell" commandMichael Brown2010-11-281-2/+45
| | | | | | | The "shell" command allows a script to enter an interactive shell, which is potentially useful for troubleshooting. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [build] Rename gPXE to iPXEMichael Brown2010-04-201-3/+3
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.

* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-181-0/+2
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [tables] Redefine methods for accessing linker tablesMichael Brown2009-03-131-6/+1Star
| | | | | | | | | | | | | | | Intel's C compiler (icc) chokes on the zero-length arrays that we currently use as part of the mechanism for accessing linker table entries. Abstract away the zero-length arrays, to make a port to icc easier. Introduce macros such as for_each_table_entry() to simplify the common case of iterating over all entries in a linker table. Represent table names as #defined string constants rather than unquoted literals; this avoids visual confusion between table names and C variable or type names, and also allows us to force a compilation error in the event of incorrect table names.

* Use stdio.h instead of vsprintf.hMichael Brown2007-01-191-1/+1

* Add "name" field to struct device to allow human-readable hardware deviceMichael Brown2007-01-101-2/+4
| | | | | | | | | | | names. Add "dev" pointer in struct net_device to tie network interfaces back to a hardware device. Force natural alignment of data types in __table() macros. This seems to prevent gcc from taking the unilateral decision to occasionally increase their alignment (which screws up the table packing).
* Only need printf(), so use vsprintf.h instead of console.hMichael Brown2006-12-201-1/+1
