Ran Benita c79c8033 2019-11-09T21:25:01 atom: combine atom_intern() and atom_lookup() Use an "add" bool parameter instead. This simplifies the code a bit. Signed-off-by: Ran Benita <ran@unusedvar.com>
Ran Benita 2af474e8 2019-11-02T13:31:44 parser: get rid of "stealing" atoms This requires (well, at least implemented by) casting away `const` which is undefined behavior, and clang started to warn about it. The micro optimization didn't save too many allocations, anyway. Signed-off-by: Ran Benita <ran@unusedvar.com>
Ran Benita 58345f4e 2013-12-02T14:14:41 atom: drop {xkb_,}atom_strdup Even though in 112cccb18ad1bc877b3c4a87fa536ea085c761b5 I said it might be useful, it's not. So remove it. Signed-off-by: Ran Benita <ran234@gmail.com>
Ran Benita 7e0ae4b4 2013-07-21T16:41:27 atom: allow interning non-NUL-terminated strings We need this later. The strlen was calculated anyway, so no loss here. Signed-off-by: Ran Benita <ran234@gmail.com>
Ran Benita 9cd29453 2013-07-21T16:32:21 atom: expand variable names A bit easier to understand at a glance. Signed-off-by: Ran Benita <ran234@gmail.com>
Ran Benita b2110705 2012-09-16T14:45:32 Organize src/ and test/ headers - Add context.h and move context-related functions from xkb-priv.h to it. - Move xkb_context definition back to context.c. - Add keysym.h and move keysym upper/lower/keypad from xkb-priv.h to it. - Rename xkb-priv.h to map.h since it only contains keymap-related definitions and declarations now. - Remove unnecessary includes and some and some other small cleanups.

Clean up my copyright declarations (in some cases to correct ownership), and add copyright/license statements from myself and/or Ran where appropriate.

Ran Benita 7aa31097 2012-08-31T18:52:26 atom: add xkb_atom_lookup This will only lookup the string and return the atom if found; it will not intern it if not. This is useful when e.g. getting a string from the user (which may be arbitrary) and comparing against atoms. Signed-off-by: Ran Benita <ran234@gmail.com>
Ran Benita 112cccb1 2012-07-23T16:03:34 Some atom related optimizations We often get a strdup'd string, just to pass it over the atom_intern and then immediately free it. But atom_intern then strdup's it again (if it's not interned already); so instead we can have the interning "steal" the memory instead of allocing a new one and freeing the old one. This is done by a new xkb_atom_steal function. It also turns out, that every time we strdup an atom, we don't actually modify it afterwards. Since we are guaranteed that the atom table will live as long as the context, we can just use xkb_atom_text instead. This removes a some more dynamic allocations. For this change we had to remove the ability to append two strings, e.g. "foo" + "bar" -> "foobar" which is only possible with string literals. This is unused and quite useless for our purposes. xkb_atom_strdup is left unused, as it may still be useful.

Daniel Stone 9308a460 2012-07-17T10:20:15 Run source tree through uncrustify .uncrustify.cfg committed for future reference also, but had to manually fix up a few things: it really likes justifying struct initialisers. Signed-off-by: Daniel Stone <daniel@fooishbar.org>
Ran Benita 699a0b84 2012-05-09T14:02:26 Contextualize the atom table Each context gets its own table, i.e. interning a string in one context does not affect any other context. The existing xkb_atom_* functions are turned into wrappers around a new standalone atom_table object. Signed-off-by: Ran Benita <ran234@gmail.com> [daniels: Updated for xkb -> keymap.]
Ran Benita cdd2906d 2012-05-09T13:50:05 Make the context available for XkbcAtomText And rename the function to xkb_atom_text. Signed-off-by: Ran Benita <ran234@gmail.com> [daniels: Updated for xkb -> keymap.]
Ran Benita 8d680e80 2012-05-09T12:01:03 Make the context available for XkbcAtomGetString In preparation of contextualizing atom handling. Since we touch every function call, we also rename the function to xkb_atom_strdup to match xkb_atom_intern, and be more descriptive.

Ran Benita c117318f 2012-05-09T11:47:20 Make the context available to xkb_intern_atom In preparation of contextualizing the atom table. Since we touch every function call, also rename the function to xkb_atom_intern, to match better with the rest (which will also be renamed). Signed-off-by: Ran Benita <ran234@gmail.com> [daniels: Fixed for 'xkb' -> 'keymap'.]
Ran Benita b610b2b9 2012-05-08T14:52:23 Rename XKBcommonint.h to xkb-priv.h and use it Make the files in the src/* directory use their own header or a consilidated private header. This makes the file dependencies clearer. Also drop the pointless "xkb" file name prefix, add split a few declarations to their own files (atom.h and text.h).
