apio	129e3c434a	Switch to C for userspace, with a very bare-bones libc!!	2023-01-06 13:31:14 +01:00

apio	fd8a0175d9	Add a syscall infrastructure (our baby program can print to the console now!)	2023-01-05 22:39:56 +01:00
apio	5854e5e530	Add newlines at end-of-file	2023-01-02 13:07:29 +01:00

apio	df8f9c6cf6	SharedPtr: adopt_shared_from_owned	2022-12-31 12:02:15 +01:00
apio	831711ab7e	TypeTraits: Remove const, volatile, and reference	2022-12-31 11:50:30 +01:00
apio	e2e21923d7	Result: Implement operator=()	2022-12-30 19:06:47 +01:00
apio	4081186b27	Heap: Rewrite kmalloc to use Option<HeapBlock*> instead of nullable pointers to iterate over the heap ... At some point, this should be done inside LinkedList itself, but we have no such thing as break in for_each(). It's iterate over everything or nothing. This also requires operator= in Option, might be also added to Result in the future.	2022-12-30 19:02:25 +01:00
apio	3a3968b268	Result: Add nonnull_or_error()	2022-12-30 18:46:27 +01:00
apio	973e39a255	LinkedList: Move nonnull_or_empty_option to Option.h so everyone can use it	2022-12-30 18:46:18 +01:00
apio	28f53f9ccf	LinkedList: Rename the nonnull_or_error() helper to a more accurate nonnull_or_empty_option()	2022-12-30 18:44:37 +01:00
apio	1f36ecd044	LinkedList: Make expect_first() and expect_last() show a more accurate error description on panic ... Instead of showing a generic "Option::value() called on an empty Option" with no useful source location, you will get something like "check failed: m_start_node at LinkedList.h:139"	2022-12-30 18:43:39 +01:00
apio	400d0395a2	Result: Avoid double-checking when calling through to the underlying Option	2022-12-30 15:00:02 +01:00

apio	f71ccde833	Add an overload for aligned deletes which just calls the normal operator delete	2022-12-24 11:49:12 +01:00
apio	e5ae2b0435	TarStream: Make read_contents and friends const	2022-12-23 13:08:31 +01:00
apio	ad0f6546d7	Add a global initrd TarStream to make the initial ramdisk accessible everywhere ... It's also mapped into virtual memory instead of directly going into the physical location!!	2022-12-23 11:33:23 +01:00
apio	c39e54b7c6	Make TarStream::read_contents take any pointer as output	2022-12-23 10:51:55 +01:00

apio	1269a045bd	LinkedList: Add a convenience delayed_for_each() method. ... This is a special way of iterating over the list which permits removing items while iterating.	2022-12-19 12:41:25 +01:00
apio	5b72144fac	Add a handy consume() method to LinkedList	2022-12-19 12:35:08 +01:00

apio	a08310ff5e	Add some more errno definitions	2022-12-18 18:09:52 +01:00
apio	cda0d49a4e	Add todo()	2022-12-18 17:15:42 +01:00
apio	4a7e48ed5d	Make sure wchar_t is wide enough to hold all Unicode code-points ... Too bad if it isn't.	2022-12-18 17:14:12 +01:00
apio	1d6092341a	Add a generic TarStream class ... As long as it's in memory, we can use it :)	2022-12-18 16:38:47 +01:00
apio	eadca3d25b	Add nullcpy() ... Invented function to memcpy() with a specific size, but add a null terminator.	2022-12-18 16:31:02 +01:00

apio	6389099808	UTF-8 part 2: Encoding wide-character strings into UTF-8 ... We now have Utf8StringEncoder and Utf8Encoder (no state this time)	2022-12-18 14:34:50 +01:00
apio	9c1c6bb320	Add wcslen() ... I think this can go in CString.h, no need to create a separate CWChar.h or something	2022-12-18 14:33:13 +01:00
apio	75ba14a3ad	Add UTF-8 decoder support!!	2022-12-18 13:04:40 +01:00

apio	ee6387e7b5	Refactor NumberParsing.cpp + a lot of comments	2022-12-17 15:00:19 +01:00
apio	97cb57d521	Check for overflow/underflow in parse_signed_integer	2022-12-17 14:42:56 +01:00
apio	acb0ab1cd7	Use TypeTraits in Alignment.h to make static assertions more readable	2022-12-17 13:50:27 +01:00
apio	ace674e518	LinkedList: Make sure the contained type inherits from DoublyLinkedListNode<T>	2022-12-17 13:49:47 +01:00
apio	2cbc9fa385	Add some nice TypeTraits	2022-12-17 13:48:55 +01:00
apio	16954695dd	Tell the compiler that string_format is a printf-style function	2022-12-17 12:45:26 +01:00
apio	16e00bada0	Add comments to Format.h	2022-12-17 12:43:29 +01:00
apio	abbed13f27	Add a 'pure' variant of cstyle_format which is infallible ... If we cannot fail to output, it doesn't make sense to propagate errors. So if you're SURE there are no errors, use pure_cstyle_format(). If, however, output can fail, use cstyle_format(). This has a drawback of adding quite a bit of code duplication to Format.cpp. Some of it is dealt using templates, but some code still remains duplicate.	2022-12-17 12:38:22 +01:00
apio	48fcb8734a	Give number parsing functions more meaningful names	2022-12-17 12:12:58 +01:00
apio	cf3b2176f0	Implement OwnedStringView::from_string_literal	2022-12-17 11:36:16 +01:00
apio	14461c6fe8	Atomic: Add operators += and -=	2022-12-17 10:49:19 +01:00
apio	a16f357ab9	Add an Atomic class	2022-12-16 21:15:22 +01:00
apio	da39ba33a9	Move OwnedStringView::operator[] out of line	2022-12-16 20:48:58 +01:00
apio	59765aa334	Rename String.h -> CString.h ... Let's not confuse String.h with a managed string class, it's in fact the equivalent of the C stdlib's <string.h>	2022-12-16 20:40:04 +01:00
apio	42a2c2af49	Add strdup()	2022-12-16 20:37:57 +01:00
apio	e56075fb46	Use nothrow in raw_malloc	2022-12-16 20:36:43 +01:00
apio	345e13965e	Add missing include ... No one was noticing because everyone using OwnedStringView included Result.h before it	2022-12-16 20:27:44 +01:00
apio	4a6c59d519	Make all methods in OwnedStringView const	2022-12-16 19:48:22 +01:00
apio	814672c771	Remove some redundant error propagation ... Why can printing to the serial port or format onto a string fail? Even if cstyle_format returns Result<usize>, we shouldn't always follow suit.	2022-12-16 18:32:29 +01:00
apio	41b3c8adb2	Convert to_dynamic_unit to OwnedStringView and rename the old variant to to_dynamic_unit_cstr	2022-12-16 18:18:24 +01:00
apio	be22cf6267	Introduce OwnedStringView ... A managed String which uses RAII to free its contents. It's not a proper string though, since it's read-only. So it's a StringView... but an owned one. Can't be copied automatically, must be either moved or copied manually by calling clone() on it.	2022-12-16 18:17:15 +01:00
apio	d759058b80	Introduce std::nothrow ... Let's make sure we explicitly tell new that we don't want exceptions	2022-12-16 18:14:48 +01:00
apio	32c8869973	Option: Simplify release_value ... This avoids copying + we don't need to destroy the item if we move it, since it either gets emptied by moving it or doesn't have anything to destroy.	2022-12-16 18:13:40 +01:00
apio	19a4e2ab58	Result, Option: Make sure everything is properly moved	2022-12-16 18:11:17 +01:00
apio	b9f3d3c349	Remove ENONE ... If you want to return an error without meaning, use Option.	2022-12-08 16:09:33 +01:00
apio	b6173e2b67	LinkedList: Return Option instead of ENONE if no value	2022-12-08 16:09:04 +01:00
apio	406af68a54	Result: Use Option as backend	2022-12-08 16:08:18 +01:00
apio	b58eba63f1	Add a new Option class which behaves like Result, but has no error number, just a value or no value	2022-12-08 16:08:02 +01:00
apio	6cee208e62	Kernel: Enable -Wsign-conversion ... For real this time, turns out me, being dumb, added it to Luna instead of the kernel.	2022-12-08 15:09:32 +01:00
apio	1d5d1daa57	Add scope guards	2022-12-08 14:56:11 +01:00

apio	4fdd1d57f5	Make build-debug.sh also add debug symbols to luna	2022-12-07 16:11:59 +00:00
apio	287c4ab060	Run clang-format	2022-12-07 16:11:59 +00:00
apio	986aa01948	size_t -> usize	2022-12-07 17:06:29 +01:00

apio	ee276a3a35	Add the nodiscard attribute to make and make_array	2022-12-07 11:01:45 +01:00
apio	8598b1e8fc	Replace the _noreturn macro with the C++ native attribute [[noreturn]]	2022-12-06 19:40:35 +01:00
apio	39b310b6b9	Make alignment a template parameter to help the compiler optimize	2022-12-06 19:27:58 +01:00
apio	b5c6ae253d	Make LinkedList a lot better	2022-12-06 18:41:35 +01:00
apio	d8f75f1d3c	LinkedList: Add an append_after() method ... Can be used to append an item after another one instead of at the end of the list. With doubly linked lists, this is extremely easy to achieve (O(1)).	2022-12-06 18:25:08 +01:00
apio	146da13e43	LinkedList: Make sure to explicitly mark the first node's next and last nodes as nullptr	2022-12-06 18:23:19 +01:00
