* perf(extmarks): add metadata for efficient filtering of special decorationsbfredl2024-01-22
| | | | | | | | | | | | | | | | | | This expands on the global "don't pay for what you don't use" rules for these special extmark decorations: - inline virtual text, which needs to be processed in plines.c when we calculate the size of text on screen - virtual lines, which are needed when calculating "filler" lines - signs, with text and/or highlights, both of which needs to be processed for the entire line already at the beginning of a line. This adds a count to each node of the marktree, for how many special marks of each kind can be found in the subtree for this node. This makes it possible to quickly skip over these extra checks, when working in regions of the buffer not containing these kind of marks, instead of before where this could just be skipped if the entire _buffer_ didn't contain such marks.
* refactor(IWYU): fix headersdundargoc2024-01-11
| | | | | | Remove `export` pramgas from defs headers as it causes IWYU to believe that the definitions from the defs headers comes from main header, which is not what we really want.

* refactor(decorations): break up Decoration struct into smaller piecesbfredl2023-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the monolithic Decoration struct. Before this change, each extmark could either represent just a hl_id + priority value as a inline decoration, or it would take a pointer to this monolitic 112 byte struct which has to be allocated. This change separates the decorations into two pieces: DecorSignHighlight for signs, highlights and simple set-flag decorations (like spell, ui-watched), and DecorVirtText for virtual text and lines. The main separation here is whether they are expected to allocate more memory. Currently this is not really true as sign text has to be an allocated string, but the plan is to get rid of this eventually (it can just be an array of two schar_T:s). Further refactors are expected to improve the representation of each decoration kind individually. The goal of this particular PR is to get things started by cutting the Gordian knot which was the monolithic struct Decoration. Now, each extmark can either contain chained indicies/pointers to these kinds of objects, or it can fit a subset of DecorSignHighlight inline. The point of this change is not only to make decorations smaller in memory. In fact, the main motivation is to later allow them to grow _larger_, but on a dynamic, on demand fashion. As a simple example, it would be possible to augment highlights to take a list of multiple `hl_group`:s, which then would trivially map to a chain of multiple DecorSignHighlight entries. One small feature improvement included with this refactor itself, is that the restriction that extmarks cannot be removed inside a decoration provider has been lifted. These are instead safely lifetime extended on a "to free" list until the current iteration of screen drawing is done. NB: flags is a mess. but DecorLevel is useless, this slightly less so

* refactor: replace manual header guards with #pragma oncedundargoc2023-11-12
| | | | | It is less error-prone than manually defining header guards. Pretty much all compilers support it even if it's not part of the C standard.
* feat(extmarks): add 'invalidate' property to extmarksLuuk van Baal2023-11-08
| | | | | | | | Problem: No way to have extmarks automatically removed when the range it is attached to is deleted. Solution: Add new 'invalidate' property that will hide a mark when the entirety of its range is deleted. When "undo_restore" is set to false, delete the mark from the buffer instead.
* feat(extmarks): add "undo_restore" flag to opt out of undo-restoringbfredl2023-11-05
| | | | | | | | | | | | | | | It is a design goal of extmarks that they allow precise tracking of changes across undo/redo, including restore the exact positions after a do/undo or undo/redo cycle. However this behavior is not useful for all usecases. Many plugins won't keep marks around for long after text changes, but uses them more like a cache until some external source (like LSP semantic highlights) has fully updated to changed text and then will explicitly readjust/replace extmarks as needed. Add a "undo_restore" flag which is true by default (matches existing behavior) but can be set to false to opt-out of this behavior. Delete dead u_extmark_set() code.
* build(iwyu): add a few more _defs.h mappings (#25435)zeertzjq2023-09-30

* feat(extmark): support proper multiline rangesbfredl2023-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The removes the previous restriction that nvim_buf_set_extmark() could not be used to highlight arbitrary multi-line regions The problem can be summarized as follows: let's assume an extmark with a hl_group is placed covering the region (5,0) to (50,0) Now, consider what happens if nvim needs to redraw a window covering the lines 20-30. It needs to be able to ask the marktree what extmarks cover this region, even if they don't begin or end here. Therefore the marktree needs to be augmented with the information covers a point, not just what marks begin or end there. To do this, we augment each node with a field "intersect" which is a set the ids of the marks which overlap this node, but only if it is not part of the set of any parent. This ensures the number of nodes that need to be explicitly marked grows only logarithmically with the total number of explicitly nodes (and thus the number of of overlapping marks). Thus we can quickly iterate all marks which overlaps any query position by looking up what leaf node contains that position. Then we only need to consider all "start" marks within that leaf node, and the "intersect" set of that node and all its parents. Now, and the major source of complexity is that the tree restructuring operations (to ensure that each node has T-1 <= size <= 2*T-1) also need to update these sets. If a full inner node is split in two, one of the new parents might start to completely overlap some ranges and its ids will need to be moved from its children's sets to its own set. Similarly, if two undersized nodes gets joined into one, it might no longer completely overlap some ranges, and now the children which do needs to have the have the ids in its set instead. And then there are the pivots! Yes the pivot operations when a child gets moved from one parent to another.
* refactor(map): avoid duplicated khash_t types for valuesbfredl2023-05-17
| | | | | | | | | | | | | | | | | | | | | This reduces the total number of khash_t instantiations from 22 to 8. Make the khash internal functions take the size of values as a runtime parameter. This is abstracted with typesafe Map containers which are still specialized for both key, value type. Introduce `Set(key)` type for when there is no value. Refactor shada.c to use Map/Set instead of khash directly. This requires `map_ref` operation to be more flexible. Return pointers to both key and value, plus an indicator for new_item. As a bonus, `map_key` is now redundant. Instead of Map(cstr_t, FileMarks), use a pointer map as the FileMarks struct is humongous. Make `event_strings` actually work like an intern pool instead of wtf it was doing before.
* refactor: uncrustifydundargoc2023-04-26

* refactor(extmarks): some minor internal API changesbfredl2023-03-16
| | | | | | | | | extranges and a bunch of other improvements are coming for 0.10 This gets in some minor surrounding API changes to avoid rebase conflicts until then. - decorations will be able to be specific to windows - adjust deletion API to fit with extranges
* build: allow IWYU to fix includes for all .c filesdundargoc2022-11-15
| | | | | | | | | | Allow Include What You Use to remove unnecessary includes and only include what is necessary. This helps with reducing compilation times and makes it easier to visualise which dependencies are actually required. Work on https://github.com/neovim/neovim/issues/549, but doesn't close it since this only works fully for .c files and not headers.

* refactor(extmarks): use a more efficient representationBjörn Linse2022-01-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | marktree.c was originally constructed as a "generic" datatype, to make the prototyping of its internal logic as simple as possible and also as the usecases for various kinds of extmarks/decorations was not yet decided. As a consequence of this, various extra indirections and allocations was needed to use marktree to implement extmarks (ns/id pairs) and decorations of different kinds (some which is just a single highlight id, other an allocated list of virtual text/lines) This change removes a lot of indirection, by making Marktree specialized for the usecase. In particular, the namespace id and mark id is stored directly, instead of the 64-bit global id particular to the Marktree struct. This removes the two maps needed to convert between global and per-ns ids. Also, "small" decorations are stored inline, i.e. those who doesn't refer to external heap memory anyway. That is highlights (with priority+flags) are stored inline, while virtual text, which anyway occurs a lot of heap allocations, do not. (previously a hack was used to elide heap allocations for highlights with standard prio+flags) TODO(bfredl): the functionaltest-lua CI version of gcc is having severe issues with uint16_t bitfields, so splitting up compound assignments and redundant casts are needed. Clean this up once we switch to a working compiler version.

* refactor(decorations): mark decorations directly on the marktreeBjörn Linse2021-10-23
| | | | | | | | | | | | | This allows to more quickly skip though regions which has non-decorative marks when redrawing. This might seem like a gratuitous micro-optimization in isolation. But! Soon decorations are gonna crop into other hot inner-loop paths, including the plines.c code for calculating the horizontal and vertical space of text. Then we want to quickly skip over regions with "only" overlaying decorations (which do not affect text size)

* Add new marktree data structure for storing marksBjörn Linse2020-01-14
This is inspired by Atom's "marker index" data structure to efficiently adjust marks to text insertions deletions, but uses a wide B-tree (derived from kbtree) to keep the nesting level down.
