This patch removes the per-line cursor cache (`line->cursor`),
reducing implementation complexity. Vertical cursor movement (up/down)
now uniformly places the cursor at the beginning of the line, instead
of trying to restore the previous horizontal position. UX
considerations such as column preservation will be revisited after
core stabilization.
feat: add slice-based accessors for line and editor buffer2025-04-29T12:56:40Zdilluti0nhskimse1@gmail.com2025-04-29T12:53:27Zurn:sha1:5e4cb3121fd3eaf9ed6b6887e8010f6a80ed0f3d
This adds `line_get_slice` and `eb_get_line_slice`, enabling
slice-style (pointer + length) access to line contents without
requiring materialization into a null-terminated string.
- `line_get_slice` returns either the original mmap'd buffer (if the
- line is lazy) or the materialized vector contents (if edited).
- `eb_get_line_slice` wraps `line_get_slice` to provide safe access at
- the editor buffer level. Update `line.h` and `editor.h` headers to
- declare the new functions. Minor documentation improvements to
- clarify "init", "modify", and "get" function categories.
This prepares the codebase for transitioning away from C-string
dependency where possible, improving efficiency and avoiding
unnecessary memory copies.
fix: `line_free` to handle lazy-loaded line appropriately.2025-04-29T07:37:24Zdilluti0nhskimse1@gmail.com2025-04-29T07:37:24Zurn:sha1:c9273c50f42e2df8aa7a3a754e649e55c1d31445
fix `line_cat` to handle lazy-loaded `src` line too
[minor]
add const keyword for line_get_last since it is.
remove: line->last to reduce ambiguity.2025-04-29T06:17:23Zdilluti0nhskimse1@gmail.com2025-04-29T06:14:10Zurn:sha1:fd24eefca89d7e0534ea4ef77aa302bc439da5eb
vec_len is O(1) and it would be fast enough to use it.
introduce line_lazy_init for lazy load (allocate each line when
actually edit it!) per line.
[minor]
remove obsolate line_delete_trailing.
perf: make line from buf directly instead of append each characters2025-04-28T15:40:20Zdilluti0nhskimse1@gmail.com2025-04-28T15:39:20Zurn:sha1:95e17552cd806f29680727f504571a5ffdfb2ff8
implement line_init_from_buf for this.
implement: eb_set_cur_back and eb_set_cur_prev2025-04-26T19:46:10Zdilluti0nhskimse1@gmail.com2025-04-26T19:46:10Zurn:sha1:c699400bf07ee97f3ad05cc59e1c8a6b0fafaa9eimplement: eb_backspace; line_cat still TODO2025-04-26T16:58:25Zdilluti0nhskimse1@gmail.com2025-04-26T16:58:25Zurn:sha1:c7f0a281f58ac12cf339e3de2f9ba44997638d09
line_cat should be implemented; markd it TODO
refactor: move debugs to config.h and handle build gracefully2025-04-26T16:46:27Zdilluti0nhskimse1@gmail.com2025-04-26T16:46:27Zurn:sha1:12443123cb0b6607b4360a96d8bf6880b4a1499f
makefile now handle each object and sources seperately to handle
header change gracefully.
and from now on, #DEBUG should declared inside of config.h
implement: eb_newline2025-04-26T16:34:05Zdilluti0nhskimse1@gmail.com2025-04-26T16:34:05Zurn:sha1:5354050048037031d092343119b6297230b6b7c8
I move around most of because it did not update eb->cur_col correctly.
implement line_split which use vec_split for it
[minor]
implement eb_get_line and eb_line_num
refactor main routine to use them
add DEBUG symbol to makefile and remove lines.o for OBJS
move declaration struct line to line.c from line.h for enhanced OOP
implement: eb_backspace2025-04-24T08:06:58Zdilluti0nhskimse1@gmail.com2025-04-24T08:06:58Zurn:sha1:ba4e3157884a6a2d8a27926eb97e04d0e980105b
