* UI/TUI: improvements and cleanups for scrolling and clearingBjörn Linse2018-11-11
| | | | | | | | | | | | - TUI: _never_ rely on BCE for implicit clearing, only explicit commands. - TUI: use unibi_erase_chars when possible. - TUI: use end-exclusive ranges for invalid and cleared areas - screen: scrolling leaves scrolled in aree undefined. This is a conservative change, a client assuming the old semantics will still behave correctly. - screen: factor out vsep handling from line drawing. This is needed anyway for the multigrid refactor. - screen: simplifications of win_do_lines
* ui: disable clearing almost everywhereBjörn Linse2018-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid clearing the screen in most situations. NOT_VALID should be equivalent to CLEAR unless some external force messed up the terminal, for these situations <c-l> and :mode will still clear the screen. Also eliminate some obsolete code in screen.c, that dealt with that in vim drawing window 1 can mess up window 2, but this never happens in nvim. But what about slow terminals? There is two common meanings in which a terminal is said to be "slow": Most commonly (and in the sense of vim:s nottyfast) it means low bandwidth for sending bytes from nvim to the terminal. If the screen is very similar before and after the update_screen(CLEAR) this change should reduce bandwidth. If the screen is quite different, but there is no new regions of contiguous whitespace, clearing doesn't reduce bandwidth significantly. If the new screen contains a lot of whitespace, it will depend of if vsplits are used or not: as long as there is no vsplits, ce is used to cheaply clear the rest of the line, so full-screen clear is not needed to reduce bandwith. However a left vsplit currently needs to be padded with whitespace all the way to the separator. It is possible ec (clear N chars) can be used to reduce bandwidth here if this is a problem. (All of this assumes that one doesn't set Normal guibg=... on a non-BCE terminal, if you do you are doomed regardless of this change). Slow can also mean that drawing pixels on the screen is slow. E-ink screens is a recent example. Avoiding clearing and redrawing the unchanged part of the screen will always improve performance in these cases.
* vim-patch:8.1.0448: cursorline not removed when using 'cursorbind'Justin M. Keyes2018-10-16
| | | | | | Problem: Cursorline not removed when using 'cursorbind'. (Justin Keyes) Solution: Store the last cursor line per window. (closes vim/vim#3488) https://github.com/vim/vim/commit/4a5abbd6138240d109278fe1f0b45489d22f712d
* vim-patch:8.1.0435: cursorline highlight not removed in some situation (#9059)Justin M. Keyes2018-09-27
| | | | | | | Problem: Cursorline highlight not removed in some situation. (Vitaly Yashin) Solution: Reset last_cursorline when resetting 'cursorline'. (Christian Brabandt, closes vim/vim#3481) https://github.com/vim/vim/commit/8c63e0ec314ba07d54b881dc629fe19e6eda1fb8

| | | | | | Problem: Moving the cursor is slow when 'relativenumber' is set. Solution: Only redraw the number column, not all lines. https://github.com/vim/vim/commit/bd9a53c06c8869ad811cb3dd01a309c9be7d7a63
* vim-patch:8.1.0373: screen updating still slow when 'cursorline' is setJustin M. Keyes2018-09-13
| | | | | | Problem: Screen updating still slow when 'cursorline' is set. Solution: Fix setting last_cursorline. https://github.com/vim/vim/commit/1b7fefcbce5dd2fd337e217d4857b941da3f8bed
* vim-patch:8.1.0372: screen updating slow when 'cursorline' is set (#8986)Justin M. Keyes2018-09-12
| | | | | Problem: Screen updating slow when 'cursorline' is set. Solution: Only redraw the old and new cursor line, not all lines. https://github.com/vim/vim/commit/90a997987dbbe43af3c15118a35f658f0f037d1d

* vim-patch:8.1.0174: after paging up and down fold line is wrongJan Edmund Lazo2018-09-10
| | | | | | | Problem: After paging up and down fold line is wrong. Solution: Correct the computation of w_topline and w_botline. (Hirohito Higashi) https://github.com/vim/vim/commit/907dad72ef9d29422352fb74ba156e7085a3fc71
* vim-patch:8.0.0515: ml_get errors in silent Ex mode (#8452)KunMing Xie2018-05-30
| | | | | | Problem: ml_get errors in silent Ex mode. (Dominique Pelle) Solution: Clear valid flags when setting the cursor. Set the topline when not in full screen mode. https://github.com/vim/vim/commit/d5d37537d1fa46fd468bd378af2006dd09840f38
* screen.c: define column width by function (#5802)Matthieu Coudron2018-03-18
| | | | | | | This does not change the behavior but centralizes column size for future use (like dynamic signcolumn width depending on the maximum number of signs on a line). The returned value is limited by the size of the `extra` tab in win_line (currently allows for 18 ASCII characters).
* vim-patch:8.0.0448: some macros are lower case (#7936)KunMing Xie2018-01-30
| | | | | | | Problem: Some macros are in lower case, which can be confusing. Solution: Make a few lower case macros upper case. https://github.com/vim/vim/commit/b5aedf3e228d35821591da9ae8501b61cf2e264c ref #6297

| | | | | | | | | | | | | | | | | | | | | vim-patch:8.0.0181 Problem: When 'cursorbind' and 'cursorcolumn' are both on, the column highlignt in non-current windows is wrong. Solution: Add validate_cursor(). (Masanori Misono, closes vim/vim#1372) https://github.com/vim/vim/commit/519d7785f4437762c07b2e04217f83a069a8c663 vim-patch:8.0.0182 Problem: When 'cursorbind' and 'cursorline' are set, but 'cursorcolumn' is not, then the cursor line highlighting is not updated. (Hirohito Higashi) Solution: Call redraw_later() with NOT_VALID. https://github.com/vim/vim/commit/e47683a0913f102b6ae08c8848d5aa675d99b188 vim-patch:8.0.0188 Problem: Using NOT_VALID for redraw_later() to update the cursor line/column highlighting is not efficient. Solution: Call validate_cursor() when 'cul' or 'cuc' is set. https://github.com/vim/vim/commit/9506cad7a1a6e52a613f356de969cbd980815777

* src/*: Remove `VIM - Vi improved ...` headerMichael Reed2015-11-27
| | | | | | | | | | | | | | | | | | | Regarding the individual items in the header: `Vim - Vi improved by Bram Moolenar` Bram Moolenar is already mentioned throughout the documentation, as well as the intro screen. `:help uganda` It's already shown to all users who don't use `shortmess+=I` upon starting nvim, and is already placed prominently in help.txt, i.e., `:help` run with no arguments. `:help credits` Already mentioned near the top of help.txt. `README.md` Already mentioned in develop.txt.

* "halfway a line" is a very confusing phraseJack Danger Canty2015-01-22
| | | | | | | | | If you Google for this phrase found in the Vim documentation you'll find almost exclusively hits from the Vim documentation. I think changing "halfway a line" to "halfway through a line" makes more sense. There seems to be an pervasive odd use of the word 'halfway' in the original docs which I'm updating everywhere.

* Add automatic generation of headersZyX2014-06-02
| | | | | | | | | | | | | | | | | - The 'stripdecls.py' script replaces declarations in all headers by includes to generated headers. `ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'` was used for this. - Add and integrate gendeclarations.lua into the build system to generate the required includes. - Add -Wno-unused-function - Made a bunch of old-style definitions ANSI This adds a requirement: all type and structure definitions must be present before INCLUDE_GENERATED_DECLARATIONS-protected include. Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is the only exception.
