2023-08-27Make tabwidth option window-localAlexey Yerin1-0/+6
2023-08-24Lua API: access and set all available optionsRandy Palamar1-0/+8
The first point of this commit is to allow all options to be read from lua. This has a number of uses for plugin writers. They are grouped into a couple of tables depending on what they control: `vis.options`: table with global configuration `win.options`: table with window specific configuration The second point is to allow you to set all these options as if they were simply lua variables. Technically this is already possible by using `vis:command("set ...")` but personally I think this interface is cleaner. Note that this already possible for some things like the current mode (eg. vis.mode = vis.modes.VISUAL). Examples: `vis.options.ai = true` `win.options.brk = " !?."` `win.options = { showeof = true, showtabs = true } There are a number of related issues and pull requests: closes #803: Lua API: let plugins read the values of options closes #812: Window layout property supersedes/closes #717: Add ability to access tabwidth from Lua supersedes/closes #1066: expose UI layout and allow it to be set from lua API

2023-05-22check for EOF before unsetting row, col & line cache in view_coord_getJeremy Bobbin1-1/+2
This commit fixes c22b2c2, which introduced a bug when the EOF was in view.
2023-03-19fix bug where visual-line selections after view were considered visibleJeremy Bobbin1-1/+1
prior to this patch, if you had a visual-line selection after the view, and try to move it(& all other selections) up into the buffer, the selection would appear prematurely. https://github.com/martanne/vis/issues/1074

2020-11-20view: make view_selections_dispose_all O(n)Mateusz Okulus1-2/+5
The for loop in selection_free won't run because the next element will always be NULL, because we are freeing from the end. Close #852

2018-05-16vis: make sure zb redraws line at the bottom if possibleMarc André Tanner1-3/+0
Previously it would do nothing if the cursor was already on the last display line. Fix #697
2018-03-12view: use strncat instead of an inline loop to concatenate cell dataMarc André Tanner1-4/+1
2018-03-12view: fix buffer overflow when dealing with combining charactersMarc André Tanner1-2/+5
The `cell.len` attribute refers to the number of bytes of the underlying text which are represented by this cell. The actual NUL terminated data being displayed can have a completely unrelated length. For example a NUL byte has a `cell.len` of 1, but is displayed as `cell.data = "^@"`. Because we currently have a fixed cell capacity of 16 bytes (including the terminating NUL byte) long sequences of combining characters won't be displayed correctly. See also #679
2018-03-11view: properly advance over incomplete unicode sequenceMarc André Tanner1-1/+1
When fetching more text we have to skip the bytes processed by the previous cell, otherwise we end up in an infinite loop.
2018-03-11Reset parsing state after mbrtowc(3) failureMarc André Tanner1-0/+1
The standard says "if an encoding error occurs ... the conversion state is unspecified".
2017-07-14vis-lua: make selection first class primitives in Lua APIMarc André Tanner1-2/+2
2017-07-08view: keep but clear primary selection if instructed to replace allMarc André Tanner1-1/+4
Previously the last selection was kept implicitly to statisfy the invariant that at least one selection needs to exist.
2017-07-05vis: make sure all selections have same anchored stateMarc André Tanner1-1/+3
With the current model the differences between normal and visual mode is that in the latter selections are anchored (meaning one endpoint remains fixed), while in normal mode both endpoints can in principle be updated simultaneously (currently they are always colapsed to a singleton selection, giving the impression of cursors).
2017-07-04vis: implement `gv` by means of new "^ registerMarc André Tanner1-20/+0
This window local register holds the last active selections.
2017-06-27vis: properly set initial window ui optionsMarc André Tanner1-1/+1
This should keep the EOF markers visible when another option is enabled. The whole UI option handling is a bit of a mess. In the longterm more of the drawing code should be moved into Lua.

2017-06-15view: fix view_selections_setMarc André Tanner1-8/+2
The anchor needs to be set after the cursor was positioned, otherwise the cursor placement will immediately destroy the selection for in the non-anchored case.
