2023-08-01Prevent flickering in cursesIan Hixson1-0/+8
Reading from curs_refresh(3X) from curses, calling doupdate() repeatedly will cause 'several bursts of output to the screen'. wnoutrefresh() has the smarts to only copy the changed lines to the copied virtual screen, but doupdate() does not. There have been several bug reports related to flickering but all seems to be inconsistenly reproducible due to different terminal buffering behavior. See #1032, #327 Unfortunately, when I am using a slow display, I still notice flickering, so this commit changes the routines for opening new windows and splitting windows to wait until the last change is finished before calling doupdate().
2023-07-18Add fullscreen param to vis_pipe_collect() and Lua API vis:pipe()Jörg Bakker1-4/+6
This enables restoring the terminal from a fullscreen command like curses based program. Use cases are e.g. a file picker based on some external program like nnn (https://github.com/jarun/nnn).

2021-02-15vis: correctly close pipe connected to stdin of external processMarc André Tanner1-2/+2
Once we have written all data we should properly close the (correct) pipe. Before we wrongly closed the pipe connected to the standard output stream. More generally, we currently do not listen for child process termination, but instead wait until all the connected pipes are closed. This might be problematic in case the external process keeps hold of the standard I/O file descriptors. One particular example of this is wl-copy(1). See #929

2020-11-14vis: fix <C-c> processing after SIGINTMarc André Tanner1-1/+2
There are two main ways how the input queue is managed in vis: - vis_keys_feed(..) appends new input to the queue and immediately starts processing it. Starting from the position before the call i.e. ignoring any previously queued input. This is typically used in key binding handlers where the input queue still contains the mapping leading to the invocation of the handler. In that case new input should be interpreted immediately, before the handler eventually returns and its mapping is consumed. - vis_keys_push(..) with pos=0, appends new input to the end of the queue and starts processing it from the start of the queue, taking the full content into consideration. This is used by the main loop when new input becomes available. This patch switches the handling of <C-c> after a SIGINT from the former to the latter mechanism and fixes mappings using <C-c> in a non-leading position.

2020-05-12vis: cleanup pre-processing of :-commandsMarc André Tanner1-5/+5
Not sure why we need to allocate space for an additional character. This also avoids creating out of bound pointers.

2020-03-17color-column: Don't change fg/bg if not set explicitlyGennadiy Volkov1-1/+6
eg. if your long line is a comment with green fg, and you set your column color bg red while not specifying the fg, then the result is green fg on red bg. Prior to this change the result would be default fg on red bg, thus one char in the long line of green text would look odd/wrong. Of course if you do explicitly set the column color fg to default in your theme then the result will not be what you expect - ideally we need an UNSPECIFIED color type instead of relying on DEFAULT.

2020-02-04vis: make core code more robustMarc André Tanner1-13/+41
The core vis code was originally written under the assumption that there always exists at least one window. However, when being called from the Lua configuration file during start up this is not yet the case. In general, Lua code should always be placed within appropriate event handlers e.g. vis.events.INIT for global configuration. Invoking API functions depending on an active window from top level statements is not supported. Where before the editor simply crashed, these changes turn such code sections into NOPs. Fix #561
2020-01-27vis: make r<Enter> insert a new lineMarc André Tanner1-1/+1
Special case <C-v><Enter> to still insert a carriage return as discussed in #656 and changed in 2cfc9c867bdfd4cc3ae3246f31cf636633fe1a5f. Due to limitations of the current implementation <C-v> is not generic, i.e. combining it as r<C-v><Enter> will not work. Fixes #765

2017-12-09vis: make selections visible when lua support has been disabledMarc André Tanner1-2/+6
When the fore and background colors are the same, swapping them has no effect. Instead use the specified cell attributes. Previously the CELL_ATTR_REVERSE used in the default selection style was ignored. In general the default style definitions for non-Lua builds could probably be improved further. Fix #635
2017-11-04vis: take symbolic keys into account when evaluating key prefixesMarc André Tanner1-6/+32
Previously `ci<` would have no immediate effect because in operator pending mode `i<` was wrongly treated as a powwible prefix of `i<Tab>`. Fix #624
2017-09-15vis: remove ! operatorMarc André Tanner1-11/+1
Use visual mode and :| to filter text through external commands. The mapping was already reused for selection complement.
2017-07-23vis: use strncpy to copy into fixed sized bufferMarc André Tanner1-1/+1
In practice this was never an issue also it is guaranteed that the terminating zero byte is already there. Fixes coverity issue 157023.
2017-07-23vis: only draw selections of currently active windowMarc André Tanner1-2/+3
This should make it easier to see which window is focused.

2017-07-14vis: use distinct mark to save last selectionsMarc André Tanner1-1/+13
This partially reverts f9e2b884c15919757651db8b10c033a344a19e75 further jumps after leaving visual mode should not break `gv`.

2017-07-11Revert "vis: process aliased key sequences individually"Marc André Tanner1-12/+2
This reverts commit 54ca598fcccff8844bfbe494cd3b325b2fea487f. The key handling functions are called too often. This for example causes problems for `r` (replace char) in combination with :langmap.

2017-07-10vis: implement jump list in terms of marksMarc André Tanner1-20/+7
2017-07-08vis: cleanup marks implementationMarc André Tanner1-16/+1
We now use ' to refer to marks. Mark a is set using 'am and restored using 'aM while this is slightly harder to type than ma and 'a it is consistent with register usage for yank/put and allows a default mark to be used which is handy for quick selection manipulation primitives.
2017-07-07vis: use marks instead of registers to store selectionsMarc André Tanner1-11/+9
The key binding remain the same, but the selections are now stored on a per-buffer basis.
2017-07-04vis: implement `gv` by means of new "^ registerMarc André Tanner1-12/+10
This window local register holds the last active selections.
2017-07-04vis: process aliased key sequences individuallyMarc André Tanner1-2/+12
While the complete alias is added to the input queue, the called key bindings should only see the keys they have asked for. Previously a mapping such as: :map! normal gv \"^Sv did not work as expected because the key binding for the register did reject an invalid multi letter register name. Might also influence #581
2017-06-27vis: properly set initial window ui optionsMarc André Tanner1-1/+2
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.
