2023-08-27Make tabwidth option window-localAlexey Yerin1-9/+1
2023-08-26support old option names but mark as deprecatedRandy Palamar1-0/+3
This is in response to a comment left on a35e7ea. Backwards compatibility is a good idea for at least a release.
2023-08-24Lua API: access and set all available optionsRandy Palamar1-11/+13
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
2023-07-28view.c: add word wrappingAndrey Proskurin1-0/+9
this is contolled by the wrapcolumn/wc and breakat/brk options related #142: Word wrap and line breaks related #932: Vis for Prose? related #1092: Disabling line wrapping
2023-07-18Add fullscreen param to vis_pipe_collect() and Lua API vis:pipe()Jörg Bakker1-1/+1
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).
2023-07-18fix warning about field width not being an intRandy Palamar1-4/+4
this slipped through in commit 6be370d
2023-07-17Print keybindings containing space correctlyMax Schillinger1-2/+22
Fixes #1060 - :help doesn't display mappings starting with <Space> correctly Co-authored-by: Randy Palamar <palamar@ualberta.ca>
2023-02-12Do tilde expansion only for the tilde character at the beginning of the pattern.Matěj Cepl1-1/+5
2020-11-13vis: use localtime_r(3) instead of localtime(3)Marc André Tanner1-1/+2
This makes it thread safe. While it is unlikely that we use threads in the near future, it is sensible to avoid unnecessary global state.
2020-09-19Add ignorecase optionEvan Gates1-0/+3
Add a global ignorecase boolean option. When set add REG_ICASE to cflags when calling text_regex_compile().
2020-02-10vis: omit error message when vis-menu(1) is cancelledMarc André Tanner1-1/+1
2020-01-28vis: support an optional exit status in :q and :qall commandsMarc André Tanner1-3/+3
This can for example be used to abort git commit messages with :q! 1.
2019-05-23Add layout optionKarl Schultheisz1-0/+13
This introduces a new `set` option for setting the layout to vertical or horizontal, which previously could not be done without creating a new window (via `split` or `vsplit`). Now, `set layout|lay h|v` will control this without creating a new window.
2018-05-30vis: add loadmethod optionMarc André Tanner1-0/+13
Valid values are `read`, `mmap` or `auto`.

2017-06-15vis: rename uses of Cursor to SelectionMarc André Tanner1-21/+21
2017-06-04Add option to hide EOF markerPhilipp Emanuel Weidmann1-0/+2
2017-05-06vis: add doxygen commentsMarc André Tanner1-2/+2
Rename some structures, add typedefs for function pointers, remove unused arguments from vis_run.
2017-05-03text: remove count argument from text_{earlier,later}Marc André Tanner1-4/+7
2017-03-21vis: reject invalid option namesMarc André Tanner1-0/+4
This should fix the ressource leak as found by CID 142510.
2017-03-19Move :set horizon option implementaiton to luaMarc André Tanner1-3/+0
2017-03-19Move :set theme option implementation to luaMarc André Tanner1-6/+0
2017-03-19Move :set syntax option implementation to luaMarc André Tanner1-17/+0
It is no longer possible to change the used syntax by assigning to the `win.syntax = name` field, instead the function win:set_syntax(name)` should be called. The distinction between filetype and syntax lexer to use should probably be clarified/cleaned up at some point.
2017-03-19vis: add infrastructure to dynamically add :set optionsMarc André Tanner1-25/+86
2017-03-14Add experimental raw vt100 UI backendMarc André Tanner1-0/+1
The intention of this is not to slowly reimplement curses but to provide a minimal working terminal UI backend which can also be used for debugging, fuzzing and in environments where curses is not available. Currently no attempt is made to optimize terminal output. The amount of flickering will depend on the smartness of your terminal emulator.
2017-03-02vis: remove :bdelete commandMarc André Tanner1-18/+0
It does not really fit into the style of the rest of the command language. Eventually we should be able to express this kind of thing using a looping construct based on the `X` and `Y` commands.
2017-02-27vis: allow useage of file dialog for :read commandMarc André Tanner1-0/+18
Fix #505
2017-02-24vis: make help texts optional to produce a smaller binaryMarc André Tanner1-12/+20
$ ./configure --disable-help shrinks the binary by about 20K on a x86_64 system.
2017-02-23vis: unify error path of command registration functionsMarc André Tanner1-6/+10
2017-02-08vis: fix cursor positioning after :helpMarc André Tanner1-0/+1
2017-02-05vis: add file argument to vis_pipeMarc André Tanner1-1/+2
2017-02-02vis: support rudimentary help search using :help patternMarc André Tanner1-0/+3
The argument needs to be a valid regular expression. It currently clobbers the last used search term and hence allows repeated searches using `n` and `N` respectively.
2017-01-31vis: add workaround for broken color handling in Terminal.appMarc André Tanner1-0/+3
Terminal.app sets $TERM=xterm-256color and ships a corresponding terminfo description advocating that it is capable of color changes to the 256 color palette when in fact it can not. We introduce a new boolean option "change-256colors" which is true by default but can be used to disable color changes. It is automatically set if Terminal.app is detected using $TERM_PROGRAM. This should fix display artifacts as described in #456.
2017-01-19text-regex: add regex backend based on libtreMarc André Tanner1-0/+1
While memory consumption should be improved, backward searches will still be slow, because they are implemented in terms of repeated forward searches. It needs to be investigated whether the underlying automaton can have its transitions reversed and essentially run backwards, as is the case in sam.
2017-01-15vis: show error messages for failed :map/:unmap commandsMarc André Tanner1-7/+19
Close #458

Fix #447
2016-12-27vis: properly free dynamic key bindingsMarc André Tanner1-2/+2
The handling of :unmap needs to be revisited at some point.
2016-12-17vis: allow boolean :set options to be toggledMarc André Tanner1-13/+29
Boolean options can be toggled by appending `!` to the option name. Close #435
2016-12-16vis: add section about compile time configuration to :help outputMarc André Tanner1-0/+15
2016-12-15vis: more informative error message for :set optionJosh Wainwright1-1/+1
Close #433
2016-12-14vis: add new :set savemethod auto|atomic|inplace optionMarc André Tanner1-0/+15
Specifies how the current file should be saved, `atomic` which uses rename(2) to atomically replace the file, `inplace` which truncates the file and then rewrites it or `auto` which tries the former before falling back to the latter. The rename method fails for symlinks, hardlinks, in case of insufficient directory permissions or when either the file owner, group, POSIX ACL or SELinux labels can not be restored. The option defaults to `auto`.
2016-12-03vis: improve :set option number parsingMarc André Tanner1-5/+21
Only accept numbers in range [0, INT_MAX]. Reject trailing garbage, where before something like `:set cc 50NaN` worked it will now cause an error. Close #418
2016-11-30vis: avoid inconsistent state after file reloading with :eMarc André Tanner1-1/+6
When a file is opened in multiple windows we could end up in an inconsistent state by doing: $ vis some-file :spl :e At this point the two windows were referencing different file objects thus changes in one would not affect the other although they have the same path. Another option would be to reload all windows currently displaying the file being reloaded. We opt for the simpler fix for now.
2016-11-25vis: fix I/O redirection bugs, cleanup vis_pipeMarc André Tanner1-2/+2
The `:!` command did redirect stdout to a pipe which was used by `vis-menu` to return the selected entry. However, this breaks other interactive commands such as `:!/bin/sh` where command output was never displayed. Instead we modified `vis-menu` to re-open /dev/tty for its user interface which makes it work as a regular filter `:|` This patch also obsoletes the interactive flag previously passed to the vis_pipe function. Interactive mode is instead enabled by piping an invalid range.
