2017-03-05vis: remove word and file name completion from editor coreMarc André Tanner1-77/+0
2017-03-04vis: process command line options when reading from stdinMarc André Tanner1-6/+7
Previously the following had no effect: $ echo foo | vis +"set syntax markdown" - Fix #512
2017-02-25vis: add vis- prefix to pseudo editor keysMarc André Tanner1-163/+163
2017-02-24vis: make help texts optional to produce a smaller binaryMarc André Tanner1-178/+178
$ ./configure --disable-help shrinks the binary by about 20K on a x86_64 system.
2017-02-23vis: remove `gf` and `<C-w>gf` functionalityMarc André Tanner1-36/+0
This can also be implemented using Lua, if desired.
2017-02-23vis: remove number increment/decrement functionalityMarc André Tanner1-59/+0
By now we should have the necessary Lua API to implement this as an extension.
2017-02-22vis: simplify `r` implementation and fix cursor positioningMarc André Tanner1-10/+2
2017-02-15vis: use single function call to print version informationMarc André Tanner1-12/+6
This results in a slightly smaller binary while still avoiding #ifdefs. Close #494
2017-02-15vis: remove motion and text objects related to C functionsMarc André Tanner1-36/+0
These do not really belong into the editor core. If desired they could be implemented in Lua instead.
2017-02-15text-motions: remove unused text_line_lastcharMarc André Tanner1-6/+0
2017-02-14vis: add compile time features to version outputMarc André Tanner1-1/+12
2017-02-10vis: make r handle special keys like <Tab>Marc André Tanner1-8/+4
Unlike vim we do not respect `:set expandtab` here.
2017-02-10vis: make t, T, f and F work for special keysMarc André Tanner1-9/+5
Fix #491
2017-02-08vis: make `ga` and `g8` more robustMarc André Tanner1-1/+5
Fixes CID 141179
2017-02-06Disable keymap for movement_key characterMichael Forney1-1/+6
The character following a movement_key command should not be subject to keymap translation since it is used to find characters in the document.
2017-02-04view: do not let new cursors automatically become primaryMarc André Tanner1-8/+12
We currently have the invariant that the primary cursor is always placed within the visisble viewport. Previously view_cursors_new would automatically make the new cursor primary. This in turn causes the viewport to be adjusted triggering lots of unnecessary redraws. As a result commands creating many new selections might become unbearably slow. Instead the caller has to explicitly make the new cursor primary.
2017-02-02Slight code cleanups, use buffer API where appropriateMarc André Tanner1-3/+2
2017-02-01vis: fix repetition of O when given a countMarc André Tanner1-0/+2
The cursor needs to be adjusted after every insertion, not just the first one. The implementation is currently rather ugly because it clobbers the dot register with pseudo keys.
2017-01-28vis: deindent blank autoindented lines when leaving insert modeMarc André Tanner1-2/+2
Does not work for the current implementation of `O` because the "lookbehind" i.e. second to last processed key is `<Up>` and not `<Enter>`. Fix #383
2017-01-27vis: do not set count when handling 0 motionMarc André Tanner1-1/+2
A count of zero is different than specifying no count. This fixes `0G` which previously moved to the start of the file. Fix #474
2017-01-19vis: make <C-n> in visual mode wrap aroundMarc André Tanner1-6/+13
Strictly speaking we actually not wrap around, but search backwards starting from the first cursor. This is seems more useful when for example renaming a local variable but not starting from its declaration. Close #305
2017-01-19vis: remove <C-o> mapping in insert modeMarc André Tanner1-6/+0
This was never really implemented properly and is not really needed anyway. Close #345
2017-01-18vis: support count for insertion and replacementMarc André Tanner1-2/+10
Fix #372
2016-12-26fix help text for next/prev matchErlend Fagerheim1-2/+2
2016-12-21vis: implement `gh` and `gl` to move by relative byte offsetsMarc André Tanner1-0/+12
2016-12-21vis: implement `go` to move to absolute byte positionMarc André Tanner1-0/+6
2016-12-21vis: implement g8Marc André Tanner1-4/+15
Shows hex values up to the next UTF-8 encoded character.
2016-12-20vis: improve literal insertion via <C-v> in insert modeMarc André Tanner1-21/+6
2016-12-20vis: improve gaMarc André Tanner1-9/+20
2016-12-19vis: introduce vis_register_from utility functionMarc André Tanner1-37/+17
2016-12-09Remove useless variable assignmentMarc André Tanner1-1/+0
Fixes CID 139067.
2016-12-09vis-lua: expose input key event in insert and replace modesMarc André Tanner1-0/+2
2016-12-08vis: rename some internal C function pointersMarc André Tanner1-3/+3
2016-11-28vis: move mark description into core codeMarc André Tanner1-19/+6
2016-11-27vis: cleanup signal handling codeMarc André Tanner1-4/+20
Move all signal handling code out of "library" code into user application.
2016-11-26vis: re-open /dev/tty read-writeableMarc André Tanner1-1/+1
libtermkey's initialization routine tries to write to the underlying file descriptor which fails with EBADF if it is opened read only. This was a problem in the terminal restore code called after a shell command is executed. It should fix the following: $ echo foo | vis - > bar :!/bin/sh exit where before vis would no longer accept any input.
2016-11-25vis: fix I/O redirection bugs, cleanup vis_pipeMarc André Tanner1-1/+1
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.
2016-11-22vis-lua: introduce pre-save hookMarc André Tanner1-0/+1
The first argument is the file object while the second argument denotes the full path to which it will be written. Path might be `nil` if the file is going to be written to stdout. The Lua function is expected to return a boolean value indicating whether the write operation should proceed or be aborted.
2016-11-21vis-lua: rename file_save event to file_save_postMarc André Tanner1-1/+1
Indicating that the event is triggered *after* a successfull write.
2016-11-16sam: use default shell command for <, >, | and ! when applicapleMarc André Tanner1-0/+2
If the shell command is omitted, the last shell command (of any type) is substituted. The most recently used shell command is stored in a new register currently named `!`.
2016-11-15vis: defer UI initialization and overhaul argument parsingMarc André Tanner1-0/+64
Do not initalize curses UI before it is actually needed. Move vis command line argument parsing logic into main.c. This fixes `vis -v` output and exit status. Fix #351
2016-11-09vis: handle cancelation of `r` commandMarc André Tanner1-0/+3
Do not alter the text if <Escape> is pressed instead of a regular replacement character.
2016-11-09vis: improve `r` in normal and replace modeMarc André Tanner1-3/+20
In normal mode `r<key>` was previously implemented as `R<key><Escape>`. However this does not work when the replacement key is `<Enter>` to insert a new line, because in replace mode new lines are not overwritten. The count is now also respected. Also properly support `r` in visual mode where before it was aliased to `c`. Fix #190
2016-11-09vis: unify VIS_OP_{INSERT,REPLACE} implementationMarc André Tanner1-3/+3
They both perform a motion before changing mode.
2016-10-12Only complete up to cursor positionMarc André Tanner1-2/+4
2016-10-11File completion updatesRichard Burke1-4/+4
2016-10-03vis: improve cursor positioning after scrollingMarc André Tanner1-15/+23
Make cursor placement after scrolling (half) pages up/down less arbitrary. Close #390, fix #391
2016-10-02vis: make <C-w> delete word instead of WORDMarc André Tanner1-1/+1
Close #392
2016-09-25vis: disable language map for replacement character of `r` commandMarc André Tanner1-1/+3
The character following the `r` command in normal mode should be treated as regular input given in insert/replace mode, that is no tranformation should be applied. Temporarily disable the language map for this reason. Close #382
2016-09-25vis: move file name and word completion logic to a shell scriptMarc André Tanner1-4/+2
The shell script should be reviewed for quoting issues, currently it allows command injections as in: $ vis-complete "'; rm -f some-file; echo " However it is intended for interactive usage and from within vis it is only ever called with a valid completion prefix. The file name completion logic now supports nested directories. Close #347
