2016-05-18vis: add an interactive mode to vis_pipe{,_collect}(...)Marc André Tanner1-2/+2
Previously the interactive mode was implicitly enabled by passing an invalid range. However for some use cases (e.g. completion) we need to be able to pipe a given text range to an external process without also redirecting stderr (which is used to draw the slmenu interface on top of vis).
2016-05-14vis: allow :commands with a hyphen in the nameMarc André Tanner1-1/+1
This fixes the argument parsing for the :{un,}map-window commands.
2016-05-05sam: avoid taking snapshots within the filter command implementationMarc André Tanner1-18/+1
This has the effect that multiple filter commands can be undone together.
2016-04-29vis: do not crash when processing :-commands and no window is activeMarc André Tanner1-3/+29
This is needed to make the vis.event.start Lua callback useful, setting global options should be possible even if no windows exist yet. The :set command options should probably be cleaned up further, some of them apply only to the currently active window while others have a global effect.
2016-04-21vis: add infrastructure to register custom :-commandsMarc André Tanner1-1/+5
2016-04-21vis: do not lazy allocate :-commandsMarc André Tanner1-9/+11
The built in commands should always be available.
2016-04-20vis: handle termination from within win_open event gracefullyMarc André Tanner1-9/+10
2016-04-17sam: except for visual mode, apply :w to whole fileMarc André Tanner1-16/+57
Also in visual mode, warn if :w is not forced by ! because the file will be reduced to the active selection.
2016-04-13sam: improve ^ matching start of lineMarc André Tanner1-4/+10
There are some nasty differences between the meaning of ^ in Plan 9's regexp library and POSIX when using REG_NEWLINE. The former only matches at the beginning of a line wheras the latter matches the zero-length string immediately after a newline character \n. As a result this also matches after the very last newline at the end of the file. This is undesired behavior for a command like :x/^/c/#/ Hence we try to filter out this last match. Close #264
2016-04-13Use view_cursors_new_force where appropriateMarc André Tanner1-14/+2
Close #263
2016-04-11sam.c: fix some typos in commentSteven Noonan1-2/+2
Signed-off-by: Steven Noonan <steven@uplinklabs.net>
2016-04-08sam: change default address of < and | commandsMarc André Tanner1-11/+16
If no address is provided these commands no longer apply to the whole line, but instead will insert the output of the external program at the current cursor location.
2016-04-06sam: include limits.h for PATH_MAXMarc André Tanner1-0/+1
Close #220
2016-04-05vis: remove left over from :sam commandMarc André Tanner1-4/+4
2016-04-05vis: fix coverity scan warningsMarc André Tanner1-1/+1
2016-04-05sam: cosmetic changesMarc André Tanner1-2/+2
2016-04-05sam: improve group handling, do not loop infinitelyMarc André Tanner1-2/+4
2016-04-05sam: stop executing once a command failsMarc André Tanner1-2/+2
2016-04-05sam: some commands should only be executed once not for every selectionMarc André Tanner1-21/+24
This should fix a segfault when using :q while multiple selections are active.
2016-04-04sam: fix x command with default patternMarc André Tanner1-8/+15
The end range should still be respected, previously it would continue looping for all lines until the end of file.
2016-04-04sam: y and Y commands require a regexp patternMarc André Tanner1-2/+4
2016-04-04sam: use better default addresses for <, >, | and r commandsMarc André Tanner1-25/+21
2016-04-04sam: fix special handling of single line numbersMarc André Tanner1-6/+17
If only line numbers are given (either in absolute or relative form) we treat it as motion instead of a range specifier. That is :nn moves to line nn, but does not select it. This should however not affect other range specifiers such as :n,m
2016-04-04sam: fixup bf52c0cb95b76b4ae17f138c9d98552c38185f46Marc André Tanner1-1/+1
For commands like :q the view might already have been freed
2016-04-04sam: add missing include for strncasecmp(3)David B. Lamkins1-0/+1
2016-04-03sam: focus first cursor after a x, y, g, v commandMarc André Tanner1-0/+4
2016-04-03sam: implement cd (change directory) commandMarc André Tanner1-0/+10
2016-04-03sam: support % as address denoting the whole fileMarc André Tanner1-3/+4
2016-04-03sam: implement ! commandMarc André Tanner1-0/+7
2016-04-03vis: change vis_pipe API and cleanup related codeMarc André Tanner1-25/+20
2016-04-03sam: unify vi(m) and sam command lineMarc André Tanner1-85/+153
The following vi commands have been dropped: - saveas - xit - ! The following commands are only recognized in their short form: - e (edit) - q (quit) - s (substitute) - w (write) - r (read)
2016-04-03sam: restructure code to avoid useless gotoMarc André Tanner1-15/+6
2016-04-03sam: implement s (subtitute) command in terms of sed(1)Marc André Tanner1-3/+13
Eventually this should be rewritten as an internal command.
2016-04-03sam: cleanup command argv passing/handlingMarc André Tanner1-60/+52
2016-04-03sam: simplify and fix groupingMarc André Tanner1-37/+26
The following should now work: :sam x/^static/ .,+/^\}/ { i/<</ a/>>/ }
2016-04-03sam: attempt to make x/y commands more robustMarc André Tanner1-4/+8
These commands can be followed by an address which changes the range to which the sub command applies. The looping construct should then continue at the position of the last change within the original range. A previously problemeatic example: :sam x/^static/ .,+/^\}/ c/replaced
2016-04-03sam: implement > commandMarc André Tanner1-6/+24
2016-04-03sam: implement r (read) command in terms of < catMarc André Tanner1-1/+13
It replaces current range with the file content. However in the common case the range is actually defaults to the whole file which is probably not what is expected.
2016-04-03sam: implement < command in terms of | with an empty rangeMarc André Tanner1-1/+13
2016-04-03sam: implement | (filter) commandMarc André Tanner1-4/+81
2016-04-03sam: implement w (write) commandMarc André Tanner1-4/+47
2016-04-03sam: add infrastructure to support multi letter commandsMarc André Tanner1-48/+52
2016-04-03sam: fix escape handling in regex parsingMarc André Tanner1-0/+4
2016-04-03sam: more flexible parsingMarc André Tanner1-22/+124
Add infrastructure to handle commands which take file names, shell commands or general white space delimited parameters as arguments.
2016-04-03sam: treat single line numbers as motions not rangesMarc André Tanner1-2/+9
That is something like :sam +5 or :sam 10 will move to the start of the selected line instead of selecting the whole line. TODO: due to the current implementation it will also affect :sam x/pattern/-10+10
2016-04-03sam: remove old cursor/selection before executing commandMarc André Tanner1-1/+12
Because duplicated cursors are no longer allowed we have to remove the old cursors before, not after executing the sam command. Otherwise commands like g/foo/ which re-create the same selection fail.
2016-04-03sam: fix default regexp handling i.e. ':sam x'Marc André Tanner1-1/+1
2016-04-03sam: adapt to changes in multiple cursors APIMarc André Tanner1-10/+7
2016-04-03sam: fix negative relative line number placementMarc André Tanner1-7/+11
This should fix -0+,+0-
2016-04-03sam: change print command behavior when given an empty rangeMarc André Tanner1-6/+23
Only create a selection (and switch to visual mode) if at least one print command was given a non-empty range. Also reject invalid ranges. This allows cursor movements with thinks like #10
