<backspace> not bound properly in haskell-mode
by Keshav Kini 25 Jul '14

25 Jul '14

When I have a .hs file open in a buffer (i.e. with haskell-mode activated), it seems that typing <backspace> in <N> state actually deletes characters. Investigating a bit, I see that in other modes - such as message-mode, in which I'm typing this email - doing describe-key on <backspace> yields the following: DEL (translated from <backspace>) runs the command evil-backward-char, which is an interactive compiled Lisp function in `evil-commands.el'. In haskell-mode, however, I get: <backspace> runs the command haskell-indentation-delete-backward-char, which is an interactive compiled Lisp function in `haskell-indentation.el'. The difference I notice is that in the first, we have "DEL (translated from <backspace>)", but in the second, just "<backspace>". From this I gather that evil-mode probably traps the key DEL, but not the key <backspace>. Should evil-mode perhaps trap <backspace> directly as well as DEL? Or is this a bug in haskell-mode, i.e. should haskell-mode be trapping DEL instead of <backspace>? -Keshav

Last character in visual selection remains unhighlighted
by Leo Alekseyev 28 May '14

28 May '14

Hi all, It seems that a lot of the time, visual selection for me is visually off by one character. For example, consider the following line, with the cursor at BOL. (123) If I issue commands like "vf)", "v%", I end with the closing paren under the cursor, but the visual mark will NOT include the closing paren, and will only include the first 3 characters, "(123". Now, it is important to note that if I then try to yank the selection, the yanked region is exactly what it should be, i.e. it will include the closing paren. As such, this defect for me is purely cosmetic, but a little annoying. Is this a known issue? Is it possible there is some misconfiguration on my part? Thanks, --Leo

New evil plugin: evil-args
by Connor Smith 22 Mar '14

22 Mar '14

Hi all, I wanted to notify this board about a new plugin I wrote for evil called evil-args. It provides motions and text objects for delimited arguments. For example, `cia` changes: function(arg1, arg2, ar|g3.f()) to function(arg1, arg2, |) You can find more examples and the source at https://github.com/wcsmith/evil-args. Any feedback on code or issue reports would be welcome. --Connor

Visual selection search/replace
by Leo Alekseyev 05 Mar '14

05 Mar '14

I am slowly attempting to start using vim commands in place of Emacs ones; recently I've been trying to use :s/foo/bar/g in place of query-replace. Looking at the vim docs, it seems that \%V "atom" in a :s command can be used to obtain the same effect as emacs' query-replace-region (see http://vim.wikia.com/wiki/Search_and_replace_in_a_visual_selection) but this doesn't seem to work in Evil. Is this a known bug? If so, is there an official list of Vim/Evil differences that I can refer to instead of spamming this list? :) --Leo
