Moving a word forward in z shell - configuration

In zshell how to move forward word, I can set -o vi and use vi format. Is there a way to move forward in zshell by a word

If you're using iTerm2 on OSX, you can use the Natural Text Editing preset under Preferences -> Profile -> Keys.
This supports these key combos (which are very similar to other editors):
alt/option + left = move left one word
alt/option + right = move right one word

The ZLE widget for moving forward by one word is forward-word. Therefore, you may use bindkey to bind this widget to any key you want.
For example,
$> bindkey ^O forward-word
would allow you to move forward by one word when pressing Ctrl-O. Note that ^O is actually a quoted insert of Control followed by O.

Your zsh command prompt works either like emacs or like vi. If it works like vi, put it in command mode (esc) and type w. If it works like emacs, use M-f.
More information available at man zshzle.

Similar to other answers, but for Zsh on iTerm it took me a while to find this:
If you are using Zsh, like Oh My Zsh, in iTerm then go to: Preferences > Profiles > Keys sub-menu
Click + sign
Add your shortcut combo, choose "Send Escape Sequence"
inputs for left and right below.
left:
[1;5D
right:
[1;5C

forward word [Meta]+[f]
backward word [Meta]+[b]
On macOS, [option]+[→] and [option]+[←] work too.

In my zsh terminal it was already set to the below using bindkey
"^[f" forward-word
"^[b" backward-word
I was not sure how to use this, read on Apple Forum's, this is basically
^+[ release it then press f or press esc release it then press f
Similarly for backward,
^+[ release it then press b or press esc release it then press b

if you want to do this in vi itself, no plug-in neccessary
Open the file, type : and insert this line as the command
%s:.*:&
it will make all the substitutions in the file.
sed is the best solution (simple and pretty fast here) if your are sure of the content, if not it need a bit of complexity that is better treated by awk:
awk '
{
# change special char for HTML constraint
Org = URL = HTML = $0
# sample of modification
gsub( / /, "%20", URL)
gsub( /</, "%3C", HTML)
printf( "%s\n", URL, Org, HTML)
}
' YourFile
To complete this easily in Sublime Text, without any plugins added:
Open the base file in Sublime Text
Type Ctrl+Shift+P and in the fuzzy search input type syn html to set the file syntax to HTML.
In the View menu, make sure Word Wrap is toggled off.
Ctrl+A to select all.
Ctrl+Shift+L to break selection into multi-line edit.
Ctrl+C to copy selection into clipboard as multiple lines.
Alt+Shift+W to wrap each line with a tag-- then tap a to convert the default <p> tag into an <a> tag (hit esc to quit out of any context menus that might pop up)
Type a space then href=" -- you should see this being added to every line as they all have cursors. Also you should note that Sublime has automatically closed your quotes for you, so you have href="" with the cursor between the quotes.
ctrl+v -- this is where the magic happens-- your clipboard contains every lines worth of contents, so it will paste each appropriate value into the quotes where the cursor is lying. Then you simply type .html to add the extension.
Use the right arrow to move the cursors outside of the quotes for the href attribute and follow the two previous steps to similarly add an id attribute with the intended ids pasted in.
Voila! You're done.
Multi-line editing is very powerful as you learn how to combine it with other keyboard shortcuts. It has been a huge improvement in my workflow. If you have any questions please feel free to comment and I'll adjust as needed.
With bash one-liner:
while read v; do printf '%s\n' "$v" "$v" "$v"; done < file
(OR)
while read v; do echo "$v"; done < file
Try this -
awk '{print a$1b$1c$1d}' a='' d='' file

To execute it directly in vim:
!sed 's:.*:&:' %
In awk, no regex, no nothing, just print strings around $1s, escaping "s:
$ awk '{print "" $1 ""}' file
home
help
If you happen to have empty lines in there just add /./ before the {:
/./{print ...
list=$(cat basefile.txt)
for val in $list
do
echo ""$val"" >> newfile.html
done
Using bash, you can always make a script or type this into the command line.
This vim replacement pattern handles your base file:
s#^\s*\(.\{-}\)\s*$#\1#
^\s* matches any leading spaces, then
.\{-} captures everything after that, non-greedily — allowing
\s$ to match any trailing spaces.
This avoids giving you stuff like home .
You can also process several base files with vim at once:
vim -c 'bufdo %s#^\s*\(.\{-}\)\s*$#\1# | saveas! %:p:r.html' some.txt more.txt`
bufdo %s#^\s*\(.\{-}\)\s*$#\1# runs the replacement on each buffer loaded into vim,
saveas! %:p:r.html saves each buffer with an html extension, overwriting if necessary,
vim will open and show you the saved more.html, which you can correct as needed, and
you can use :n and :prev to visit some.html.
Something like sed’s probably best for big jobs, but this lets you tweak the conversions in vim right after it’s made them, use :u to undo, etc. Enjoy!

Function to open a file and navigate to a specified line number

I have the output of recursive grep (actually ag) in a buffer, which is of the form filename:linenumber: ... [match] ..., and I want to be able to go to the occurrence (file and line number) currently under the cursor. This told me that I could execute normal-mode movements, so after extracting the file:line portion, I wrote this function:
function OpenFileNewTab(name)
let l:pair=split(a:name, ":")
execute "tabnew" get(l:pair, 0)
execute "normal!" get(l:pair, 1) . "G"
endfunction
It is supposed to open the specified file in a tab and then do <lineno>G, like I am able to do manually, to go to the specified line number. However, the cursor just stays on line 1. What am I doing wrong?
This question, by title alone, would be an exact duplicate, but it talks locating symbols in other files, while I already have the locations at hand.
Edit: My mappings for grep / ag are as follows:
nnoremap <Leader>ag :execute "new \| read !ag --literal -w" "<C-r><C-w>" g:repo \| :set filetype=c<CR>
nnoremap <Leader>gf ^v2t:"zy :execute OpenFileNewTab("<C-r>z")<CR>
To get my grep / ag results, I put the cursor on the word I want to search and enter <leader>ag, then, in the new buffer, I put the cursor on a line and enter <leader>gf - it selects from the start up to the second colon and calls OpenFileNewTab.
Edit 2: I'm on Cygwin, if it is of any importance - I doubt it.
Why don't you set &grepprg to call ag ?
" according to man ag
set grepprg=ag\ --vimgrep\ $*
set grepformat=%f:%l:%c:%m
" And then (not tested)
nnoremap <Leader>ag :grep -w <c-r><c-w><cr>
As others have said in the comments, you are just trying to emulate what the quickfix windows already provides. And, we are lucky vim can call grep, and it has a variation point to let us specify which grep program we wish to use: 'grepprg'.
Use file-line plugin. Pressing Enter on a line in the quicklist will normally open that file; file-line will make any filename of the form file:line:column (and several other formats) to open file and position to line and column.
I only found this (old) thread after I posted the exact same question on vi.stackexchange: https://vi.stackexchange.com/q/39557/44764. To help anyone who comes looking, I post the best answer to my question below as an alternative to the answers already given.
The gF command, like gf, opens the file in a new tab but additionally it also positions the cursor on the line after the colon. (I note the OP defines <leader>gf so maybe vim/neovim didn't auto-define gf or gF at the time this thread was originally created.)

Error with left key in command line

Accessing through putty with putty-256color in terminal type (and UTF-8 Trasl). I press left or right key in the prompt line. It shows this rectangle:
But If I press Ctrl or Shift and Left/Right it moves cursor OK.
When I access through VNC it works fine.

tmux 1.9
Any suggestion?
Thanks.
This is the result of display-panes tmux command to display the panes id.
Originally, it is bound to C-b q but seems like either your right/left keys send this sequence or you have your bindings changed so that that command gets executed on right/left keys.
To check what your keys sequences, use just cat.
To check your tmux key bindings use list-keys command in tmux.

EMACS find-grep command switching windows

I have the following in my .emacs
(defun find-in-workspace(term)
(interactive "sSearchInWorkspace: \n")
(grep-find (concat "grep -rnH --include=\*.{c,cpp,h} --include=-e '" term "' /home/workspaces/*")))
which is just a wrapper around grep-find so that it can search all the files in my workspace.
My problem is with the grep buffer. I would like to keep my cursor in the grep buffer's window when I select items from it so that I can quickly browse through the code, but selecting a line will automatically moves my cursor to the other window, which adds up in keystrokes when I have a list of over 5 items. Is there anyway I can build this functionality into this function, or change a setting for grep-find? I've been searching but haven't found a solution.
See the functions next-error and previous-error. They leave the grep buffer, but they work from anywhere, so, for example, if you bind next-error to a convenient a key then you can keep pressing it and it will iterate over the grep buffer.
There might be some options of grep behavior, that you might find if you dig in the lisp/progmodes/grep.el from the source, but I really think it might be better and easier to have a look of GrepPlus library which bring many enhancement of emacs grep.
Otherwise you could also use occur and see how you could customize it. In occur, when you are in the match buffer, you can it C-o instead of Ret, which will show in the other buffer the match you selected, keeping your cursor in the match buffer. Difference with grep, is that it only works with opened buffer. I'm rather sure grep+ might have the equivalent. You should have a look
There are two functions for doing exactly what you want: previous-error-no-select and next-error-no-select.
Also, you may find useful next-error-follow-minor-mode.

Set up "toggle comment" command in slickedit? Add more than one hotkey to a command in slickedit?

Is there a way to do either of these two things?
Add hotkey to "toggle comment". By
default slickedit seems to have 2
separate commands, comment and
erase-comment. I wish to have a single
hotkey to handle both (similar to how
eclipse/netbeans handles it).
█
Add 2 separate hotkeys to do the same
command.
In SE16 (probably also in previous versions, I didn't check) you'll find a command toggle-comment (look in source file box.e). You may bind that to a key.
And the second one is simple: Go to Tools -> Options, select category "Keyboard and Mouse", sub "Key Bindings". Search the command/key you need, and press the button "Add..." to add another key binding.
