I need a command that sets the contents of the clipboard to whatever is piped to its input without adding a trailing newline. The following:
C:> *some_command* | clip.exe
adds a newline at the end, while:
C:> *some_command* | powershell.exe Set-Clipboard
does not seem to pass the standard input to Set-Clipboard. Invoking *some_command* via a powershell prompt is not an option. How can I do what I need?
Background: I am using WSL and I want to be able to copy/paste to the system clipboard from vim, tmux, etc. My current workaround uses clip.exe which adds a newline to whatever I yank. For example, in .vimrc I have:
let g:copy = 'clip.exe'
let g:paste = 'powershell.exe Get-Clipboard -Raw'
augroup myYank
autocmd!
autocmd TextYankPost * if v:event.operator == 'y' | call system(g:copy, #") | let g:lastyank='y' | else | let g:lastyank='' | endif
"autocmd TextYankPost * if v:event.operator ==# 'y' | call system(g:copy, #") | endif
"autocmd TextYankPost * call system(g:copy, #")
augroup END
function! Paste(mode)
if g:lastyank == 'y'
let #" = system(g:paste)
endif
return a:mode
endfunction
map <expr> p Paste('p')
map <expr> P Paste('P')
" map Ctrl-c and Ctrl-x as expected
func! GetSelectedText()
normal gv"xy
let result = getreg("x")
return result
endfunc
noremap <C-c> :call system(g:copy, GetSelectedText())<CR>
noremap <C-x> :call system(g:copy, GetSelectedText())<CR>gvx
output your command in a variable then use $var.trim() | Set-Clipboard, but the best would be to generate the proper output first rather than correcting it down the line so maybe the string builder could help you.
$SB = [System.Text.StringBuilder]::New()
Then you can try this depending on the result you want, the string builder will store everything in it's corresponding variable.
$SB.Append($Text)
$SB.AppendLine($Text)
Then finally
$SB | SCB
Sometime also
Out-String -NoNewLine
can help but certain commands will generate blank lines at the end by default so trimming can come in handy sometimes.

I try to use:
string result;
string path = "C:/winccoa.projects/filters/bin/tools/rxrepl.exe";
string cmd = "'opcki' | " + path + " -s 'op' -r 'tata'";
system(cmd, result);
DebugN(result);
But in LogViewer i see nothing, instead ["tatacki"]
Why? What i doing wrong?
In PowerShell that works fine:
PS C:\> 'opcki' | C:/winccoa.projects/filters/bin/tools/rxrepl.exe -s "op" -r "tata"
tatacki
I'm assuming that WinCC's system() function targets cmd.exe, not powershell.exe (which is typical, because historically cmd.exe has been the default shell, and APIs are unlikely to change, so as to maintain backward compatibility).
Therefore, formulate your command for cmd.exe:
string cmd = "echo opcki | " + path + " -s op -r tata";
Not the use of echo to produce output and the omission of single-quoting ('...'), which cmd.exe doesn't recognize.
If embedded quoting were needed, you'd have to use `" inside "..." PowerShell strings (or use '...' PowerShell strings (whose content is taken literally) and embed " chars. as-is).
I'm self-answering this question because I've seen it asked all over the Internet, but with few helpful answers, and definitely no resolutions on Stack Overflow that I can find.
Example Code
Consider this code, which simply writes several lines of shell commands:
^0::
SetKeyDelay, 0, 0
myWindow = ahk_exe Notepad.exe
ControlSend, , set c=".cshrc-andrew.cheong"`n, %myWindow%
ControlSend, , set v=".vimrc-andrew.cheong"`n, %myWindow%
ControlSend, , foreach d ( /userhome/andrew.cheong /home/$USER /data/$USER )`n, %myWindow%
ControlSend, , if ( -e $d/$c ) source $d/$c`n, %myWindow%
ControlSend, , if ( -e $d/$v ) alias vim "vim -N -u $d/$v"`n, %myWindow%
ControlSend, , end`n, %myWindow%
Return
I'm writing the commands to Notepad to show that it is not an issue limited to terminal applications like PuTTy or xterm. It's easy to think so, since these applications sometimes have laggy behavior.
Example Output
Specifically when using SetKeyDelay, 0, 0 for fast "typing," I get all kinds of weird behavior, like:
Double-quotes replaced by single-quotes. Parentheses replaced by 9's and 0's. Dollar signs replaced by 4's.
set c=".cshrc-andrew.cheong'
set v=".vimrc-andrew.cheong"
foreach d ( /userhome/andrew.cheong /home/$USER /data/$USER )
if 9 -e 4d/4c 0 source 4d/4c
if ( -e $d/$v ) alias vim 'vim -n -u 4d/4v'
end
Dashes replaced by underscores. Case changes.
set c='.cshrc-andrew.cheong"
set v='.vimrc-andrew.cheong'
foreach d ( /userhome/andrew.cheong /home/4user /data/$USER )
if 9 -e 4d/$C ) source 4d/$c
if 9 _e $d/$v ) alias vim 'vim -N -u $d/$v"
end
Periods replaced by >'s. More case changes.
set c=".cshrc-andrew.cheong"
set v=">VIMrc-andrew.cheong"
foreach d ( /userhome/andrew.cheong /home/$USER /data/$USER )
if 9 -e $d/$c ) source 4d/$c
if ( -e $d/$V ) alias vim "vim -N -u $d/$v"
end
It's obvious the issue has something to do with the Shift modifier, as if it's being randomly turned on or off.
Why is this happening, and how do we fix it?
Note that there are no problems when using Send and its variants. The issue specifically arises with ControlSend, which is needed to send inputs to specific controls or to an unfocused window.
Solution
Copy this into your script (from user RHCP at AutoHotkey forums):
pSendChars(string, control := "", WinTitle := "", WinText := "", ExcludeTitle := "", ExcludeText := "")
{
for k, char in StrSplit(string)
postmessage, WM_CHAR := 0x102, Asc(char),, %Control%, %WinTitle%, %WinText%, %ExcludeTitle%, %ExcludeText%
return
}
And use it like this:
^0::
myWindow = ahk_exe Notepad.exe
line .= "set c="".cshrc-acheong""`n"
line .= "set v="".vimrc-acheong""`n"
line .= "foreach d ( /userhome/andrew.cheong /home/cama /home/$USER )`n"
line .= " if ( -e $d/$c ) source $d/$c`n"
line .= " if ( -e $d/$v ) alias vim ""vim -N -u $d/$v""`n"
line .= "end`n"
pSendChars(line, "edit1", myWindow)
Return
That's it.
Note that edit1 is Notepad's name for its text control. When using this script for PuTTy, I changed it to a blank string. Use AutoHotkey's WindowSpy program to find out the control you wish to write to.
Why
This has come up a few times before. Just to add to what Lexikos
wrote, the issue is due to the fact that controlSend uses both post
message and sendInput/sendEvent to send keystrokes. This is required
as some programs will not correctly interpret the keystrokes unless
the sent modifier keys are logically down (sent via sendInput/Event).
Modifier keys (unless explicitly stated e.g. {shitft down}) are sent
via sendInput while non-modifers are sent via postMessage. Keys sent
via postmessage are sent directly to the window and so have less delay
than the other keys/messages. Consequently it's possible for keystroke
messages to arrive out of synch resulting in unexpected characters. In
your case the capitalised letters require the shift key to be sent via
sendInput/Event.
In addition to using keyDelays, you can try controlSetText and posting
WM_Char messages. If you're working with a text control i would
recommend using controlSetText.

I'm trying to make a batch file that reads a txt file "ayylmao.txt" and find a specific word "hello" and replaces it with "xello".
The thing is that the "ayylmao.txt" contains specific characters.
Ayylmao.txt looks something like this:
‹‹R‹Ę‹/M‹;Ču‹č˙˙˙‹‹#‰‹‹#CëC;Đu‹čq˙˙˙‹‹#C‹D$‰;7u®‹Ó‹Ćčúţ˙˙„Ŕu3Ŕ‰YZ]_^[ĂŤ# SVWUÄđ‰$‹ô‹‰D$‹
‹‹#;Č‚† ‹Ř‹>_‹ůz;ßrv;Ču!‹B‹A‹B‹)B‹x uV‹čđţ˙˙ëM‹Ř‹>_‹ůz;ßu
‹B‹)Bë3‹Z‰\$‹>‹‹.}+ű‰|$+Č‹‰HŤT$‹čMţ˙˙„Ŕu3 hello Ŕë°ë‹‹ ‰‹;D$…Y˙˙˙3ŔÄ]_^[ĂSVW‹Ú‹đţ }ľ ëĆ˙˙ ć ˙˙‰sjh Vj
You can see the "hello" word in the last line. I want the batch to go to the process and give me a ayylmao1.txt that looks like this:
‹‹R‹Ę‹/M‹;Ču‹č˙˙˙‹‹#‰‹‹#CëC;Đu‹čq˙˙˙‹‹#C‹D$‰;7u®‹Ó‹Ćčúţ˙˙„Ŕu3Ŕ‰YZ]_^[ĂŤ# SVWUÄđ‰$‹ô‹‰D$‹
‹‹#;Č‚† ‹Ř‹>_‹ůz;ßrv;Ču!‹B‹A‹B‹)B‹x uV‹čđţ˙˙ëM‹Ř‹>_‹ůz;ßu
‹B‹)Bë3‹Z‰\$‹>‹‹.}+ű‰|$+Č‹‰HŤT$‹čMţ˙˙„Ŕu3 xello Ŕë°ë‹‹ ‰‹;D$…Y˙˙˙3ŔÄ]_^[ĂSVW‹Ú‹đţ }ľ ëĆ˙˙ ć ˙˙‰sjh Vj
You can see that "hello" is now "xello".
I found this batch file that replaces a word from a text file:
#echo off
REM -- Prepare the Command Processor --
SETLOCAL ENABLEEXTENSIONS
SETLOCAL DISABLEDELAYEDEXPANSION
if "%~1"=="" findstr "^::" "%~f0"&GOTO:EOF
for /f "tokens=1,* delims=]" %%A in ('"type %3|find /n /v """') do (
set "line=%%B"
if defined line (
call set "line=echo.%%line:%~1=%~2%%"
for /f "delims=" %%X in ('"echo."%%line%%""') do %%~X
) ELSE echo.
)
This code works for files that don't have specific characters very good if use it like this:
code.bat "hello" "xello" "ayylmao.txt">"ayylmao1.txt"
This code only types in ayylmao1.txt few special characters but replaces hello. I want all the special characters typed in there.
I made it like this:
chcp 1252
code.bat "hello" "xello" "ayylmao.txt">"ayylmao1.txt"
But it didn't work. It worked just like the first code.
If there is a way in PowerShell to do this I'd be glad to hear it.
What you have there looks like a binary file, not a text file, despite the extension. Batch is no good for editing binary files. In PowerShell it's doable, but you need to resort to working with the data bytes instead of simple text.
This is a basic example that will find the first occurrence of the string "hello" in your file and replace it with "xhello":
$f = 'C:\path\to\ayylmao.txt'
$stext = 'hello'
$rtext = [char[]]'xhello'
$len = $stext.Length
$offset = $len - 1
$data = [IO.File]::ReadAllBytes($f)
# find first occurrence of $stext in byte array
for ($i=0; $i -lt $data.Count - $offset; $i++) {
$slice = $data[$i..($i+$offset)]
if (-join [char[]]$slice -eq $stext) { break }
}
# Once you know the beginning ($i) and length ($len) of the array slice
# containing $stext you can "cut up" $data and concatenate the slices before
# and after $stext to the byte sequence you want to insert ($rtext):
#
# |<-- $stext -->|
# [...]['h','e','l','l','o'][...] <-- $data
# ^ ^ ^ ^
# | | | |
# | $i | $i+$len
# $i-1 $i+$offset (== $i+$len-1)
#
$rdata = $data[0..($i-1)] + [byte[]]$rtext + $data[($i+$len)..($data.Count-1)]
[IO.File]::WriteAllBytes($f, $rdata)
You'll need to adjust this code if you want the replacement to work differently (replace other occurrences as well, replace a different occurrence, …).
But it didn't work. It worked just like the first code. Help ?
This batch code is coming from this site and there is a link to discussion why it doesn't work with special characters.
Yes, the PowerShell replace command can replace the string and keep the special characters. To call it from within your batch script, use the following line
powershell -command "(get-content Ayylmao.txt) -replace 'hello','xello' | set-content Ayylmao.txt"
If you want to enter your parameters from the command line, then the line would be
powershell -command "(get-content %3) -replace '%1','%2' | set-content %4"
And if you want to use variables defined in the batch script, it is the same as you would for any batch script
set file=Ayylmao.txt
set Search_criteria=hello
set Replace_criteria=xello
powershell -command "(get-content %file%) -replace '%Search_criteria%','%Replace_criteria%' | set-content %file%"
I want to call msbuild from the function below and redirect the output to a new buffer.
My problem is that I need to use a variable, for the filename, and therefore cant use '!' (can I?), and when I use exe or system() read complains that I'm not giving it a proper file.
func! myFunction()
let findstr = "findstr /s /m " . '"' . expand("%:t") . '"' . " *.vcxproj"
for project in split(system(findstr), nr2char(10))
echo "Building '" . project . "'"
let msbuild = "c:\\windows\\Microsoft.NET\\Framework\\v4.0.30319\\msbuild.exe" . " " . project . " " . "/t:rebuild /p:configuration=debug"
:tabnew | r system(msbuild) "<--THIS LINE HERE
endfor
endfunc
The :read command takes a file not a vim expression. However it can read in from standard output via :read !{cmd}. Example :%r!ls. Using the :execute command you can build your new command with your variable.
exe '%r!' . msbuild
Or you can use :put along with the expression register if you want to use an expression like system(). (Probably want to follow this with :0d_ to delete the first empty line)
put=system(msbuild)
Now it looks like you are trying to build your project and get a list of errors. I would recommend you look into :make, the 'makeprg' option, and the quickfix list as this is a more vim way of building a project.
For more help see:
:h :r!
:h :exe
:h :pu
:h #=
:h :make
:h 'makeprg'
:h quickfix
This is a function you can use to execute arbitrary shell commands and present their output in a new window ( you can put this in your _vimrc):
let s:lastcmd = ''
function! s:RunShellCommand(cmdline, bang)
" Support for repeating last cmd with bang:
let _ = a:bang != '' ? s:lastcmd : a:cmdline == '' ? '' : join(map(split(a:cmdline), 'expand(v:val)'))
if _ == ''
return
endif
let s:lastcmd = _
let bufnr = bufnr('%')
let winnr = bufwinnr(_)
" You can position the new window whenever you want, I chose below + right:
silent! execute winnr < 0 ? 'belowright new ' . fnameescape(_) : winnr . 'wincmd w'
" I could set buftype=nofile, but then no switching back and forth buffers.
" The results are presented just for viewing, not editing, modify at will:
setlocal buftype=nowrite bufhidden=wipe nobuflisted noswapfile wrap number
setlocal modifiable
silent! :%d
" Useful for debugging, if you encounter issues with fnameescape():
call setline(1, 'You entered: ' . a:cmdline)
call setline(2, 'Expanded to: ' . _)
call append(line('$'), substitute(getline(2), '.', '=', 'g'))
silent execute '$read !' . _
silent! execute 'autocmd BufUnload <buffer> execute bufwinnr(' . bufnr . ') . ''wincmd w'''
" If resizing is unwanted for commands with too much output, remove this line:
silent! execute 'autocmd BufEnter <buffer> execute ''resize '' . line(''$'')'
" You can use <localleader>r to re-execute the last command:
silent! execute 'nnoremap <silent> <buffer> <localleader>r :call <SID>RunShellCommand(''' . _ . ''', '''')<CR>'
execute 'resize ' . line('$')
setlocal nomodifiable
1
endfunction " RunShellCommand(cmdline)
command! -complete=shellcmd -nargs=* -bang Shell call s:RunShellCommand(<q-args>, '<bang>')
Use like:
:Shell gcc -ggdb -o test test.c && ./test
I am trying to configure vim's 'path' and 'suffixesadd' so when I use gf over FILE_NAME, and pwd is /some/dir/, it opens /some/dir/FILE_NAME/File_Name.xml
In vimrc I put:
set suffixesadd=.xml
set path=.,dir/**
But, instead of opening File_Name.xml it opens the directory FILE_NAME
What should I do to configure vim so it looks for files before directories?
PS: Im using gvim in Windows and have NERD plugin active
I don't think this is possible with gf as standard, but you could always do:
" Mapping to make it easier to use - <C-R><C-W> inserts the Word under
" the cursor
nmap gx :call CustomGFOpen("<C-R><C-W>")<CR>
" The function that does the work
function! CustomGFOpen(cursor_word)
" The directory name (e.g. FILE_NAME) is passed as the parameter
let dirname = a:cursor_word
" This is a regular expression substitution to convert
" FILE_NAME to File_Name
let filename = substitute(a:cursor_word, '\(^\|_\)\#<=\([A-Z]\)\([A-Z]\+\)', '\=submatch(2) . tolower(submatch(3))', 'g')
" The extension
let extension = '.xml'
" Join the whole lot together to get FILE_NAME/File_Name.xml
let relative_path = dirname . '/' . filename . extension
" Open that file
exe 'e' relative_path
endfunction
