I know how to comment out multiple lines in VIM, but what if I wanted to add comments in the end of each line?
For example:
function dir.ls(path)
local i,files = 0,{}
local pfile = io.popen('ls "'..path..'"')
for fname in pfile:lines() do
i = i + 1
fpath = path..fname
files[i] = fpath
end
pfile:close()
return files
end
Now with added comments:
function dir.ls(path)
local i,files = 0,{}
local pfile = io.popen('ls "'..path..'"')
for fname in pfile:lines() do
i = i + 1
fpath = path..fname -- your comment goes here
files[i] = fpath -- your comment goes here
end
pfile:close() -- your comment goes here
return files
end
Append your comment to the first line:
A -- your comment goes here<Esc>
Move the cursor to the next line you want to add a comment to.
Repeat the last edit:
.
And so on…
In your example:
A -- your comment goes here<Esc>
j.
jj.
Another method, but in a single step:
:,+3v/end/norm A -- your comment goes here<CR>
That command is easier to understand if it is explained from right to left:
The :normal command allows you to execute a sequence of normal mode commands from command-line mode. Here, we use it to append the comment to the given line, just like in the first step of the multi-step method.
v/pattern/command is a companion to the :global command. It means "run the given command on every line in the given range that doesn't match pattern". Here, we run our :normal command on every line in the given range that doesn't contain end.
,+3 is the range of lines on which we want to run the :v command. It is a shortened version of .,+3 which means "the current line and the next three lines".

I am working in vim. I have a piece text that looks like :
one = 24
two = 52
three = 56
four = 74
Is there a way to use visual select to yank and paste up to the equal to sign in each line ? I want an operation that leaves me with the following result :
one = 24
two = 52
three = 56
four = 74
one =
two =
three =
four =
My current solution is to copy the whole thing, then jump to the one = 24 line in what I copied and then record this macro : 0f=ld$j to #w and then repeat it three times with 3#w. Is there a way to do this using visual select and yank and paste ?
I tend to use :substitute for these things
" First I yank and paste, in normal mode
yapP
" Then I transform
gv " to reselect, while in normal mode
:s/=.*/=/ " that will actual display :'<,'>s/.....
The actual reselection part may need a little work depending on where the cleared snippet shall appear. May be something like yapo<esc>p:'[,']s/=.*/=/ + enter
You can visually select the lines to apply normal commands to them with :norm.
Thus, you could do:
ggVG:norm f=ld$
How about
:global /=/ copy $ | substitute /=\zs.*//
We use global to select the original lines, then copy them to the end $ and remove the parts after = with substitute.
You could use a mapping like this
vnoremap ,s y:let #"=system('sed -nE "s/=.*/=/p"',#")<cr>
When selecting now some lines in in visual mode, type ,s. This will put the desired modification into the " register and you can paste them now using p wherever you want.
Some of my text are in different lines inside same cell. I want them in single line. How do I bring them in single line ?
Example:
first cell contains:
Hi Ram, I want to go to movie today.
Are you willing to join?
If yes, let me know early.
Example:
Expected output:
Hi Ram, I want to go to movie today.Are you willing to join?If yes, let me know early.
New line in a cell A1 caused by alt+Enter for example, may be removed using a formula such as:
=SUBSTITUTE(A1,CHAR(10)," ")
Where A1 is the cell containing the text to be changed. You can enter the formula above in a different cell of course.
The parameter " " indicates 1 space to replace the line break. You could use any other character.
Another type of line break is CHAR(13). You can remove CHAR(13) using the same function again:
=SUBSTITUTE(SUBSTITUTE(A1, CHAR(13)," "), CHAR(10), " ")
In case you had some spaces already before the new-line character, you need to wrap the above formula in a TRIM function like so:
=TRIM(SUBSTITUTE(A1,CHAR(10)," "))
OR
=TRIM(SUBSTITUTE(SUBSTITUTE(A1,CHAR(13)," "),CHAR(10)," "))
Always make a copy of your file before you apply formulas that could change the data.
Note-1:
char(13) is officially called "carriage return" and char(10) is called "line feed".
CHAR(10) returns a line break on Windows, and CHAR(13) returns a line break on the Mac. This answer is for Windows. You can't visually see it but you can see its effect.
Note-2:
As #kojow7 answered, a text wrap can cause the text to appear on more than 1 line depending on the cell width and the text length. This answer does not resolve this case.
Related discussion can be found here: Remove line breaks from cell.
Two things you may need to fix here: 1) Line breaks and 2) Text Wrapping
To fix line breaks:
Select the cells that need to be changed
Press CTRL+H to open Search and Replace
In the Find box type CTRL+J to insert the line break character (it may look like nothing was inserted in the field, but it does insert a line break)
Decide whether to replace the line breaks with a space or with nothing
Press Replace All
To turn off text wrapping:
Select the cells that need to be changed
Go to the Home Tab
In the Alignment Group check to see if the Wrap Text button is clicked.
If it is, click on it again to deselect it.
Depending on your situation, you may need to fix either one or both of these.
Depending on your document it might contain linefeeds or carriage returns or BOTH.
Alexander Frolov (https://www.ablebits.com/office-addins-blog/2013/12/03/remove-carriage-returns-excel/) has written a very good blog post about different technics of finding and removing linebreaks in an Excel file. We will use the “macro way” of doing that – as it is the one that works either on Windows AND Mac. The search replace method offered here too will not work on Mac but on windows.
Add the below Macro to your document (slighlty modified from the original)
Change the value of “ReplaceWith” from ” ” (space) to anything you like a linebreak to be replaced with.
E.g. ReplaceWith = “-” will result in “Line1-Line2-Line3”
Run the Macro (Extras > Macro) while all cells are selected.
Sub RemoveCarriageReturns()
ReplaceWith = " "
LinefeedChar = Chr(10)
Dim recordRange As Range
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
For Each recordRange In ActiveSheet.UsedRange
If 0 < InStr(recordRange, LinefeedChar) Then
recordRange = Replace(recordRange, LinefeedChar, ReplaceWith)
End If
Next
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
End Sub
If your separate lines are not gone by now please change "LinefeedChar" from "Chr(10)" to "Chr(13)" and run it again
Spell Check is a default application in Linux. With the help of that application, can we check the spelling of a text field while users enter data?
Some (or many?) Linux distributions contain a command line utility that is called spell. If you run this with words as parameters, you need to press return a second time, but if you use a file as a paramater, you don't need to press return again. This means that a solution could be:
write the text of a field to a file
run the command line utility from LiveCode's shell function with the file as parameter
parse the result returned by the shell function
Before you try this, open your terminal on Linux and type spell. Press enter to see if the command is recognised. If yes, then the script below should work.
This script writes the text of a field to a file, does a spell check on the file and returns the incorrect words to LiveCode. I haven't tested the script and you may have to tweak it a little.
function spellCheck theText
// works on Linux only
if the platform is "Linux" then
// remove everything that isn't a word
put replaceText(theText,"[^\w]","") into myWords
// write clean data to a temporary file
put the tempName into myTempFile
put myWords into url ("file:" & myTempFile)
// call spell with shell
put "spell" && myTempFile into myShell
// only return the incorrect words
put line 2 to -1 of shell(myShell) into myCorrections
// return the incorrect words to calling handler
return myCorrections
else
// this isn't Linux
return "error"
end if
end spellCheck
//theField is the short name of a field
on checkField theField
// call above function
put spellCheck(the text of fld theField) into myWords
// myWords should now contain the incorrect words
if myWords is not "error" then
lock screen
// parse incorrect words and mark them in the field
repeat with x = 1 to number of words of field theField
if myWord is among the lines of myWords then
// an incorrect word has been found and is marked red
set the textColor of word x of fld theField to red
end if
end repeat
unlock screen
end if
end checkField
Usage: checkField shortNameOfTheField
I'm working with AutoIt, and I was wondering in there is a method I can use to append a string of text to the end of a line inside a text file. I've been browsing all over autoit forums and there are lots of answers that are really close, but I have not found a solution that has actually worked for me.
The function:
FileWriteLine($LOG, "FText")
just adds a whole new line at the bottom, while the function:
_FileWriteToLine($LOG, 1, "FText", 0)
adds the letters "FText" to the beginning of the first line in the log file.
Is there any way I can add this text to the end of the first line, instead of the beginning?
I have never come up with this problem but just thinking of it, how about reading the whole line, storing it in a variable, add the extra test you want in the end of the line and then write the new line as it is modified replacing the old line???
You can use the FileWrite function: FileWrite documentation
You can create your own file writing function to include the opening, writing, and closing of the file like this:
Func WriteToLog($FileName, $Value)
$FileHandle = FileOpen($FileName, 1) ; 1 = append mode
If $FileHandle <> -1 Then
FileWrite($FileHandle, $Value)
EndIf
FileClose($FileHandle)
EndFunc
Then using your example and assuming $LOG is the file name for your log file, you can simply call your function whenever you need to log something:
WriteToLog($LOG, "FText")
I am using ruby on rails but that does not matter much for this question. Let's say that i have a statement like this
error = 'this is an error message'
I have noticed that I end up doing this a lot
error = 'this is an error message'
puts "error = #{error.inspect}"
I am sure a macro can be written which would take the work on the left hand side of left most = and then create another line along with template shown above.
I am using mvim on mac. Any pointer in terms of where I should start to look for developing what I want.
Try snipmate:
http://www.vim.org/scripts/script.php?script_id=2540
I recorded a simple macro that does your sample. To record a macro type q followed by what register you want the macro to be put in (convention calls for qq). To play the macro type # then the macro register. You can view this at :help recording
To write the macro, use the following commands (and here is how is should look in the register)
^yEoputs "error = #{^Op.inspect}"^[
^ moves to the first non whitespace character of the line
yE yanks to the end of the space separated word.
o Puts you in insert mode on the next line
puts "error = #{ is the text that you type out
^O is ctrl+O (capital letter o) - this allows the next, and only the next command to be run in command mode, which is...
p Puts the yanked word, after this command is run you're still in insert mode
.inspect}" is the text that you type and finally...
^[ is Esc
I would go for:
nnoremap µ :s/^\s*\(\k\+\)\s*=.*/&\rputs "\1 = #{\1.inspect}"/<cr>
:s presents the advantage of doing the job plus matching the assigned variable if any. Doing the same thing with classical commands like yw, p, etc would be more cumbersome.
If the template become more complex, we can rely on template-file expanders as long as they easily permit to call viml function like matchstr(). Of course, in that case I would use mu-template with the following template-file:
VimL:" $Id: {rtp}/template/ruby/inspect.template
VimL: let s:value_start = '¡'
VimL: let s:value_end = '¡'
VimL: let s:reindent = 1
VimL: let s:marker_open = '<+'
VimL: let s:marker_close = '+>'
VimL: let s:varname = matchstr(getline(line('.')-1), '^\s*\zs\k\+\ze\s*=')
VimL: if empty(s:varname) |throw "the previous line don't assign any variable" |endif
puts "¡s:varname¡ = #{¡s:varname¡.inspect}"<++>
VimL:"vim: encoding=utf-8
If you're doing these on the fly, a snipmate snippet could look like this:
${1:error} = '${2:error message here}'
puts "error = #{$1.inspect}"
If, on the other hand you're just wanting to output pre-existing variables for debugging purposes. Nick-Canzoneri's macro may be more useful.
