I have a TDrawGrid where I am using its OnDrawCell event, and in there the Canvas.TextRect() method is used to fill out the cells with strings. One of the strings contains an &, but it gets displayed as an underscore _.
I don't see anything wrong, there is nothing fancy with this grid, and elsewhere it seems to work fine. Also the debugger confirms that the string is correct when passing it to Canvas.TextRect().
What am I missing?
Delphi 11, 64-bit, Windows 11.
This is expected. In Microsoft Windows, menu items, buttons, and control labels use an underscore to indicate the corresponding keyboard shortcut, and this underlined character is indicated using a prefix ampersand in code.
For instance, the &File menu item (displayed as File with F underlined) can be accessed by pressing Alt+F. A &Save button (displayed as Save with S underlined) may be invoked by pressing Alt+S (or only S if the currently focused control doesn't accept character input). You can set focus to a text field with label &Name: (displayed as Name: with N underlined) by pressing Alt+N.
This is why a string like Lost & Found is displayed as Lost _Found in Windows.
If you don't want ampersands to be treated as accelerator character indicators, simply use the tfNoPrefix flag:
Canvas.TextRect(R, S, [tfNoPrefix])
This VCL flag corresponds to the Win32 API DT_NOPREFIX flag:
Turns off processing of prefix characters. Normally, DrawText interprets the mnemonic-prefix character & as a directive to underscore the character that follows, and the mnemonic-prefix characters && as a directive to print a single &. By specifying DT_NOPREFIX, this processing is turned off.

I am tryng to get rid of shortcodes inside a Google Sheet column. I have many items such as [spacer type="1" height="20"][spacer] or [FinalTilesGallery id="37"] I just would like to cancel them. Is there any simple way to do it?
Thanks !
For in-place replacement, the quick option would be to use the Find and Replace dialog (Ctrl + H) with Search Using Regular Expressions turned on, which is more powerful than your standard Find and Replace.
Find: \[.*?\] - Match anything within an open-bracket up to the very next close-bracket. This should work assuming you have no nested brackets, e.g. [[no][no]].
If you do have nested brackets, you'll have to change this to \[[^\[\]]*\]. And continue to Replace All until all the codes are gone.
Replace: Nothing.
Replace All. If you don't want to affect other sheets that may be in your document, make sure you select the right range to work with, too.
This just erases everything within the brackets.
If you want to erase any redundant spaces left by this, simply Find and Replace again (with Regular Expressions) on + (space and plus), which will match 1 or more spaces and replace with (single space).
E.g.:
string [] [] string2 -> string string2 after the shortcode replacement.
After replacing spaces, it will become string string2.
Let's say your original strings are in the range A2:A. Place the following into B2 of an otherwise completely empty Column B (or the second cell of any other empty column):
=ArrayFormula(IF(A2:A="",,TRIM(REGEXREPLACE(A2:A,"\[[^\[\]]+\]",""))))
I can't see your data, so I don't know what kind of information is between these shortcodes. If you find that this leaves you with concatenated pieces of data where there should be spaces between them, replace the above with this version:
=ArrayFormula(IF(A2:A="",,TRIM(REGEXREPLACE(SUBSTITUTE(SUBSTITUTE(A2:A,"["," ["),"]","] "),"\[[^\[\]]+\]",""))))
I can't teach regular expression language here. But I will note that, since square brackets have specific meaning within regex, your literal square brackets must be indicated with the escape character: the backslash.
Here is the regex expression alone:
\[[^\[\]]+\]
The opening \[ and the closing \], then, reference your actual opening and closing bracket sets. If we remove those, we have this left:
[^\[\]]+
Again, you see the escaped opening and closing square brackets, which I'll replace with the word these:
[^these]+
What remains there are opening and closing brackets with regex meaning, i.e., "anything in this group." And the circumflex symbol ^ as the first character within this set of square brackets means "anything except." The + symbol means "in any string length of one or more characters."
So that whole regex expression then reads: "A literal open square bracket, followed by one or more characters that are anything except square brackets, ending with a literal closing square bracket."
And we are REGEXREPLACE-ing any instance of that with "" (i.e., nothing).
Here is a simple lists where I like to change the numbers: the entries are as below and it got over 300 entries like it
tom112
smith113
harry114
linda115
cindy106
samantha147
It need to be changed to
tom212
smith213
harry214
...and so on.
Please assist using notepad++ regular expression.
Thanks.
Assuming it's just a matter of replacing a name followed by a number starting with 1 with the same number but starting with 2 instead:
Ctrl + H for search & replace.
Check Regular expression under Search Mode.
Next to Find what type or copy in ([a-zA-Z]+)1([0-9]+).
Next to Replace with type or copy in \12\2.
Click Replace All and that should do it.
Add any other characters that might appear in the name before the number inside the first set of brackets with a-zA-Z.
title says everything plus:
- development language Lua
- code revision control system - Perforce (integrated with IntelliJ IDE)
Posting for posterity - This was the top Google entry when searching "intellij count lines of code" (without quotes)
.
If you're like me and didn't want to install anything else, you can hack it via the native, global search:
Ctrl + Shift + F (to open global search)
Use regex mode (check "regex" checkbox)
In the searchbox, enter only a caret "^" (without the quotes)
You may want to limit the search to a specific directory, via the "directory" tab
Hit the "Open in Find Window" button on the bottom-right
If it asks whether you want to continue, press "Continue"
.
Notes:
In regex, the caret (^) denotes the start of a line, except when inside square brackets, in which case it denotes negation
If you wanted to count non-empty lines, you could instead use "^.*\S" (without quotes), which signifies "The start of a line (^), followed by any number of characters (except newline) (.*), followed by a non-whitespace character (\S)"
You can either turn on the display of lines of code for a single file by right clicking in the left gutter and highlighting "display lines of code". Or you can do it for your entire project by downloading the Statistic plug-in. It's very nice indeed, because it shows LOC and other metrics for your entire project.
I usually use Geany or Hi-Tide under Debian (GNU/Linux) for firmware development, mainly C (but also reading old assembler). I document code using single-line comments, and it really annoys me when I retype something and have to manually re-break every following line to keep it in the 80-character margin.
Is there a text editor that can re-wrap consecutive single-line comments (and do this automatically while I type)? That is, given:
/// This is a really long line that should have been wrapped at "that" but was not.
/// This sentence is in the same
/// paragraph as the last.
...I want an editor that will re-wrap this to
/// This is a really long line that
/// should have been wrapped at "that"
/// but was not. This sentence is in
/// the same paragraph as the last.
...preferably doing this sensibly while I type.
I've tried:
Hi-Tide (based on Eclipse 3.3)
Geany
jEdit
UniversalIndentGUI + a bunch of prettifiers (I couldn't find any formatters that worked, and it's not a great workflow either)
GVim - next line begins //should have been... instead of /// should have been...
Update: just to elaborate on my accepted answer - I've gone with the snapshot emacs and an extra filladapt mode was also required
In Emacs, to start automatic wrapping, enter auto-fill-mode. To set the line width, run C-u ⟨columns⟩ C-x f.
Emacs, or really CC Mode, will anticipate your commenting structure, so that typing
/// This is a really long line that shoul will result in
/// This is a really long line that
/// shoul‸
And you can refill a paragraph at any time with M-q.
If you want to do refills automatically with each keypress, well there may well be some interal command or third-party library out there, but off-hand you can use this elisp code:
;;; Can't advise SELF-INSERT-COMMAND, so create a wrapper procedure.
(defun self-insert-refill (n)
(interactive "p")
(self-insert-command n))
;;; Advise SELF-INSERT-REFILL to execute FILL-PARAGRAPH after every
;;; keypress, but *only* if we're inside a comment
(defadvice self-insert-refill (after refill-paragraph)
(let ((face (or (get-char-property (point) 'read-face-name)
(get-char-property (point) 'face))) )
(if (and (eq face 'font-lock-comment-face)
(not (string= " " (this-command-keys)))) ; Spaces would get deleted on refill.
(fill-paragraph))))
(ad-activate 'self-insert-refill)
(add-hook 'c-mode-hook
;; Remap SELF-INSERT-COMMAND to be SELF-INSERT-REFILL.
(local-set-key [remap self-insert-command] 'self-insert-refill) ))
This is probably not very robust or in keeping with best-practice, and likely not wholly satisfactory, as it won't work for general editing, e.g. C-d and backspace, and it slows down the editor somewhat, but it's a start.
Vim most certainly can do this.
First, you need to tell Vim that "///" is a comment prefix (it isn't by default):
:set comments^=:///
If you want wrapping to occur as-you-type, set your preferred textwidth:
:set textwidth=80
To format existing paragraphs, use any variation of the gq command. For example, you could:
Select a paragraph visually and type gq, or
Type gqj to re-wrap from the current line to the end of the paragraph
vi treats dash - and space as word separators for commands such as dw and cw.
Is there a way to add underscore _ as well?
I quite often want to change part of a variable name containing underscores, such as changing src_branch to dest_branch. I end up counting characters and using s (like 3sdest), but it would be much easier to use cw (like cwdest).
Is there a way to add underscore _ as well?
:set iskeyword-=_
What is, and is not a member character to keywords depends on the language. For help on iskeyword use :help iskeyword.
In case you're using vim, you can change that by setting the iskeyword option (:he iskeyword). If that is not an option, you can always use ct_ instead of counting.
One other good option in such cases is to use camelcasemotion plugin.
It adds new motions ,b, ,e, and ,w, which work analogously with b, e, and w, except that they recognize CamelCase and snake_case words. With it you can use
c,edest
and this will replace "src_branch" with "dest_branch" if your cursor was on first character of "src_branch".
You could type cf_dest_ and save the counting part.
Edit: or as suggested: ct_ changes text until right before the underline character. (I'm using the f motion more, so it came more naturally to me)
Or you could redefine 'iskeyword' (:help iskeyword for details).
I was just looking at this myself and added this to my .vimrc:
set iskeyword=!-~,^*,^45,^124,^34,192-255,^_
My .vimrc had issues with ^| and ^", which was part of the default iskeyword for my setup, so I changed to their ascii values and it works fine. My main modification was to add "^_" to the end of the default setting to keep vim from seeing underscore as being part of a word.
To delete to the next underscore enter "df_"
To change to the next underscore enter "cf_"
NOTE: don't include the double quotes.
