I can't find if vscode has a such failure. Is there a way to construct a string with N characters?
I explain myselft:
I need to wrote an empty string like this:
foobar = "1111111111111111";
There is 16 times characters '1'. Is there a way, like in Vim, to construct the line like this:
i wrote 'foobar = "' then i'd make a command to repeat 16 times the character 'i'.
I hope it's clear for you.
Here is an easy way using HyperSnips - a snippet extension that can use javascript to produce the output. First the demo:
The HyperSnips snippet:
snippet `"(.+)\*(\d+)=` "expand" A
``
let origStr = m[1];
let howMany = parseInt(m[2]);
let newStr = origStr.repeat(howMany);
rv=`"${newStr}`
``
endsnippet
This code goes inside a <yourLanguage>.hsnips file to have it run only in that language or all.hsnips to run in all files.
I made it to run inside a "" using this key: (.+)\*(\d+)=
The = is really the trigger - it runs automatically - you could change that to be something else. [The key could be shorter if you didn't care about digits being repeated.]
For more on setting up HyperSnips (which is pretty easy) see VSCode Advanced Custom Snippets
There currently is no native way, outside of copy/pasting.
You can use Repeat Paste:
Copies selected text and pastes repeatedly based on user input. Functions like Vim yank, paste, and repeat. For example, in Vim you would select the characters you want to copy then type 30p to paste the selected text 30 times.
Select a char and activate your command palette with CTRL + SHIFT + P and type 'Repeat Paste' and it will prompt you for the quantity.
You can assign a shortcut to this command
You can use the extension Regex Text Generator. You write a Regular Expression that generates your needed text
Type the following in the Generate Box
foobar = "1{16}";

I'm just using vscode prettier, and I was told that hex value should be uppercase as company's standard. I've been through a search and I found their github-issue
that states,
" Personally I prefer uppercase too, but I was asked to do lowercase... But changing this would cause a lot of unnecessary churn for all Prettier users... this decision has been made and is not going to change. An option won't be added." - Sep. 29,2018
So basically, prettier transformed hex value to lowercase, and does not provide an option to change it to uppercase.
I want to ask, have they change their decision now and made an option to transform css hex value to uppercase? And if theres no really option for this in prettier, is there any alternatives to achieve this?
My basic alternative that I used is the idea of #rioV8, however I would prefer to use replace field instead of Transform to UpperCase, I think that would be more quick.
I would like to provide this as answer because it's at least working.
In vscode find #(?:[0-9a-fA-F]{3}){1,2} using regular expression, and replace it with \U$0.
Updated: how to auto transform after save
Follow this link: How to automatically run a "find and replace" after save?
Since \U$0 did not work well, we looked for alternatives.
Search by regular expression
Open a search window with cmd + shift + f, click .*, and execute a regular expression search with #(?:[0-9a-fA-F]{3}){1,2}.
Select the target string
In the search results window, use cmd + a to select all and cmd + shift + l to select the target string.
Open the command palette
Open the command palette with the cmd + shift + p.
Convert to upper case
Type upperor lower on the command palette and execute.
I have a very long sql query
update emplyee_table SET name = 'abc',age='25',address='stackoverflow' WHERE id = 10
I want the above query to get replaced like this by any vscode operation.
update emplyee_table SET name = ?,age=?,address=? WHERE id = 10
You could use find and replace in VSCode along with an appropriate RegEx.
This Regex should work out: '[^';]*'
Ctrl+H will bring up the replace menu - after enabling regex replace (the button looks like .*), replace the pattern '[^';]*' with ?. Ctrl+Alt+Enter will replace all of the matches in the open editor.
Having trouble finding a way to do this, maybe it is not even possible?
In my case, for testing flow of if-statements/user-interaction, am temporarily adding 40 lines of console.log('trigger-fired-1'); throughout our code.
However, to tell them apart would like each to end with a different number, so in this case, numbers one to forty like so:
In the screen recorded gif, to replicate what I am going for, all I did was copy/paste the numbers one to nine. What I really would like is a shortcut key to generate those numbers at the end for me to eliminate that step of typing out each unique number.
Am primarily coding in Visual Studio Code or Sublime Text, and in some cases shortcuts are similar, or at least have same support but for different shortcut keys.
There are a few extensions that allow you to do this:
Text Pastry
Increment Selection
NumberMonger
For Sublime Text, the solution to this problem is the internal Arithmetic command. Something similar may or may not be available in VS Code (possibly with an extension of some sort) but I'm not familiar enough with it to say for sure.
This command allows you to provide an expression of some sort to apply to all of the cursor locations and/or selected text.
By way of demonstration, here's the example you outlined above:
The expression you provide is evaluated once for every selection/caret in the buffer at the time, and the result of the expression is inserted into the buffer (or in the case of selected text, it replaces the selection). Note also that when you invoke this command from the input panel (as in the screen recording) the panel shows you a preview of what the expression output is going to be.
The special variable i references the selection number; selections are numbered starting at 0, so the expression i + 1 has the effect of inserting the selection numbers starting at 1 instead of 0.
The special variable x refers to the text in a particular selection instead. That allows you to select some text and then transform it based on your expression. An example would be to use x * 2 immediately after the above example (make sure all of the selections are still present and wrapping the numbers) to double everything.
You can use both variables at once if you like, as well as anything in the Python math library, for example math.sqrt(i) if you want some really esoteric logs.
The example above shows the command being selected from the command palette interactively, where the expression automatically defaults to the one that you want for your example (i + 1).
If you want to have this as a key binding, you can bind a key to the arithmetic command and provide the expression directly. For example:
{
"keys": ["super+a"],
"command": "arithmetic",
"args": {
"expr": "i+1"
},
},
Try this one ...
its not like sublime
but works g

How to expand a line of code? For example join lines command will do this
before
{
a: 123,
b: 321
}
after
{ a: 123, b: 321 }
And I need to do the opposite,
from this
{ a: 123, b: 321 }
to this
{
a: 123,
b: 321
}
Is there a way to do it? Maybe a plugin? Thanks.
Using the example you provided you could use the splitline plugin

I noticed the example you provided wasn't valid JSON (missing quotes). If it was, or was any other valid type of code you could use the built VS code code formatter:
Press Ctrl/Cmd + Shift + p
Select >Format Document
if you want to do that for JSON file it is doable
select the text and then hit ctrl-shift-F then VS code will format the json object automatically.
Very late but maybe useful to others.
There is also the option to format the selection based on the filetype's default formatter.
Select your code and then emit the command >Format Selection
If you want you can set a personal hotkey to Format Selection in the keyboard shortcuts.
Hint: To open the command prompt enter one of the following commands:
F1
Ctrl + Shift + p
Whether or not the formatter will output it in your desired format is questionable but maybe there's a way to customize that.
If you use a code editor that is setup to 'format on save' you can easily go between joining lines and expanding lines by formatting.
For instance vscode 'join lines' command that you can do by selecting text and then cmd+j will make all code to one line.
If you say have a formatter for whatever language you are writing you just format on save or call format from the command pallet.
My use case was JavaScript bookmarklets, which need to be one line, but I didn't want to write my code that way, so I just 'join lines' then format to edit or save outside the bookmarklet context.
I'd like to add a suffix to all occurrences of a variable in a file (eg. pluralizing a variable number --> numbers).
VSCode offers a multiselect option thru the default "cmd+d", or editor.action.addSelectionToNextFindMatch. However, after I do this over all occurrences of number, the entire variable is selected. I really just need the cursor to be at the very end, so I can add an s. I would like not have to retype numbers.
How can I achieve this?
As an alternative, I use a regex:
\b(var1|var2|var3)\b
And I replace it with the same content $1 (since I capture the variable name in a group with ()) followed by 's': $1s
I would just copy the variable first. So:
Double-click your variable and Ctrl-C
Ctrl-F2 selects all occurences
Ctrl-V and add your 's'
The regex method is better if you have a few variables to change, but not if you have only one or two to change. Really simple to create a macro if you would be doing this a lot - you could get it down to a single keychord.
[This unfortunately selects occurrences of var1 and someOtherVar1 (the Var1 part) - so if this is a problem better to use a regex as it is easier to exclude instances of the var1 term appearing within another word, like someVar1 that you do not intend to change.]
