I found that when you type.print at the end of the line in pycharm, it will automatically convert this line to print(line). So I want to know whether vscode can achieve such a function with snippet.
I have written a snippet after googling.
"print": {
"prefix": "print",
"body": "\nprint(${TM_CURRENT_LINE-})"
}
However, there is a problem in this snippet: the prefix will be added during conversion. Besides, it only adds an additional line instead of changing the current line.
demonstration of snippet now
you can do it like this：
".print": {
"prefix": ".print",
"body": ["\nprint(${TM_CURRENT_LINE/(^.+)(\\..+)/$1/g})"],
}

i have many pieces of code same for example like this
alt="Greece"
alt="Greece"
alt="Greece"
alt="Greece"
Can i somehow modify it to this? Is there any kind of function like in Excel or something like that please? Imagination write it manualy each is horrible
alt="Greece 1"
alt="Greece 2"
alt="Greece 3"
...
alt="Greece 200"
You can use the extension Regex Text Generator
select the word Greece
select all cases you want with
Ctrl+D multiple times
Ctrl+Shift+L to select all
use Shift+Alt+Click to create multiple cursors
if needed RightArrow to get all cursors after the word Greece
execute command: Generate text based on Regular Expression (regex)
As Original Text Regex use: .*
As Generator Regex use: {{=i+1}} (watch the space as first char)
Look at the preview, use Esc to cancel and Enter to accept
You can use any calculation based on i you want and you can also match number in the selected text and use that in the calculation N[...].
You can also add the word Greece by using Greece {{=i+1}}
You have a couple of options. First, using the extension, Find and Transform (disclaimer, I wrote that extension, this is very easy. Make this keybinding in your keybindings.json (after installing the extension):
{
"key": "alt+n", // whatever keybinding you like
"command": "findInCurrentFile",
"args": {
"find": "(alt=\"Greece\")",
"replace": "$1 ${matchNumber}",
"isRegex": true
}
},
Actually you can make it even easier if you first select what you want to modify (see the demo below). Then use this simple keybinding:
{
"key": "alt+n",
"command": "findInCurrentFile",
"args": {
"replace": "$1 ${matchNumber}", // what you select will be put into $1
"isRegex": true
}
},
Another option - not quite as easy
Snippets have a variable $CURSOR_NUMBER which is useful here.
Make this keybinding:
{
"key": "alt+n",
"command": "editor.action.insertSnippet",
"args": {
"snippet": "$TM_SELECTED $CURSOR_NUMBER"
},
"when": "editorHasSelection"
},
Do a find on your desired text match: alt="Greece"
Ctrl+Shift+L to select all occurrences of the find match.
Trigger the snippet via its keybinding.
Demo of this method:
So this second method is more steps but doesn't require an extension.
I'm trying to understand how the web-scraping is done in Huginn but I cannot find proper documentation on the options available.
I'd like to extract the price of the Gold oz. from this website for example:
https://www.xe.com/currencyconverter/convert/?Amount=1&From=XAU&To=USD
For which I use a Huginn Website Agent with this code:
{
"expected_update_period_in_days": "2",
"url": "https://www.xe.com/currencyconverter/convert/?Amount=1&From=XAU&To=USD",
"type": "html",
"mode": "on_change",
"extract": {
"price": {
"css": ".converterresult-toAmount",
"value": "."
}
}
}
I got the css selector using SelectorGadget and I've tried multiple values like: ./node(), string(.), normalize-space(.), . , //text() and others, but I cannot find the way to extract the content of the span html tag that contains that value. Here the code of that section of the web:
<span class="converterresult-toAmount">1,730.35</span>
And what I want to extract is: 1,730.35
i got it working on another site.
i used "xpath" for it.
I used a different site because it wouldn't work on the one you posted.
But i hope this still helps someone.
{
"expected_update_period_in_days": "2",
"url": "https://walletinvestor.com/converter/xau/usd/1",
"type": "html",
"mode": "on_change",
"extract": {
"gold_in_dollar_price": {
"xpath": "/html/body/div[4]/div/div[3]/div[1]/h2/strong/span",
"value": "string(.)"
}
}
}
Here is how you get the XPath of any Element/Object on a website:
(i used Yandex Browser based on chrome for this)
Open the Developer Tools in the Browser (or right click and select "Inspect element code")
Select / Click with the Inspector on your Element/Object
You should now see something like:
<span class="converterresult-toAmount">1,730.35</span>
Right click on this and click: "copy" > "Copy XPath"
Im using Huginn since 2 Days so anyone feel free to tell me any faster way if there is any :)
How do I create a custom snippet that will automatically enter a variable's value that I type into its prefix?
I want a snippet that will create a html start-end tag comment block. For example if I type /se hello I want the result to be
<!-- $var start-->
<!-- $var end-->
Where $var is replaced with "hello". Thank you for reading!
As the VSCode snippet docs says, it uses TextMate to power its snippets. TextMate uses variables of the form $name and ${name:default}, and luckily supplies $TM_CURRENT_WORD which may be sufficient for your needs. However there is no built in variable to get multiple arguments directly after the snippet name i.e. $arg1 and $arg2 as variables. Thought you could do a similar effect with interpolated shell code, but unfortunately:
The snippet syntax follows the TextMate snippet syntax with the exceptions of 'interpolated shell code' and the use of \u; both are not supported.
Emphasis mine
However for this simple example, the following indexed variable example is probably sufficient.
<!-- $1 start-->
$0
<!-- $1 end-->
$i gives you a value to fill in, you can go between each one with tabbing. The $0 is where the cursor goes at the end(the end of the snippet by default). Optionally you can do something like:
<!-- ${1: default text} start-->
$0
<!-- $1 end-->
and it'll start looking like:
<!-- default text start-->
<!-- default text end-->
with both of the defaults selected to edit.
This all put together would look like this together in the snippets.json file:
{
"se": {
"scope": "html",
"prefix": "se",
"body": [
"<!-- ${1:default text} start-->",
"\t$0",
"<!--$1 end-->"
]
}
}
As #Mark pointed out, if you want it to work for more than just HTML you can use $BLOCK_COMMENT_START and $BLOCK_COMMENT_END which will vary for each language. The snippet would then look like this:
{
"se": {
// Leaving scope off will make it a global snippet
"prefix": "se",
"body": [
"$BLOCK_COMMENT_START ${1:default text} start $BLOCK_COMMENT_END",
"\t$0",
"$BLOCK_COMMENT_START$1 end $BLOCK_COMMENT_END"
]
}
}
I am trying to use the Sublime Text Plugin RegReplace package so I can highlight a line of text and replace spaces with dashes.
Goal
Hello My Name is Jesse, Highlight, CTRL + . replaces with:
Hello-My-Name-is-Jesse -- for the purpose for saving time creating markdown links.
Currently Working, But Runs Entire File
I would really like this to only replace the text I have highlighted wit a hotkey, is this possible?
I have this in reg_replace_rules.sublime-settings
{
"replacements": {
"replace_spaces_with_dash": {
"find" : "(\\s)",
"replace": "-",
"greedy": true,
"case": false
}
}
}
Here is my User Hotkeys
{
"keys": ["ctrl+."],
"command": "reg_replace",
"args": {"replacements": ["replace_spaces_with_dash"]}
},
However, this replaces the entire file with spaces. I am missing something I hope, I am not sure the scope. Any help would be appreciated.
SublimeText completion using .sublime-completions file fails to work on HTML attribute, inside the quotes. Typing the trigger (test in the example below) inside the alt="" attribute does not insert the completion. It does outside the image tag without problems. Any suggestions why?
Scope inside the quotes is matching the definition in the html-attr.sublime-completions file below: text.html.basic meta.tag.inline.any.html string.quoted.double.html punctuation.definition.string.end.html.
<body>
<img src="/images/poster.jpg" alt="">
</body>
I am using .sublime-completions file:
// html-attr.sublime-completions
{
"scope": "text.html.basic meta.tag.inline.any.html string.quoted.double.html punctuation.definition.string.end.html",
"completions":
[
{
"trigger": "test",
"contents": "test ok"
}
]
}
Other installed packages include Emmet, HTML5, Better Completion, HTMLAttributes and SublimeCodeIntel, but disabling them all does not help the situation.
// Preferences.sublime-settings
{
"auto_complete": true,
}
Update:
Emmet could have been a culprit, but not my case. Emmet overrides completions defined by .sublime-completions files, unless Emmet's tab_abbreviation is disabled for the corresponding scope:
// Emmet.sublime-settings
"disable_tab_abbreviations_for_scopes": "text.html.basic"
I solved the problem temporarily by using .sublime-snippet, but it didn't work on the XML files so well. Still looking for an answer to the question above.
<!-- html-attr.sublime-snippet -->
<snippet>
<content>test ok</content>
<tabTrigger>test</tabTrigger>
<scope>text.html.basic</scope>
<description>html-attr.sublime-completion does not work</description>
</snippet>
