EDIT: try this snippet:

<pre><code>"latex labels": {
 "prefix": "_ll",
 "body": [
 "\\section{$1}",
 "\\label{sec:${2:${1/(\\w*)((æ)|(ø)|(å)|(é)|(\\s+)|([^a-zA-Z0-9_ ]))/${1:/downcase}${3:+ae}${4:+oe}${5:+aa}${6:+e}${7:+_}/gi}}}",
 ],
 "description": "Transform to latex labels"
},
</code></pre>

If you have more Danish characters you will have to add them individually - vscode does not support the <code>/asciify</code> transform.

<hr>

Previous Answer:

I really don't think you can do it in one regex. Which means a normal snippet will not work. A macro can run as many snippet transforms as you want though.

Using the macro extension <a href="https://marketplace.visualstudio.com/items?itemName=ryuta46.multi-command" rel="nofollow noreferrer">multi-command</a> put this into your settings.json:

<pre><code> "multiCommand.commands": [

 {
 "command": "multiCommand.latexLabelTransform",
 "sequence": [
 "cursorHomeSelect",
 "editor.action.clipboardCopyAction",
 {
 "command": "editor.action.insertSnippet",
 "args": {
 "snippet": "${TM_SELECTED_TEXT/(æ)|(ø)|(å)/${1:+ae}${2:+oe}${3:+aa}/gi}"
 }
 },
 "cursorHomeSelect",
 {
 "command": "editor.action.insertSnippet",
 "args": {
 "snippet": "${TM_SELECTED_TEXT/(.*)/${1:/downcase}/}"
 }
 },
 "cursorHomeSelect",
 {
 "command": "editor.action.insertSnippet",
 "args": {
 "snippet": "${TM_SELECTED_TEXT/[^a-z0-9 ]//g}"
 }
 },
 "cursorHomeSelect",
 {
 "command": "editor.action.insertSnippet",
 "args": {
 "snippet": "\\section {$CLIPBOARD} \\label{sec:${2:${TM_SELECTED_TEXT/\\s/_/g}}}"
 }
 }
 ]
 }
 ]
</code></pre>

And some keybinding:

<pre><code>{
 "key": "alt+d",
 "command": "extension.multiCommand.execute",
 "args": { "command": "multiCommand.latexLabelTransform" }
},
</code></pre>

If you are starting with the text, for example <code>Ørne og Mus!</code> see the following demo:

<a href="https://i.stack.imgur.com/igeJr.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/igeJr.gif" alt="latex snippet transform"></a>

<hr>

The transformed part is selected as seen in the demo. Cursor at end of text before triggering the macro. I could probably get it to work starting with <code>\section {yourTextHere}</code> as well if need be.

I tried to get it to work as a regular snippet but it doesn't seem to be a way to get the multiple transforms that you want done in a single transform.

Let me know if this works for you.

blocks|key|805766|text|好吧，那么我可能最终找到了一个解决方案，作为一个片段|type|unstyled|depth|inlineStyleRanges|entityRanges|data|805767|"\\section{$1}",
"\\label{sec:${2:${1/(æ)%7C(ø)%7C(å)%7C(é)%7C(+%2B)%7C[%5EA-Za-z0-9]/${1:%2Bae}${2:%2Boe}${3:%2Baa}${4:%2Be}${5:%2B_}/g}}}",|code-block|syntax|javascript|805768|我只发现了几个问题。|805769|我必须手动将重音字母添加到列表中，例如|ordered-list-item|805770|无停机情况|805771|如果有一个字符串表示"！！"，它将被替换为两个下划线，而不是1，因为空格之间有一个间隙。|805772|有人知道该怎么改变吗？或者我甚至可以为这种类型的regex找到一个很好的资源(我还没有找到)|805773|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|U|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|V|8|@]|9|@]|A|$]]|$1|I|3|J|5|K|7|W|8|@]|9|@]|A|$]]|$1|L|3|M|5|K|7|X|8|@]|9|@]|A|$]]|$1|N|3|O|5|K|7|Y|8|@]|9|@]|A|$]]|$1|P|3|Q|5|6|7|Z|8|@]|9|@]|A|$]]|$1|R|3|-4|5|6|7|10|8|@]|9|@]|A|$]]]|S|$]]

Okay, so I might have found a solution finally that works as a snippet

<pre><code>"\\section{$1}",
"\\label{sec:${2:${1/(æ)|(ø)|(å)|(é)|( +)|[^A-Za-z0-9]/${1:+ae}${2:+oe}${3:+aa}${4:+e}${5:+_}/g}}}",
</code></pre>

Only a couple of issues i've found.

<ol>
<li>I have to manually add accented letters to the list such as é</li>
<li>No downcase</li>
<li>If there is a string say "! ! ", it gets replaced with two underscores instead of 1, as there is a break in between the spaces.</li>
</ol>

Anyone have an idea of how that could be changed? Or where I can even find a good resource for this type of regex (I haven't been able to find one)

I've tried for day to get snippets to work with regex, but I can't seem to wrap my head around a way of doing it.

The usecase is writing LaTeX, specifically sections with automatic labeling. I have some issues with labelling, since LaTeX doesn't allow certain danish characters in the labels. Therefore, I would like for the snippet to take care of the replacements itself, as well as some other formatting. That means that I want the following:

<ol>
<li>Make everything lowercase</li>
<li>Change letters "æ", "ø" and "å" to "ae", "oe" and "aa"</li>
<li>Remove special characters (so characters are only a-z and 0-9)</li>
<li>Change spaces to "_"</li>
</ol>

Lastly, I would like to highlight the "transformed" text, so I can change it to something different if I need to (in case of duplicate labels).

The snippet would look like the following:

<pre class="lang-latex prettyprint-override"><code>\section{$1} \label{sec:${2:$1(after regex)}
</code></pre>

Hope that makes any sense at all

The transformation would do the following

Ørne og Mus! -> oerne_og_mus

This is doable in Textmate with the following snippet

<pre class="lang-latex prettyprint-override"><code>\section{${1:section name}}
\label{sec:${2:${1/(\w+)(\W+$)?|\W+/${1:?${1:/asciify/downcase}:_}/g}}}
</code></pre>

But this is not compatible with VS code. Can this somehow be altered to work with VS code?
