Quick Utils — things to try

Not shipped in the VSIX. This file exists so that pressing F5 opens something you can immediately select text in.

Select any block below and press Ctrl+Alt+T (Cmd+Alt+T on macOS).

Case conversion

XMLHttpRequest
html5Parser
foo_bar-baz.qux
ÜberGrößeWert

With nothing selected, put the cursor inside a word — case transforms take the word under the cursor.

Encoding

5pel5pys6Kqe44Gu44OG44Kt44K544OI

That is Base64. Decode it, then encode it back. Now try decoding this prose instead — it should refuse rather than produce garbage:

this is not base64 at all

Hex, URL and HTML codecs are in the same picker:

<a href="/search?q=a b&lang=ja">リンク</a>

Lines

Select all four lines, then try sort, numeric sort and remove-duplicates:

item10
item9
Apple
apple

JSON

Select the object and try Format JSON, Minify JSON and Sort JSON Keys. Then break it — delete a brace — and watch the error name the position instead of mangling the document.

Statistics

Select this paragraph and look at the status bar; then run Quick Utils: Inspect Selection for the full breakdown.

日本語の文章は空白で区切られないので、空白分割では単語数が 1 になります。 Intl.Segmenter は辞書に基づいて区切るため、ここでは実際の語数が出ます。

Emoji are one grapheme and several code points: 👨‍👩‍👧‍👦 🇯🇵 é

Hashing

Select the line below and run Quick Utils: Hash Selection…. With nothing selected it copies the digest of this whole file instead.

The quick brown fox jumps over the lazy dog

Generators

Put a cursor on each of the three lines below (Alt+Click) and run Insert UUID (v4) — each cursor gets a different value, in one undo step.

Regex Tester

Run Quick Utils: Open Regex Tester, click From editor, and try:

  • (?<user>\w+)@(\w+\.\w+) against the addresses below
  • \p{Script=Han}+ with flags gu against the Japanese paragraph above
  • (a+)+$ against aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaab — this is the catastrophic case; it is abandoned after the configured timeout instead of freezing the editor
alice@example.com
bob@example.co.jp
carol+tag@sub.example.org

Replace by Pattern

With the addresses above selected, run Quick Utils: Replace by Pattern… and replace (\w+)@([\w.]+) with $2/$1.
