node-ts-dedent's Issues

Could you please explain exactly what it does in the docs?

Based on the examples, I think it removes a starting bare newline, and then removes the number of whitespace characters on the first line that starts with whitespace characters. Or does it remove the number of whitespace characters on the line with the fewest leading whitespace characters?

A quick summary of what the algorithm is would make it easier than having to look in the code or try stuff.

Handle interpolations properly

import dedent from 'ts-dedent'

const fieldDocs = dedent`
  * a
  * b
  * c
`

const a = dedent`
  /**
   ${fieldIntro()}
   *
   ${fieldDocs}
   *
   ${fieldExample()} 
   */
`

function fieldIntro() {
  return dedent`
    * 0
  `
}
function fieldExample() {
  return dedent`
    * d
  `
}

console.log(a)

Expected

/**
 * 0
 *
 * a
 * b
 * c
 *
 * d 
 */

Actual

/**
 * 0
 *
 * a
* b
* c
 *
 * d 
 */

ts typings error

Got error :

error TS7016: Could not find a declaration file for module 'dedent'. '.../node_modules/dedent/dist/dedent.js' implicitly has an 'any' type.
Try npm install @types/dedent if it exists or add a new declaration (.d.ts) file containing declare module 'dedent';

Can you please publish @types/ts-dedent? That would help.

Dedenting doesn't work when using on stored strings

I had my string stored in a variable, and used dedent on it.

        const string = `
        Leading and trailing lines will be trimmed, so you can write something like
        this and have it work as you expect:
       
          * how convenient it is
          * that I can use an indented list
              - and still have it do the right thing
       
        That's all.
      `;
        const dedentedString1 = dedent`
        Leading and trailing lines will be trimmed, so you can write something like
        this and have it work as you expect:
       
          * how convenient it is
          * that I can use an indented list
              - and still have it do the right thing
       
        That's all.
      `;
        const dedentedString2 = dedent`
      ${string}
    `;

dedentedString2 did not dedent the string at all.

        Leading and trailing lines will be trimmed, so you can write something like
        this and have it work as you expect:
       
          * how convenient it is
          * that I can use an indented list
              - and still have it do the right thing
       
        That's all.

Not sure if this is a feature request or a bug.

__vite_ssr_import_1__.default is not a function

Reproduce Link

https://codesandbox.io/p/devbox/vigilant-mcclintock-dgvccf?file=%2Fsrc%2Flayouts%2FLayout.astro%3A21%2C13

Description

Using dedent anywhere with astro@v4 will cause an error __vite_ssr_import_1__.default is not a function

[bug] if there is no indent output is wrong

input:

var tsDedent = require("ts-dedent").default

const text = `
clone:
      disable: true
`
console.log(tsDedent(text))

Paste above on runkit to test https://npm.runkit.com/ts-dedent

output:

clone:
disable: true

Remove trailing spaces on empty lines in interpolated text

See indentjs/endent#12 for an example failing test.

const insertion = "indented 1\n\nindented 2";
const output = endent`
  foo
    ${insertion}
`;
const current = output === "foo\n  indented 1\n  \n  indented 2"
const desired = output === "foo\n  indented 1\n\n  indented 2"

I have worked around this by tacking .replaceAll(/\n\s*\n/gi, '\n\n') at the end of our dedent() calls in a wrapper function.

Unicode Escape Sequence Handling

Feature request: unicode escape sequence handling.

import dedent from 'dedent';

console.log(`\u00E4`); // Prints ä
console.log(dedent`\u00E4`); // Prints \u00E4 - expected ä

Backticks (possibly) cause no dedent

I've got a weird one for you, one that seems to be a problem in the older dedent package as well (dmnd/dedent#26). Escaped backticks result in no dedent-ing.

const content = '    [APBannerManager showBannerWithTitle:@"Title"\n' +
    '                                          subtitle:@"Subtitle"\n' +
    '                                          body:@"Body"\n' +
    '                                          image:[UIImage imageNamed:@"myPicture"]\n' +
    '                                          actionBlock:^(APBannerActionType type) {\n' +
    '                                            switch (type) {\n' +
    '                                              case APBannerActionTypeTap:\n' +
    '                                                NSLog(@"TAP");\n' +
    '                                                break;\n' +
    '                                              case APBannerActionTypeDismiss:\n' +
    '                                                NSLog(@"DISMISS");\n' +
    '                                                break;\n' +
    '                                            }\n' +
    '                                          }];';
   dedent(`\`\`\`
${content}
\`\`\``);

What we end up with is:
