# @jridgewell/gen-mapping
> Generate source maps
`gen-mapping` allows you to generate a source map during transpilation or minification.
With a source map, you're able to trace the original location in the source file, either in Chrome's
DevTools or using a library like [`@jridgewell/trace-mapping`][trace-mapping].
You may already be familiar with the [`source-map`][source-map] package's `SourceMapGenerator`. This
provides the same `addMapping` and `setSourceContent` API.
## Installation
```sh
npm install @jridgewell/gen-mapping
```
## Usage
```typescript
import { GenMapping, addMapping, setSourceContent, toEncodedMap, toDecodedMap } from '@jridgewell/gen-mapping';
const map = new GenMapping({
file: 'output.js',
sourceRoot: 'https://example.com/',
});
setSourceContent(map, 'input.js', `function foo() {}`);
addMapping(map, {
// Lines start at line 1, columns at column 0.
generated: { line: 1, column: 0 },
source: 'input.js',
original: { line: 1, column: 0 },
});
addMapping(map, {
generated: { line: 1, column: 9 },
source: 'input.js',
original: { line: 1, column: 9 },
name: 'foo',
});
assert.deepEqual(toDecodedMap(map), {
version: 3,
file: 'output.js',
names: ['foo'],
sourceRoot: 'https://example.com/',
sources: ['input.js'],
sourcesContent: ['function foo() {}'],
mappings: [
[ [0, 0, 0, 0], [9, 0, 0, 9, 0] ]
],
});
assert.deepEqual(toEncodedMap(map), {
version: 3,
file: 'output.js',
names: ['foo'],
sourceRoot: 'https://example.com/',
sources: ['input.js'],
sourcesContent: ['function foo() {}'],
mappings: 'AAAA,SAASA',
});
```
### Smaller Sourcemaps
Not everything needs to be added to a sourcemap, and needless markings can cause signficantly
larger file sizes. `gen-mapping` exposes `maybeAddSegment`/`maybeAddMapping` APIs that will
intelligently determine if this marking adds useful information. If not, the marking will be
skipped.
```typescript
import { maybeAddMapping } from '@jridgewell/gen-mapping';
const map = new GenMapping();
// Adding a sourceless marking at the beginning of a line isn't useful.
maybeAddMapping(map, {
generated: { line: 1, column: 0 },
});
// Adding a new source marking is useful.
maybeAddMapping(map, {
generated: { line: 1, column: 0 },
source: 'input.js',
original: { line: 1, column: 0 },
});
// But adding another marking pointing to the exact same original location isn't, even if the
// generated column changed.
maybeAddMapping(map, {
generated: { line: 1, column: 9 },
source: 'input.js',
original: { line: 1, column: 0 },
});
assert.deepEqual(toEncodedMap(map), {
version: 3,
names: [],
sources: ['input.js'],
sourcesContent: [null],
mappings: 'AAAA',
});
```

# @jridgewell/resolve-uri
> Resolve a URI relative to an optional base URI
Resolve any combination of absolute URIs, protocol-realtive URIs, absolute paths, or relative paths.
## Installation
```sh
npm install @jridgewell/resolve-uri
```
## Usage
```typescript
function resolve(input: string, base?: string): string;
```
```js
import resolve from '@jridgewell/resolve-uri';
resolve('foo', 'https://example.com'); // => 'https://example.com/foo'
```
| Input | Base | Resolution | Explanation |
|-----------------------|-------------------------|--------------------------------|--------------------------------------------------------------|
| `https://example.com` | _any_ | `https://example.com/` | Input is normalized only |
| `//example.com` | `https://base.com/` | `https://example.com/` | Input inherits the base's protocol |
| `//example.com` | _rest_ | `//example.com/` | Input is normalized only |
| `/example` | `https://base.com/` | `https://base.com/example` | Input inherits the base's origin |
| `/example` | `//base.com/` | `//base.com/example` | Input inherits the base's host and remains protocol relative |
| `/example` | _rest_ | `/example` | Input is normalized only |
| `example` | `https://base.com/dir/` | `https://base.com/dir/example` | Input is joined with the base |
| `example` | `https://base.com/file` | `https://base.com/example` | Input is joined with the base without its file |
| `example` | `//base.com/dir/` | `//base.com/dir/example` | Input is joined with the base's last directory |
| `example` | `//base.com/file` | `//base.com/example` | Input is joined with the base without its file |
| `example` | `/base/dir/` | `/base/dir/example` | Input is joined with the base's last directory |
| `example` | `/base/file` | `/base/example` | Input is joined with the base without its file |
| `example` | `base/dir/` | `base/dir/example` | Input is joined with the base's last directory |
| `example` | `base/file` | `base/example` | Input is joined with the base without its file |

# @jridgewell/set-array
> Like a Set, but provides the index of the `key` in the backing array
This is designed to allow synchronizing a second array with the contents of the backing array, like
how in a sourcemap `sourcesContent[i]` is the source content associated with `source[i]`, and there
are never duplicates.
## Installation
```sh
npm install @jridgewell/set-array
```
## Usage
```js
import { SetArray, get, put, pop } from '@jridgewell/set-array';
const sa = new SetArray();
let index = put(sa, 'first');
assert.strictEqual(index, 0);
index = put(sa, 'second');
assert.strictEqual(index, 1);
assert.deepEqual(sa.array, [ 'first', 'second' ]);
index = get(sa, 'first');
assert.strictEqual(index, 0);
pop(sa);
index = get(sa, 'second');
assert.strictEqual(index, undefined);
assert.deepEqual(sa.array, [ 'first' ]);
```

# @jridgewell/source-map
> Packages `@jridgewell/trace-mapping` and `@jridgewell/gen-mapping` into the familiar source-map API
This isn't the full API, but it's the core functionality. This wraps
[@jridgewell/trace-mapping][trace-mapping] and [@jridgewell/gen-mapping][gen-mapping]
implementations.
## Installation
```sh
npm install @jridgewell/source-map
```
## Usage
TODO
### SourceMapConsumer
```typescript
import { SourceMapConsumer } from '@jridgewell/source-map';
const smc = new SourceMapConsumer({
version: 3,
names: ['foo'],
sources: ['input.js'],
mappings: 'AAAAA',
});
```
#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
```typescript
const smc = new SourceMapConsumer(map);
smc.originalPositionFor({ line: 1, column: 0 });
```
### SourceMapGenerator
```typescript
import { SourceMapGenerator } from '@jridgewell/source-map';
const smg = new SourceMapGenerator({
file: 'output.js',
sourceRoot: 'https://example.com/',
});
```
#### SourceMapGenerator.prototype.addMapping(mapping)
```typescript
const smg = new SourceMapGenerator();
smg.addMapping({
generated: { line: 1, column: 0 },
source: 'input.js',
original: { line: 1, column: 0 },
name: 'foo',
});
```
#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
```typescript
const smg = new SourceMapGenerator();
smg.setSourceContent('input.js', 'foobar');
```
#### SourceMapGenerator.prototype.toJSON()
```typescript
const smg = new SourceMapGenerator();
smg.toJSON(); // { version: 3, names: [], sources: [], mappings: '' }
```
#### SourceMapGenerator.prototype.toDecodedMap()
```typescript
const smg = new SourceMapGenerator();
smg.toDecodedMap(); // { version: 3, names: [], sources: [], mappings: [] }
```

# @jridgewell/sourcemap-codec
Encode/decode the `mappings` property of a [sourcemap](https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit).
## Why?
Sourcemaps are difficult to generate and manipulate, because the `mappings` property the part that actually links the generated code back to the original source is encoded using an obscure method called [Variable-length quantity](https://en.wikipedia.org/wiki/Variable-length_quantity). On top of that, each segment in the mapping contains offsets rather than absolute indices, which means that you can't look at a segment in isolation you have to understand the whole sourcemap.
This package makes the process slightly easier.
## Installation
```bash
npm install @jridgewell/sourcemap-codec
```
## Usage
```js
import { encode, decode } from '@jridgewell/sourcemap-codec';
var decoded = decode( ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
assert.deepEqual( decoded, [
// the first line (of the generated code) has no mappings,
// as shown by the starting semi-colon (which separates lines)
[],
// the second line contains four (comma-separated) segments
[
// segments are encoded as you'd expect:
// [ generatedCodeColumn, sourceIndex, sourceCodeLine, sourceCodeColumn, nameIndex ]
// i.e. the first segment begins at column 2, and maps back to the second column
// of the second line (both zero-based) of the 0th source, and uses the 0th
// name in the `map.names` array
[ 2, 0, 2, 2, 0 ],
// the remaining segments are 4-length rather than 5-length,
// because they don't map a name
[ 4, 0, 2, 4 ],
[ 6, 0, 2, 5 ],
[ 7, 0, 2, 7 ]
],
// the final line contains two segments
[
[ 2, 1, 10, 19 ],
[ 12, 1, 11, 20 ]
]
]);
var encoded = encode( decoded );
assert.equal( encoded, ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
```

# @jridgewell/trace-mapping
> Trace the original position through a source map
`trace-mapping` allows you to take the line and column of an output file and trace it to the
original location in the source file through a source map.
You may already be familiar with the [`source-map`][source-map] package's `SourceMapConsumer`. This
provides the same `originalPositionFor` and `generatedPositionFor` API, without requiring WASM.
## Installation
```sh
npm install @jridgewell/trace-mapping
```
## Usage
```typescript
import {
TraceMap,
originalPositionFor,
generatedPositionFor,
sourceContentFor,
} from '@jridgewell/trace-mapping';
const tracer = new TraceMap({
version: 3,
sources: ['input.js'],
sourcesContent: ['content of input.js'],
names: ['foo'],
mappings: 'KAyCIA',
});
// Lines start at line 1, columns at column 0.
const traced = originalPositionFor(tracer, { line: 1, column: 5 });
assert.deepEqual(traced, {
source: 'input.js',
line: 42,
column: 4,
name: 'foo',
});
const content = sourceContentFor(tracer, traced.source);
assert.strictEqual(content, 'content for input.js');
const generated = generatedPositionFor(tracer, {
source: 'input.js',
line: 42,
column: 4,
});
assert.deepEqual(generated, {
line: 1,
column: 5,
});
```
We also provide a lower level API to get the actual segment that matches our line and column. Unlike
`originalPositionFor`, `traceSegment` uses a 0-base for `line`:
```typescript
import { traceSegment } from '@jridgewell/trace-mapping';
// line is 0-base.
const traced = traceSegment(tracer, /* line */ 0, /* column */ 5);
// Segments are [outputColumn, sourcesIndex, sourceLine, sourceColumn, namesIndex]
// Again, line is 0-base and so is sourceLine
assert.deepEqual(traced, [5, 0, 41, 4, 0]);
```
### SectionedSourceMaps
The sourcemap spec defines a special `sections` field that's designed to handle concatenation of
output code with associated sourcemaps. This type of sourcemap is rarely used (no major build tool
produces it), but if you are hand coding a concatenation you may need it. We provide an `AnyMap`
helper that can receive either a regular sourcemap or a `SectionedSourceMap` and returns a
`TraceMap` instance:
```typescript
import { AnyMap } from '@jridgewell/trace-mapping';
const fooOutput = 'foo';
const barOutput = 'bar';
const output = [fooOutput, barOutput].join('\n');
const sectioned = new AnyMap({
version: 3,
sections: [
{
// 0-base line and column
offset: { line: 0, column: 0 },
// fooOutput's sourcemap
map: {
version: 3,
sources: ['foo.js'],
names: ['foo'],
mappings: 'AAAAA',
},
},
{
// barOutput's sourcemap will not affect the first line, only the second
offset: { line: 1, column: 0 },
map: {
version: 3,
sources: ['bar.js'],
names: ['bar'],
mappings: 'AAAAA',
},
},
],
});
const traced = originalPositionFor(sectioned, {
line: 2,
column: 0,
});
assert.deepEqual(traced, {
source: 'bar.js',
line: 1,
column: 0,
name: 'bar',
});
```
