* Explode the options table
The options table in README was getting a bit unwieldy. This commit moves the options to a top-level section, and makes each setting hyperlink-able.
The `cursorOffset` setting has been moved from the list to the documentation for `formatWithCursor`.
* Fix typos/punctuation
* Fix --trailing-comma formatting
* feat(api): add custom parser API
* test(api): add integration test for parser resolution
* chore(api): fix build after resolving conflicts
* docs(api): document custom parser API
* docs(api): fix typo
* chore(build): add parse5 to build and support yarn test --prod
* Adding --stdin-filepath option in order to enable filetype inference from
stdin
* Creating vim editor integration docs
- Moving vim editor integration into editors directory
- Adding information about vim-prettier
* Refer to "line length" instead of "line width"
- It's consistent with what it has been called in the section so far.
* Add missing punctuation
* Remove needless "just"s
- It's less condescending to a reader who doesn't know how to
"just" do these things.
* Add `formatWithCursor` API with `cursorOffset` option
This addresses https://github.com/prettier/prettier/issues/93 by
adding a new option, `cursorOffset`, that tells prettier to determine
the location of the cursor after the code has been formatted. This is
accessible through the API via a new function, `formatWithCursor`, which
returns a `{formatted: string, cursorOffset: ?number}`.
Here's a usage example:
```js
require("prettier").formatWithCursor(" 1", { cursorOffset: 2 });
// -> { formatted: '1;\n', cursorOffset: 1 }
```
* Add `--cursor-offset` CLI option
It will print out the offset instead of the formatted output. This
makes it easier to test. For example:
echo ' 1' | prettier --stdin --cursor-offset 2
# prints 1
* Add basic test of cursor translation
* Document `cursorOffset` option and `formatWithCursor()`
* Print translated cursor offset to stderr when --cursor-offset is given
This lets us continue to print the formatted code, while also
communicating the updated cursor position.
See https://github.com/prettier/prettier/pull/1637#discussion_r119735496
* doc-print cursor placeholder in comments.printComments()
See https://github.com/prettier/prettier/pull/1637#discussion_r119735149
* Compare array index to -1 instead of >= 0 to determine element presence
See https://github.com/prettier/prettier/pull/1637#discussion_r119736623
* Return {formatted, cursor} from printDocToString() instead of mutating options
See https://github.com/prettier/prettier/pull/1637#discussion_r119737354
* Adding --stdin-filepath option in order to enable filetype inference from stdin to allow chosing css parser
* Adding readme information on the filepath option
* Also including support for typescript parser inference.
* Running linter
* Move range extension code into helper functions
* Add findNodeByOffset() helper
This was adapted from cbc1929c64
* Test extending formatted range to entire node
* Fix extending formatted range to entire node
* Fix style errors
* Add run_file test function
This makes it possible to use different options on a per-file basis,
which is useful for things like range formatting tests.
* Test extending the format range to nearest parseable node
This means you can select the range of a `catch` clause, attempt to
format it, and have the `try` formatted as well, rather than throwing an
error.
* Fix extending the format range to nearest parseable node
This means you can select the range of a `catch` clause, attempt to
format it, and have the `try` formatted as well, rather than throwing an
error.
* Test that external indentation is left alone when formatting a range
* Preserve external indentation when formatting a range
* Dedupe range formatting traversal callbacks
* Simplify range formatting traversal using ast-types
See https://github.com/prettier/prettier/pull/1659#issuecomment-302974798
* Make range formatting traversal more efficient
There's less unnecessary parsing now.
* Fix style errors
* Add test where range expanding fails
* Fix test where range expanding fails
This makes sure that the range contains the entirety of the nodes
containing each of the range's endpoints.
* Add test for expanding range to beginning of line
* Pass test for expanding range to beginning of line
This makes it so that indentation before the range is added to the
formatted range.
* Don't parse/stringify AST to detect pre-range indentation
See https://github.com/prettier/prettier/pull/1659#discussion_r117790671
* When formatting a range, find closest statement rather than parsing
The `isStatement` implementation came from `docs/prettier.min.js`.
See https://github.com/prettier/prettier/pull/1659#issuecomment-303154770
* Add test for range-formatting a FunctionDeclaration's argument object
* Include FunctionDeclaration when searching for nearest node to range-format
From the spec, a Program is a series of SourceElements, each of which is
either a Statement or a FunctionDeclaration. See
https://www.ecma-international.org/ecma-262/5.1/#sec-A.5
* Remove unnecessary try-catch
See https://github.com/prettier/prettier/pull/1659#discussion_r117810096
* Add tests with multiple statements
See https://github.com/prettier/prettier/pull/1659#discussion_r117810753
* Remove unnecessary arguments from findNodeByOffset()
* Contract format range to ensure it starts/ends on nodes
* Specify test ranges in the fixtures
See https://github.com/prettier/prettier/pull/1659#discussion_r117811186
* Remove unnecessary comments from range fixtures
* Remove run_file test function
It's no longer used. This essentially reverts
8241216e68f2e0da997a4f558b03658d642c89a2
* Update range formatting docs
Clarify that the range expands to the nearest statement, and not to the
end of the line.
* Don't overwrite test options when detecting range
Now that multiple files share the same object again, we shouldn't be
re-assigning to it.
* Reuse already-read fixtures for AST_COMPARE=1 tests
* Remove `run_file` global from test eslintrc
* Undo package.json churn
`yarn` reformatted it before, but the whitespace visually sets off the
comment, so let's put it back how it was before.
See https://github.com/prettier/prettier/pull/1659#discussion_r117864655
* Remove misleading comments from isSourceElement
See https://github.com/prettier/prettier/pull/1659#discussion_r117865196
* Loop backwards through string instead of reversing it
See https://github.com/prettier/prettier/pull/1659#discussion_r117865759
* Don't recompute indent string when formatting range
See https://github.com/prettier/prettier/pull/1659#discussion_r117867268
* Rename findNodeByOffset to findNodeAtOffset
"Find x by y" is the common usage for finding an `x` by a key `y`.
However, since "by" has positional meaning, let's use "at" instead.
See https://github.com/prettier/prettier/pull/1659#discussion_r117865121
* Always trimRight() in formatRange and explain why
See https://github.com/prettier/prettier/pull/1659#discussion_r117864635
* Test formatting a range that crosses AST levels
See https://github.com/prettier/prettier/pull/1659#issuecomment-303243688
* Fix formatting a range that crosses AST levels
See https://github.com/prettier/prettier/pull/1659#issuecomment-303243688
* Remove unnecessary try-catch
See e52db5e9f9 (r117878763)
* Add test demonstrating range formatting indent detection
* Detect alignment from text on line before range, but don't reformat it
This avoids reformatting non-indentation that happens to precede the
range on the same line, while still correctly indenting the range based
on it.
See https://github.com/prettier/prettier/pull/1659#discussion_r117881430
* Improve ESLint setup
- Uses `eslint:recommended` + a handful more rules.
- Uses .eslintignore so that editors can understand which files to lint.
- Uses .eslintrc<strong>.js</strong> so more editors get syntax highlighting.
* Fix ESLint errors
About half of them were fixed by `eslint . --fix`.
