/* Very simple logger interface.
|
||
|
||
Each module is expected to create its own logger by doing e.g.:
|
||
|
||
const logger = getLogger('my-prefix');
|
||
|
||
and then use it instead of console:
|
||
|
||
logger.info('hello', 'world');
|
||
logger.warn('...');
|
||
logger.error('...');
|
||
|
||
The logger automatically adds the prefix "[my-prefix]" to all logs; so e.g., the
|
||
above call would print:
|
||
|
||
[my-prefix] hello world
|
||
|
||
logger.log is intentionally omitted. The idea is that PyScript should not
|
||
write anything to console.log, to leave it free for the user.
|
||
|
||
Currently, the logger does not to anything more than that. In the future,
|
||
we might want to add additional features such as the ability to
|
||
enable/disable logs on a global or per-module basis.

// A style is an object that, in the simple case, maps CSS property
|
||
// names to strings holding their values, as in `{color: "red",
|
||
// fontWeight: "bold"}`. The property names can be given in
|
||
// camel-case—the library will insert a dash before capital letters
|
||
// when converting them to CSS.
|
||
//
|
||
// If you include an underscore in a property name, it and everything
|
||
// after it will be removed from the output, which can be useful when
|
||
// providing a property multiple times, for browser compatibility
|
||
// reasons.
|
||
//
|
||
// A property in a style object can also be a sub-selector, which
|
||
// extends the current context to add a pseudo-selector or a child
|
||
// selector. Such a property should contain a `&` character, which
|
||
// will be replaced by the current selector. For example `{"&:before":
|
||
// {content: '"hi"'}}`. Sub-selectors and regular properties can
|
||
// freely be mixed in a given object. Any property containing a `&` is
|
||
// assumed to be a sub-selector.
|
||
//
|
||
// Finally, a property can specify an @-block to be wrapped around the
|
||
// styles defined inside the object that's the property's value. For
|
||
// example to create a media query you can do `{"@media screen and
|
||
// (min-width: 400px)": {...}}`.

cursors with elements overlaid over the code (using

|

This allows the editor to display secondary selection ranges, and

tends to produce a type of selection more in line with that users

expect in a text editor (the native selection styling will often

leave gaps between lines and won't fill the horizontal space after
|

a line when the selection continues past it).
|
||
|
||
It does have a performance cost, in that it requires an extra DOM
|

layout cycle for many updates (the selection is drawn based on DOM
|

layout information that's only available after laying out the

content).

This function is used to add a set of tags to a language syntax

|
||
|
||
The argument object maps node selectors to [highlighting
|
||
tags](https://codemirror.net/6/docs/ref/#highlight.Tag) or arrays of tags.
|
||
|
||
Node selectors may hold one or more (space-separated) node paths.
|
||
Such a path can be a [node
|
||
name](https://lezer.codemirror.net/docs/ref#common.NodeType.name),
|
||
or multiple node names (or `*` wildcards) separated by slash
|
||
characters, as in `"Block/Declaration/VariableName"`. Such a path
|
||
matches the final node but only if its direct parent nodes are the
|
||
other nodes mentioned. A `*` in such a path matches any parent,
|
||
but only a single level—wildcards that match multiple parents
|
||
aren't supported, both for efficiency reasons and because Lezer
|
||
trees make it rather hard to reason about what they would match.)
|
||
|
||
A path can be ended with `/...` to indicate that the tag assigned
|
||
to the node should also apply to all child nodes, even if they
|
||
match their own style (by default, only the innermost style is
|
||
used).
|
||
|
||
When a path ends in `!`, as in `Attribute!`, no further matching
|
||
happens for the node's child nodes, and the entire node gets the
|
||
given style.
|
||
|
||
In this notation, node names that contain `/`, `!`, `*`, or `...`
|
||
must be quoted as JSON strings.
|
||
|
||
For example:
|
||
|
||
```javascript
|
||
parser.withProps(
|
||
styleTags({
|
||
// Style Number and BigNumber nodes
|
||
"Number BigNumber": tags.number,
|
||
// Style Escape nodes whose parent is String
|
||
"String/Escape": tags.escape,
|
||
// Style anything inside Attributes nodes
|
||
"Attributes!": tags.meta,
|
||
// Add a style to all content inside Italic nodes
|
||
"Italic/...": tags.emphasis,
|
||
// Style InvalidString nodes as both `string` and `invalid`
|
||
"InvalidString": [tags.string, tags.invalid],
|
||
// Style the node named "/" as punctuation
|
||
'"/"': tags.punctuation

||
})

/**
|
||
The default set of highlighting [tags](https://codemirror.net/6/docs/ref/#highlight.Tag^define) used
|
||
by regular language packages and themes.
|
||
|
||
This collection is heavily biased towards programming languages,
|
||
and necessarily incomplete. A full ontology of syntactic
|
||
constructs would fill a stack of books, and be impractical to
|
||
write themes for. So try to make do with this set. If all else
|
||
fails, [open an
|
||
issue](https://github.com/codemirror/codemirror.next) to propose a
|
||
new tag, or [define](https://codemirror.net/6/docs/ref/#highlight.Tag^define) a local custom tag for
|
||
your use case.
|
||
|
||
Note that it is not obligatory to always attach the most specific
|
||
tag possible to an element—if your grammar can't easily
|
||
distinguish a certain type of element (such as a local variable),
|
||
it is okay to style it as its more general variant (a variable).
|
||
|
||
For tags that extend some parent tag, the documentation links to
|
||
the parent.

/**
|
||
This is an extension value that just pulls together a whole lot of
|
||
extensions that you might want in a basic editor. It is meant as a
|
||
convenient helper to quickly set up CodeMirror without installing
|
||
and importing a lot of packages.
|
||
|
||
Specifically, it includes...
|
||
|
||
- [the default command bindings](https://codemirror.net/6/docs/ref/#commands.defaultKeymap)
|
||
- [line numbers](https://codemirror.net/6/docs/ref/#gutter.lineNumbers)
|
||
- [special character highlighting](https://codemirror.net/6/docs/ref/#view.highlightSpecialChars)
|
||
- [the undo history](https://codemirror.net/6/docs/ref/#history.history)
|
||
- [a fold gutter](https://codemirror.net/6/docs/ref/#fold.foldGutter)
|
||
- [custom selection drawing](https://codemirror.net/6/docs/ref/#view.drawSelection)
|
||
- [drop cursor](https://codemirror.net/6/docs/ref/#view.dropCursor)
|
||
- [multiple selections](https://codemirror.net/6/docs/ref/#state.EditorState^allowMultipleSelections)
|
||
- [reindentation on input](https://codemirror.net/6/docs/ref/#language.indentOnInput)
|
||
- [the default highlight style](https://codemirror.net/6/docs/ref/#highlight.defaultHighlightStyle) (as fallback)
|
||
- [bracket matching](https://codemirror.net/6/docs/ref/#matchbrackets.bracketMatching)
|
||
- [bracket closing](https://codemirror.net/6/docs/ref/#closebrackets.closeBrackets)
|
||
- [autocompletion](https://codemirror.net/6/docs/ref/#autocomplete.autocompletion)
|
||
- [rectangular selection](https://codemirror.net/6/docs/ref/#rectangular-selection.rectangularSelection) and [crosshair cursor](https://codemirror.net/6/docs/ref/#rectangular-selection.crosshairCursor)
|
||
- [active line highlighting](https://codemirror.net/6/docs/ref/#view.highlightActiveLine)
|
||
- [active line gutter highlighting](https://codemirror.net/6/docs/ref/#gutter.highlightActiveLineGutter)
|
||
- [selection match highlighting](https://codemirror.net/6/docs/ref/#search.highlightSelectionMatches)
|
||
- [search](https://codemirror.net/6/docs/ref/#search.searchKeymap)
|
||
- [commenting](https://codemirror.net/6/docs/ref/#comment.commentKeymap)
|
||
- [linting](https://codemirror.net/6/docs/ref/#lint.lintKeymap)
|
||
|
||
(You'll probably want to add some language package to your setup
|
||
too.)
|
||
|
||
This package does not allow customization. The idea is that, once
|
||
you decide you want to configure your editor more precisely, you
|
||
take this package's source (which is just a bunch of imports and
|
||
an array literal), copy it into your own code, and adjust it as
|
||
desired.
