ifc-language-server/node_modules/@stylistic/eslint-plugin/dist/rules/indent.js
Ryan Schultz 8afacf268a Implemented a working Language Server Protocol (LSP) for IFC files with:
- Hover provider showing entity information and type
- Go-to-definition (F12) for entity references
- Basic IFC file validation (ISO-10303-21 header check)
- Entity parsing with regex-based detection
- Proper CommonJS module system (avoiding ES module issues)

This replaces the broken baseline from ifc-developer-tools which had:
- Non-functional ES module configuration
- Circular dependency issues
- Parser crashes
- Non-working PositionVisitor

Built on Microsoft's LSP example template for a clean, maintainable foundation.

Next: Add hierarchical entity dependency tree in hover tooltip."

/**
* Sets the desired offset of a token.
*
* This uses a line-based offset collapsing behavior to handle tokens on the same line.
* For example, consider the following two cases:
*
* (
* [
* bar
* ]
* )
*
* ([
* bar
* ])
*
* Based on the first case, it's clear that the `bar` token needs to have an offset of 1 indent level (4 spaces) from
* the `[` token, and the `[` token has to have an offset of 1 indent level from the `(` token. Since the `(` token is
* the first on its line (with an indent of 0 spaces), the `bar` token needs to be offset by 2 indent levels (8 spaces)
* from the start of its line.
*
* However, in the second case `bar` should only be indented by 4 spaces. This is because the offset of 1 indent level
* between the `(` and the `[` tokens gets "collapsed" because the two tokens are on the same line. As a result, the
* `(` token is mapped to the `[` token with an offset of 0, and the rule correctly decides that `bar` should be indented
* by 1 indent level from the start of the line.
*
* This is useful because rule listeners can usually just call `setDesiredOffset` for all the tokens in the node,
* without needing to check which lines those tokens are on.
*
* Note that since collapsing only occurs when two tokens are on the same line, there are a few cases where non-intuitive
* behavior can occur. For example, consider the following cases:
*
* foo(
* ).
* bar(
* baz
* )
*
* foo(
* ).bar(
* baz
* )
*
* Based on the first example, it would seem that `bar` should be offset by 1 indent level from `foo`, and `baz`
* should be offset by 1 indent level from `bar`. However, this is not correct, because it would result in `baz`
* being indented by 2 indent levels in the second case (since `foo`, `bar`, and `baz` are all on separate lines, no
* collapsing would occur).
*
* Instead, the correct way would be to offset `baz` by 1 level from `bar`, offset `bar` by 1 level from the `)`, and
* offset the `)` by 0 levels from `foo`. This ensures that the offset between `bar` and the `)` are correctly collapsed
* in the second case.
* @param token The token
* @param fromToken The token that `token` should be offset from
* @param offset The desired indent level

/**
* Sets the desired offset of all tokens in a range
* It's common for node listeners in this file to need to apply the same offset to a large, contiguous range of tokens.
* Moreover, the offset of any given token is usually updated multiple times (roughly once for each node that contains
* it). This means that the offset of each token is updated O(AST depth) times.
* It would not be performant to store and update the offsets for each token independently, because the rule would end
* up having a time complexity of O(number of tokens * AST depth), which is quite slow for large files.
*
* Instead, the offset tree is represented as a collection of contiguous offset ranges in a file. For example, the following
* list could represent the state of the offset tree at a given point:
*
* - Tokens starting in the interval [0, 15) are aligned with the beginning of the file
* - Tokens starting in the interval [15, 30) are offset by 1 indent level from the `bar` token
* - Tokens starting in the interval [30, 43) are offset by 1 indent level from the `foo` token
* - Tokens starting in the interval [43, 820) are offset by 2 indent levels from the `bar` token
* - Tokens starting in the interval [820, ∞) are offset by 1 indent level from the `baz` token
*
* The `setDesiredOffsets` methods inserts ranges like the ones above. The third line above would be inserted by using:
* `setDesiredOffsets([30, 43], fooToken, 1);`
* @param range A [start, end] pair. All tokens with range[0] <= token.start < range[1] will have the offset applied.
* @param fromToken The token that this is offset from
* @param offset The desired indent level
* @param force `true` if this offset should not use the normal collapsing behavior. This should almost always be false.
