TreeLayout creates tree layouts for arbitrary trees. It is not restricted to a specific output or format, but can be used for any kind of two dimensional diagram. Examples are Swing based components, SVG files, etc. This is possible because TreeLayout separates the layout of a tree from the actual rendering.

Algorithms for detecting population structure from the history of coalescent events recorded in phylogenetic trees. This method classifies each tip and internal node of a tree into disjoint sets characterized by similar coalescent patterns. The methods are described in Volz, E., Wiuf, C., Grad, Y., Frost, S., Dennis, A., & Didelot, X. (2020) <doi:10.1093/sysbio/syaa009>.

This data structure can be used to store the history of visited paths or URLs with a file or web browser, in a way that no “forward” element is ever forgotten.

The history tree is “global” in the sense that multiple owners (e.g. tabs) can have overlapping histories. On top of that, an owner can spawn another one, starting from one of its nodes (typically when you open a URL in a new tab).

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited.

Tree-sitter aims to be:

1. General enough to parse any programming language.

2. Fast enough to parse on every keystroke in a text editor.

3. Robust enough to provide useful results even in the presence of syntax errors.

4. Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application.

This package includes the tree-sitter command-line tool.
