About livegrep

Livegrep is a tool, partially inspired by Google Code Search, for interactive regex search of ~gigabyte-scale source repositories. To run livegrep, you need to invoke both the codesearch backend index/search process, and the livegrep web interface. To run the sample web interface over livegrep itself, once you have built both codesearch and livegrep. The codesearch binary is responsible for reading source code, maintaining an index, and handling searches. livegrep is stateless and relies only on the connection to codesearch over a TCP connection. By default, codesearch will build an in-memory index over the repositories specified in its configuration file. You can, however, also instruct it to save the index to a file on disk. This has the dual advantages of allowing indexes that are too large to fit in RAM, and of allowing an index file to be reused.

Hound

Hound is an extremely fast source code search engine. The core is based on this article (and code) from Russ Cox: Regular expression matching with a trigram index. Hound itself is a static React frontend that talks to a Go backend. The backend keeps an up-to-date index for each repository and answers searches through a minimal API. Currently Hound is only tested on MacOS and CentOS, but it should work on any *nix system. Hound on Windows is not supported but we've heard it compiles and runs just fine (although it helps to to exclude your data folder from Windows Search Indexer).

Sourcetrail

Sourcetrail is an interactive source explorer that simplifies navigation in existing source code by indexing your code and gathering data about its structure. Sourcetrail then provides a simple interface consisting of three interactive views, each playing a key role in helping you obtain the information you need. Search: Use the search field to quickly find and select indexed symbols in your source code. The autocompletion box will instantly provide an overview of all matching results throughout your codebase. Graph: The graph displays the structure of your source code. It focuses on the currently selected symbol and directly shows all incoming and outgoing dependencies to other symbols. Code: The Code view displays all source locations of the currently selected symbol in a list of code snippets. Clicking on a different source location allows you to change the selection and dig deeper.
