srclib Build Status

Note: srclib is alpha. Post an issue if you have any questions or difficulties running and hacking on it.

srclib is a source code analysis library. It provides standardized tools, interfaces and data formats for generating, representing and querying information about source code in software projects.

Why? Right now, most people write code in editors that don't give them as much programming assistance as is possible. That's because creating an editor plugin and language analyzer for your favorite language and editor combo is a lot of work. And when you're done, your plugin only supports a single language and editor, and maybe only half the features you wanted (such as doc lookups and "find usages"). Because there are no standard cross-language and cross-editor APIs and formats, it is difficult to reuse your plugin for other languages or editors.

We call this the M-by-N problem: given M editors and N languages, we need to write (on the order of) M×N plugins to get good tooling in every case. That number gets large quickly, and it's why we suffer from poor developer tools.

srclib solves this problem in 2 ways by:

  • Publishing standard formats and APIs for source analyzers and editor plugins to use. This means that improvements in a srclib language analyzer benefit users in any editor, and improvements in a srclib editor plugin benefit everyone who uses that editor on any language.

  • Providing high-quality language analyzers and editor plugins that implement this standard. These were open-sourced from the code that powers Sourcegraph.com.

See srclib.org for more information.

Currently, srclib supports:

Want to extend srclib to support more languages, features, or editors? During this alpha period, we will work closely with you to help you. Post an issue to let us know what you're building to get started.

Usage

See Getting started for installation instructions.

Once you install srclib's src tool and language support toolchains, you'll use srclib by installing an editor plugin in your editor of choice. See all editor plugins.

Misc.

  • bash completion for src: run source contrib/completion/src-completion.bash or copy that file to /etc/bash_completion.d/srclib_src (path may be different on your system)

Variables

var (
	// Path is SRCLIBPATH, a colon-separated list of directories that lists
	// places to look for srclib toolchains and cache build data. It is
	// initialized from the SRCLIBPATH environment variable; if empty, it
	// defaults to $HOME/.srclib.
	Path = os.Getenv("SRCLIBPATH")

	// CacheDir stores cached build results. It is initialized from the
	// SRCLIBCACHE environment variable; if empty, it defaults to DIR/.cache,
	// where DIR is the first entry in Path (SRCLIBPATH).

Types

type ToolRef

type ToolRef struct {
	// Toolchain is the toolchain path of the toolchain that contains this tool.
	Toolchain string

	// Subcmd is the name of the toolchain subcommand that runs this tool.
	Subcmd string
}

A ToolRef identifies a tool inside a specific toolchain. It can be used to look up the tool.

func (ToolRef) MarshalFlag

func (t ToolRef) MarshalFlag() (string, error)

func (ToolRef) String

func (t ToolRef) String() string

func (*ToolRef) UnmarshalFlag

func (t *ToolRef) UnmarshalFlag(value string) error
