A stupid simple, powerful source code analyzer, targeting help you understand codebase as quickly as possible.
- Count lines of code, total files, and ranking of folders based on including lines of code.
Dive-into-source owns high performance, See Benchmark for the performance compared with other similar tools.
- Generate calling-graph between all functions or methods
- Generate dataStructure-definitions-graph of all codebase modules
- Parse repo git data.
- Full-text fuzzy search in code.
To try dive-into-source, your system should have Node.js installed,
View Node.js Downloads for more details.
npm install -g dive-into-sourceor with yarn:
yarn global add dive-into-sourceOnce installed, there should be a executable binary file called divesource existed
in your npm bin directory, just execute it:
divesource [codebase]If codebase parameter omitted, the current directory will become the codebase.
There are many options to config behaviour of divesource, just type:
divesource -hto view all of them.
Motivated by cloc, a tool to count lines of code of a repo.
Being a software or hardware engineer, most of our carrer time will spend on reading source code of others, maby be 80 percent or 90 percent.
When i view linux kernel source code, it's too hard to understand kernel which has more than 18 million lines of code.
So i searched with google, willing to find a better tool to help me. sadly, existing tools either bad or just expensive,
Besides, all of them have bad UI and being very complex, that's why dive-into-source came out!
- Fully extensible. you can write your own language to be accepted by dive-into-source. Besides, you can even write your own analyze feature.
- dive-into-source: All in one library to start with the project
- dive-into-source-engine: The engine library to analyze source code
- dive-into-source-visual: The default visual website to render generated data by engine
Cloc feature benchmark:
- Intel® Core™ i5-11600K / 16G Mem / Ubuntu 21.04
- tokei: version 12.1.2, written in Rust.
- cloc: version 1.86, written in Perl.
- gocloc: version v0.4.1, written in Go.
- dive-into-source: version 0.1.4, written in Node.js.
- Target codebase: kubernetes/kubernetes, commit: 08bf54678e2, which has 104458 commits and 23398 files.
