The Code Text Splitter is a specialized text splitter designed to split documents based on language-specific syntax. It utilizes the RecursiveCharacterTextSplitter
from the LangChain library to perform intelligent splitting of code documents.
Name: codeTextSplitter
Type: CodeTextSplitter
Version: 1.0
Category: Text Splitters
Type: Options
Description: The programming language of the code to be split.
Options:
cpp
go
java
js
php
proto
python
rst
ruby
rust
scala
swift
markdown
latex

sol
Type: Number
Default: 1000
Optional: Yes
Description: The number of characters in each chunk. This determines the size of the text segments after splitting.
Type: Number
Default: 200
Optional: Yes
Description: The number of characters to overlap between chunks. This helps maintain context between split segments.
The node expects code or text input in the specified language.
The node outputs split text chunks based on the specified parameters and language-specific syntax.
This node is particularly useful in workflows that involve processing or analyzing code, such as:
Code summarization
Code analysis tasks
Preparing code for language models
Splitting large codebases for easier processing
By respecting the syntax of the chosen programming language, it ensures that the splitting process maintains the logical structure of the code as much as possible, which can lead to better results in downstream tasks.
The node uses the RecursiveCharacterTextSplitter.fromLanguage()
method from LangChain, which applies language-specific splitting rules. This method is more intelligent than a simple character-based split, as it attempts to split at appropriate syntactic boundaries for the given language.
The effectiveness of the splitting can vary depending on the complexity and structure of the input code. Users may need to experiment with different chunk sizes and overlaps to achieve optimal results for their specific use case.
