Hacker News users discuss XAN's potential, particularly its speed and ease of use for data manipulation tasks compared to traditional tools like
awkandsed. Some express excitement about its CSV parsing capabilities and the ability to leverage Python's power. Concerns are raised regarding the dependency on Python, potential performance bottlenecks, and the limited feature set compared to more established data wrangling tools like Pandas. The discussion also touches upon the project's early stage of development, with some users interested in contributing and others suggesting potential improvements like better documentation and integration with other command-line tools. Several comments compare XAN favorably to other similar tools likejqandmiller, emphasizing its niche in CSV manipulation.The Hacker News post titled "XAN: A Modern CSV-Centric Data Manipulation Toolkit for the Terminal" (https://news.ycombinator.com/item?id=43494894) has generated several comments discussing the merits and potential drawbacks of the XAN tool.
Several commenters express enthusiasm for XAN, praising its seemingly intuitive syntax and potential for simplifying common data manipulation tasks. One commenter highlights the apparent ease of use, suggesting it could be a more accessible alternative to more complex command-line tools like
awkorjq. Another appreciates its CSV-centric approach, noting that CSV is a ubiquitous format and a tool specifically designed for it could be quite useful. The ability to perform calculations and filtering within XAN is also mentioned as a positive feature.However, other comments raise concerns and offer alternative perspectives. Some users question the need for another specialized tool when existing solutions like
awk,jq, Miller,xsv, and Python'spandaslibrary already provide similar functionality. They argue that learning yet another tool might not be worthwhile, especially if the existing tools can accomplish the same tasks with comparable or even greater flexibility. The "not invented here" syndrome is also mentioned in this context.One commenter specifically mentions the power and versatility of
jq, emphasizing its ability to handle various data formats beyond CSV, including JSON, and its extensive feature set. They suggest thatjqmight be a more robust solution for those working with diverse data types.Another point of discussion revolves around the choice of Rust as the implementation language for XAN. While some applaud the use of Rust for its performance characteristics, others question whether its complexity might make contributing to the project more challenging. There's also a brief discussion about the potential overhead associated with Rust and whether it's significant enough to outweigh its benefits in this specific use case.
Finally, some commenters express interest in trying out XAN and exploring its capabilities firsthand, while others remain skeptical but acknowledge its potential. The overall sentiment seems to be one of cautious curiosity, with some users excited about the prospect of a new CSV-centric tool but others remaining unconvinced of its necessity given the existing alternatives.
