Possible disadvantages of regular expressions 101

  • Limited to Browser
    Regex101 is a web-based tool, and its usage is restricted to browsers with internet access, limiting its offline availability and performance in a development environment.
  • User Interface Complexity
    For beginners, the user interface can be somewhat overwhelming due to the numerous options and features available, leading to a steeper learning curve.
  • Performance Limitations
    While sufficient for most use cases, Regex101 may struggle with very large datasets or extremely complex regular expressions, causing performance issues.
  • Dependency on External Product
    Relying on an external service means users are dependent on the platform's availability and continued maintenance, which can be a risk if the service goes down or changes significantly.
  • Potential Overreliance
    Frequent use of Regex101 for developing regular expressions may lead to an overreliance on the tool, potentially hindering the development of strong, intrinsic regex skills.

Possible disadvantages of grep.app

  • Limited Scope
    grep.app focuses primarily on code repositories, which may not be useful for individuals seeking to search non-code content or specific file types outside its scope.
  • Internet Dependency
    The platform requires an internet connection to access its search features, which might be a limitation for users in areas with unstable internet connectivity.
  • Privacy Concerns
    As with any online search tool, there may be concerns regarding the privacy of search queries and how they are stored or used by the service.
  • Learning Curve
    While generally user-friendly, some users may experience a learning curve in leveraging advanced search functions without prior experience or documentation.
  • Resource Intensity
    Executing large or complex searches can be resource-intensive, potentially slowing down performance for larger queries or datasets.

  • Regex Isn't Hard (2023)
    In practice, the first unpaired ] is treated as an ordinary character (at least according to https://regex101.com/) - which does nothing to make this regex fit for its intended purpose. I'm not sure whether this is according to spec. (I think it is, though that does not really matter compared to what the implementations actually do.) Characters which are sometimes special, depending on context, are one more thing... - Source: Hacker News / about 1 month ago

  • Ask HN: Little or even unknown website that you like to use?
    Https://grep.app - To search repos for patterns. I usually use it when I'm using an obscure or badly documented library. https://unicode.scarfboy.com/ - Unicode stuff. There are a lot of small Unicode tool sites. - Source: Hacker News / 3 months ago
  • Nginx Has Moved to GitHub
    There are some alternatives like https://grep.app or https://sourcegraph.com/search if you want fast live search, but at the end of the day these are generally expensive services to provide, especially for free anonymous users, so you should probably at least accept that service providers can and do change things like this. You can also run something like your own copy of Zoekt and then ingest repositories on... - Source: Hacker News / 9 months ago
  • Sourcegraph Went Dark
    Https://grep.app/ is another good one. Not sure how many repos they index though. - Source: Hacker News / 9 months ago
  • Code Finder – The ultimate search engine for GitHub repositories
    Https://grep.app/ is similar and seems to return results, but I have not compared it to native GitHub search. - Source: Hacker News / 12 months ago
  • Ask HN: Grep.app Alternative?
    Https://grep.app/ has served me well for the last couple of years finding snippets for random APIs. But recently I found that certain strings from open-source projects suddenly yield no results. For example: VaultServiceTimeout from https://github.com/rajanadar/VaultSharp has no results for https://grep.app/search?q=VaultServiceTimeout. Is there some alternative service for this task that is up-to-date? - Source: Hacker News / about 1 year ago
