Involve regular expressions to solve different kind of tasks regarding text content
Let me introduce a nodejs library called regexp-it-cli.
I am going to demonstrate some use cases where this tool would be applicable.
Regexp playground
You can experiment with regular expression by passing some content as a source and executing your trial regular over it. For example, display only matched parts for specified regexp:
Show some content in slide mode
Have you ever wanted a find functionality without dealing with manually movement handling to the next match but automatically see the next matches with some interval? Slide mode to the rescue! Use the –slide-mode option optionally providing also –slide-delay specifying a delay in seconds you’d like:
Filtering content between sections
You can use regexp in a source only after/before specified –after-regexp and –before-regexp:
Displaying first and last match
Display only first/last match by providing the –only-first-match / –only-last-match flag
Specify starting/ending line from a source to be used as a content
Apply filter to content that is going to be used a source for a regular expression by using the –starting-line-number, –ending-line-number options.
