7695 :: Can I do text replacements in a file via a NimScript?

• halloleo (orginal) [2021-03-24T06:58:54+01:00] view original

  I need to do as part of a build step some string replacements in a text file.

  In full Nim I'm able to do this via stream reading, text replacements, and stream writing - can I do this in NimScript (i.e. config.nims) as well? The streams module is not listed for NimScript...

  Thanks for any pointers!

  i think the answer is no, nimscript can't do file io, so you'll need to exec something to do the work for you, maybe sed, patch, or a utility you write yourself

  The utility to use is nimgrep ;-)

  Thanks @shirleyquirk. I thought so, just wanted to doublecheck whether I had missed something.

  Cool. nimgrep looks pretty good for Nim files! :-)

  The doco mentions briefly support for PEGs, but how do I provide them here?
