How to format logs, scripts, configs and general console output

Site Feedback and Other Questions
1

In the OpenWrt forum, you oftentimes need to post excerpts of logfiles, configs, shell scripts or other general console output. In order to improve readabilty, please use the "Preformatted text </>" button in the editor bar for such text.

Why?

  • If you just paste this stuff to your posting without applying the proper formatting, the result will probably look awfull (see examples below).
  • If you do apply the proper formatting, the result will probably look much better than without, since (fixed width dependant) aligned structures are preserved (see examples below). This will make it much easier for other forum users to read, understand, and reply to your message.
  • Preformatted text is especially good for pasting longer amounts of build logs or other lengthy stuff: not only do you get a fixed-width / non-proportional font for free, you also avoid having to scroll the whole thread over pages, but have the content boxed in with its own scroll bars and limited to a workable size.

How?

Use it the same way as you would use the bold or italic formatting, i.e.

  1. Mark the text that you want to format
  2. Click the "Preformatted text </>" button in the editor bar
