I'm using the plan9port version of acme, and I typically run in autoindent mode, which seems to trigger this behavior. >From the man page: > When a window is in autoindent mode [...] and a newline character is > typed, acme copies leading white space on the current line to the new > line, and when a window is Put, acme removes all trailing end-of-line > white space before writing the file.

As noted earlier, the shebang just determines which shell the script will run in; you can choose any shell, or use any executable. You'll just want to make sure that the script is in your $PATH. For example, you could create this as $HOME/bin/lstrip: #! /bin/sh ssam 'x/^ +?/d' Make it executable, then write some text in acme: This is some text that will be cleaned If you select this text, type "|lstrip" in the tag (without the quotes), and Button-2 (middle click) it, you will get the desired effect: This is some text that will be cleaned To operate on the entire window, type "Edit ,|lstrip" and execute that with B2. By the way, as for your other example of cleaning whitespace at the end of a newline (Edit ,x/ +$/d), acme does this by default on Put. The other way you might approach this is just to keep a text file of commonly used commands around. Then you can select the command you want, and mouse-chord B2-B1 on "Edit" in the tag of the desired window to execute that command. - Ben -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Taf408751bc6fb344-Mab8c70f37dc76a709197b202 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

Re: [9fans] Script to apply Edit commands in acme
You can, of course, execute multiple commands in one Edit, either lineline
or chroding the "{}" block:
Edit {
,x/a/c/b/
,x/d/c/e/
}

Re: [9fans] Script to apply Edit commands in acme
Here is a script I wrote to run any arbitrary command (Edit, Look, etc) in a window (current one by default): https://gist.github.com/perpen/9902359ddf09b24129277ce121e3e86d E.g.: Aexe 'Edit ,blah' It's quite horrible, as it appends the command to the body to run it using an event (would have been simpler running the command from the tag, but there is race making that impossible iirc). I ended up not using it, so it is not much tested. And I wrote it for plan 9, not sure how that would work with plan9port. On Mon, Jan 16, 2023 at 9:06 AM wrote: > > Great tips. Thank you.

Re: [9fans] Script to apply Edit commands in acme
Hello, the shebang (#!/bin/rc) just says which shell you want to run it. You could also use /bin/ed, if you want to run ed commands, for example. Acme can do pretty crazy stuff to extend it. For example, you can write your own scripts (or programs) in any language you like. Middle-click can execute simple programs with no magic. See also /acme/ folder for examples. There can be simple programs like spell checkers that are just scripts using the file path as parameters, and there are more complex programs that actually use the acme filesystem to do crazy stuff. For example, you can adjust the buffer as you like, write into the tag line whatever you like, capture mouse input in the tag line and do whatever you like, oben new acme windows, For your specific question about Edit commands, I don't know of a way. However, if there is a way I'm sure you can find it in the man pages. What could work though, is running ssam (or sam) on the data file in your acme filesystem. It just exposes an interface for each of your acme windows with a few files to control it. sirjofri -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Taf408751bc6fb344-M75bfff0a46aceb39fb2713c0 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
