Have you run epm:upgrade? This is fixed already since a few days ago.

I did plot most recent on the left, and that jump was on commit elves/elvish@70cb56b

when I get a chance I'll try and test if with the commits under that branch, just to see if I can pinpoint the exact moment

Kurtis Rader

@krader1961:matrix.org

You probably won't be able to meaningfully test each individual commit included in the merge. The bulk of the commit is reorganizing the code to allow building an elvish binary with no support for the interactive daemon. What's interesting is that I would not expect that to affect the performance of a non-interactive session. Someone will probably need to profile the code before and after that commit to identify where the extra time is being spent.

is it possible to combine 2 or more maps into a new one?

I don’t think there’s a builtin for that yet, unfortunately

If you haven’t moved your modules they probably still live in ~/.elvish/lib which is no longer managed by epm

I've run into this issue quite a few times now and I'm getting tired of switching shells just run find with the -exec option 😅. Let's say I have this find command:

find 'Anita Lane/' -name "*.flac" -exec ffmpeg -i {} -ab 320k -map_metadata 0 -id3v2_version 3 -write_id3v1 1 ../../ipod/rerun/{}.mp3 \;

How would I get this to work in elvish? The {}s are a "special feature" of the shell it seems so find complains that there is a "missing argument to `-exec'".

You need to quote both the {} and the \;

Kurtis Rader

@krader1961:matrix.org

To clarify xiaq's answer the braces create a lambda. See the discussion of metacharacters: https://elv.sh/ref/language.html#metacharacters. Also, the description of functions: https://elv.sh/ref/language.html#fn. Too, in Elvish a backslash does not act to escape the special meaning of the next character. Simply quote special chars; so ';' rather than \;.

uver

@uver:matrix.org

Do you have to quote each individual { and } or can you do both together? I already tried '{}' but it gave the same error. I'll try again and actually quote the ; this time instead of just adding a backslash in front.

Kurtis Rader

@krader1961:matrix.org

Try it: echo a '{}' b ';

And compare that output to this: echo a {} b ;

Hello

Kurtis Rader

@krader1961:matrix.org

Welcome. You're a new Elvish shell user?

xiaqqaix (Telegram)

@telegram_84517825:elv.sh

The {} doesn’t create a lambda; a lambda requires whitespace after the opening {. It creates a braced list with no elements (https://elv.sh/ref/language.html#braced-list) which is special-cased to evaluate to an empty string

uver

@uver:matrix.org

Ok thank you both! Got it working. The issue was me not quoting the ending semicolon. I figured I needed to escape the {}s but when that didn't work, I was at a bit of a loss.

Anyone know what the preferred method for security disclosures is for this project?

Adam

@adamfontenot:matrix.org

I do have to run but if someone could @ me with an appropriate contact method, that would be great. I don't see a security email specified on the site anywhere, so I'm trying here. I'll check back sometime in the next day.

@zzamboni in the notifier is there a way to know if the process failed? I'd like it to say something out loud if the command failed

Kurtis Rader

@krader1961:matrix.org

dcuadrado (Telegram): Pretty sure zzamboni (Telegram) would appreciate a pull-request to implement that enhancement, or at least an issue to remind him that it needs to be done.

dcuadrado (Telegram)

@telegram_89056592:elv.sh

that sounds very interesting

Kurtis Rader

@krader1961:matrix.org

See elves/elvish#1029 for the impetus to implement the core feature that allows capturing that information.

Kurtis Rader

@krader1961:matrix.org

dcuadrado (Telegram): I opened zzamboni/elvish-modules#21. Comment there if I did not fully capture your requirements or you intend to make the necessary changes.

Hi guys

Hi

Johann Og

@kronolynx

HI, I would like to use vi style bindings, I found this issue elves/elvish#728 and the suggestion is to use

use binding
binding:install
edit:insert:binding["Ctrl-["] = $edit:command:start~

but when I add that to my config I get:

Exception: no such module: binding
/home/krono/.elvish/rc.elv, line 56: use binding

Any suggestions ?

See my previous reply in https://github.com/elves/elvish/issues/728#issuecomment-409375352

@kronolynx

thanks, if I use

use binding
edit:insert:binding["Ctrl-["] = $edit:command:start~

then I get the error:

Exception: no such module: binding
/home/krono/.elvish/rc.elv, line 56: use binding

if I add only this line

edit:insert:binding["Ctrl-["] = $edit:command:start~

vim keybindings are not enabled

xiaqqaix (Telegram)

@telegram_84517825:elv.sh

You need to press ESC to enter vi command mode, did you do that?

The vi command mode is very incomplete as I mentioned in the comment so it's probably not worth bothering anyway

Johann Og

@kronolynx

Thanks

Kurtis Rader

@krader1961:matrix.org

Kronolynx (Telegram): I recommend leaving the default emacs bindings in place. For non-trivial editing of the command line it's easy to drop into a real vi editor. I have this in my rc.elv:

# Arrange for [alt-e] and [alt-v] to edit the current command buffer using my
# prefered external editor.
edit:insert:binding[Alt-e] = $interactive:external_edit_command~
edit:insert:binding[Alt-v] = $interactive:external_edit_command~

Also use interactive which loads my lib/interactive.elv module that contains this:

fn external_edit_command {
  temp-file = (path:temp-file)
  print $edit:current-command > $temp-file
  try {
    $E:EDITOR $temp-file[name] </dev/tty >/dev/tty 2>&1
    edit:current-command = (slurp < $temp-file[name])[..-1]
  } else {
    file:close $temp-file
    rm $temp-file[name]
  }
}

Why do you use an else block for cleanup? I'd have thought a finally block would be more appropriate.

xiaqqaix (Telegram)

@telegram_84517825:elv.sh

Yeah, the use of else seems wrong here - else blocks are run when there are no exceptions

Kurtis Rader

@krader1961:matrix.org

I did it that way so that if something goes wrong I still had a chance to recover the contents of the temporary file. But in practice the only time that happens is if I deliberately exit Vim with :cq! so, yeah, I should probably change it to a finally block.

xiaqqaix (Telegram)

@telegram_84517825:elv.sh

Ah, that makes sense

Kurtis Rader

@krader1961:matrix.org

arekushi (Telegram): I set my env var like this so it is an absolute path: set-env EDITOR (search-external vim).

> put $E:EDITOR
▶ /usr/local/bin/vim

If you want the PATH resolution to be dynamic every time you invoke it then use xiaqqaix (Telegram)'s solution.
