Re: [Fish-users] expr command

Mark,

Good question. expr is a system command, so it's documented through the usual 
routes: https://linux.die.net/man/1/expr

Hey Mark,

Check out http://fishshell.com/docs/current/commands.html#prevd . I think

Re: [Fish-users] fish_prompt.fish not getting called

[Robert Carpenter]

Hey Mark,

I've seen this too, and I spent some time digging around in the source today 
and I don't think there is a way around it: 
https://github.com/fish-shell/fish-shell/blob/cb352317bdd421d140771de62c23ee3c32138502/src/screen.cpp#L956-L961

Someone can correct me if I'm wrong here, but I believe the goal here is for 
fish to present something usable in all situations and when the prompt is too 
long, usability starts to decrease rapidly.

Re: [Fish-users] Print and update information below commandline?

[Robert Carpenter]

Hey Jakob,

I thought I'd chime in with the implementation I have running, just for the 
sake of completion:

fish -v
fish, version 2.1.2-1228-g89da096

.config/fish/functions/expand-dot-to-parent-directory-path.fish :

function expand-dot-to-parent-directory-path -d 'expand ... to ../.. etc'
# Get commandline up to cursor
set -l cmd (commandline --cut-at-cursor)

# Match last line
switch $cmd[-1]
case '*..'
commandline --insert '/..'
case '*'
commandline --insert '.'
end
end

.config/fish/config.fish :

function fish_user_key_bindings
  bind . 'expand-dot-to-parent-directory-path'
end

Now, mine also doesn't have the second line preview that you mentioned, but I 
thought it might be helpful to show another way to accomplish the period 
expansion.

I have a hunch that the complete command might be able to do what is needed, 
but I haven't looked into it.

Re: [Fish-users] 5 minutes fish from 15 years bash impression

[Robert Carpenter]

Aleksey,

I honestly can't decide if you're trying to troll the mailing list or if you 
have legitimate questions. I'm going to take a risk of feeding the troll here 
in hopes that you're actually, honestly trying to understand fish-shell.

To save yourself some time, I'll put the summation at the top. Continue reading 
if you wish. 

To sum up: Fish shell is not bash. It tries to do things better. Sometimes that 
means different. It takes some getting used to.

And now a little more:

Several of the features you've suggested could be helpful, but I think it is 
important to remember that fish-shell is not, nor does it try (or even want) to 
be bash or even bash compliant. The interaction is *necessarily* different.

In my experience, bash is different, but equally frustrating when looking for 
help on builtins:

When I run `man for`, I get a man page or BUILTIN(1)...which lists all the 
builtin commands, does absolutely nothing to explain the behavior of the 'for' 
command, and (perhaps more importantly) doesn't suggest any further recourse 
for understanding what I am curious about.

Now, perhaps I'm missing some subtlety about bash -- I used it recklessly for 
about 8 years without ever learning much about it. But the principle of 
discoverability is completely missing from that experience. 

`env NAME=value command` is a perfectly acceptable system. It is *different*. 
But it is different for good reasons. It is more obvious to the user, less 
ambiguous to the interpreter, and obeys the principals of consistency, 
composition, and modularity (env is a command, which sets an environment 
variable, and then runs a given argument in the altered environment). These 
rules and others are available on the wikipedia page for the Unix Philosophy[1].

As for fetching help on every command when you make an error, that is actually 
the principal of discoverability at work. It is the default paradigm for any 
well designed shell tool, why should the shell itself be different? If you find 
yourself wanting examples, have a look at ssh, cp, and scp. 

I'll admit, when I first started using fish-shell, I was frustrated by the fact 
that help opened the browser by default. But my workflow is frequently 
switching back and forth between the shell and chrome (read: stackoverflow). 
Why not provide a richer help experience, where related commands can be easily 
found, rich on page searching is still available (and probably better)? I 
honestly do think that fish could use a better help experience, but I also 
don't think your method of requesting it is helpful at all.

Robert

 Not really good: the default PAGER is 'less' which doesn't fully
 comply with 'quick and easy'. Well, if to trim NAME section and quick

 output with 'cat' it will be almost like 'help' in bash, but:
 
 PAGER=cat man for
 fish: Unknown command 'PAGER=cat'. Did you mean to run man with a
 modified environment? Try 'env PAGER=cat man…'. See
 the help section on the set command by typing 'help set'.
 
 I recall, that I've read something about fish doesn't like
 subshells. Well, it's good to set variables inside pipes: I like
 that! But, here I want quick and easy way to use temporary settings.
 Ok, let's try what error said:
 
 env PAGER=cat man for
 No manual entry for for
 
 
 OMG, what was that?? It set PAGER and forgot all other variables? I
 guess, it executed '/usr/bin/env' which is not related to any shell
 and behaves how it wants, thus not a good method. I just want a
 subshell here with a quick and concise:
 
 PAGER=cat man for
 
 And it is kind of cumbersome to add 'env' here (even if it worked)...
 
 
 It's rather simple. Just type 'for' and press enter to see help text .
 
 Seriously? Making errors just to get inline help is not the right way
 to do it. It will not work for all commands (f.ex. 'set' and 'echo').
 Moreover, I don't need inline help every time I make real mistake,
 obviously...
 
 I see, that command built-ins have '--help' option. This is not unified way:
 
 1. no '--help' for syntactic statements like 'for', 'if'.
 2. With '--help' there is no clarity that this is sure built-in  When
 I type 'help COMMAND' I am sure that this is help about built-in. When
 I type 'COMMAND --help' I'm not sure if this is built-in or not (maybe
 there is no such built-in and this is help about executable util).
 
 
 
 Btw, if someone is interested, I decided to look at 'fish' 

Re: [Fish-users] Change default path from ~/ to ~/Sites

[Robert Carpenter]

In the past, my approach to this has been to just define an alias something 
along the lines of:

alias scd cd ~/Sites

At times, I've also taken the approach of instructing whatever Terminal app I'm 
using at the time to just start in whatever directory is occupying most of my 
time.

You may also be interested in $CDPATH. From 
fishshell.com/docs/current/commands.html#cd :

 If DIRECTORY is a relative path, the paths found in the CDPATH environment 
 variable array will be tried as prefixes for the specified path.

It is *possible* that setting $HOME will get you what you want, but I'd be 
pretty reluctant to do that because of how many different ways $HOME is 
usedyou'll likely end up with all manner of nonsense dotfiles in your Sites 
folder.

[Fish-users] Control key to accept part of a command completion suggestion?

[Robert Carpenter]

Hi fish-users,

I've been running a lot of similar commands lately and I've been really
grateful for the fish command suggestion feature. One thing I've come
across is a situation where I only want to take the next word or two from
the suggestion and then finish the command differently from the way fish
suggested.

As an example, if the command history contains:

ssh robert@server 'ls /home'

then when I type 'ssh' the suggestion will be the full command. If I
instead want to run `ssh robert@server 'ls /etc'` I can either type out the
full command or accept the full completion and ^W back over a few words to
put in what I want.

I am thinking that it would be useful for me to have a complete next word
key, which would take the completion up to some token marker (whitespace or
quote or whatever makes sense here). Then my input strategy would be more
like this:

- type ssh, see suggestion for `ssh robert@server 'ls /home'`
- ^G to take 'robert@server'
- type the rest of the command manually

Thoughts?

Re: [Fish-users] Control key to accept part of a command completion suggestion?

Okay. That isn't documented anywhere I can find, even now that I know what
it is. Before sending this I checked the Autosuggestion sections under both
Tutorial and Documentation. I was trying to be helpful suggesting a feature
that didn't exist.

It took some fiddling around to sort out what you were talking about
because I don't use the arrow keys to accept the completion in favor of
ctrl+f. I thought you were referring to opt+f or opt+ctrl+f instead of
opt+right.

I just spent some time looking into what tool builds the documentation so I
can submit a pull request for the docs to include this information but
decided I was walking down the wrong path when I was reading the makefile.
What toolset is used to generate the html docs from doc_src files?

suggested I explicitly set my path in config.fish and that has worked. The
line in my ~/.config/fish/config.fish file is:

set -x PATH /usr/local/bin /usr/bin /bin /usr/local/sbin /usr/sbin /sbin

I'm sure there are drawbacks to this method, but it has worked for me for a
few months now.

Cheers
Robert

 There's been a lot of discussion of how to properly set $PATH.
 $fish_user_paths works but only if you want to append to the $PATH. I use
 Homebrew to keep git, MySql, and many other formula's up-to-date. If I add
 /usr/local/bin/ to $fish_user_paths it appends and Fish still uses the git
 version located in /usr/bin/ which is the OS X default installed and
 out-of-date version.

 What's the proper way to prepend to $PATH so that your Homebrew formulas
 take precedence?

[Fish-users] Rearranging my $PATH

[Robert Carpenter]

Hey Fish Users,

My $PATH has the following: /usr/bin /bin /usr/sbin /sbin /usr/local/bin

I've recently upgraded my git, and homebrew links it into /usr/local/bin,
but the system git, which is installed in /usr/bin is still activated when
I execute a git command. Homebrew has been warning me about this for ages
but it hasn't ever really bit me until now.

From searching around the fish-shell issues on github, I gather that this
part of the path is generated from /etc/path somewhere along the startup
sequence. Config files or fish env functions then either add to the
beginning or end of the path depending on what it needs.

I opened up /etc/path and rearranged the items in there, exited all
instances of fish, and reopened a terminal to find that nothing had
changed.  My path still places /usr/local/bin at the end of the path,
rather than the beginning.

Whats the trick?

Thanks
Robert

Re: [Fish-users] “fg -”

[Robert Carpenter]

Elias,

I do this all the time under fish and have no problem. ^z to background a
running task, `jobs` to see what is running, `fg` or `fg N` to bring
something forward.  It even works with the `command ` syntax to background
a job at command time.

Robert

 Hi,

 In bash, I regularly use the “fg -” shortcut (it means switch to
 “previous job“, while “fg +” means “current job”).  It is handy for
 alternating between two jobs.

 As far as I can see, fish's “fg” cannot do this, or am I missing
 something?  If not, are there any plans to support this particular
 “bashism“ in fish?

Re: [Fish-users] Fish version of [[?

[Robert Carpenter]

Hey Robert,

The fish replacement for [[ is test. See the docs here:
http://fishshell.com/docs/2.0/commands.html#test

For your specific application, you might get some mileage out of contains (
http://fishshell.com/docs/2.0/commands.html#contains ) or case (
http://fishshell.com/docs/2.0/commands.html#case )

Hope this helps

Good thought, but I don't think so:

rob ~ type cd

I had a similar thought and went down this path in the past, I think.  Any

Re: [Fish-users] aliasing pushd

[Robert Carpenter]

Welp, there it is. I feel silly.  It is working now.   I had just assumed
that function was the fish builtin.  I see that the fish version is much
more elaborate.

Thanks, Dag!

 That there *is* calling `builtin cd`!  I suggest removing it (presumably
 you have that in ~/.config/fish/functions/cd.fish or something like that)
 so the one that ships with fish is used instead, and then use a variable
 listener function instead of a cwd event:

 function on_new_cwd -v PWD
 echo new cwd is $PWD
 end

[Fish-users] Autoloading functions from .config/fish/functions seems to be broken, or I am missing something.

[Robert Carpenter]

Hello all,

Little bit by little bit I've been porting bash functions from my bash
workflow over to fish functions and have had great success, with one
caveat.  I haven't been able to get fish to autoload files from the
functions/ directory at all.  For now I'm just stashing everything in the
.config/fish/fish.config file and it all works fine.  Eventually though,
I'd like to have my functions broken out in a better organized scheme like
.config/fish/functions/git_commands.fish etc.

I spent some time searching through the mailing list and the github issue
tracker and wasn't able to find any solution that worked for me, as the
only similar problem was solved by updating to fish 1.21 and I am already
on fish 2.0.

As an example, I've copied out a few functions from the readymade prompts
from the web config into a .fish file which will not load at startup.

The command sequence below seems like I've explored all the options, but I
could very well be missing something.

Any suggestions are appreciated, for until then I am putting everything in
my fish.config.

Thanks
Robert
