Re: [Fish-users] a builtin AND a function?

2017-10-23 Thread Diego Zamboni 
Mark,

cd is a builtin, but the default fish installation comes with a function
called cd (which overshadows the builtin) which wraps the builtin and adds
some functionality such as recognizing "-" to mean "previous directory",
keeping the directory history, etc. You can see its definition by typing
"functions cd".

Re: [Fish-users] external command inside function fails on OSX

I'm not sure how PATH settings are propagated through functions. One quick
solution would be to just use the full path for all commands (e.g.
/usr/sbin/diskutil).

I also missed !! and !$ when I moved to fish. Someone on this list (can’t

Re: [Fish-users] Suspend?

2015-08-04 Thread Diego Zamboni 
Hi Mike,

 There doesn't seem to be a way to suspend a fish shell, ala the suspend 
 builtin in zsh, bash, etc. I'm wondering if this is a bug, and C-Z should 
 work (except in a login shell), or if it's a design feature. or if no one has 
 asked for it?

It works for me:

diego@cuper➜ sleep 50
press Ctrl-Z
'sleep 50' has stopped
diego@cuper➜ jobs
Job Group   State   Command
1   53568   stopped sleep 50
diego@cuper➜ bg
Send job 1 'sleep 50' to background
diego@cuper➜ fg
Send job 1, 'sleep 50' to foreground
^C~ 

  

Not sure where/how this is defined - I can’t find Ctrl-Z in the output from 
“bind”, but it must be defined somewhere.

 I'm not opposed to merging this, but I have to ask - why do you want to
 suspend your shell? Is there a use case that isn't covered by the state
 shared across shells such that exiting and restarting isn't sufficient?
 
 The use case isn't about shared data. In fact, I can't think of a use case 
 where for suspending a program that would be solved by that, so I'm curious 
 as to what your use cases are?
 
 I suspend programs to quickly switch between different environments, like 
 dropping out of vi to issue shell commands. In this case, the two 
 environments both happen to be command shells. In some cases, it's because 
 the shells need different values in the OS - userids, or some kind of virtual 
 environment, or possibly system call emulation layers. Sometimes, it's for 
 stuff in the shell, like needing cc or make to be something other than the 
 system versions. Come to think of it, fish sharing data may cause some of 
 those last ones to break. I'll have to try it and see now that I can switch 
 back and forth easily.

The only problem I had was that I had to edit and save bind_bang and

 Not for me.  For me, it does as Andrew Kreps noted--shows me the last command

Same for me. To search any part of past commands, I have to type the text I’m

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

2015-05-07 Thread Diego Zamboni 
Robert,

I couldn’t agree more. There are a few things I found frustrating in fish at 
first (some I still do, like the inability to recall previous 
commands/arguments with !! and !$ - I have to look more into coding those with 
functions), but over time I’ve found the interactive shell experience SO MUCH 
BETTER. For example, when I have to use bash on other machines, I miss the 
automatic history completion and Ctl-F to complete commands. I *love* the 
completion system and how everything can be defined as a function so it’s 
trivial to redefine default behaviors if you want.

Aleksey: fish is indeed not bash, but in a good way. There are many things that 
could be improved, for sure, but it’s great even now. The community and 
developers are friendly and helpful, and if you stick around, you’ll see that 
good-natured feedback is always received well and addressed promptly.

 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.

Re: [Fish-users] query about using alias with sudo

2015-03-05 Thread Diego Zamboni 
Mandeep,

Have you also changed root’s shell to fish? Otherwise it will not read that 
config file.

If I may make a side comment, I wouldn’t recommend using fish as root’s shell. 
As much as I like fish, its code is not nearly as mature as bash or sh, so 
there’s a higher likelihood of bugs, which under root could have bad 
consequences. Also, I always prefer to make root’s environment as uncomfortable 
as possible, so that I’m not tempted to spend in it any time beyond the 
strictly necessary :)

 I have not tested this. Make backups and ensure you have an alternative

 This functionality was altered before the release of fish 2.0.0.
 
 Commit 6eb66770a49944 [1] makes completions non-authoritative by default.
 If you pass the `--authoritative` argument to your completions, the
 behaviour you describe will return. However, this is not enabled for
 completions shipped with fish because of the difficulty in maintaining
 parity between these completions and the upstream program.
 
 With the next release of fish, a supported path for completions shipped by
 upstream vendors will be available; these can make use of the
 `--authoritative` option for even better syntax highlighting.
 
 Hope that helps!

 I first glance, I would say, that it is not a realistic feature.
 How could you tell if a given option is a right or a wrong one?
 
 For the command, work is easy: just ask the file system is there is
 such
 an executable program.
 But there is no Unix command which tells given a program and options if
 they are compatible.
 Of course, like autocompletion, you could forbid some options (but that
 would concern only very specific programs for which the set of good
 options can be easily known).
 Plus there should be some clever parsing, as for example ls --
 --unknownoption is a valid command (at least on the Ubuntu version I
 have).
 That is because I can create a file named --unknownoption.

Re: [Fish-users] ALT+Left and ALT+Right is not moving forward/backward in directory history

2014-11-01 Thread Diego Zamboni 
I found a solution - I am using Terminal.app, and in the “Keyboards” tab of the 
preferences I found the mappings for different key combinations, among them the 
mappings for Alt-Left and Alt-right (see attached screenshot). Those are the 
sequences that need to be used with the “bind” command to map to the 
appropriate functions:

bind \033f next-or-forward-word
bind \033b prevd-or-backward-word

And now Alt-left and Alt-right work as expected!

I don’t know if you are using Terminal.app or other terminal program, but I’m 
betting the solution must be a similar one.

Hope this helps,
—Diego

 I tried to push those two bind commands in ~/.config/fish/config.fish;
 but this didn't work.
 
 but if i do:
source ~/.config/fish/config.fish
 
 then it started working.
 any clues, what is wrong here..

 I found a solution - I am using Terminal.app, and in the “Keyboards” tab of 
 the preferences I found the mappings for different key combinations, among 
 them the mappings for Alt-Left and Alt-right (see attached screenshot). Those 
 are the sequences that need to be used with the “bind” command to map to the 
 appropriate functions:
 
 bind \033f next-or-forward-word
 bind \033b prevd-or-backward-word
 
 And now Alt-left and Alt-right work as expected!
 
 I don’t know if you are using Terminal.app or other terminal program, but I’m 
 betting the solution must be a similar one.
 
 Hope this helps,

 Hi,
 
 I’m having the same issue - Alt-left and Alt-right do nothing.
 
 “dirs” for me (on OSX as well) also shows just the current directory, but 
 “dirh” shows the full directory history. Also, prevd-or-backward-word and 
 next-or-forward-word work fine when invoked directly:
 
 a10022@cuper ~/Documents dirh
 /Users/a10022/Downloads  /  /Users/a10022/Documents  
 a10022@cuper ~/Documents prevd-or-backward-word 
 a10022@cuper / prevd-or-backward-word 
 a10022@cuper ~/Downloads nextd-or-forward-word 
 a10022@cuper / 
 
 So the functionality seems to be there, I think what’s failing are the key 
 bindings:
 
 a10022@cuper / bind | grep prevd-or
 bind \e\eOD prevd-or-backward-word
 bind \e\e\[D prevd-or-backward-word
 bind \eO3D prevd-or-backward-word
 bind \e\[3D prevd-or-backward-word
 bind \e\[1\;3D prevd-or-backward-word
 
 But I’m not sure what the magic sequence for Alt-left and Alt-right needs to 
 be. For example, these two commands make it so that I can use Alt-[ and 
 Alt-] to navigate the directory history:
 
 bind \e\[ prevd-or-backward-word
 bind \e\] nextd-or-forward-word
 
 I think it would be nice for fish to have a “capture key” mode that shows 
 you the sequence to use for any keys you press.
