pisces ['paɪsiz]
is a plugin for fish that helps you to work with paired symbols like ()
and ''
in the command line. Just as in your favorite text editor!
Here |
denotes the current cursor position. No manual cursor motion involved ✨
- autocloses pair symbol:
... |
+ ( ⇒
... (|)
- skips the closing symbol:
...|)
+ ) ⇒
... )|
- removes empty pairs:
...([|])
+ backspace ⇒
...(|)
+ backspace ⇒
...|
- the set of pairs is configurable
-
Using fisherman:
fisher install laughedelic/pisces
-
Using oh-my-fish:
omf install pisces
NOTE:
The minimum recommended version of fish is v2.6, because
- it has a feature called bracketed (a.k.a safe) paste which solves the problem with pasting strings containing paired symbols (they get autoclosed), see #6 for details.
The minimum required version of fish is v2.3, because
- there was a bug #2210 in v2.2 which would brake quotes handling
- it uses
string
builtin which was introduced in v2.3
You can set the $pisces_pairs
universal variable and launch a new fish session to reload key bindings:
set -U pisces_pairs $pisces_pairs '<,>' '`,`' '«,»'
Note that at the moment pisces works correctly only with single-symbol delimiters.
The default set of pairs:
(,)
parenthesis[,]
brackets{,}
braces","
double quotes','
single quotes
Here are some ideas for further development (some are already implemented):
-
autoclosing:
- ignore closing
"
when trying to autocomplete a var (see v0.3.0) - #5 (WIP): context-dependent autoclosing. Some particular cases:
- ? autoclose only when surrounded by non-word characters
- ignore escaped symbols:
...\|
+ ( =>...\(|
(or autoclose them?) - ? ignore single quote (apostrophe) in the comments
- multi-character pairs, similar to simple code-snippets:
for | end
,if | end
,begin; |; end
, etc.
- ignore closing
-
empty pairs removal:
- treat pair as empty if it has only whitespaces inside:
...(| )
+ backspace ⇒...|
-
remove an empty pair even when the cursor is after it (or go inside?):...()|
+ backspace ⇒...|
or...(|)
(this is probably confusing) - key bindings for
^W
and similar?foo bar(|)
+ ctrlw ⇒foo |
- treat pair as empty if it has only whitespaces inside:
-
optional alt+symbol keybindings that do something else, for example:
- surround the current token
- just insert single symbol
- jump after the closing symbol
-
#3: support for vi-mode
-
autoreload on the
$pisces_pairs
var changes -
restore previous keybindings instead of erasing them
