Basic incremental history search for fish shell

re-search

Basic incremental history search, implemented to be used with fish shell.

It doesn't support all the terminal implementations because of some ANSI escape sequences used, and is only tested on GNU/Linux.

Install

• Compile and add the binary to your PATH.
• Copy the file re_search.fish to the directory ~/.config/fish/functions/.
• Add the binding to ~/.config/fish/functions/fish_user_key_bindings.fish:

bind \cr re_search

Duplicate history entries

Because of performance issues with large history file, the duplicate check is disabled by default. If you want to enable it, just pass the correct cflag to make:

make CFLAGS=-DCHECK_DUPLICATES

Internal key bindings

• C-r, up, pg-up: backward search.
• C-s, down, pg-down: forward search.
• C-c, left, esc, home: cancel search.
• C-e, right, end: accept result.
• Enter: execute result.

Customize the prompt

• Stop tracking changes on config.h

git update-index --assume-unchanged config.h

• Redefine the prompt macro in config.h, for example, a very simple prompt could look like:

#define PROMPT(buffer, direction, index, result) \
        do { fprintf(stderr, "%s", result); } while (0)

or, a more compact version of the native prompt:

#define PROMPT(buffer, direction, index, result) \
        do { \
        	fprintf(stderr, "[%c%d] %s", direction[0], index, buffer); \
        	if (index > 0) {\
	        	int i = 0; \
        		i = fprintf(stderr, " > %s", result); \
        		fprintf(stderr, "\033[%dD", i); \
        	} \
        } while (0)
