# Search in Weechat buffers and logs (for Weechat 0.3.*)
|
|
#
|
|
# Inspired by xt's grep.py
|
|
# Originally I just wanted to add some fixes in grep.py, but then
|
|
# I got carried away and rewrote everything, so new script.
|
|
#
|
|
# Commands:
|
|
# * /grep
|
|
# Search in logs or buffers, see /help grep
|
|
# * /logs:
|
|
# Lists logs in ~/.weechat/logs, see /help logs
|
|
#
|
|
# Settings:
|
|
# * plugins.var.python.grep.clear_buffer:
|
|
# Clear the results buffer before each search. Valid values: on, off
|
|
#
|
|
# * plugins.var.python.grep.go_to_buffer:
|
|
# Automatically go to grep buffer when search is over. Valid values: on, off
|
|
#
|
|
# * plugins.var.python.grep.log_filter:
|
|
# Coma separated list of patterns that grep will use for exclude logs, e.g.
|
|
# if you use '*server/*' any log in the 'server' folder will be excluded
|
|
# when using the command '/grep log'
|
|
#
|
|
# * plugins.var.python.grep.show_summary:
|
|
# Shows summary for each log. Valid values: on, off
|
|
#
|
|
# * plugins.var.python.grep.max_lines:
|
|
# Grep will only print the last matched lines that don't surpass the value defined here.
|
|
#
|
|
# * plugins.var.python.grep.size_limit:
|
|
# Size limit in KiB, is used for decide whenever grepping should run in background or not. If
|
|
# the logs to grep have a total size bigger than this value then grep run as a new process.
|
|
# It can be used for force or disable background process, using '0' forces to always grep in
|
|
# background, while using '' (empty string) will disable it.
|
|
#
|
|
# * plugins.var.python.grep.timeout_secs:
|
|
# Timeout (in seconds) for background grepping.
|
|
#
|
|
# * plugins.var.python.grep.default_tail_head:
|
|
# Config option for define default number of lines returned when using --head or --tail options.
|
|
# Can be overriden in the command with --number option.
|
|
#
|
|
#
|
|
# TODO:
|
|
# * try to figure out why hook_process chokes in long outputs (using a tempfile as a
|
|
# workaround now)
|
|
# * possibly add option for defining time intervals

|
|
# * added config option for filter logs we don't want to grep
|
|
# * added the posibility to repeat last search with another regexp by writing
|

log <file>: Search in one log that matches <file> in the logger path.
|
|
Use '*' and '?' as wildcards.
|
|
buffer <name>: Search in buffer <name>, if there's no buffer with <name> it will
|
|
try to search for a log file.
|
|
stop: Stops a currently running search.
|
|
-a --all: Search in all open buffers.
|
|
If used with 'log <file>' search in all logs that matches <file>.
|
|
-b --buffer: Search only in buffers, not in file logs.
|
|
-c --count: Just count the number of matched lines instead of showing them.
|
|
-m --matchcase: Don't do case insensitive search.
|
|
-H --hilight: Colour exact matches in output buffer.
|
|
-o --only-match: Print only the matching part of the line (unique matches).
|
|
-v -i --invert: Print lines that don't match the regular expression.
|
|
-t --tail: Print the last 10 matching lines.
|
|
-h --head: Print the first 10 matching lines.
|
|
-n --number <n>: Overrides default number of lines for --tail or --head.
|
|
-A --after-context <n>: Shows <n> lines of trailing context after matching lines.
|
|
-B --before-context <n>: Shows <n> lines of leading context before matching lines.
|
|
-C --context <n>: Same as using both --after-context and --before-context simultaneously.
|
|
<expression>: Expression to search.
|

|
|
Grep buffer:
|
|
Input line accepts most arguments of /grep, it'll repeat last search using the new
|
|
arguments provided. You can't search in different logs from the buffer's input.
|
|
Boolean arguments like --count, --tail, --head, --hilight, ... are toggleable
|
|
|
|
Python regular expression syntax:
|
|
See http://docs.python.org/lib/re-syntax.html
|
|
|
|
Grep Templates:
|
|
%{url [text]}: Matches anything like an url, or an url with text.
|
|
%{ip}: Matches anything that looks like an ip.
|
|
%{domain}: Matches anything like a domain.
|
|
%{escape text}: Escapes text in pattern.
|
|
%{simple pattern}: Converts a pattern with '*' and '?' wildcards into a regexp.
|
|
|
|
Examples:
|
|
Search for urls with the word 'weechat' said by 'nick'
|
|
/grep nick\\t.*%{url weechat}
|
|
Search for '*.*' string
|
|
/grep %{escape *.*}
