jvgrep is grep for japanese vimmer. you can find text from files that writen in another japanese encodings.


To compile jvgrep, you must install golang.

And type following

# go get


-8               : show result as utf8 text
-F               : PATTERN is a set of newline-separated fixed strings
-G               : PATTERN is a basic regular expression (BRE)
-P               : PATTERN is a Perl regular expression
-R               : search files recursively
-S               : verbose messages
-V               : print version information and exit
--enc encodings  : encodings: comma separated
--exclude regexp : exclude files: specify as regexp
                   (default: \.git|\.svn|\.hg)
--color [=WHEN]  : always/never/auto
-r               : print relative path
-f file          : obtain pattern file
-i               : ignore case(currently fixed only)
-l               : print only names of FILEs containing matches
-n               : print line number with output lines
-o               : show only the part of a line matching PATTERN
-v               : select non-matching lines

Supported Encodings:

for example,

# jvgrep 表[現示] "**/*.txt"

pattern should be specify with regexp. file can be specify wildcard. You can specify pattern with regular expression include multi-byte characters.. If you want to use own encodings for jvgrep, try to set environment variable $JVGREP_ENCODINGS to specify encodings separated with comma. If you problem about output of jvgrep (ex: output of :grep command in vim), try to set $JVGREP_OUTPUT_ENCODING to specify encoding of output.

  • utf-8
  • ucs-2
  • euc-jp
  • cp932
