"Default grep format command for `helm-do-grep-1'.
|
|||
|
|
Where:
|
|||
|
|
'%e' format spec is for --exclude or --include grep options or
|
|||
|
|
ack-grep --type option. (Not mandatory)
|
|||
|
|
|
|||
|
|
'%c' format spec is for case-fold-search,
|
|||
|
|
whether to use the -i option of grep. (Not mandatory)
|
|||
|
|
When you specify this spec, helm grep will use smartcase
|
|||
|
|
that is when a upcase character is found in pattern case will
|
|||
|
|
be respected and no \\='-i' option will be used, otherwise, when
|
|||
|
|
no upcase character is found in pattern always use \\='-i'.
|
|||
|
|
If you don't want this behavior, don't use this spec and
|
|||
|
|
specify or not the \\='-i' option.
|
|||
|
|
Note that with ack-grep this is not needed, just specify
|
|||
|
|
the \\='--smart-case' option.
|
|||
|
|
|
|||
|
|
'%p' format spec is for pattern. (Mandatory)
|
|||
|
|
|
|||
|
|
'%f' format spec is for filenames. (Mandatory)
|
|||
|
|
|
|||
|
|
If your grep version doesn't support the --exclude/include args
|
|||
|
|
don't specify the \\='%e' format spec.
|
|||
|
|
|
|||
|
|
Helm also support ack-grep and git-grep. The following is a
|
|||
|
|
default command example for ack-grep:
|
|||
|
|
|
|||
|
|
\(setq helm-grep-default-command
|
|||
|
|
\"ack-grep -Hn --color --smart-case --no-group %e -- %p %f\"
|
|||
|
|
helm-grep-default-recurse-command
|
|||
|
|
\"ack-grep -H --color --smart-case --no-group %e -- %p %f\")
|
|||
|
|
|
|||
|
|
You can ommit the %e spec if you don't want to be prompted for
|
|||
|
|
types.
|
|||
|
|
|
|||
|
|
NOTE: Helm for ack-grep support ANSI sequences, so you can remove
|
|||
|
|
the \"--no-color\" option safely (recommended).
|
|||
|
|
However you should specify --color to enable multi matches highlighting
|
|||
|
|
because ack disable it when output is piped.
|
|||
|
|
|
|||
|
|
Same for grep you can use safely the option \"--color=always\" (default).
|
|||
|
|
You can customize the color of matches using GREP_COLORS env var.
|
|||
|
|
e.g: (setenv \"GREP_COLORS\"
|
|||
|
|
\"ms=30;43:mc=30;43:sl=01;37:cx=:fn=35:ln=32:bn=32:se=36\")
|
|||
|
|
|
|||
|
|
To enable ANSI color in git-grep just add \"--color=always\".
|
|||
|
|
To customize the ANSI color in git-grep, GREP_COLORS have no effect,
|
|||
|
|
you will have to setup this in your .gitconfig:
|
|||
|
|
|
|||
|
|
[color \"grep\"]
|
|||
|
|
match = black yellow
|
|||
|
|
|
|||
|
|
Where \"black\" is the foreground and \"yellow\" the background.
|
|||
|
|
See the git documentation for more infos.
|
|||
|
|
|
|||
|
|
`helm-grep-default-command' and
|
|||
|
|
`helm-grep-default-recurse-command' are independent, so you can
|
|||
|
|
enable `helm-grep-default-command' with ack-grep and
|
|||
|
|
`helm-grep-default-recurse-command' with grep if you want to be
|
|||
|
|
faster on recursive grep.
|
|||
|
|
|
|||
|
|
NOTE: Remote grepping is not available with ack-grep, and badly
|
|||
|
|
supported with grep because tramp handles badly repeated
|
|||
|
|
remote processes in a short delay (< to 5s)."

|

Prefer RG by default if available.
|
|||
|
|
|

|
|
Update: PT is still mentionned in this documentation but it seems it
|
|||
|
|
doesn't exists anymore, or at least it is no more maintained.
|
|||
|
|
|
|||
|
|
Takes three format specs, the first for type(s), the second for
|
|||
|
|
pattern and the third for directory.
|
|||
|
|
|
|||
|
|
You can use safely \"--color\" (used by default) with AG RG and
|
|||
|
|
PT.
|
|||
|
|
|
|||
|
|
NOTE: Usage of \"--color=never\" is discouraged as it uses Elisp
|
|||
|
|
to colorize matched items which is slower than using the native
|
|||
|
|
colorization of backend, however it is still supported.
|
|||
|
|
|
|||
|
|
For ripgrep here is the command line to use:
|
|||
|
|
|
|||
|
|
rg --color=always --smart-case --no-heading --line-number %s -- %s %s
|
|||
|
|
|
|||
|
|
And to customize colors (always for ripgrep) use something like this:
|
|||
|
|
|
|||
|
|
rg --color=always --colors \\='match:bg:yellow' --colors \\='match:fg:black'
|
|||
|
|
\--smart-case --no-heading --line-number %s -- %s %s
|
|||
|
|
|
|||
|
|
This will change color for matched items from foreground red (the
|
|||
|
|
default) to a yellow background with a black foreground. Note
|
|||
|
|
that your color settings for RG will not work properly with
|
|||
|
|
multiples pattern if you have configured colors in rg config file
|
|||
|
|
instead of command line. For more enhanced settings of ansi
|
|||
|
|
colors see https://github.com/emacs-helm/helm/issues/2313
|
|||
|
|
|
|||
|
|
You must use an output format that fit with helm grep, that is:
|
|||
|
|
|
|||
|
|
\"filename:line-number:string\"
|
|||
|
|
|
|||
|
|
The option \"--nogroup\" allow this.
|
|||
|
|
The option \"--line-numbers\" is also mandatory except with
|
|||
|
|
PT (not supported).
|
|||
|
|
For RG the options \"--no-heading\" and \"--line-number\" are the
|
|||
|
|
ones to use.
|
|||
|
|
|
|||
|
|
When modifying the default colors of matches with e.g.
|
|||
|
|
\"--color-match\" option of AG or \"--colors\" option of ripgrep
|
|||
|
|
you may want to modify as well `helm-grep-ag-pipe-cmd-switches'
|
|||
|
|
to have all matches colorized with the same color in multi
|
|||
|
|
match.
|
|||
|
|
|
|||
|
|
Of course you can use several other options, see the man page of the
|
|||
|
|
backend you are using."
