vim有不少著名的grep插件,我使用過的有ack.vim,ag.vim和ctrlsf.vim,它們應該也是目前用戶最多的幾個了。java
起步比較早,早期後端grep工具是ack,後來也支持ag(the_silver_searcher),pt(the_platinum_searcher),rg(ripgrep)等工具了。它是一個比較傳統的grep插件,不支持異步,要等到grep結束後才能顯示結果,在大的項目中grep會卡好一陣子。它貌似也再也不維護,我N久前提交的pull request還掛在那,它最近的代碼更新在11個月前。git
它實際上是抄襲ack.vim,沒錯,是抄襲。在早期ack.vim還不支持ag時,它的做者在ack.vim代碼的基礎上稍微改了改,支持了ag。後來被ack.vim的做者給懟了,就放棄了對ag.vim的維護。目前功能上小於ack.vim。github
這是國人開發的一個插件, 後端grep工具支持ack/ag/pt/rg,同時也支持異步,不過須要Vim 8.0.1039+或者NeoVim才支持異步。這個插件很好用,在我開發Leaderf rg
以前一直使用的是它。express
Leaderf rg
顧名思義,後端基於rg,因爲是LeaderF的子功能,基因上就決定它完美支持異步。同時LeaderF又是一個非著名的模糊查找插件,這使它能夠在grep結果的基礎上再經過模糊匹配的方式進行二次過濾,來幫助用戶更快地鎖定目標,這是目前上面提到的插件所不具有的。vim
快速grep工具目前有ag, rg, pt, sift, ucg等。
我選擇rg有如下幾點緣由:後端
rg --help
看出來。Leaderf rg
使用介紹Leaderf rg
的使用也比較簡單,只要Leaderf[!]
+ rg命令和選項(同命令行上同樣)
就能夠了。
具體使用方法能夠用:Leaderf rg -h
來查看。app
usage: Leaderf[!] rg [-h] [-e <PATTERN>...] [-F] [-i] [-L] [-P] [-S] [-s] [-v] [-w] [-x] [--hidden] [--no-config] [--no-ignore] [--no-ignore-global] [--no-ignore-parent] [--no-ignore-vcs] [--no-pcre2-unicode] [-E <ENCODING>] [-M <NUM>] [-m <NUM>] [--max-depth <NUM>] [--max-filesize <NUM+SUFFIX?>] [--path-separator <SEPARATOR>] [--sort <SORTBY>] [--sortr <SORTBY>] [-f <PATTERNFILE>...] [-g <GLOB>...] [--iglob <GLOB>...] [--ignore-file <PATH>...] [--type-add <TYPE_SPEC>...] [-t <TYPE>...] [-T <TYPE>...] [--current-buffer | --all-buffers] [--recall] [--append] [--reverse] [--stayOpen] [--input <INPUT> | --cword] [--top | --bottom | --left | --right | --belowright | --aboveleft | --fullScreen] [--nameOnly | --fullPath | --fuzzy | --regexMode] [--nowrap] [<PATH> [<PATH> ...]] optional arguments: -h, --help show this help message and exit specific arguments: -e <PATTERN>..., --regexp <PATTERN>... A pattern to search for. This option can be provided multiple times, where all patterns given are searched. -F, --fixed-strings Treat the pattern as a literal string instead of a regular expression. -i, --ignore-case Searches case insensitively. -L, --follow Follow symbolic links while traversing directories. -P, --pcre2 When this flag is present, rg will use the PCRE2 regex engine instead of its default regex engine. -S, --smart-case Searches case insensitively if the pattern is all lowercase, case sensitively otherwise. -s, --case-sensitive Searches case sensitively. -v, --invert-match Invert matching. Show lines that do not match the given patterns. -w, --word-regexp Only show matches surrounded by word boundaries. This is roughly equivalent to putting \b before and after all of the search patterns. -x, --line-regexp Only show matches surrounded by line boundaries. --hidden Search hidden files and directories. By default, hidden files and directories are skipped. --no-config Never read configuration files. When this flag is present, rg will not respect the RIPGREP_CONFIG_PATH environment variable. --no-ignore Don't respect ignore files (.gitignore, .ignore, etc.). This implies --no-ignore-parent and --no-ignore-vcs. --no-ignore-global Don't respect ignore files that come from 'global' sources such as git's `core.excludesFile` configuration option (which defaults to `$HOME/.config/git/ignore`). --no-ignore-parent Don't respect ignore files (.gitignore, .ignore, etc.) in parent directories. --no-ignore-vcs Don't respect version control ignore files (.gitignore, etc.). --no-pcre2-unicode When PCRE2 matching is enabled, this flag will disable Unicode mode, which is otherwise enabled by default. -E <ENCODING>, --encoding <ENCODING> Specify the text encoding that rg will use on all files searched. -M <NUM>, --max-columns <NUM> Don't print lines longer than this limit in bytes. -m <NUM>, --max-count <NUM> Limit the number of matching lines per file searched to NUM. --max-depth <NUM> Limit the depth of directory traversal to NUM levels beyond the paths given. --max-filesize <NUM+SUFFIX?> Ignore files larger than NUM in size. This does not apply to directories. --path-separator <SEPARATOR> Set the path separator to use when printing file paths. --sort <SORTBY> This flag enables sorting of results in ascending order. --sortr <SORTBY> This flag enables sorting of results in descending order. -f <PATTERNFILE>..., --file <PATTERNFILE>... Search for patterns from the given file, with one pattern per line. (This option can be provided multiple times.) -g <GLOB>..., --glob <GLOB>... Include or exclude files and directories for searching that match the given glob.(This option can be provided multiple times.) --iglob <GLOB>... Include or exclude files and directories for searching that match the given glob. Globs are matched case insensitively.(This option can be provided multiple times.) --ignore-file <PATH>... Specifies a path to one or more .gitignore format rules files. --type-add <TYPE_SPEC>... Add a new glob for a particular file type. -t <TYPE>..., --type <TYPE>... Only search files matching TYPE. Multiple type flags may be provided. -T <TYPE>..., --type-not <TYPE>... Do not search files matching TYPE. Multiple type-not flags may be provided. <PATH> A file or directory to search. Directories are searched recursively. Paths specified on the command line override glob and ignore rules. --current-buffer Searches in current buffer. --all-buffers Searches in all listed buffers. --recall Recall last search. If the result window is closed, reopen it. --append Append to the previous search results. common arguments: --reverse show results in bottom-up order --stayOpen don't quit LeaderF after accepting an entry --input <INPUT> specifies INPUT as the pattern inputted in advance --cword current word under cursor is inputted in advance --top the LeaderF window is at the top of the screen --bottom the LeaderF window is at the bottom of the screen --left the LeaderF window is at the left of the screen --right the LeaderF window is at the right of the screen --belowright the LeaderF window is at the belowright of the screen --aboveleft the LeaderF window is at the aboveleft of the screen --fullScreen the LeaderF window takes up the full screen --nameOnly LeaderF is in NameOnly mode by default --fullPath LeaderF is in FullPath mode by default --fuzzy LeaderF is in Fuzzy mode by default --regexMode LeaderF is in Regex mode by default --nowrap long lines in the LeaderF window won't wrap If [!] is given, enter normal mode directly.
注意:若是:Leaderf
後面有感嘆號,會直接進入normal模式;若是沒有感嘆號,則是輸入模式,此時能夠輸入字符來進行模糊匹配過濾。能夠用tab鍵在兩個模式間來回切換。異步
Leaderf rg
基本支持rg全部的必要選項,用戶若是對rg命令比較熟悉,能夠在vim命令行內輸入:Leaderf
, 而後手敲rg命令,命令選項還能夠經過tab來補全。
固然,更聰明的作法是定義一些快捷鍵。例如:ide
" search word under cursor, the pattern is treated as regex, and enter normal mode directly noremap <C-F> :<C-U><C-R>=printf("Leaderf! rg -e %s ", expand("<cword>"))<CR> " search word under cursor, the pattern is treated as regex, " append the result to previous search results. noremap <C-G> :<C-U><C-R>=printf("Leaderf! rg --append -e %s ", expand("<cword>"))<CR> " search word under cursor literally only in current buffer noremap <C-B> :<C-U><C-R>=printf("Leaderf! rg -F --current-buffer -e %s ", expand("<cword>"))<CR> " search word under cursor literally in all listed buffers noremap <C-D> :<C-U><C-R>=printf("Leaderf! rg -F --all-buffers -e %s ", expand("<cword>"))<CR> " search visually selected text literally, don't quit LeaderF after accepting an entry xnoremap gf :<C-U><C-R>=printf("Leaderf! rg -F --stayOpen -e %s ", leaderf#Rg#visual())<CR> " recall last search. If the result window is closed, reopen it. noremap go :<C-U>Leaderf! rg --recall<CR> " search word under cursor in *.h and *.cpp files. noremap <Leader>a :<C-U><C-R>=printf("Leaderf! rg -e %s -g *.h -g *.cpp", expand("<cword>"))<CR> " the same as above noremap <Leader>a :<C-U><C-R>=printf("Leaderf! rg -e %s -g *.{h,cpp}", expand("<cword>"))<CR> " search word under cursor in cpp and java files. noremap <Leader>b :<C-U><C-R>=printf("Leaderf! rg -e %s -t cpp -t java", expand("<cword>"))<CR> " search word under cursor in cpp files, exclude the *.hpp files noremap <Leader>c :<C-U><C-R>=printf("Leaderf! rg -e %s -t cpp -g !*.hpp", expand("<cword>"))<CR>
參考:rg的glob語法。工具
順便說一下,直接在vim命令行敲:Leaderf rg
,就會有傳說中的"grep on the fly"
的功能哦,同時支持fuzzy和regex兩種模式。
不會。
首先,ripgrep已經足夠強大,基本不存在別的工具備而ripgrep沒有的功能。其次,ripgrep有編譯好的Windows、Linux和MacOS上的binary,能夠在這些平臺上很容易安裝。再者,因爲做者比較懶,不想再實現重複的功能。
