因為原本的 CPAN Shell 啟動時間慢，累贅的資訊太多，太多 Prompt，且對新手來說，太多預設設定要做，但新手只是需要儘快準備一個完整的開發環境來寫 Perl 程式碼而已！然而 CPAN Shell 由於太古老，該程式碼已經相當難維護、整理，所以一直沒有良好的修正。更別說是 CPANPLUS ，CPANPLUS 本身又相依於一堆模組，簡直是疊床架屋，對新手來說，安裝好 CPANPLUS 甚至要花上 10 分鐘！<br /><br />所以 Miyagawa 寫了 cpanminus ，這個模組 CPAN Shell 啟動時間相當的快，而且不相依於其他累贅的模組如 Moose... :-P<br /><br />cpanminus 只需要你有一個 C Compiler, Module::Build , ExtUtils::MakeMaker (Perl 都內建了), 甚至直接內嵌了 HTTP::LIte 模組。<br /><br />所以安裝 cpanminus 根本不需要花上超過 3 秒的時間！想想看你在升級 CPAN 或是 CPANPLUS 的時候多麼痛苦！！<br /><br />再來，常有使用者提出若無 root 權限，該如何安裝 CPAN 模組，這個問題一直是長期以來困擾大家的！而且又無完善解法。<br /><br />只要以非 Root 使用者執行 cpanm 安裝模組，該模組自動會裝到 home 目錄底下 ~/perl5 ，也不需另外自行設定！<br /><br />安裝方式相當簡單:<br /><br /><code>cd ~/bin<br />wget http://xrl.us/cpanm<br />chmod +x cpanm</code><br /><br />這樣就可以了，因為 cpanm 只是一個單一的執行檔！<br /><br />使用方式:<br /><br /><code>cpanm Module<br />cpanm MIYAGAWA/Plack-1.0000.tar.gz<br />cpanm ~/mydists/MyCompany-Framework-1.0.tar.gz<br />cpanm http://example.com/MyModule-0.1.tar.gz<br />cpanm http://github.com/miyagawa/Tatsumaki/tarball/master<br />cpanm --interactive Task::Kensho</code><br /><br />你也可以到 github 上取得最新的版本！ @miyagawa ROCKS!!<br /><br /><a href="http://github.com/miyagawa/cpanminus">http://github.com/miyagawa/cpanminus</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-9135984168769970652?l=c9s.blogspot.com' alt='' /></div></content>

Once you write a plugin , you will need it to be auto-installable. <a href="http://github.com/c9s/vimana">Vimana</a> is a script manager , which parses script files, and looks for a "script type:" tag to install the script.<div><br /></div><div>For example , if you have script , which is a ftplugin , then you should write:</div><div><br /></div><script src="http://gist.github.com/291385.js?file=ann.vim"></script><div><br /></div><div>in your script file. cases is ignored.</div><div><br /></div><div>then the plugin could be installed via Vimana script manager.</div><div><br /></div><div><br /></div><div>Or if you have multiple file to install , you can put your script files in this kind of directory structure:</div><div><br /></div><div>plugin/script.vim</div><div>ftplugin/script.vim</div><div>doc/script.txt</div><div><br /></div><div>then tar it and upload to vim.org site , the plugin could be installed via Vimana too.</div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-1372556132410632844?l=c9s.blogspot.com' alt='' /></div></content>

Vimana 的移除功能總算是找時間弄好了，兩個新的 Feature:<div><br /></div><div>1. Customizable Runtime Path:</div><div><br /></div><div>$ vimana install [plugin] --runtime-path [path]</div><div><br /></div><div>可以指定要安裝的 Runtime Path , 可在 .vimrc 內加上 set runtimepath+=[your/path] 。</div><div><br /></div><div>2. To uninstall Plugin:</div><div><br /></div><div>$ vimana remove [plugin] </div><div><br /></div><div>即可移除安裝</div><div><br /></div><div>或者強迫移除安裝:</div><div><br /></div><div>$ vimana remove [plugin] --force</div><div><br /></div><div>基本上 Installation 的 Record 都是以 JSON 格式置放在 ~/.vim/record 內，所以若有其他的 implementation 也可以很輕易的讀取，VimL 則可以直接 eval 該 record 來取得資料。</div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-2952210460665390079?l=c9s.blogspot.com' alt='' /></div></content>

Pango 裡頭的 text_extents 意義與 Cairo 的 text_extents 不太一樣。在 Pango 裡頭取得的 text extents 會有 ink 以及 logical 兩種， ink 是指包含文字的最小範圍，logical 則是整個文字 (由 baseline 往上到該 font 的 ascent 以及往下到該 font 的 descent 的範圍)<div><br /></div><div>因此可以先取得 baseline ，接著由 logical 或 ink 換算出不一樣的 ascent 與 descent 。</div><div><br /></div><div>範例如下:</div><br /><script src="http://gist.github.com/265197.js?file=pango-extents.pl"></script><br /><div>繪製成圖就很容易理解了:</div><div><br /></div><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_i3PNCkrh-3k/SznkvUZ_KcI/AAAAAAAAJHM/vNHkiFscjWs/s1600-h/pango.png"><img style="cursor:pointer; cursor:hand;" src="http://4.bp.blogspot.com/_i3PNCkrh-3k/SznkvUZ_KcI/AAAAAAAAJHM/vNHkiFscjWs/s400/pango.png" border="0" alt="" id="BLOGGER_PHOTO_ID_5420615128099793346" /></a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-8876290418687080864?l=c9s.blogspot.com' alt='' /></div></content>

<a href="http://github.com/c9s/Vimana">Vimana</a> 現在支援了 Makefile 以及 Rakefile 的安裝，您只需要在 Makefile 或 Rakefile 內提供 install 的規則 (Rule) 即可。 大部分在 github 上的 vim script 專案都提供了 Rakefile 或是 Makefile 所以都可以輕易的安裝好。<div><br /></div><div>如果未提供 Makefile 或是 Rakefile ，那麼也可以使用 Vim Meta file 來做安裝。再不然可幫你偵測目錄結構，若是符合 Vim Runtime Path 的結構，那麼安裝就可成功。</div><div><br /></div><div>另外花了一些時間將相依的模組減少，讓相依性模組的安裝不會如此痛苦。<br /><div><br /></div><div>我也新增了針對 vim.org 提供的類型資訊的 leak 可以剖析 script 內容來了解 script 類型，目前支援 colorscheme , compiler, indent , syntax 等等的類型偵測。</div><div><br /></div><div>測試過的套件如下:</div><div><br />$ vimana install the-nerd-tree<br />$ vimana install autocomplpop<br />$ vimaan install gsession.vim<br />$ vimana install snipmate<br />$ vimana i svg.vim<br />$ vimana i railscasts-theme<br />$ vimana i dark-ruby<br />$ vimana i bufexplorer.zip<br />$ vimana i xml.vim<br /><br />well, i still need more test cases. ;-)</div></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-8120894983645125218?l=c9s.blogspot.com' alt='' /></div></content>

<a href="http://github.com/c9s/Vimana">Vimana</a> supports for Makefile and Rakefile now. most vim script projects on github have its own rakefile or makefile, so that if a archive file (tar, tar.gz, zip) contains a makefile, rakefile or vim meta file. Vimana would use makefile/rakefile or meta file as its installer strategy.<br /><br />and I tried to reduce some dependencies, so that installation won't be such pain.<br /><br />I also added script inspecting feature, which inspects the script code to decide where to installer. colorscheme, compiler ,indent types are supported.<br /><br />current tested cases:<br /><br />$ vimana install the-nerd-tree<br />$ vimana install autocomplpop<br />$ vimaan install gsession.vim<br />$ vimana install snipmate<br />$ vimana i svg.vim<br />$ vimana i railscasts-theme<br />$ vimana i dark-ruby<br />$ vimana i bufexplorer.zip<br />$ vimana i xml.vim<br /><br />well, i still need more test cases. ;-)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-7616249022412005172?l=c9s.blogspot.com' alt='' /></div></content>

Vim script 有時候是非常煩人的東西，因為你每次都需要把他們一一複製到你的 VIM Runtime Path 裡頭 (通常為 `~/.vim`):<br /><br />所以假設現在要安裝 cpan.vim 這個套件，那麼就得這樣做:<br /><br /># go to libperl.vim page , download the libperl.vim file<br /># copy libperl.vim to ~/.vim/autoload/<br /><br /># go to search-window.vim page , download the search-window.vim file<br /># copy search-window.vim to ~/.vim/autoload/<br /><br /># download cpan.vim<br /># copy cpan.vim to ~/.vim/plugin/<br /><br /># config .vimrc to usage cpan.vim<br /><br />以上這些都還不是小問題，問題是 vim script 裡頭並不是每個檔案都標記了版本資訊，所以有時候換上了新版的 plugin ，可能導致其他東西爛掉。<br /><br />另外一種方式是 Vimball , Vimball 的方式相當好，但是並不是每個寫 plugin 的人都懂得如何使用 vimball , 再者 vim.org 並不規定你一定要用 vimball 才可以上傳，而且 Vimball 還是有他侷限的地方。<br /><br /><a href="http://github.com/c9s/vim-packager">VIM::Packager</a> 就是幫你做這樣的事情，安裝 cpan.vim 可以相當容易:<br /><br />$ cd cpan.vim<br />$ vim-packager build # 讀取 META 檔案 (包含 相依性資訊、套件名稱、版本、Vim 相容版本 ... etc ) 接著產生 Makefile<br />$ make install # 為你安裝所需要的相依套件，並建立紀錄<br /><br />若要移除:<br /><br />$ make uninstall<br /><br /><h3>使用 VIM::Packager 建立 Plugin</h3><br />步驟相當簡單，先建立作者資訊<br /><br />$ cat &gt; ~/.vim-author<br />author: Cornelius<br />email: cornelius.howl@DELETE.ME.gmail.com<br />^D<br /><br />$ mkdir your-plugin.vim<br />$ cd your-plugin.vim<br />$ vim-packager init # 這樣會為你產生 META 檔案、以及建立所需要的資料夾，並且利用範本為你建立文件<br /><br />$ vim META # 編輯套件資訊 (你還可以在 META 裡面加上 =script_id ，script id 對應此套件在 vim.org 的 id ，每當要釋出新版，便可以直接上傳 )<br /><br />META file 的格式相當簡單，請看:<br /><script src="http://gist.github.com/238829.js?file=gistfile1.txt"></script><br /><br />接著只需要再加上 plugin 的版本資訊即可:<br /><br />$ vim vimlib/plugin/your-plugin.vim # 加上 『 " Version: 0.1 』 版本資訊<br />$ vim-packager build # 便會產生 Makefile<br /><br />$ make dist # 幫你用 tar 打包起來<br /><br />$ make bump # 提昇版本<br /><br />$ make upload # 自動上傳到 vim.org<br /><br />以上三個動作現在可以直接用 $ make release 串起來，也就是:<br /><br />$ make release # tar 打包、提昇版本、自動上傳一次做到好。<br /><br /><br />當你在開發的時候，你也可以不需要安裝，可以利用 ln 來幫你直接連結到正在開發的檔案:<br /><br />$ make link<br /><br />或是<br /><br />$ make link-force # 強制連結<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-8163960979835457306?l=c9s.blogspot.com' alt='' /></div></content>

Ctrl-n , Ctrl-p 可以上下選擇 completion item, Ctrl-j , Ctrl-k 能夠跳至上一個/下一個 package，ESC 可直接關閉 completion window。<br /><br />有空在將這個 completion window generalize ，那麼便可以很容易的支援其他 Language。<br /><br />下一步想做的是 function preview ，由於在 Perl 的 Subroutine 內，我們可以用各種方式取用 Arguments ，所以若要自動 parse function argument 作為 completion 的提示，並不容易。初步的想法是，可以將一個 function 的最初幾行做預覽。那麼哪怕忘記 function 該怎麼 call ，只需要叫出預覽視窗即可。<br /><br />目前 perl-completion.vim 還在 github.com/c9s/cpan.vim 內。昨天晚上把所有 perl 相關函式整理至 autoload/libperl.vim ，以及將各 plugin 切割出來，如 ctags-search.vim , cpan.vim , perl-completion.vim , perl-function-search.vim 等。<br /><br />試想在這樣的 plugin 開發，未來可以在 Vimana 實做 : 自動建立 vim plugin 框架，自動產生 makefile，dependency check, plugin version check 之類的功能。<br /><br />目前的 perl-completion.vim 放在 <a href="http://github.com/c9s/cpan.vim/">http://github.com/c9s/cpan.vim/</a> 內。<br /><br /><br />安裝方式如下:<br /><br />使用 git 將 repository checkout 出來<br /><br />$ git clone git://github.com/c9s/cpan.vim.git<br />$ cd cpan.vim<br />$ make install<br /><br />安裝 cpan.vim 同時有下列幾種功能: perl function search , ctags search , cpan module search , perl-completion<br /><br />相關文章:<br /><a href="http://c9s.blogspot.com/2009/10/cpanvim-now-supports-ctags-search.html">http://c9s.blogspot.com/2009/10/cpanvim-now-supports-ctags-search.html</a><br /><a href="http://c9s.blogspot.com/2009/09/cpanvim.html">http://c9s.blogspot.com/2009/09/cpanvim.html</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-1761721664042473332?l=c9s.blogspot.com' alt='' /></div></content>

前陣子參加 YAPC::Asia，看了 <a href="http://github.com/imakado">imakado</a> demo 的 emacs plugin - <a href="http://github.com/imakado/cpan.el">cpan.el</a> 以及 <a href="http://github.com/imakado/perl-completion">perl-completion.el</a> ，所以我於會後也寫了一個類似的 vim plugin。screencast 可參考此處 (<a href="http://c9s.blogspot.com/2009/09/cpanvim.html">http://c9s.blogspot.com/2009/09/cpanvim.html</a>)<br /><br />寫著寫著覺得可以開發的功能實在很多，於是除了讓 cpan.vim 可以迅速的搜尋 CPAN 模組之外，也支援其他種搜尋模式，如只搜尋 ./lib/ 或是 @INC 或是從 cpan source list 上搜尋。<br /><br />除此之外另外對其他非 Perl 使用者會比較實用的是 ctags search 的功能，要使用此功能必須先安裝 <a href="http://ctags.sourceforge.net/">Exuberant ctags</a> ，來利用 Exuberant Ctags 對各種語言的程式碼來產生 ctags file，目前 <a href="http://ctags.sourceforge.net/languages.html">Exuberant Ctags 支援 41 多種語言</a>。<br /><br />手動產生的方法如下:<br /><br />$ ctags -R foo.c bar.c /path/to/source/<br /><br />這樣便會產生檔案名稱為 tags 的 taglist 檔案於目前目錄下。<br /><br />這是原始的作法。<br /><br />利用 cpan.vim 則只需要使用快捷鍵 Ctrl-C,Ctrl-T 即可開啟 Ctags Search Window，如果找不到 tags 檔案，便會詢問你要產生 ctags 的來源路徑 (支援自動補完路徑 path completion )，然後自動為你產生。<br /><br />鍵入 Pattern 後會自動替你搜尋相關對應的標籤 (tag) ，可用 Ctrl-N , Ctrl-P 來選擇結果，Ctrl-A, Ctrl-E 來跳至行頭、行尾。<br /><br />Enter 則會直接進入該標籤 (tag) , 按下 t 則會將標籤開於新分頁。若該標籤 (tag) 對應到多個檔案，則會跳出選擇清單，只需鍵入編號進入即可。<br /><br />目前唯一的缺點就是當 ctags 檔案非常非常大的時候會有點慢。<br /><br />詳細的使用說明於 README 檔案內。不過我目前還沒有上傳新的版本至 vim.org，我太懶了。(其實是 vim.org 做的實在很簡陋 , sucks)<br /><br />各位使用從 github checkout 最新版本出來即可。<br /><br />Github: <a href="http://github.com/c9s/cpan.vim">http://github.com/c9s/cpan.vim</a><br /><br />或是直接下 git 命令:<br /><br />$ git clone git://github.com/c9s/cpan.vim.git<br /><br />安裝則相當簡易，在 Plugin 目錄下輸入一行命令即可:<br /><br />$ make install<br /><br />其他相關問題歡迎在此篇 Blog 下發問。謝謝。<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-1317896321878513051?l=c9s.blogspot.com' alt='' /></div></content>

當你撰寫任何 Perl 應用程式或是模組，你可能會使用單元測試 (unit test) 來測試你的應用程式是否正確運作。但是測試總是會有遺漏的地方。<br /><br /><a href="http://search.cpan.org/dist/Devel-Cover/">Devel::Cover</a> 模組就是可以幫助你分析測試到的程式碼涵蓋哪些部份，哪些部份總共被執行了幾次，哪些地方沒有被測試到。<br /><br />安裝 Devel::Cover 模組:<br /><code>sudo cpanp i Devel::Cover</code><br /><br />當你 test 都寫好於 t/ 目錄底下，Makefile.PL 也設定好哪些測試目錄底下的測試要被執行。便可先將 Makefile.PL 執行，產生 Makefile.<br /><code>perl Makefile.PL &amp;&amp; make</code><br /><br />接著直接執行 Devel::Cover 所提供的 "cover" script.<br /><code>cover -test</code><br /><br />如此一來就會開始執行測試 (make test) 並且產生報表:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_i3PNCkrh-3k/Sh9WwVYGTgI/AAAAAAAAG4E/NYdNtxX-j8c/s1600-h/Picture+5.png"><img style="cursor: pointer; width: 320px; height: 184px;" src="http://1.bp.blogspot.com/_i3PNCkrh-3k/Sh9WwVYGTgI/AAAAAAAAG4E/NYdNtxX-j8c/s320/Picture+5.png" alt="" id="BLOGGER_PHOTO_ID_5341083071456628226" border="0" /></a><br /><br />另外也會產生 HTML 報表:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_i3PNCkrh-3k/Sh9Wwi0wgoI/AAAAAAAAG4U/gJ0V6XJonCE/s1600-h/Picture+7.png"><img style="cursor: pointer; width: 320px; height: 270px;" src="http://4.bp.blogspot.com/_i3PNCkrh-3k/Sh9Wwi0wgoI/AAAAAAAAG4U/gJ0V6XJonCE/s320/Picture+7.png" alt="" id="BLOGGER_PHOTO_ID_5341083075066495618" border="0" /></a><br />更詳盡的測試分析:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_i3PNCkrh-3k/Sh9Ww86zmiI/AAAAAAAAG4c/9PgRR2HOrbw/s1600-h/Picture+8.png"><img style="cursor: pointer; width: 320px; height: 135px;" src="http://4.bp.blogspot.com/_i3PNCkrh-3k/Sh9Ww86zmiI/AAAAAAAAG4c/9PgRR2HOrbw/s320/Picture+8.png" alt="" id="BLOGGER_PHOTO_ID_5341083082071185954" border="0" /></a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-3229134075518075658?l=c9s.blogspot.com' alt='' /></div></content>

I just wrote a script to install cpan modules inside vim. so that we can move cursor to the module name , and press C-x C-i to install module. :p<br /><br />是一小段可以方便安裝 CPAN 模組的 vim script. 只要把 cursor 移動到 use YAML::Syck; 之類的 YAML 字樣上方，然後按下 C-x C-i 就會安裝 YAML::Syck 模組。<br /><br />對於 python 或是 ruby 的朋友可以把對 CWORD 的 regular expression 和 command 換一下，應該就可以用了。<br /><script src="http://gist.github.com/119172.js"></script><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3147036244016021082-2149779716247023722?l=c9s.blogspot.com' alt='' /></div></content>
