<b>sourceinsight使用技巧</b>
1 sourceinsight screen font 的預設字型是Verdana的,它是一直變寬字型。在Document style中可以将字型改為定寬的Courier
2 勾掉indent Open Brace和Indent Close Brace的效果: 繼上一段,在相對縮進行裡, 如果輸入"{"或"}", 則自動和上一行列對齊
3 今天把一個用sourceinsight排版整齊的C檔案,偶然用VC打開一看,全亂了。研究了半天,發現SI對每個字元的寬度不太一緻。發現選上"view --> draft view", 就可以讓每個字元的寬度一緻了。快捷鍵是 "Alt + F12"
4 選中幾行代碼按tab鍵或者shift+tab可以左右移動代碼,調整代碼時很有用。
(1)Options菜單àPreferencesàTyping卡,勾掉下面兩項∶
Typing tab indents line,regardless of selection,空行按tab無法前進
Typing tab replaces current selection,標明部分内容、再按tab時會清除所選
(2)Options菜單àDocument Options(針對不同檔案類型,分别進行設定)à下拉左上檔案類型框、選擇合适類型(c源檔案)àEditing Options框中,tab width=2à Editing Options框中,勾選Expand tabs(這樣,按tab鍵、等價于輸入2個空格)
(3)Options菜單àDocument Optionsà選擇合适的檔案類型à點選右邊中間的Auto Indent鈕à在彈出的框中,左邊一定要點Smart,右邊有兩個複選框Indent Open Brace和Indent Close Brace,具體效果可以看SIS的HELP。按照部門裡的程式設計風格要求,最友善的就是把兩個複選框都取消掉,然後點OK。
勾選Auto Indent之SMART的效果∶在C程式裡, 如果遇到行末沒有分号的語句,如IF, WHILE, SWITCH等, 寫到該行末按回車,則新行自動相對上一行縮進兩列。
勾掉Indent Open Brace和Indent Close Brace的效果∶繼上一段,在相對縮進行裡, 如果輸入"}", 則自動和上一行列對齊(好像勾不勾都會有這個功能);而輸入"{"時,不會與下面的行對齊(這是勾上Indent Open Brace時的效果)。
有個同僚比較生猛,得整彙編代碼,但在SIS裡建立PROJECT并ADD TREE的時候,根據預設設定并不會把該TREE裡面所有彙編檔案都包含進來,隻加了.inc和.asm字尾的,.s字尾的沒有。而且用SIS打開.s的檔案,一片黑白沒有色彩,感覺回到DOS的EDIT時代了…… 解決方法是在Options->Document Options裡面,點左上的Document Type下拉菜單,選擇x86 Asm Source File,然後在右邊的File filter裡*.asm;*.inc;的後面加上*.s;接着CLOSE就可以了。上面兩個問題解決了,但注意加入*.s後還需要重新ADD TREE一遍才能把這些彙編加到PROJECT裡面。
Options菜單àPreferences àTyping卡àAuto Completion框,勾掉Use automatic symbol completion window(這裡是SIS的全局設定)
Options菜單àDocument OptionsàEditing Options框中,勾掉Allow auto-complete(局部設定)
上面兩項必須全部勾選,才能啟用Auto Completion功能
Options菜單àKey assignments,通過關鍵詞Scroll 找到Scroll Half Page Up,取消小鍵盤/;通過關鍵詞Scroll 找到Scroll Half Page Down取消小鍵盤*;通過關鍵詞Function找到Function Up,取消小鍵盤-,通過關鍵詞Function找到Function down,取消小鍵盤+。
通過關鍵詞save 找到save all,更改為ctrl+shift+a,通過關鍵詞select找到select all, 更改為ctrl +a
SIS預設字型是VERDANA,很漂亮。這網頁上應該也是用的VERDANA字型。但由于美觀的緣故,VERDANA字型是不等寬的。比如下面兩行
llllllllll
MMMMMMMMMM
同樣10個字元,長度差多了.用VERDANA來看程式,有些本應該對齊的就歪了。解放方法是使用等寬的字型,但肯定比較醜。可以用DOS字型,也就是記事本裡的預設字型sysfixed 很醜,要有心理準備。比較推薦的是用Courier New。
總地說來,SourceLink根據特定的搜尋模式,把目前檔案中滿足模式的行、連結到由該行指定的其他源檔案中。
所謂特定的搜尋模式,共有兩種“File, then line”和“Line, then file”,其中前後兩部分依靠正規表達式的組的概念來予以分割。如果目前檔案具有比對行,比如“Error d:tcsrcq5.c 18: Lvalue required in function jsSort”,那麼SourceInsight在該行建立SourceLink、把該行連結到由該行指定的檔案中(即d:tcsrcq5.c,第18行)。
運作Search菜單的Parse Source Links…指令,在彈出的框中、選擇搜尋模式、并填入相應的正規表達式串,點OK,SIS就會解析目前檔案,如果有比對,就建立SourceLink。
可以打開日志資訊,運作Parse Source Links指令,日志中能夠比對模式的每一行(通常是含有錯誤資訊的行)、就會被設定上一個SourceLink
首先勾選Custom Command 中的“Parse Links in Output”,然後選擇特定的搜尋模式,最後填入合适的正規表達式。這樣,Source Insight把輸出資訊作為目前搜尋用檔案;并且,如果有比對行(通常即編譯錯誤資訊行),SIS為 該行建立SourceLink、并把每一個錯誤資訊中給定的檔案(和行号)作為link目的地,這對于我們修改源代碼錯誤非常有幫助。
目前來說,普通的替換指令、快捷鍵為ctrl+H,足以已滿足工作要求。
在彈出的替換視窗中,在Search框中勾選Selection來隻在所選文本區域中替換(當然這時你要先標明區域然後再按ctrl+H)、勾選WholeFile來在整個目前檔案内替換、兩者都不勾選來從目前光标處替換至檔案末尾;點右邊的Files…按鈕,可選擇替換多個檔案的内容。
Smart Rename指令、快捷鍵是Ctrl+’,是上下文敏感的全局搜尋替換。它可以智能地重命名全部項目檔案中的一個标示符。SourceInsight的搜尋索引(search index)使得搜尋過程進行地非常快。而且,使用Smart Rename所做的替換會被記錄在Search Results視窗中,每一條替換記錄旁有一個SourceLink連結到替換發生地檔案。
Smart Rename可以用來重命名标記(symbol)。如果勾選了Smart Reference Matching選項,Smart Rename就隻在正确的上下文範圍内進行重命名。它可以智能地重命名全部項目檔案中的一個标示符;它可以重命名函數本地變量,類或結構體成員、函數。
在彈出的Smart Rename視窗中有下面幾項∶
舊名稱。光标下的詞會被自動加載;光标的位置非常重要,這是因為Source Insight會根據本地上下文背景、準确地确定你想要重命名哪一個标記。<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
推薦隻填單個詞、而不是字元串。
如果你在命名成員變量、或本地變量(),Old Name框中會顯示完全标記名、即上層容器名+标記名。例如,框中的“DocDraw.paintStruc”代表DocDraw是函數名,paintStruc是函數的本地成員變量。
New Name 填新名稱。隻填标記名,不填上層容器名。
Output Search Results 如果勾選,搜尋替換結果日志會被輸出到Search Results視窗中。可以通過Windows菜單來切換,或ctrl+tab切換察看。并且每一條記錄旁會有SourceLink連結到替換發生地檔案。
Confirm Each Replacement 每次替換詢問。
Skip Comments 不重名注釋部分。
【使用心得清單】
(1)如何用Smart Rename重命名數組的數組名?如果隻選取數組名,會報錯!
(2)如果勾掉Smart Reference Matching,會搜尋全部項目檔案,并且Old Name框中不顯示完全限定名;如果勾選Smart Reference Matching,無法重命名數組名,而且滑鼠位置不正确時會報錯。應該如何應對?
正規表達式,是用來比對複雜模式的特殊搜尋用字元串。正規表達式串中,許多字元具有特殊的含義。例如,有個特殊的字元代表 “行首”。
下面是SourceInsight提供的所有可用特殊字元∶
Table 4.3: Regular Expression Characters
Character
Matches
^ (at the beginning only)
beginning of line。如^Hello,比對Hello在句首。
.
any single character
[abc]
any single character that belongs to the set abc
[^abc]
any single character that does not belong to the set abc
*
zero or more occurrences of the preceding character
+
one or more occurrences of the preceding character
t
a tab character
s
a space character
w
white space (a tab or a space character)
$
the end of the line。如TRUE$,比對TRUE在句尾。
轉義字元。如果在它後面有元字元,取消其特殊含義。
可利用 “(”和 “)”、把正規表達式分割成不同的組;模式中的每個組自左向右指定為 Group #n,n=1,2,…;組的概念在替換時很有用。
例如∶
abc(xyz)可比對abcxyz,其中xyz被認為是group#1,
利用21來替換(abc)(xyz),替換結果為xyzabc。
正規表達式格式與源代碼檔案路徑相對應,這裡我的tc安裝目錄為d:tc,tc源檔案放在d:tcsrc下,并命名為qn.c或qtn.c(其中n=1,2,…)。
觀察Tc編譯器某一次輸出錯誤資訊的格式∶
Error d:tcsrcq5.c 18: Lvalue required in function jsSort
則我們要比對“d:tcsrcq5.c 18”部分,進一步地,按照SourceInsight捕捉輸出并加以解析時的要求,要以組的形式、分别比對“d:tcsrcq5.c 18”中的檔案部分和行号部分∶
行号([1-9][0-9]*)
空格行号s([1-9][0-9]*)
檔案名(d:tcsrc[qQ][tT][1-9][0-9]*.[cC])
全部加起來為∶
(d:tcsrc[qQ][tT]*[1-9][0-9]*.[cC])s([1-9][0-9]*)
我的JAVA_HOME是c:jdk,我的java源檔案放于d:javasrc中,并命名為qn.java或qtn.java(其中n=1,2,…)。
觀察JDK編譯器某一次輸出錯誤資訊的格式∶
D:javasrcQ3.java:3: ';' expected
正規表達式為∶
([dD]:javasrc[qQ][tT]*[1-9][0-9]*.java):([1-9][0-9]*)
自定義指令與項目相關,在一個項目中定義的所有自定義指令屬于該項目、隻對該項目有效(包括快捷鍵等)。
自定義指令類似于指令行批處理檔案。SIS允許自定義指令在背景運作;并可以捕捉自定義指令的輸出、放置于檔案中、或粘貼入目前光标插入點。
分别利用上面SIS對輸出資訊的處理方式,自定義指令對內建編譯器相當有用,可以捕捉編譯器輸出并建立SourceLink尋錯;自定義指令對于文本過濾也相當有用,可選中待過濾區塊、運作Sort自定義指令、粘貼回標明區塊、即完成文本過濾。
請按下面步驟建立自定義指令∶
Options菜單àCustom Command
à點右邊Add鈕、填入新自定義指令名稱,或下拉左邊Commands、選擇指令進行修改
àRun框、填入待執行指令行,可含有特殊元字元,見後面的元字元表
àDir框、執行指令行時應處的目錄,如不填,以源代碼檔案所在目錄為指令執行目錄
à勾選Output框的Capture Output、輸出被捕捉,如果勾選Paste Output,輸出被粘貼
à勾選Control Group框中的Save Files First、SIS會在運作指令前先檢查檔案是否儲存
à勾選Control Group框中的Pause When Done、SIS會在指令結束後暫停、友善檢查
à勾選Source Links in Output框中的Parse Source Links,?/p>
5使用最強大的宏功能,真的達到的完美境界
說明:
該宏檔案實作一些編碼程中能會到的功能, 如添加檔案頭、函數說明和宏定義等, 使用時能自動添加檔案名、函數名和目前日期.
使用說明:
1. Project->Open Project... 打開Base工程(該工程一般在"我的檔案\Source Insight\Projects\Base"中);
2. Project->Add and Remove Project Files... 加入宏檔案(即mymacro.em);
3. Options->Menu Assignments 打開Menu Assignments視窗, 在Command中輸入Macro, 選中要使用的宏, 添加到合适的菜單中.
/*附上宏定義檔案(一下是我精心挑選的十分好用的宏定義,不試不知道,一試真有用)*/
/* mymacro.em - a small collection of useful editing macros */

1. Add this file to your project or your Base project.
2. Run the Options->Key Assignments command and assign a
convenient keystroke to the "AutoExpand" command.
3. After typing a keyword, press the AutoExpand keystroke to have the
statement expanded. The expanded statement will contain a ### string
which represents a field where you are supposed to type more.
The ### string is also loaded in to the search pattern so you can
use "Search Forward" to select the next ### field.
For example:
1. you type "for" + AutoExpand key
2. this is inserted:
for (###; ###; ###)
{
###
}
3. and the first ### field is selected.
