sourceinsight使用技巧

sourceinsight使用技巧
1 sourceinsight screen font 的默认字体是Verdana的,它是一直变宽字体。在Document style中可以将字体改为定宽的Courier

2 勾掉indent Open Brace和Indent Close Brace的效果: 继上一段,在相对缩进行里, 如果输入"{"或"}", 则自动和上一行列对齐

3 今天把一个用sourceinsight排版整齐的C文件,偶然用VC打开一看,全乱了。研究了半天,发现SI对每个字符的宽度不太一致。发现选上"view --> draft view", 就可以让每个字符的宽度一致了。快捷键是 "Alt + F12"

4 选中几行代码按tab键或者shift+tab可以左右移动代码,调整代码时很有用。

配置成简单好用的c/java代码编辑器

1、缩进与tab

1Options菜单àPreferencesàTyping卡,勾掉下面两项∶

Typing tab indents lineregardless of selection,空行按tab无法前进

Typing tab replaces current selection,选定部分内容、再按tab时会清除所选

2Options菜单àDocument Options(针对不同文件类型,分别进行设置)à下拉左上文件类型框、选择合适类型(c源文件)àEditing Options框中,tab width=2à Editing Options框中,勾选Expand tabs(这样,按tab键、等价于输入2个空格)

3Options菜单àDocument Optionsà选择合适的文件类型à点击右边中间的Auto Indentà在弹出的框中,左边一定要点Smart,右边有两个复选框Indent Open BraceIndent Close Brace,具体效果可以看SISHELP。按照部门里的编程风格要求,最方便的就是把两个复选框都取消掉,然后点OK

勾选Auto IndentSMART的效果∶在C程序里, 如果遇到行末没有分号的语句,IF, WHILE, SWITCH, 写到该行末按回车,则新行自动相对上一行缩进两列。

勾掉Indent Open BraceIndent Close Brace的效果∶继上一段,在相对缩进行里, 如果输入"}", 则自动和上一行列对齐(好像勾不勾都会有这个功能);而输入"{"时,不会与下面的行对齐(这是勾上Indent Open Brace时的效果)。

2、向项目中添加文件时,只添加特定类型的文件(文件类型过滤器)

有个同事比较生猛,得整汇编代码,但在SIS里建立PROJECTADD TREE的时候,根据默认设置并不会把该TREE里面所有汇编文件都包含进来,只加了.inc.asm后缀的,.s后缀的没有。而且用SIS打开.s的文件,一片黑白没有色彩,感觉回到DOSEDIT时代了…… 解决方法是在Options->Document Options里面,点左上的Document Type下拉菜单,选择x86 Asm Source File,然后在右边的File filter*.asm*.inc的后面加上*.s;接着CLOSE就可以了。上面两个问题解决了,但注意加入*.s后还需要重新ADD TREE一遍才能把这些汇编加到PROJECT里面。

3、去掉功能强大但是无用的自动完成功能

Options菜单àPreferences àTypingàAuto Completion框,勾掉Use automatic symbol completion window(这里是SIS的全局设置)

Options菜单àDocument OptionsàEditing Options框中,勾掉Allow auto-complete(局部设置)

上面两项必须全部勾选,才能启用Auto Completion功能

4、恢复小键盘的“+-*/”功能

Options菜单àKey assignments,通过关键词Scroll 找到Scroll Half Page Up,取消小键盘/;通过关键词Scroll 找到Scroll Half Page Down取消小键盘*;通过关键词Function找到Function Up,取消小键盘-,通过关键词Function找到Function down,取消小键盘+

5、恢复ctrl+a的全选功能

通过关键词save 找到save all,更改为ctrl+shift+a,通过关键词select找到select all 更改为ctrl +a

6、解决字符等宽对齐问题。

SIS默认字体是VERDANA,很漂亮。这网页上应该也是用的VERDANA字体。但由于美观的缘故,VERDANA字体是不等宽的。比如下面两行

llllllllll

MMMMMMMMMM

同样10个字符,长度差多了.VERDANA来看程序,有些本应该对齐的就歪了。解放方法是使用等宽的字体,但肯定比较丑。可以用DOS字体,也就是记事本里的默认字体sysfixed 很丑,要有心理准备。比较推荐的是用Courier New

SourceInsight提供的功能

1、解析日志信息时非常有用的Source Link

总地说来,SourceLink根据特定的搜索模式,把当前文件中满足模式的行、链接到由该行指定的其他源文件中。

所谓特定的搜索模式,共有两种“File, then line”和“Line, then file”,其中前后两部分依靠正则表达式的组的概念来予以分割。如果当前文件具有匹配行,比如“Error d:tcsrcq5.c 18: Lvalue required in function jsSort”,那么SourceInsight在该行创建SourceLink、把该行链接到由该行指定的文件中(即d:tcsrcq5.c,第18行)。

1.1 创建SourceLink

运行Search菜单的Parse Source Links…命令,在弹出的框中、选择搜索模式、并填入相应的正则表达式串,点OKSIS就会解析当前文件,如果有匹配,就创建SourceLink

1.2 在解析日志信息时,使用SourceLink

可以打开日志信息,运行Parse Source Links命令,日志中能够匹配模式的每一行(通常是含有错误信息的行)、就会被设置上一个SourceLink

1.3在解析自定义命令输出时,使用SourceLink

首先勾选Custom Command 中的“Parse Links in Output”,然后选择特定的搜索模式,最后填入合适的正则表达式。这样,Source Insight把输出信息作为当前搜索用文件;并且,如果有匹配行(通常即编译错误信息行),SIS 该行创建SourceLink、并把每一个错误信息中给定的文件(和行号)作为link目的地,这对于我们修改源代码错误非常有帮助。

2、替换(Replace VS 上下文敏感的智能重命名(Context-Sensitive Smart Rename

2.1 替换(Replace

目前来说,普通的替换命令、快捷键为ctrl+H,足以已满足工作要求。

在弹出的替换窗口中,在Search框中勾选Selection来只在所选文本区域中替换(当然这时你要先选定区域然后再按ctrl+H)、勾选WholeFile来在整个当前文件内替换、两者都不勾选来从当前光标处替换至文件末尾;点右边的Files…按钮,可选择替换多个文件的内容。

2.2上下文敏感的智能重命名(Context-Sensitive Smart Rename

Smart Rename命令、快捷键是Ctrl+’,是上下文敏感的全局搜索替换。它可以智能地重命名全部项目文件中的一个标示符。SourceInsight的搜索索引(search index)使得搜索过程进行地非常快。而且,使用Smart Rename所做的替换会被记录在Search Results窗口中,每一条替换记录旁有一个SourceLink链接到替换发生地文件。

Smart Rename可以用来重命名标记(symbol)。如果勾选了Smart Reference Matching选项,Smart Rename就只在正确的上下文范围内进行重命名。它可以智能地重命名全部项目文件中的一个标示符;它可以重命名函数本地变量,类或结构体成员、函数。

在弹出的Smart Rename窗口中有下面几项∶

旧名称。光标下的词会被自动加载;光标的位置非常重要,这是因为Source Insight会根据本地上下文背景、准确地确定你想要重命名哪一个标记。<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

推荐只填单个词、而不是字符串。

如果你在命名成员变量、或本地变量(),Old Name框中会显示完全标记名、即上层容器名+标记名。例如,框中的“DocDraw.paintStruc”代表DocDraw是函数名,paintStruc是函数的本地成员变量。

New Name 填新名称。只填标记名,不填上层容器名。

Output Search Results 如果勾选,搜索替换结果日志会被输出到Search Results窗口中。可以通过Windows菜单来切换,或ctrl+tab切换察看。并且每一条记录旁会有SourceLink链接到替换发生地文件。

Confirm Each Replacement 每次替换询问。

Skip Comments 不重名注释部分。

 

【使用心得列表】

(1)如何用Smart Rename重命名数组的数组名?如果只选取数组名,会报错!

(2)如果勾掉Smart Reference Matching,会搜索全部项目文件,并且Old Name框中不显示完全限定名;如果勾选Smart Reference Matching,无法重命名数组名,而且鼠标位置不正确时会报错。应该如何应对?

3、在SourceInsight中提供的正则表达式

3.1SourceInsight中提供的正则表达式

正则表达式,是用来匹配复杂模式的特殊搜索用字符串。正则表达式串中,许多字符具有特殊的含义。例如,有个特殊的字符代表 行首

下面是SourceInsight提供的所有可用特殊字符∶

Table 4.3: Regular Expression Characters

Character

Matches

^ (at the beginning only)

beginning of line。如^Hello,匹配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$,匹配TRUE在句尾。

转义字符。如果在它后面有元字符,取消其特殊含义。

 

可利用 “(” “)”、把正则表达式分割成不同的;模式中的每个组自左向右指定为 Group #nn=1,2,…组的概念在替换时很有用。

例如∶

abc(xyz)可匹配abcxyz,其中xyz被认为是group#1

利用21来替换(abc)(xyz),替换结果为xyzabc

3.2 正则表达式在配置tc编译器中的应用∶

正则表达式格式与源代码文件路径相对应,这里我的tc安装目录为d:tctc源文件放在d:tcsrc下,并命名为qn.cqtn.c(其中n=1,2,…)。

观察Tc编译器某一次输出错误信息的格式∶

Error d:tcsrcq5.c 18: Lvalue required in function jsSort

则我们要匹配“d:tcsrcq5.c 18”部分,进一步地,按照SourceInsight捕捉输出并加以解析时的要求,要以组的形式、分别匹配“d:tcsrcq5.c 18”中的文件部分和行号部分∶

行号([1-9][0-9]*)

空格行号s([1-9][0-9]*)

文件名(d:tcsrc[qQ][tT][1-9][0-9]*.[cC])

全部加起来为∶

(d:tcsrc[qQ][tT]*[1-9][0-9]*.[cC])s([1-9][0-9]*)

 

3.3 正则表达式在配置javac编译器中的应用∶

我的JAVA_HOMEc:jdk,我的java源文件放于d:javasrc中,并命名为qn.javaqtn.java(其中n=1,2,…)。

观察JDK编译器某一次输出错误信息的格式∶

D:javasrcQ3.java:3: ';' expected

正则表达式为∶

([dD]:javasrc[qQ][tT]*[1-9][0-9]*.java):([1-9][0-9]*)

 

4、自定义命令

自定义命令与项目相关,在一个项目中定义的所有自定义命令属于该项目、只对该项目有效(包括快捷键等)。

自定义命令类似于命令行批处理文件。SIS允许自定义命令在后台运行;并可以捕捉自定义命令的输出、放置于文件中、或粘贴入当前光标插入点。

分别利用上面SIS对输出信息的处理方式,自定义命令对集成编译器相当有用,可以捕捉编译器输出并创建SourceLink寻错;自定义命令对于文本过滤也相当有用,可选中待过滤区块、运行Sort自定义命令、粘贴回选定区块、即完成文本过滤。

请按下面步骤创建自定义命令∶

Options菜单àCustom Command

à点右边Add钮、填入新自定义命令名称,或下拉左边Commands、选择命令进行修改

àRun框、填入待执行命令行,可含有特殊元字符,见后面的元字符表

àDir框、执行命令行时应处的目录,如不填,以源代码文件所在目录为命令执行目录

à勾选Output框的Capture Output、输出被捕捉,如果勾选Paste Output,输出被粘贴

à勾选Control Group框中的Save Files FirstSIS会在运行命令前先检查文件是否保存

à勾选Control Group框中的Pause When DoneSIS会在命令结束后暂停、方便检查

à勾选Source Links in Output框中的Parse Source Links,?/p>

5使用最强大的宏功能,真的达到的完美境界

说明:
    该宏文件实现一些编码程中能会到的功能, 如添加文件头、函数说明和宏定义等, 使用时能自动添加文件名、函数名和当前日期.

使用说明:
    1. Project->Open Project... 打开Base工程(该工程一般在"我的文档\Source Insight\Projects\Base"中);
    2. Project->Add and Remove Project Files... 加入宏文件(即mymacro.em);
    3. Options->Menu Assignments 打开Menu Assignments窗口, 在Command中输入Macro, 选中要使用的宏, 添加到合适的菜单中.
http://www.sourceinsight.com/public/macros/可以找到很多宏定义文件,但大多数没什么用。
/*附上宏定义文件(一下是我精心挑选的十分好用的宏定义,不试不知道,一试真有用)*/
/* mymacro.em - a small collection of useful editing macros */

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.
