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。
配置成简单好用的c/java代码编辑器
1、缩进与tab
(1)Options菜单àPreferencesàTyping卡,勾掉下面两项∶
Typing tab indents line,regardless 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
(2)Options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)
(3)Options菜单àDocument Optionsà选择合适的文件类型à点击右边中间的Auto Indent钮à在弹出的框中,左边一定要点Smart,右边有两个复选框Indent Open Brace和Indent Close Brace,具体效果可以看SIS的HELP。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 Indent之SMART的效果∶在C程序里, 如果遇到行末没有分号的语句,如IF, WHILE, SWITCH等, 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 Brace和Indent 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PROJECT并ADD 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和.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DOS的EDIT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里*.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 àTyping卡àAuto 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.用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OK,SIS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为 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∶
Old Name 填旧名称。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。 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
3.1在SourceInsight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 “(”和 “)”、把正则表达式分割成不同的组;模式中的每个组自左向右指定为 Group #n,n=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:tc,tc源文件放在d:tcsrc下,并命名为qn.c或qtn.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_HOME是c:jdk,我的java源文件放于d:javasrc中,并命名为qn.java或qtn.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 First、SIS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 Done、SIS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>
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.
