Miscellaneous techniques

• Techniques discussed
• Breadcrumbs
• Navigation by line number
• Continuous scrolling

Breadcrumbs

• Similar to Back/Forward buttons in a browser
• Certain commands automatically drop breadcrumbs
• Can use commands to move forward/backward through
  the trail of breadcrumbs

Breadcrumbs Example
For ( )
Test.cpp
breadcrumb inserted here
Vector aVector Vector retVector new
Vector() if( right ! NULL ) aVector
right-gtlistIndexesInOrder() retVector-gtadd(aVec
tor) delete aVector retVector-gtadd(docInd
ex) if( left ! NULL ) aVectorleft-gtlistIn
dexesInOrder() retVector-gtadd(aVector)
search forward for get cited by

Breadcrumbs Example

For ( )
Test.cpp
other crumb here
DocList DocumentgetCitedBy(mode
aMode) char temp256 fstream blank
hotList if( children NULL ) // call get
URL if( !getDocumentsCitedBy(hotList,
identifier) ) cout ltlt "CITEDBY " ltlt
identifier ltlt
" (primitive error)"
find again

Moved forward again
DocList DocumentgetCitedBy(mode
aMode) char temp256 fstream blank
hotList if( children NULL ) // call get
URL if( !getDocumentsCitedBy(hotList,
identifier) ) cout ltlt "CITEDBY " ltlt
identifier ltlt
" (primitive error)"

Navigate by line number

• Kudos to Jonathan Epstein
• Identify a target position by giving a line
  number and a particular landmark on that line
• Landmark can be
• punctuation mark
• symbol
• character
• etc...

10
Navigate by line number Example
For ( )
Test.cpp
132 DocList DocumentgetCitedBy(mode
aMode) 133 134 char temp256 135 fstream
blank hotList 136 if ( children NULL
) 137 138 // call get URL 139 if(
!getDocumentsCitedBy(hotList, identifier) )
140 140 141 142 cout ltlt "CITEDBY " ltlt
identifier ltlt 143
" (primitive error)"
go to paren on 36

Test.cpp
breadcrumb here
132 DocList DocumentgetCitedBy(mode
aMode) 133 134 char temp256 135 fstream
blank hotList 136 if ( children NULL
) 137 138 // call get URL 139 if(
!getDocumentsCitedBy(hotList, identifier) )
140 140 141 142 cout ltlt "CITEDBY " ltlt
identifier ltlt 143
" (primitive error)"
move cursor here
12
Continuous scrolling

• Kudos to Jonathan Epstein
• Similar to Dragon Move left/right/up/down macro
• Tell cursor to move in a certain way
• Cursor keeps scrolling until you ask it to stop
• Can change direction and/or speed of movement
• But, cursor may move by more than one line or
  character at a time

13
Continuous scrolling Example
For ( )
Test.cpp
Vector aVector Vector retVector new
Vector() if( right ! NULL ) aVector
right-gtlistIndexesInOrder() retVector-gtadd(aVec
tor) delete aVector retVector-gtadd(docInd
ex) if( left ! NULL ) aVectorleft-gtlistIn
dexesInOrder() retVector-gtadd(aVector)
keep searching for a vector

Vector() if( right ! NULL ) aVector
right-gtlistIndexesInOrder() retVector-gtadd(aVec
tor) delete aVector retVector-gtadd(docInd
ex) if( left ! NULL ) aVectorleft-gtlistIn
dexesInOrder() retVector-gtadd(aVector)
move here...

Continuous scrolling

• Similar functionalities for
• paging up/down
• moving up/down one block of code at a time
• moving up/down one function/class at a time
• looping through open files
• etc...
