Re: [ jEdit-devel ] Elastic tabstops is completely broken

Hi,
Please see my comments below :
Problem #2
This is not a bug.
Elastic tabstops align multiple tabs (in a line) in column blocks of uniform
width such that each line in a column block ends with a tab character.Please
see below :
/t signifies a tab character
Column1 Column 2 Column
3 Column 4
Line 1 : /t int firstVar= /t 1 ;
/t //This is the first variable
Line 2: /t String secondString= /t "Hello World" ;
/t //This is the second variable
Line 3: /t String thirdString= /t "Hi There!"
;/t //This is the third variable
Line 4: /t String fourthString= /t "I am working on
jedit";/t //This is the fourth variable
Now if the text in second and third line of third column is deleted (this
is similar to scenario of problem #2) the alignment doesnt change as the
alignment depends on column blocks which are controlled solely by tabs .
Column1 Column 2 Column
3 Column 4
Line 1 : /t int firstVar= /t 1 ;
/t //This is the first variable
Line 2: /t String secondString= /t
/t //This is the second variable
Line 3: /t String thirdString= /t
/t //This is the third variable
Line 4: /t String fourthString= /t "I am working on
jedit";/t //This is the fourth variable
Problem #1
This is a known limitation of elastic tabstops and is related to Problem #2.
Please see "Mixing indentation and alignment" in
http://tibleiz.net/code-browser/elastic-tabstops.html
Basically if the number of tabs in a particular line get reduced (due to
removal of indentation) the alignment of the whole ColumnBlock changes .So
if tab at Line 1 Column 1 above gets deleted the alignment of all four lines
change as the width of Column 1 increases now.
Column1 Column 2 Column
3 Column 4
Line 1 : int firstVar= /t 1 ; /t //This
is the first variable
Line 2: /t String secondString= /t "Hello World"
; /t //This is the second variable
Line 3: /t String thirdString= /t "Hi There!"
;/t //This is the third variable
Line 4: /t String fourthString= /t "I am
working on jedit";/t //This is the fourth variable
Space Problem:
The space between two columns in elastic tab stops = Tab Width set by the
user in Global Options >Editing

Anshal
