bug#64964: [PATCH] Handle tabs in the SQL shown in the column listing

[john muhl]

Tags: patch

In sqlite-mode if the SQL used to create a column used tabs then the
hide part of list columns would not remove anything after the first tab.

M-x sqlite-mode-open-file my.db

Table Name      Number of Rows  
images                        0 
users                         0

With point on ‘images’ execute sqlite-mode-list-columns (or press c)

Table Name      Number of Rows  
images                        0 
  id INTEGER PRIMARY KEY AUTOINCREMENT
  user_id INTEGER
  FOREIGN KEY (user_id) REFERENCES users (id)
                ON DELETE CASCADE
users                         0

There are two tab characters before ‘ON DELETE’. Press c again and it
collapses to:

Table Name      Number of Rows  
images                        0 
                ON DELETE CASCADE
users                         0
