tcl - How to join without losing special characters? -

-

i have following string:

"name\r {} {} {} {} {} other_name other_name {} {} -600.0 {} {} 860.0 {} {} -"

(i.e. string special character: \r ).

when join line lose special charecters.

suppose:

set name "name\r {} {} {} {} {} other_name other_name {} {} -600.0 {} {} 860.0 {} {} -"  set name [join $name]

now name losing special characters(at least \r).

how resolve this?

i tried few things , came this:

set name {name\r {} {} {} {} {} other_name other_name {} {} -600.0 {} {} 860.0 {} {} -} # braces prevent substitution of \r  regsub -all {\\r} $name {\\\r} name # substitution using regexp substitute \r \\r  set name [join $name] # returns: "name\r      other_name other_name   -600.0   860.0   -"

or in case there might more characters might want escape, use more general:

regsub -all {\\} $name {\\\\} name

instead.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
