[BZ#671607] Support command line text filters
Submitted by Adam Russell
Link to original bug (#671607)
Description
I often times find myself wishing meld supported more command line options similar to diff, especially regarding ignoring whitespace. It is inconvenient to have to start meld, manually check/uncheck the text filters I want in the preferences, and then restart meld with the actual diff I desire. Instead, I'd rather just be able to pass in options to meld in a similar fashion to diff, e.g.:
-i, --ignore-case
ignore case differences in file contents
-E, --ignore-tab-expansion
ignore changes due to tab expansion
-b, --ignore-space-change
ignore changes in the amount of white space
-w, --ignore-all-space
ignore all white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-I, --ignore-matching-lines=RE
ignore changes whose lines all match RE
