It makes it easier to traverse directories in the command line.
goto is essentially an alias for cd with greater functionality, and complementary functions.
There are two lists and each has respective commands for traversing within the lists:
- "unique list" - a list of unique directories that have been visited using goto
- "history list" - an ordered list reflecting directory traversal using goto
When traversing with goto the content of both of these lists is changed.
When traversing with commands specific to a list, that list is modified e.g. history commands only affect the history list.
cd and related commands do not modify either list.
Source forward_back into your environment.
This command affects both directory lists.
goto - show list of indexed directories
goto $1 - when $1 is a number prefixed with - cd to directory on unique list with that index
when $1 is a directory, attempt to cd to that directory.
When $1 is - cd -
These commands only affect the unique list.
drop - remove all directories from list except current directory
drop $1 - remove directory with index $1 from list
up - cd to previous item in the list
down - cd to next item in the list
These commands only affect the history list.
back - cd to previous item in list.
forward - cd to next item in the list.
If you have identifier conflicts see the top of the file. Aliases are very easily modified to suit a user's needs.
Set _GOTO_UPDATE_HISTORY to a non-empty string to cause list commands to update history.
Set _GOTO_IGNORE_CMDS to an empty string to cause forward_back commands to be saved in bash command history.
-
Creates some temporary directories to perform tests.
-
For each test:
- re-source in ./forward_back
- run a function
- test side effects
-
setup ()- reset for each test and describe function that's being tested -
expect_equal ()- value that is being tested, get said value, is said value-eq $3?- if false exit
- if true continue with tests
