* Tests: Add coverage for del / move without -f, but with prompting
Supplying the user confirmation via "yes".
* Cosmetics: Align inconsistent spacing for before (y/n) prompt
* Refactoring: Extract confirm() function
The user confirmation query had been duplicated (once) in the code.
* Refactoring: confirm(): Leave early if forced
* Return from user prompt without requiring Enter
By just reading a single character (y for yes, anything else: no).
* Tests: Ensure that only a single "y" concludes the confirmation
By switching from "yes" (that endlessly prints newline-separated "y"s) to "printf y".
* t1800-del: Add coverage for negative confirmation
Negative means "anything but y", so "n", "x", and Enter all apply.
* Cosmetics: Add trailing space after (y/n) prompt
So that the user's typed answer is not recorded directly after it, but with separation: "Foo? (y/n) y" instead of "Foo? (y/n)y".
*Compatibility: "read -N 1" is only available in Bash 4.1+
Mac OS still ships with Bash 3.2 :-( Fall back to the original prompting that requires conclusion via Enter then.
Note: Even though the tests use "printf y", this still gets accepted, as there'll be EOF after that. In real use (when stdin from the terminal stays open), a concluding Enter is mandatory, though.
Closes#152
Before adding any more features to todo_completion, I feel like I need test coverage, so this is a first stab at testing the completion results, via a new test function test_todo_completion.
Some basic tests showcase the capabilities.
Note: test-lib.sh now uses arrays, therefore all tests must use /bin/bash, not /bin/sh to avoid errors when sourcing test-lib. For consistency with todo.sh, we should have used Bash everywhere, anyway. Also note that t2000-multiline.sh needs some more quoting to avoid "Bash: ambiguous redirect" errors.
I.e. removed the colon after the ITEM#. Updated tasks are now listed like the 'todo.sh ls' command does, e.g.
42 smell the roses
This is in preparation to eventually use a function factored out from _list() for the verbose task output, which would enable coloring in the verbose message and thus align the verbose message output even more with the normal task output.
- Condensing whitespace around TERM into a single space and removing leading/trailing spaces if at the beginning/end of the task.
- Proper error message if TERM not found.
- Aligned verbose removal message with the verbose output of the 'replace' command.
In addition, removed (accidental) printing of the task (without leading ITEM#) when checking for existence of the task; using empty check of task text as done elsewhere.
