To indicate that something went wrong (e.g. the task already was unprioritized).
Note: For actions that handle multiple ITEMs in a loop, we cannot use die() as that would abort processing of any following ITEM(s). Instead, use a status variable and set it to 1 on error, then exit at the end.
I've seen strange readline editing behavior when the editing doesn't start at the first column: I can actually backspace into the prepended message (with Del, Ctrl-W or Ctrl-U), and then the whole edit becomes messed up.
read can output a prompt on its own (hopefully in all versions of Bash that we aim to support - the tests will tell), and that doesn't have this problem, and it's also a bit cleaner and shorter.
The prompt is only displayed if input is coming from a terminal. For the tests (currently only deletion and move confirmations are covered), this means that the prompt itself cannot be covered, and an empty line instead has to be expected. (On the positive side, this removes the ugly trick with $SPACE.)
* 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.
