`cpcalendars`
=============
*Really simple CLI app to copy Mac OS Calendar.app calendars sources to other location.*

Copy the calendar resources from the Mac OS Calendar app to the specified directory, building a pseudo-ICBU file. This file constitutes a comprehensive backup of your calendars.
In the first run it will need to be granted permissions for the Calendars app by System Integrity Protection system.
## Install
The recommended installation option is use Homebrew with the command:
```sh
brew install bglezseoane/tap/cpcalendars
```
You can only install the program with Cargo, with the command:
```sh
cargo install cpcalendars
```
## Use
The normal use of the tool is very simple. You only need to run:
```sh
cpcalendars
```
A folder named `All Calendars.icbu` will saved into ``.
### Achieve permissions against Mac OS System Integrity Protection
If your current **terminal app** has **Calendars.app access** or **full disk access** and you use `cpcalendars` **since it**, the tool will works fine. If you only want to work with `cpcalendars` **since your terminal** or since scripts used by you since your terminal, **the above is sufficient** and the following steps are irrelevant to your use case.
Otherwise, if you want to use the tool since an script routine as **`launchd` agent**, the tool is going to fail due to System Integrity Protection.
Mac OS System Integrity Protection block `cpcalendars` because the tool try to access the protected Calendars.app directories and it doesn't inherit permissions —**using it since the terminal, inherit terminal granted ones**—. To achieve permissions, you need to run the following command:
```sh
open -a '/usr/local/bin/cpcalendars' --args ""
```
When run the above command, **a pop up window appear** and you can grant access to your calendars to `cpcalendars`. **Do it** and the next time the tool will work.
The path `/usr/local/bin/cpcalendars` could be different if you have installed with Cargo. Any case, you can check it with `which cpcalendars`.
If your agent only needs to run the tool and no more stuff, you can add the following lines to the agent `Info.plist` and it will work (after previously indicated first execution):
```xml
ProgramArguments
/usr/local/bin/cpcalendars
destination
```
For any reason, to work with the tool since the `launchd` agent and **integrated in a shell script**, you need to always run it as `open -a '/usr/local/bin/cpcalendars' --args ""` and not directly as a command (e.g. `/usr/local/bin/cpcalendars `). I.e., if you use, e.g., the following agent specification...
```xml
ProgramArguments
/Users/You/scripts/script_which_calls_cpcalendars.sh
```
... you need to run `cpcalendars` as follows:
```sh
# 'script_which_calls_cpcalendars.sh'
# ...
open -a '/usr/local/bin/cpcalendars' --args ""
# And not '/usr/local/bin/cpcalendars
# ...
```
When run with `open -a`, the command don't return an error code if the launched application fails, so in order to integrate this step in a well designed script, the next approach is recommended:
```sh
# ...
# Create temporary file to save the output of the 'open' command
TMP_OPEN_CPCALENDARS_STDOUT=$(mktemp -t open_cpcalendars)
# Run and wait
open -W -a '/usr/local/bin/cpcalendars' \
--stdout "$TMP_OPEN_CPCALENDARS_STDOUT" \
--stderr "$TMP_OPEN_CPCALENDARS_STDOUT" \
--args
# Check and act attending to the process success
if grep -Fxq 'Error' "$TMP_OPEN_CPCALENDARS_STDOUT" \
|| ! grep -Fxq 'Process finished successfully.' "$TMP_OPEN_CPCALENDARS_STDOUT"
then
>&2 echo "Error using 'cpcalendars'."
rm "$TMP_OPEN_CPCALENDARS_STDOUT"
exit 1
fi
# Clean
rm "$TMP_OPEN_CPCALENDARS_STDOUT"
# ...
```
## Motivation
On my Mac OS machine I have some scripts that cannot work as agents because it is prevented by System Integrity Protection, which only allows granting permissions to binary programs. That, coupled with the fact that I wanted to learn the Rust language, motivated me to write this simple program in order to have the conflicting step in a compiled program to authorize it and can maintain my script routine working elegantly —and not pseudo-compiling shell scripts inserted them in a compiled language program—. However, at the end of the day `cpcalendars` is a potentially useful generic purpose program.
