Stowage

Needed information for generation:

• short option
• long option
• short description (for usage ouput)
• long description (for manpage output)

Machine specific configuration

• Selection based on file name
• Config section selection based on pattern with machine name
• Possibly variable insertion and comment removal

Option Parsing

Parsed from left to right.

Types

• Short option
• Long option
• Argument to option
• Non-option parameter (default argument)

Short Option

'-' followed by short option character. If option has required argument, directly after OR separated by white-space. Optional argument must be directly after the option character.

Possible to write several short options after one '-', if all (except last) do not have required or optional arguments.

Long Option

'–' followed by long option name. If option has a required argument, directly after, separated by '' OR white-space. Optional argument must be directly after the option, separated by ''.

Non-option Parameter

Each parameter not starting with '-' and not a required argument of a previous option, is a non-option parameter.

Each parameter after a '–' parameter is always interpreted as a non-option parameter.

Examples

./stowage -Fals
./stowage -F -a -l -s

./stowage --file --add --pull --push

./stowage -r filename
./stowage -rfilename
./stowage --remove=filename
./stowage --remove filename

./stowage --remove filename other stuff
./stowage --remove filename -- other stuff

Multiple of the same options

./stowage -e pattern1 -epattern2 --regexp=pattern3 --regexp pattern4

TODO [24/38]

• macros: add more EXPECT_
• macros: print to stderr, add colors
• suite: improve printing style
• convert more tests from main()
• suite: add time tracking
• suite: print time info
• suite: add mechanism for EXPECT_ macros to mark current test as failed
• suite: print suite failed tests
• argparser: after first non option, go into no-option mode. this should be a setting to enable (default off)
• argparser: support '–' to go into non-option mode
• argparser: add multi-option support, vectors!
• argparser: support non-option arguments parsing + storing
• argparser: non-option arguments, what error messages, when?
• argparser: update tests to check non-option arguments
• argparser: add addOption overloads
• argparser: generate usage string
• argparser: generate man page string
• argparser: parse() function to return bool false if any error has occurred
• argparser: setting for failure behavior (usage/exit/usage+exit)
• argparser: add proper tests for non-existent options
• argparser: m_exitOnFirstError is implemented wrong in longOption, should also break in the main loop! I think its fine in shortOption as it can parse multiple arguments
• argparser: support optional arguments, if acceptvalue fails and arg is optional, increment index and try again
• argparser: receives empty parameters (at least arguments), decide what to do with them. $ uname bla => uname: extra operand ‘bla’
• argparser: dont use std::regex, just loop through characters and bail if unexpected
• argparser: support long option abbreviations, if they are not ambiguous
• argparser: support for single - long options
• argparser: check and set $value to $next before the if spaghetti to simplify, at least in longOption
• system: add piping functionality, print result of previous command to stdin before execvp() ?
• system: output/error/status getter, automatically call exec if workload
• system: output/error getter, cut off last character if its "\n", as std::string already handles trailing \n
• system: test with file descriptors captured in std::system
• system: write test cases
• system: fix bug: splitting on space needs to be escapable, ex: '\ ' or ' ' or " ", needs a lexer
• system: test if exec() can return a reference?
• dotfile: add loop index to forEachDotfile
• dotfile: convert excludePaths and system directories matching to regex
• dotfile: add excludePaths (ignore file) config file functionality https://systemcrafters.net/managing-your-dotfiles/using-gnu-stow/ https://www.gnu.org/software/stow/manual/stow.html#Types-And-Syntax-Of-Ignore-Lists
• dotfile: add system directories config file functionality
