pp (PAR-Packer) - how to access included data files

ibm1620 has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to use pp to build an executable that contains a data file from which it reads.

Here's the command I'm using:

pp -v=3 -a /Users/chap/private/dict/lex.dict -o ppdir/brillig brillig

Verbose output includes the line:

adding /Users/chap/private/dict/lex.dict as Users/chap/private/dict/lex.dict

The pp documentation of the -a switch is as follows:

-a, --addfile=FILE|DIR Add an extra file into the package. If the file is a directory, recursively add all files inside that directory, with links turned into actual files.
By default, files are placed under / inside the package with their original names. You may override this by appending the target filename after a ; like this: % pp -a "old_filename.txt;new_filename.txt"

I don't understand the bolded sentence. What path should my Perl code use to access lex.dict?

Thanks!

The post linked to by marto has a good example of checking if running under PAR and then accessing the file accordingly. More details about the environment variables used by PAR can be seen at https://metacpan.org/dist/PAR/view/lib/PAR/Environment.pod.	[reply]

I wasn't really clear about the use of PAR_TEMP, given the advice not to use it in https://metacpan.org/dist/PAR/view/lib/PAR/Environment.pod . I finally figured out that "/", which the doc says is the root under which included files are stored, could be computed at runtime by `dirname($ENV{PAR_0}) . "/inc"`.	[reply] [d/l]

`dirname($ENV{PAR_0}) . "/inc".` Why you want to go low level when you have this? : `# PAR::read_file() returns a file inside any loaded PARs my $conf = PAR::read_file('data/MyConfig.yaml');` [download] (from SYNOPSIS)	[reply] [d/l] [select]

The docs could be a bit clearer but my reading is that PAR_TEMP should not be assigned to but is fine to read from. Your approach will still work, though.	[reply]

If you want to get the contents of the file simply do this in your pl program: `use PAR; my $fileData = PAR::read_file('lex.dict');` [download] I believe this is the only real guaranteed way to get the file data. All other ways would be assuming things about how par unpacks and/or uses temp files, and/or enviroment variables, which are subject to change.	[reply] [d/l]
