Fixes #153.

Change

batpipe selected one of two viewer lists with an inverted command -v eza check. This change replaces the two lists with one list:

BATPIPE_VIEWERS=("eza" "exa" "ls" "tar" "tar_gz" "tar_bz2" "unzip" "gunzip" "xz")

The change keeps the intent of the two earlier changes:

• change all references to exa to eza #105 wanted exa as a fallback when eza is not installed. Each viewer_*_supports function except viewer_ls_supports already checks its command. Thus the order "eza" "exa" gives this fallback, and ls stays the last directory viewer.
• batpipe: Add support for gzipped and bzipped tar files #103 added the tar_gz and tar_bz2 viewers to one list. The merge with change all references to exa to eza #105 (ba984f4) put them in different lists.

Tests

The second commit adds three tests to test/suite/batpipe.sh and two small archives to test/data:

• viewer_tar_gz and viewer_tar_bz2 open a file inside a .tgz and a .tbz archive. Each test runs once with the current PATH and once with an eza stub first on the PATH.
• viewer_eza makes sure that batpipe uses eza for directories when eza is installed.

Results of ./test.sh --suite batpipe:

Environment	Before the change	After the change
eza installed	5 of 8 pass (viewer_tar_gz and viewer_eza fail)	7 of 8 pass
No eza in PATH	4 of 8 pass (viewer_tar_bz2, viewer_tar_gz and viewer_eza fail)	7 of 8 pass

batpipe_term_width fails in all four runs. It also fails on master without this change, so it is not related to this change.

The CI failures are not caused by this change:

• Build: GitHub stops the job at setup because the workflow uses the deprecated actions/upload-artifact@v3.
• Test: only batpipe_term_width fails. The same test fails on master without this change.

The Build and Test jobs failed in the same way on master in run 27102970337. The three new tests (viewer_tar_gz, viewer_tar_bz2, viewer_eza) pass on CI.

#156 fixes the two CI failures of this pull request (#147, #155). All CI jobs of #156 pass. After #156 is merged, I will rebase this pull request so that its CI passes too.
