This adjustment paves the way for writing a compiler.
* gash/word.scm (eval-cmd-sub, string-not-null?, word->qword,
expand-word): Move these...
* gash/eval.scm: ...to this module.
* tests/unit/word.scm: Adjust qword tests to use 'expand-qword', and
move non-qword (evaluation) tests to...
* tests/unit/eval.scm: ...this new file, adjusting them to use
'eval-word'.
* Makefile.am (UNIT_TESTS): Add the new file.
The old implementation had several bugs, prompting this complete
rewrite.
* gash/compat/srfi-43.scm (vector-empty?): New procedure.
* gash/pattern.scm (pattern-null?): New procedure.
* gash/word.scm (qword->pattern-string): New procedure.
(qword->pattern): Rewrite using 'qword->pattern-string'.
(find-files): New procedure.
(expand-pathnames): Rewrite using 'find-files' and add a docstring.
* tests/unit/word.scm: Add tests.
(mock): New syntax.
(make-pure-scandir): New procedure.
(with-mocked-files): New syntax.
These were mixed up, with ':+' behaving like '+' and vice versa.
* gash/word.scm (word->qword): Swap implementations of '<sh-ref-and>'
and '<sh-ref-and*>'.
* tests/unit/word.scm: Swap tests.
* gash/word.scm (word->qword): Add an implementation for the
'<sh-ref-assert>' and '<sh-ref-assert*>' cases.
* tests/variable-operators.org: New file.
* Makefile.am (FULL_TESTS): Add it.
This commit adds an implementation for the '#', '##', '%', and '%%'
variable operators.
* gash/word.scm (word->qword): Add an implementation for the
'<sh-ref-except-min>', '<sh-ref-except-max>', '<sh-ref-skip-min>',
and '<sh-ref-skip-max>' cases.
gash/environment.scm: Remove file.
geesh/*: Move these files into the 'gash' folder and replace all
instances of the word 'geesh'.
scripts/geesh.in: Remove file.
HACKING, INSTALL, Makefile.am, configure.ac, guix.scm,
tests/bootstrap/bash-without-bash.scm, tests/spec/Makefile.am,
tests/spec/check-spec, tests/spec/oil.scm, tests/unit/*,
tools/coverage.in: Replace all instances of the word 'geesh'.
