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.
This is a Bash-specific feature, which means that it is out of scope
for now.
* tests/variable-patterns.org (slash, slash-string,
slash-string-slash): Delete tests.
* gash/pattern.scm (string-contains-part-right): New procedure.
(pattern-drop): New procedure.
(pattern-drop-right): New procedure.
* tests/unit/pattern.scm: Test the dropping procedures.
* gash/compat/srfi-43.scm: New file.
* Makefile.am: Add it.
* gash/pattern.scm (<pattern>): New record type.
(parse-part): New procedure.
(parse-pattern): Return a '<pattern>'.
(pattern-plain?, pattern-match?): Accept a '<pattern>'.
(string-starts-with-part, string-ends-with-part,
string-contains-part): Treat 'part' as a vector.
The '(ice-9 textual-ports)' module is not needed, and using it breaks
the test suite on Guile 2.0.
* tests/run-test-suite.in: Do not use '(ice-9 textual-ports)'.
Thanks to Ludovic Courtès <ludo@gnu.org> for patching this in the Guix
package definition.
* build-aux/guile.am (moddir, ccachedir): Use the 'site' directories.
It turns out that 'with-continuation-barrier' allows delimited
continuations (i.e., prompts) to get through.
* gash/shell.scm (%subshell): Replace 'with-continuation-barrier' with
'dynamic-wind', making sure to preserve exit statuses that were leaked
through before.
* tests/unit/shell.scm (call-with-temporary-directory): Replace
'with-continuation-barrier' with 'dynamic-wind'.
* tests/spec/oil.scm: Enable previously failing tests.
* gash/built-ins/utils.scm (string->exit-status): New procedure.
* gash/built-ins/return.scm (main): Use it to simplify argument
checking; check for too many arguments; and print messages on
errors.
* tests/functions.org (Too many arguments to return): New test.
* gash/built-ins/utils.scm (string->positive-integer): New function.
* gash/built-ins/break.scm (main): Use it to simplify argument
checking; check for too many arguments; and print messages on errors.
* gash/built-ins/continue.scm (main): Ditto.
* gash/shell.scm (sh:exec-let): Throw an error if a special built-in
fails.
* tests/spec/oil.scm: Enable and adjust previously failing tests.
* build-aux/gitlab-ci.yml (before-script): Use a variable for the
Guile package version.
(test): Rename this...
(test-guile-2.2): ...to this and set the Guile version variable.
(test-guile-2.0): New job.
* doc/gash.texi: Add an introduction, add a discussion of included and
missing features, document the parser interface, and remove the
indexes.
* doc/syntax.txt: Update to match the manual.
This commit fixes many differences between the parser output and the
syntax document.
* gash/parser.scm (make-parser): Only wrap a command list with
'<sh-begin>' when necessary.
* tests/unit/parser.scm: Update tests accordingly.
* build-aux/guile-rules.am: Delete file.
* build-aux/guile.am: New file.
* .gitignore: Do not ignore it.
* Makefile.am: Adapt variable names to the new file.
* Makefile.am (scripts/gash): Make sure the 'scripts' directory exists
in the build tree.
(SH_LOG_COMPILER): Call 'test.sh' from the source tree.
* test.sh: Change the default test shell from 'scripts/gash' to
'gash'; export a 'TEST_TMP' variable that tells tests where to store
temporary files; and make sure all output is written to the build
directory.
tests/50-redirect-append.sh: Use the 'TEST_TMP' variable.
tests/60-subst.sh: Ditto.
Instead of building regular Bash using regular Gash, we now build
minimal Bash using the bootstrap build inputs, with bootstrap Bash
replaced by bootstrap Gash.
* tests/bootstrap/bash-without-bash.scm (gash-with-links): Rename this...
(%bootstrap-gash): ...to this, and use nothing but the bootstrap Guile
to build and run it.
(%bootstrap-coreutils&co-without-bash): New variable.
(%bootstrap-coreutils&co?): New function.
(%boot0-inputs): New variable.
This prevents Guile from complaining when compiling the project from
within the Guix build environment.
* build-aux/guile-rules.am: Set 'GUILE_AUTO_COMPILE' to '0' when
compiling.
