The '#' character only introduces a comment if it occurs where a word
would begin. If it occurs within a word, it is not treated specially.
* geesh/lexer.scm (get-word): Do not treat '#' specially.
* geesh/lexer.scm (get-parameter-expansion): Include the current line
number with the variable name if it is 'LINENO'.
(call-with-metered-input-port): Set the line number of the soft port.
* geesh/word.scm (parameter-ref): Unpack the included line number when
the parameter name is 'LINENO'.
* test.sh: Increase test timeout from 1 to 10.
* Makefile.am (FULL_TESTS): Move tests/10-if-redirect.sh,
tests/50-redirect-space.sh, tests/50-redirect-sed.sh, and
tests/100-cd.sh from here...
(BROKEN_TESTS): ...to here.
* Makefile.am: Add Gash tests and use test.sh as the log compiler.
* test.sh: Use TEST_SHELL instead of SHELL to parameterize which shell
is being tested.
* tests/06-command-compound-word.sh: Adjust this test so that it works
even if the srcdir variable is set.
* .gitignore: Add tests/*.trs
This commit allows most of Gash to be built with Autotools. It also
removes some of the Gash build scripts.
* configure.ac: Add checks for compress, gzip, bzip2, and xz;
configure gash/config.scm.
* Makefile.am: Add Gash modules and the 'gash' script.
* scripts/gash.in: Rename 'guile_site_dir' to 'MODDIR' and
'guile_site_ccache_dir' to 'GODIR'.
* configure: Delete file.
* makefile: Delete file.
* build-aux/build-guile.sh: Delete file.
* build-aux/pre-inst-env.in: Delete file.
* build-aux/trace.sh: Delete file.
* .gitignore: Add configure; remove exceptions for the deleted
build-aux files.
When the system does not provide a compress executable, we use our
own. Before, this was done by installing an executable named
'compress' along with Gash. This commit allows the compressed-port
functions to use our built-in compress without needing an external
executable.
* gash/config.scm.in (exec-internal-compress): New function.
(%compress): Fall back to it on systems without compress.
* gash/guix-utils.scm (filtered-port, filtered-output-port): When the
given command list begins with a procedure, apply it to its arguments
instead of using execl.
This commit brings in the entire history of the Gash project. There
are a few conflicts, which are explained below.
* .dir-locals.el: Combine both files.
* .gitignore: Combine both files.
* COPYING: Use the Geesh version with HTTPS URLs.
* README: Use the Gash README.
* guix.scm: Use the Geesh package definition (the Gash one is
preserved in gash.guix.scm).
* build-aux/git-version-gen: New file.
* .gitignore: Do not ignore it.
* configure.ac: Use it to generate the version string.
* guix.scm: Ditto.
* Makefile.am: Make .tarball-version.
* configure.ac: Do not treat scripts/geesh as an AC_CONFIG_FILE.
* Makefile.am: Do the substitutions here (at make-time).
* scripts/geesh.in: Update %load-path and %load-compiled-path
explicitly before loading anything.
* geesh/environment.scm (*return-tag*): New variable.
(call-with-return): New public function.
(sh:return): New public function.
(*atexit*): New variable.
(*exiting?*) New variable.
(set-atexit!): New public function.
(sh:exit): New public function.
* geesh/repl.scm (run-repl): Call sh:exit at the end of a script.
* geesh/shell.scm (sh:exec-let): Use call-with-return for functions.
* geesh/built-ins/dot.scm (main): Use call-with-return.
These names are too common, and it will be even worse with 'exit'
and 'return'.
* geesh/environment.scm (break): Rename this...
(sh:break) ...to this.
(continue): Rename this...
(sh:continue) ...to this.
* geesh/built-ins/break.scm (main): Update call.
* geesh/built-ins/continue.scm (main): Ditto.
This commit fixes a problem with the old method of handling
here-documents. We used to ignore here-documents in many places where
they are valid (e.g., between Boolean operators). They are now valid
after any 'NEWLINE' token. To achieve this, the handling logic was
moved out of the parser and into the lexer. We now use a hook
mechanism to manage the necessary communication between the parser and
lexer.
* geesh/parser.scm (read-here-docs): Return strings instead of tokens.
(make-lexer): Add here-docs-hook as a keyword argument, and call it
after reading here-documents.
(make-parser): Let command-hooks transform commands, and remove
here-document handling rules.
(parse): Handle merging here-documents into commands.
* tests/parser.scm: Add tests for many less-intuitive here-document
locations.
* geesh/parser.scm (make-lexer): Remove the read-sh/bracketed and
read-sh/backquoted parameters.
(parse): New function.
(->command-list): New function.
(read-sh/bracketed, read-sh/backquoted, read-sh, read-sh-all):
Simplify by using the new functions.
