* geesh/lexer.scm (get-quoted-here-doc): New function.
(get-unquoted-here-doc): New function.
(wrap-port-with-tab-trimming): New function.
(get-here-doc): New public function.
* tests/lexer.scm: Test it.
If a dollar sign does not precede a name, it gets treated normally.
* geesh/lexer.scm (get-parameter): Return '#f' if the first character
is not a name character.
(get-parameter-expansion): Propagate the '#f' value.
(get-word): Replace the '#f' value with last character read.
(get-parameter-word): Ditto.
(get-double-quotation): Ditto.
* tests/lexer.scm: Test this.
The right-hand side of a dup redirect ("<&" and ">&") may contain
expansions, so we cannot process it during parsing.
* geesh/parser.scm (process-dup-or-close-word): Remove function.
(make-parser): Return the raw word from a dup redirect instead of
trying to convert it into a number or a symbol.
* tests/parser.scm: Fix tests accordingly.
A reserved word should not be special when it is an argument to a
command. This commit makes the parser treat reserved words as normal
arguments. Note that this change exposed problems in many of the
parser tests, which relied on reserved words delimiting commands where
they should not. Those are now fixed.
* geesh/parser.scm (make-parser): Add reserved words to the default
'WORD*' rule, and use a new rule without reserved words for command
names.
* tests/parser.scm: Add a test for reserved words as arguments, and
fix old tests that relied on the old, incorrect behaviour.
* geesh/parser.scm (make-parser): Instead of using a nested list for
assignments, use a flat list.
* tests/parser.scm: Adjust existing test for this (which checks a
single assignment) and add a second test which checks multiple
assignments.
* gash/guix-build-utils.scm (<grep-match>): New record type.
(grep): New function.
* gash/builtins.scm (grep-command): New command.
(%builtin-commands): Add it.
* gash/guix-build-utils.scm (directory-exists?, executable-file?,
symbolic-link?): Import from Guix.
* gash/builtins.scm (test-command): Use them to enhance with file test.
* gash/builtins.scm (find-command-implementation): New function.
(find-command): New command.
(%builtin-commands): Add it.
* gash/guix-build-utils.scm (file-name-predicate, find-files): Import
from Guix.
* gash/environment.scm: New file.
* build-aux/build-guile.sh (SCM_FILES): Add it.
* gash/peg.scm: Include it.
(assignment, %global-variables, set-shell-opt!, variable): Remove.
* gash/config.scm.in:
* configure: Use it to generate gash/config.scm
* .gitignore: Ignore generated file.
* gash/gash.scm (display-version): Use it.
* build-aux/build-guile.sh: Compile it.
