Don't set error offset for $status This would break the location of any prior errors without doing anything of value. E.g. ```fish echo foo | exec grep # this exec is not allowed! $status somethingelse # The error might be found here! ``` Would apply the offset of `$status` to the offset of `exec`, locating the error for `exec` somewhere after $status!
2021-09-28 23:15:33 +08:00
#RUN: %fish -C 'set -g fish %fish' %s
# A $status used as a command should not impact the location of other errors.
echo 'echo foo | exec grep # this exec is not allowed!
$status
# The error might be found here!' | $fish 2>| string replace -r '(.*)' '<$1>'
# CHECK: <fish: The 'exec' command can not be used in a pipeline>
# CHECK: <echo foo | exec grep # this exec is not allowed!>

Don't add expansion error offset twice Like the $status commit, this would add the offset to already existing errors, so ```fish (foo) (bar) something ``` would see the "(foo)" error, store the correct error location, then see the "(bar)" error, and *add the offset of (bar)* to the "(foo)" error location. Solve this by making a new error list and appending it to the existing ones. There's a few other ways to solve this, including: - Stopping after the first error (we only display the first anyway, I think?) - Making it so the source location has an "absolute" flag that shows the offset has already been added (but do we ever need to add two offsets?) I went with the simpler fix.

Report sub-token error locations again This fixes a regression about where we report errors: echo error(here old: ^ fixed: ^ Commit 0c22f67bd (Remove the old parser bits, 2020-07-02) removed uses of "error_offset_within_token" so we always report errors at token start. Add it back, hopefully restoring the 3.1.2 behavior. Note that for cases like echo "$(" we report "unbalanced quotes" because we treat the $( as double quote. Giving a better error seems hard because of the ambguity - we don't know if quote is meant to be inside or outside the command substitution.

Autoload: Call the parser directly instead of going via "subshell" This used to call exec_subshell, which has two issues: 1. It creates a command substitution block which shows up in a stack trace 2. It does much more work than necessary This removes a useless "in command substitution" from an error message in an autoloaded file, and it speeds up autoloading a bit (not measurable in actual benchmarks, but microbenchmarks are 2x).

Make string syntax error location a bit more precise String tokens are subdivided by command substitutions. Some syntax errors can occur in the gap between two command substitutions. Make the caret point to the start of that gap, instead of the token start.

Revert "Remove print_hints from builtin_missing_argument and builtin_unknown_option" Unfortunately print_hints was true *by default* - so for all builtins that didn't pass it it would now be false instead. This resulted in the trailer missing, which includes the line number and context. So if you ran a script that includes `bind -M` the error message would now just be "bind: -M: option requires an argument", with no indication as to where. This reverts commit 8a50d47a469b547581c8fafede50d740230d42f2.

ast: Require `--help` to parse more keywords as decorated statement (#10000) This makes it so ```fish if -e foo # do something end ``` complains about `-e` not being a command instead of `end` being used outside of an if-block. That means both that `-e` could now be used as a command name (it already can outside of `if`!) *and* that we get a better error! The only way to get `if` to be a decorated statement now is to use `if -h` or `if --help` specifically (with a literal option). The same goes for switch, while and begin. It would be possible, alternatively, to disallow `if -e` and point towards using `test` instead, but the "unknown command" message should already point towards using `test` more than pointing at the "end" (that might be quite far away).

expand_cmdsubst: Make more errors known These printed "Unknown error while evaluating command substitution". Now they print something like ``` fish: for: status: cannot overwrite read-only variable for status in foo; end ^~~~~^ in command substitution fish: Invalid arguments echo (for status in foo; end) ^~~~~~~~~~~~~~~~~~~~~~~^ ``` for `echo (for status in foo; end)` This is, of course, still not *great*. Mostly the `fish: Invalid arguments` is basically entirely redundant. An alternative is to simply skip the error message, but that requires some more scaffolding (describe_with_prefix adds some error messages on its own, so we can't simply say "don't add the prefix if we don't have a message") (cherry picked from commit 1b5eec2af6e71998c2af31830be5236aeb15ffd6)
