* Add new `functions` flag -V/--inherit-variableGravatar Kevin Ballard2014-10-02
| | | | | | | | | | --inherit-variable takes a variable name and snapshots its current value. When the function is executed, it will have a local variable with this value already defined. Printing the function source will include synthesized `set -l` lines for the values. This is primarily useful for functions that are created on the fly, such as in `psub`.
* set: Print an error when setting `umask` to a bad valueGravatar Kevin Ballard2014-08-21
| | | | | | | | | Repurpose the ENV_INVALID return value for env_set(), which wasn't currently used by anything. When a bad value is passed for the 'umask' key, return ENV_INVALID to signal this and print a good error message from the `set` builtin. This makes `set umask foo` properly produce an error.

* Change how we separate toplevel and global scopesGravatar Kevin Ballard2014-07-13
| | | | | | | | | | | | Instead of introducing a new local scope at the point of `set`, merely push a new local scope at the end of env_init(). This means we have a single toplevel local scope across the lifetime of the fish process, which means that set -l foo bar echo $foo behaves as expected, without modifying the global environment.
* Add an optional mode to env_get_string()Gravatar Kevin Ballard2014-07-12
| | | | | | | | The mode restricts the scope in which the variable is searched for. Use this new restricted scope functionality in the `set` builtin. This fixes `set -g` to not show local shadowing variable values, and also allows for scoped erasing of slices.
* set: Print an error when setting a special var in the wrong scopeGravatar Kevin Ballard2014-07-12
| | | | | | | | | When attempting to set a readonly or electric variable in the local or universal scopes, print an appropriate error. Similarly, print an error when setting an electric variable as exported. In most cases this is simply a nicer error instead of the 'read-only' one, but for the 'umask' variable it prevents `set -l umask 0023` from silently changing the global value.
* set: Don't treat toplevel scope the same as globalGravatar Kevin Ballard2014-07-12
| | | | | | | | | | | When using the `set` command with the -l flag, if we're at the top level, create a temporary local scope. This makes query/assignment behavior be consistent with the value-printing behavior. This works by marking the current block as needing to pop the environment if a local scope was pushed. I assume this is safe to do. I also assume the current block is the right one to modify, rather than trying to walk up the stack to the root.

| | | | | | modify PATH in share/config.fish. Introduced variable fish_user_paths, and a glue function __fish_reconstruct_path that splices together PATH with fish_user_paths. Changed fish to no longer validate changes to PATH unless the paths are new (i.e. don't recheck what's already there). Modified certain sets to store const wchar_t instead of wcstring to save a few allocations. https://github.com/fish-shell/fish-shell/issues/527
