The elvdocs still use the old format (#elvdoc:fn or #elvdoc:var) for now, but
will be changed to "fn" and "var" forms soon.
Also remove the accidentally committed cmd/mvelvdoc. It has been used to perform
the conversion automatically but is not supposed to be committed.
The PureEvaler abstraction made things unnecessarily complex; it's better to
just create a real Evaler for tests is pretty.
The Evaler has a new ReplaceBuiltin method to make it easier to construct the
expected test result.
I was surprised to see so many legacy lambda syntax examples in the
documentation. This replaces all of them with the new syntax -- excluding
the handful of cases meant to explicitly verify the legacy form is still
valid. This also adds a link to the issue in the release notes which
documents the change in syntax.
Related #664
Some of the variables are added after the Evaler is created, but that change was
not synchronized back to the copy of the builtin module that is imported with
"use builtin".
This fixes#1414.
- Move from pkg/eval/mods to pkg/mods
- Introduce mods.AddTo that adds all standard library modules
- Move epm and readline-binding into their own packages
The `edit:after-command` hooks are called with a single argument:
a pseudo-map with these keys:
"command": the command line that was run
"duration": the execution duration in seconds
"error": any error that occurred ($nil if no error occurred)
The `edit:command-duration` variable is the elapsed seconds (as a
float64) of the most recently run interactive command.
Resolves#1029
This commit replaces scopeOp, the only remaining place that mutates *Ns in
place, with nsOp, which performs copy-on-write for *Ns.
As a result, the "eval" command no longer mutates the passed namespace. The
default namespace it uses is also changed to match the default of "-source" (an
amalgamated namespace from the local and upvalue scopes), making "-source $file"
equivalent to "eval (slurp <$file)", and formally deprecated.
Another result is that (*Evaler).Eval can now guard the mutation of the global
namespace with the mutex, making it concurrency-safe to execute multiple sources
that touch the global namespace.
This fixes#1137.
- Move NewEnvListVar to pkg/eval/vars.
- De-export GlobPattern, GlobFlag and ExternalCmd.
- Merge editor.go and chdir.go into eval.go, value_helper.go into compile_value.go.
- Remove eval_internal_test.go and replace it with a new test for $pid.
This change makes Ns immutable from the exposed API. Internally there is exactly
one place that still mutates Ns, in scopeOp; this will be addressed later.
