* Rakefile (.elc): Set byte-compile-force-lexical-warnings when
compiling.
(:compile_all): New target that compiles yasnippet-debug.el and
yasnippet-tests.el too.
* .travis.yml (script): Use it instead of `compile'. Update cl-lib to
0.6.1. Don't error on warnings for Emacs 24.3 on yasnippet-tests.el.
* yasnippet-debug.el: Don't use `yas--loaddir' if it's not
bound (e.g., when compiling). Require `color' and `edebug' at
toplevel. Check if `subr-x' defines `when-let'.
(yas-debug-snippet-vars): Remove, it was unused and broken.
* yasnippet-tests.el (yas-with-snippet-dirs, (yas-should-expand)
(yas--collect-menu-items, yas-should-not-expand, yas-mock-insert)
(yas-mock-yank, yas--key-binding, yas-make-file-or-dirs)
(yas-variables, yas-call-with-saving-variables)
(yas-call-with-snippet-dirs, special-mode, string-suffix-p): Move to
top section.
(yas-tests--ran-exit-hook): Rename from yas--ran-exit-hook, and move
to top-level.
* yasnippet.el (yas--letenv): Evaluate the FORMs of ENV.
* .travis.yml (install): Set warnings to (not cl-functions) if cl-lib
needs to be downloaded. Since the downloaded cl-lib just aliases cl.el
functions, trying to use cl- prefixed functions would cause compile
warnings otherwise.
* Rakefile: Pass environment variable `warnings' as
`byte-compile-warnings' value when compiling.
* .travis.yml: Don't use sudo, submodules.
(env): Test with additional Emacs versions.
(install): Get Emacs binaries from
https://github.com/npostavs/emacs-travis/releases. Download ert and
cl-lib if needed.
(script): Split compilation and testing into separate steps.
* Rakefile: Use batch-byte-compile. Treat compilation warnings as
errors.
* .travis.yml: new file
* README.mdown: Add Travis CI badge.
* Rakefile: use ert-run-tests-batch-and-exit.
* yasnippet-tests.el (example-for-issue-404-external-emacs): Use
`yas-with-snippet-dirs' to not depend on bundled snippets.
(yas--call-with-temporary-redefinitions): Use `cl-labels' since no
cl-flet in emacs-24.3's cl-lib.el.
(loading-with-cyclic-parenthood): prog-mode doesn't exist in emacs
24.3.
(yas-batch-run-tests): remove it.
* yasnippet.el (require): require cl-lib during byte-compilation
and load.
