- Extracted `Colorize` class out of `Util` class. (The latter now only
contains static methods.)
- Renamed methods in `Colorize` class for improved clarity.
- Refactored as necessary to accommodate the changes above.
Performed a general refactoring, focusing on the following:
- Removing layers of abstraction in config handling
- Stubbing out proper config validator
- Updating envvar names located throughout the project
Added a missing `termcolor` dependency to `install_requires` in
`setup.py`. `termcolors` was introduced as an optional dependency when
the `CHEAT_HIGHLIGHT` envvar was implemented.
PR #391 changed the locaton into which system-wide cheatsheets are
installed to `/usr/share/cheat`, in order to comply with FHS. However,
this is causing conflicts with the `snap` packaging process.
This commit removes hard-coded references to `/usr/share/cheat` (outside
of `config/cheat`), and instead reads the cheat path via the
`CHEAT_PATH` config value (which may be set either in `cheat/config`, or
exported as an environment variable).
Lastly, this commit makes `setup.py` "aware of" the `CHEAT_PATH` env
var, allowing us to specify to where sytem-wide cheatsheets should be
installed during the `snap` build.
Previous pull-requests #406 and #413 attempted to resolve#372. They
were, however, never merged in.
Given that #391 was just merged (which rewrites a significant amount of
prior code), I here took what we learned from #406 and #413 and
re-implemented it. This approach will be less error-prone than
attempting to rebase either of the former on the changes introduced in
#391.
Constructors of classes which need direct access to configuration
now take Config class instance as parameter which will give them
better maintainability in the future
CHEAT_HIGHLIGHT has been added to Configuration class
Implemnted an assertion that `CHEAT_HIGHLIGHT` (if set) contains a value
that is acceptible to `termcolors`. This happens only once, upon the
invokation of `__main__`. If the assertion fails, `cheat` terminates
with an exit code of `1`.
PR #353 implemented highlighting on search terms within search results.
This PR:
- Merges the above
- Makes a few modifications upon the implementation
Specifically, the new implementation no longer relies on hard-coded
escape-sequences. Instead, a new `highlight` function has been created,
which in turn attempts to defer to the `termcolors` library to colorize
the necessary text.
