2020-12-09common/file_util: Fix and deprecate CreateFullPath, add CreateDirsReinUsesLisp
Fix CreateFullPath to have its intended previous behavior (whatever that was), and deprecate it in favor of the new CreateDirs function. Unlike CreateDir, CreateDirs is marked as [[nodiscard]] to avoid new code ignoring its result value.
2020-12-09file_util: Migrate remaining file handling functions over to std::filesystemLioncash
Converts creation and deletion functions over to std::filesystem, simplifying our file-handling code. Notably with this, CopyDir will now function on Windows.
2020-12-08file_util: Migrate Exists() and IsDirectory() over to std::filesystemLioncash
Greatly simplifies our file-handling code for these functions.
2020-10-30General: Make ignoring a discarded return value an errorLioncash
Allows our CI to catch more potential bugs. This also removes the [[nodiscard]] attribute of IOFile's Open member function. There are cases where a file may want to be opened, but have the status of it checked at a later time.
2020-10-20Revert "core: Fix clang build"bunnei
2020-10-17core: Fix clang buildLioncash
Recent changes to the build system that made more warnings be flagged as errors caused building via clang to break. Fixes #4795
2020-08-16common/fileutil: Convert namespace to Common::FSLioncash
Migrates a remaining common file over to the Common namespace, making it consistent with the rest of common files. This also allows for high-traffic FS related code to alias the filesystem function namespace as namespace FS = Common::FS; for more concise typing.
2020-08-15common: Make use of [[nodiscard]] where applicableLioncash
Now that clang-format makes [[nodiscard]] attributes format sensibly, we can apply them to several functions within the common library to allow the compiler to complain about any misuses of the functions.
2020-07-20common: Add a screenshots directorylat9nq
Adds a screenshots directory as a path managed by FileUtil.
2020-04-15file_util: Early-exit in WriteArray and ReadArray if specified lengths are zeroLioncash
It's undefined behavior to pass a null pointer to std::fread and std::fwrite, even if the length passed in is zero, so we must perform the precondition checking ourselves. A common case where this can occur is when passing in the data of an empty std::vector and size, as an empty vector will typically have a null internal buffer. While we're at it, we can move the implementation out of line and add debug checks against passing in nullptr to std::fread and std::fwrite.
2019-05-23common/file_util: Make GetCurrentDir() return a std::optionalLioncash
nullptr was being returned in the error case, which, at a glance may seem perfectly OK... until you realize that std::string has the invariant that it may not be constructed from a null pointer. This means that if this error case was ever hit, then the application would most likely crash from a thrown exception in std::string's constructor. Instead, we can change the function to return an optional value, indicating if a failure occurred.
2019-05-23common/file_util: Make ReadFileToString and WriteStringToFile consistentLioncash
Makes the parameter ordering consistent, and also makes the filename parameter a std::string. A std::string would be constructed anyways with the previous code, as IOFile's only constructor with a filepath is one taking a std::string. We can also make WriteStringToFile's string parameter utilize a std::string_view for the string, making use of our previous changes to IOFile.
2019-05-23common/file_util: Remove unnecessary c_str() callsLioncash
The file stream open functions have supported std::string overloads since C++11, so we don't need to use c_str() here. Same behavior, less code.
2019-05-23common/file_util: Make IOFile's WriteString take a std::string_viewLioncash
We don't need to force the usage of a std::string here, and can instead use a std::string_view, which allows writing out other forms of strings (e.g. C-style strings) without any unnecessary heap allocations.
2019-02-06file_util: Add shader directoryReinUsesLisp
2018-10-02string_util: remove TString conversion for windowsWeiyi Wang
First of all they are foundamentally broken. As our convention is that std::string is always UTF-8, these functions assume that the multi-byte character version of TString (std::string) from windows is also in UTF-8, which is almost always wrong. We are not going to build multi-byte character build, and even if we do, this dirty work should be handled by frontend framework early.

2018-07-22file_util, vfs: Use std::string_view where applicableLioncash
Avoids unnecessary construction of std::string instances where applicable.
2018-07-21file_util: Use a u64 to represent number of entriesLioncash
This avoids a truncating cast on size. I doubt we'd ever traverse a directory this large, however we also shouldn't truncate sizes away.
2018-07-21file_util: Use an enum class for GetUserPath()Lioncash
Instead of using an unsigned int as a parameter and expecting a user to always pass in the correct values, we can just convert the enum into an enum class and use that type as the parameter type instead, which makes the interface more type safe. We also get rid of the bookkeeping "NUM_" element in the enum by just using an unordered map. This function is generally low-frequency in terms of calls (and I'd hope so, considering otherwise would mean we're slamming the disk with IO all the time) so I'd consider this acceptable in this case.
2018-07-19file_util: return string by const reference for GetExeDirectory()Lioncash
This disallows modifying the internal string buffer (which shouldn't be modified anyhow).

2018-07-02Add configurable logging backendsJames Rowe
2018-04-29file_util: Make move constructor/assignment operator and related functions ↵Lioncash
noexcept Without this, it's possible to get compilation failures in the (rare) scenario where a container is used to store a bunch of live IOFile instances, as they may be using std::move_if_noexcept under the hood. Given these definitely don't throw exceptions this is also not incorrect to add either.
2018-04-29file_util: Add static assertions to ReadBytes() and WriteBytes()Lioncash
Ensure that the actual types being passed in are trivially copyable. The internal call to ReadArray() and WriteArray() will always succeed, since they're passed a pointer to char* which is always trivially copyable.
2018-04-28file_util: Remove compiler version checks around is_trivially_copyable()Lioncash
The minimum clang/GCC versions we support already support this. We can also remove is_standard_layout(), as fread and fwrite only require the type to be trivially copyable.
