These allow for displaying additional inline information,
such as the types of variables, names operands/results,
constraint/rewrite arguments, etc. This requires a bump in the
vscode extension to a newer version, as inlay hints are a new LSP feature.

This commit adds a new PDLL specific LSP command, pdll.viewOutput, that
allows for viewing the intermediate outputs of a given PDLL file. The available
intermediate forms currently mirror those in mlir-pdll, namely: AST, MLIR, CPP.
This is extremely useful for a developer of PDLL, as it simplifies various testing,
and is also quite useful for users as they can easily view what is actually being
generated for their PDLL files.
This new command is added to the vscode client, and is available in the right
client context menu of PDLL files, or via the vscode command palette.

This provides a format for externally specifying the include directories
for a source file. The format of the tablegen database is exactly the
same as that for PDLL, namely it includes the absolute source file name and
the set of include directories. The database format is shared to simplify
the infra, and also because the format itself is general enough to share. Even
if we desire to expand in the future to contain the actual compilation command,
nothing there is specific enough that we would need two different formats.
As with PDLL, support for generating the database is added to our mlir_tablegen
cmake command.

This follows the same general structure of the MLIR and PDLL language
servers. This commits adds the basic functionality for setting up the server,
and initially only supports providing diagnostics. Followon commits will
build out more comprehensive behavior.
Realistically this should eventually live in llvm/, but building in MLIR is an easier
initial step given that:
* All of the necessary LSP functionality is already here
* It allows for proving out useful language features (e.g. compilation databases)
without affecting wider scale tablegen users
* MLIR has a vscode extension that can immediately take advantage of it

The compilation database acts in a similar way to the compilation database
(compile_commands.json) used by clang-tidy, i.e. it provides additional
information about the compilation of project files to help the language
server. The main piece of information provided by the PDLL compilation
database in this commit is the set of include directories used when processing
the input .pdll file. This allows for the server to properly process .pdll files
that use includes anchored by the include directories set up in the build system.
The structure of the textual form of a compilation database is a yaml file
containing documents of the following form:
```
--- !FileInfo:
filepath: <string> - Absolute file path of the file.
includes: <string> - Semi-colon delimited list of include directories.
```
This commit also adds support to cmake for automatically generating
a `pdll_compile_commands.yml` file at the top-level of the build
directory.

This avoids emitting errors in situations where the user doesn't have a server
setup, and doesn't mean to (e.g. when they merely want syntax highlighting).

We currently proactively create language clients for every workspace folder,
and every language. This makes startup time more costly, and also emits errors
for missing language servers in contexts that the user currently isn't in. For example,
if a user opens a .mlir file we don't want to emit errors about .pdll files. We also don't
want to emit errors for missing servers in workspace folders that don't even utilize
MLIR.
This commit refactors client creation to lazy-load when a document that requires the
server is opened.
Differential Revision: https://reviews.llvm.org/D123184
In a previous commit we added proper support for separate configurations
per workspace folder, but that effectively broke support for processing out-of-workspace
files. Given how useful this is (e.g. when iterating on a test case in /tmp), this
commit refactors server creation to support this again. We support this case using
a "fallback" server that specifically handles files not within the workspace. This uses
the configuration settings for the current workspace itself (not the specific folder).
Differential Revision: https://reviews.llvm.org/D123183
We currently only launch one set of language clients when starting the extension,
but this has the unfortunate effect of applying the same settings to all workspace
folders. This commit adds support for multiple workspace folders by launching
a server for each folder in the workspace. This allows for having different servers
for different workspace folders, e.g. when there are multiple MLIR projects in
the same workspace.
Differential Revision: https://reviews.llvm.org/D122793
We currently require that server paths are full paths, which is
fairly inconvenient for a myriad of reasons. This commit
attempts to resolve a given server path with the current workspace.
This has a nice additional affect that we can now actually have
default server paths. This means that mlir-lsp-server and
mlir-pdll-lsp-server can be transparently picked up from
build directories (i.e. generally no need for upstream users to
configure the extension).
Fixes#54627
Differential Revision: https://reviews.llvm.org/D122792
This commits adds a basic language server for PDLL to enable providing
language features in IDEs such as VSCode. This initial commit only
adds support for tracking definitions, references, and diagnostics, but
followup commits will build upon this to provide more significant behavior.
In addition to the server, this commit also updates mlir-vscode to support
the PDLL language and invoke the server.

This allows for reusing the same output channel when the extension reloads after updating the server. Currently, whenever the extension restarts a new output channel is created (which can lead to a large number of seemingly dead output channels).
This revision adds detection for changes to either the mlir-lsp-server binary or the setting, and prompts the user to restart the server. Whether the user gets prompted or not is a configurable setting in the extension, and this setting may updated based on the user response to the prompt.
Differential Revision: https://reviews.llvm.org/D104501
This utilizes the mlir-lsp server to provide language services for MLIR files opened in vscode. The extension currently supports syntax highlighting, as well as tracking definitions/uses/source locations for SSA values and blocks.
