Configuring TexLab LSP with Kate

[JPenuchot]

Hi,

I've been trying to configure TexLab to build my documents and do a forward search with Zathura on every save. Sadly I can't get any of this to work: build doesn't happen, and neither does forward search.

I've been trying to look at the debug logs, the configuration is being passed properly and the didSave events are triggered.

Here's my Kate LSP Plugin configuration file at the moment:

{
    "servers": {
        "latex": {
            "command": [
                "texlab",
                "-vvv",
                "--log-file",
                "/tmp/texlog.txt"
            ],
            "settings": {
                "texlab": {
                    "build": {
                        "executable": "latexmk",
                        "args": [
                            "-pdf",
                            "-interaction=nonstopmode",
                            "-synctex=1",
                            "%f"
                        ],
                        "onSave": true,
                        "forwardSearchAfter": true
                    },
                    "forwardSearch": {
                        "executable": "zathura",
                        "args": [
                            "--synctex-forward=%l:1:%f",
                            "%p"
                        ]
                    },
                    "chktex": {
                        "onOpenAndSave": false,
                        "onEdit": false
                    },
                    "diagnosticsDelay": 300,
                    "formatterLineLength": 80,
                    "bibtexFormatter": "texlab",
                    "latexFormatter": "latexindent",
                    "latexindent": {
                        "local": null,
                        "modifyLineBreaks": true
                    }
                }
            }
        }
    }
}

And here's the workspace/didChangeConfiguration debug entry I'm getting:

DEBUG - < {
    "jsonrpc": "2.0",
    "method": "workspace/didChangeConfiguration",
    "params": {
        "settings": {
            "texlab": {
                "bibtexFormatter": "texlab",
                "build": {
                    "args": [
                        "-pdf",
                        "-interaction=nonstopmode",
                        "-synctex=1",
                        "%f"
                    ],
                    "executable": "latexmk",
                    "forwardSearchAfter": true,
                    "onSave": true
                },
                "chktex": {
                    "onEdit": false,
                    "onOpenAndSave": false
                },
                "diagnosticsDelay": 300,
                "formatterLineLength": 80,
                "forwardSearch": {
                    "args": [
                        "--synctex-forward=%l:1:%f",
                        "%p"
                    ],
                    "executable": "zathura"
                },
                "latexFormatter": "latexindent",
                "latexindent": {
                    "local": null,
                    "modifyLineBreaks": true
                }
            }
        }
    }
}

I tried a lot of things from using initializationOptions instead of settings to pass the parameters at the initialization stage, serializing field names instead of using the JSON hierarchy to pass parameters, also tried to use notify-send to verify that the Zathura invocation wasn't invalid notify-send wasn't even called. Getting TexLab to work would help me a lot, so any help would be very much appreciated.

@JPenuchot You need to omit the "texlab: {" from your configuration. It should be

{
    "servers": {
        "latex": {
            "command": [
                "texlab",
                "-vvv",
                "--log-file",
                "/tmp/texlog.txt"
            ],
            "settings": {
                "build": {
                    "executable": "latexmk",
                    "args": [
                        "-pdf",
                        "-interaction=nonstopmode",
                        "-synctex=1",
                        "%f"
                    ],
                    "onSave": true,
                    "forwardSearchAfter": true
                },
                "forwardSearch": {
                    "executable": "zathura",
                    "args": [
                        "--synctex-forward=%l:1:%f",
                        "%p"
                    ]
                },
                "chktex": {
                    "onOpenAndSave": false,
                    "onEdit": false
                },
                "diagnosticsDelay": 300,
                "formatterLineLength": 80,
                "bibtexFormatter": "texlab",
                "latexFormatter": "latexindent",
                "latexindent": {
                    "local": null,
                    "modifyLineBreaks": true
                }
            }
        }
    }
}

This works indeed, thank you so much!
