A core library to support language servers.
I write many language servers and they share some same code so I extract the
shared code to this library.
I've had enough of writing many DSLs in my editor without any LSP support
(completion, hover, ...). So I decide to sacrifice my time to do this work.
## Language servers
- [termux-language-server](https://github.com/termux/termux-language-server/):
for some specific bash scripts:
- [`build.sh`](https://github.com/termux/termux-packages/wiki/Creating-new-package)
- [`PKGBUILD`](https://wiki.archlinux.org/title/PKGBUILD)
- [`*.ebuild`](https://dev.gentoo.org/~zmedico/portage/doc/man/ebuild.5.html)
- ...
- [mutt-language-server](https://github.com/neomutt/mutt-language-server):
for [(neo)mutt](https://github.com/neomutt/neomutt)'s (neo)muttrc
- [More](https://github.com/Freed-Wu?tab=repositories&q=lsp-server)
## Usage
### Schema
A `Trie` to convert a file to a json, then you can use json schema to validate
it to get diagnostics.
Take
[termux-language-server](https://github.com/termux/termux-language-server/) as
an example.
`PKGBUILD`:
```sh
pkgname=hello
pkgver=0.0.1
pkgrel=1
pkgdesc="hello"
arch=(wrong_arch)
license=(GPL3)
build() {
cat <<EOF > hello
#!/usr/bin/env sh
echo hello
EOF
}
package() {
install -D hello -t $pkgdir/usr/bin
}
```
```sh
termux-language-server --convert PKGBUILD
```
```json
{
"pkgname": "hello",
"pkgver": "0.0.1",
"pkgrel": "1",
"pkgdesc": "hello",
"arch": [
"wrong_arch"
],
"license": [
"GPL3"
],
"build": 0,
"package": 0
}
```
So, we can validate the json by [a json schema](https://github.com/termux/termux-language-server/tree/main/src/termux_language_server/assets/json):
<!-- markdownlint-disable MD013 -->
```sh
$ termux-language-server --check PKGBUILD
PKGBUILD:5:7-5:17:error: 'wrong_arch' is not one of ['any', 'pentium4', 'i486', 'i686', 'x86_64', 'x86_64_v3', 'arm', 'armv6h', 'armv7h', 'armv8', 'aarch64']
```
<!-- markdownlint-enable MD013 -->
Sometimes it will be more complicated:
`neomuttrc`:
```neomuttrc
set allow_ansi=yes sleep_time = no ispell = aspell
set query_command = 'mutt_ldap_query.pl %s'
```
```sh
mutt-language-server --convert neomuttrc
```
```json
{
"set": {
"allow_ansi": "yes",
"sleep_time": "no",
"ispell": "aspell",
"query_command": "mutt_ldap_query.pl %s"
}
}
```
```sh
$ mutt-language-server --check neomuttrc
neomuttrc:1:33-1:35:error: 'no' is not of type 'number'
```
We put the result to the json's `.set` not `.` just in order to reserve the
other keys for other usages.
### Finders
Some finders to find the required node in tree-sitter's AST.
Such as, if you want to get the node under the cursor:
```python
@self.feature(TEXT_DOCUMENT_COMPLETION)
def completions(params: CompletionParams) -> CompletionList:
document = self.workspace.get_document(params.text_document.uri)
uni = PositionFinder(params.position, right_equal=True).find(
document.uri, self.trees[document.uri]
)
# ...
```
UNI (Universal Node Identifier) is URI + node.
### Utilities
This library also provides many utility functions. Such as converting man page to
markdown and tokenizing it in order to generate the json schema.
```sh
mutt-language-server --generate-schema neomuttrc
```
<!-- markdownlint-disable MD013 -->
````json
{
"$id": "https://github.com/neomutt/mutt-language-server/blob/main/src/termux_language_server/assets/json/neomuttrc.json",
"$schema": "http://json-schema.org/draft-07/schema#",
"$comment": "Don't edit this file directly! It is generated by `mutt-language-server --generate-schema=neomuttrc`.",
"type": "object",
"properties": {
"account-hook": {
"description": "```neomuttrc\naccount-hook regex command\n```\nThis hook is executed whenever you access a remote mailbox. Useful to adjust configuration settings to different IMAP or POP servers."
},
"$comment": "..."
}
}
````
<!-- markdownlint-enable MD013 -->
## Template
This project provides a template for
[copier](https://github.com/copier-org/copier).
For example, you want to create a language server for a filetype named
[`zathurarc`](https://pwmt.org/projects/zathura/documentation/). Please follow
the following steps:
### Create a tree-sitter parser
1. Create a tree-sitter-parser from [template](https://github.com/tree-sitter-grammars/template).
2. Publish it to PYPI
You can see if
[py-tree-sitter-languages](https://github.com/grantjenks/py-tree-sitter-languages)
supports the language where you want to create a language server.
### Copy a template
```sh
$ copier copy -rHEAD gh:neomutt/lsp-tree-sitter /path/to/your/XXX-language-server
🎤 What is your language name?
zathurarc
🎤 What is your file patterns? split by " "

```
1. Edit `schema.py` to convert a tree-sitter's tree to a json, which is the
core function of `XXX-langauge-server --convert`
2. Edit a `misc/XXX.py` to generate json schemas, which is the core function of
`XXX-languageserver --generate-schema`
3. Edit `server.py` to make sure the LSP features can work for specific
tree-sitter parsers.
4. Edit `queries/XXX.scm` to make sure the LSP features can work for specific
tree-sitter parsers if you use them.
5. Edit `finders.py` to add the language specific finders for
`XXX-languageserver --check` and `XXX-languageserver --format`
### Test if it can work
```sh
$ git init
$ pip install -e .
$ which zathura-language-server
~/.local/bin/zathura-language-server
```
1. Refer `docs/resources/configure.md` to configure your language server for
your editor.
2. Refer `README.md` to see the LSP features provided by your language server.
```sh
vi /path/to/zathurarc
```
You can test the LSP features.
Refer <https://docs.readthedocs.io> to see how to publish the documents.
## References
These following language servers can be a good example for beginners:
### [zathura-language-server](https://github.com/Freed-Wu/zathura-language-server)
`zathurarc`'s syntax only has 4 directives:
- `set option value`
- `include /the/path`
- `map key function`
- `unmap key`
Very few directives make creating
[tree-sitter-zathurarc](https://github.com/Freed-Wu/tree-sitter-zathurarc) and
editing `schema.py` very easy. So I am highly recommended starting from it.
### [tmux-language-server](https://github.com/Freed-Wu/tmux-language-server)
`tmux.conf` is more complex than `zathurarc`. It has not only
`set option = value` and `source /the/path`, but also 170+ other directives.
### [mutt-language-server](https://github.com/neomutt/mutt-language-server)
`muttrc` or `neomuttrc` has the following directives:
- `set option = value`
- `source /the/path`
- 80+ other directives
However, its `set` syntax is very flexible. The following syntaxes are legal:
- `set option2 = value1 option2 = value2 ...`
- `set option`: a shortcut for `set option = yes`
- `set nooption`: a shortcut for `set option = no`
- `set invoption`
- `set nooption1 invoption2 option3 ...`
- ...
So, in fact it is harder than `tmux.conf`, IMO.
### [termux-language-server](https://github.com/termux/termux-language-server)
`build.sh`, `PKGBUILD`, `*.ebuild` use same syntax of bash. However, they use
different json schemas. If the language where you want to create a language
server, you can refer it to know how to handle this situation.

Publish it to PYPI\n\nYou can see if\n[py-tree-sitter-languages](https://github.com/grantjenks/py-tree-sitter-languages)\nsupports the language where you want to create a language server.\n\n### Copy a template\n\n```sh\n$ copier copy -rHEAD gh:neomutt/lsp-tree-sitter /path/to/your/XXX-language-server\n\ud83c\udfa4 What is your language name?\nzathurarc\n\ud83c\udfa4 What is your file patterns? split by \" \"\n*.zathurarc zathurarc\n\ud83c\udfa4 What is your project name?\nzathura-language-server\n\ud83c\udfa4 What is your Python module name?\nzathura_language_server\n\ud83c\udfa4 What is your Python class name?\nZathuraLanguageServer\n\ud83c\udfa4 What is your tree-sitter parser name?\ntree-sitter-zathurarc\n\ud83c\udfa4 What is your user name?\nwzy\n\ud83c\udfa4 What is your email?\n32936898+Freed-Wu@users.noreply.github.com\n\nCopying from template version None\ncreate .\n...\n$ cd /path/to/your/XXX-language-server\n$ tree .\n\ue5ff .\n\u251c\u2500\u2500 \ue5ff docs # documents\n\u2502 \u251c\u2500\u2500 \ue5ff api\n\u2502 \u2502 \u2514\u2500\u2500 \uf48a zathura-language-server.md\n\u2502 \u251c\u2500\u2500 \ue606 conf.py\n\u2502 \u251c\u2500\u2500 \uf48a index.md\n\u2502 \u251c\u2500\u2500 \ue606 requirements.txt\n\u2502 \u2514\u2500\u2500 \ue5ff resources\n\u2502 \u251c\u2500\u2500 \uf48a configure.md\n\u2502 \u251c\u2500\u2500 \uf48a install.md\n\u2502 \u2514\u2500\u2500 \uf48a requirements.md\n\u251c\u2500\u2500 \uf02d LICENSE\n\u251c\u2500\u2500 \ue606 pyproject.toml\n\u251c\u2500\u2500 \uf48a README.md\n\u251c\u2500\u2500 \ue5ff requirements # optional dependencies\n\u2502 \u251c\u2500\u2500 \uf15c colorize.txt\n\u2502 \u251c\u2500\u2500 \uf15c dev.txt\n\u2502 \u2514\u2500\u2500 \uf15c misc.txt\n\u251c\u2500\u2500 \ue606 requirements.txt\n\u251c\u2500\u2500 \ue5ff src\n\u2502 \u2514\u2500\u2500 \ue5ff zathura_language_server\n\u2502 \u251c\u2500\u2500 \ue606 __init__.py\n\u2502 \u251c\u2500\u2500 \ue606 __main__.py\n\u2502 \u251c\u2500\u2500 \ue606 _shtab.py\n\u2502 \u251c\u2500\u2500 \ue5ff assets\n\u2502 \u2502 \u251c\u2500\u2500 \ue5ff json # json schemas generated by misc/XXX.py\n\u2502 \u2502 \u2502 \u2514\u2500\u2500 \ue60b zathurarc.json\n\u2502 \u2502 \u2514\u2500\u2500 \ue5ff queries # tree-sitter queries\n\u2502 \u2502 \u2514\u2500\u2500 \uf15b import.scm\n\u2502 \u251c\u2500\u2500 \ue606 finders.py # project specific finders\n\u2502 \u251c\u2500\u2500 \ue5ff misc\n\u2502 \u2502 \u251c\u2500\u2500 \ue606 __init__.py\n\u2502 \u2502 \u2514\u2500\u2500 \ue606 zathurarc.py\n\u2502 \u251c\u2500\u2500 \uf15b py.typed\n\u2502 \u251c\u2500\u2500 \ue606 schema.py # project specific schemas\n\u2502 \u251c\u2500\u2500 \ue606 server.py # main file for server\n\u2502 \u2514\u2500\u2500 \ue606 utils.py\n\u251c\u2500\u2500 \ue5ff templates\n\u2502 \u251c\u2500\u2500 \uf15c class.txt\n\u2502 \u251c\u2500\u2500 \uf15c def.txt\n\u2502 \u251c\u2500\u2500 \uf15b metainfo.py.j2\n\u2502 \u2514\u2500\u2500 \uf15c noarg.txt\n\u2514\u2500\u2500 \ue5ff tests\n\u2514\u2500\u2500 \ue606 test_utils.py\n```\n\n1. Edit `schema.py` to convert a tree-sitter's tree to a json, which is the\n core function of `XXX-langauge-server --convert`\n2. Edit a `misc/XXX.py` to generate json schemas, which is the core function of\n `XXX-languageserver --generate-schema`\n3. Edit `server.py` to make sure the LSP features can work for specific\n tree-sitter parsers.\n4. Edit `queries/XXX.scm` to make sure the LSP features can work for specific\n tree-sitter parsers if you use them.\n5. Edit `finders.py` to add the language specific finders for\n `XXX-languageserver --check` and `XXX-languageserver --format`\n\n### Test if it can work\n\n```sh\n$ git init\n$ pip install -e .\n$ which zathura-language-server\n~/.local/bin/zathura-language-server\n```\n\n1. Refer `docs/resources/configure.md` to configure your language server for\n your editor.\n2. Refer `README.md` to see the LSP features provided by your language server.\n\n```sh\nvi /path/to/zathurarc\n```\n\nYou can test the LSP features.\n\nRefer <https://docs.readthedocs.io> to see how to publish the documents.\n\n## References\n\nThese following language servers can be a good example for beginners:\n\n### [zathura-language-server](https://github.com/Freed-Wu/zathura-language-server)\n\n`zathurarc`'s syntax only has 4 directives:\n\n- `set option value`\n- `include /the/path`\n- `map key function`\n- `unmap key`\n\nVery few directives make creating\n[tree-sitter-zathurarc](https://github.com/Freed-Wu/tree-sitter-zathurarc) and\nediting `schema.py` very easy. So I am highly recommended starting from it.\n\n### [tmux-language-server](https://github.com/Freed-Wu/tmux-language-server)\n\n`tmux.conf` is more complex than `zathurarc`. It has not only\n`set option = value` and `source /the/path`, but also 170+ other directives.\n\n### [mutt-language-server](https://github.com/neomutt/mutt-language-server)\n\n`muttrc` or `neomuttrc` has the following directives:\n\n- `set option = value`\n- `source /the/path`\n- 80+ other directives\n\nHowever, its `set` syntax is very flexible. The following syntaxes are legal:\n\n- `set option2 = value1 option2 = value2 ...`\n- `set option`: a shortcut for `set option = yes`\n- `set nooption`: a shortcut for `set option = no`\n- `set invoption`\n- `set nooption1 invoption2 option3 ...`\n- ...\n\nSo, in fact it is harder than `tmux.conf`, IMO.\n\n### [termux-language-server](https://github.com/termux/termux-language-server)\n\n`build.sh`, `PKGBUILD`, `*.ebuild` use same syntax of bash. However, they use\ndifferent json schemas. If the language where you want to create a language\nserver, you can refer it to know how to handle this situation.\n\n### Other references\n\nSome useful URLs for beginners who want to develop language servers:\n\n- some [Chinese blogs](https://freed-wu.github.io/tag/lsp/) about how I write\n these language servers\n- [tree-sitter](https://tree-sitter.github.io/tree-sitter/)\n- [language server protocol](https://microsoft.github.io/language-server-protocol/specifications/specification-current)\n- [json schema](https://json-schema.org/specification)\n",
