# 1. Guidelines
|
|
|
|
Have fun, and work on whatever floats your boat. Take It Easy :tm:.
|
|
|
|
Don't forget to **write documentation** for whatever it is you are doing.
|
|
See the ["Writing Documentation"](#writing-documentation) section.
|
|
|
|
Remember to write Vader tests for most of the code you write. You can look at
|
|
existing Vader tests in the `test` directory for examples.
|
|
|
|
When writing code, follow the [Google Vimscript Style
|
|
Guide](https://google.github.io/styleguide/vimscriptguide.xml), and run `vint
|
|
-s` on your files to check for most of what the guide mentions and more. If you
|
|
install this plugin (ALE) and install [Vint](https://github.com/Kuniwak/vint), it
|
|
will check your code while you type.

# 2. Creating Issues
|
|
|
|
Before creating any issues, please look through the current list of issues and
|
|
pull requests, and ensure that the issue hasn't already been reported. If an
|
|
issue has already been reported, but you have some new insight, please add
|
|
a comment to the existing issue.
|
|
|
|
Please read the FAQ in the README before creating any issues. A feature
|
|
you desire may already exist and be documented, or the FAQ might explain
|
|
how to solve a problem you have already.
|
|
|
|
Please try and describe any issues reported with as much detail as you can
|
|
provide about your Vim version, the linter you were trying to run, your
|
|
operating system, or any other information you think might be helpful.
|
|
|
|
Please describe your issue in clear, grammatically correct, and easy to
|
|
understand English. You are more likely to see an issue resolved if others
|
|
can understand you.

# 3. Creating Pull Requests
|
|
|
|
For code you write, make sure to credit yourself at the top of files you add,
|
|
and probably those you modify. You can write some comments at the top of your
|
|
VIM files.
|
|
|
|
```vim
|
|
" Author: John Smith <john.smith@gmail.com>
|
|
" Description: This file adds support for awesomelinter for the best language ever.
|
|
```
|
|
|
|
If you want to credit multiple authors, you can comma separate them.
|
|
|
|
```vim
|
|
" Author: John Smith <john.smith@gmail.com>, Jane Doe <https://jane-doe.info>
|
|
```

# 3.i. Adding a New Linter
|
|
|
|
If you add a new linter, look for existing handlers first in the
|
|
[handlers.vim](autoload/ale/handlers.vim) file. One of the handlers there may
|
|
already be able to handle your lines of output. If you find that your new
|
|
linter replicates an existing error handler, consider pulling it up into the
|
|
[handlers.vim](autoload/ale/handlers.vim) file, and use the generic handler in
|
|
both places.
|
|
|
|
When you add a linter, make sure the language for the linter and the linter
|
|
itself are present in the table in the [README.md](README.md) file and in the
|
|
Vim [help file](doc/ale.txt). The programs and linters should be sorted
|
|
alphabetically in the table and list.
|
|
|
|
<a name="adding-new-options"></a>
|
|
|
|
# 3.ii. Adding New Options
|
|
|
|
If you add new options to the plugin, make sure to document those new options
|
|
in the [README.md](README.md) file, and also in the [help file](doc/ale.txt).
|
|
Follow the format of other options in each. Global options should appear in the
|
|
README file, and in the relevant section in the help file. Options specific
|
|
to a particular linter should appear in the section for that linter.
|
|
|
|
Linter options for customizing general argument lists should be named
|
|
`g:ale_<filetype>_<linter>_options`, so that all linters can have similar
|
|
global variable names.
|
|
|
|
Any options for linters should be set to some default value so it is always
|
|
easy to see what the default is with `:echo g:ale...`.
|
|
|
|

|
|
|
|
# 4. Writing Documentation
|
|
|
|
If you are adding new linters, changing the API, adding new options, etc., you
|
|
_must_ write some documentation describing it in the `doc/ale.txt` file. New
|
|
linters _must_ be added to the `README.md` file too, so other users can get a
|
|
quick overview of the supported tools.
|
|
|
|
<a name="documenting-new-linters"></a>
|
|
|
|
# 4.i Documenting New Linters
|
|
|
|
If you add a new linter to the project, edit the table in the `README.md` file,
|
|
and edit the list of linters at the top of the `doc/ale.txt` file. The linters
|
|
should be sorted vertically in lexicographic (alphabetical) order by the
|
|
programming language name or filetype, and the tools for each language should
|
|
be sorted in lexicographic order horizontally. Sorting in this manner is a fair
|
|
manner of presenting all of the information in an easy to scan way, without
|
|
giving some unfair preference to any particular tool or language.
|
|

|
|
|
|
# 4.ii Editing the Online Documentation
|
|
|
|
The "online documentation" file used for this project lives in `doc/ale.txt`.
|
|
This is the file used for generating `:help` text inside Vim itself. There are
|
|
some guidlines to follow for this file.
|
|
|
|
1. Keep all text within a column size of 79 characters, inclusive.
|
|
2. Open a section with 79 `=` or `-` characters, for headings and subheadings.
|
|
3. Sections should have a _single_ blank line before or after.
|
|
4. Between descriptions of variables/functions/commands, use _two_ blank lines.
|
|
5. Up-indent the description of a variable/function/command by two spaces.
|
|
6. Place tags at the ends of lines, with the final characters on column 79.
|
|
All of the tags should line up perfectly on the same column as you scan
|
|
down through the document.
|
|
7. Keep the table of contents balanced so the longest tag link ends on column
|
|
79, and so all links line up perfectly on their first character, on the
|
|
left.

|
|
|
|
# 4.iii Documenting Linter Options
|
|
|
|
For documenting new linter options, please add a new sub-section under the
|
|
"Linter Specific Options" section describing all of the global options added
|
|
for each linter, and what the default values of the options are. All global
|
|
options for linters should be set to some default value. This will allow users
|
|
to look up the default value easily by typing `:echo g:ale_...`.
|
|
|
|

# 5. In Case of Busses
|
|
|
|
Should the principal author of the ALE project and all collaborators with the
|
|
required access needed to properly administrate the project on GitHub or any
|
|
other website either perish or disappear, whether by tragic traffic accident
|
|
or government adduction, etc., action should be taken to ensure that the
|
|
project continues. If no one is left to administer the project where it is
|
|
hosted, please fork the project and nominate someone capable to administer it.
|
|
Preferably, in such an event, a single fork of the project will replace the
|
|
original, and life will go on, except the life of whoever vanished, because
|
|
then they will probably be dead.
|
|
|
|
Should w0rp suddenly disappear, then he was probably killed in a traffic
|
|
accident, or the government finally decided to kill him and make it look like
|
|
suicide. In the latter event, please subvert said government and restore
|
|
order to the universe, and ensure peace for mankind.
