+
+  NOTE: mcs compiles sources in multiple phases. It stops compilation after

+  'FileWithSyntaxError.cs' exists which contains a syntax error 
+  (eg.: a missing '{'). 
+  In that case mcs and thus mcsc linter will stop after the syntax check phase is
+  finished and report the syntax error in the file 'FileWithSyntaxError.cs'. The
+  Type error in the file 'FileWithTypeError.cs is not seen jet.
+  The only possibility to find the error in in 'FileWithTypeError.cs' is to fix
+  the syntax error in 'FileWithSyntaxError.cs' first. After saving mcs will

-3. Global Options                                                 *ale-options*
+3. Linting                                                           *ale-lint*
+
+ALE's primary focus is on checking for problems with your code with various
+programs via some Vim code for integrating with those programs, referred to
+as 'linters.' ALE supports a wide array of programs for linting by default,
+but additional programs can be added easily by defining files in |runtimepath|
+with the filename pattern `ale_linters/<filetype>/<filename>.vim`. For more
+information on defining new linters, see the extensive documentation
+for |ale#linter#Define()|.
+
+Without any configuration, ALE will attempt to check all of the code for every
+file you open in Vim with all available tools by default. To see what ALE
+is doing, and what options have been set, try using the |:ALEInfo| command.
+
+Most of the linters ALE runs will check the Vim buffer you are editing instead
+of the file on disk. This allows you to check your code for errors before you
+have even saved your changes. ALE will check your code in the following
+circumstances, which can be configured with the associated options.
+
+* When you modify a buffer.                - |g:ale_lint_on_text_changed|
+* When you open a new or modified buffer.  - |g:ale_lint_on_enter|
+* When you save a buffer.                  - |g:ale_lint_on_save|
+* When the filetype changes for a buffer.  - |g:ale_lint_on_filetype_changed|
+* If ALE is used to check code manually.   - |:ALELint|
+
+In addition to the above options, ALE can also check buffers for errors when
+you leave insert mode with |g:ale_lint_on_insert_leave|, which is off by
+default. It is worth reading the documentation for every option.
+
+                                                        *ale-lint-file-linters*
+
+Some programs must be run against files which have been saved to disk, and
+simply do not support reading temporary files or stdin, either of which are
+required for ALE to be able to check for errors as you type. The programs
+which behave this way are documented in the lists and tables of supported
+programs. ALE will only lint files with these programs in the following
+circumstances.
+

+4. Fixing Problems                                                    *ale-fix*
+
+ALE can fix problems with files with the |ALEFix| command. When |ALEFix| is
+run, the variable |g:ale_fixers| will be read for getting a |List| of commands
+for filetypes, split on `.`, and the functions named in |g:ale_fixers| will be
+executed for fixing the errors.
+
+The |ALEFixSuggest| command can be used to suggest tools that be used to
+fix problems for the current buffer.
+
+The values for `g:ale_fixers` can be a list of |String|, |Funcref|, or
+|lambda| values. String values must either name a function, or a short name
+for a function set in the ALE fixer registry.
+
+Each function for fixing errors must accept either one argument `(buffer)` or
+two arguments `(buffer, lines)`, representing the buffer being fixed and the
+lines to fix. The functions must return either `0`, for changing nothing, a
+|List| for new lines to set, or a |Dictionary| for describing a command to be
+run in the background.
+
+Functions receiving a variable number of arguments will not receive the second
+argument `lines`. Functions should name two arguments if the `lines` argument
+is desired. This is required to avoid unnecessary copying of the lines of
+the buffers being checked.
+
+When a |Dictionary| is returned for an |ALEFix| callback, the following keys
+are supported for running the commands.
+
+  `command`             A |String| for the command to run. This key is required.
+
+                      When `%t` is included in a command string, a temporary
+                      file will be created, containing the lines from the file
+                      after previous adjustment have been done.
+
+  `read_temporary_file` When set to `1`, ALE will read the contents of the
+                      temporary file created for `%t`. This option can be used
+                      for commands which need to modify some file on disk in
+                      order to fix files.
+
+                                                        *ale-fix-configuration*
+
+Synchronous functions and asynchronous jobs will be run in a sequence for
+fixing files, and can be combined. For example:
+>
+  let g:ale_fixers = {
+  \   'javascript': [
+  \       'DoSomething',
+  \       'eslint',
+  \       {buffer, lines -> filter(lines, 'v:val !=~ ''^\s*//''')},
+  \   ],
+  \}
+
+  ALEFix
+<
+The above example will call a function called `DoSomething` which could act
+upon some lines immediately, then run `eslint` from the ALE registry, and
+then call a lambda function which will remove every single line comment
+from the file.
+
+For convenience, a plug mapping is defined for |ALEFix|, so you can set up a
+keybind easily for fixing files. >
+
+  " Bind F8 to fixing problems with ALE
+  nmap <F8> <Plug>(ale_fix)
+<

+by default.
+
+|g:ale_fix_on_save| - Fix files when they are saved.

+
+ALE offers some limited support for automatic completion of code while you
+type. Completion is only supported via Language Server Protocol servers which
+ALE can connect to for linting, which can offer good built-in support for
+suggesting completion information. ALE will only suggest symbols for
+completion for LSP linters that are enabled.
+
+NOTE: At the moment, only `tsserver` for TypeScript code is supported for
+completion.
+
+Suggestions will be made while you type after completion is enabled.
+Completion can be enabled by setting |g:ale_completion_enabled| to `1`. The
+delay for completion can be configured with |g:ale_completion_delay|. ALE will
+only suggest so many possible matches for completion. The maximum number of
+items can be controlled with |g:ale_completion_max_suggestions|.
