I've seen there are some descriptive paragraphs which have grave accents used as quoting of commands: alire/src/alr/alr-commands-publish.ads Line 34 in 2e3a520 This has a positive (involuntary?) impact in the formatting of the markdown version. If this is considered valid also for the terminal, shouldn't this be standardized and use the same quoting for similar paragraphs containing natural language and command lines? Other examples of grave accent quoting: On the contrary, see, for example, these other places where apostrophe quoting has been used and could be changed: Nevertheless, my initial approach was that these text paragraphs should use something like I won't proceed with any of these changes until I get your feedback. |

Continuation from the closed pull request at clic: alire-project/clic#29 (comment) I've made a test with pandoc and the output is already pretty acceptable. The kind of errors that are shown, are already present in the markdown output and they are the kind of part where a code formatting should be applied, as I mention in The man page has to be copied to a file and displayed running: The man pages maybe should be split per command, so a different argument for .\" Automatically generated by Pandoc 2.9.2.1

.SS DESCRIPTION
.PP
Provides a command line interface to the Alire configuration option
files.
.PP
Option names (keys) can use lowercase and uppercase alphanumeric
characters from the Latin alphabet.
Underscores and dashes can also be used except as first or last
character.
Dot `.' is used to specify sub-categories, e.g.
`user.name' or `user.email'.
.PP
Option values can be integers, float, Boolean (true or false) or
strings.
The type detection is automatic, e.g.\ 10 is integer, 10.1 is float,
true is Boolean.
You can force a value to be set a string by using double-quotes, e.g.
\[lq]10.1\[rq] or \[lq]true\[rq].
Extra type checking is used for built-in options (see below).
.PP
Built-in configuration options:
.IP \[bu] 2
dependencies.shared [Boolean][Default:FALSE] When true, dependencies are
downloaded and built in a shared location inside the global cache.
When false, dependencies are sandboxed in each workspace.
.IP \[bu] 2
distribution.disable_detection [Boolean][Default:FALSE] If true, Alire
will report an unknown distribution and will not attempt to use the
system package manager.
.IP \[bu] 2
editor.cmd [String][Default:gnatstudio -P ${GPR_FILE}] Editor command
and arguments for editing crate code (alr edit).
The executables and arguments are separated by a single space character.
The token ${GPR_FILE} is replaced by a path to the project file to open.
.IP \[bu] 2
index.auto_community [Boolean][Default:TRUE] When unset or true, the
community index will be added automatically when required if no other
index is configured.
.IP \[bu] 2
index.host [String][Default:https://github.com] URL of the community
index host
.IP \[bu] 2
index.owner [String][Default:alire-project] Owner of the index
repository (GitHub user/org).
.IP \[bu] 2
index.repository_name [String][Default:alire-index] Name of the index
repository.
.IP \[bu] 2
solver.autonarrow [Boolean][Default:TRUE] If true, \f[C]alr with\f[R]
will replace `any' dependencies with the appropriate caret/tilde
dependency.
.IP \[bu] 2
toolchain.assistant [Boolean][Default:TRUE] If true, and assistant to
select the default toolchain will run when first needed.
.IP \[bu] 2
update.manually_only [Boolean][Default:FALSE] If true, Alire will not
attempt to update dependencies even after the manifest is manually
edited, or when no valid solution has been ever computed.
All updates have to be manually requested through \f[C]alr update\f[R]
.IP \[bu] 2
user.email [Email address][Default:] User email address.
Used for the authors and maintainers field of a new crate.
.IP \[bu] 2
user.github_login [GitHub login][Default:] User GitHub login/username.
Used to for the maintainers-logins field of a new crate.
.IP \[bu] 2
user.name [String][Default:] User full name.
Used for the authors and maintainers field of a new crate.
.IP \[bu] 2
warning.caret [Boolean][Default:TRUE] If true, Alire will warn about the
use of caret (\[ha]) for pre-1 dependencies, for which tilde (\[ti]) is
recommended instead.
.IP \[bu] 2
warning.old_index [Boolean][Default:TRUE] If unset or true, a warning
will be emitted when using a compatible index with a lower version than
the newest known.

.SS DESCRIPTION
.PP
Manages installations of releases to a common prefix.
The default install location is /home/mgr/.alire
.PP
Installation prefixes are intended to make binaries or dynamic libraries
available outside of the Alire environment, normally by adding the /bin
folder to the user\[cq]s path.
.PP
Although Alire will vet trivially detectable conflicts (e.g., trying to
install two executable release with different versions), Alire is not
aware of the exact binary artifacts produced by compiled crates.
Thus, you are \[lq]on your own\[rq] in regard to the final consistency
of installations.
.PP
That said, binary crates from the Alire project (gnat, gnatprove,
gprbuild), as well as crates initialized with \f[C]alr\f[R] using
default templates, should be able to coexist in a same installation
prefix without issue.
.PP
You can use the \f[C]--force\f[R] to reinstall already installed
releases.

.PP
Download toolchain elements, like GNAT and gprbuild, in the shared cache
of the active configuration.
.PP
Run it without arguments to get a list of downloaded tools.
.PP
Use \f[C]--select\f[R] without arguments to run the assistant to select
the default toolchain for this configuration.
Adding \f[C]--local\f[R] will instead make the selection apply only to
the workspace (overriding a possible configuration- wide selection).
Giving one or more releases argument will skip the assistant and set the
release as the default.
.PP
Specify \f[C]--install/--uninstall\f[R] and one or more crates name with
optional version set to make available or remove a tool.
.PP
Run \f[C]alr help toolchains\f[R] for further information about
toolchain management and use.

.SS DESCRIPTION
.PP
Searches the given substring in crate names (or properties with
\f[C]-- property\f[R]), and shows the most recent release of matching
crates (unless \f[C]-- full\f[R] is specified).
.PP
Use \f[C]--crates\f[R] to get a simple list of only crate names and
descriptions.
Otherwise, besides version, description and release notes, a status
column with the following status flags is provided:
.PP
E: the release is externally provided.
S: the release is available through a system package.
U: the release is not available in the current platform.
X: the release has dependencies that cannot be resolved.
.PP
The reasons for unavailability (U) can be ascertained with `alr show ='.
.PP
Unresolvable releases (X) should not happen in platforms with assigned
maintainers.
Common reasons are missing system dependencies that have been phased out
by the platform without being updated yet in the community index.

.PP
Shows information found in the loaded indexes about a specific release
(see below to narrow the searched milestones).
By default, only direct dependencies are reported.
With \f[C]--solve\f[R], a full solution is resolved and reported in list
and graph form.
.PP
With \f[C]--external\f[R], the external definitions for a crate are
shown, instead of information about a particular release
.PP
The \f[C]--dependents\f[R] switch accepts these values: * direct
(default) shows direct dependents.
* all shows all dependents, including indirect ones, and all dependency
chains.
* shortest shows all dependents, including indirect ones, but only once,
and a shortest-length chain.

.SS DESCRIPTION
.PP
Invokes gprbuild to compile all targets in the current crate.
.PP
A build profile can be selected with the appropriate switch.
The profile is applied to the root release only, whereas dependencies
are built in release mode.
Use \f[C]--profiles\f[R] for more overrides.
.PP
\f[C]--profiles=*|%|<crate1>=<profile>[,<crate2>=<profile\f[R]>\&...]
Apply profiles to individual crates.
Use *= to set all profiles.
Use %= to set profiles of crates without a setting in a manifest only.
.PP
Running `alr build' without profile switches defaults to development
(root crate) + release (dependencies).
Indirect builds through, e.g., `alr run' will use the last `alr build'
configuration.

.PP
Alr sets up the environment variables (GPR_PROJECT_PATH, PATH, etc.) and
then spawns the given command.
.PP
This can be used to run tools or scripts on Alire projects.
.PP
The \[lq]-P\[rq] switch can be used to ask Alire to insert a \[lq]-P
\[rq] switch to the command arguments.
\[lq]-P\[rq] takes an optional position argument to specify where to
insert the extra switch.
\[lq]-P1\[rq] means first position, \[lq]-P2\[rq] second position, etc.
\[lq]-P-1\[rq] means last position, \[lq]-P-2\[rq] penultimate position,
etc.
\[lq]-P\[rq] equals \[lq]-P1\[rq].
For example \[lq]alr exec -P2 \[en] python3 main.py arg1\[rq] will run
the following command: [\[lq]python3\[rq], \[lq]main.py\[rq],
\[lq]-P\[rq], \[lq]crate.gpr\[rq], \[lq]arg1\[rq]]

.PP
Pin releases to a particular version.
By default, the current solution version is used.
A pinned release is not affected by automatic updates.
.PP
Without arguments, show existing pins.
.PP
Use \f[C]--all\f[R] to pin the whole current solution.
.PP
Specify a single crate to modify its pin.
.PP
Use the \f[C]--use\f[R] <PATH|URL> switch to use the target to fulfill a
dependency locally instead of looking for indexed releases.
An optional reference can be specified with \f[C]--commit\f[R]; the pin
will be frozen at the commit currently matching the reference.
Alternatively, a branch to track can be specified with
\f[C]--branch\f[R].
Use \f[C]alr update\f[R] to refresh the tracking pin contents.

.PP
Resolves unpinned dependencies using available indexes.
.PP
Invoked without arguments will consider all unpinned crates for
updating.
.PP
One or more crates can be given as argument, in which case only these
crates will be candidates for updating.
Requesting the update of a pinned crate is not allowed.

.SS DESCRIPTION
.PP
Inspect and manage dependencies.
.IP \[bu] 2
Inspecting dependencies: Run without arguments prints current
dependencies.
Use \f[C]--solve\f[R] to print the solution in use for these
dependencies.
.IP \[bu] 2
Adding dependencies from the command line: Dependencies are added by
giving their name, and removed by using the \f[C]--del\f[R] flag.
Dependencies cannot be simultaneously added and removed in a single
invocation.
.IP \[bu] 2
Adding dependencies pinned to external sources: When a single crate name
is accompanied by an \f[C]--use\f[R] PATH|URL argument, the crate is
always fulfilled for any required version by the sources found at the
given target.
An optional reference can be specified with \f[C]--commit\f[R]; the pin
will be frozen at the commit currently matching the reference.
Alternatively, a branch to track can be specified with
\f[C]--branch\f[R].
Use \f[C]alr update\f[R] to refresh the tracking pin contents.
.IP \[bu] 2
Adding dependencies from a GPR file: The project file given with
\f[C]--from\f[R] will be scanned looking for comments that contain the
sequence `alr with'.
These will be processed individually as if they had been given in the
command line, starting with no dependencies.
That is, only dependencies given in the GPR file will be preserved.
.PP
Example of GPR file contents:
.PP
with \[lq]libhello\[rq]; \[en] alr with libhello

URL is an optional path to a remote source archive, or a local or remote
git repository.
.PP
For the common use case of a github-hosted repository, issue
\f[C]alr publish\f[R] after committing and pushing the new release
version.
.PP
Use \f[C]--tar\f[R] to create a source archive ready to be uploaded.
.PP
Use \f[C]--manifest\f[R] to use metadata in a non-default file.
.PP
See the above link for help with other scenarios.
.SH Topics
.SS aliases
.SS User defined command aliases
.PP
Command aliases can be defined in local or global configuration.
.PP
For example the following command: \[lq]$ alr config \f[C]--set\f[R]
\f[C]--global\f[R] alias.graph `show \f[C]--graph\f[R]'\[rq] Defines a
global alias for the `show' command with a `\[en]graph' switch.
.PP
\[lq]$ alr graph\[rq] is equivalent to \[lq]alr show
\f[C]--graph\f[R]\[rq]
.SS identifiers
.SS Naming rules for crate and index names
.PP
Identifiers for crates and indexes must use lowercase alphanumeric
characters from the latin alphabet.
Underscores can also be used, except as the first character.
.PP
Length must be of 3 to 64 characters.
.SS toolchains
.SS Configuration and use of toolchains
.PP
Alire indexes binary releases of GNAT and gprbuild.
The compilers are indexed with their target name, e.g., gnat_native or
gnat_riscv_elf.
.PP
Use alr toolchain \f[C]--help\f[R] to obtain information about toolchain
management.
Alire can be configured to rely on a toolchain installed by the user in
the environment, or to use one of the indexed toolchains whenever
possible.
.PP
Some crates may override the default toolchain by specifying
dependencies on particular compiler crates, for example to use a
cross-compiler.
In this situation, a compiler already available (selected as default or
already installed) will take precedence over a compiler available in the
index.
.PP
See also https://alire.ada.dev/docs/#toolchains for additional details
about compiler dependencies and toolchain interactions.<!DOCTYPE html>

<p>Provides a command line interface to the Alire configuration option files.</p>
<p>Option names (keys) can use lowercase and uppercase alphanumeric characters from the Latin alphabet. Underscores and dashes can also be used except as first or last character. Dot ‘.’ is used to specify sub-categories, e.g. ‘user.name’ or ‘user.email’.</p>
<p>Option values can be integers, float, Boolean (true or false) or strings. The type detection is automatic, e.g. 10 is integer, 10.1 is float, true is Boolean. You can force a value to be set a string by using double-quotes, e.g. “10.1” or “true”. Extra type checking is used for built-in options (see below).</p>
<p>Built-in configuration options:</p>
<ul>
<li><p>dependencies.shared [Boolean][Default:FALSE] When true, dependencies are downloaded and built in a shared location inside the global cache. When false, dependencies are sandboxed in each workspace.</p></li>
<li><p>distribution.disable_detection [Boolean][Default:FALSE] If true, Alire will report an unknown distribution and will not attempt to use the system package manager.</p></li>
<li><p>editor.cmd [String][Default:gnatstudio -P ${GPR_FILE}] Editor command and arguments for editing crate code (alr edit). The executables and arguments are separated by a single space character. The token ${GPR_FILE} is replaced by a path to the project file to open.</p></li>
<li><p>index.auto_community [Boolean][Default:TRUE] When unset or true, the community index will be added automatically when required if no other index is configured.</p></li>
<li><p>index.host [String][Default:https://github.com] URL of the community index host</p></li>
<li><p>index.owner [String][Default:alire-project] Owner of the index repository (GitHub user/org).</p></li>
<li><p>index.repository_name [String][Default:alire-index] Name of the index repository.</p></li>
<li><p>solver.autonarrow [Boolean][Default:TRUE] If true, <code>alr with</code> will replace ‘any’ dependencies with the appropriate caret/tilde dependency.</p></li>
<li><p>toolchain.assistant [Boolean][Default:TRUE] If true, and assistant to select the default toolchain will run when first needed.</p></li>
<li><p>update.manually_only [Boolean][Default:FALSE] If true, Alire will not attempt to update dependencies even after the manifest is manually edited, or when no valid solution has been ever computed. All updates have to be manually requested through <code>alr update</code></p></li>
<li><p>user.email [Email address][Default:] User email address. Used for the authors and maintainers field of a new crate.</p></li>
<li><p>user.github_login [GitHub login][Default:] User GitHub login/username. Used to for the maintainers-logins field of a new crate.</p></li>
<li><p>user.name [String][Default:] User full name. Used for the authors and maintainers field of a new crate.</p></li>
<li><p>warning.caret [Boolean][Default:TRUE] If true, Alire will warn about the use of caret (^) for pre-1 dependencies, for which tilde (~) is recommended instead.</p></li>
<li><p>warning.old_index [Boolean][Default:TRUE] If unset or true, a warning will be emitted when using a compatible index with a lower version than the newest known.</p></li>

<h3 id="description-2">DESCRIPTION</h3>
<p>Manages installations of releases to a common prefix. The default install location is /home/mgr/.alire</p>
<p>Installation prefixes are intended to make binaries or dynamic libraries available outside of the Alire environment, normally by adding the <prefix>/bin folder to the user’s path.</p>
<p>Although Alire will vet trivially detectable conflicts (e.g., trying to install two executable release with different versions), Alire is not aware of the exact binary artifacts produced by compiled crates. Thus, you are “on your own” in regard to the final consistency of installations.</p>
<p>That said, binary crates from the Alire project (gnat, gnatprove, gprbuild), as well as crates initialized with <code>alr</code> using default templates, should be able to coexist in a same installation prefix without issue.</p>
<p>You can use the <code>--force</code> to reinstall already installed releases.</p>

<h3 id="description-18">DESCRIPTION</h3>
<p>Inspect and manage dependencies.</p>
<ul>
<li><p>Inspecting dependencies: Run without arguments prints current dependencies. Use <code>--solve</code> to print the solution in use for these dependencies.</p></li>
<li><p>Adding dependencies from the command line: Dependencies are added by giving their name, and removed by using the <code>--del</code> flag. Dependencies cannot be simultaneously added and removed in a single invocation.</p></li>
<li><p>Adding dependencies pinned to external sources: When a single crate name is accompanied by an <code>--use</code> PATH|URL argument, the crate is always fulfilled for any required version by the sources found at the given target. An optional reference can be specified with <code>--commit</code>; the pin will be frozen at the commit currently matching the reference. Alternatively, a branch to track can be specified with <code>--branch</code>. Use <code>alr update</code> to refresh the tracking pin contents.</p></li>
<li><p>Adding dependencies from a GPR file: The project file given with <code>--from</code> will be scanned looking for comments that contain the sequence ‘alr with’. These will be processed individually as if they had been given in the command line, starting with no dependencies. That is, only dependencies given in the GPR file will be preserved.</p></li>
</ul>
<p>Example of GPR file contents:</p>
<p>with “libhello”; – alr with libhello</p>

<p>Alire indexes binary releases of GNAT and gprbuild. The compilers are indexed with their target name, e.g., gnat_native or gnat_riscv_elf.</p>
<p>Use alr toolchain <code>--help</code> to obtain information about toolchain management. Alire can be configured to rely on a toolchain installed by the user in the environment, or to use one of the indexed toolchains whenever possible.</p>
<p>Some crates may override the default toolchain by specifying dependencies on particular compiler crates, for example to use a cross-compiler. In this situation, a compiler already available (selected as default or already installed) will take precedence over a compiler available in the index.</p>
<p>See also https://alire.ada.dev/docs/#toolchains for additional details about compiler dependencies and toolchain interactions.</p>

Yes, I started using the grave accents at some point for monospace things, e.g. terminal commands. But then, instead of putting the in there manually, they should be part of |
* Use `Formatter.Terminal` for command lines and switches not passed through `Hightlight_Switches` * Avoid any <placeholder> which is not quoted as code * Use consistent formatting for lists with "*" and not "-" * Use indentation as a way to get preformat in appropriate cases
# Conflicts: # deps/clic # src/alr/alr-commands.ads
Add a new line before lists * It can be read better in the terminal * It make the list work with `pandoc` Add new CLIC commit also for `pandoc`.
|
I've made an update to the three repositories to fix some of the problems that were still pending. Both the web and the pandoc output are working pretty well. See attached PDF and the PR alire-project/alire.ada.dev#32 for the web. There are still a pair of minor issues:
You probably want to review the changes to the terminal output, just in case something is not of your liking. Most visible change is that the usage line has the I don't know if I can fix the PR checks from my side, since it is related to the commits of the dependencies not being yet in your repositories. Unless you have ideas about these points that I could include, the pull requests are ready for your review. |
When the line has three digits, the space is not present. Example: [Alr.Commands.Dev.Execute] (alr-commands-dev.adb:32 ) debug: In dev --filter versus [Alr.Commands.Dev.Execute] (alr-commands-dev.adb:100) debug: In dev --filter
|
By the way, I just saw that the Debian distribution already has man pages for Alire. I don't know if their work is automatic or semi-automatic, but they have this note:
https://manpages.debian.org/testing/alire/alr.1.en.html I mention this because I was experimenting with tables, and it might be feasible to get markdown tables for alignment to work on Jekyll but not for pandoc at the same time, unless headers are added to them. The reason is that markdown is not a fully defined standard, after all. For example, this table without actual header works on Jekyll, but not on pandoc (or github). ### OPTIONS
|`--list` |List configuration options |
|`--show-origin` |Show origin of configuration values in `--list` |
|`--get` |Print value of a configuration option |
|`--set` |Set a configuration option |
|`--unset` |Unset a configuration option |
|`--global` |Set and Unset global configuration instead of the local one|
|`--builtins-doc`|Print Markdown list of built-in configuration options |
But remove the blank line between the section heading and the table and everything will get broken, so it might be working by chance. This would work for all (although with borders on GitHub): ### OPTIONS
|Switch |Description |
|----------------|-----------------------------------------------------------|
|`--list` |List configuration options |
|`--show-origin` |Show origin of configuration values in `--list` |
|`--get` |Print value of a configuration option |
|`--set` |Set a configuration option |
|`--unset` |Unset a configuration option |
|`--global` |Set and Unset global configuration instead of the local one|
|`--builtins-doc`|Print Markdown list of built-in configuration options |Conclusion: supporting aligment could be done in Jekyll (adding a blank line to separate from the section heading, which should be avoided for the terminal) but not for Pandoc, unless a full header is added. The option without header is a bit messy and the one with header too verbose, so I'd leave it as is, but if you prefer with alignment, I could implement any of the two. |
