====== Update Express Generator ======


Fetcher can check for a newer Express Generator version and optionally install it.

===== Update options =====

<code ini>
check_for_update      = true
automatic_update      = true
update_check_interval = 24
</code>

Option behavior:

  * ''check_for_update''
    Enables update checks when fetcher runs.
  * ''automatic_update''
    If a newer version exists, fetcher downloads and installs it automatically.
  * ''update_check_interval''
    Minimum hours between update checks.


===== Recommended profiles =====

==== Fully automatic (default) ====

<code ini>
check_for_update      = true
automatic_update      = true
update_check_interval = 24
</code>

Use when you want Express Generator to stay current with no manual steps.

==== Notify only ====

<code ini>
check_for_update      = true
automatic_update      = false
update_check_interval = 24
</code>

Use when updates must be reviewed before installation.

==== No update checks ====

<code ini>
check_for_update = false
</code>

Use in controlled environments where versions are pinned externally.


===== CLI examples =====

Check for updates but do not auto-install:

<code bash>
node ./bin/fetch.js --check-for-update true --automatic-update false --update-check-interval 0
</code>

Disable update checks for this run:

<code bash>
node ./bin/fetch.js --check-for-update false
</code>

Force an update check immediately:

<code bash>
node ./bin/fetch.js --check-for-update true --update-check-interval 0
</code>


===== Notes =====

  * ''update_check_interval'' is measured in hours.
  * The last check timestamp is stored in ''./bin/res/update-check.json''.
  * Update checks run only when ''check_for_update'' is enabled.
  * Auto-update replaces files in the ''./bin'' folder.
  * Keep your custom changes in user settings files and pass them with ''--settings''.
