.SH OPERATIONAL NOTES
.PP
.IP 1. 4
The database file is stored in:
  - \fI$XDG_DATA_HOME/buku/bookmarks.db\fR, if XDG_DATA_HOME is defined (first preference), or
  - \fI$HOME/.local/share/buku/bookmarks.db\fR, if HOME is defined (second preference), or
  - \fI%APPDATA%\\buku\\bookmarks.db\fR, if you are on Windows, or
  - the current directory.
.PP
.IP 2. 4
If the URL contains characters like ';', '&' or brackets they may be interpreted specially by the shell. To avoid it, add the URL within single or double quotes ('/").
.PP
.IP 3. 4
URLs are unique in DB. The same URL cannot be added twice.
.PP
.IP 4. 4
Bookmarks with immutable titles are listed with '(L)' after the title.
.PP
.IP 5. 4
\fBTags\fR:
  - Comma (',') is the tag delimiter in DB. A tag cannot have comma(s) in it. Tags are filtered (for unique tags) and sorted. Tags are stored in lower case and can be replaced, appended or deleted.
  - Page keywords having a word to comma ratio > 3 are appended to description rather than tags.
  - Parent folder (and subfolder) names are converted to all-lowercase tags during bookmarks HTML import.
  - Releases prior to v2.7 support both capital and lower cases in tags. From v2.7 all tags are stored in lowercase. An undocumented option --fixtags is introduced to modify the older tags. It also fixes another issue where the same tag appears multiple times in the tagset of a record. Run \fBbuku --fixtags\fR once.
  - Tags can be edited from the prompt very easily using '>>' (append), '>' (overwrite) and '<<' (remove) symbols. The LHS of the operands denotes the indices and ranges of tags to apply (as listed by --tag or key 't' at prompt) and the RHS denotes the actual DB indices and ranges of the bookmarks to apply the change to.
.PP
.IP 6. 4
\fBUpdate\fR operation:
  - If --title, --tag or --comment is passed without argument, clear the corresponding field from DB.
  - If --url is passed (and --title is omitted), update the title from web using the URL. Description is updated (if --comment is omitted). Tags remain untouched.
  - If indices are passed without any other options (--url, --title, --tag, --comment and --immutable), read the URLs from DB and update titles, description and append tags from web. Bookmarks marked immutable are skipped.
  - Can update bookmarks matching a search, when combined with any of the search options and no arguments to update are passed.
.PP
.IP 7. 4
\fBDelete\fR operation:
  - When a record is deleted, the last record is moved to the index.
  - Delete doesn't work with range and indices provided together as arguments. It's an intentional decision to avoid extra sorting, in-range checks and to keep the auto-DB compaction functionality intact. On the same lines, indices are deleted in descending order.
  - Can delete bookmarks matching a search, when combined with any of the search options and no arguments to delete are passed.
.PP
.IP 8. 4
\fBSearch\fR works in mysterious ways:
  - Case-insensitive.
  - Matches words in URL, title and tags.
  - --sany : match any of the keywords in URL, title or tags. Default search option.
  - --sall : match all the keywords in URL, title or tags.
  - --deep : match \fBsubstrings\fR (`match` matches `rematched`) in URL, title and tags.
  - --sreg : match a regular expression (ignores --deep).
  - --stag : search bookmarks by tags, or list all tags alphabetically with usage count (if no arguments). Delimit the list of tags in the query with `,` to search for bookmarks that match ANY of the listed tags. Delimit tags with `+` to search for bookmarks that match ALL of the listed tags. Note that `,` and `+` cannot be used together in the same search. Exclude bookmarks matching certain tags from the results by using ` - ` followed by the tags. Note that the ` - ` operator and the ` + ` delimiter must be space separated: ` - ` instead of `-` and ` + ` instead of `+`. This is to distinguish them from hyphenated tags (e.g., `some-tag-name`) and tags with '+'s (e.g., `some+tag+name`).
  - Search for keywords along with tag filtering is possible. Two searches are issued (one for keywords and another for tags) and the intersection of the 2 sets is returned as the resultset.
  - Search results are indexed incrementally. This index is different from actual database index of a bookmark record which is shown within '[]' after the title.
  - Results for \fIany\fR keyword matches are ordered by the number of keyword matches - results matching more keywords (\fImatch score\fR) will appear earlier in the list. Results having the same number of matches will be ranked by their record DB index. If only one keyword is searched, results will be ordered by DB index, since all matching records will have the same \fImatch score\fR.
.PP
.IP 9. 4
\fBImport\fR:
  - Auto-import looks in the default installation path and default user profile.
  - URLs starting with `place:`, `file://` and `apt:` are ignored during import.
  - Parent folder (and subfolder) names are automatically imported as tags if --tacit is used.
  - Tags are merged even if bookmark URL exists when --tacit is used.
  - JSON files exported from browser can be imported. Export to JSON is not supported.
.PP
.IP 10. 4
\fBEncryption\fR is optional and manual. AES256 algorithm is used. To use encryption, the database file should be unlocked (-k) before using \fBbuku\fR and locked (-l) afterwards. Between these 2 operations, the database file lies unencrypted on the disk, and NOT in memory. Also, note that the database file is \fBunencrypted on creation\fR.
.PP
.IP 11. 4
\fBEditor\fR support:
  - A single bookmark can be edited before adding. The editor can be set using the environment variable *EDITOR* or by explicitly specifying the editor. The latter takes precedence. If -a is used along with -w, the details are populated in the editor template.
  - In case of edit and update (a single bookmark), the existing record details are fetched from DB and populated in the editor template. The environment variable EDITOR must be set. Note that -u works independently of -w.
  - All lines beginning with "#" will be stripped. Then line 1 will be treated as the URL, line 2 will be the title, line 3 will be comma separated tags, and the rest of the lines will be parsed as descriptions.
.PP
.IP 12. 4
\fBProxy\fR support: please refer to the \fBENVIRONMENT\fR section.
.PP
.IP 13. 4
\fBAlternative DB file\fR:
  - The option --db (to specify an alternative database file location) is app-only. Manual usage is prone to issues arising from human error.
  - Note that this option is useful if you want to store the db file in cloud synced location. Another mechanism could be to have the db file synced and create a symlink to it at the default location.
.SH GENERAL OPTIONS

Note that

Bright colors (implemented as \\x1b[90m - \\x1b[97m) may not be available in all color-capable terminal emulators;
.IP - 2
Some terminal emulators draw bold text in bright colors instead;
.IP - 2
Some terminal emulators only distinguish between bold and bright colors via a default-off switch.
.TP
Please consult the manual of your terminal emulator as well as \fIhttps://en.wikipedia.org/wiki/ANSI_escape_code\fR for details.
