LIST

The LIST keyword retrieves a directory listing from the bot's drive storage, returning information about files and subdirectories.

Syntax

files = LIST "path/"
files = LIST "path/" FILTER "*.pdf"
files = LIST "path/" RECURSIVE

Parameters

Parameter	Type	Description
`path`	String	Directory path to list (must end with `/`)
`FILTER`	String	Optional glob pattern to filter results
`RECURSIVE`	Flag	Include files in subdirectories

Description

LIST returns an array of file and directory information from the specified path in the bot's storage. Each item in the result includes metadata such as name, size, type, and modification date.

Use cases include:

Browsing user uploads
Finding files matching patterns
Checking if files exist
Building file inventories
Processing batches of files

Examples

Basic Directory Listing

' List all files in a directory
files = LIST "documents/"

FOR EACH file IN files
    TALK file.name + " (" + file.size + " bytes)"
NEXT

Filter by Extension

' List only PDF files
pdfs = LIST "documents/" FILTER "*.pdf"

TALK "Found " + LEN(pdfs) + " PDF files"

FOR EACH pdf IN pdfs
    TALK "- " + pdf.name
NEXT

Recursive Listing

' List all files including subdirectories
all_files = LIST "uploads/" RECURSIVE

TALK "Total files: " + LEN(all_files)

Check File Exists

' Check if a specific file exists
files = LIST "reports/"

found = false
FOR EACH file IN files
    IF file.name = "monthly-report.pdf" THEN
        found = true
        EXIT FOR
    END IF
NEXT

IF found THEN
    TALK "Report found!"
ELSE
    TALK "Report not found. Would you like me to generate one?"
END IF

Find Recent Files

' List files modified in last 24 hours
files = LIST "inbox/"
yesterday = DATEADD(NOW(), -1, "day")

recent = FILTER files WHERE modified > yesterday

TALK "You have " + LEN(recent) + " new files since yesterday"

Calculate Folder Size

' Sum up total size of files in folder
files = LIST "backups/" RECURSIVE

total_size = 0
FOR EACH file IN files
    total_size = total_size + file.size
NEXT

size_mb = total_size / 1048576
TALK "Backup folder size: " + FORMAT(size_mb, "#,##0.00") + " MB"

Process All Files of Type

' Process all CSV files in a folder
csv_files = LIST "imports/" FILTER "*.csv"

FOR EACH csv_file IN csv_files
    data = READ "imports/" + csv_file.name AS TABLE
    ' Process each file...
    MOVE "imports/" + csv_file.name TO "processed/" + csv_file.name
NEXT

TALK "Processed " + LEN(csv_files) + " CSV files"

Return Value

Returns an array of file objects. Each object contains:

Property	Type	Description
`name`	String	File or directory name
`path`	String	Full path relative to storage root
`size`	Number	File size in bytes (0 for directories)
`type`	String	`file` or `directory`
`mime_type`	String	MIME type (e.g., `application/pdf`)
`modified`	DateTime	Last modification timestamp
`created`	DateTime	Creation timestamp

Example Result

files = LIST "documents/"

' files[0] might be:
' {
'   name: "report.pdf",
'   path: "documents/report.pdf",
'   size: 245678,
'   type: "file",
'   mime_type: "application/pdf",
'   modified: "2025-01-15T10:30:00Z",
'   created: "2025-01-10T09:00:00Z"
' }

Filter Patterns

Pattern	Matches
`*`	All files
`*.pdf`	All PDF files
`*.csv`	All CSV files
`report*`	Files starting with "report"
`2025`	Files containing "2025"
`.jpg,.png`	Multiple extensions

' Multiple extensions
images = LIST "photos/" FILTER "*.jpg,*.png,*.gif"

' Wildcard in name
reports = LIST "exports/" FILTER "sales-*"

Error Handling

ON ERROR RESUME NEXT

files = LIST "nonexistent-folder/"

IF ERROR THEN
    PRINT "List failed: " + ERROR_MESSAGE
    TALK "That folder doesn't exist."
ELSE IF LEN(files) = 0 THEN
    TALK "The folder is empty."
ELSE
    TALK "Found " + LEN(files) + " items"
END IF

Common Errors

Error	Cause	Solution
`PATH_NOT_FOUND`	Directory doesn't exist	Check path spelling
`NOT_A_DIRECTORY`	Path is a file, not folder	Add trailing `/`
`PERMISSION_DENIED`	Access blocked	Check permissions

Behavior Notes

Trailing slash required: Paths must end with / to indicate directory
Excludes hidden files: Files starting with . are excluded by default
Sorted alphabetically: Results are sorted by name
Non-recursive by default: Only lists immediate contents unless RECURSIVE specified

Configuration

No specific configuration required. Uses bot's standard drive settings from config.csv:

name,value
drive-provider,seaweedfs
drive-url,http://localhost:8333
drive-bucket,my-bot

READ — Read file contents
WRITE — Write file contents
COPY — Copy files
MOVE — Move or rename files
DELETE FILE — Remove files
UPLOAD — Upload files to storage

Summary

LIST retrieves directory contents from storage, returning detailed metadata about each file and subdirectory. Use it to browse files, find matching documents, check existence, calculate sizes, and process batches of files. Filter patterns and recursive options help narrow results to exactly what you need.
