DEPRECATION

setHeadersto set column namesaddRowto add a row to the tableaddRowsto add multiple rows at oncesuggestWidthsto suggest widths for each column
options and styles
- cellEdge controls the the corners of each cell default is
+ - colSeparator is the separator after each column set to
|by default - rowSeparator is the separator between rows and is set to
-by default - separateRows is option to add a row separator after rendering each row or not.
Examples
when isMainModule:
var t = newAsciiTable()
t.tableWidth = 80
t.setHeaders(@["ID", "Name", "Date"])
t.addRow(@["1", "Aaaa", "2018-10-2"])
t.addRow(@["2", "bbvbbba", "2018-10-2"])
t.addRow(@["399", "CCC", "1018-5-2"])
printTable(t)
should render
+---------------------------+---------------------------+---------------------------+
|ID |Name |Date |
+---------------------------+---------------------------+---------------------------+
|1 |Aaaa |2018-10-2 |
+---------------------------+---------------------------+---------------------------+
|2 |bbvbbba |2018-10-2 |
+---------------------------+---------------------------+---------------------------+
|399 |CCC |1018-5-2 |
+---------------------------+---------------------------+---------------------------+
t.tableWidth = 0
printTable(t)
+---+-------+---------+
|ID |Name |Date |
+---+-------+---------+
|1 |Aaaa |2018-10-2|
+---+-------+---------+
|2 |bbvbbba|2018-10-2|
+---+-------+---------+
|399|CCC |1018-5-2 |
+---+-------+---------+
and if you don't want separateRows
t.tableWidth = 0
t.separateRows = false
printTable(t)
+---+-------+---------+
|ID |Name |Date |
+---+-------+---------+
|1 |Aaaa |2018-10-2|
|2 |bbvbbba|2018-10-2|
|399|CCC |1018-5-2 |
+---+-------+---------+
and to suggest widths for columns
t.reset()
t.suggestWidths(@[10, 80, 30])
t.setHeaders(@["ID", "Name", "Date"])
t.addRow(@["1", "Aaaa", "2018-10-2"])
t.addRow(@["2", "bbvbbba", "2018-10-2"])
t.addRow(@["399", "CCC", "1018-5-2"])
printTable(t)
you will see
+----------+--------------------------------------------------------------------------------+------------------------------+
|ID |Name |Date |
+----------+--------------------------------------------------------------------------------+------------------------------+
|1 |Aaaa |2018-10-2 |
+----------+--------------------------------------------------------------------------------+------------------------------+
|2 |bbvbbba |2018-10-2 |
+----------+--------------------------------------------------------------------------------+------------------------------+
|399 |CCC |1018-5-2 |
+----------+--------------------------------------------------------------------------------+------------------------------+
Why
I couldn't find any terminal ascii table library for nim and I found myself writing horrible code like this
var widths = @[0,0,0,0] #id, name, ports, root
for k, v in info:
if len($v.id) > widths[0]:
widths[0] = len($v.id)
if len($v.name) > widths[1]:
widths[1] = len($v.name)
if len($v.ports) > widths[2]:
widths[2] = len($v.ports)
if len($v.root) > widths[3]:
widths[3] = len($v.root)
var sumWidths = 0
for w in widths:
sumWidths += w
echo "-".repeat(sumWidths)
let extraPadding = 5
echo "| ID" & " ".repeat(widths[0]+ extraPadding-4) & "| Name" & " ".repeat(widths[1]+extraPadding-6) & "| Ports" & " ".repeat(widths[2]+extraPadding-6 ) & "| Root" & " ".repeat(widths[3]-6)
echo "-".repeat(sumWidths)
for k, v in info:
let nroot = replace(v.root, "https://hub.grid.tf/", "").strip()
echo "|" & $v.id & " ".repeat(widths[0]-len($v.id)-1 + extraPadding) & "|" & v.name & " ".repeat(widths[1]-len(v.name)-1 + extraPadding) & "|" & v.ports & " ".repeat(widths[2]-len(v.ports)+extraPadding) & "|" & nroot & " ".repeat(widths[3]-len(v.root)+ extraPadding-2) & "|"
echo "-".repeat(sumWidths)
result = ""
